"Hi Everyone in #Bitcoinsv , one of my last freelance jobs was to hook up SMS to a web form, and I can easily use this to send SMS from the Bitcoin API very cheaply, so you can text message real phones from Bitcoin. I need to set up opt-in list for this to be legal but will ASAP."
Is there a service that I could get a list of Merchant Addresses who accept Bitcoin? I'm gather info for Market Research so I can pitch to my employer why they need to support Bitcoin. I need to compare Businesses who we currently support who also take Bitcoin, would like to cross reference with Merchants in the same demographics to find a use case that I could show them as being a business need that my employer could fill.

To the awesome Dash community, A while back we implemented a Gold/DASH and Dash/Bitcoin pair on vaultoro.com. To help add liquidity, we recently added a negative trading fee for the DASH/BTC pair for people making that market. That means if you place an order in the order book and someone takes that order then you get paid 0.05%. I'm putting this post here to remind the community that we need help to make the market liquid. We are willing to pay the people to do that. Dash is one of our favourite projects and communities, hence the only other coin listed outside of bitcoin. Dash deserves liquid markets because we want people to feel comfortable buying and using it. For this reason, we have done everything we can to incentives people to add liquidity, and now we need your help to actualise it. There are great trading opportunities arbitraging with less liquid markets like ours as a market maker. Also, please let me know if you have any feedback. Our API is also live so if you have a bot let us know what bot you use so we can look at how to integrate. Best, Joshua Scigala CEO Vaultoro
I am very surprised that the entire cryptocurrency market bounced despite some VERY unfavorable news. I am even more surprised that DeFi specifically stood still during the storm of a minor Bitcoin sell-off. If you check the data from DeFi Pulse, you can see that the community locked $11.2 billion in assets before the dump and two days later it only dropped to $10.8 billion! https://i.ibb.co/cDhL8JX/where-to-yield-farm.png Yes, a majority of the DeFi tokens suffered extreme losses, some even dropped by 30%. We saw YFI, a leading token in the sector, losing $10k in price in only a few days. But you know what? We recovered. What brings even more confidence is the fact that while tokens suffered, the entire market structure stood stable. So everything is perfect now, right? Well, not really. If we continue to rise at the exponential rate the market rose in the past, we will have to deal with the same old problems. There are far too many to list but here are some of the most important ones:
Long transaction times
EXTREMELY high fees
Unstable and bad APY returns
If we take a look at any Ethereum statistics website we can see that most of these things are already fixed, for several weeks in fact. But if we remember how the market looked like when there was really high hype in the DeFi space, we remember how much of a nightmare it was. So now that it is the PERFECT time to yield farm, which platform should you choose? Well, I’m not going to hide anything, I’ll just reveal it right away. In July, I fell in love with a DEX after scouring Medium for new platform announcements that appeared like a good catch long-term. I discovered Anyswap, a cross-chain DEX that appeared to be relatively new to the space. However, I realized upon closer inspection that the devs and creators behind it have been in crypto for a far longer time than I could imagine. But I’ll leave this secret part for you to research since what Anyswap currently offers is even more important. Simply put, Anyswap is a DEX with yield farming capabilities that offers some of the best features possible. I have not yet encountered a project that surpasses what this DEX provides. First things first, gas fees are almost non-existent. Whether you want to do a token swap or be a liquidity provider, you will pay 1000x smaller fees compared to any other platform. Moreover, the reward structure is completely great. Even if the reward pools fall in APY, you still have another form of passive income that will keep you stable. With the ANY token, you have both governance control and rewards. Every ANY holder that participates in the liquidity pools earns 9900 ANY on average. As for the pools themselves, users earn around 927% APY on ANY pools and 159% on non-ANY pools. As for transaction times, that issue is fixed as well. Since Anyswap utilizes the Fusion network, a cross-chain finance ecosystem, transactions only take a few minutes no matter how much trading activity there is. To be honest, Anyswap did have its ups and downs when it launched. But guess what? That is true for literally any crypto and DeFi platform. Online for more than three months, I plan to still use Anyswap for yield farming so that I can earn high and secure rewards every day. And guess what? I’m still an early adopter, meaning that I will earn even more while Anyswap is still working silent in the market.
