Baseline

@baseline-protocol/baseline

The core baseline package provides unified access to internal integration middleware interfaces for systems of record.

Installation

npm install @baseline-protocol/baseline(npm package soon to be published)

Building

You can build the package locally with npm run build.

Testing

Run the local test suite with npm test.

Baseline JSON-RPC Module

An initial set of JSON-RPC methods have been defined for inclusion in the specification. These methods allow easy interaction with on-chain shield contracts (which contain merkle-tree fragments) and maintain full merkle-trees (along with metadata) in local off-chain storage.

Method	Params	Description
baseline_getCommit	address, commitIndex	Retrieve a single commit from a tree at the given shield contract address
baseline_getCommits	address, startIndex, count	Retrieve multiple commits from a tree at the given shield contract address
baseline_getRoot	address	Retrieve the root of a tree at the given shield contract address
baseline_getProof	address, commitIndex	Retrieve the membership proof for the given commit index
baseline_getTracked		Retrieve a list of the shield contract addresses being tracked and persisted
baseline_verifyAndPush	sender, address, proof, publicInputs, commit	Inserts a single commit in a tree for a given shield contract address
baseline_track	address	Initialize a merkle tree database for the given shield contract address
baseline_untrack	address	Remove event listeners for a given shield contract address
baseline_verify	address, value, siblings	Verify a proof for a given root and commit value
