Services

zkRP is a set of services that share the encrypted P2P substrate and a gRPC control plane. Full request/response detail is in the gRPC API reference.

auth service (zrp.auth.v1)

Anonymous enrollment and credential issuance. AuthService proves an email is eligible and issues a blind credential without ever learning who enrolled; the only state persisted is a set of 32-byte nullifiers. Deployed on its own port (PORT).

controller (zrp.relay.v1, zrp.mailbox.v1)

A libp2p relay node plus a gRPC control plane, served on GRPC_PORT:

• RelayService - relay discovery (ListRelays), Health, Stats, a streaming WatchStats, and relay Register/Deregister.
• BlobStore - chunked, streaming blob upload and download backed by object storage.
• Logging - client-streaming debug-log upload.
• MailboxService - store-and-forward Deposit/Fetch so an offline device can be reached without the relay knowing who it is.

libghost / ghost protocol

The encrypted P2P library and its wire envelope (zrp.v0.ghost.GhostEnvelope: version, time nonce, payload). This is the transport the services ride on, not a gRPC service.
