Boost POW Javascript Library

Boost Proof of Work Protocol https://boostpow.com

Boost is a new type of content ranking system that enables users to increase the amount of energy required to mine or process their content. Users will boost their post as a way to signal to the network that they believe their information is valuable. Boosted posts will appear in the boost feed – ordered by the amount of energy requested for their information.

A Boost Pow String (also called "Boost Header") consist of an 80 byte string that is encoded identically to a Bitcoin Block Header. The string is valid if the hash256 of the string is less than the target difficulty specified inside the string.

We can objectively order content of Boost Pow Strings from most to least energy (difficulty) in a way that is self-evident and provable. The world's first provably fair content ranking system powered by native Bitcoin Proof of Work.

Boost Pow String:

010000009500c43a25c624520b5100adf82cb9f9da72fd2447a496bc600b0000000000006cd862370395dedf1da2841ccda0fc489e3039de5f1ccddef0e834991a65600ea6c8cb4db3936a1ae3143991

And its hash256 is: 0000000000002917ed80650c6174aac8dfc46f5fe36480aaef682ff6cd83c3ca

Sample code to verify Boost Pow String:

// Validate a Boost Pow String
// Underneath bsv.js validates the string *exactly* like a Bitcoin Block Header
const powString = boost.BoostPowString.fromString('010000009500c43a25c624520b5100adf82cb9f9da72fd2447a496bc600b0000000000006cd862370395dedf1da2841ccda0fc489e3039de5f1ccddef0e834991a65600ea6c8cb4db3936a1ae3143991');
// Print out the decoded string
console.log(powString.toObject());
/*
{
    hash: '0000000086915e291fe43f10bdd8232f65e6eb64628bbb4d128be3836c21b6cc',
    content: '00000000000000000000000000000000000000000048656c6c6f20776f726c64',
    bits: 486604799,
    difficulty: 1,
    metadataHash: "acd8278e84b037c47565df65a981d72fb09be5262e8783d4cf4e42633615962a",
    time: 1305200806,
    nonce: 3698479534,
    category: 1,
}

MoneyButton, Relay, TwetchPay Integration

Easily integrate MoneyButton, Relay, and TwetchPay

Consult the respective documentation for additional details. All services support the 'outputs' format presented below for easy integration.

const boost = require('boostpow');
// Create a Boost request with your data
const boostJob = boost.BoostPowJob.fromObject({
  content: Buffer.from('hello world', 'utf8').toString('hex'),
  diff: 1, // Minimum '1'. Specifies how much hashrate. 1 = difficulty of Bitcoin Genesis (7 MH/second)
  category: Buffer.from('B', 'utf8').toString('hex'),
  additionalData: Buffer.from(`{ "foo": 1234, "metadata": "hello"}`, 'utf8').toString('hex'),
  userNonce: Buffer.from(Math.random(999999999), 'utf8').toString('hex'),
  tag: Buffer.from('funny-animals', 'utf8').toString('hex'),
});
// Construct a MoneyButton or Relay Output
const boostOutputs = [{
  script: boostJob.toASM(),
  amount: boostJob.difficulty * 0.0001, // Charge a fee for the Boost. In future this will be a feeQuote system. Higher payout the more likely a miner will mine the boost relativity to the diff.
  currency: "BSV"
}];

// Now you can populate MoneyButton, Relay or TwetchPay with the outputs:
twetchPay.pay({
  label: 'Boost Content',
  outputs: boostOutputs,
  onPayment: async (e) => {
    // submit to the JSON API for immediate indexing
    // In the future a planaria will pick it up automatically on-chain, for now submit the rawtx
  }
});
