TF Grid db on substrate

Installation

You will need a specific version of rust nightly in order to compile:

rustup install nightly

Wasm toolchain:

rustup target add wasm32-unknown-unknown --toolchain nightly

Now you can build.

cd substrate-node
make build-debug

This will build the node binary in release mode, once built you can execute it by doing following:

./target/release/susbtrate --dev --tmp --ws-external

You need the ws-external flag in order to connect from a zos node to substrate in a local setup.

You can use the client to interact with the chain, read more

If you want to query the data inside the blockchain with graphql you can set this up locally.

cd graphql

yarn

yarn build

yarn db:up
yarn db:prepare
yarn db:migrate
yarn db:init

docker-compose up

Now browse to localhost:4000/graphql

Example query:

query {
    entities(limit: 5) {
        name
    }
}
