Misconception: KERI Requires a Blockchain

Misconception: "KERI is blockchain identity, so it must depend on a shared ledger."

KERI uses cryptographic event logs, receipts, witnesses, and watchers to make identifier state verifiable. A blockchain can be useful infrastructure around KERI, but the root of trust lives in the identifier and its Key Event Log (KEL), not in a validator network.

Summary

What the clips cover

• Samuel Smith - the ledger wars. Early SSI conversations often became arguments about which ledger should hold identity. KERI's insight is that portable identity should not be locked to one ledger.
• Samuel Smith - identity without blockchain. KERI was designed so decentralized identity can work without requiring blockchain consensus.
• Thomas Mayfield - blockchain hashchain comparison. KERI uses hash-chained data structures like blockchains do, but a KEL is per-identifier rather than one global shared ledger.
• Thomas Mayfield - off-chain identity. Blockchain integration can make sense for some use cases, but identity itself should remain off-chain.

Why it matters

Blockchains solve double spending for scarce digital assets. Most identity state changes need consistency and duplicity detection, not global ordering by a consensus network. That is why KERI can be decentralized, portable, and scalable without being tied to the blockchain trilemma.
