Can I prove my BitCoin balance to a complete stranger, safely, over the Internet?

I'd like to prove, verifiably, to some contestants in a contest I'm setting up; that I'm on the level and I do indeed have a prize ready to give to the winner.
I'm not talking escrow, I don't know who specifically is taking the money yet, they haven't contested yet and it doesn't start for another 9 weeks.
So, I'm trying to offer a cash prize, and to show off the bling on flyers and stuff.
I can't write "Grand Prize 0.0005 BTC" because that looks fucking lame, right?
What can be put on the poster to really get people's juices flowing?

Ledger Isolation vulnerability is much more dangerous than people might think

The recently revealed vulnerability in Ledger is much worse than people might think.
At least I could see on Ledger and Bitcoin subs, that people think, they are safe if they do not download some malware on their pc/laptop.
But this is wrong.
The issue can be exploited also when you use only standard applications on your Ledger which are affected (BTC and its derivates)
The attack vector here is, if some tricks you to interface with the malicious web wallet with your Ledger. (so no you do not need to install anything to lose your coins)
As an example:
  1. the attacker sends you a link for LTC web wallet (he says it is a new really great wallet and want you to try or whatever other reason)
  2. you think you are safe, after all, Ledger protects your private keys and everything has to be confirmed. So you connect and will try to send out some LTC to the attacker just as a donation or anything else.
  3. The web wallet sends spoofed transaction to your Ledger, so you think you are confirming LTC transfer, instead your BTC is sent out
There are many scenarios like this. You are affected anytime you interact with your Ledger and any web service. (not only if you use fake sw wallets)
I explicitly asked about it and this attack vector was confirmed by Ledger.
Stay safe.

Why can't I sign and then broadcast my transaction??

Can someone please help me broadcast a transaction? I have the full redeem code, and my original Wallet address, it keeps saying "mandatory-script-verify-flag-failed (Operation not valid with the current stack size) after broadcast transaction". I have to sign it to receive the money to my address...? Why wont it work?!

A word of caution about exchanges, privacy and your permanent history on the blockchain

I had an account restricted on a major exchange this year and it's not a pleasant experience. Just wanted to share my experience, since I see so many have been through something similar in several exchange-related subreddits. My case happened at Bittrex but I think it's important to note that this may happen on any exchange, not just Bittrex. People are depositing way too much trust in these exchanges and it may come back to bite them. Here's my experience as honestly as I'm able to put it. Bittrex is technically great, contrary to what many say the system just works. Works great in fact, fast and very few glitches in many many years. I think I must've been a very early customer back when things were very informal and until 2020 I had absolutely zero problems with Bittrex. I always thought they were above the pack when it came to system security design and reliability. Despite joining when it was very early, I did full KYC and had the top tier withdrawal limit even though KYC wasn't obligatory back when I joined. I did it all formally because I wanted to have a sort of bank account I could trust, I didn't want to be jumping from exchange to exchange like some crypto traders did. I never used as much as 0.01% of this withdrawal limit, I'm small fish but it was nice to know I could move tons of BTC like the whales if I ever needed to. So I sent them all my real data, work address and so forth. Then Bittrex got moved out of USA and into some country, don't know where. Which was fine by me, I thought it was the same people behind it, doing some formality. Then one day a person with a drawing for a profile pic and some strange username decides to contact me out of nowhere using the Bittrex tech support interface. They know everything about me, but I don't know anything about them. No contact info visible, nothing. This support person sends you a statement you must sign and then based