# Architecture first, not technology first
Fundamental requirements: individual control · portability · permissions · interoperability · local/private processing · provenance · verification · identity · open protocols. Blockchain may or may not be useful for particular components; it is not the innovation. A decentralized identifier (DID) is an optional later step, never the core.[^word-brief-20260922]
