# ACDCs for Delegable Authorization: Solving broken delegation chain problems; EVAC, Agentic AI, and yet more bulk issuance

A 59-slide deck by Samuel M. Smith on using Authentic Chained Data Containers (ACDC) for delegable authorization, including control of AI agents. It presents Edge Verifiable Access Control (EVAC) with issuance and usage registries, reversion of delegation, blinded registries and bulk issuance, and the TSP (SPAC) protocol's ESSR message and tunnels.

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