Dragonchain Great Reddit Scaling Bake-Off Public Proposal
Dragonchain Public Proposal TL;DR:
Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and postsper Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625. Watch Joe walk through the entire proposal and answer questions onYouTube. This proposal is also available on the Dragonchain blog.
Hello Reddit and Ethereum community!
I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale. For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube. We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.
Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.
Response and PoC
In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.
A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks. 24 hours in 4 minutes (YouTube): 24 hours in 4 minutes The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period. Tooling to reproduce our demo is available here: https://github.com/dragonchain/spirit-bomb
Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.
Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired. Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.
An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity. TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block. TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.
Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain. With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times. We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment. Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.
Flexibility in Scaling
Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems. We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
LBRY - To allow users to deploy content natively to LBRY
MakerDAO to allow users to lend small amounts backed by their Reddit community points.
STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.
Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction. Dragonchain Fees Table
How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node. Getting started is easy...
Download Dragonchain’s dctl
Input three commands into a terminal
Build an image
More information can be found in our Get started documents.
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain. Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain. After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks. Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.
Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.
Costs and resources
Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD. For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments. Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.
This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users. Over a 5 day period, your scaling PoC should be able to handle: *100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes. Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum. Reddit Scaling on Ethereum
Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
Operational on-premises capabilities
Operational deployment to any datacenter
Over 700 independent Community Verification Nodes with proof of ownership
Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)
Usability Scaling solutions should have a simple end user experience.
Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node. Examples:
Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.
Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users. All of Reddit's Transactions on Blockchain (month) Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees. Reddit Internal Token Transaction Fees Reddit Ethereum Token Transaction Fees When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
In a combination of the above, customers could cover aggregated fees.
Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.
Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here. Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here. In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here. A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.
Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.
Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.
Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible APIs should be well documented and stable
Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected. Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.
Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.
Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR. Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.
Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.
Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.
Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw
Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.
A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.
Bonus points Public, third-party implementation review available or in progress
Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.
Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.
One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).
Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!
Disney Releases Blockchain Platform as Open Source
The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group. https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html
In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney. Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
Obtain VP support and approval for the release
Verify ownership of the software to be released
Verify that no proprietary content would be released
Convince the organization that there was a value to the open source community
Convince the organization that there was a value to Disney
Offer the plan for ongoing maintenance of the project outside of Disney
Itemize competing projects
Verify no conflict of interest
Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
Obtain legal approval
Approval from corporate, parks, and other business units
Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
Trademark searches conducted for the selected name Dragonchain
Obtain IT security approval
Manual review of OSS components conducted
OWASP Dependency and Vulnerability Check Conducted
Obtain technical (software) approval
Offer management, process, and financial plans for the maintenance of the project.
Meet list of items to be addressed before release
Remove all Disney project references and scripts
Create a public distribution list for email communications
Remove Roets’ direct and internal contact information
Create public Slack channel and move from Disney slack channels
Create proper labels for issue tracking
Rename internal private Github repository
Add informative description to Github page
Expand README.md with more specific information
Add information beyond current “Blockchains are Magic”
Add getting started sections and info on cloning/forking the project
Add installation details
Add uninstall process
Add unit, functional, and integration test information
Detail how to contribute and get involved
Describe the git workflow that the project will use
Move to public, non-Disney git repository (Github or Bitbucket)
Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney. The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal
https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44 We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution! Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality. Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining. This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.
Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.
Syscoin + Matic Integration
Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both. Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.
Total cost for these 100k transactions: $0.63 USD See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing: ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37) Syscoin price: $0.11 Snapshot of live fee comparison chart Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions. Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.
Tools to simplify using Syscoin Bridge as a service with dapps and wallets will be released some time after implementation of Syscoin Core 4.2. These will be based upon the same processes which are automated in the current live Sysethereum Dapp that is functioning with the Syscoin mainnet.
The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms. The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.
Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.
Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).
Unique fee-market that is more efficient for microtransaction redemption and settlement
Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
Provides high throughput and secure fulfillment even if blocks are full
Probabilistic and interactive
99.9999% security assurance within 10 seconds
Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus
Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.
Syscoin 3.0 White Paper (4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
SHA256 merge mined with Bitcoin
UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
Z-DAG on asset layer, bridge to Ethereum on asset layer
On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.
Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask. Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2. Current supported wallets Syscoin Spark Desktop Syscoin-Qt
Theory Every trade execution by law of Central Limit Order Book logic has both a "maker" and a "taker" side from orders created. Every "maker" order has an event pushed to the "OrderBook" websocket stream. The API documentation in all cases of exchanges used indicates real-time pushing of updated data (we did not use streams where there was indication of 1000ms or so delays). So the methodology used throughout is to programmatically watch: - The order book best bid/offer - The raw trade feed Then look for trades which occur inbetween the bid/ask. This would indicate a trade took place which no one else was able to execute because the trade never appeared on the order book for anyone to be able to see, to then take. It is known that some exchanges are just not good at reporting the orderbook data and trade data in synch, or they do not provide detailed enough information of event timestamp/id to be able to resolve suspicious data. The scripts here compute both Fake Trades Count vs Legit Trades Count, as well as Fake Volume vs. Legit Volume. Feel free to request an exchange you use to be analysed using our methodology and we'll be happy to post it along with results.
Some results (also from the GitHub repository):
Volume executed between the spread (_o_) ?
