# CESR: Composable Event Streaming Representation for CESR/KERI/ACDC/SPAC-TSP Protocol Stack and other Cryptographically Agile and Cryptographically Heavy Protocols

A 28-slide deck by Samuel M. Smith, dated 2024-04-17 and filed as given at the Internet Identity Workshop (IIW) in spring 2024, explaining Composable Event Streaming Representation (CESR) 2.0. It covers the case for a composable dual text and binary encoding, the code tables and parsing rules, annotated streams, size comparisons with JSON, CBOR and MessagePack, and uses in archives, legal signatures and audit trails, for implementers.

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