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

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.

Stakenet (XSN) - A DEX with interchain capabilities (BTC-ETH), Huge Potential [Full Writeup]
Preface Full disclosure here; I am heavily invested in this. I have picked up some real gems from here and was only in the position to buy so much of this because of you guys so I thought it was time to give back. I only invest in Utility Coins. These are coins that actually DO something, and provide new/build upon the crypto infrastructure to work towards the end goal that Bitcoin itself set out to achieve(financial independence from the fiat banking system). This way, I avoid 99% of the scams in crypto that are functionless vapourware, and if you only invest in things that have strong fundamentals in the long term you are much more likely to make money. Introduction
Stakenet is a Lightning Network-ready open-source platform for decentralized applications with its native cryptocurrency – XSN. It is powered by a Proof of Stake blockchain with trustless cold staking and Masternodes. Its use case is to provide a highly secure cross-chain infrastructure for these decentralized applications, where individuals can easily operate with any blockchain simply by using Stakenet and its native currency XSN.
Ok... but what does it actually do and solve? The moonshot here is the DEX (Decentralised Exchange) that they are building. This is a lightning-network DEX with interchain capabilities. That means you could trade BTC directly for ETH; securely, instantly, cheaply and privately. Right now, most crypto is traded to and from Centralised Exchanges like Binance. To buy and sell on these exchanges, you have to send your crypto wallets on that exchange. That means the exchanges have your private keys, and they have control over your funds. When you use a centralised exchange, you are no longer in control of your assets, and depend on the trustworthiness of middlemen. We have in the past of course seen infamous exit scams by centralised exchanges like Mt. Gox. The alternative? Decentralised Exchanges. DEX's have no central authority and most importantly, your private keys(your crypto) never leavesYOUR possession and are never in anyone else's possession. So you can trade peer-to-peer without any of the drawbacks of Centralised Exchanges. The problem is that this technology has not been perfected yet, and the DEX's that we have available to us now are not providing cheap, private, quick trading on a decentralised medium because of their technological inadequacies. Take Uniswap for example. This DEX accounts for over 60% of all DEX volume and facilitates trading of ERC-20 tokens, over the Ethereum blockchain. The problem? Because of the huge amount of transaction that are occurring over the Ethereum network, this has lead to congestion(too many transaction for the network to handle at one time) so the fees have increased dramatically. Another big problem? It's only for Ethereum. You cant for example, Buy LINK with BTC. You must use ETH. The solution? Layer 2 protocols. These are layers built ON TOP of existing blockchains, that are designed to solve the transaction and scaling difficulties that crypto as a whole is facing today(and ultimately stopping mass adoption) The developers at Stakenet have seen the big picture, and have decided to implement the lightning network(a layer 2 protocol) into its DEX from the ground up. This will facilitate the functionalities of a DEX without any of the drawbacks of the CEX's and the DEX's we have today. Heres someone much more qualified than me, Andreas Antonopoulos, to explain this https://streamable.com/kzpimj 'Once we have efficient, well designed DEX's on layer 2, there wont even be any DEX's on layer 1' Progress The Stakenet team were the first to envision this grand solution and have been working on it since its conception in June 2019. They have been making steady progress ever since and right now, the DEX is in an open beta stage where rigorous testing is constant by themselves and the public. For a project of this scale, stress testing is paramount. If the product were to launch with any bugs/errors that would result in the loss of a users funds, this would obviously be very damaging to Stakenet's reputation. So I believe that the developers conservative approach is wise. As of now the only pairs tradeable on the DEX are XSN/BTC and LTC/BTC. The DEX has only just launched as a public beta and is not in its full public release stage yet. As development moves forward more lightning network and atomic swap compatible coins will be added to the DEX, and of course, the team are hard at work on Raiden Integration - this will allow ETH and tokens on the Ethereum blockchain to be traded on the DEX between separate blockchains(instantly, cheaply, privately) This is where Stakenet enters top 50 territory on CMC if successful and is the true value here. Raiden Integration is well underway is being tested in a closed public group on Linux. The full public DEX with Raiden Integration is expected to release by the end of the year. Given the state of development so far and the rate of progress, this seems realistic. Tokenomics 2.6 Metrics overview (from whitepaper)
Ticker: XSN. Currency type: Coin.
Consensus: Minting Proof of Stake, Trustless Proof of Stake.
