Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

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 posts per 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 on YouTube.
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.

Executive summary

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.

Live Demo

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

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.

Scaling

How it works & scales

Architectural Scaling

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.

Economic Scaling

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.

Scaled Deployment

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

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

Getting Started

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...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
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.

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • 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.

Requirements

Scaling

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

Decentralization

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 multi-cloud
  • 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.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. 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).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

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

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

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

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

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.

Dragon Den

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
See above

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.

Other Considerations

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).

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

Open Source

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
  • Preferred license
  • 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.

About ColossusXT (COLX):
ColossusXT is an open-source, community-driven, environmentally conscious cryptocurrency, and an alternative to bitcoin that features better anonymity. It allows people to store and invest their wealth in a non-government-controlled currency and make almost instantaneous and completely anonymous transfers with close to zero fees. Colossuscoin V1 was founded as a long-standing, energy-efficient and environmentally friendly digital cryptocurrency and this concept is being continued.
The question format can be seen below:
-----------------------------------------------------------
Q: What is the Colossus Grid?
-----------------------------------------------------------
A: ColossusXT is an anonymous blockchain through obfuscation, along with the utilization of Armis (I2P). These features will protect end-user privacy as ColossusXT evolves into the Colossus Grid. The Colossus Grid will connect devices in a peer-to-peer network enabling users and applications to rent the cycles and storage of other users’ machines. This marketplace of computing power and storage will exclusively run on COLX currency. These resources will be used to complete tasks requiring any amount of computation time and capacity, or allow end-users to store data anonymously across the COLX decentralized network. Today, such resources are supplied by entities such as centralized cloud providers which are constrained by closed networks, proprietary payment systems, and hard-coded provisioning operations. Any user ranging from a single PC owner to a large data center can share resources through Colossus Grid and get paid in COLX for their contributions. Renters of computing power or storage space, on the other hand, may do so at low prices compared to the usual market prices because they are only using resources that already exist.
-----------------------------------------------------------------------------------------------------------
Q: Why does your blockchain exist and what makes it unique?
-----------------------------------------------------------------------------------------------------------
A: ColossusXT exists to provide an energy-efficient method of supercomputing. ColossusXT is unique in many ways. Some coins have one layer of privacy. ColossusXT and the Colossus Grid will utilize two layers of privacy through obfuscation, and Armis (I2P) these will protect users of the Colossus Grid as they utilize grid resources. There are also Masternodes and Proof of Stake which both can contribute to reducing 51% attacks, along with instant transactions and zero-fee transactions. This protection is paramount as ColossusXT evolves into the Colossus Grid. Grid Computing will have a pivotal role throughout the world, and what this means is that users will begin to experience the Internet as a seamless computational universe. Software applications, databases, sensors, video, and audio streams-all will be reborn as services that live in cyberspace, assembling, and reassembling themselves on the fly to meet the tasks at hand. Once plugged into the grid, a desktop machine will draw computational horsepower from all the other computers on the grid.

How does Bitcoin ATM allow you to purchase Bitcoins?