on that they begin to ask for specific documents. I wanted to keep my relationship with Bittrex, so I filled signed and returned it. Then they dived into each item in the thing requesting more documents based on each. So if you said you previously worked for ACME, they'll ask to see ACME related stuff. I said I bought Bitcoin using Bank X, so they wanted to see Bank X statements. And so on. They begin to dig into each specific item you inform. Then it downed on me that maybe I was under some formal audit, in which case I'd have the right to know so I could hire an accountant or lawyer. So I politely asked. They don't tell you anything. You don't even know who the person is on the other side, there is no identification at all of who's contacting you. You're sending all your personal informations to someone who, as far as you know, could be a cat or a dog typing on a random keyboard. So I then asked them why so much detail was needed, since I'd provided lots already. They ignore and just say thank you for your cooperation and proceded to ask for more stuff. I said fine let's do this and went along. Then they asked for specific crypto addresses for the tokens I'd used in the past. Like the address of whoever sent me some XXXX token years ago. I then thought hey man this is too much, do you need me to fax or mail you my ID or something, I'd do it but whatever I enter in there could spell trouble for me. For example, if some guy whose ETH address did something nasty, but coincidentally paid me years ago using that same address, if I gave them my address from the past, in those several years it could mean this person is now a wanted criminal and it'd spell trouble for me, who knows what the person did afterwards, then my account would be forever linked to that rogue address. I began to reflect on this and thought wait, this is not good, I could put myself into a 'bad address' database for no reason. Then I told them I would not send the crypto addresses. They said thanks let's continue the process. It felt weird overall, it just keeps going and demanding more information. I then asked for someone to speak to or somewhere physical I could go to, to talk and show that I'm a real person, they never reply anything, they just ask for more. So I finally gave up and stopped replying and they apparently restricted my account or something. I'll have to go back and reopen the ticket and request account reactivation but then they'll probably restart the same process again. I'm not really that much of a fan of crypto these days, so I'm thinking maybe it's time to call it quits. The reason I'm writing this is to let everyone know that whatever you do in crypto gets forever linked to you. You begin thinking it's some informal thing and that there's some freedom but there really isn't. You may fool around with crypto but then someone is recording everything and will demand you make everything formal in the future. When I joined Bittrex everything was more informal in crypto, even shapeshift and others allowed you to trade crypto with no ID at all, 100% anonymous. Heck even faucets gave out free Bitcoin back in the day. Then all of a sudden everything you do in these exchanges will be audited and you'll need to provide formal documents for everything you did in the past 10 years. Some anonymous operator (this isn't specific to Bittrex, all of them do it that way) with no office has all your info but you know nothing about them in return. You don't even know where these exchanges are located at all. I saw a Facebook post about Binance not even having a formal country, they're "all over t he place". Sure that sounds cool but...who do you turn to when they demand legal stuff from you? Someone out there has all your financial information but you have nothing, you have no security, no legal protection, nothing and they have everything. So, be careful. This isn't all specific to Bittrex, any exchange can and probably will do the same. Point is crypto is a formal thing and will spell trouble for you in the future. Especially since blockchain analysis is way too primitive still, your addresses could somehow end up in a bad neightborhood. The pandemic kinda reminded me of blockchain transactions, you may end up infected because you have no way to know what others have been doing while you were doing everything right.

