The Daml ledger model defines:

  1. what the ledger looks like - the structure of Daml ledgers
  2. who can request which changes - the integrity model for Daml ledgers
  3. who sees which changes and data - the privacy model for Daml ledgers

The below sections review these concepts of the ledger model in turn. They also briefly describe the link between Daml and the model.
