bch-merit-lib
This library is used to compute 'merit' of a Bitcoin Cash (BCH) address, based on PSF tokens held by that address.
Merit = Number of PSF tokens X age of PSF tokens (in days)
This library walks the UTXO DAG of the address in order to apply the equation above to each UTXO, then aggregates those calculations into a single number.
Note: This library behaves differently when using the 'rest-api' (bch-api, bch-js, fullstack.cash) interface vs the 'consumer-api' (web3, free-bch.fullstack.cash). The reason is that the rest-api interface will work with the complete transaction history of an address, whereas the consumer-api interface will clip transaction history at 100 entries. If the merit calculation expands more than 100 tx entries in the addresses history, then older parents won't be counted.
Installation
npm install --save-exact bch-merit-lib
Usage
// Instantiate minimal-slp-wallet
const BchWallet = require('minimal-slp-wallet/index')
wallet = new BchWallet(undefined, { noUpdate: true, interface: 'consumer-api' })
// Instantiate the Merit library
const Merit = require('bch-merit-lib/index')
merit = new Merit({ wallet })
