Preparation Before Installation

Funding Your Wallet

You will need a new EVM wallet with test ETH tokens on the Sepolia network. Use the faucet, but note that the required amount is currently quite high due to the validator registration quota (~50 ETH).

RPC

You need an Ethereum Sepolia RPC and Beacon endpoint for the node to work. It is recommended to deploy your own service or buy a private RPC (I can provide one if needed).

Node Installation

Open your terminal and connect to your server via SSH.

Update system components and install required utilities:

sudo apt-get update && sudo apt-get upgrade -y

sudo apt install curl ufw iptables build-essential git wget lz4 jq make gcc nano automake autoconf tmux htop nvme-cli libgbm1 pkg-config libssl-dev libleveldb-dev tar clang bsdmainutils ncdu unzip libleveldb-dev  -y

Install Aztec tools, press y twice when prompted:
```
bash -i <(curl -s https://install.aztec.network/)
```
Update your environment and check the tools:
```
source ~/.bash_profile
```
```
aztec-up alpha-testnet
```

Create files to manage your node: Create a directory and enter it:

mkdir -p aztec && cd aztec

Create a launch file:

nano docker-compose.yml

Paste the following snippet, change ports if needed:

services:
  node:
    image: aztecprotocol/aztec:0.87.2
    environment:
      ETHEREUM_HOSTS: "${ETHEREUM_HOSTS}"
      L1_CONSENSUS_HOST_URLS: "${L1_CONSENSUS_HOST_URLS}"
      DATA_DIRECTORY: /data
      VALIDATOR_PRIVATE_KEY: "${VALIDATOR_PRIVATE_KEY}"
      P2P_IP: "${P2P_IP}"
      PXE_PORT: "${PXE_PORT}"
      TXE_PORT: "${TXE_PORT}"
      LOG_LEVEL: debug
    entrypoint: >
      sh -c 'node --no-warnings /usr/src/yarn-project/aztec/dest/bin/index.js start --network alpha-testnet start --node --archiver --sequencer'
    volumes:
      - /home/aztec/node:/data
    ports:
      - 40400:40400/tcp
      - 40400:40400/udp
      - 8080:8080

Save with CTRL+S, CTRL+X

Create a configuration file:

nano .env

Paste and fill in your values:

L1_SEPOLIA_RPC_URL=<Your_Sepolia_RPC_URL>
L1_BEACON_URLS=<Your_BEACON_URL>
VALIDATOR_PRIVATE_KEY=<Your_Privat_Key_with_0x>
P2P_IP=<Your_Server_IP>

Save with CTRL+S, CTRL+X

Start the operator (node) and check logs:

docker-compose up --build -d
docker-compose logs -f --tail 20

Getting the `Apprentice` Role in Discord

After your node syncs, get the latest synced block number:

curl -s -X POST -H 'Content-Type: application/json' \
-d '{"jsonrpc":"2.0","method":"node_getL2Tips","params":[],"id":67}' \
http://localhost:8080 | jq -r ".result.proven.number"

In the command below, replace <BLOCK_NUMBER> with your block number and port 8080 if you changed it:

curl -s -X POST -H 'Content-Type: application/json' \
-d '{"jsonrpc":"2.0","method":"node_getArchiveSiblingPath","params":["<BLOCK_NUMBER>","<BLOCK_NUMBER>"],"id":67}' \
http://localhost:8080 | jq -r ".result"

In the project Discord, in the #operators | start-here channel, use the /operator start command and provide the required data.

Validator Registration

You need to send a transaction at a specific time and hope for luck, as the number of applicants is growing and the daily quota is only 5.

Replace the data and run the command:

aztec add-l1-validator \
--l1-rpc-urls <Your_Sepolia_RPC_URL> \
--private-key <Your_Private_Key> \
--attester <Your_Wallet_Address> \
--proposer-eoa <Your_Wallet_Address> \
--staking-asset-handler 0xF739D03e98e23A7B65940848aBA8921fF3bAc4b2 \
--l1-chain-id 11155111