How does Bitcoin ATM allow you to purchase Bitcoins?
https://preview.redd.it/f2tluqt1cfr51.jpg?width=2400&format=pjpg&auto=webp&s=9c5d4c926fd0ff5af215c26524537c1bf676b77b
Are you planning to invest in Bitcoin, well, there is no better time than today to invest in cryptocurrencies. There are many biotin exchange platforms where you can buy and sell Bitcoin. Amongst the various modes of going ahead with Bitcoin exchange, you can choose Bitcoin ATM for this. It is an easy way to buy and sell Bitcoin using a credit or debit card. When we are talking about bitcoin sale and purchase, we cannot miss speaking about Bitcoin Farming. In simple words, individuals who wish to become a part of the Bitcoin network, then you can do Bitcoin farming, which is nothing but extraction of the value of Bitcoin. Bitcoin farmers or Bitcoin miners solve computation problems, and they get rewarded for the same.
Bitcoin ATM: What should know?
Bitcoin ATM is a simple machine that is used for the sale and purchase of Bitcoin using debit and credit cards. Although Bitcoin has been there in the market for more than a decade now when it comes to Bitcoin ATM, these are a fairly new addition and easy to use and makes it easy for those who wish to exchange Bitcoin do that with ease.
The world got its first Bitcoin ATM in Vancouver, Canada, in 2013. At this ATM, the Bitcoin stalwarts can easily buy Bitcoin using the currency. This ATM is used to convert Bitcoin to Canadian Dollars and vice-versa. After this, Bitcoin ATMs have become very common. As of October 1st, 2020, there were around 10,503 Bitcoin ATMs globally.
Types of Bitcoin ATM:
There are two types of Bitcoin ATM:
· The basic one: These are used only to purchase Bitcoin
· Complex ones- These are used to buy and sell with virtual money. If you plan to use complex ATMs, you need to know that only the members of a particular ATM producer can use the ATM.
Some of the key players that are in the making of complex Bitcoin ATM are General Bytes, Genesis Coin. General Bytes has a market share of 30.3%, and Genesis Coin has a market share of 30.3 %.
The US has the highest number of Bitcoin ATM. Around 83% of the total global ATMs are located in North America.
Bitcoin exchange using General ATM
This is a general process of Bitcoin exchange using Bitcoin ATM, there may be slight variation in this, but the general process remains the same:
  1. The first step is verification (this may vary based on machine
  2. Now, you need to provide a Bitcoin address for deposit at some ATM.
  3. Insert cash into the ATM
  4. Confirm the operation (Bitcoin is sent to your Bitcoin address)
This is the basic step; however, you may find some variation in this based on ATM type. This is the right time to start investing in bitcoin, and with the prevalence of Bitcoin ATM, the task will become simpler.
Concluding thoughts-

Money is a lot more complex than authors realize (40k, Metro, WoW, D&D, IRL)

