Bitcoin Price Prediction with Neural Networks
Ethereum Classic is an open, decentralized, and permissionless public blockchain, that aims to fulfill the original promise of Ethereum, as a platform where smart contracts are free from third-party interference. ETC prioritizes trust-minimization, network security, and integrity. All network upgrades are non-contentious with the aim to fix critical issues or to add value with newly proposed features; never to create new tokens, or to bail out flawed smart contracts and their interest groups.
For Watson, I have found this article that shows how to discover from a set of features, which are the ones that most influence the outcome. https://www.ibm.com/communities/analytics/watson-analytics-blog/predicting-with-watson-analytics-a-quick-start-guide/ But can IBM Watson give me a prediction curve? For example imagine I want to predict the bitcoin price. I have 10 fields as input (date, time, weather, air pressure, whatever etc.) and one output (bitcoin price). Using that tutorial I now know that I can manually ask Watson to show me which inputs are most relevant for the bitcoin price. But can I ask him to forecast the output now? For Amazon, is there an API for these operations? To train Amazon NN, to ask him the important fields and the prediction model, and to ask him or the model to predict the future? Thanks!
What are bitcoins really? I'm having a hard time explaining to a friend.
I send my friend the explanation in Mastering Bitcoin --- but it was still too complex. What is the easiest way to convey that bitcoins are not digital coins but locked value on the network? I am not sure I even fully understand it myself.

Discussion can relate to the technology itself or economics. Talk about community and price is not wanted, but some discussion about it maybe allowed if it relates well. Be as respectful and nice as possible. This discussion has potential to be more emotionally charged as it may bring up issues that are extremely upsetting: many people are not only financially but emotionally invested in the ideas and tools around Monero. It's better to keep it calm then to stir the pot, so don't talk down to people, insult them for spelling/grammar, personal insults, etc. This should only be calm rational discussion about the technical and economic aspects of Monero.

I have written this guide to dispel a common misconception I hear from this community - that putting more than one Graphics Card in your Bitcoin Farm is a great idea. TLDR: The FIRST graphics card you put in your bitcoin farm generates a bitcoin every 20 hours. Every additional graphics card you put in your bitcoin farm generates a bitcoin every 333.33 hours. This information is misstated on the wiki and in many videos I've seen. More Complicated Maths TLDR from u/Mekhazzio : TLDR: The bitcoin farm has a base production rate that's much higher than the rate added by each additional graphics cards. So when investing, you shouldn't be looking at how fast the whole farm pays itself off, but how much time it takes your N>1 graphics cards to each pay for themselves, because otherwise you could have just been pocketing the pure profit from the base production rate the whole time. At current therapist/flea-FiR values:
Baseline Rubles/Hr 7732.45
per-GPU Rubles/Hr 473.42
GPU days to payoff 22
That is to say, adding a GPU to an already-running farm takes three weeks before you've stopped losing money on that GPU. A pretty simple formula is utilized to determine Bitcoin Farming output. The payback period for your first graphics card is around 3 days. For each additional graphics card that you put in the payback period is over 20 days. The reason that this has confused so many people is that they credit the production from Graphics Card 1 to the payback period for the rest of the Graphics Cards. Caveat 1: Escape from Tarkov is a video game and, at least for us players, not a business. Many video game players are completionists, and I will not begrudge anyone who wants to max out every single part of their hideout because it will feel like an achievement. This guide discusses the impact of bitcoin farming on your PMC's wallet. If you find utility in maxing out the bitcoin farm for the feeling of completion then you should do it and probably just close this guide and not worry about it. Caveat 2: This guide will not address people who hatchet run or pistol run to put graphics cards in their secure container that will usually end up being non-FIR. There are too many variables (spawn rate, survival rate, replacement value of just doing normal Tarkov raids instead of hatchet runs) to do a decent analysis. If you end up with non-FIR graphics cards you should put them in your Bitcoin Farm. Analysis: The formula for bitcoin generation is as follows:
Let's simplify some unnecessary constants and make this look more like a normal mathematical function. All we have to do is multiply (1/49) * (0.15) to get this, which is equivalent and much easier to understand:
Building the empty bitcoin generator: ~300k roubles
Graphics Card Cost: ~250k roubles
Bitcoin sale price to Therapist: ~150k roubles
