ZAP1 Attestation Protocol (Ɔbaakofoɔ a ɔtɔ so mmienu)
ZAP1 is an open-source attestation protocol for Zcash. It writes structured lifecycle events to a BLAKE2b Merkle tree and anchors the tree root on-chain via Orchard shielded memos. Proofs are publicly verifiable. Event data stays private.
Sɛnea ɛyɛ adwuma no
Operators register event types (deployments, payments, transfers, etc.) and submit them to a ZAP1 instance. Each event produces a leaf hash using domain-separated BLAKE2b-256. Leaves accumulate in a Merkle tree. Sɛ wɔdu ɛdan bi mu na wonya akatua no wie a, wɔde dua no nhini di dwuma sɛ ZAP1:09 memo ma ɛyɛ adwuma wɔ Zcash so wɔ dwumadie bi a wɔn ani da hɔ so.

N'adeε a ɛho hia paa ne:
- ** Application-agnostic**: obiara a ɔde Zcash di dwuma no betumi akyerɛ ne dwumadie ahodoɔ ne n'ankasa ahwehwɛde ahorow ase.
- Ahobanbɔ-a ɛhwɛ so: dwumadi no ho mfasoɔ a wɔde di dwuma wɔ hash mu ansa na w'atwe ato hɔ. Hash nko ara na ɛkɔ on chain.
- Independently verifiable: verification hia proof bundle ne chain access nkoara. no operator trust required.
- ZIP 302 compatible: ZAP1 resane akɔfa ZIP 302, partType ama adansedie no so mfasoɔ.