Approx 30% of volume executes between the spread
Approx 2-3% of volume executes between the spread
Tested over a 12h period
within margin of error for latency issues
PERFECT - Tested and no fake volume identified
Exchange has hidden orders so test is non applicable
Weekly Update: Parachute Townhall, Welcome $GET to ParJar, Uptrennd reaches 50k members, Fantom on IncognitoChain... – 6 Dec - 12 Dec'19
Hi Parachuters! As part of 2 of 3 from today's rapid catch up series of pending updates, here’s your week at Parachute + partners (6 Dec - 12 Dec'19): As mentioned last week, Cap and Ice hosted a townhall to talk about where we are at and where we are heading along with ample feedback and Q&A from the community. We covered a lot of ground: "value hypothesis for ParJar, Product Market fit, and our growth approach for 2020...performance of two key PAR utility metrics, staking and gas, and how we see growth for each in 2020...questions from the community and reviewed upcoming community initiatives". Click here to catch up on all that happened. GET Protocol’s $GET token was added to ParJar this week. Belated Birthday wishes to Doc Vic from Cuba. Jason lost a 5k $PAR wager with Cap on Victor’s age. Haha. Congratulations to Martha for winning this week’s Parena. As per the latest Fantasy Premier League (#FPL) update shared by LordHades this week, he is still ruling the charts at the top with NovelCloud and Alexis hot on his heels. From next week, "You can now view your first opponent in the 2019/20 FPL Cup on the My Team page - under Leagues". While you slay those miles with the Parachute Running Club (which has done 44 miles so far BTW), here’s a podcast to listen to. Cap’s recommendation: "It's geared towards people building products - but super super useful to think about any products you use. Skip to like 9 minutes in to skip through all the advertiesments ". Yes, I know. Cap wouldn’t be Cap without typos. Typos FTW! Parachute townhall Parachute-themed shirts designed by Doc Vic and Alejandro on Doc’s birthday. These are sick! If you want to see yourself on the Parachute world map, make sure to enter your location here. The entries are anonymous. In this week's Parachute Fantasy Football League update, Hang is in the first position followed by Clinton and Andy. Connor made it to the playoffs and is now in 4th position. So it means farewell to Nilz, Ken, Kamo and Cap from this season. CoD mobile players, don't forget to join the Parachute WarZone hosted by Doc Vic from Cuba. I hear there's $PAR and $AMGO to be won! The TTR Hat Contest ended this week with some solid entries running in the lead. Epic creation Wendell! In this week’s creative prompt by Jason, Parachuters had to “do 3 nice things for a total stranger”. Basically, be a true blue Parachuter 😊. For this week's Two-for-Tuesday, Gian made it free-for-all. No theme. Post music as you wish and win 500 $PAR. Cool! Benjamin and Charlotte hosted trivias in TTR this week. Those were loads of fun! Andy announced the start of a College Football Bowl Game Pickem contest in Parachute. 100k $PAR prize pool. Doc Vic hosted another round of Champions League wager this week in TTR. So much epicness in one picture. Jose, you are a genius! Andy's Advent Calendar journey continues Catch up on the latest aXpire update and 20k AXPR burn here and here respectively. As you would already know, instead of pitting both startups against each other, XIO decided to accept both Opacity and Uptrennd into the incubator program and opened up staking for them. This marks the official launch of the XIO Blockchain Incubator and it’s been a roaring start with USD 7k worth of tokens locked up in one hour and Opacity portal getting oversubscribed in no time. Video instructions for staking can be found here. Read up on the startups here. In three days, the total staking crossed 1M XIO levels. Insane! That is a great metric to measure performance. How does the $XIO token play a role in all this? The crew explained in this tweet thread. And with that a series of related discussions got off starting with the possibility of self-nomination for startups. Have a sub-100 CMC project that you think should be part of the incubator? Don’t forget to tag them. Plus, a cool 25k $XIO giveaway was launched. Remember, meaningful conversation is always welcome at the incubator and more often than not, they get rewarded. Check out the latest update on the Birdchain App SMS feature along with an expanded list of supported countries. Silent Notary reduced the $LAW token requirement for running a Masternode from 100M to 20M this week. Russian research company sudexpa.ru also gave its vote of confidence to Silent Notary in terms of its immutability. Wibson Marketing Manager Fi Scantamburlo attended the Latin American Bitcoin Conference Uruguay to speak on Data privacy, monetisation and how Wibson helps achieve these. Opacity now allows shared file preview for uploaded docs. Shared File Preview on Opacity Fantom's foray into the Afghan Ministry of Health's efforts to fight counterfeit drugs and other public health initiatives were covered by Forbes this week. Last week, we shared that Sikoba's e-voting platform, Itugen, which is based on Fantom’s Lachesis consensus was released. This week, they published its technical whitepaper. With so many moving parts in the project and so much happening all around, a recap is always a welcome refresher to catch up. $FTM got listed on South Korea’s Coinone with a $KRW pairing. It was also integrated with the IncognitoChain project’s pDEX with a $pUSDT pairing (remember, Harmony was added to the same platform a few days back?). IncognitoChain allows cryptos to be transacted privately using sidechains including those coins/tokens which are not privacy-oriented. Fantom also launched a developer portal and technical documentation ahead of the XAR Network mainnet release. The interoperability bridge is out as well. This allows both ERC20 and BEP2 token holders to move their tokens to the XAR Network. The wallet allows both staking and delegation. For the guide to joining XAR Network as a validator node, click here. A simple guide to staking on XAR Network can be found here. The team also sat down for an AMA with COTI this week. Blockchain Magazine’s interview of Michael was published. Continuing with Uptrennd’s 24 Days of Celebrations started last week, this week they hosted an Escape Room contest and Photo contest. The latest $1UP tokenomics update can be seen here. After 11 months, the platform now has 50k users across 177 countries. Wowza! And wicked stats on the engagement metrics as well. Jeff’s interview with Crypto Beadles came out this week. A few entries for the Uptrennd Photo Contest Click here and here for the latest District Weekly and Dev Update from District0x. In case you missed this week’s Dapp Digest, you can watch it here. Aragon fans will be in for a treat since it features Aragon Co-Founder Luis Cuende as a special guest.