One of the “easier” ways to create a unique world is to choose a different form of currency. It’s something people notice, since money is ubiquitous. The issue is that money is fairly well developed. It needs to have certain features, or else it flat out doesn’t work.
Examples
In Warhammer 40k, orks use their own teeth as currency. Since every ork has access to teeth, there isn't absolute poverty. Since the teeth decay, hoarding teeth isn't feasible, and it means that orks need to constantly try to expand to get more teeth. Since every ork gives teeth in a tax to their boss, it means that war bands constantly expand and fight, giving the combat happy bastards yet another reason to go to war.
A huge amount of fantasy universes use copper, silver, and gold as currencies.
Metro uses ammo.
In real life, we see many alternative, and ineffective, currencies, ranging from company script, to cryptocurrency, to hyperinflationary national fiat currency, to precious metal based money.
Background
The issue is that all of these are fundamentally flawed in some way as a currency, rendering the economy of that location extremely vulnerable to various shocks that would rightfully upend the entire economy.
A currency fills three major roles 1. A medium of exchange. 2. A store of value. 3. A unit of account.
A medium of exchange means that it is accepted by enough people as having value to be used for trade. Rather than needing to find someone who wants your goods to trade in a chain for something you want (like in every Zelda trading questline), you just give them money and they give you the item. This is why money is more efficient pure barter. It acts to lubricate transactions between peoples.
A store of value means that you won't see all your wealth disappear if you don't spend it now. Which means that you can save up for major purchases, you can make deals that last for years (like mortgages), and people can actually retire on what they’ve earned over the course of their life.
A unit of account means that you know the value of the money and it is standardized. Imagine if the only form of money was in fine art. You could exchange a Van Gogh for a house, and a large spiky suspended ball for a car. Art could fit as a medium of exchange and a store of value, but actually trying to compare artwork to artwork would drive people insane quickly. You'd be in the situation that a dollar isn't worth a dollar, or one Van Gogh isn't worth another Van Gogh. There is no way to convert between lesser and more valuable pieces in a logical manner.
Now, why is that relevant? Because a huge amount of monetary systems in fiction fail these requirements and allow for overt exploitation or unduly hamper the government's ability to respond to threats.
Problems
With regards to the ork teeth, what is functionally happening is constant hyperinflation. Since the teeth decay, there is explicitly no store of value. Which means that the only orks who can afford the best and most fun toys are the warbosses and WAAGH! leaders. There are probably billions of orks who just want to save up for a spaceship or motorcycle or set up a Squig farm of their own, but will never be able to because their money falls apart before their eyes.
Somewhat more seriously, for a race dedicated to war, constantly decaying teeth means that the number of war bands that can attack space based shipping or otherwise need more complex and expensive equipment is limited, reducing the race's overall effectiveness in combat. By attempting to be clever with inflation, by making it so that it couldn't happen, they created the effects of hyperinflation. And, since it is still a money based system, that means that a race designed to go to war can't do it as effectively as they should.
In WoW or D&D or any of a dozen universes where wealth is metal based, using multiple metals as various values of currency would have a similarly debilitating problem. It destroys the unit of account. Basically, the government sets an exchange rate between the chunks of metal, making gold 10x as expensive as silver which is 10x as expensive as copper. But the rarity and expense of gold isn't 100x as much as copper. It is usually much much more. So, it makes counterfeiting extremely attractive, since you can produce 100 small value coins, of the actual metal, and exchange them for a coin of much higher value. Or if it is in the other direction, where you can exchange something where the face value is less than the value of the metal, all the government is doing is funding a small extremely active and profitable metal reclamation industry. This would be an ongoing and unavoidable issue, one that could cripple a government attempting to keep enough money in circulation, or cripple business if the government failed to intervene in an ongoing manner.
Metro has the same issue of lacking a unit of account. The value of a bullet depends on what you're facing and what weapons you have. Even if the nominal value of a .50 cal armor piercing round is high, the number of people who can use it is very low. Consequently, you'll see the value change and possibly invert, as use brings more common rounds out of circulation and makes the more expensive rounds increasingly obviously useless. Without a set value across the board, or something interchangeable and universal, the currency itself will always be in flux, making for a really really shitty form of money.
And a fairly cursory read of human history reveals why being inventive with money is a bad idea.
Company script is money that doesn't function as a medium of exchange. It acts to tie people to a small location and punishes merchants, intentionally gimping economic power of consumers.
Bitcoin, aside from arguably not working as a medium of exchange, fails as a store of value. It is inconsistent and disconnected from reality, making any long term contract in it unfeasible. It has many of the same problems as hyperinflation, except you don't know which direction the value will go.
Less common now, but currencies that are based on the weight of an amount of precious metal suffered from failing as a unit of account. As gold coins were chipped, sweated, plugged, adulterated, or otherwise debased, the value of the coin and the face value became disconnected, and a buyer was dependent on merchants being trustworthy with their scales.
Functionally, money is the way it is because it works fairly well, and the obvious alternatives tend to fail in overt ways. Attempting to be clever with monetary solutions isn't really feasible most of the time.
Solutions
So, are there any currencies that actually make some degree of sense in world, and aren't just "GOLD FOR ALL"?
Surprisingly, yes.
Fallout's bottle caps have surprisingly good arguments around why they are used beyond the water traders of the Hub.
Basically, becoming a medium of exchange is more based on mutual consent than it is on logic.. Shells, pieces of wood, large rocks, feathers, and shiny metals have all been used. Ragnar Benson, of the survivalist fame, claims to have found isolated African tribes that were using Austro-Hungarian bills in the 70s. Unless there's a government that forces something, pretty much anything can and will be used.
By selecting it as a currency, the water traders turned bottle caps into a representative currency, each cap was a certain amount of pure water. They gave it some base level of value that was universally accepted. Outside the Hub, people were willing to trade for them since they had value, prompting other people to accept them on since they could be used in trade, gradually shifting it to something like fiat, abet unbacked by a government. Fallout has a surprising amount of trade across the US, where jet reached the East Coast and the Wasteland Survival Guide reached the West in a couple decades. Over 100 years, it's completely reasonable for bottle caps to become an accepted medium of exchange, valued because people value them.
With regards to unit of account, bottle cap or not is pretty effective. And, since it doesn't have higher denominations, which could introduce the potential for arbitrage, it works. Abet annoying to count out hundreds or thousands of caps of you had to do it manually.
For a store of value, after 100 years as an accepted currency, most large stashes would have been found, and the only input would be through Nuka cola, which is more valuable as soda than caps. And, as described in game, without a press and marking machine, counterfeiting is difficult; labor intensive and involved. There really isn't much way for more caps to come in, which preserves its value. The greatest issue with bottle caps is long term deflation as the population expands, but, while the wasteland continues, population growth will be muted.
Consequently, caps in the Fallout universe ought to provide a stable bedrock for longer term business and functioning governance. Assuming that the world’s inability to actually rebuild despite that being the story for hundreds of years gets resolved.
So what?
So, what makes a good fictional currency? Well, that’s mostly fulfilling the functions of a currency.
  1. Medium of Exchange – that can be nearly anything, as long as it is universally accepted. Attempting to create a new currency for each trader, like some sort of munted script, would be horrible and useless.
  2. Store of Value – The currency should not be easy to counterfeit, which implies 2 things. Either that it is nearly worthless on its’ own (like paper currency) or that the value is derived from a hard to fake commodity, like gold. At the same time, making this needs to be difficult, or else you have the issue of the Elder Scrolls with Transmutation and turning iron into gold, which is also the foundation of their currency. Hyperinflation means broken economies.
  3. Unit of Account – If you’re going to have more than one currency, you need to directly tie them together. More money should be based on the same features as the Store of Value, either just a bigger number on the front, or a larger chunk of hard to adulterate or change money.
And, if you think you’ve solved a major problem, you really really should talk to an economist before designing your world around a special feature.