The loss of bitcoin

Hello. I use the Wasabi app with the Coldcard MK3 cold wallet connection. Left Bitcoin for storage in the wallet. Recently I wanted to make a Deposit to my wallet, but I discovered that there is a missing amount of Bitcoin on my balance. There is also a transfer to an address unknown to me. I did not make this transfer and did not confirm it. I want to find out how I lost my Bitcoin Or what vulnerability I have. When creating a wallet and installing the app, I followed all the security instructions, as well as used virus protection tools on my computer and used genuine original software.

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.

He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.

Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:
Long red or green candles. This is a crypto signal that tells you that it is not favorable to trade at the moment. Found on candlestick charts.
Digital Signature:
An encrypted digital code attached to an electronic document to prove that the sender is who they say they are and confirm that a transaction is valid and should be accepted by the network.

Frictionless:
A system is frictionless when there are zero transaction costs or trading retraints.
FUD:
Fear, Uncertainty and Doubt regarding the crypto market.
Gas:

More fun with OP_HODL (CheckLockTimeVerify)

Last week I wrote a post with a script to create a HODL address. A HODL address is a UTXO that cannot be spent until a certain epoch time or blocktime. It can be used to secure funds in a will or trust that has a designated maturity date. Or you may have some other reason to lock the funds, the point is that the UTXO can be physically verified to be funded, and under an unbreakable timelock.
I've liked the feature but have been frustrated that there is limited HW and SW wallet support for it presently. My previous post walked through how to make a segwit HODL UTXO, this post will detail how to make a BIP16 legacy P2SH HODL UTXO.
Similar to last week, I wrote a bitcoinlib script to do it, but this week I also went through the steps to do it on the CoinBin wallet. CoinBin is a JavaScript wallet that can (and should) be run locally. CoinBin, or raw python (bitcoinlib) are the only ways I currently know of to spend a HODL address.
Here's the basic rundown to create and fund your UTXO with CoinBin
  1. Use either Electrum or Bitcoin Core to collect a Bitcoin public and private key.
  2. Run the CoinBin app either locally (best option) or through the live site
  3. Choose New -> Time Locked Address
  4. Enter the public key (from #1) and either a block height or timestamp for your lock
  5. Hit Submit and record the address and redeem script
  6. Ensure you have accurately recorded everything in step #1 and step #5
  7. Send funds to the address recorded in step 5 as you normally would.
Here's the basic rundown on how to spend your UTXO with CoinBin
  1. Use either Electrum or Bitcoin Core to collect an address to spend your UTXO to
  2. Run the CoinBin app either locally (best option) or through the live site
  3. Choose New -> Transaction
  4. Enter the Redeem Script you copied in the creation process (step #5), then Load
  5. After a few minutes it should automatically load your UTXO into the form
  6. Enter the address you want to spend your UTXO to and adjust the output amount for fees
  7. Hit the question mark next to Transaction Fee for the calculator
  8. Hit Submit when satisfied and record the unsigned transaction data
  9. Select Sign on the top nav bar to begin the signing operation
  10. Enter your private key from the creation process (step #1) and the unsigned TXN
  11. Select Submit to produce the signed TXN
  12. Broadcast the signed TXN with either Electrum or Bitcoin Core
Note, if you try to broadcast before the UTXO's timelock expires, you will get a terse not final error in either Electrum or Core.
For Extra Credit, CoinBin can also be run against Testnet, but to do so you have to unhide the settings element, manually code the TXN input script and manually code the TXN nLockTime to sync with your HODL address.
Here are a Testnet and Mainnet HODL spend TXN I created in CoinBin * Mainnet: txid ea6a1...79d53 * Testnet: txid a8110...adc93

What is the path of least resistance to create a small store that accepts crypto? (BTCPayServer woes)

I tried to set up a store for stickers and stuff like that over the weekend, that could accept Bitcoin. I thought BTCPay Server would be easy, but this was my experience:
1) I've heard BTCPay Jungle is easy and good, I go to their website and it is only configured for the site owner and no obvious way to create an account, I guess it shut down?
2) I head to the BTCPayServer docs to find other third party hosts and find this list. I try about five most have the same problem as #1. One does allow me to sign up but won't let me continue without verifying my email. Unfortunately they never send the email to confirm.
3) I try to set something up in Google Cloud with the docs which links to this Github README which has a broken link to a YouTube video. Also the instructions do not work after trying them as is.
Isn't this the project sponsored by Square? Am I an idiot that I can't get this to work or is it just broken? I'm willing to try again and even go so far as to set it up on my own Raspberry Pi but given the investment of money and time and my experience so far I don't want to do that only to find out it does not work.
TLDR: do you know how anyone has set up a store that accepts crypto and how did they do it? (I prefer to accept Bitcoin)
Thank you community for your memes and help. HODL and all that stuff.

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:

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.

API Documentation

APIs (on chain & off)

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.

Monthly Update: Parachute Social Liquidity Pools, Ivan(OnTech) Joins as Advisor, Townhall, Trending on CoinGecko, Covered by EllioTrades Crypto + Altcoin Buzz, …– 31 Jul – 3 Sept'20
Hola folks! Yesterday we got caught up with everything that happened in July 2020 at Parachute and ParJar. Today, I will be sharing news from August. Looking back at those five weeks, they were easily one of the most action-packed ones in the Parachuteverse ever. If you missed my note about the new format from yesterday: “…I thought it would be best to club all the Parachute news into monthly reports and publish them back-to-back over the next few days to catch up with the latest…For a change, we will be focusing on Parachute + ParJar news alone in these monthly reports. Because if we include news from our partner project in these, we might as well publish the Encyclopaedia Britannica”. In case you thought yesterday’s was a long read, boy are you in for a shock today. Make sure to get yourself a beverage and set aside an hour to go through all that will follow. So here’s goes the Parachute scrolls dating 31-Jul-20 to 3-Sept-20 –
31 Jul – 6 Aug'20:
$PAR became one of the top trending coins on CoinGecko this week. The token also received a perfect score on DEXTools. Pretty sweet! We crossed 2500 members in the Parachute channel after quite a while. But no sign of Ron yet. Haha. BrainiacChess Network ($CHESS) was added to ParJar. We got a surprise listing on Hotbit ourselves with an ETH and BTC pairing. $PAR was listed on CoinW exchange this week too. More details here. Looks like wrapping up a day at Parachute usually ends with steaks. If you ever thought otherwise, a look at the $PAR contract should dispel that doubt. A community vote was opened up to list the next token on ParJar. Congratulations to Chirag for winning this week’s Parena and taking home 6k+ $PAR. Neat! Everybody knows about the bitcoin pizza.