Caveat 3: Prices may change, blah blah blah, unless the IRL bitcoin market crashes the conclusions from this guide will still be accurate for the most part. I will also note that I'm not going to include the cost for fuel needed for production. Because you can craft expeditionary fuel into mag boxes, as well as do other crafts on your workbench and med station while you have the power on, this cost is negligible. Furthermore, since my thesis is that putting more graphics cards in is not worth it, the fact is that I can prove this mathematically without even accounting for the entire cost category of fuel only strengthens my argument. Using these assumed prices, let's take a look at some different cases. Case 1: Building a Bitcoin Generator and putting a single graphics card in. To calculate cost, we add the cost of building the empty generator (300k) to the single graphics card (250k) to get 550k rouble investment. Lets calculate revenue using our formula before:BTC Generated per Hour = 0.05 + 0.003 * (Graphics Cards - 1)BTC Generated per Hour = 0.05 + 0.003 * (1 Graphics Cards - 1)BTC Generated per Hour = 0.05 + 0.003 * (0)BTC Generated per Hour = 0.05 So we're generating 5% of a bitcoin every hour which means we'll get a bitcoin from our farm every 20 hours. So, every 20 hours we are generating a product worth ~150k. Since we invested ~550k we need to sell: 550k investment / 150k roubles per bitcoin = 3.66 physical bitcoins in order to recoup our investment Since we can't harvest bitcoins until they are full, we actually need to wait until we get 4 bitcoins at which point we'll be making a slight profit. Generating 4 bitcoins will take 4 bitcoins * 20 hours per bitcoin = 80 hours or a little more than 3 days. Case 2: Adding a second graphics card to our bitcoin farm. Now, as discussed above I'm not worried about non-FIR graphics cards that you hatchet ran to find. If you have an FIR graphics card then you can sell it on the flea market for the 250k price that I'm using as an assumption above. This concept is called opportunity cost and if you don't understand it I will troll you in the comments: Putting an FIR graphics card into your bitcoin farm is the same as purchasing one off of the flea market and putting it in your bitcoin farm because you had the opportunity to just sell your FIR graphics card for the same price that you can buy it. With that out of the way, let's do some math on our 2 graphics card bitcoin farm: BTC Generated per Hour = 0.05 + 0.003 * (Graphics Cards - 1)BTC Generated per Hour = 0.05 + 0.003 * (2 Graphics Cards - 1)BTC Generated per Hour = 0.05 + 0.003 * 1BTC Generated per Hour = 0.053 So, for the cost of 250k roubles we have increased our bitcoin per hour generation by 0.003. The first graphics card that we added to our bitcoin farm generates us one bitcoin every 20 hours, as discussed above. The second graphics card that we added to our bitcoin farm generates 0.003 bitcoins per hour. To calculate how many hours this takes to get 1 bitcoin we do the math of 1 / 0.003 = 333.33 hours. 333.33 hours / 24 hours per day is 13.88 or roughly 14 days. In order to recoup our investment from the 250k roubles we used to get our second graphics card we divide 250k roubles invested by 150k roubles per bitcoin = 1.66 bitcoins. We generate one bitcoin every 14 days, so we can multiply 14 days * 1.66 bitcoins = 23 days. This math will hold true for every additional graphics card because the function is linear. Thus, the payback period for your 250k investment in adding a graphics card past the first one to your bitcoin farm is 23 days. To reiterate: The FIRST graphics card you put in your bitcoin farm generates a bitcoin every 20 hours. Every additional graphics card you put in your bitcoin farm generates a bitcoin every 333.33 hours.
Ledger Live adds Coin control: Here's why that matters.
Ledger Live version 2.11.1 (download link) adds Coin control for power users. The coin control feature gives advanced users more granular control over their wallets. It enables them to change how and which coins are selected when making transactions. This increases their ability to manage their privacy and the network fees they will have to pay to spend their account balance. More control over your coins
How does it work?
The account balance for Bitcoin and its derivatives consists of all the unspent transaction outputs (UTXOs) in the account. You can think of UTXOs as the coins in a regular wallet. When you receive money, you collect coins in your wallet. Then, when you want to make a payment, you get to choose which coins you pick from your wallet. Do you pick the largest coins first? Or do you want to spend all the smaller value coins to lighten up your wallet? Similar considerations can be made when creating a Bitcoin or Bitcoin derivative (altcoin) transaction. Before the Coin Control feature was released, all transactions involving Bitcoin (and altcoins) automatically selected their coins using the First-In-First-Out (FIFO) algorithm. This strategy includes the oldest coin in the account, and when the amount is not sufficient the second-oldest coin is added, and so forth. As of Ledger Live version 2.11.1, users are able to make use of a dedicated Coin Control tool to choose the coin selection strategy and the coins that may be spent.
Click on Send, choose an account to debit, and enter a recipient address. Click on Continue.