https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/22.214.171.124 Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that. Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap. We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout. Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now. Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date. The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use. There are so many goodies here it is hard to summarize them all. I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures. The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
Network magnitude unit pinned to a static value of 0.25
Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
500 GRC research reward limit for a CPID's first stake
6-month expiration for unclaimed rewards
10-block spacing requirement between research reward claims
Rolling 5-day payment-per-day limit
Legacy tolerances for floating-point error and time drift
The need to include a valid copy of a CPID's magnitude in a claim
10-block emission adjustment interval for the magnitude unit
One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
Verification codes of pending beacons expire after 3 days
Self-service beacon removal
Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
Rain addresses derived from beacon keys instead of a default wallet address
Beacon expiration determined as of the current block instead of the previous block
The ability for developers to remove beacons
The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
Beacons expire after 6 months pass (180 days)
Beacons can be renewed after 5 months pass (150 days)
Renewed beacons must be signed with the same key as the original beacon
Magnitudes less than 1 include two fractional places
Magnitudes greater than or equal to 1 but less than 10 include one fractional place
A valid superblock must match a scraper convergence
Superblock popularity election mechanics
Yes/no/abstain and single-choice response types (no user-facing support yet)
To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
Burn fee for creating polls scaled by the number of UTXOs claimed
50 GRC for a poll contract
0.001 GRC per claimed UTXO
Burn fee for casting votes scaled by the number of UTXOs claimed
0.01 GRC for a vote contract
0.01 GRC to claim magnitude
0.01 GRC per claimed address
0.001 GRC per claimed UTXO
Maximum length of a poll title: 80 characters
Maximum length of a poll question: 100 characters
Maximum length of a poll discussion website URL: 100 characters
Maximum number of poll choices: 20
Maximum length of a poll choice label: 100 characters
Magnitude, CPID count, and participant count poll weight types

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.

Nendly, the Notion-Friendly Forum is a social media site that offers a novel approach to Internet communities.
Social media today is a poor avenue for Internet conversations. Everyone can have their say, but only in their particular echochamber. While I've written more about it in an essay, go to cc and you'll see the main crux. The things you can talk about here won't fly so well there. Now why is that? It's because on Reddit, we have a downvote button. And since what you see is based on vote scores, it's essentially a censorship button. If you don't hold a 51% opinion, those in the majority will vote you down, and you'll leave to join another where the electorate is more favorable. And so we get a million insulated communities, each so sure that the others are wrong and needlessly hostile. But it doesn't have to be this way! Nendly uses a state-of-the-art voting algorithm that enables discussions wherein many competing ideas are possible. Instead of the upvote and downvote buttons being directly tied to what users see, Nendly performs viewpoint analysis to find the best content among a range of diverse beliefs. And since it uses game-theory, there's no possibility for an cc style take-over. You can read more about it here, but basically I've solved the cc problem, as seen in Nendly's much friendlier n/crypto community. Now there's a lot more to the site, including huge usability improvements and features Reddit doesn't have, but I'll have to leave it for a video I'll put out tomorrow. Ask me any questions and I'll address them then. (I need to sleep, it's been a wild day).
Ok but why is this a big deal for nano? The benefits are many.
Nano is exclusively integrated site-wide. Instead of Reddit "awards", we have nano-based gifts that mostly go to the end user. That's right, you can get paid to use social media. Forget Reddit's ETH integration, we've beet 'em to it, guys!
When someone awards your post or comment with nano, you get a helpful message from the system user, who gives you information about nano, the foundation, wallets, etc. so you can adopt it yourself.
The user base will be primarily non-crypto people, since I've intentionally built the site for a general-purpose audience. And since nano is the only crypto fully-integrated, we'll be actively getting people to join Nano. They won't just see it on a list with 50 other coins and bitcoin at the top. We are talking REAL ADOPTION.
With scale comes power. Imagine if we had complete control over the code for this subreddit. If someone had an idea requiring scale, we could actually fulfill it. We wouldn't have the "okay but where will you get your users" problem. If someone had an idea like ads that pay you nano to view them, we'd be able to break down that barrier. Well here's the thing, we've got Nendly, and with it we can solve the scale problem once and for all. Not just with n/crypto, but with the entire site if we like. As Nendly grows, so too does our launchpad.
There's more too for nano I'll put in the video. Again, ask me questions and I'll answer them when I'm not so tired :)
There's a lot of features that I'll be releasing over the coming days and weeks that are close to being done. For now, so I could meet the August deadline I set for myself, it's a Desktop-only experience with mobile coming very soon (we've also got a public API that's mostly done, PM me if you want to build an App or something). So hey, try my site out! You'll find updates coming out very fast since most of the cool stuff is ~90% done. I plan on a major update happening once a week, so it'll be a quick-moving experience if you join our community. Please bare with me since it's just now public. There's bound to be funny bugs we'll run into, and I already know some email providers are dropping my mail since they've never heard of nendly.com. And who knows, maybe the servers will explode. Also, I want to say thanks for all the support these past 2 months. I really wanted to give you something you could use before August ended, and thankfully we made it just hours before September! Edit ok, here’s the video!