Can I offload some of the heating load of my electric baseboard heaters on to two old PCs?

Hello I’m in a unique situation. I own my condo, all I have is baseboard electric heating and electricity is cheap at the moment. I also have some leftover gaming machines that are idle (unplugged) and free to use. Instead of heating my home solely with baseboard electric heating I would run the machines and do useful work and get some kind of benefit. Last December I spent over $200 on electricity. I have no plans on using other forms of heating like gas or fireplaces because that would involve renovations. Plus because this wouldn’t cost me anymore than electricity and my time, I’m ok with just having a learning experience/experiment. Small payouts are fine, I have a job.
My questions are which coins could I mine?
Which set up would you suggest?
My first rig is a Q8200 equivalent (actually a Xeon) with 2x PCI-E x16 2.0 slots (I can run two cards in this) with 8gb of RAM and possibly a 750ti and 770.
My second rig is a i7 4770 equivalent (actually a Xeon) with 1x PCI-E x16 2.0 slot ( I can only run 1 card in this) with 16gb of RAM and the 770.
I can run two GPUs in a 2010 era PC or I can run one GPU in a machine with much more RAM and CPU or I can run two separate machines 1 old CPU/GPU, 1 older GPU/CPU. I was thinking I could mine easier coins and convert them to bitcoin instead of trying for bitcoin directly.
Electricity is $0.12 CAD/$0.09 USD per kWh.
Hopefully I’m in the right subreddit, please let me know if there’s a better spot to post this.
TL;DR Can I offload some of the heating load of my electric baseboard heaters on to two old PCs?