Enter an amount and click on Advanced options. You will then see: - The currently selected, default coin selection strategy: Oldest coins first (FIFO). - A toggle to enable Replace-By-Fee (RBF). - A toggle to include coins from unconfirmed, replaceable transactions.
Click on Coin control. The coin control modal opens.
Select a Coin selection strategy from the dropdown menu: - Oldest coins first (FIFO). This is the default strategy that spends the oldest coins first. - Minimize fees (optimize size). This strategy tries to minimize the byte size of the transaction by spending the lowest number of UTXOs. This results in a low network fee. - Minimize future fees (merge coins), This strategy includes the maximum number of inputs so that a potential future price rise does not make smaller UTXOs economically unspendable. If the price of a crypto asset increases too much, small UTXOs may become worth less than the cost of the network fees to spend them.
Select which coins may not be included in the selection by unticking their checkbox. The SELECTED indicator shows which coins will be included in the transaction. By changing the selection strategy and/or coins to include, the user has precise control over which coins end up being spent. The Coins to spend and Change to return indicators show how much is spent from and returned to the account.
Click on Done to return to the Send flow to verify and send the transaction.
The following statuses can be displayed for a coin:
Coins received in a transaction with 0 confirmations without RBF enabled: PENDING
Coins received in a transaction with 0 confirmations with RBF enabled: REPLACEABLE
Coins received in a transaction with 1337 confirmations: 1337 CONFIRMATIONS
By enabling the toggle Include coins from unconfirmed, replaceable transactions, replaceable transactions can be selected in the Coin control screen.
The Privacy use case
One of the main use cases for Coin control is to protect one’s privacy. UTXOs are, unfortunately, not perfectly fungible due to their unique history on the blockchain. Therefore, users may want to spend coins from different sources without mixing them together, because this would indicate to an outside observer of the blockchain that these addresses belong to the same account. For instance, if one were to spend coins bought on a KYC exchange, which are associated with the user’s identity, together with coins bought anonymously using cash, the anonymous coins could be linked to the user’s identity. Another example would be that you would like to prevent spending a high-value coin for smaller purchases because this would unnecessarily show the person you’re paying how much you have. This is similar to not showing the boulanger how much is on your bank account when buying a baguette.
Let us know what you think!
We are excited to release this new feature because we think it will fulfill real needs of an important part of our users. This version of Ledger Live marks an important milestone, but we will continue working on more features that our community wants. So, we invite you to try out Coin control in Ledger Live and let us know what you think! All feedback is welcome on this thread, on ledgerwallet, and you can send suggestions or get help through our official contact form. We'd like to close out by underlining our commitment to the Bitcoin community, and our willingness to build the best wallet ecosystem for newbies as well as for power users.
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...

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.

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/ Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners? And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess. First, let's consider some principles of Bitcoin.
You the HODLer should be the one who controls where your money goes. Your keys, your coins.
You the HODLer should be able to coordinate and make contracts with other people regarding your funds.
You the HODLer should be able to do the above without anyone watching over your shoulder and judging you.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so). So, how does Taproot affect those principles?
Taproot and Your /Coins
Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash). (technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input). However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits! Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh? With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save! And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well! (P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1) Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service! So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win! (even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot) And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!
Taproot and Your Contracts
No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade. So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust. Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade. However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade. In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address. Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants). But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer). Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos). (technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).
Taproot and Your Contracts, Part 2: Cryptographic Boogaloo
Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code. This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded. And you can do that, with HTLCs, today. Of course, HTLCs do have problems:
Privacy. Everyone scraping the Bitcoin blockchain can see any HTLCs, and preimages used to claim them.
This can be mitigated by using offchain techniques so HTLCs are never published onchain in the happy case. Lightning would probably in practice be the easiest way to do this offchain. Of course, there are practical limits to what you can pay on Lightning. If you are buying something expensive, then Lightning might not be practical. For example, the "software" you are activating is really the firmware of a car, and what you are buying is not the software really but the car itself (with the activation of the car firmware being equivalent to getting the car keys).
Even offchain techniques need an onchain escape hatch in case of unresponsiveness! This means that, if something bad happens during payment, the HTLC might end up being published onchain anyway, revealing the fact that some special contract occurred.
And an HTLC that is claimed with a preimage onchain will also publicly reveal the preimage onchain. If that preimage is really the activation key of a software than it can now be pirated. If that preimage is really the activation key for your newly-bought cryptographic car --- well, not your keys, not your car!
Trust requirement. You are trusting the developer that it gives you the hash of an actual valid activation key, without any way to validate that the activation key hidden by the hash is actually valid.
