Phase 7 — Settlement on Solana (canonical finality)​

7.1 SubmitBatch instruction​

Submit to Solana program:

  • old_state_root
  • new_state_root
  • new_nullifier_root
  • batch_hash
  • proof_batch
  • committee signatures on BatchHeader

7.2 Solana program verifies​

On-chain:

  1. old_root matches current
  2. committee approval (M-of-N) is valid
  3. verify proof_batch
  4. update stored roots + batch index + last batch_hash

If this succeeds:

  • the batch is final and canonical
  • there is no revert model (validity rollup)
