 Each event in a KEL MUST include an integer sequence number that is one greater than the previous event. Each event after the Inception event also MUST include a cryptographic digest of the previous event. This digest means that a given event is bound cryptographically to the previous event in the sequence. The list of digests or pre-rotated keys in the Inception event cryptographically binds the Inception event to a subsequent Rotation event, essentially making a forward commitment that forward chains together the events. The only valid Rotation event that MAY follow the Inception event MUST include the pre-rotated keys. But only the Controller who created those keys and created the digests can verifiably expose them. Each Rotation event, in turn, makes a forward commitment (chain) to the following Rotation event via its list of pre-rotated key digests.   This makes the KEL a doubly (backward and forward) hash (digest) chained nonrepudiably signed append-only Verifiable data structure.
 
-Because the signatures on each event are nonrepudiable, the existence of an alternate but Verifiable KEL for an identifier is provable evidence of Duplicity. In KERI, there MUST be at most one valid KEL for any identifier or none at all. Any Validator of a KEL can enforce this one valid KEL rule that protects the Validator before relying on the KEL as proof of the current key state for the identifier. Any unreconcilable evidence of Duplicity means the Validator does not trust (rely on) any KEL to provide the key state for the identifier. Rules for handling reconcilable Duplicity will be discussed below in section {{[  ]}}. From a Validator's perspective, either there is one-and-only-one valid KEL or none at all, which also protects the Validator by removing any potential ambiguity about the Key state.  The combination of a Verifiable KEL made from nonrepudiably signed backward and forward hash chained events together with the only-one-valid KEL rule strongly binds the identifier to its current Key state as given by that one valid KEL (or not at all). This, in turn, binds the identifier to the Controllers of the current keypairs given by the KEL, thus completing the tetrad.

 At Inception, the KEL can be bound even more strongly to its tetrad by deriving the identifier from a digest of the Inception event so that even one change in any of the incepting information included in the Inception event will result in a different identifier (including not only the original controlling keys pairs but also the pre-rotated keypairs).