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar". Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you. Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige). (Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key). So:
Privacy: PTLCs are private even if done onchain. Nobody else can learn what the private key behind the public key is, except you who knows the adaptor signature that when combined with the complete onchain signature lets you know what the private key of the activation key is. Somebody scraping the blockchain will not learn the same information even if all PTLCs are done onchain!
Lightning is still useful for reducing onchain use, and will also get PTLCs soon after Taproot is activated, but even if something bad happens and a PTLC has to go onchain, it doesn't reveal anything!
Trust issues can be proven more easily with a public-private keypair than with a hash-preimage pair.
For example, the developer of the software you are buying could provide a signature signing a message saying "unlock access to the full version for 1 day". You can check if feeding this message and signature to the program will indeed unlock full-version access for 1 day. Then you can check if the signature is valid for the purported pubkey whose private key you will pay for. If so, you can now believe that getting the private key (by paying for it in a PTLC) would let you generate any number of "unlock access to the full version for 1 day" message+signatures, which is equivalent to getting full access to the software indefinitely.
For the car, the manufacturer can show that signing a message "start the engine" and feeding the signature to the car's fimrware will indeed start the engine, and maybe even let you have a small test drive. You can then check if the signature is valid for the purported pubkey whose privkey you will pay for. If so, you can now believe that gaining knowledge of the privkey will let you start the car engine at any time you want.
(pedantry: the signatures need to be unique else they could be replayed, this can be done with a challenge-response sequence for the car, where the car gathers entropy somehow (it's a car, it probably has a bunch of sensors nowadays so it can get entropy for free) and uses the gathered entropy to challenge you to sign a random number and only start if you are able to sign the random number; for the software, it could record previous signatures somewhere in the developer's cloud server and refuse to run if you try to replay a previously-seen signature.)
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script. (technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)
Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable?? Well, in theory yes. In practice, they probably are not. It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash. When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key. So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key. (public keys should be public, that's why they're called public keys, LOL) And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions. So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort. Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers. For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
Current quantum computers can barely crack prime factorization problem for primes of 5 bits.
The 256-bit elliptic curve use by Bitcoin is, by my (possibly wrong) understanding, equivalent to 4096-bit primes, so you can see a pretty big gap between now (5 bit primes) and what is needed (4096 bit primes).
A lot of financial non-Bitcoin systems use the equivalent of 3072-bit primes or less, and are probably easier targets to crack than the equivalent-to-4096-bit-primes Bitcoin.
Quantum computers capable of cracking Bitcoin are still far off.
Pay-to-public-key-hash is not as protective as you might think.
We will probably see banks get cracked before Bitcoin, so the banking system is a useful canary-in-a-coal-mine to see whether we should panic about being quantum vulnerable.
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).
If you are a singlesig HODL-only Bitcoin user, Taproot will not affect you positively or negatively. Importantly: Taproot does no harm!
If you use or intend to use multisig, Taproot will be a positive for you.
If you transact onchain regularly using typical P2PKH/P2WPKH addresses, you get a minor reduction in feerates since multisig users will likely switch to Taproot to get smaller tx sizes, freeing up blockspace for yours.
If you are using multiparticipant setups for special systems of trade, Taproot will be a positive for you.
Remember: Lightning channels are multipartiicpiant setups for special systems of lightning-fast offchain trades!
I Wanna Be The Taprooter!
So, do you want to help activate Taproot? Here's what you, mister sovereign Bitcoin HODLer, can do!
If you have developer experience especially in C, C++, or related languages
Review the Taproot code! There is one pull request in Bitcoin Core, and one in libsecp256k1. I deliberately am not putting links here, to avoid brigades of nontechnical but enthusiastic people leaving pointless reviews, but if you are qualified you know how to find them!
But I am not a cryptographeBitcoin Core contributomathematician/someone as awesome as Pieter Wuille
That's perfectly fine! The cryptographers have been over the code already and agree the math is right and the implementation is right. What is wanted is the dreary dreary dreary software engineering: are the comments comprehensive and understandable? no misspellings in the comments? variable names understandable? reasonable function naming convention? misleading coding style? off-by-one errors in loops? conditions not covered by tests? accidental mixups of variables with the same types? missing frees? read-before-init? better test coverage of suspicious-looking code? missing or mismatching header guards? portability issues? consistent coding style? you know, stuff any coder with a few years of experience in coding anything might be able to catch. With enough eyes all bugs are shallow!
If you are running a mining pool/mining operation/exchange/custodial service/SPV server
Be prepared to upgrade!