Hydro AMA Q&A Roundup with BitcoinMarkets (Slack), 15 June 2018
I've taken the liberty of rounding up all the questions and answers provided from Hydro's most recent AMA hosted with BitcoinMarkets incase you missed it. Enjoy! Hydro Q&A’s Q (knonsu): How does Snowflake relate to other identity protocols out there like Civic and uPort ? A.1 (Anurag): We see snowflake as existing a layer below these types of projects. Even without blockchain, identity is a broad term. Different people around the world have different forms of identity (state ID, country ID, social media IDs, etc). Civic, uPort, and other blockchain projects help to build specific types of an on-chain identity for a user; however those IDs are meaningful in different ways to different observers. For instance, imagine that a government or business builds a system that accepts Civic as a form of identity while another government/business only recognizes uPort identities. On top of this, certain systems only care about information tied to a user’s social media profile. A user can maintain one standard Snowflake as a base layer and set each of these different forms of identity as a resolver. Snowflake eliminates the need for global unanimous adoption of a singular identity standard and rather allows systems to build business logic off of identity standards they themselves recognize. Follow up Q (knonsu): thats cool. so its totally depends on the person/ institute utilizing it . One problem I found is how easy its to create fake identities (in their basic system). A.2 (Anurag): Yup! So people can conduct off-chain verifications to prove that you own a snowflake, and then tie an on-chain verification to your Snowflake. This links real-world KYC to your on-chain ID, so sure you could mint another snowflake, but that same party won't validate it again for you. Anyone who trusts that party would be able to accept their validations, and people who don't trust that party can rely on a different validator they do trust. — Q (kat): How big is the team working specifically on Hydro products? Can we get a numbers breakdown of engineers, biz dev, etc? Do you have plans to scale this team as the Hydro project develops? A.1 (Andy): Our Hydro team is 8 people. Devlopers (Myself and Noah) Product (Anurag and Shane) Community (Nahom) Founders (Mike and Matt) Partnerships/BizDev (Gunjan) The nice thing about Hydrogen though is we have a team of 30 people who we can leverage for different things. For example, Noah and I do not build mobile apps, but we have a front end team that is well versed in mobile app development. So while they are not directly on the Hydro team they do have a direct impact on Hydro. Hydrogen as a company is working to grow pretty rapidly. As we grow we will be filling out more positions in both blockchain and non-blockchain rolls. A.2 (Anurag): To add to Andy's answer - pretty much everyone working for Hydrogen helps out with Hydro in some way, whether via design, front-end development, API support, business discussion, etc. Here's our full team: https://www.hydrogenplatform.com/about — Q (rocket man): So in the age of ICOs, what motivated your team to not pursue that funding model and instead have a token distribution for developers? A (Andy): This was something that we spent a very long time considering and discussing. We spent a lot of resources (time, money & energy) trying to find the best solution for us going forward. When it was all said and done, we decided on an airdrop because of two main things, getting the token into the hands of people who will actually use it and regulatory concerns. We feel as though our distribution was the fairest approach that allowed for people with actual interest in the Hydro community to get involved. Overall, we have been very pleased with the level of community engagement from people who are interested in the utility of the Hydro token and we feel that a lot of this can be credited to our distribution strategy. — Q (matheussiq8): How hydro tokens will be used is still vague in the Snowflake whitepaper draft. Would the amount required to hold depend on the volume of API calls or some other parameter? For example, if I decide to implement raindrop and later snowflake in my small webshop would I need to hold the same amount of tokens as Binance (if they ever implement it of course…)? A (Noah): as always, the permissionlessness of public blockchains is a double-edged sword. smart contracts partially solve the problem by letting us enforce certain things on-chain (minimum token balances, signature validity, etc.), but there are limits. so, re. your specific question: in raindrop we do not vary the staking requirement across users, because that would necessarily involve value judgements we are not comfortable making as a centralized entity. however, there are two types of staking required for raindrop:
“institutional staking” requires entities who wish to sign up raindrop users *on their behalf* (i.e. passing new users’ addresses to the smart contract as parameters rather than new users transacting directly from their accounts) to stake a significant amount of hydro. these are the players we want to ensure are acting in the best interests of the community. in this model, hydro is simply one of many institutional stakers (where we sign up users on our kickass mobile app, which will be out soon).
“user staking” requires individuals who wish to sign up for raindrop on their own, i.e. transact directly with the smart contract, are able to do so by staking a much smaller amount of hydro.
What this all means for you, as a potential customer of our API, is that you don’t actually have to worry about the staking requirement or signing up users at all, and can simply use our API in conjunction with the Hydro app. Looking ahead to Snowflake, we have big plans to integrate increasing sophisticated uses of the token into the product. to some extent these are still up in the air, but rest assured that we are very focused on building a strong tokenomics structure. At a high level, the core token mechanism for snowflake will involve depositing tokens into the snowflake smart contract. These deposits will allow native staking/payment/incentive functionality denominated in hydro, without the hassle and worry of using ether with every call. — Q (Hodlall): When is raindrop Android app is releasing A (Andy): It is currently under development. We have a bunch of android phones with different OS on the way. It is hard to give a set date as we don't know what unforeseen issues could come up during the process though. All I can say is it is literally all that our mobile development team is working on — Q (Jeff_We_Cannafi): To piggyback on matheussiq8’s question, how do these identity tokens compare to existing forms of identity authentication, and do you anticipate the tokens themselves will be traded on exchanges? A (Andy): In my opinion, the main difference between what we are working towards and others like civic and uport is the scope of what we are aiming to do. We understand the value of having KYC on the blockchain and "One click signup", but really I think blockchain identity can be so much more than that. We are aiming to create a completely extendable and modular protocol which will allow for people to link anything they desire to their blockchain identity. Other protocols can tend to lean towards centralization (more a fault of current KYC procedures than the projects themselves) and we feel like this doesn't have to be the case. At least for now, something like KYC needs to have central authorities to verify user information, but why can't I also link my crypto kitties to my blockchain id or my linkedin profile to my blockchain id? Overall, what we are trying to build will easily allow for other blockchain developers to create robust identity solutions for whatever application they feel fit with Snowflake being at the core of that. We feel that this is crucial to eventually creating a completely open and decentralized identity system. Anyone can join and anyone can add what THEY consider to be an identity, but I only have to accept what I consider to be an identity. As far as trading, Snowflake Identity tokens will never be tradable. We feel that you identity should always be linked to you. This would be a dangerous road to a very easy black market for people's identities — Q (Jrock): What do you find the hardest part of pitching icos to regular companies? Also what do you think needs to happen for widespread crypto adoption? A (Shane): If you mean pitching Hydro to regular companies (we're not an ICO :stuck_out_tongue:), I would say the hardest part is getting the larger companies to move faster than a snail's pace. There are too many chefs in the kitchen and sometimes there is a lack of top-down strategy on blockchain, and it leaves large enterprises paralyzed sometimes. We try to resolve this by pitching how easy Hydro is to use, and how it connects to our broader Hydrogen ecosystem which can add value in a lot of places. In my opinion, widespread crypto adoption is going to be dependent on how parallelization plays out. If crypto's only option is to create a new parallel economy, widespread adoption is going to be slow and arduous and will take decades. However, if blockchain is able to be infused or layered on some of the current systems we have in place, the adoption will be much faster and broader. Ultimately this comes down to the usage of private vs public chains - the more private and centralized chains that get implemented, the farther the mainstream adoption will get pushed out. — Q (Luke): One aspect of Hydro that is beginning to really intrigue me are the potential use cases and dapps that can be built by external developers ontop of the Hydro protocol layers for each phase.