vectorbt - blazingly fast backtesting and interactive data analysis for quants
I want to share with you a tool that I was continuously developing during the last couple of months. https://github.com/polakowo/vectorbt As a data scientist, when I first started flirting with quant trading, I quickly realized that there is a shortage of Python packages that can actually enable me to iterate over a long list of possible strategies and hyper-parameters quickly. Most open-source backtesting libraries are very evolved in terms of functionality, but simply lack speed. Questions like "Which strategy is better: X or Y?" require fast computation and transformation of data. This not only prolongs your lifecycle of designing strategies, but is dangerous after all: limited number of tests is similar to a tunnel vision - it prevents you from seeing the bigger picture and makes you dive into the market blindly. After trying tweaking pandas, multiprocessing, and even evaluating my strategies on a cluster with Spark, I finally found myself using Numba - a Python library that can compile slow Python code to be run at native machine code speed. And since there were no packages in the Python ecosystem that could even closely match the speed of my own backtests, I made vectorbt. vectorbt combines pandas, NumPy and Numba sauce to obtain orders-of-magnitude speedup over other libraries. It builds upon the idea that each instance of a trading strategy can be represented in a vectorized form, so multiple strategy instances can be packed into a single multi-dimensional array. In this form, they can processed in a highly efficient manner and compared easily. It also integrates Plotly and ipywidgets to display complex charts and dashboards akin to Tableau right in the Jupyter notebook. You can find basic examples and explanations in the documentation. Below is an example of doing in total 67,032 tests on three different timeframes of Bitcoin price history to explore how performance of a MACD strategy depends upon various combinations of fast, slow and signal windows:
import vectorbt as vbt import numpy as np import yfinance as yf from itertools import combinations, product # Fetch daily price of Bitcoin price = yf.Ticker("BTC-USD").history(period="max")['Close'] price = price.vbt.split_into_ranges(n=3) # Define hyper-parameter space # 49 fast x 49 slow x 19 signal fast_windows, slow_windows, signal_windows = vbt.indicators.create_param_combs( (product, (combinations, np.arange(2, 51, 1), 2), np.arange(2, 21, 1))) # Run MACD indicator macd_ind = vbt.MACD.from_params( price, fast_window=fast_windows, slow_window=slow_windows, signal_window=signal_windows, hide_params=['macd_ewm', 'signal_ewm'] ) # Long when MACD is above zero AND signal entries = macd_ind.macd_above(0) & macd_ind.macd_above(macd_ind.signal) # Short when MACD is below zero OR signal exits = macd_ind.macd_below(0) | macd_ind.macd_below(macd_ind.signal) # Build portfolio portfolio = vbt.Portfolio.from_signals( price.vbt.tile(len(fast_windows)), entries, exits, fees=0.001, freq='1D') # Draw all window combinations as a 3D volume fig = portfolio.total_return.vbt.volume( x_level='macd_fast_window', y_level='macd_slow_window', z_level='macd_signal_window', slider_level='range_start', template='plotly_dark', trace_kwargs=dict( colorscale='Viridis', colorbar=dict( title='Total return', tickformat='%' ) ) ) fig.show()
Analyze and engineer features for any time series data
Supercharge pandas and your favorite tools to run much faster
Test thousands of strategies, configurations, assets, and time ranges in one go
Test machine learning models
Build interactive charts/dashboards without leaving Jupyter
The current implementation has limitations though:
It's still experimental and fast evolving, thus API can change quickly.
Fast processing means more memory requirements. Above example created multiple DataFrames each taking 46MB of RAM (price, signals, cash, shares, equity, returns, etc). The issue can be mitigated by deleting at least some artifacts as soon as they are created and by disabling caching.
Usage requires intermediate knowledge of pandas and NumPy to understand what's going on. Numba can be learned faster because of it mimicking NumPy. I tried to make lots of small examples in the documentation to get the idea how everything is glued together.
The approach of merging vectorized and iterative code differs significantly from classic OOP approach of designing strategies, and will require you to rethink how strategies are formulated and implemented (which is kinda fun).