XSN is slightly inflationary, much like ETH as this is necessary for the economy to be adopted and work in the long term. There is however a deflationary mechanism in place - all trading fees on the DEX get converted to XSN and 10% of these fees are burned. This puts constant buying pressure on XSN and acts as a deflationary mechanism. XSN has inherent value because it makes up the infrastructure that the DEX will run off and as such Masternode operators and Stakers will see the fee's from the DEX. Conclusion We can clearly see that a layer 2 DEX is the future of crypto currency trading. It will facilitate secure, cheap, instant and private trading across all coins with lightning capabilities, thus solving the scaling and transaction issues that are holding back crypto today. I dont need to tell you the implications of this, and what it means for crypto as a whole. If Stakenet can launch a layer 2 DEX with Raiden Integration, It will become the primary DEX in terms of volume. Stakenet DEX will most likely be the first layer 2 DEX(first mover advantage) and its blockchain is the infrastructure that will host this DEX and subsequently receive it's trading fee's. It is not difficult to envision a time in the next year when Stakenet DEX is functional and hosting hundreds of millions of dollars worth of trading every single day. At $30 million market cap, I cant see any other potential investment right now with this much potential upside. This post has merely served as in introduction and a heads up for this project, there is MUCH more to cover like vortex liquidity, masternodes, TOR integration... for now, here is some additional reading.

11-05 20:58 - 'Is Bitcoin Safe and Legal?' (self.Bitcoin) by /u/koinalio removed from /r/Bitcoin within 2-12min
''' Buying, selling, or trading bitcoin is a private transaction in every part of the world. It is a lawful activity in most western and advanced countries, including the US, Canada, and the U.K. Some large economies have restrictions on Bitcoin, including China (ownership discouraged although not a criminal violation) and India ( banks banned from engaging in Bitcoin). Governments everywhere have concerns with the anonymous movement of funds; they wish to prevent the use of money for illegal purposes. Koinal understands the importance of anti-corruption laws and maintains legal standards for all sales and purchases. The best advice is to consult the laws of the country where one lives and intends to do business with Bitcoin. Koinal operates within the bounds of all applicable laws and meets legal requirements for transactions in every state in which it does business.
Is Bitcoin Safe?
The safety of Bitcoin also has some variables. Like all cryptocurrencies, there is no physical note or document. Owners must safely keep their digital currency and access codes because if lost or misused, there may be no recourse. An elaborate security system surrounds Bitcoin. The digital currency exists in a blockchain that cannot be altered by any government or central authority. Every Bitcoin transaction is transparent and watched by a global network. Unlike some other types of transactions, once the Bitcoin moves, there is no reversal mechanism. When you sell or buy, the transfer cannot be undone or canceled. Bitcoin is the oldest of the major currencies that include Ethereum, Lite, and Ripple. Bitcoin, by far, has the highest value, and many investors prefer Bitcoin for investment potential. Bitcoin is among the small group of cryptocurrencies that bring high levels of interest from mainstream financial companies and banks. Relative to other cryptocurrencies, Bitcoin enjoys a high level of interest. It is the most well-known cryptocurrency.
People can buy cryptocurrencies in many ways. The blockchain ledgers keep track of Bitcoin’s existence and ownership, and owners can transfer it on a peer-to-peer basis. Peer to peer transactions does not require any action by a government, bank, or any central authority. A safer and more widely used method is to perform transactions on Bitcoin exchanges. [Koinal works with Binance]1 and other leading currency exchanges. Koinal provides a simple and effective way to purchase Bitcoin using regular bank credit cards and debit cards.
Taxes and Virtual Currency
Bitcoin transactions can result in taxation when used to pay for goods, services, and wages. While it is not a recognized form of currency under U.S. tax law, it does have value. In some instances, the tax code assesses Bitcoin by its fair market value at the time of purchase. The U.S. government’s Internal Revenue Service has noticed Bitcoin and digital currency. It issued an advisory in 2014 and a new item on the tax return for 2020. The IRS named Bitcoin as one of many virtual currencies. The IRS advises that Bitcoin may represent income under tax laws and maybe a taxable asset when held as property. When treated as property under a national tax code, Bitcoin may get treated like other assets that grow in value, such as the U.S. capital gains tax. Investors, buyers, and sellers should consult legal and tax advisors for advice on their situations. At Koinal, we do not offer tax advice. We simply point out that each investor must examine the tax implications of Bitcoin or other virtual currency transactions.
Keeping Within the Law and Regulations
Koinal takes all required steps to keep its transactions within the bounds of national laws and regulations. Koinal requires identification and personal information needed to comply with anti-corruption and know-your-customer rules(KYC). Bitcoin transactions are not anonymous under current rules and regulations. Koinal offers a seamless purchasing experiencing for Bitcoin that can use a bank credit card or debit card. Our system provides quick and reliable delivery to the coordinates of your choice. Bitcoin offers exciting potential for usage as a currency, medium of exchange, and as an investment.