Having held various dev meetups and networking at various conferences, how are you finding the process of attracting developers to start building dapps and products in your ecosystem?
I understand the HCDP is getting updated with various new rules and bounties for dapps to be built, have you approached any developers yet with this new offer, and if so, how has the reception been?
How else do you intend to attract developers towards building on the Hydro protocols?
Through our events, we're mainly focused on helping expand the blockchain-focused developer community. We help give exposure to projects we find to be doing neat, innovative work in the space and keep ongoing dialogue with these communities.
In particular, to provide impetus to developers in the Hydro ecosystem, we've established the HCDP. The new process will involve putting out specific task requests. In the next week or so we'll have published specifications for dApps that can be built on top of Snowflake. We ourselves will not be building these dApps (they have nothing to do with Hydrogen's space as a company). This helps the ecosystem expand outside of Hydrogen-specific use-cases.
^^Through the above process to get them started. Eventually, we want the Hydro development process to be community-driven, so people are building on Hydro because it benefits their own programs and applications.
— Q (elmer_FUD): Hey Hydro Team! Here's a few question I've got for you after checking out the Raindrop and Snowflake whitepapers: How has your experience working in the Ethereum ecosystem been so far? While you are currently focused on the financial sector, would you consider actively marketing to other sectors such as healthcare and education in the future? It seems like both Raindrop and Snowflake would be useful in any environment that processes or stores sensitive data. Do you have plans to release official Raindrop SDK packages in other languages in the future? A bit more of a specific question: Raindrop is looks like a great product to use in a PCI-DSS environment - do you have thoughts on whether or not it the product is ready for primetime and do you think the industry standards and government regulation is prepared to handle these kinds of systems? A (Andy): Thanks for the questions! I'm gonna answer each in a separate response in this thread Overall it has been pretty solid. There is still a ton of room for growth in terms of documentation and stuff like that, but it is miles ahead of basically every other blockchain platform I have worked with. By far the biggest pain has been handling gas costs when considering the user experience. When trying to build actual products that people will want to use we feel that making it user friendly is something that many blockchain projects have not focused on nearly enough. Yeah certainly. We focus on fintech as that is where the rest of our companies APIs focus and that is where we have the most connections, but much of what we are building is much further reaching than that. Just as far as authentication goes, it really can apply to any major field and we intend to market it as such. We currently have Python and JS SDKs and have had a few java ones submitted through our community dev program. We have been revamping that program, but I anticipate we will be putting up more bounties for most major languages. I have considered making a few more myself, but we feel that they could be better suited as community projects. I completely agree. Raindrop and blockchain authentication when handling anything around payments is a great application. I think the biggest thing is actually convincing regulatory bodies that the protocols we have build are secure (since many can still be scared of blockchain). I definitely see this as a direct use case though — Q.1 (khonsu): What kind of banking relations do you have as a company, do they (banks) understand what you are trying to do ? Any VCs approached you for funding ? explain your business model. A.1 (Shane): Hydrogen has existed since 2009 in the form of Hedgeable. Hedgeable is a consumer-facing online investing app, and the tech behind it eventually spawned the Hydrogen tech platform. The story of how the transition happened goes essentially like this: (1) Hedgeable was disrupting banks & investing firms, (2) banks & investing firms started contacting us and seeing if we would help them digitize & automate their own businesses, (3) we started packaging up our tech and selling it to the banks. There was so much demand for this from financial institutions that we spun out a new company (Hydrogen). So to get back to your original question: we have some long-standing relationships in the banking & finance world, and to this day we have inbound leads from that space coming in every week. The key thing to keep in mind is that these institutions move extremely slowly, but they do understand the core value prop of our platform. Many of these firms are still in the midst of basic digitization efforts (i.e. moving from really slow offline processes to simple digital infrastructure), and that is the primary thing we are helping them with in early stages. But they are also keen on blockchain tech and they will naturally turn to us for that once they reach that point. We do have a few relationships with big financial companies in which Hydro/blockchain are already part of the discussion. We have revenue and don't need to rely on VCs. It is our general philosophy that building a business sustainably with actual clients and revenue is a good approach, but we would consider working with the right VC if that came to be and we wanted to scale more quickly. Right now, that is not an immediate concern for us. Our business model is in charging developers and enterprises to access the Hydrogen technology platform, which currently consists of products like Atom, Ion, and Hydro. Developers pay a per-user fee to hit our core APIs, while large enterprises negotiate custom (usually multi-year) contracts with us that typically include recurring revenue. Hydro, specifically, is being offered for free right now, as we attempt to gain adoption. But it is important to note that Hydro is just one piece of our ecosystem. Q.2 (Joleen): When you say fee - is this fee HYDRO? And when do you envisage HYDRO to no longer be offered FOC? A**.2 (Shane):** Sorry if it wasn't clear, I meant free to use our Hydro tech/APIs. The usage of HYDRO tokens within that is a separate issue - they still need to have HYDRO and we do not give it away for free to clients — Q (guacam0le): Adoption of an identity management solution (etc) would potentially involve a lot of identities. Further, scalability is a hot topic w/ blockchain. Is this a potential bottleneck? What is or might be done to address such? Tackling a competitor like Google or Authy's 2FA is no small feat. Also, not everyone is yet to embrace blockchain-based solutions. Have you found it difficult to interface with