Sequencer Node Simple Installation

Prerequisites

Ensure that you meet the hardware requirements to run the Aztec sequencer node. A computer running Linux or MacOS with the following specifictions:

  • CPU: 8-cores
  • RAM: 16 GiB
  • Storage: 1 TB SSD

A Network connection of at least 25 Mbps up/down.

Installation

Step 1 - Docker Installation

Run the following command to uninstall all conflicting packages:

for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

Set up Docker’s apt repository.

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
 
# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

Install the Docker packages.

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

Step 2 - Config Docker Compose

Copy docker compose configuration below and adjust variable according to your account

name: aztec-node
services:
  node:
    image: aztecprotocol/aztec:alpha-testnet
    environment:
      ETHEREUM_HOSTS: $EVM_API_RPC
      L1_CONSENSUS_HOST_URLS: $BEACON_API_RPC
      VALIDATOR_PRIVATE_KEY: $VALIDATOR_PK
      COINBASE: $VALIDATOR_ADDRESS
      P2P_IP: $SERVER_IP
      DATA_DIRECTORY: /data
    entrypoint: >
      sh -c 'node --no-warnings /usr/src/yarn-project/aztec/dest/bin/index.js start --network alpha-testnet start --node --archiver --sequencer'
    ports:
      - 40400:40400/tcp
      - 40400:40400/udp
      - 8080:8080
    volumes:
      - ~/.aztec/alpha-testnet/data:/data

Details

  • EVM_API_RPC : The HTTP-RPC endpoint for your execution node, obtained from RPC Provider (Ankr, Infura, D-RPC, Alchemy) or Running your own geth node.
  • BEACON_API_RPC : The REST API endpoint for your consensus node, obtained from RPC Provider (D-RPC, Ankr) or Running your own consensus node.
  • VALIDATOR_PK : An Ethereum private key for your sequencer.
  • VALIDATOR_ADDRESS : The public address derived from your VALIDATOR_PK.
  • SERVER_IP : Your server IP, obtain it using curl -s ifconfig.co/ip

You could run your own geth & consensus node using the guide from us

Step 3 - Run Docker Compose

Execute the command below to run your node via docker compose

docker compose up -d

Step 4 - Monitor Your Node

Look for your node logs and monitor it carefully using the command below

docker compose logs --tail 100 -f

Check Block Number & Proof

To obtain recent block number & its proof you can use the command below

RPC="http://127.0.0.1:8080";
block=$(curl -s -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","method":"node_getL2Tips","params":[],"id":67}' $RPC | jq -r .result.proven.number); 
proof=$(curl -s -H 'Content-Type: application/json' -d "{\"jsonrpc\":\"2.0\",\"method\":\"node_getArchiveSiblingPath\",\"params\":[\"$block\",\"$block\"],\"id\":67}" $RPC | jq -r .result); 
echo "Block Number: $block"; 
echo "Proof: $proof";

Validator Registration

Run the command below to install aztec tools

sudo chown -R $USER:$USER ~/.aztec
bash -i <(curl -s https://install.aztec.network)
echo 'export PATH=$PATH:~/.aztec/bin' >> ~/.profile
source ~/.profile

To register your sequencer node as a validator you can use the command below

aztec add-l1-validator \
  --l1-rpc-urls $EVM_API_RPC \
  --private-key $VALIDATOR_PRIVATE_KEY \
  --attester $VALIDATOR_ADDRESS \
  --proposer-eoa $VALIDATOR_ADDRESS \
  --staking-asset-handler 0xF739D03e98e23A7B65940848aBA8921fF3bAc4b2 \
  --l1-chain-id 11155111

Delete Node

To delete node & data you can run the command below

docker compose down
sudo rm -r ~/.aztec