Kể từ khi Bitcoin xuất hiện vào năm 2009, nó đã trở thành cái mà mọi người nghĩ đến đầu tiên khi nhắc đến tiền điện tử hoặc blockchain. Các loại tiền điện tử như Bitcoin có tính biến động cao nhưng chúng dường như không biến mất trừ khi đánh sập toàn bộ hệ thống Internet trên thế giới. Ngày nay một Bitcoin có giá trị hàng nghìn đô la. Khi các loại tiền điện tử như Bitcoin tiếp tục tồn tại hoặc thậm chí tăng giá trị, các cá nhân rất có nhu cầu quan tâm đến việc sở hữu chúng nhưng điều quan trọng là họ muốn biết được cách lưu trữ Bitcoin một cách an toàn. Để đáp ứng nhu cầu của những người muốn đầu tư vào Bitcoin một cách an toàn, chúng tôi đã tập hợp một danh sách các thiết bị lưu trữ và hay còn gọi là các ví tiền ảo uy tín nhất. Có nhiều ví có tính năng rất tốt bao gồm khả năng lưu trữ nhiều loại tiền điện tử hơn mà không chỉ có Bitcoin, cũng như các biện pháp bảo mật bổ sung. Danh sách này không theo thứ tự cụ thể nào khác chỉ có đề cập đến ví nóng trước, nhưng điều đó không có nghĩa là ví nóng tốt hơn. Hiện tại, ví nóng được nhận xét là kém an toàn hơn để thực hiện các giao dịch nhanh chóng và ví lạnh là an toàn hơn để lưu trữ trong thời gian dài hơn. Trước hết chúng ta nên tìm hiểu về các khái niệm này trước khi chọn ví vì đó chính là chìa khóa để chọn được một phương tiện lưu trữ an toàn.
Các loại ví tiền ảo
Có 2 loại ví tiền ảo cơ bản đang được sử dụng trong thị trường lưu trữ tiền ảo.
Hot Wallets – Ví nóng
Ví trực tuyến còn được gọi là ví “nóng”. Ví nóng là ví chạy trên các thiết bị có kết nối internet như máy tính, điện thoại hoặc máy tính bảng. Điều này có thể tạo ra lỗ hổng bảo mật vì những ví này tạo ra khóa riêng cho tiền của bạn trên các thiết bị kết nối internet này. Mặc dù ví nóng có thể rất thuận tiện trong cách bạn có thể truy cập và thực hiện các giao dịch với tài sản của mình một cách nhanh chóng, nhưng chúng cũng thiếu bảo mật. Điều này nghe có vẻ xa vời, nhưng những người không sử dụng đủ bảo mật khi sử dụng các ví nóng này có thể bị đánh cắp tiền. Ví dụ: Khoe khoang trên một diễn đàn công khai như Reddit về số lượng Bitcoin bạn nắm giữ trong khi bạn đang sử dụng ít hoặc không có bảo mật cho ví của mình và lưu trữ nó trong một ví nóng sẽ không phải là điều khôn ngoan. Những ví này được sử dụng cho một lượng nhỏ tiền điện tử. Bạn có thể ví một ví nóng với một tài khoản séc. Sự khôn ngoan về tài chính thông thường cho rằng chỉ giữ tiền tiêu trong tài khoản séc trong khi phần lớn tiền của bạn nằm trong tài khoản tiết kiệm hoặc tài khoản đầu tư khác. Điều tương tự cũng có thể nói đối với ví nóng. Ví nóng bao gồm thiết bị di động, máy tính để bàn, web và hầu hết các ví lưu ký trao đổi. Điều quan trọng cần lưu ý ở đây là việc giữ tiền điện tử trong ví trao đổi không giống như giữ nó trong ví cá nhân của bạn. Ví trao đổi là tài khoản lưu ký do sàn giao dịch cung cấp. Người dùng của loại ví này không phải là người nắm giữ khóa cá nhân của tiền điện tử được giữ trong ví này. Nếu một sự kiện xảy ra khi sàn giao dịch bị tấn công hoặc tài khoản của bạn bị xâm phạm, tiền của bạn sẽ bị mất. Cụm từ “not your keys not your coin” là một khái niệm được lặp lại nhiều trong các diễn đàn tiền điện tử. Việc giữ một lượng lớn tiền điện tử trong bất kỳ ví nóng nào, đặc biệt là tài khoản trao đổi là không khôn ngoan. Mà thay vào đó, bạn nên rút phần lớn tiền về ví “lạnh” cá nhân của mình (giải thích bên dưới). Các “ví” trao đổi bao gồm Coinbase, Gemini, Binance và nhiều loại khác. Mặc dù các ví này được kết nối với Internet, có sự tấn công tiềm ẩn nhưng chúng vẫn rất hữu ích cho khả năng nhanh chóng thực hiện các giao dịch hoặc giao dịch tiền điện tử. https://preview.redd.it/ixb613gcljx51.png?width=800&format=png&auto=webp&s=38b14e9069a3f727908f38abc7f42b21dabbe7f8 Các loại ví tiền ảo
Cold Wallets – Ví lạnh