Filecoin | Development Status and Mining Progress

Author: Gamals Ahmed, CoinEx Business Ambassador
https://preview.redd.it/5bqakdqgl3g51.jpg?width=865&format=pjpg&auto=webp&s=b709794863977eb6554e3919b9e00ca750e3e704
A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

Dash Core Group - Desperately Seeking Bankers

Introduction
This story starts with DCG and it’s relationship with Dr. Darren Tapp of ASU (Arizona State University). But Dr. Tapp does not stand alone, for there is a loose network of friends with a shared agenda, not only to make dash a regulator-friendly project but to wilfully weaken end-user privacy by upholding a principle of transparency-first.
More than ever, society is engaged in a war on privacy. And when it comes to financial transactions, DCG has taken the position of transparency-first. In sharp contrast, many other projects in this industry are either improving end-user privacy (decred, tezos etc), or actively pursuing privacy first (monero, beam etc).
As you may know, the scaling wars of the past revolved around block size, eventually giving way to “big blocker” projects like bitcoin cash and dash. By enforcing small blocks, Blockstream successfully syphoned off miner fees to the Lightning Network and it’s own Liquid Network. I believe we may be witnessing a similar event with dash. This time it’s not a scaling issue, it’s a privacy issue; transparency-first vs privacy-first.
The Power of Inaction
As many of you know, Dr. Darren Tapp is a research professor at ASU. And you may also be aware, in July 2019, the dash treasury paid ASU 345 dash for research into zero-knowledge proofs. Here’s an excerpt from the proposal along with the relevant link:

“This proposal seeks funding to renew our annual funding commitment to ASU’s Blockchain Research Lab and specifically to fund a research project which would investigate methods to apply zero-knowledge proofs to blockchain identities. It is possible Dash could leverage this research to apply zero-knowledge proofs to identity functions within the Dash network.”
https://www.dashcentral.org/p/dash-core-group-research

To date, there has been zero feedback from this project and, so far, all requests for an update have resulted in silence, including it’s omission from the DCG quarterly call.
I am particularly concerned by a seemingly gross contradiction. The result of this research into zero-knowledge proofs was to apply to blockchain identities but not to actual payments when they hit the dash blockchain. DCG and it’s proponents argue that privacy-first negates the ability to audit the chain for inflation. But if this was true, how can anyone argue with confidence that zero-knowledge proofs would only work with blockchain identities? It is, I say, a bit disingenuous to suggest it can work one way but not the other.
A Tapp Perspective
I now want to draw your attention to a recent interview between Joel Valenzuela and Dr. Darren Tapp on 8 May 2020:
https://www.youtube.com/watch?v=Tikj0O0xphE

Here is a particularly pertinent quote from Dr. Tapp:

@ 1:06:13 DT: “Well, I’ll just tell you my use case for dash, right. You’re talking about your use case. My use case for dash is, well, I’m not going to worry about the coffee guy thinking I have a whole bunch of money because I’m going to pay with my phone and I’m only going to keep a small amount on my phone, right? So that right there, they would have trouble you know, they have to go a few steps back and then they’re not even sure if it’s mine if there’s no Private Send. Um, if I don’t use Private Send. And if, let’s say, if I did want to take some money and put it into Coinbase. Well, if I don’t use Private Send and they’re asking “where’s the money came from?” - and that’s what they’re going to do - it’s going to be a little bit easier to say, “this is where it came from”, right?. I mean, I wouldn’t lie to them, I’d tell them the same thing no matter if I used Private Send or not, but I just think I’m going to have less problems with the bank and stuff if it wasn’t so obfuscated. So yeah, I think there’s a kind of, I think there needs to be room for both on chain. There needs to be.. I mean, I’m glad you’re enjoying Private Send. I think there are some improvements that can be made to Private Send. Umm, but I mean, there were some discussion of MimbleWimble and there is, no, we do not do that. No no no. But like, I mean, if you want to bring over some improvements, maybe start reading about the Cash Fusion that’s on the Bitcoin Cash. Umm, so err and like, I believe if you read Cash Fusion, their paper, I believe we can do Private Send in a way where the masternodes doesn’t know which output corresponds to which input. So, right now we trust that the masternodes aren’t paying attention, aren’t going to, you know… they’re... yeah I mean, and they have the word trust in it, they have a vested interest in the network working so that Private Send works the way it’s supposed to work. But, you know, at the same time, if you can do some small little cryptographic thing for no real cost on your processors and stuff like that, umm, why wouldn’t you? So that’s one thing I think that can be brought in. I think Cash Fusion also might do a better job of keeping the balance separate or something like that, but err., I would definitely be in favor of improving Private Send. Umm, but also at the same time, I’m glad that I’m given a choice if I want to use it or not. And pretty much anything when I’m interacting with the banking system, which I know you’re doing a fiat-free, so you don’t need to worry about that Joel.. but when you’re interacting with the banking system, the easier it is to explain to them, the better off, the easier time they’ll give you. That’s the way it is.”

In other words, Dr. Tapp’s priority is transparency-first for the benefit of the banking system.
What I found particularly interesting was Dr. Tapp’s body language. While he was making the above statement, at 1:07:04 he says, “I wouldn’t lie to them [the bank]” and at this exact same moment he goes to touch his face and pulls back. This is a body language clue that he’s lying or somewhat anxious about saying this. This doesn’t mean he is actually lying because with body language you normally need multiple clues to be sure, but having watched it multiple times, I am personally more convinced than not that he was in fact lying or anxious.
Dr. Tapp has outright rejected MimbleWimble, which is fine because MW is just one of several privacy enhancing technologies. But given the complete lack of feedback regarding zero-knowledge proofs from ASU. And given Dr. Tapp’s stance on transparency-first for the benefit of the banking system, I am wondering if there’s more to this than just one person’s opinion on the matter.
The Yes Chain
DCG asserts that dash has fewer privacy features than bitcoin. To make this case, considerable effort has been made to educate exchanges and regulators:
https://blog.dash.org/dash-complies-with-the-financial-action-task-force-fatf-guidelines-including-the-travel-rule-a4c658efc89d

According to DCG, the benefits of a transparency-first approach are:
a) Transaction monitoring
b) Identifying and blocking transactions that utilized mixing, or are in close proximity of known bad actors or sanctioned wallet addresses.
c) Track anonymity enhanced convertible virtual currencies and wallet addresses sending more private transactions.
d) This means that the VASP can choose to identify, block, and report on all transactions sent with Dash PrivateSend and can track and report on all the components of a mixed transaction.
e) Reporting on your users’ blockchain transactions
f) Establish an automated record keeping system for suspicious activity
g) Activity reporting, customer due diligence, and currency transaction reporting.
h) Track anonymity enhanced convertible virtual currencies and wallet addresses sending more private transactions.
i) Customizable risk scoring

Clearly, the scoring / ranking of coin histories (“risk assessment”) is producing a situation where some coins are more worthy than others.
Let us also consider the recent initiative to get dash re-listed on Japanese exchanges at a cost of 428 dash: https://app.dashnexus.org/proposals/listing-dash-in-japan/overview
Coinfirm-ation
For a number of years, in pursuit of regulatory approval, DCG has been courting chain analysis companies. This started in August 2016 when Robert Wiecko (Dash COO) was invited to attend a bitcoin meetup in Warsaw where he met Pawel Kuskowski (CEO and co-founder of Coinfirm) . Here is the original proposal along with the subsequent Coinfirm interview with Amanda B Johnson:
https://www.dash.org/forum/threads/dash-on-warsaw-block-on-25-08-2016.10211/
https://www.youtube.com/watch?v=KJOhIkeK3Ho

Mr Wiecko’s original proposal failed to mention any relationship or intention to engage with chain analysis companies. Nor was it mentioned that this meetup itself was sponsored by Coinfirm. It comes with little surprise that Robert Wiecko does, in fact, have some experience working with compliance (see @ 27:05 of Amanda’s video).

