# Usando Releases (binário)

- https://github.com/paritytech/polkadot/releases

mkdir ~/polkadot
cd ~/polkadot

RELEASE=v0.9.11

wget https://github.com/paritytech/polkadot/releases/download/$RELEASE/polkadot

chmod a+x polkadot

./polkadot \
    --name "PortugueseValidator" \
    --validator \
    --wasm-execution Compiled \
    --telemetry-url 'wss://telemetry-backend.w3f.community/submit 1'

# Usando Docker

### Instalando o Docker:

- https://docs.docker.com/engine/install/

### DockerHub Images:

- https://hub.docker.com/r/parity/polkadot/tags

### Iniciando um Container com um Polkadot Validator Node:

docker pull parity/polkadot

POLKADOT_STORAGE=~/.local/share/polkadot/docker

mkdir -p $POLKADOT_STORAGE

docker run \
	--name POLKADOT_VALIDATOR \
	--network host \
	-v $POLKADOT_STORAGE:/polkadot/.local/share/polkadot \
	-dti parity/polkadot:latest \
		--name "PortugueseValidator" \
		--validator \
		--wasm-execution Compiled \
		--telemetry-url 'wss://telemetry-backend.w3f.community/submit 1'

### Iniciando um Container com um Kusama Validator Node:

docker pull parity/polkadot

KUSAMA_STORAGE=~/.local/share/kusama/docker

mkdir -p $KUSAMA_STORAGE

docker run \
	--name KUSAMA_VALIDATOR \
	--network host \
	-v $KUSAMA_STORAGE:/polkadot/.local/share/polkadot \
	-dti parity/polkadot:latest \
		--name "PortugueseValidator" \
		--chain kusama \
		--validator \
		--wasm-execution Compiled \
		--unsafe-pruning \
		--pruning 1000 \
		--telemetry-url 'wss://telemetry-backend.w3f.community/submit 1'

### Bonding DOT/KSM

- https://wiki.polkadot.network/docs/maintain-guides-how-to-validate-polkadot#bond-dot

### Demo (Westend):

- Criar duas Accounts:
- Stash (Cold Wallet)
- Controller (Hot Wallet)
- Transferir `WND` para ambas Accounts:
- faucet: [#westend_faucet:matrix.org](https://matrix.to/#/#westend_faucet:matrix.org)
- [polkadot.js.org@parity](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fwestend-rpc.polkadot.io#/staking/actions)
- [polkadot.js.org@onfinality](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fwestend.api.onfinality.io%2Fpublic-ws#/staking/actions)

### Generating Session Key:

curl \
    -H "Content-Type: application/json" \
    -d '{"id":1, "jsonrpc":"2.0", "method": "author_rotateKeys", "params":[]}' \
    http://localhost:9933