Pic of Gian with Diamond Dallas Page taken from his epic WCW Thunder story (https://t.me/parachutetokengroup/395125). Spooky sent us!
Gian announced a temporary stoppage of Two-for-Tuesday to make way for the second annual Big Brother contest. Soon after, he opened up entries for the contest. Woot! Fans can also get updates and spoilers from the GC’s BB group. Gamer Boy hosted a “Random Gk” trivia in TTR this week. Naj hosted a Sunday “Mega Trivia”. Afful held a “General knowledge” trivia as well. Sebastian shared the new ParJar Gaming schedule for August. Yes, you read that right. 75k $PAR in the monthly prize pool. Woot! For this week's Friday creative prompt (#nottodaycovid) by Jason, Parachuters talked "about what you are doing to keep yourself sane during the pandemic" for some cool $PAR.
Alejandro’s betta fish collection is a sight for sore eyes
Elmar, these are all amazing!
Model ships made by Bada during the lockdown. Awesome!
Ivan (from Ivan on Tech) joined the Parachute channel this week. Looks like next few weeks are going to be super exciting! Doc Vic hosted a flash game in the Parachute War Zone for some cool $PAR prizes. Mario had an interesting idea. Change the ParJar display name to “ParJar Wallet” to actually reflect the true nature of ParJar. And voila! “ParJar” is now “ParJar Wallet”. Instant feedback implementation! We also finally got an unofficial price chatter group running. As we mentioned in the last update, Clinton released a limited edition shirt in the Parachute Store this week to commemorate the Liquidity Program on Uniswap. Some of the Parena merch had to be sunsetted from the store though. So if you grabbed some before that, you are now the proud owner of rare Parena merchandise. James from the Parachute Athletics and Running Club announced a Secret Challenge for 400 $PAR. Cap shared a sneak peek into what’s brewing behind the scenes. He also posted some experimental visuals for the website and for ParJar:
Cap’s creative spurts are super trippy! Pt. I
Trippy creatives from Cap Pt. II
7 Aug – 13 Aug'20:
ParJar did some heavy lifting on behalf of Uniswap this week when Uniswap got clogged but ParJar swaps were running smoothly. If you haven’t seen how swaps work yet, CF made another cool video tutorial. Following last week’s community vote, Enjin ($ENJ) won a spot to become the next swappable token on ParJar. DMM DAO’s $DMG token was listed on ParJar as well. Inputs from the community were taken for listing the next DeFi token on ParJar. A new tier was added for the Parachute Uniswap Liquidity Rewards Program this week. Last week’s incredible Parachute run on CoinGecko was noticed by many including DAO Maker and Blockfyre. We got word that Parachute was featured in Ivan’s (Ivan on Tech) private report meant for his closed group of subscribers. Word on the street is that Parachute was reviewed in detail in the Hidden Gems section of the report and received the highest score among all the projects covered there. Super cool! He also talked about Parachute in his latest video. Watch out for timestamps 42:23 and 47:48. And followed it up with another mention in next day’s video as well. Pretty cool! $PAR also saw some crazy movements and activity. And all this started while Cap was chilling on an Amtrack on his way to Vermont. Haha.
Cap shared this amazing view from Vermont
Check out the Sentivate gear in the Parachute shop. For this week's creative prompt (#donkeyart), Jason had Parachuters "find an image of a piece of art that particularly moved" them and explain how and why. Darren’s Mega Friday Trivia in Tiproom had a sweet 6300 $PAR prize pot. Peace Love (Yanni) hosted another quiz in TTR with some more cool $PAR prizes. Clinton’s charity For Living Independence (FLI) became Lumenthropy’s spotlight charity this week which means they will be matching all $XLM donations to FLI. Lumenthropy is Stellar’s charitable arm. The entries to Gian's Big Brother Contest closed this week with Gian starting to share updates on episodes and $PAR rewards to weekly winners. If you want to catch all the action, head over to the BB Group set up by GC. And the most amazing thing happened this week – As new folks were joining into the Parachute group, someone named Ender Wiggin chimed into the chatter and as we talked we figured that he was not only Cap's neighbour in NYC but was also my school senior. Parachute truly brings the world together! PARs & Recreation wants to create a Parachute foodies group. And if his posts are anything to go by (figs, blueberries, Ikura), it’s going to be a hunger-inducing channel. Doc Vic (from Cuba) announced the start of a team Deathmatch tournament in the Parachute War Zone.