One of the typical issues with upgrading software is that subtle incompatibilities with your current custom programs tend to arise, disrupting operations and potentially losing income due to downtime. If so, consider moving to the two-node setup suggested by gmax, which is in the last section of my previous post. With this, you have an up-to-date "public" node and a fixed-version "private" node, with the public node protecting the private node from any invalid chainsplits or invalid transactions. Moving to this setup from a typical one-node setup should be smooth and should not disrupt operations (too much).
If you are running your own fullnode for fun or for your own wallet
Be prepared to upgrade! The more nodes validating the new rules (even if you are a non-mining node!), the safer every softfork will be!
If you are using an SPV wallet or custodial wallet/service (including hardware wallets using the software of the wallet provider)
Contact your wallet provider / SPV server and ask for a statement on whether they support Taproot, and whether they are prepared to upgrade for Taproot! Make it known to them that Taproot is something you want!
But I Hate Taproot!!
Raise your objections to Taproot now, or forever hold your peace! Maybe you can raise them here and some of the devs (probably nullc, he goes everywhere, even in rbtc!) might be able to see your objections! Or if your objections are very technical, head over to the appropriate pull request and object away!
Maybe you simply misunderstand something, and we can clarify it here!
Or maybe you do have a good objection, and we can make Taproot better by finding a solution for it!
xBTC had its 1st rebase and it was a massive 25.32%!!!
xBTC is a revolution in rebasing, we actually argue that we have found what rebasing was made for, the "killer app" for rebasing. On chain tokenized derivatives. xBTC rebases to reward holders when Bitcoin Dominance goes down. xBTC shares three traits with derivatives. xBTC: 1) insures against market movements; 2) increases market exposure; 3) allows access to otherwise hard to trade assets. The notional value of all derivatives is $640T - the real value is $12T. Robinhood made 63% of their revenue from options trading (a derivative).

Axion - A Global Currency, Built To Serve The People
What is Axion? Per Axion's website:
AXION is the answer to our global financial markets that are on the brink of disaster. The original solution to this impending collapse was Bitcoin, a decentralized peer-to-peer currency. However, since its inception, certain aspects of Bitcoin, such as lack of speed and high fees, have shifted Bitcoin into more of a store-of-value than a currency. Axion is the currency to address that. With a high-interest time-locked savings account, Participants in the Axion Network are rewarded daily.
Rewards people, not the corporate elite
Global & Scalable
How is AXION distributed?
Anyone holding Hex2T (pre-sale) tokens will receive AXION at a rate of 1:1
Hex holders will also receive AXION 1:1, limited at 10M AXION tokens. Hex holders will also be auto-locked for a year, with 2% releasing weekly. More details can be found in the whitepaper. If Hex holders do not claim their AXION tokens, they will become available for purchase in the Daily Auction every week.
The Daily Auction
Putting Tokens and Value into your pocket.
To get Axion, it needs to be claimed by Hex & Hex2T holders, the longer they wait to claim, the more penalties they face. About 2% of their total per week. This 2% is added into a daily auction pool where people can bid using ETH on the Axion tokens within it. If you bid 10% of the ETH on that day, you get 10% of the pool rewards. 80% of the ETH paid in the auction is then used to hyperdrive both the Axion token and the stakers earnings. First, the ETH is used to purchase the tokens, boosting the token price, and then those tokens are distributed to stakers, creating a very strong positive feedback loop.
Axion is on the path to becoming the ideal global currency.
For the first time in history, inflation is increasing the purchasing power of the people within the network. Axion has partnerships lined up to be integrated in online and in-person payment solutions, where you can pay for nearly everything in your every-day life using Axion. The merchants can accept FIAT (converted from Axion), or Axion itself. This is a global movement.
