zk-admission

What is zk-admission and what is it for?

zk-admission is a Holochain admission protocol that lets an agent submit proofs tied to a credential secret and an operator-issued admission capability. It is designed to let a deployment validate admission claims while checking that the proof is bound to that deployment and the submitted statement.

zk-admission, also called zk-admission in its README, is a protocol for checking admission credentials in a Holochain deployment. Its repository contains Rust crates for the protocol, proof generation and verification, and an integrity zome that validates submitted entries.

In practical terms, an agent can submit a record showing knowledge of a credential secret for an admission capability issued by the deployment operator. The design checks two proofs: one covering the full statement and another covering the secret-to-nullifier relation; the README cautions that these proofs do not establish whether the credential issuer is valid.

For example, the README describes a credential holder proving knowledge of a secret associated with a deployment-scoped nullifier, without making the secret itself the public proof.
