Public blockchains may be the only serious data management systems that take people and process out of the conventional security triad. They support a very specialized use case (peer-to-peer e-cash) without trust, which is almost the opposite of identity. Here we look at how new synchronous ledger technologies are being designed afresh for identity.

Learning Objectives:
1: Review what the original blockchain was designed for and what it cannot do.
2: Compare and contrast essential elements of blockchains and identity management.
3: Explore an R&D roadmap for rigorous design of synchronous ledgers for IdAM.