Loại ví tiếp theo sẽ được đề cập ở đây là ví lạnh. Mô tả đơn giản nhất về ví lạnh là ví không được kết nối với Internet và do đó nguy cơ bị xâm phạm thấp hơn nhiều. Những ví này cũng có thể được gọi là ví ngoại tuyến hoặc ví cứng. Các ví này lưu trữ địa chỉ và khóa cá nhân của người dùng trên một thứ không được kết nối với Internet và thường đi kèm với phần mềm hoạt động song song để người dùng có thể xem danh mục đầu tư của họ mà không gây rủi ro cho khóa cá nhân của họ. Có lẽ cách an toàn nhất để lưu trữ tiền điện tử ngoại tuyến là thông qua ví giấy. Ví giấy là một ví mà bạn có thể tạo ra từ một số trang web nhất định. Sau đó, nó tạo ra cả khóa công khai và khóa riêng tư mà bạn in ra trên một tờ giấy. Khả năng truy cập tiền điện tử trong các địa chỉ này chỉ có thể thực hiện được nếu bạn có mảnh giấy đó. Nhiều người cán mỏng những chiếc ví giấy này và cất chúng trong két an toàn tại ngân hàng hoặc thậm chí trong két sắt trong nhà. Ví giấy không có giao diện người dùng tương ứng ngoài một tờ giấy, vì vậy với mục đích của bài viết này, chúng tôi tập trung vào các phương pháp lưu trữ lạnh khác như ví cứng. Ví cứng thường là một thiết bị USB lưu trữ khóa cá nhân của người dùng một cách an toàn. Điều này có lợi thế hơn so với ví nóng vì nó không bị ảnh hưởng bởi vi-rút có thể có trong máy tính của một người vì khóa riêng không bao giờ tiếp xúc với máy tính được kết nối mạng của bạn hoặc phần mềm có khả năng bị tấn công. Các thiết bị này cũng thường là mã nguồn mở, cho phép cộng đồng xác định độ an toàn của nó thay vì một công ty tuyên bố rằng nó an toàn để sử dụng. Ví lạnh là cách an toàn nhất để lưu trữ Bitcoin hoặc các loại tiền điện tử khác của bạn. Tuy nhiên chúng yêu cầu thêm một chút kiến thức để thiết lập. Điều cần thiết đối với bất kỳ ai quan tâm đến việc sở hữu tiền điện tử là tìm hiểu về cách lưu trữ an toàn và các khái niệm về cả ví nóng và ví lạnh. Một khi bạn nghĩ rằng bạn đã sẵn sàng để tiếp tục tìm hiểu thì các ví được liệt kê dưới đây là một số ví tiền ảo uy tín nhất trong ngành mà chúng tôi đã sưu tầm được.
Exodus – Một trong các ví tiền ảo tốt nhất cho người mới bắt đầu
Loại ví: Ví nóng
Chi phí mua: Miễn phí
Tương thích với ví cứng: Trezor
Trao đổi hợp nhất: Có
Exodus là một ví điện thoại di động và máy tính để bàn có giao diện người dùng rất đơn giản và tích hợp sẵn một sàn giao dịch. Một trong những tính năng phổ biến nhất của Exodus là khả năng hoán đổi giữa một số lượng ngày càng tăng các loại tiền điện tử. Exodus hiện cho phép hoán đổi giữa hơn 100 loại tiền điện tử khác nhau. Với sự đơn giản của nó, ví này rất phù hợp cho những người mới bắt đầu tham gia vào ngành tiền điện tử. Nó cũng có sự hỗ trợ tuyệt vời, đây là một tính năng cần thiết cho những người mới bắt đầu tham gia vào cái mà nhiều người sẽ coi là một thị trường khó hiểu. Mặc dù nó rất tốt cho người mới bắt đầu, nhưng những người dùng cao cấp hơn có thể thấy nó thiếu một số tính năng. Đầu tiên, Exodus là một ví mã nguồn đóng. Điều này đi ngược lại đặc điểm của ý tưởng về Bitcoin và blockchain và có thể tạo ra một số lo ngại về bảo mật vì mã của nó không mở cho mọi người xem. Thay vào đó, người dùng dựa vào nhóm Exodus để đảm bảo không có lỗ hổng nào trong bảo mật ví của họ.Exodus có tùy chọn phí tùy chỉnh ngoài việc tự động đặt phí để đảm bảo giao dịch hoàn tất nhanh chóng. Ưu điểm
Nhiều loại tiền điện tử
Trao đổi tích hợp
Hỗ trợ khách hàng tốt

Electrum – Ví tiền ảo tốt nhất cho người dùng nâng cao quan tâm đến Bitcoin
Loại ví: Ví nóng
Chi phí mua: Miễn phí
Tương thích với ví cứng: thiết bị Trezor và Ledger
Trao đổi hợp nhất: Không