enterprises & get them excited about the idea of an overhaul? A (Anurag): nowflake is designed to be relatively low-load on the blockchain. A user needs to conduct a single transaction to “mint” their Snowflake. Once this is complete, they would need to complete one-time transactions to set each of their different forms of identities as resolvers as needed. A Snowflake is designed to be built out via resolvers over the duration of a user’s lifetime, so there’s never a need for heavy, frequent transactional capability. Similarly, smart contracts simply need to be set as resolvers by users; they do not themselves transact. Network scalability improvements will increase the range of use-cases for smart contracts that can be tied to Snowflake, but they aren’t a necessary prerequisite to some important early use-cases such as KYC platforms, and a few basic user-interaction platforms. As far as competition, we feel that current adoption of 2FA is, in general far short of where it should be, and any 2FA is generally better than none. Many businesses use text-message based 2FA, etc. In the short-run we are aiming toward pilot implementations with small businesses. To further this, we have put out many integration resources, guides, and documentation and accordingly believe implementation of Raindrop is a more straightforward workflow. As far as large enterprises go, Hydrogen has clients, so it is helpful for our project to have those connections. Large institutions are generally relatively slow-moving, but have expressed interest in using Raindrop, in particular for securing employee accounts. As the product grows, we may eventually move in this direction with Client Raindrop, but resources will always be available for any site that wants to adopt it. Additionally, we are looking into making a wordpress plug-in to make implementation much more accessible for many developers. -- Q (Smithymethods): I know Hydro is a fintech company, hydro plan to curb phishing and hacking to the bearest minimum we know that hacking is very rampant these days on MEW and with other wallet. Is Hydro planning to create a wallet that support hydro and other tokens using their raindrop Technology? As this will put an end to the problem of phishing and also promote hydro A (Noah): like everyone in the crypto space, we’re very worried about phishing, both personally and on behalf of all hydro token holders. we first want to reemphasize that preventing scams and fraud has to be a community-driven effort: teams and users need to be vigilant and promote best practices (never trusting links in public chats, shunning fake accounts, etc.). we are excited about raindrop’s potential to help combat phishing, though. we actually talked with someone about mycrypto about integrating raindrop into their desktop app. we’ve forked their code and are researching how feasible an implementation would be, stay tuned for updates! — Q (Hodlall): What security measures in place for hydro , I see lot of tokens being hacked nowadays , and money is stolen.. how does hydro make sure their team tokens are completely secured or as much as possible A (Andy): We all have been in crypto for a while and are pretty well versed in securing our stuff. Our tokens that are currently locked are in cold storage. Others are held in hardware wallets — Q (Joleen): We know that the Hydrogen platform is going to be used by CI Investments, a large insurance firm and a world top 20 bank, have these companies already begun purchasing Hydro OTC? A (Andy): This is something that we feel is best to be hands off with. It is really up to the discretion of our partners — Q (khonsu’s mumaffi): Ill be honest i have not yet fully read the whitepaper but id like to know other than investor growth do you truly believe there is interest in a model where users have to pay each time for access? How big do u expect this fee to be...for large companies dont you believe this is an unscalable practice? This may be a question more about most technologies built on token based economics too. A (Andy): So we have 2 different authentication protocols. One happens less often and is in the same vein as OAuth. This is called Server-Side Raindrop. This requires tokens to be sent. This protocol would only happen once per day for a business when accessing something like an API. I don't feel that these values are extremely high for increased security. Our second protocol, Client-Side Raindrop, functions much more like google auth. This logic actually does not require any tokens or even a transaction by the end user. It is 100% free for them to use and they will never have to pay for a transaction. Here the responsibility is on the implementing party to stake tokens. This allows them to onboard users and authenticate them. We felt it was crucial to have an authentication that did not have a cost per user login as it is not scalable — Q (khonsu’s mumaffi): Also do u plan to tokenise atom and ion too and if not covered earlier how big of an impact do the market conditions have on your business A (Anurag): Tough to say we're going to "tokenize" them since that word can carry a lot of different meanings in different contexts, but we do plan on integrating the entire Hydrogen platform with Hydro. This will most likely take the form of enhancements to systems leveraging Hydro. You can find a more detailed breakdown on our Hydro roadmap: https://medium.com/hydrogen-api/project-hydro-features-in-depth-look-39faa29f0d61 Market conditions don't really have an impact - we're still building the same tech on a day-to-day basis — Q (ghost): As a company in the space, do you see the fact that tokens have to be acquired on exchanges as an issue? How would a company that wants to develop with you acquire tokens? A (Anurag): Depends on what they're developing. dApps developing using Hydro smart contracts to create native functionality to their applications would need to acquire those tokens on their own; however, companies using the Hydrogen API will not. Here's a detailed article outlining when a developer would need the token for the Client Raindrop smart contract: https://medium.com/hydrogen-api/how-to-use-client-raindrop-without-using-the-hydrogen-api-bb04934ae293 — Q (jarederaj): Can you describe your stakeholders and give me a better sense of the exigency of your products? Who are you focused on serving with your platform and why are they motivated to use your platform? A (Shane): The Hydrogen platform serves developers and enterprises who want to build applications. We are specifically targeting the financial services sector, including banks, investing firms, insurance providers, and financial advisors. This includes large enterprises, individual developers, and startups. Our products are Atom (core digital infrastructure & engine for finserv), Ion (AutoML & business intelligence capabilities), and Hydro (blockchain & decentralization layer). Each has a different use case but these