Finally, if you're looking for a pure backtesting solution - it's not. It's more of a data mining tool to get to know your market and approach better.
If it sounds cool enough, try it out! I would love if you'd give me some feedback and contribute to it at some point, as the codebase has grown very fast. Cheers.
Mainnet project: an important change. If you are a donor, please read.
Hi everybody. It has been one week since the mainnet project got the funding and I have an important update to make. A little bit about the progress: I've found a wonderful developer, who is helping with the library, so it is starting to take some shape. I'm ironing out our REST API, got some useful feedback, continuing to do so. About 0.17% of the total funding spent so far. The important update though is that I have decided to take the development and spending private, instead of public. Before I explain what that means and why, I understand that it might upset some donors. So, if you have pledged any amount and disagree with my change for any reason - please contact me (DM, or [email protected]) and I'll refund your pledge completely, no questions asked. (Please sign any message using the address that you used to prove that you sent the funds, see the list of donors here to find your pledge and the link the the funding donation to find which address you sent from). If more than 50% of pledges ask for money back, I'll just return everything to everybody in full and we'll consider the project cancelled. At that point anyone willing to take on the project (via a new Flipstarter or something), I'll donate the domain to them. Everything that is done so far is MIT licensed, so anyone is free to take it at any moment. Let the market decide! I've got to tell you that I'm a bit disappointed with our progress so far. I expected a lot of people willing to earn some money, but I've got only 4 relevant developers, 3 of them passed a very simple test, only one is actually doing anything. This was not expected by me, when I had promised to work publicly and with BCH developers. Another problem is that I have a certain vision that I described in the project description. In addition to that vision there is also a lot of experience talking to read.cash users. A lot of them are in countries with very bad Internet (2G, few kilobytes per second), using very old Android phones (10+ years, the size of an iPhone 4 and the speed half of that of iPhone 4).. And I also really hope that someday we will have 100MB blocks, 1GB, 1TB blocks. But now I'm tied in arguments with BCH developers who argue that many current solutions are good enough already and we don't need to change them - just build on top of a few convoluted and complex protocols, just download a block when needed (again, Africa, 2G, 100MB blocks), just download 640,000 block headers, listen to the whole mempool (with 1TB block we'll have 1TB mempool) - it's fine, blocks are tiny... Just send a few queries (now)... Just download a mempool fully. (To those of you that know what this is about, please don't name names, I'm not here to play the blame game, everybody is entitled to their own opinions. It's fine.) If your wallet becomes too big - create a new one. It's fine.
Sidenote: my read.cash wallet that gets the fees takes a few hours to open now, and it's barely 9 months old! I find current solutions unacceptable, I want my wallet to open up immediately and handle 100MB blocks as well as 60KB blocks.
I don't want to develop for tiny blocks or tiny wallets that need to be changed every few months.. I want huge blocks! I don't want mainnet to be as brittle as to break at the first sight of success. A few of these discussions got me really tired and I have no leverage on these guys. They have money now, they have their vision, I have mine, described on the site, they don't want to do it my way. I didn't collect the funds to do it their way. Yet I have made a commitment to work with them. This is very tiresome. I feel like I've got myself into a trap - I have to work with these people, they don't want to work on my stuff. This is just stupid. One more thing is that now that I have Slack - I'm caught in endless private discussions of people trying to sell me their vision of how stuff should be done or questions about me or read.cash... I didn't sign up for that, I barely have any time to do the work, I don't have time for this, sorry. Change #1: Private development Having said that, I'm moving the project to private development. Frankly, all I care about is to get this project done. I added an additional burden on myself to be do the public development. And it's tiresome. The plan would be to hire some outside developers, using regular contracts, so that they don't have THEIR ideas on how to do the project and they'll just do what I described. I think everybody cares about the end result - library working, document being written, etc... Change #2: Private spending Hired developers also means salaries. When people (in the real world) know salaries of other people, it leads to conflicts. I went through this experiment (public salaries) once in my life, I won't go through that again. Even people knowing your budget become a problem, since they start to bargain with you. (Again, we're talking about outside developers, they are not interested in BCH success, they are interested in getting as much money as possible) By private spending I mean that I'll post periodically how much is done and how much funds is approximately left, but no details on who got what for what. Right now there's 99.83% funds left. Some of you might see it as a money grab or something else - I can't blame you, but I'd rather see this project cancelled by market forces than drown in endless fights about why we should do exactly nothing or their idea, hope for small blocks and use what we have no matter how convoluted or hard it is, or why somebody's hourly rate should be bigger than that guy's. Will this lead to everyone cancelling their donations? It sure could! It's voluntary funding after all, I can't force anyone to love what I do or how I do it. If you donated and want a refund to your original address - just ping me. When this post is 48 hours old, if more than 50% pledges remain, the project will move on as described above. If 50%+ cancels - everybody gets refunds to their original addresses.
