Prover API

A Prover is a participant that receives confirmed Cohort information from the Manager and provides it in a static form. The Prover can be an API or a decentralized static file system. Unlike the Manager API, the Prover API protocol must utilize precise implementations. External systems must appropriately call the API according to the Prover version to obtain Proof.
