JS-JSONLD-MERKLIZATION

@iden3/js-jsonld-merklization is a library for merklizing JSON-LD documents in JavaScript. Merklization is a process that creates a Merkle tree of a JSON-LD document, which allows for efficient verification of data integrity and authenticity.

This library uses jsonld.js to serialize JSON-LD documents into a canonical form, which is then hashed using Poseidon hash. The resulting hashes are combined into a Merkle tree, which can be used to verify the integrity of the original JSON-LD document.

To use this library, you can install it via npm:

npm install @iden3/js-jsonld-merklization

Alternatively, you can include it in your project via a CDN:
