Opacity Local

This repository contains the configuration and setup for running the Opacity AVS (Actively Validated Service) infrastructure using Docker Compose.

Prerequisites

• Docker
• Docker Compose

Setup

1. Clone this repository:

   git clone https://github.com/OpacityLabs/opacity-avs-node.git
   cd opacity-avs-node
   

2. Create a .env file in the root directory and add the following environment variables:

   cp example.env .env
   

   Make sure you have filled in all the variables

    DELEGATION_MANAGER_ADDRESS= # Depends on the desired ENV 
    STRATEGY_MANAGER_ADDRESS=
    REGISTRY_COORDINATOR_ADDRESS=
    LST_CONTRACT_ADDRESS=
    LST_STRATEGY_ADDRESS=
    FORK_URL=
    RPC_URL=http://ethereum:8545
    WEBSOCKET_RPC_URL=ws://ethereum:8545
    ENVIRONMENT= # Depends on the desired ENV 
    MAX_OPERATOR_RETRY_ATTEMPTS=10
    SERVER_PRIVATE_KEY= 
   

3. Build and start the services:

   docker-compose up --build
   

Note that the nodes and node selector only start up after the eigenlayer setup container has exited

Services

The Docker Compose setup includes the following services:

1. ethereum: An Ethereum node for local development and testing.
2. eigenlayer: Sets up EigenLayer and registers operators.
3. nodeselector: A node selector service for the Opacity AVS.
4. node1, node2, node3: Opacity AVS nodes.

Configuration

• The docker/eigenlayer/register.sh script creates test accounts and registers them as operators.
• Node configurations are stored in .nodes/configs/.
• Operator keys are stored in .nodes/operator_keys/.

Accessing the Services

• Ethereum RPC: http://localhost:8545
• Node Selector: http://localhost:8080
• Opacity AVS Nodes:
  • Node 1 MPC-TLS: http://localhost:7047
  • Node 1 BLS-Attestation: http://localhost:6047
  • Node 2 MPC-TLS: http://localhost:7048
  • Node 2 BLS-Attestation: http://localhost:6048
  • Node 3 MPC-TLS: http://localhost:7049
  • Node 3 BLS-Attestation: http://localhost:6049

Notes

• The .gitignore file is set up to exclude sensitive information like operator keys and test account configs.
• Make sure to keep your .env file secure and do not commit it to version control.

For more detailed information about each component, refer to the individual Dockerfile and configuration files in the docker/ directory.
