Core actors and objects

Actors​

  • User wallet (client): executes privately + proves (with prover layer)
  • Relayer (optional but recommended): hides IP/timing
  • Sequencer committee: orders txs, commits ordering, threshold-decrypts
  • Prover layer: build chunk proofs + aggregate proof
  • DA layer: stores batch blobs (encrypted logs, commitments, nullifiers, etc.)
  • Solana program: verifies final proof + updates roots (canonical truth)
  • Indexers (optional): help wallets fetch/scan faster (untrusted)

Core objects (what exists)​

Private tx object (opaque; contains no addresses/amounts)​

TxObj includes:

  • proof_tx (proof of correct private execution for this tx OR a proof-ready witness commitment)
  • nullifiers[]
  • new_commitments[]
  • encrypted_outputs[] (ciphertexts for recipients)
  • optional: public_hooks (bridge/fee hooks; minimize)
  • tx_commitment (hash)

Batch header (what committee signs)​

BatchHeader:

  • old_state_root
  • new_state_root
  • new_nullifier_root
  • batch_hash (commitment to DA blob)
  • batch_index
