Composing capability security and CRDTs
K.3.201 | Day 2 | 14:05 - 14:20 | Speakers: David Thompson
Abstract
CRDTs allow for decentralized replication of data. Capability security allows for decentralized control over behavior. Local-first applications often use access-control list (ACL) security which has significant downsides versus capabilities, especially in a decentralized context. In this talk, I'll examine how CRDTs and capabilities can be composed to improve the security of local-first applications using a group chat prototype as a case study.
Speakers
David is the CTO at the Spritely Institute, a US-based nonprofit working on decentralized networking technology for safe collaboration. At Spritely, he works on Goblins, a capability-secure distributed programming environment, and Hoot, a Scheme to WebAssembly compiler and general-purpose WebAssembly toolchain. He is a longtime contributor to the Guile and Guix projects and the author of software such as Haunt, a purely functional static site generator.
