Explore a decentralized authorization framework called WAVE in this lecture by Raluca Popa from UC Berkeley. Delve into the concept of transparency logs and their application in blockchain technology. Learn about Certificate Transparency's guarantees, data structures used by log providers, and auditing processes. Understand the challenges of decentralized authorization and how WAVE addresses them through graph-based authorization. Compare traditional approaches with WAVE's innovative system. Examine the storage layer requirements and how Certificate Transparency principles are applied. Investigate the log provider's and server's data structures, and discuss the importance of revocation in this framework.
