📜 Create Reference Attestation Contracts for A-Chain

[zeekay]

Develop standard smart contracts for the new Attestation Chain (A-Chain) functionality.

Overview

Create reference implementations for attestation submission, verification, and aggregation on A-Chain.

Timeline (3 weeks)

Week 1 (Jan 27-31, 2025)

• Core Attestation Contracts (4 days)
  • IAttestation interface
  • AttestationRegistry contract
  • OracleRegistry contract
  • ThresholdSigVerifier contract

Week 2 (Feb 3-7, 2025)

• Specialized Attestations (4 days)
  • TEEAttestation for secure enclaves
  • GPUAttestation for computation proofs
  • MLModelAttestation for AI verification
  • DataOracle for external data

Week 3 (Feb 10-14, 2025)

• Testing & Documentation (3 days)
  • Comprehensive test suite
  • Gas optimization
  • Integration examples
  • Developer documentation

Contract Architecture

interface IAttestation {
    function submit(bytes calldata proof) external returns (bytes32);
    function verify(bytes32 attestationId) external view returns (bool);
    function aggregate(bytes32[] calldata ids) external returns (bytes32);
}

Key Features

• CGGMP21 threshold signature support
• BLS signature aggregation
• Ringtail lattice signatures
• Gas-efficient verification

Deliverables

• Core contracts in contracts/attestation/
• Test suite with 100% coverage
• Gas optimization report
• Integration guide
