Opacity AVS Node

For support contact @EulerLagrange217 on telegram

Introduction

The Opacity node must be run with a Intel SGX with SGX2 enabled. If you want to use a cloud provider, please use one of these:

• Azure (https://learn.microsoft.com/en-us/azure/confidential-computing/quick-create-portal)
• OVH (https://help.ovhcloud.com/csm/en-dedicated-servers-intel-sgx?id=kb_article_view&sysparm_article=KB0044005)

We recommend you use Ubuntu 22.04

We DO NOT support AWS Enclaves!

Check SGX

First we should check you are on a valid SGX machine.

Head over to https://support.fortanix.com/hc/en-us/articles/4414753648788-SGX-Detect-Tool and download the binary for your operating system.

Ubuntu 22.04: wget https://download.fortanix.com/sgx-detect/ubuntu22.04/sgx-detect?_gl=1*1j4w6dh*_gcl_au*MTM1MDY4MDQ2NS4xNzE4ODUwMTk1 -O sgx-detect chmod +x sgx-detect sudo ./sgx-detect

You should see:

If you see any red on the output, please contact @EulerLagrange217 on telegram

Register Node Operator with EigenLayer

The following is not Opacity specific but for EigenLayer. We will be summarizing the following verboase guide: https://docs.eigenlayer.xyz/eigenlayer/operator-guides/operator-installation

1. Install EigenLayer-CLI

For Ubuntu 22.04: install-eigenlayer-cli

2. Create ECDSA and BLS keys

make generate-keys

OR

eigenlayer operator keys create --key-type ecdsa opacity eigenlayer operator keys create --key-type bls opacity

To check if you did it right you can run:

make list-keys

3. Fund ECDSA Wallet with testnet ETH

We need to load your operator wallet with some holesky eth to submit transactions. See: https://docs.eigenlayer.xyz/eigenlayer/restaking-guides/restaking-user-guide/testnet/obtaining-testnet-eth-and-liquid-staking-tokens-lsts

4. Use some Holesky eth to get holesky stETH:

https://stake-holesky.testnet.fi/

5. Operator config

We need to generate some metadata so eigenlayer can show you nicely in their UI.

I would recommend forking this repo: https://github.com/Hmac512/eigenpod and changing the values to what you want.

Run:

eigenlayer operator config create

Say yes to populating the config

Enter your operator address: 0xfe8463ca0a9b436fdc5f75709ad5a43961802d68 Enter your earnings address (default to your operator address): 0xfe8463ca0a9b436fdc5f75709ad5a43961802d68 Enter your ETH rpc url: https://ethereum-holesky.publicnode.com Select your network: holesky Select your signer type: local_keystore Enter your ecdsa key path: /home/ubuntu/.eigenlayer/operator_keys/opacity.ecdsa.key.json

This will generate a operator.yaml file that should look like:

operator: address: 0xFE8463CA0A9b436FdC5f75709AD5a43961802d68 earnings_receiver_address: 0xFE8463CA0A9b436FdC5f75709AD5a43961802d68 delegation_approver_address: "0x0000000000000000000000000000000000000000" staker_opt_out_window_blocks: 0 metadata_url: "https://raw.githubusercontent.com/Hmac512/eigenpod/main/metadata.json?" el_delegation_manager_address: 0xA44151489861Fe9e3055d95adC98FbD462B948e7 eth_rpc_url: https://ethereum-holesky.publicnode.com private_key_store_path: /home/ubuntu/.eigenlayer/operator_keys/opacity.ecdsa.key.json signer_type: local_keystore chain_id: 17000 fireblocks: api_key: "" secret_key: "" base_url: "" vault_account_name: "" secret_storage_type: "" aws_region: "" timeout: 0 web3: url: ""

Remember to fill out the metadata_url to your forked repo.

Make a backup of your operator.yaml for convenience

6. Register Node Operator

run:

make register-eigen-operator OR eigenlayer operator register operator.yaml
