Put differently
KELs are hash-chained Key Events. These are blockchains in a narrow definition, but not in the sense of ordering (not ordered) or global consensus mechanisms (which is not needed). (SamMSmith)
A KEL is KERI's VDS: the proof of key state of its identifier.
Other glossaries (or mental models)
key event log:
An ordered sequence of records of key events.
Note: Key event logs are a fundamental data structure in KERI.
