Electra Upgrade: Update Validator Specification

[boulder225]

🎯 Problem to be solved

The current consensus specifications need to be updated to incorporate the changes introduced by the upcoming Electra upgrade. This document outlines the specifications for validators, such as:

EIP-7549

• Moves the committee index outside of the Attestation container to simplify aggregation logic;
• Clarifies network vs on-chain aggregation rules;
• Flattens the aggregate_bits field;

EIP-7594 (PeerDAS)

• Adds the PeerDAS protocol for distributed data availability sampling;
• Includes fixes related to cryptography and networking for PeerDAS;

Other Changes

• Initializes the Electra configuration with EIP-6110 (Blob transactions) and EIP-7002 (Sync protocol);
• Tracks blob gas usage when upgrading to Electra;
• Incorporates EIP-7251 (Inactivity leak) changes like increasing MAX_EFFECTIVE_BALANCE;

🛠️ Proposed solution

• Update the validator specification to include the changes from EIP-7549, which:

  • Moves the committee index outside of the Attestation container
  • Clarifies network vs on-chain aggregation rules
  • Flattens the aggregate_bits field

• Implement the PeerDAS protocol (EIP-7594) for distributed data availability sampling, including:

  • Fixes related to cryptography and networking for PeerDAS

• Initialize the Electra configuration with:

  • EIP-6110 (Blob transactions)
  • EIP-7002 (Sync protocol)

• Track blob gas usage when upgrading to Electra

• Incorporate changes from EIP-7251 (Inactivity leak), such as:

  • Increasing MAX_EFFECTIVE_BALANCE