Electrum là một trong những ví Bitcoin ban đầu. Nó đã xuất hiện từ năm 2011, hai năm sau khi Bitcoin được tạo ra và đã thay đổi rất ít kể từ đó. Mặc dù ví này còn sơ khai về giao diện người dùng và cam kết chỉ dành cho Bitcoin, nhưng nó lại vượt trội ở chức năng chính này. Electrum cũng phù hợp hơn với người dùng cao cấp do các tùy chọn phức tạp của nó. Electrum sử dụng mã nguồn mở, cho phép người dùng đặt phí giao dịch tùy chỉnh và có tùy chọn để chọn giữa Bitcoin kế thừa và Segwit. Nó cũng cung cấp cho người dùng khả năng xác định mức độ bảo mật mà họ muốn sử dụng. Ví dụ: bạn có thể tạo ví tiêu chuẩn, ví có xác thực hai yếu tố hoặc ví đa chữ ký. Electrum là ví hoàn hảo cho người nắm giữ Bitcoin cao cấp hơn, những người muốn có các tính năng bảo mật tuyệt vời và khả năng tùy chỉnh trong một bố cục đơn giản. Ưu điểm
Khả năng đặt phí giao dịch tùy chỉnh
Mức độ bảo mật cao hơn hầu hết các ví nóng

Tương thích với ví cứng: thiết bị Trezor và Ledger
Trao đổi hợp nhất: Có
Mycelium là một ví Bitcoin có mã nguồn mở và chỉ dành cho thiết bị di động. Mycelium hiện chỉ hỗ trợ Bitcoin. Về mặt nào đó, Mycelium khá giống với ví Electrum với một số điểm khác biệt là nó chỉ dành cho thiết bị di động còn giao diện người dùng được làm mới hơn ví Electrum và cũng có một sàn tiền ảo tích hợp. Mycelium giống như Electrum là một trong những ví xuất hiện sớm hơn trong ngành tiền ảo. Cũng giống như Electrum, người dùng có thể đặt phí giao dịch tùy chỉnh để có thể chọn khoảng thời gian bạn sẵn sàng đợi giao dịch được hoàn thành. Mycelium cũng có một số tính năng thú vị hơn như hỗ trợ ví cứng, cho phép người dùng giữ Bitcoin của họ trong thiết bị lưu trữ ngoại tuyến trong khi vẫn sử dụng giao diện người dùng của Mycelium để xem tài sản của họ. Ưu điểm
Khả năng đặt phí giao dịch tùy chỉnh
Khả năng sử dụng ví phần cứng
Phần mềm mã nguồn mở
Chỉ sử dụng được trên điện thoại di động
Chỉ hoạt động với Bitcoin

Ledger Nano X – Ví cứng tốt nhất
Loại ví: Ví lạnh
Chi phí mua: $ 119
Trao đổi hợp nhất: Không
Ledger Nano X là ví cứng thế hệ thứ hai của Ledger, một công ty của Pháp đã tham gia vào ngành tiền điện tử trong vài năm. Sản phẩm đầu tiên của Ledger là Ledger Nano S, một trong những ví cứng đầu tiên trên thị trường và đã thống trị ngành tiền ảo trong một số năm. Nano X giống một chiếc USB và kết nối với thiết bị của bạn qua cổng USB hoặc Bluetooth. Điều này có nghĩa là bạn có thể kết nối ví với thiết bị iOS hoặc Android của mình và không cần máy tính. Nó hỗ trợ tốt hơn 1.500 loại tiền điện tử. Danh sách này tiếp tục tăng lên mỗi năm khi cộng đồng yêu cầu hỗ trợ cho các loại tiền điện tử yêu thích của họ. Mặc dù bản thân thiết bị là một chiếc ví cứng lưu trữ lạnh nhưng nhóm Ledger đã tạo ra phần mềm Ledger Live cung cấp giao diện người dùng cho tất cả tài sản của bạn. Điều này cung cấp cho người dùng khả năng thêm ví mới cho các loại tiền điện tử khác nhau vào thiết bị của họ và quản lý danh mục đầu tư của họ. Ví cứng Ledger đã và đang là ví phổ biến nhất trong ngành. Ledger cũng đi kèm với cáp USB Type-C để nó có thể được kết nối với máy tính để bàn hoặc điện thoại thông minh nếu không dùng được Bluetooth. Ưu điểm
Ledger Live có giao diện người dùng trực quan và tiện lợi
Có thể có tới 100 ứng dụng khác nhau được lưu trữ đồng thời
Phần mềm nguồn mở với lợi ích bổ sung là hỗ trợ khách hàng và cộng đồng
Sự thuận tiện khi kết nối Bluetooth
Một số người trong cộng đồng tiền điện tử tin rằng tích hợp Bluetooth là một phương thức tấn công tiềm ẩn, mặc dù có thể lựa chọn USB
Tính năng Bluetooth tăng thêm sự tiện lợi nhưng không mượt mà
Thiết bị Ledger chỉ cho phép bạn lưu trữ đồng thời một số lượng ví nhất định
Trezor Model T – Ví tiền ảo tốt nhất để lưu trữ một số lượng lớn tiền điện tử
Loại ví: Ví lạnh
Chi phí mua: $ 170
Trao đổi hợp nhất: Có
