Setup

Building components

# Clone the repo.

git clone git@github.com:uqbar-dao/uqbar.git


# Get some stuff so we can build wasm.

cd uqbar
cargo install wasm-tools
rustup install nightly
rustup target add wasm32-wasi
rustup target add wasm32-wasi --toolchain nightly
cargo install cargo-wasi
cargo install --git https://github.com/bytecodealliance/cargo-component --locked cargo-component


# Initialize submodules, in particular the register app

git submodule update --init --recursive
# Build the register app
cd src/register && ./build_all.sh && cd ../..


# Build the runtime, along with a number of booted-at-startup WASM modules including terminal and key_value
# OPTIONAL: --release flag

cargo +nightly build --release

Boot

If you do not receive QNS updates in terminal, it's a sign that the default public-access RPC endpoint is rate-limiting or blocking you. Get an eth-sepolia-rpc API key and pass that as an argument. You can get one for free at alchemy.com.

Also, make sure not to use the same home directory for two nodes at once! You can use any name for the home directory.

cargo +nightly run --release -- --home home --rpc wss://eth-sepolia.g.alchemy.com/v2/<your-api-key>

On boot you will be prompted to navigate to localhost:8080. Make sure your eth wallet is connected to the Sepolia test network. Login should be very straightforward, just submit the transactions and follow the flow.