“Btw, we have, both of us have a compliance background. My last job was with [inaudible] bank, before that within a banking compliance department”

Block the Blockchain
Karen Hsu has a long history with dash. Formally from BlockCypher, she helped dash with various integrations, including Payza. She is now CEO of BlockchainIntel and in April 2020, she helped to facilitate an integration with Reciprocity Trading.
https://blog.dash.org/dash-core-group-reciprocity-trading-and-blockchainintel-focus-on-transparency-in-digital-currency-7a71c8ff84ec

“As more people will be interacting online now and potentially in the future, it will be increasingly important to provide transparency so people can trust those they cannot see,”

Karen is interested in blockchain, machine learning and analytics. And in 2018 she worked with various law enforcement agencies to help track and trace five million dollars worth of dash, allegedly stolen from a retired couple:
https://medium.com/@karenhsumaif-you-have-digital-evidence-for-a-theft-whats-holding-up-justice-e7ebf99eddf0

“The thieves didn’t move the funds right away. A couple months after the initial theft, they started to move the funds to multiple wallet addresses across the world. During their hundreds of transfers, the thieves converted the Dash into other cryptocurrencies. We were able to track their every transfer, whether it was from one Dash address to another, or from a Dash address into another cryptocurrency. In the end, the thieves had transferred the stolen Dash into hundreds of different wallet addresses and exchanged the Dash for Bitcoin, Ether and Bitcoin Cash.
We collaborated with the FBI and traced the funds to an exchange in Asia. Through our connections with that exchange, law enforcement was able to obtain details of the account owner, which led to a bank account. By September 2018, three months after the theft, our tools and collaboration with law enforcement had identified a person involved in this theft. At that point, the victims, law enforcement and us at BlockchainIntel were hopeful there would be some recovery of stolen funds. But that’s when things slowed down. A lot.”

The narrative is clear; an innocent couple were victims of financial crime. Did the thief use Private Send? Was the thief dumb enough not to use Private Send? Is this the type of scenario that Dr. Tapp endorses for transparency-first when dealing with a financial institution?
In contrast, let us take a look at a story from January 2017 by NIAC (National Iranian American Council):
https://www.niacouncil.org/press_room/niac-concerned-u-s-banks-denying-financial-services-iranians-u-s/

“Over the past few years, Iranian visa-holders resident in the United States have seen their bank accounts at U.S. financial institutions shuttered as a result of U.S. sanctions. The most recent case is that of Chase Bank, where NIAC has learned that Chase is closing the bank accounts of Iranian visa-holders. NIAC is deeply concerned that U.S. banks are denying financial services to Iranians in the United States on the basis of their national origin and calls on Chase Bank and other U.S. financial institutions to cease and desist from such discriminatory policies. At the same time, NIAC believes that the repeated nature of these account closures makes it incumbent on the U.S. administration to take immediate steps to provide clarity as to the scope of existing U.S. sanctions laws — none of which bar U.S. banks from opening and maintaining accounts for Iranian visa-holders resident in the United States.”

Great! Who needs banks when Iranians can use dash! But then again, what if the recent history of your dash coins was linked to an innocent Iranian, disqualified and excluded by sanctions?
Closing
A global peer-to-peer electronic cash system needs to be cheap, fast and very easy to use. Dash’s technical ability to meet demand is very much in sight and the Velocity protocol certainly seems promising. But digital cash also requires a high degree of fungibility. The less fungibility there is, the more discretion and division it sows. The path of a coin should not unduly taint a person’s reputation.
Incremental improvements have been made to Private Send but it is today, fundamentally, the same as it was six years ago. Mixing takes a long time and the user requires knowledge to use it in a safe manner. For example, external actors proactively breaking VPN connections to reveal the underlying IP address during mixing.
A poor user experience is probably why Private Send isn’t used very much and that seems like a very convenient situation for those people actively pursuing regulatory approval. I have to wonder, has the internal workings of DCG been compromised by state level actors? Is this why key members of DCG have refused to undergo a polygraph test?