products combine to form an ecosystem of tools for developers to build sophisticated applications with. The main pain point we are addressing is the resources required to build, launch, and run a digital financial application. These resources include both time and money. Large enterprises have resources, but they waste years and millions of dollars trying to launch digital platforms (we've seen this first-hand), often unsuccessfully. The motivation here is obvious. Startups and smaller developers, on the other hand, do not have access to huge resource pools, so they are forced to look for solutions that make the process more efficient. In the same way that Wordpress makes launching a blog easy and also allows for extended functionality, Hydrogen makes launching fintech application easy. — Q (shujjishah): When the app will be released??? A (Anurag): We're going through our mobile development very iteratively. Since we work very closely with the product, there are things we can't recognize until we've got people beta testing the app. As we started Beta testing and conducting user-research, we realized that one aspect of the UI for the app was not intuitive to about half of our testers. We decided to make a few API changes to enable the mobile app to display a "linked" vs "unlinked" status in order to improve the user experience. Our front-end team is finalizing these changes, so our Beta testers will receive a new build in their testflight apps within the next few days. This new build will require another round of Beta testing to ensure that none of the code changes causes any problems on devices; if this change goes smoothly, and our mainnet testing goes smoothly, we will be able to release the app this month. Since there isn't much precedent on releasing a product into the app store that connects users with the ethereum mainnet, our primary concern is making sure the product works fully as intended and provides an intuitive user experience. Misc Q&A’s Q (elmer_FUD): What's your favorite thing to drink? A.1 (Andy): Overall, I really love Baja Blast Mountain Dew. If I am drinking, I'm a big fan of fruity beers like Blue Moon and Shocktop. Also had a really good raspberry sour recently A.2 (Nahom): Primary=water but i do enjoy Jamaican ginger ale/beer. We keep honest tea in the office too, i love it because it brings me back from the dead:skull_and_crossbones:, @Hydro Andy drinks most of it behind my back though :triumph: A.3 (Noah): hard: tequila or picklebacks soft: any sour beer other: mango juice i also crush like 2 nalgene’s worth of water every day at work A.4 (Shane): For hard alcohol: whiskey/bourbon A.5 (Anurag): ooh, went to the finback brewery last weekend; was wonderful — Q (Joleen): Do you HODL any other tokens personally? A.1 (Andy): I do. I think it is probably best to not say which, but if you follow me enough in #altcoins I am sure you will see me talk about a few A.2 (Noah): im a bit of an eth maximalist actually :grimacing: i do dabble though — Q (Joleen): Who got who in the World Cup sweepstakes? A.1 (Andy): I'm going for Germany, but I know next to nothing about soccer A.2 (Shane): I'm rooting for Portugal, but I don't think they're going to win the cup — Q (Joleen): Who's got the best banter in the office? And who has the worst? A.1 (Andy): One of our backend devs, Paavan, typically has some great banter and even better hot takes A.2 (Noah): dont @ me for worst banter A.3 (Shane): Sabih (BA @ Hydrogen) banter is by far the best
Hello! My name is Inna Halahuz, I am a sales manager at Platinum, the largest listing service provider for the STO and ICO projects. We know all about the best and most useful STO and ICO marketing services. By the way, we developed the best blockchain platform: [Platinum.fund] (https://platinum.fund/sto/) We also created the UBAI, the unique educational project with the best and most useful online courses. We not only share our knowledge but also help the best graduates to find a job! After finishing our courses you will know all about crypto securities, ICO and STO advertizing and best blockchain platforms. What a Blockchain Wallet is? What is its purpose? Find the answer after reading this article. Public/Private Key The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver. Accessing wallets Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals. Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets. Types of Wallets & Storage Methods The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners. Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens. Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples. Hardware wallets — LedgeTrezoAlternatives Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers. Paper Wallets Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper! Real World Historical Examples of Different Wallet Types Web Wallet: Blockchain.info Brief mechanism & Security Blockchain.info is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by blockchain.info has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops. Neon Wallet The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as https://bitcoinpaperwallet.com/ and https://walletgenerator.net/. They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible. Real World Example — Poor Practices MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets. In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes. Case Study: Good Practice Binance, the Attempted Hack During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “binance.com”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt. Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange. Hardware Wallets Advantages and Limitations We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations. Paper Wallets Advantages and Limitations Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever. Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose. You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait. How to Monitor Funds There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. Blockchain.info is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including nanoexplorer.io for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor. That’s not all!

4 Sub-$10 Million Market Cap Coins Worth Keeping An Eye On
1. Spectrecoin ($XSPEC) – $8.6 Million
What is Spectrecoin?
Utilizing a “range of proven cryptographic techniques” to achieve anonymous, untraceable, and un-linkable transactions, Spectrecoin is a secure Proof-of-Stake cryptocurrency enabling rapid P2P transactions and network privacy. Specifically, Spectrecoin is pulling out all the stops in order to protect user identity through their integration of:
Built-in Tor: Derived from the original software project moniker—The Onion Router—Spectrecoin is fully integrated with Tor, protecting real IP addresses at all times through the directing of traffic through a worldwide (and free) overlay network of more than 7,000 relays.