Axion: Built to Scale
500 Billion Initial Total Supply 1:1 Freeclaim ratio for Hex2T and Hex holders 80% of ETH Earned in auctions is used to buy back tokens 8% Annual inflation that goes Directly to stakers 100% of all purchased tokens Are distributed to stakers No Auto-Stake For hex2t holders 100% autostake for hex holders
How to buy:
**Video Tutorials:**Metamask Install – https://www.youtube.com/watch?v=htyEeKNHX5ABuy/Sell Axion (HEX2T) – https://www.youtube.com/watch?v=vYZBOkHIM5k How Do I Buy Axion (HEX2T)? Step One: Purchase Ethereum from your exchange of choice (Coinbase, Binance, etc). You can also purchase Ethereum through Metamask and have it sent directly to your Metamask wallet (More details on this in Step Three). If buying through Coinbase, you’ll have the option to use a linked bank account or a debit card. Funds purchased via linked bank account will have a hold period while the bank transaction clears, funds purchased via debit card will be available for use instantly. Step Two: Install the Metamask desktop browser extension and set up your Ethereum Wallet. You may also install the Metamask app on your Android smartphone and follow the same set up process in the linked video. (Apologies iOS users, the iOS Metamask app has restrictions that disable necessary features, you’ll have to use the desktop browser extension) Step Three: Once you have your Metamask wallet set up and your seed words properly saved, it’s time to deposit Ethereum to your wallet. – If you’ve purchased Ethereum on an exchange such as Coinbase or Binance, you’ll have to copy your wallet address from Metamask and withdraw the Ethereum from the exchange to your Metamask wallet address that you just copied. Be sure to check the wallet address multiple times before sending as transactions can not be reversed. – If you’d like to purchase Ethereum directly through Metamask, you can do so using the Wyre fiat gateway that is integrated into Metamask. Step Four: Now that you have Ethereum in your Metamask wallet, you can head over to our listing on the Uniswap Exchange to purchase Axion (HEX2T). We recommend using Fast GAS to speed up your transactions. You may also have to click on the gear icon in the top right on Uniswap to adjust your slippage limit when buying larger amounts. – If using the Metamask app on Android, you’ll have to access the in-app browser through the menu (three bars top left of app) and paste the provided link. – You will see a “From” input that should have ETH as the selected currency pointing to a “To (estimated)” output that should have HEX2T as the selected currency. The “From” input is the amount of Ethereum you will be spending and the “To (estimated)” output is the amount of HEX2T that you will receive for that amount of Ethereum. – Once you enter the amount of Ethereum you’d like to spend, the button at the bottom of the page should say “Approve”. This “Approve” function allows the exchange to access Ethereum in your wallet, which is necessary to complete this transaction. You’ll click the “Approve” button and the exchange will send a transaction to your wallet, which you will have to confirm. Wait for that Approve transaction to clear and once it does the button should change from “Approve” to “Swap”. – Now that you’ve given the exchange permission to use the Ethereum in your wallet, you can click the “Swap” button. This will send another transaction to your wallet that you’ll have to confirm. Once that transaction clears, you’ll have successfully purchased HEX2T with Ethereum! Side Note: If you can’t see the HEX2T that you’ve purchased in your Metamask wallet’s Asset list, you’ll have to add the token to your Asset list. At the bottom of the Asset list you will see an “Add Token” button, click on that and you’ll see a “Search” and a “Custom Token” tab. Click on the “Custom Token” tab and paste the following address (0xed1199093b1abd07a368dd1c0cdc77d8517ba2a0) into the “Custom Token Address” field, the rest of the info should auto-fill. Then click the “Next” button in the bottom right, and it should display your HEX2T balance, click the “Add Tokens” button and you should now see your HEX2T in your Asset list. **How Do I Sell Axion (HEX2T)?**To sell Axion (HEX2T), you essentially do the inverse of what you did to purchase it.Step One: Head over to Uniswap Exchange and click on ETH in the “From” input, a drop down list will appear and you’ll select HEX2T. In the “To (estimated)” output, click on “Select a Token” and select ETH. To clarify, if you want to sell, HEX2T should be on top, ETH should be on bottom. Step Two: Enter the amount of HEX2T you’d like to sell in the “From” input, the button at the bottom of the page should say “Approve”. This “Approve” function allows the exchange to access HEX2T in your wallet, which is necessary to complete this transaction. You’ll click the “Approve” button and the exchange will send a transaction to your wallet, which you will have to confirm. Wait for that Approve transaction to clear and once it does the button should change from “Approve” to “Swap”. – Now that you’ve given the exchange permission to use the HEX2T in your wallet, you can click the “Swap” button. This will send another transaction to your wallet that you’ll have to confirm. Once that transaction clears, you’ll have successfully sold HEX2T for Ethereum!

