KZG Ceremony Frontend

Work in Progress

This React App is a graphic interface to interact with the Ethereum KZG Ceremony. Participants can checkout the website at https://kzg-ceremony.party/

Start

To start this app execute the following steps:

1. Run the sequencer app from https://github.com/ethereum/kzg-ceremony-sequencer. It is assumed that the assigned port is 3000 and that our react app would use port 3001. You can set PORT env variable with a specific port for React.

2. Setup environment variables:

   Ubuntu: export REACT_APP_API_ROOT=http://localhost:3000 Windows (Powershell): $env:REACT_APP_API_ROOT="http://localhost:3000"

   Ubuntu: export REACT_APP_SIGNIN_REDIRECT_URL=http://localhost:3001/signin Windows (Powershell): $env:REACT_APP_SIGNIN_REDIRECT_URL="http://localhost:3001/signin"

3. Install dependencies: yarn install

4. Copy the /wasm directory from the wrapper library in the public/ directory. Most of the times the wasm-worker.js will not change

5. Start application: yarn start

Note: In case you get a crossOriginIsolated error when running the contribution function in the web worker, it might be caused by this known-and-soon-to-be-solved issue. You would need to change the token in the http-equiv="origin-trial" meta tag in index,html to:
