Run a docker test node

1. Build and run your own docker image using docker-compose file. Build time could take up to 60 min.

   git clone https://github.com/randombishop/wika_node.git
   docker-compose -p my_wika_node -f docker-compose.yaml up --build

2. Pull and run latest image of wika test node using docker-compose file

   git clone https://github.com/randombishop/wika_node.git
   docker-compose -p my_wika_node -f docker-compose.yaml up

Install locally

1. Follow substrate documentation to install dependencies (do #1 only) https://substrate.dev/docs/en/knowledgebase/getting-started/

2. For example, in apt world

   sudo apt update
   sudo apt install -y git clang curl libssl-dev llvm libudev-dev

3. Install and setup rust

   curl https://sh.rustup.rs -sSf | sh
   source ~/.cargo/env
   rustup default stable
   rustup update
   rustup update nightly
   rustup target add wasm32-unknown-unknown --toolchain nightly

4. Git clone substrate

   Current substrate repo compatible tag is monthly-2021-08

   git clone https://github.com/paritytech/substrate.git
   cd substrate
   git checkout monthly-2021-08
   cd ..

5. Git clone wika-node side by side with substrate

   git clone https://github.com/randombishop/wika_node.git

6. Compile it Should take 20 minutes to 1 hour depending on your number of CPUs, also note that a minimum of 4Gb of RAM is required here.

   cd wika_node
   cargo build
   or
   cargo build --release

Run locally for development

./target/debug/wika-node --tmp --dev -lOWNERS=debug -lLIKE=debug
or
./target/release/wika-node --tmp --dev -lOWNERS=debug -lLIKE=debug

Enabling offchain worker with Alice as a verifier

1. Add Alice's private keys to the owner pallet.

   curl http://localhost:9933 -H "Content-Type:application/json;charset=utf-8" -d "@./dev_keys/alice_ownr.json"

2. Use the owners pallet addVerifier transaction to add Alice public key as a verifier.

Generating a chain spec file

(https://substrate.dev/docs/en/tutorials/start-a-private-network/customspec)

.target/release/wika-node  --chain test build-spec > specfile.json

Start a test node and join test net

(https://substrate.dev/docs/en/tutorials/start-a-private-network/customchain)

    --public-addr /ip4/x.x.x.x \
    --base-path /var/db_wika/test1 \
    --telemetry-url 'wss://telemetry.polkadot.io/submit/ 0' \
    --name xyz1 \
    --chain specfile.json \
    --bootnodes /ip4/z.z.z.z/tcp/30334/p2p/xyz