UniLend has deep connections with the Ankr team that go back before the start of the UniLend project, so we are excited to continue this mutually beneficial partnership. Like all true decentralized projects UniLend will also need powerful and secure nodes from different geographic locations to help bolster our platform. We are pleased to have such a strong ally at our backs helping to run one of our nodes via their robust and direct Ethereum API access. Ankr has established a reputation for creating gateways to Web 3.0 by connecting consumers, developers and enterprises to the new internet in a few easy clicks. It is well known that Ankr already supports 30+ nodes for many prominent networks like Bitcoin, Ethereum and Binance so we know we are in good hands. Our new partner Ankr is not only known for running robust nodes: they also produce developer API’s, and Enterprise solutions. To Unlocking the Future for Many Our project is supporting and offering comprehensive functionality for a vast range of digital assets like permissionless listing of any ERC20 asset, trading, lending and borrowing. Also, our native token UFT will allow for complete decentralized governance. As our project continues to grow, so will our partnership with Ankr and their services. We raise a toast to truly unlocking the future of decentralized finance together!

If you're quite technically-minded, the Zano whitepaper gives a thorough overview of Zano's design and its main features. So, what is Zano? In brief, Zano is a project started by the original developers of CryptoNote. Coins with market caps totalling well over a billion dollars (Monero, Haven, Loki and countless others) run upon the codebase they created. Zano is a continuation of their efforts to create the "perfect money", and brings a wealth of enhancements to their original CryptoNote code. Development happens at a lightning pace, as the Github activity shows, but Zano is still very much a work-in-progress. Let's cut right to it: Here's why you should pay attention to Zano over the next 12-18 months. Quoting from a recent update:
Anton Sokolov has recently joined the Zano team. ... For the last months Anton has been working on theoretical work dedicated to log-size ring signatures. These signatures theoretically allows for a logarithmic relationship between the number of decoys and the size/performance of transactions. This means that we can set mixins at a level from up to 1000, keeping the reasonable size and processing speed of transactions. This will take Zano’s privacy to a whole new level, and we believe this technology will turn out to be groundbreaking!
If successful, this scheme will make Zano the most private, powerful and performant CryptoNote implementation on the planet. Bar none. A quantum leap in privacy with a minimal increase in resource usage. And if there's one team capable of pulling it off, it's this one.
What else makes Zano special?
You mean aside from having "the Godfather of CryptoNote" as the project lead? ;) Actually, the calibre of the developers/researchers at Zano probably is the project's single greatest strength. Drawing on years of experience, they've made careful design choices, optimizing performance with an asynchronous core architecture, and flexibility and extensibility with a modular code structure. This means that the developers are able to build and iterate fast, refining features and adding new ones at a rate that makes bigger and better-funded teams look sluggish at best. Zano also has some unique features that set it apart from similar projects: Privacy Firstly, if you're familiar with CryptoNote you won't be surprised that Zano transactions are private. The perfect money is fungible, and therefore must be untraceable. Bitcoin, for the most part, does little to hide your transaction data from unscrupulous observers. With Zano, privacy is the default. The untraceability and unlinkability of Zano transactions come from its use of ring signatures and stealth addresses. What this means is that no outside observer is able to tell if two transactions were sent to the same address, and for each transaction there is a set of possible senders that make it impossible to determine who the real sender is. Hybrid PoW-PoS consensus mechanism Zano achieves an optimal level of security by utilizing both Proof of Work and Proof of Stake for consensus. By combining the two systems, it mitigates their individual vulnerabilities (see 51% attack and "nothing at stake" problem). For an attack on Zano to have even a remote chance of success the attacker would have to obtain not only a majority of hashing power, but also a majority of the coins involved in staking. The system and its design considerations are discussed at length in the whitepaper. Aliases Here's a stealth address: ZxDdULdxC7NRFYhCGdxkcTZoEGQoqvbZqcDHj5a7Gad8Y8wZKAGZZmVCUf9AvSPNMK68L8r8JfAfxP4z1GcFQVCS2Jb9wVzoe. I have a hard enough time remembering my phone number. Fortunately, Zano has an alias system that lets you register an address to a human-readable name. (@orsonj if you want to anonymously buy me a coffee) Multisig Multisignature (multisig) refers to requiring multiple keys to authorize a Zano transaction. It has a number of applications, such as dividing up responsibility for a single