phase-4

Phase 4 — Decrypt-after-ordering (now reveal TxObject, still opaque)​

4.1 Threshold decryption​

Committee runs threshold decryption on ciphertexts in the agreed order:

  • TxObject_1, TxObject_2, ...

Reminder: even now TxObj is still “opaque”:

  • no addresses
  • no amounts
  • just commitments, nullifiers, encrypted outputs, proof artifact

4.2 Quick anti-DoS checks (optional)​

Sequencers/provers may do cheap checks:

  • tx format valid
  • size limits
  • nullifier duplicates within the same batch (fast reject)
    (Full correctness is enforced by the final batch proof + on-chain verification.)