Trezor giống như Ledger, là một cái tên đồng nghĩa với lưu trữ ví lạnh tiền điện tử. Model T của nó là thế hệ thứ hai của ví cứng mà họ đã tạo ra. Trezor Model T rất giống với Ledger, nhưng nó cung cấp cho người dùng khả năng truy cập các sàn giao dịch của bên thứ ba như Changelly và Shapeshift, trực tiếp trong giao diện trang web của nó. Mặc dù điều này khá thuận tiện nhưng nó khó có thể biện minh cho mức giá đắt hơn 170 đô la của mình. Model T sử dụng màn hình cảm ứng, có thể dễ sử dụng cho người mới bắt đầu hơn so với các nút mà Model trước đã sử dụng. Trezor cũng có một khe cắm thẻ MicroSD, cho phép bạn sử dụng thẻ MicroSD để mã hóa mã PIN và bảo vệ thiết bị của bạn khỏi các cuộc tấn công. Giống như Ledger Nano X, Trezor Model T cũng đi kèm với cáp USB Type-C để bạn có thể kết nối với điện thoại thông minh hoặc máy tính để bàn của mình. Hiện tại, Trezor Model T hỗ trợ gần 1.400 loại tiền điện tử khác nhau. Một số người cho rằng Model T an toàn hơn một chút so với Ledger Nano X do kết nối Bluetooth. Điều đó nói rằng, người dùng Ledger có thể chỉ cần tránh sử dụng Bluetooth nếu họ muốn an toàn hơn. Ưu điểm
Giao diện người dùng dựa trên web với các trao đổi được tích hợp sẵn
Một danh sách khổng lồ các loại tiền điện tử được hỗ trợ
Phần mềm mã nguồn mở với lợi ích bổ sung là hỗ trợ khách hàng và cộng đồng
Không giới hạn số lượng ví bạn có thể có đồng thời
Mặc dù nó là một ví cứng tuyệt vời, nhưng giá của nó có vẻ hơi cao
Màn hình cảm ứng nhỏ có thể khiến bạn khó gõ
Ví cứng có thể gây nhầm lẫn cho người dùng lần đầu tiên
Ledger Nano S: Lựa chọntốt nhất cho túi tiền của bạn
Loại ví: Ví lạnh
Chi phí mua: $ 59
Trao đổi hợp nhất: Không
Ledger Nano S là thế hệ ví cứng đầu tiên được Ledger giới thiệu. Nó cũng là một trong những ví cứng đầu tiên từng được tạo ra. Nó tiếp nối ngay sau thế hệ đầu tiên của Trezor. Giống như người kế nhiệm, Nano S tương thích với hàng nghìn loại tiền điện tử. Nano S không đi kèm với cáp USB type-C, vì vậy người dùng sử dụng điện thoại thông minh hiện đại hơn có thể gặp khó khăn khi kết nối với thiết bị của họ. Nano S về cơ bản giống với người kế nhiệm của nó là Nano X ở chỗ nó hỗ trợ cùng một danh sách các loại tiền điện tử và có quyền truy cập vào phần mềm Ledger Live. Các tính năng mà nó thiếu là kết nối Bluetooth và bạn có thể có bao nhiêu ví đồng thời hoạt động trên thiết bị của mình. Với Nano X, người dùng có thể lưu trữ đồng thời 100 ví. Với Nano S, bạn chỉ có thể lưu trữ tối đa 18. Nano S chỉ có đủ dung lượng lưu trữ để tạo ví cho một số lượng tiền điện tử giới hạn tại một thời điểm. Nếu bạn xóa ví để thêm một loại tiền điện tử khác, bạn sẽ không mất tiền điện tử trong ví mà bạn đã xóa. Điều này là do tiền điện tử đó được lưu trữ trực tiếp trên blockchain. Ví đã xóa và tiền điện tử trong đó vẫn có thể được nhìn thấy trong Ledger Live, nhưng ví sẽ không được nhìn thấy trên chính thiết bị Ledger. Điều này có nghĩa là nếu bạn muốn gửi hoặc nhận từ ví bạn đã xóa, bạn có thể phải xóa ví khác để có thêm dung lượng. Điều đó nói rằng, Ledger Nano S vẫn là một chiếc ví tuyệt vời cho những người muốn lưu trữ tiền điện tử của họ một cách an toàn với một mức giá hợp lý. Nó cũng khá dễ sử dụng với Ledger Live, làm cho nó trở thành một sản phẩm lý tưởng cho người mới bắt đầu tìm kiếm cách lưu trữ an toàn và đơn giản cho một số ít tiền điện tử. Ưu điểm
Ledger Live có giao diện người dùng trực quan và tiện lợi
Lưu trữ tiền điện tử an toàn với mức giá thấp
Phần mềm mã nguồn mở với lợi ích bổ sung là hỗ trợ khách hàng và cộng đồng
Chỉ có thể lưu trữ tối đa 18 ví cùng một lúc
Nano S không có tính năng Bluetooth
Các ví tiền ảo ra đời nhằm đáp ứng nhu cầu lưu trữ an toàn các đồng tiền ảo. Vì vậy là một nhà đầu tư thông minh và có tầm nhìn bạn nên biết cách phối hợp để sử dụng các ví tiền ảo này một cách hiệu quả và tiết kiệm nhất. Không nhất thiết lúc nào cũng phải sử dụng ví lạnh và cũng không phải vì tiết kiệm mà chỉ chăm chăm sử dụng ví nóng. Điều quan trọng là không nên để hết trứng vào cùng một rổ, đó là kinh nghiệm lưu trữ và cất giữ tiền mà từ xưa ông cha ta đã chỉ dạy. Đối với tiền ảo cũng không ngoại lệ. Hy vọng bài viết về các ví tiền ảo uy tín trên đây sẽ giúp bạn đọc có thêm kiến thức và thông tin về việc lựa chọn và sử dụng ví tiền ảo.

