Attest wants your receipts to outlive the store

Field notes

Attest packages a seller’s signed license grant with the buyer-held receipt, allowing a verifier to check issuer keys and artifact hashes without contacting a surviving service. The homepage demonstrates the flow with a fictional Nebula Games receipt and supports a replayable salt-disclosure proof for buyer binding. The project is at specification v0.1; its stated v0.2 direction includes optional transparency, anchoring, and issuer-mediated transfer records.