Anonymous coin creation: Deploying dual key stealth technology (a dual coin system), Spectre authorizes users to generate ‘anonymous coins’ known as SPECTRE for private and anonymous transactions as an alternative to their normal, everyday coin—XSPEC—for traditional transactions (most similar to Bitcoin).
Ring signatures: Through the execution and implementation of ring signatures, Spectrecoin user transaction history is wiped altogether, allowing users to exchange and transfer public coins, XSPEC, and SPECTRE.
At its core, Spectre’s dual coin system sanctions four fundamental types of privacy and anonymity transactions, XSPEC > XSPEC, XSPEC > SPECTRE, SPECTRE > SPECTRE, and SPECTRE > XSPEC, providing a plethora of transaction options for every type of user. And finally, if you’re looking for the TLDR (too long, didn’t read), Spectrecoin notes the best way to understand SPECTRE is to think of Bitcoin + Proof-of-Stake.v3 + anonymous transactions (similar to Monero) + Tor (for IP obfuscation).
Why You Should Keep an Eye On XSPEC
Unlike several other privacy coins which merely provide a Tor proxy—availing users to potential malicious exit nodes—Spectrecoin is fully integrated with Tor, a reliable and tested network providing one of the largest pools of IP addresses for confidentiality and untraceability. Coupled with staking, set at a 5% minimum per year, Spectrecoin offers a unique proposition (the only one in blockchain) for users looking to earn rewards while remaining anonymous by staking anonymous coins while generating more, fresh anonymous ones. Furthermore, for those looking for affirmation of Spectrecoin’s commitment to anonymity, not even the developers know each other’s real names—something that would have made walking away from a lacklustre ICO (which only raised 16 BTC at $600/700 per BTC) all too easy. Spectre has emphasized organic growth without an excessive and aggressive marketing push, opting instead for a working product and timely improvements to meet the ever-changing privacy arms race. And, with their funding gap set around £19,000, users can take solace in knowing the project isn’t an outright cash grab asking for millions to further tenuous goodwill—like far too many projects in the cryptosphere. At time of writing, XSPEC is listed on CoinMarketcap at US$0.41 or 5,970 Satoshis. Finally, if you’re wondering how Spectrecoin stacks up to other privacy coins, such as Monero, PIVX, and Zcash, check out this comparison chart.
2. FundRequest ($FND) – $1 Million
What is FundRequest?
In an age where open source software is an integral component for institutional, government, and nonprofit function and growth, there unfortunately remains a hindering factor—a cohesive, transparent, and styled request and transaction flow. Cue FundRequest, a decentralized marketplace for open source collaboration and catalyst for global open source sharing and circulation, empowering organizations, government, and other entities to:
Trustlessly transact via the blockchain and smart contracts to ensure all contracts created are self-resolving, tracked, and validated in a fair manner,
Incentivize organizations and developers to act in good faith through governance protocols and crypto economics,
Lower costsfor upkeep, while reducing friction for large-scale usage and adoption of open source technology,
Boost transparency for organizations looking to better understand average development and issue costs (ultimately resulting in a more efficient market), and
Integrate with third-party platforms (and vice versa), who are looking to benefit from already completed works.
Need to brush up on what exactly ‘open source’ means? The Open Source Initiative describes the concept of ‘open source’ as a tool which “enables a development method for software that harnesses the power of distributed peer review and transparency of process.” For example, a requesting organization (referred to as the funder) will allot set funds—stored in a smart contract (i.e., escrow)—in order to tackle an open source issue, which is then picked up and solved by a developer (the solver). In order to eliminate malicious behavior, FundRequest requires solvers to “have skin in the game,” by staking proportional valued funds, all released and claimed once the issue is solved. Simply put, FundRequest is the go-to facilitating and incentivization platform (similar to Airbnb and Uber) for funding, claiming, and rewarding open source commits and contributions, leading to an enriched and more collaborative open source ecosystem.
Why You Should Keep an Eye On FND
With an estimated US$60 billion-plus in savings per year for organizations and institutions, thanks to open-source software and technology adoption, FundRequest is set to act as the glue which connects all dispersed and integral parts and actors. Traditional software, prohibitive costs, and predatory vendor practices are proving not to be conducive towards maximal technological growth and development, as most people and organizations just simply can’t afford or maintain it. Plus, with a clear push by both private and public sectors to leverage community-based software for development and distribution over the last decade, it’s expanding at rapid pace. In 2018, it’s approximated over 50% of European and North American companies utilize open source software for “crucial applications,” along with over 50% of American government organizations. This is no small industry. GitHub alone boasts over 24 million users (more than 8 times their user base five years ago), and it’s estimated that in the EU and United States combined, there’s over 160 million persons working as freelancers and independent contractors in what’s known as the “gig economy.” And that’s just the tip of the iceberg, with over 60% of online gig economy workers accounted for in Asia. As of August 1st, FND’s price sits at right around US$0.03 or 472 Satoshis. Finally, for open source projects and ERC-20 token projects looking to increase development capacity, consider checking out FundRequest for potential partnerships. Already in their short tenure, FundRequest has partnered with:
Redefining convenience, simplicity, and compatibility, and short for the “Crypto One-Stop Solution’ exchange and platform, COSS is the native token and liquidity attraction tool of the Singapore-based exchange, boasting some of the most popular altcoins on the market while enabling users to receive weekly payouts in “dust” for all traded tokens. Specifically, COSS is looking to provide more than just a simple, fast, and secure cryptocurrency trading exchange—they’re building a borderless, digital economical system to bring cryptocurrencies to the masses via:
Digital wallet with integrated cash flow: allowing users to seamlessly transfer and store crypto funds between the exchange and wallet within a single application.
ICO platform: enabling projects to fund and their ICO on the COSS exchange to increase popularity, volume, and trading value.
