KERI & vLEI Concepts

Well-known witnesses are KERI witness nodes initialized with predetermined salts for key store generation, creating predictable witness identifiers exclusively for testing environments where reproducible witness configurations are required.

In KERI/ACDC/CESR context, a clone refers to a duplicated or replicated instance of a key event log, identifier state, or cryptographic data structure that maintains identical content and verification properties while potentially existing at different network locations or storage systems.

In KERI/ACDC context, a branch refers to a cryptographically linked path within a directed acyclic graph (DAG) structure of ACDCs, where each branch represents a verifiable chain of data provenance from a root ACDC through intermediate nodes to leaf nodes.

In KERI/ACDC systems, 'iss' is an abbreviation for 'verifiable credential issuance' - the cryptographically secured process of creating and delivering ACDC credentials from an issuer to a holder using IPEX protocol flows.

A hierarchical multi-signature threshold structure in KERI limited to exactly two levels: individual split-key configurations and team-of-teams arrangements, designed to optimize CESR encoding while supporting tightly cooperating entities through weighted signature schemes.
