KERI: For Every DID, a Microledger

– Medium

An introduction to Key Event Receipt Infrastructure (KERI), a new tool for decentralized identity

KERI has been developed by the Decentralized Identity Foundation in the hopes it will be adopted by the current prominent digital identifiers (DIDs). KERI acts as a ledger for interactions between keys and cryptographic systems, allowing for DID systems to trust each other.

“Each key event produces a receipt containing only checkable signatures of key event information. Nothing more.”

KERI can vastly enhance security by flagging when the signatures of two systems do not align. The system works much like a blockchain, though the technology is highly streamlined.

By offering a minimum level of security guarantees shared across all participating methods, it would simplify the security review process for both individual DID methods and for interoperable DIDs as a whole
