Rust (WASM) port of Eigentrust

This is a Rust port of the EigenTrust algorithm, originally implemented in Go. The project includes both server and client implementations designed to run natively as well as in a WebAssembly environment for browser compatibility.

Live Demo

https://eigentrust.web.app

Test

cargo test

Build WASM for web

wasm-pack build --target web

wasm-pack build --target web --release

python3 -m http.server

http://localhost:8000/index.html

Call from browser environment

import init, { run } from './pkg/eigentrust_js.js'
    async function main() {
        await init()
        
        console.time("eigentrust job")
        const result = run(localtrustBytes, pretrustBytes, 0.5)
        console.timeEnd("eigentrust job")
        console.log({result})
    }

main()

Run OS native

cargo run ./example/localtrust.csv ./example/pretrust2.csv

Build

cargo build --release
./target/release/eigentrust-rs ./tmp/trust-db.csv ./tmp/seed-db.csv
