M·O·R·S·E

The node states the hash is keccak256 over the payload and reports it verified. Morse shows that attestation as the node returns it: eleven serialisations of the payload as served were tried and none reproduced the hash, so Morse does not claim to have re-derived it independently (GAPS G3). What Morse does establish on its own is the payer — the wallet above is checked against Morse's.
