# ToIP Trust Spanning-layer Protocol (TSP) Proposal: A Secure Identifier Overlay for the Internet

A 97-slide deck by Samuel M. Smith proposing, for ToIP (Trust over IP), that the trust spanning layer be an identifier system security overlay built on KERI (Key Event Receipt Infrastructure) autonomic identifiers. The file is named for 8 March 2023 but its title slide keeps the 2023/02/08 date of the earlier 61-slide version. For specification contributors and implementers.

Labels: reading level Implementer; evidence informative (an author's paper, deck, tutorial or post explaining the suite).
