Forked from kobigurk/phase2-bn254.

This library is still under development.

WebAssembly how-to

Build wasm package using wasm-pack build --release -- --no-default-features --features wasm

this will generate ./pkg directory with wasm file and js bindings. After that you can use this package in your browser application like so:

async function main() {
    const phase2 = await import("./pkg/phase2.js")
    let data = await fetch('params')
    data = await data.arrayBuffer()
    data = new Uint8Array(data)
    console.log('Source params', data)
    const result = phase2.contribute(data)
    console.log('Updated params', result)
    // upload updated params



Security Warnings

This library does not make any guarantees about constant-time operations, memory access patterns, or resistance to side-channel attacks. To see possible measures to protect the secret data generated during the ceremony, see the [Powers of Tau readme][../powersoftau/README.md].