Here is how to play the altcoin game - for newbies & champs
I have been here for many previous altcoin seasons (2013,2017 etc) and wanted to share knowedle. It's a LOOONG article. The evaluation of altcoins (i.e not Bitcoin) is one of the most difficult and profitable exercises. Here I will outline my methodology and thinking but we have to take some things as a given. The first is that the whole market is going up or down with forces that we can't predict or control. Bitcoin is correlated with economic environments, money supply increases, safe havens such as Gold, hype and country regulations. This is an impossible mix to analyze and almost everyone fails at it. That's why you see people valuing Bitcoin from $100 to $500k frequently. Although I am bullish on the prospects of Bitcoin and decentralization and smart contract platforms, this is not the game I will be describing. I am talking about a game where you try to maximize your BTC holdings by investing in altcoins. We win this game even if we are at a loss in fiat currency value. To put it another way:
If you are not bullish in general on cryptocurrencies you have no place in investing or trading cryptocurrencies since it's always a losing proposition to trade in bubbles, a scientifically proven fact. If on the other hand you are then your goal is to grow your portfolio more than you would if holding BTC/ETH for example.
Bitcoin is the big boy
How the market works is not easily identifiable if you haven't graduated from the 2017 crypto university. When there is a bull market everything seems amazingly profitable and things keep going up outgrowing Bitcoin by orders of magnitude and you are a genius. The problem with this is that it only works while Bitcoin is going up a little bit or trades sideways. When it decides to move big then altcoins lose value both on the way up and on the way down. The second part is obvious and proven since all altcoins from 2017 are at a fraction of their BTC value (usually in the range of 80% or more down). Also, when BTC is making a big move upwards everyone exits altcoins to ride the wave. It is possible that the altcoin market behaves as an inversed leveraged ETF with leakage where in a certain period while Bitcoin starts at 10k and ends at 10k for example, altcoins have lost a lot of value because of the above things happening.
We are doing it anyway champ!
OK so we understand the risks and just wanna gambol with our money right? I get it. Why do that? Because finding the ideal scenario and period can be extremely profitable. In 2017 several altcoins went up 40x more than BTC. But again, if you don't chose wisely many of them have gone back to zero (the author has first hand experience in this!), they have been delisted and nobody remembers them. The actual mentality to have is very important and resembles poker and other speculative games: A certain altcoin can go up in value indefinitely but can only lose it's starting investment. Think about it. You either lose 1 metric or gain many many more. Now that sounds amazing but firstly as we said we have the goal to outperform our benchmark (BTC) and secondly that going up in value a lot means that the probability is quite low. There is this notion of Expected Value (EV) that poker players apply in these kind of situations and it goes like that. If you think that a certain coin has a probability let's say 10% to go up 10X and 90% probability it goes to zero it's an even bet. If you think that probability is 11% then it's a good bet, a profitable bet and you should take it. You get the point right? It's not that it can only go 10X or 0X, there is a whole range of probability outcomes that are too mathematical to explain here and it doesn't help so much because nobody can do such analysis with altcoins. See below on how we can approximate it.
How to evaluate altcoins
A range of different things to take into account outlined below will form our decision making. Not a single one of them should dictate 100% of our strategy.
It's all about market cap. Repeat after me. The price of a coin doesn't mean anything. Say it 10 times until you believe it. I can't remember how many times I had conversations with people that were comparing coins using their coin price instead of their market cap. To make this easy to get.
If I decide because the sky is blue to make my coin supply 100 Trillion FoolCoins with a price of $0.001 and there is another WiseCoin with a supply of 100 Million and price of $1 then FoolCoins are more expensive. - Alex Fin's Cap Law
This is done usually in the stock world and it means that each company has some fundamental value that includes it's assets, customers, growth prospects, sector prospects and leadership competence but mostly centered in financial measures such as P/E ratios etc. Valuation is a proper economic discipline by itself taught in universities. OK, now throw everything out of the window!. This kind of analysis is impossible in vague concepts and innovations that are currently cryptocurrencies. Ethereum was frequently priced at the fictional price of gas when all financial systems on earth run on the platform after decades (a bit of exaggeration here). No project is currently profitable enough to justify a valuation multiple that is usually equal to P/E in the thousands or more. As such we need to take other things into account. What I do is included in the list below:
Check Github. You need to make sure there is active development for the platform and it's a very bad sign if the project is either keeping the code closed source or even worse there is simply no development. No projects are "complete".
Check Website. If the website is written in bad English the Chinese google translate type it means that they are not serious enough to produce an unbreakable decentralized project. If you can't write English you can't change the world, period. That's a deal breaker.
Check Team's Linkedin. Numerous projects have either fake Linkedin accounts or the team is comprised mainly by unexperienced employees that are even shown to be working in other companies currently.
Check backers. Projects that have Binance, Coinbase or Silicon Valley VC funds backing them are way more legit but way more overpriced too!
One of my favorite ways to value altcoins that is based on the same principle in the stock market is to look at peers and decide what is the maximum cap it can grow to. As an example you take a second layer Ethereum solution that has an ICO and you want to decide if you will enter or not. You can take a look at other coins that are in the same business and compare their market caps. Thinking that your coin will outperform by a lot the top coins currently is overly optimistic so I usually take a lower valuation as a target price. If the initial offering is directly implying a valuation that is more than that then there is no room to grow according to my analysis and I skip it. Many times this has proven me wrong because it's a game theory problem where if many people think irrationally in a market it becomes a self-fulfilling prophecy. But since there is opportunity cost involved, in the long run, getting in initial offerings that have a lot of room to grow will pay off as a strategy.
In 2017 the sexiest sector was platforms and then coins including privacy ones. Platforms are obviously still a highly rated sector because everything is being built on them, but privacy is not as hot as it used to be. In 2018 DEXes were all they hype but still people are massively using centralized exchanges. In 2020 Defi is the hottest sector and it includes platforms, oracles and Defi projects. What I am saying is that a project gets extra points if it's a Defi one in 2020 and minus points if it's a payment system that will conquer the world as it was in 2017 because that's old news. This is closely related to the next section.
Needless to say that the crypto market is a worse FOMO type of inexperienced trigger happy yolo investors , much worse than the Robinhood crowd that drove a bankrupt company's stock 1200% after they declared bankruptcy. The result is that there are numerous projects that are basically either vaporware or just so overhyped that their valuation has no connection to reality. Should we avoid those kind of projects? No and I will explain why. There are many very good technically projects that had zero hype potential due to incompetent marketing departments that made them tank. An example (without shilling because I sold out a while back) is Quantum Resistant Ledger. This project has amazing quantum resistant blockchain, the only one running now, has a platform that people can build tokens and messaging systems and other magnificent stuff. Just check how they fared up to now and you will get the point. A project *needs* to have a hype factor because you cannot judge it as normal stocks that you can do value investing like Warren Buffet does where a company will inevitable post sales and profitability numbers and investors will get dividends. Actually the last sentence is the most important: No dividends. Even projects that give you tokens or coins as dividends are not real dividends because if the coin tanks the value of the dividend tanks. This is NOT the case with company stocks where you get dollars even if the company stock tanks. All that being said, I would advice against betting on projects that have a lot of hype but little substance (but that should be obvious!).
How to construct your portfolio
My strategy and philosophy in investing is that risk should be proportional to investment capital. That means that if you are investing 100K in the crypto market your portfolio should be very different than someone investing 1K because 10% annual gains are nothing in the latter while they are very significant in the former. Starting from this principle each individual needs to construct a portfolio according to how much risk he wants to take. I will emphasize two important concepts that play well with what I said. In the first instance of a big portfolio you should concentrate on this mantra: "Diversification is the only free meal in finance". In the case of a small portfolio then this mantra is more important: "Concentrate to create wealth, diversify to maintain wealth". Usually in a big portfolio you would want to hold some big coins such as BTC and ETH to weather the ups and downs explained in previous paragraphs while generating profits and keep progressively smaller parts of your portfolio for riskier investments. Maybe 50% of this portfolio could be big caps and 10% very risky initial offerings. Adapting risk progressively to smaller portfolios makes sense but I think it would be irrational to keep more than 30% of a portfolio no matter what tied to one coin due to the very high risk of bankruptcy.
The altseason is supposedly coming every 3 months. Truth is that nobody can predict it but altcoins can be profitable no matter what. Forget about maximalists who are stuck in their dogmas. Altcoins deliver different value propositions and it makes sense because we are very far from a situation where some project offers everything like Amazon and we wouldn't even want that in the first place since we are talking about decentralization and not a winner takes all and becomes a monster kind of scenario! Some last minute advice:
Stay out of paid telegram/discord pump groups. They are deadly for your wallet.
Avoid jumping on overhyped coins that have pumped massively during the last days without any very important news.
Don't keep coins in obscure exchanges for too long or you will get burned with certainty.
Stop thinking that your coin will 1000x and overtake Bitcoin!
