Tracking Issue of Milestone 2: L1 Anchoring #34

This is a tracking issue for the L1 Anchoring.

Milestone 2: L1 Anchoring and Deep Integration with the Scroll Network

• Free L2 Attestations: Provides a free service for attesting data directly on the Scroll L2 network.
• L1 Attestations: Allows users to pay a micro-fee on L2 to have their data attested on both L2 and, subsequently, L1.
  • The L1 attestation is fully verifiable on L2.
  • Users can claim an NFT for each successful L1 attestation.
• Sustainable Model: The micro-fee covers operational costs to ensure the long-term sustainability of the service.