Congratulations, Clinton!
Looks like an epic ParJar video is underway. Parachute was also covered extensively by EllioTrades Crypto this week. YouTuber CM TopDog too made an awesome video on Parachute where he talked at length about the project, the roadmap, the token and more. Saweet! After seeing Albundy185 struggle with pooling on Uniswap, Cap and Ice had a light bulb moment for an entirely new feature on ParJar that would make pooling social and fun. More details to be released over the next few weeks.
Jose’s epic new gif puts Cap’s lightbulb moment about social pools into perspective :D
Looks like Alexis’ neighbour is into Uniswap pools as well. Get it, get it? Haha
Congratulations on the new store, Hang! Folks who don't know, Hang is building a hempire. World domination next
14 Aug – 20 Aug'20:
As mentioned last week, Cap and crew had something cool brewing for folks who pool assets on Uniswap. Presenting Social Liquidity Pools (SLP) by Parachute. No more pooling/staking alone in silos. Get together with others doing what you love most – pool assets on Uniswap (either directly or through ParJar - upcoming), then stake the received liquidity tokens into SLPs on ParJar to get additional rewards and social bonuses like entry into VIP or premium token curated groups. Making Uniswap social! Click here to read about what’s next for ParJar and Parachute. The first Uniswap $PAR Liquidity Pool Rewards Program came to a close. All qualified poolers will receive their rewards in 2 months. DeFi superstar yearn.finance ($YFI) was added to ParJar this week for both sends/tips and swaps. Woohoo! Waifu in the house. After last week’s community inputs regarding the next new token on ParJar, a public vote was started. Uptrennd founder Jeff Kirdeikis’ latest project, TrustSwap ($SWAP), got listed on ParJar after winning that vote which got a shoutout from Ivan as well. So now we have a tongue twister on our hands. Haha. Cap also shared the first hints about $PAR governance. More details to be posted next week. Plus, Cap announced that he will be hosting a townhall next week. Stay tuned! Get your questionnaire ready. Like last week, Parachute chatter popped up in Ivan’s latest video this week as well.
Dang! What an amazing place, Victor
For all the mobile gamers out there, Tony set up a Parachute Corporation for the EVE Echoes game. Hit him up if you want to join. Naj hosted a Sunday TTR trivia with a 6300 $PAR prize pot. Gamer Boy held one as well. Darren’s Mega Trivia in Tiproom was super fun as always. Jason did an impromptu token giveaway so that fellow collectors could complete their ParJar collection followed by a mini contest to "guess the closest to the number of miles I am about to run" for some cool $PAR. Chris hosted this week’s creative Friday prompt (#adminfunday): “Using the profile image of any Parachute admin as inspiration, draw what you think that admin would like to do on the weekend”. And what an amazing video Hans (Pad of DeFi Chad). Haha! Super hilarious and fun.
Some of the radest #adminfunday entries. Clockwise from top left: Skittish, TyReal, Staph It!!, Yosma, Ik Now, Jeff, Chica Cuba, Jhang, Kuuraku
21 Aug – 27 Aug'20:
Ivan (from Ivan On Tech) joined Parachute as an advisor. Woot! Welcome to the Parachute fam. Here’s a sneak peek into what the first day discussions with Ivan as an advisor revolved around. The project got featured in France’s largest crypto news platform, Journal du Coin. Noice! Click here for the English translated version. As mentioned earlier, Cap hosted a townhall this week. If you missed it, you can catch up here. He also shared a rough draft snapshot of “how the governance and fee distribution contracts could look for ParJar Wallet”. Plus, some updates from this week and a big picture view at what staking liquidity through ParJar could look like. Parachute also got mentioned in another of Ivan’s videos this week.
