libzkbob-rs-wasm-web

libzkbob-rs-wasm

Wasm/JavaScript version of libzkbob-rs.

Install

Bundler version: npm i -S libzkbob-rs-wasm-bundler or nodejs version: npm i -S libzkbob-rs-wasm-nodejs

Configuration

Webpack 5

When using the bundler version, make sure that the experiments.asyncWebAssembly is set to true and there is no import to require transformation happening before webpack has a chance to process your code.

For example, in your tsconfig.json set this option so that the typescript compiler does not transform your imports compilerOptions.module = "es2020"

  experiments: {
    asyncWebAssembly: true,
  }

Usage

import { UserAccount, State } from 'libzkbob-rs-wasm-bundler';

const state = await State.init("any user identifier");
const account = new UserAccount(spendingKey, state);

const address = account.generateAddress();
const mergeTx = await account.createTx([{ to: address, amount: "0"}], blockchainData);

const params = Params.fromBinary(serializedParameters);
const proof = Proof.tx(params, mergeTx.public, mergeTx.secret);
