Overview

Rust based implementation of the IETF Draft Public Transaction Event Logs (PTEL) specification. TEL is a state machine, where any state change of this statee machine is represented as append only, end-verifiable log that derives its foundations from Event Sourcing and adds cryptographic authenticity on top of that.

TEL proposed here is a issuance revocation state machine, which constists of three states:

• NULL -- given member does not exist yet in the registry;
• issued -- given member declares it is present/issued;
• revoked -- given member declares it is removed/revoked.