Snapshot from the Parachute Townhall
In partnership with Sentivate, ParJar distributed $SNTVT tokens this week to 1500 people of whom 800 were new users. Sentivate hosted this drop for members of a specific group as a token of appreciation for their support. Reminiscent of the AMGO drop, this was a precursor of “how PAR drops + other token drops could work for our Social Liquidity pooling”. The $PAR Governance whitepaper was released and initial brainstorming started in the tokenomics group. Cap was also interviewed by YouTuber Money Party (@Edward_F) this week to talk at length about where we are at and where we are heading. We also received a super duper shoutout from CryptoTube in his latest video where he did a deep dive into ParJar and Parachute. Thanks a ton! Cryptovator did a cool feature on the project as well.
Cap added more changes to the site to show: \"ParJar wallet in action along with…the integrations\" + Big Picture
In this week's creative contest, Jason put up a #writingprompt: "...imagine you are a brand new intern at my new mega corporation...Today is your first day and you are told you need to present something about crypto to upper management...all you know is Bitcoin is a thing and some vague information about it. Pick a coin or general crypto subject and write a short story...None of the facts or material can be correct in your presentation...". Haha! After helping fellow Parachuters with their ParJar collection last week, Jason set up a collector’s group this week. If you have more than 30 of the coins/tokens listed on ParJar in your @parjar_bot collection already, send Jason a PM and he will get you in. Victor hosted a “Big Trivia” in TTR this week for 6300 $PAR in prizes. Afful held a quiz in Tiproom on “General Knowledge” as well. Check out these wicked new shorts in the Parachute Store based on Jose’s gif.
Epic stuff, Jose! Haha
Nice haul from the Parachute Beer Exchange, CF! Markus did you a solid
Boldman Stachs pointed out that $PAR had the highest Galaxy Score on social media analytics platform LunarCRUSH this week. Pretty neat! CF took note. And like Cap mentioned, it has mostly been thanks to him. Haha. And big up to Jesús (@JALBARRAN02) for making a ParJar guide video for our Spanish crew. You rock! Interesting results from the DeFi survey: majority of crypto folks are still DeFi-curious. A new community vote was thrown open for listing the next DeFi token on ParJar. Anyone who's been around a bit already knows that Clinton does some amazing work at his charity, For Living Independence, which creates assistive technology for disabled individuals. This week he shared some snaps of a build which now enables a lady in a wheelchair get upstairs in her home.
This is so wholesome, Clinton! Thank you for doing what you do.
28 Aug – 3 Sep'20:
ParJar was featured in Altcoin Buzz’s latest video. Noice! Click here and here to read some recent updates from Cap. After winning last week’s vote, Akropolis ($AKRO) became the latest token to be listed on ParJar. Woot! bZx crew gave some serious competition too. So we had to get them on ParJar as well. $BZRX was listed this week right after $AKRO. $PAR now has 7k on-chain HODLers. Saweet! Sentivate will be our first partner project to have a Social Liquidity Pool on ParJar. This is amazing! Time for another community vote to get a new project listed on ParJar – this time it is DeFi Pie v/s Ren v/s Proxi DeFi v/s Others. If you’ve missed all the latest Parachute-related videos, we have your back. Check this tweet thread to catch up. Naj hosted a Saturday Tiproom Trivia for 6300 $PAR in prizes. Congratulations to Maria for winning the latest Parena. 8k $PAR in the bag. Woohoo! And congo rats to Yanni as well for winning a special edition shirt from the Parachute store. Gamer Boy’s Big Trivia in TTR saw a ton of participation as always. The Parachute Fantasy Football contest is back! Chris set up the entry rules this week.
CF has done wonders for Parachute’s social metrics: “..+500% in our fi(r)st marketing month..”
Whew, what a month! And with that we close for August 2020 @ Parachute/ParJar. See you again with one more epic monthly update tomorrow. Cheerio!

