Commit Boost Beta Launch

Commit Boost is now available in beta, providing a secure proposer commitment signature service that enables validators to participate in advanced commitment protocols.

How Commit Boost Works

Commit Boost provides cryptographic signatures for proposer commitments that are:

• Chain-specific: Signatures are unique to each EVM chain (identified by chain ID)
• Module-specific: Each module has its own signing ID, preventing cross-module signature reuse
• Secure: Cannot be used to create Beacon chain attestations or cause slashing
• Standard-compliant: Supports both BLS (96-byte) and ECDSA (65-byte RSV) signatures

Technical Implementation

Signature Rules

• Data payloads must be 32-byte arrays (typically hash values)
• Signatures incorporate a unique module signing ID
• Uses Commit Boost domain type: 0x6D6D6F43
• Signatures are SSZ Merkle tree roots combining request data, signing ID, and domain

Module Integration

Your module requires a unique 32-byte signing ID that:

• Identifies your module during the signing process
• Must be configured in the Commit Boost configuration file
• Remains separate from the module's human-readable name
• Can be updated to invalidate previous signatures if needed

Signature Format

• BLS: Standard 96-byte BLS signatures
• ECDSA: Standard Ethereum r,s,v format (65 bytes)

Both signature types sign the 32-byte root hash of an SSZ Merkle tree containing the request data, signing ID, and domain.
