Internet Speed 25 Mbps Upload / Download

Note

A 4-core CPU, 8 GiB RAM, and 25 GiB storage suffice for earning the Apprentice role, but meet recommended specs for long-term stability.

⚙️ Prerequisites

  • Ubuntu System: Script requires Ubuntu.
  • Sepolia Ethereum RPC: Get from Alchemy.
  • Sepolia Beacon RPC: Obtain from Chainstack.
  • EVM Wallet: Fund with 2.5 Sepolia ETH for validator registration.
  • sudo Privileges: Needed for package installation and firewall setup.

Important

Free RPC services may hit request limits. Switch providers or upgrade if limited.

📥 Installation

  1. Clone and Run the Script: 
    cd
rm -r Aztec
git clone https://github.com/cryptoneth/Aztec.git
cd Aztec
chmod +x aztec.sh
./aztec.sh

**Follow Prompts:

Step 1 - 3: ... !

Step 4: Enter Sepolia Ethereum RPC, Beacon RPC, Ethereum private key, public address (with 2.5 Sepolia ETH), and server IP.

Step 7: Confirm earning the Apprentice role on Discord.

you can see your node running

screen -x aztec

Press Crtl + A + D to quit

Get Role Go to the discord channel :operators| start-here and follow the prompts, You can continue the guide with my commands if you need help.

Step 1: Get the latest proven 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"
  • Save this block number for the next steps
  • Example output: 20905

Step 2: Generate your sync proof

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"
  • Replace 2x BLOCK_NUMBER with your number

Step 3: Register with Discord

  • Type the following command in this Discord server: /operator start
  • After typing the command, Discord will display option fields that look like this:
  • address: Your validator address (Ethereum Address)
  • block-number: Block number for verification (Block number from Step 1)
  • proof: Your sync proof (base64 string from Step 2)

Then you'll get your Apprentice Role

Register Validator

aztec add-l1-validator \
  --l1-rpc-urls RPC_URL \
  --private-key your-private-key \
  --attester your-validator-address \
  --proposer-eoa your-validator-address \
  --staking-asset-handler 0xF739D03e98e23A7B65940848aBA8921fF3bAc4b2 \
  --l1-chain-id 11155111

Replace RPC_URL, your-validator-address & 2x your-validator-address, then proceed

##Update your node :

aztec-up alpha-testnet

Error: ERROR: world-state:block_stream Error processing block stream: Error: Obtained L1 to L2 messages failed to be hashed to the block inHash

  • Stop node with Ctrl+C.
  • Delete node data:
rm -r /root/.aztec/alpha-testnet
  • Re-run the node using run command.
