Peergos: Capability-Based Access Control for an Encrypted Web
UD2.218A
English
<p>We introduce Peergos, a peer-to-peer protocol for end-to-end encrypted storage, social networking, and application hosting built on top of libp2p. Peergos combines cryptographic identity, content addressing, and decentralized access control into a unified protocol where users fully control their data, identity, and applications without relying on trusted servers.</p> <p>Instead of treating encryption as an add-on, Peergos integrates cryptographic capabilities directly into its data model: files, directories, social data, and application state are all encrypted and access-controlled by default. We will explain the design of Peergos’ capability-based access control, how key rotation and sharing work in practice, and how identity portability is achieved without central authorities.</p> <p>We will also introduce the Peergos application sandbox, which allows untrusted applications to operate over private user data without exposing plaintext or keys. This enables privacy-preserving apps such as social feeds, collaborative editing, and backups to run directly on encrypted storage.</p> <p>The talk will include live demos and a discussion of performance trade-offs, limitations, and open problems in decentralized encrypted systems, including search, discovery, and offline access.</p> <p>More info: https://peergos.org</p> <p>https://book.peergos.org</p> <p>https://github.com/peergos/peergos</p>