Free £10 from Luno (almost instantly!) for buying £100 worth of bitcoin

Luno is a platform that's been around since 2013, allowing you to buy and sell bitcoin. They're offering £10 in Bitcoin when you purchase £100 worth of BTC (for the EU the offer is €15 for a €250 purchase).
Steps:
  1. Sign up with my referral link and verify your identity (non-ref, no bonus).
  2. Enter code WK7D5T in the "Rewards" page of the Luno webpage or app. If it says something like "this promotion can only be used once," it means the referral code has already been applied during sign-up, so you can move on to the next step.
  3. Buy £100 in Bitcoin (EU users - €250). You can deposit via bank transfer or card. (Note: buying BTC in the Luno Exchange won't count).
  4. The £10/€15 will be credited to your account within a few minutes - and you can then sell & withdraw it back to your bank right away. You could also send it to another crypto wallet or exchange if you prefer, but you'll need to enable this feature first (go to profile - security - enable "send cryptocurrency." Sending will be enabled 24 hours later.)
  5. Tip: sell the BTC at the Luno Exchange for lower fees.
GBP withdrawals are free, SEPA (Euro) bank transfers cost €0.30.

Fun with low fee TXNs on Mainnet

Here's a 0.493 sat/vB TXN I put on mainnet today. You'll have to use the SoChain block explorer to see it though. I give it a 3% chance of getting confirmed, but we'll wait and see. The TXN is a donation to [email protected] since I use their seeder for my network herder.
So last month, I voiced the unpopular opinion that node operators should lower the minrelaytxfee setting to allow low-fee TXNs to propagate more freely throughout the network. Then I asked why miners weren't mining 0.999 sat/vB TXNs during idle periods since it should be more profitable than mining no TXNs at all. Finally I wrote a node herder to walk the network looking for node operators that were running minrelaytxfee below the default (1000 sat). After walking about 26% of the network, turns out about 5% of nodes are allowing low fee TXNs.
So in that vein of discussion, I decided to just sign some low-fee TXNs and send them to the 5% of nodes I found and see what happens. To my surprise it showed up on one of the 23 block explorers I tried after broadcasting it. Surprisingly, that comes out to about 5% of explorers accepting low fee TXNs as well. So hopefully 5% or so of the miners will confirm low fee TXNs. We'll see.
BTW, to do this, this is what I did.
  1. Pair my HW wallet to Electrum
  2. Use the paytomany Electrum API to craft a TXN below 1 sat/vB
  3. Import the TXN to sign in Electrum
  4. Ran a full node with minrelaytxfee set to 1 sat (0.001 sat/vB)
  5. Walked the network to find a good number of low-fee peers
  6. Use bitcoin addnode API to herd my node to the low-fee peers I discovered.
  7. Use bitcoin sendrawtransaction API to broadcast TXN
Wait and see if it can propagate to a miner and if a miner will accept it.
BTW, there is a PR to lower the minrelaytxfee in core, but it's dragged on for years. The setting was lowered about every year or so in the early days, but hasn't been touched for many years now.

Bitcoin tax questions (US) LedgerX options

Seasoned HODLer here with a question.
I’m expecting a big bonus in mid 2021 and I looked into call options for mid 2021 or end 2021 because I’m bullish. I signed up for an account on LedgerX but I’m unfamiliar with how bitcoin options are treated by the IRS.
Let’s say I exercise an option at expiry and I decide to transfer the ownership of the bitcoin to an address, is that a taxable event?
Scenario: I pay a $1500 premium for the option to buy 100 mini contracts at .01 btc each at a strikeprice of $50,000 with an expiry of December 31, 2021. Now let’s suppose S2F is right and bitcoin reaches $100,000 at expiry. I would then have a gain of $100,000 - $50,000 - $1,500 = $48,500. LedgerX would then give me the option to transfer ownership of the bitcoin once I fund my account. If just send that bitcoin to an address after funding the account for $50,000 is that event taxable? I get it’s taxable if I sell it. BUT is it taxable if I hodl?

[Offer] Free £15 (~16.5€) with InstaCoin - £10 from them and £5 from me - Almost Worldwide (Multiple Payouts Confirmed)

InstaCoin is a cryptocurrency platform that allows you to buy BTC via debit card, credit card, and bank transfer, as well as selling cryptocurrency and swapping with other cryptos.

Get £10 from InstaCoin - now available almost worldwide!

InstaCoin, a popular platform allowing you to instantly purchase bitcoin, is now available worldwide, with a few exceptions. This means more people can now take advantage of their referral offer, where you'll get £10 when you make your first bitcoin purchase of at least £100.
Steps:
  1. Sign up through my ref link (here's a non-ref link for no bonus). Don't be discouraged if it says you must be a UK resident to register. This is no longer true, so you can check the box anyway :) I think they just forgot to remove that statement.
  2. Verify your identity (Tier 2). This should take less than 5 minutes.
  3. Click Buy on the dashboard, and purchase at least £100 in Bitcoin. I strongly recommend entering your own BTC wallet address so you avoid extra fees. If you enter your own BTC wallet, they'll send the BTC straight there and your only fee will be £2.90 for buying Bitcoin.
  4. Right after the purchase, you'll get an email with a voucher for £10 in BTC. Click the link in the email, and they'll send the bonus to your own BTC wallet.
If you don't yet have a BTC wallet, you can get one for free at an exchange like Bitpanda, or Crypto.com. Both offer sign-up bonuses as well :)
