This is a JavaScript library that is packaged with Browserify, to make it accessible to both browser-based and node.js-based JavaScript apps. It allows Bitcoin Cash (BCH) wallets to create, read, and update tokens that have both mutable (changeable) and immutable (unchangeable) data. Data is stored off-chain, and available via IPFS.
This library implements this PS002 specification for token mutable data. It follows a series of pointers on the Bitcoin Cash blockchain to retrieve a JSON file from the IPFS network. This is a way to track changing data associated with a token. It's a way for video game characters, supply chain items, and other unique changing assets to be represented by a token. This library is an extension of the Cash Stack.
Here are different ways to consume this library in your app, depending on the environment you are using.
<script src="https://unpkg.com/slp-mutable-data"></script>
npm install --save slp-mutable-data
// module import
import SlpMutableData from 'slp-mutable-data'
// nodejs modules
const SlpMutableData = require('slp-mutable-data/index')Examples are provided in the examples directory:
- Create Data by uploading a JSON object to Filecoin via web3.storage.
- Create a Token with both mutable and immutable data.
- Update Mutable Data.
- Get Token Data.
