The Web Needs a Context Layer Built on a Shared Protocol
Making context a shared protocol, rather than a platform feature, would let readers see competing perspectives anywhere on the web, argue Mallory Knodel, Evan Friedman, and Brad Friedman.
ATOM: AT Protocol Over MoQ Transport
This document specifies how the Authenticated Transfer (AT) Protocol can leverage Media over QUIC Transport (MOQT) for efficient data synchronization across decentralized social networks. The AT Protocol's firehose event stream and repository synchronization mechanisms map naturally to MOQT's publish/subscribe model, enabling scalable relay infrastructure, priority-based delivery, and improved resilience for large-scale social data distribution. This specification addresses the challenges of the current WebSocket- based transport and demonstrates how MOQT's relay architecture, group-based caching, and multiplexed streams provide significant benefits for AT Protocol deployments at scale.
