OpenChat

https://oc.app

OpenChat is a fully featured chat application running end-to-end on the Internet Computer blockchain.

Prerequisites

DFX 0.23.0

To install, run DFX_VERSION=0.23.0 sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"

Rust

To install, run curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

NPM

Download from https://nodejs.org/en/download

Testing locally

Start DFX using dfx start

To install all the necessary canisters (OpenChat and NNS) run ./scripts/deploy-local.sh

To run the website run npm --prefix frontend run dev

To upgrade a canister run ./scripts/upgrade-canister-local.sh <DFX_IDENTITY_NAME> <CANISTER_NAME> <VERSION> (eg. ./scripts/upgrade-canister-local.sh default user 1.0.0)

To start again with a fresh install, stop DFX, then run rm -rf .dfx, then start from the top of these instructions again.

Deterministic builds

We need builds to be deterministic so that code running inside a canister can be verified by comparing the wasm hash locally with the wasm hash exposed by the IC.

You can build the OpenChat canister wasms by running ./scripts/docker-build-all-wasms.sh