True Bitcoin ownership goes by a simple name in our world. Well at least if you believe in the mantra of not your keys, not your coins. It's simply referred to as the UTXO Set. The UTXO Set is the full list of the Transaction Outputs on the entire Bitcoin blockchain. These are basically how many addresses have bitcoin associated with them. Anyone running their own node can see how many UTXOs exist at anytime by looking at the UTXO Set. Here's the incredible part: there's only 68 million UTXOs. 68 million! That means there are only a maximum of 68 million people who control the keys their bitcoin in a world of 7.5 billion! But of course we know the real amount is much lower than that when considering most exchanges have thousands if not millions of UTXOs, all the lost bitcoins, HD wallets etc. We absolutely must prioritize the removal of our coins from all exchanges as quickly as possible. These exchanges have been invested in heavily by the banks years ago and they have their tentacles in as deep as possible and have been manipulating the USD price of bitcoin for years. They do so using other methods that have controlled other hard asset prices for decades. These manipulation tactics combine rehypothification, commingling, cash settled futures, OTC markets, along with coordinating the denial of access to exchanges when they start to lose control of the process momentarily. Look, the banks are the competition to bitcoin. They run the world by creation of dollars which we all currently (directly or in directly) depend on as it is the world reserve currency. Every day we sell our labor and skills for dollars that they directly control the production and value of them. Meanwhile we live in a world where they have brainwashed people to believe that inflation by devaluing the currencies we sell ourselves for is a good thing! Thank God we now have a viable exit strategy with bitcoin! However the only way for the majority to pry the power away from the legacy financial system is to decide that we want to determine what the value of our time is rather than let them make us work longer and harder every year for less purchasing power. And we can! Well that is if we accept that supply and demand truly determines value, then we must hold our Bitcoin keys individually for it to be valued for what it truly is - the world's first truly finite asset with properties that are superior to all previous SOVs before it and one that can be carried around in your brain! This can absolutely be our peaceful revolution! One that would create a more just and civilized world for everyone. But in order to get there we have to collectively understand these few key concepts and must absolutely take the our keys out of the bankers hands! Spread the word and let the true peaceful revolution that is bitcoin truly begin to occupy Wall St!
Instead of honest democracy or free-market meritocracy, we truly live under rule by parasites. (This term is not meant to be derogatory but to be apt. I suppose many, if not most of us, would opt to be one of the parasites, if given the choice.) Trying to describe how the financial and political elites receive unearned wealth and power can get complicated very quickly. To find a simple but rigorous theory to cover most major features of the beast requires looking at it the right way. By and large, how it works is that:
The elites use state power to prop up the values of money, debt, and other financial assets artificially, to benefit those who issue them, i.e. themselves. When some over-valued asset eventually must crash, the entire economy suffers the loss of jobs, business and savings.
Example: The Bank Account Public illusion. A commercial-bank 'deposit' is as good as money. You will get all your money back, any time you want. Reality. 'Deposits' are really loans to the bank which lends them to borrowers, some of whom may never pay them back. Another danger is that savers may ask for their money at any time, while loans by the bank tend to have longer-term maturities. How to bridge myth and reality. An truly free-market system would drive banks to communicate expectations openly. A simple example could be having 'depositors' expect to lose money if the bank makes bad loans. The problem with such an honest system, of course, is that top politicians and bankers wouldn't benefit much, since people would likely put much less money in banks. The confidence trick. The government props up the illusion, while it can. Classic tools over the centuries include allowing banks to collude by rescuing each other in a crisis, bailing banks out with public money, and providing deposit insurance. If this gives bankers the incentives to take too much risk, bankers redeem themselves by being a lender to the government. Since both sets of elites benefit, what problem is there? (In recent decades investment banks and money market funds have formed a shadow banking system which plays an equivalent role. While the last US commercial-bank bust happened in the 1980s' savings-and-loan crisis, the last shadow-bank variety occurred in 2007-8.) Analysis. While credit is indeed crucial to economic growth, to use government power to prop up the values of loans to banks, and then to rely on bureaucrats and their rules to limit risk-taking by bankers is a distortion of the credit market. It is the driver of much human misery. Central planning, somehow, always benefits the few at the expense of the many, even if it claims to do just the opposite.
Example: Government Bonds Public illusion. The 'full faith and credit' of the government stands behind the IOU it issues to you. Your IOU is as good as money. Reality. Since much public debt is almost as trusted as money, incurring this debt is almost as good as printing money. Politicians thus have an incentive to maximize the issuance of debt to receive free political capital, even if this destabilizes their own system in the long run. Public debt all over the world goes only up. Even though powerful governments can keep their debt bubbles going for a century or more, those incentives mean that their IOUs will eventually lose value, one way or another. How to bridge myth and reality. Even aside from the moral problems of 'money' creation and putting burden on people who can't yet vote, public debt should at least be allowed to sink or swim in the capital markets. If a government incurs too much debt, savers would be incentivized to punish it by demanding a higher yield, and politicians would in turn be incentivized to cut back borrowing. The confidence trick. When savers get too wary of public debt, the central bank steps in to buy it with freshly printed money, thus propping up the value of these IOUs. This is done in the name of 'monetary policy,' either by buying public debt directly as 'open market' operations, or, more frequently, by supplying banks with cheap new money so they will buy it. Most of the time, savers can't fight city hall, and will thus tend to buy and hold IOUs, further limiting the downside risk of their values. This entire system thus amounts to a bubble. Analysis. It doesn't matter how powerful a government is -- Public debt always crashes eventually. The dominant global empires of Spain, the Netherlands, and Britain were destroyed by this crash in their days. (In the case of Britain the relevant 'public debt' took the form of paper pound sterling that was officially an IOU for a fixed amount of gold.) No one believes US debt is really payable with anything close to the purchasing power savers and foreign central banks used to buy it, although by the time its value can no longer be propped up, most politicians and voters who have benefited from issuing it will have been gone.
Example: Money Public illusion. Central banks issue and destroy currency to manage economic output for the benefit of the public. At least in the West, proper management has resulted in low and constant inflation that has justified the public's evident trust in currency's value. Reality. The real job description of the central bank is to safeguard the state-bank alliance. It holds power over the most central asset, money, in order to discourage both politicians and bankers from issuing assets too fast and thus endangering the system. The goal is well-paced harvesting of the fruits of real work. Over the decades, prices only move in one direction: up. How to bridge myth and reality. Unfortunately, there is no way to remove the incentives to abuse the issuance of money while the state or a banking cartel has any role in the issuance. The confidence trick. The problem of holding up the public's trust in currency was solved in a simple fashion by the classical gold and silver standards in their day, while the authorities had enough precious metals to back their paper. Today, the central bank needs to keep the return on 'safe' assets (e.g. short-term Treasuries, insured deposits) above the return on non-state-issued assets, i.e. gold, silver and Bitcoin. (Recent books like 'Gold Wars' and 'The Gold Cartel' have come up with good evidence of central-bank suppression of precious metal prices by trading derivatives.) In this it seems to succeed most of the time, but fail spectacularly at other times. It also needs to keep the return on 'safe' assets below the return on risky assets like stocks, over the long term. The goal of both operations is to use state power to force savers to take risks and help prop up the bubble economy. (Ever wonder why financial crisis always seems to come back?) When you hear of 'tightening' or 'loosening' the money supply, this control is what's really going on. So, it's not that the public trusts currency; most feel they have no choice. Analysis. It's not, as most mainstream economists claim, that state-controlled money is required for modern economic growth. The Italian Renaissance and Scottish 'free-banking' era were counter-examples. It's really the other way round. The real productivity of the modern world gives value to the financial assets issued by the elites, and thus help sustain their financial inflation, at least until the perverse incentives destabilizes the system anyway. In the Middle Ages, money was physical gold and silver -- when there was no wealth to extract, the state couldn't create its financial inflation.
Final Thoughts A key feature of this system is that it doesn't matter if you understand it. You still must gamble, or risk your savings being eaten away by inflation. The gamble by the public as a whole is certain to end in loss, since the elites will always destabilize asset values to the point of collapse. The lose-lose proposition works the same way as literal highway robbery -- you can certainly hold on to your money; you just can't keep your life at the same time. That said, there are times when the elites are likely to be forced to devalue their money, and with it all other conventional assets, against gold, silver and Bitcoin, in order to hold on to power. This makes it statistically profitable to hold non-state-issued assets at those times. (An analogy would be standing at the front of the line to redeem deposits for cash during a bank run, or to redeem pound sterling for gold at the Bank of England just before Britain was forced off the gold standard.) Necessarily, only a minority will profit from this bet, but its existence is a healthy incentive that pushes the elites to minimize financial inflation. This devaluation is conceptually the same as 'banana republics' having to devalue their currency against the dollar because they've printed too much. The typical way to do this is to strongly deny any prospect of devaluation until the very moment, devalue as fast as possible (and devalue enough to keep their system stable for a while,) and deny any further devaluations in future. So, it's perhaps no accident that the price movements of gold, silver and Bitcoin have been long and gradual declines most of the time, punctuated by sharp rises over short periods, and rising overall over the long term. The system is an 'open conspiracy.' Instead of secrecy, it relies on a combination of state power and ignorance by the public. The only sustainable path to achieving a healthy and just system is for the public to wake up. But the devaluation of its issued money against non-state monies shows that, in a subtle but profoundly real sense, the system is a paper tiger. Since the power of the modern imperial system depends necessarily on various alliances of self-interest as well as the perception of its support for classically liberal ideals, if enough people, and people in the right places, refuse to be intimidated, or expose its nature, the system must make concessions, and make the world perhaps a little better. This possibility of piecewise progress exists in all corners of the system, at most times. Here, then, is where our hope must be for the future. It will be a long battle indeed, and we must be prepared for the entire duration.
