Obol Distributed Validator Blueprint 🌐

A Tangle Blueprint for running a Obol Distributed Validator Cluster

📚 Overview

This Tangle Blueprint provides a specification for running a group Obol Distributed Validator Cluster as an AVS on the Tangle Network.

🚀 Features

• Automated devops for running DVT clusters.
• Automatically performs Obol's DKG process
• Tangle Network integration for on-demand instancing of DVT clusters

🛠️ How It Works

1. Cluster Configuration: The blueprint defines the structure for configuring a Distributed Validator Cluster, including the number of operators, threshold for signing, and validator details.
2. Leader Selection: For simplicity, the leader is simply the first operator.
3. Distributed Key Generation: Automatically performs Obol's DKG ceremony process
   • Each operator creates an ENR, and then shares them with the leader.
   • The leader uses these ENRs to create the DKG config
   • The leader distributes the DKG config back to the other operators
   • The DKG ceremony starts, generating the cluster definition files.
4. Tangle Integration: Allows on-demand instancing of Obol DVT clusters using Tangle's operator set.

📋 Pre-requisites

• Docker
• Docker Compose
• cargo-tangle

💻 Usage

To use this blueprint:

1. Review the blueprint specifications in the src/ directory.
2. Follow the Obol documentation to understand the Distributed Validator setup process.
3. Adapt the blueprint to your specific cluster configuration needs.
   • For simplicity, this blueprint by default will simply copy the sample Holesky config. This can be changed here.
4. Deploy the blueprint on the Tangle Network using the Tangle CLI:

$ cargo tangle blueprint deploy

5. Activate the DV
   • See the Obol documentation for this section. Once the operators have finished the DKG ceremony, the deposit-data.json file will be generated, and can be taken from any of the operators.
