The following are outside the scope of this document: - requirements for implementing distributed ledger technology including blockchains; - requirements for technology to ensure immutability of data sets; - requirements for the processes of creating identifiers; - requirements for the processes of creating the content of off‑ledger data sets; - requirements for the processes of creating immutable data sets.
