Proof Submission Interface Methods

Below are the details about the API interface exposed by the Mainchain node to Proof Submitters.

SettlementFflonkPallet​

  • Type: non-blocking
  • Description: submit the proof and return the transaction hash if it is valid, error otherwise.
Signature: submitProof(proof, public_inputs) -> Result<tx_hash, Error>

In case of success, the proof is included in the mempool, relayed, and eventually included in a proposed block and then finalized.

RPC Commands​

  • Endpoint: PoE (Proof of Existence)
  • Description: get the Merkle path of the proof within the provided attestation, returning Error if the attestation_id’s Attestation event isn’t published yet.
Signature: proofPath(attestation_id, proof_leaf) -> Result<merkle_path, Error> Type: non-blocking

Currently these APIs are “embedded” into the PolygonCDK core code and not available the end user.