Zano wallet among multiple parties, or creating backups where loss of a single seed doesn't lead to loss of the wallet. Multisig and escrow are key components of the planned Decentralized Marketplace (see below), so consideration was given to each of them from the design stages. Thus Zano's multisig, rather than being tagged on at the wallet-level as an afterthought, is part of its its core architecture being incorporated at the protocol level. This base-layer integration means months won't be spent in the future on complicated refactoring efforts in order to integrate multisig into a codebase that wasn't designed for it. Plus, it makes it far easier for third-party developers to include multisig (implemented correctly) in any Zano wallets and applications they create in the future. (Double Deposit MAD) Escrow With Zano's escrow service you can create fully customizable p2p contracts that are designed to, once signed by participants, enforce adherence to their conditions in such a way that no trusted third-party escrow agent is required. https://preview.redd.it/jp4oghyhv9q51.png?width=1762&format=png&auto=webp&s=12a1e76f76f902ed328886283050e416db3838a5 The Particl project, aside from a couple of minor differences, uses an escrow scheme that works the same way, so I've borrowed the term they coined ("Double Deposit MAD Escrow") as I think it describes the scheme perfectly. The system requires participants to make additional deposits, which they will forfeit if there is any attempt to act in a way that breaches the terms of the contract. Full details can be found in the Escrow section of the whitepaper. The usefulness of multisig and the escrow system may not seem obvious at first, but as mentioned before they'll form the backbone of Zano's Decentralized Marketplace service (described in the next section).
What does the future hold for Zano?
The planned upgrade to Zano's privacy, mentioned at the start, is obviously one of the most exciting things the team is working on, but it's not the only thing. Zano Roadmap Decentralized Marketplace From the beginning, the Zano team's goal has been to create the perfect money. And money can't just be some vehicle for speculative investment, money must be used. To that end, the team have created a set of tools to make it as simple as possible for Zano to be integrated into eCommerce platforms. Zano's API’s and plugins are easy to use, allowing even those with very little coding experience to use them in their E-commerce-related ventures. The culmination of this effort will be a full Decentralized Anonymous Marketplace built on top of the Zano blockchain. Rather than being accessed via the wallet, it will act more as a service - Marketplace as a Service (MAAS) - for anyone who wishes to use it. The inclusion of a simple "snippet" of code into a website is all that's needed to become part a global decentralized, trustless and private E-commerce network. Atomic Swaps Just as Zano's marketplace will allow you to transact without needing to trust your counterparty, atomic swaps will let you to easily convert between Zano and other cyryptocurrencies without having to trust a third-party service such as a centralized exchange. On top of that, it will also lead to the way to Zano's inclusion in the many decentralized exchange (DEX) services that have emerged in recent years.
Where can I buy Zano?
Zano's currently listed on the following exchanges: https://coinmarketcap.com/currencies/zano/markets/ It goes without saying, neither I nor the Zano team work for any of the exchanges or can vouch for their reliability. Use at your own risk and never leave coins on a centralized exchange for longer than necessary. Your keys, your coins! If you have any old graphics cards lying around(both AMD & NVIDIA), then Zano is also mineable through its unique ProgPowZ algorithm. Here's a guide on how to get started. Once you have some Zano, you can safely store it in one of the desktop or mobile wallets (available for all major platforms).
How can I support Zano?
Zano has no marketing department, which is why this post has been written by some guy and not the "Chief Growth Engineer @ Zano Enterprises". The hard part is already done: there's a team of world class developers and researchers gathered here. But, at least at the current prices, the team's funds are enough to cover the cost of development and little more. So the job of publicizing the project falls to the community. If you have any experience in community building/growth hacking at another cryptocurrency or open source project, or if you're a Zano holder who would like to ensure the project's long-term success by helping to spread the word, then send me a pm. We need to get organized. Researchers and developers are also very welcome. Working at the cutting edge of mathematics and cryptography means Zano provides challenging and rewarding work for anyone in those fields. Please contact the project's Community Manager u/Jed_T if you're interested in joining the team. Social Links: Twitter Discord Server Telegram Group Medium blog I'll do my best to keep this post accurate and up to date. Message me please with any suggested improvements and leave any questions you have below. Welcome to the Zano community and the new decentralizedprivateeconomy!