Ultimately, COSS is looking to shake up the cryptocurrency exchange ecosystem through improved user experience, heightened product and feature functions, and a comprehensive foundation for employers, startups, companies, and traders to build towards a more accessible and mainstream cooperative blockchain community.
Why You Should Keep an Eye on COSS
With the rapid and gargantuan successes enjoyed by both Kucoin and Binance in 2018, crypto exchanges employing user-friendly token incentivization models are becoming a go-to for users looking to generate passive income while diversifying their crypto portfolio. However, unlike other cryptocurrency exchanges which have lowered their daily fee splits to nominal amounts, COSS has stayed true towards user rewards, keeping their daily percentage at 50%—paying out the respective dividends via a decentralized autonomous organization, ultimately guaranteeing an immutable percentage. In order to stay competitive in the present-day blockchain ecosystem, COSS’s whitepaper notes a minimum of 3-5 new features implemented per quarter. In the past several months, below are just several of their most notable achievements:
Partnership with Blockchain Terminal (BCT): Easing the transition for institutional investors to trade and transact on crypto exchanges.
NEO Listing: Trading pairs for NEO/BTC, NEO/ETH, NEO/USD, and NEO/COSS.
Preparation for COSS 2.0: The hiring of a team of over thirty developers in preparation of COSS 2.0, which is set to roll out dynamic withdrawal fees, sophisticated trading tools, dust conversion, public and private APIs, new wallet, institutional accounts, and more.
And, if you’re looking to know what COSS’s endgame here is, their goal is to shift completely towards a decentralized autonomous organization (DAO) in the future, where governance and decision making is outlined in code and run by a peer-to-peer network. Currently, COSS’s price is listed at US$0.06 or 935 Satoshis on Coinmarketcap. Finally, if you’re curious about COSS’s fee sharing, check out the COSS fee share calculator, which provides an accurate picture of your monthly exchange fee earnings relative to the amount of COSS owned. One Reddit user recently posted, and provided a screenshot, showing the COSS annual dividends to be at nearly 10% per year.
4. Lamden ($TAU) – $6.9 Million
What is Lamden?
Named after the Sherpa language word meaning “to guide,” Lamden is staying true to its name by easing the creation and deployment of dapps and custom blockchains. At its core, Lamden is providing a suite of developer tools mimicking “modern development processes in such tech stacks as Node.js or Python.” Simply put, Lamden is supplying the building blocks for experienced and amateur blockchain developers alike, enabling organizations and enterprise to skirt the energy and time costs of hiring and training expensive blockchain developers—ultimately speeding up efficiency and reducing overhead costs. Lamden is broken up into three fundamental sections, which all are in furtherance of project depth and the deployment of hyperfast blockchains for developers to not only experiment with, but test and deploy across other blockchain systems and platforms:
Saffron: a general tool sanctioning the deployment of private chains on an internal network, partitioning blockchains into individual use cases (e.g., an enterprise having their own web app), and bringing them together to interact when needed. Lamden CEO Stuart Farmer noted that from blockchain generation, to installment, all the way to deployment, an entire deployment cycle can be completed within a frame of just ten minutes!
Flora: a central repository for smart contract templates and packages, blockchain discovery tool, and private chain naming services, where developers are able to engage with one another, feed off one another’s innovations, and rapidly deploy and distribute smart contracts.
Clove: a payment network trustlessly facilitating communication between blockchain apps while handling payment channel swap processes, avoiding blockchain bloat and acting similarly to a telephone network.
Furthermore, Lamden supports the Ethereum network and Bitcoin-based blockchains at present, and boasts zero transaction fees and free chain-to-chain payments in exchange for chain allocation a specific amount of bandwidth for confirming payment channel transactions—meaning that its users are able to transact for free as a result of corporate entities bearing the network load and processing.
Why You Should Keep an Eye On TAU
Having released their ‘Cilantro’ testnet alpha in February 2018, Lamden has since hit the ground running, rolling out their first version of Clove soon after and tackling the necessary tune-ups and improvements in preparation of their mainnet launch in Q4 2018. Lamden’s mainnet is set to utilize a unique combination of Delegated Proof-of-Stake (DPoS) and the BFT Protocol, and will scale to process nearly 10,000 transactions per second. Moreover, in April 2018, Lamden announced the creation of LamDEX, their own decentralized cryptocurrency exchange and platform, where users will be able to stake their TAU—the native token of the Lamden platform—to act as a market maker, allowing for a cohesive back and forth across the TAU pair at prices faintly above and below market cost, ultimately generating rewards. With a rather daunting and tedious task ahead for anyone looking to utilize and incorporate existing smart contracts—which involves the manual searching for such on GitHub (a general repository website)—Lamden is truly adding value to blockchain and application development through their smart contract repository. Unlike GitHub, Lamden supports dependencies, versioning, and security, all essential elements for a quality package manager. Doing so adds not only convenience, but practicality to smart contract packages and implementation, and stands to save enterprise and organizations both exorbitant developer costs and time. If you’d like to learn more about Lamden’s developer tool suite, check out this complete overview from their blog. At the time of writing, Lamden’s price according to Coinmarketcap is US$0.04 or 699 Satoshis. To get a better picture of Lamden and their blockchain development tools ecosystem, check out this explanatory YouTube video from their channel. Final Thoughts Risk is inevitable when investing in crypto and blockchain projects. However, as long as you are cognizantly defining parameters for absorbing such risk, then diversifying your portfolio with smaller capped projects can be an effective way to realize value. Whether you’re looking for a user-friendly exchange to purchase crypto directly with fiat from (and earn dividends for loyalty) or wanting to execute anonymous and secure transactions with a P2P coin, the aforementioned projects are all bringing value to the crypto sphere through their overhaul of ineffective traditional mechanisms and institutions. Make sure to stay calm and collected during this bear market, associate yourself with quality projects that you think are bringing actual value to severely flawed industries, and remember, having a little gamble in you never hurts (as long as it’s properly accounted for).
