# State

The did module keeps state of Identities, represented as the evolution of the DID Document and Metadata for a certain DID.

# Store

The module appends in the store the updated Identity.

Key Value
did:identities:[address]:[updated] → Identity

This operation uses the block time (guaranteed to be deterministic and always increasing) to populate the Updated field of Metadata. This timestamp is also used to populate the Created field, but only for the first version of the Identity, that will be maintained in the newer versions.
