# Rococo Testnet Setup Guide

## Tools setup

Refer to this [guide](https://github.com/paritytech/polkadot#build-from-source)

## Validators

3 validators are required, namely `Alice`, `Bob`, `Charlie`.

### Build validators

Fetch [polkadot repo](https://github.com/paritytech/polkadot), check out `rococo-v1` branch and commit `9bc8915acd5507a77737371fdd892bb1f6a8db22`.

Go to the root of repo, Build polkadot by:

cargo build --release --features=real-overseer

After build success, export raw chain spec:

./target/release/polkadot build-spec --chain=rococo-local --raw > /testnet-path/rococo-local.json

### Run validators

Run 3 validtors. Note to replace `path-to-polkadot-repo` and `testnet-path` with the directories in your local environment.

Alice:

RUST_LOG=candidate_backing=trace /path-to-polkadot-repo/target/release/polkadot \
        --alice \
        --chain=/testnet-path/rococo-local.json \
        --rpc-methods=unsafe \
        --ws-port=9944 \
        --port=30444 \
        --wasm-execution=Compiled \
        --validator \
        --execution=wasm \
        -lsync=info \
        --base-path=alice

Bob:

/path-to-polkadot-repo/target/release/polkadot \
        --bob \
        --chain=/testnet-path/rococo-local.json \
        --rpc-methods=unsafe \
        --ws-port=9955 \
        --port=30555 \
        --wasm-execution=Compiled \
        --validator \
        --execution=native \
        -lsync=info \
        --base-path=bob

Charlie:

/path-to-polkadot-repo/target/release/polkadot \
        --charlie \
        --chain=/testnet-path/rococo-local.json \
        --rpc-methods=unsafe \
        --ws-port=9966 \
        --port=30666 \
        --wasm-execution=Compiled \
        --validator \
        --execution=wasm \
        -lsync=info \
        --base-path=charlie

## Acala Collator

Fetch acala repo, check out `sw/rococo-v1` branch.

Go to the root of repo, build with command:

cargo build --release

Run Acala collator. Note to replace `path-to-acala-repo`, `testnet-path`.

RUST_LOG=cumulus-collator=trace /path-to-acala-repo/target/release/acala \
      --collator \
      --chain=dev \
      --ws-port=9977 \
      --port=30777 \
      --rpc-methods=unsafe \
      --rpc-cors=all \
      --wasm-execution=Compiled \
      --parachain-id=666 \
      --execution=native \
      -lsync=debug \
      --base-path=acala \
      -- \
      --chain=/testnet-path/rococo-local.json \
      --port 30337 \
      --wasm-execution=Compiled

## Laminar Collator

Fetch laminar repo, check out `sw/rococo-v1` branch.

Go to the root of repo, build with command:

cargo build --release

Run Laminar collator. Note to replace `path-to-laminar-repo`, `testnet-path`.

RUST_LOG=cumulus-collator=trace /path-to-laminar-repo/target/release/laminar \
      --validator \
      --chain=dev \
      --ws-port=9988 \
      --port=30888 \
      --rpc-methods=unsafe \
      --rpc-cors=all \
      --wasm-execution=Compiled \
      --parachain-id=777 \
      --execution=Native \
      --base-path=laminar \
      -- \
      --chain=/testnet-path/rococo-local.json \
      --port 30338 \
      --wasm-execution=Compiled
