Introducing Tap: Repository Synchronization Made Simple | Bluesky

Just about every app built on AT needs data from a repository at some point. For many use cases – feed generators, labelers, bots – streaming live data through a Relay or Jetstream works well. But some applications need to go beyond what Jetstream was designed for, like tracking specific subsets of a repo, automatically backfilling a database when adding new repos to monitor, or even mirroring the entire Atmosphere.

Introduction

Every stream on Streamplace is cryptographically bound with metadata that captures details about how the stream should be viewed, used, distributed, and monetized. This metadata also identifies the provenance of the stream, including who the creator is and any transformations it has undergone. Any Streamplace node operator can inspect the stream and verify that this metadata is intact and trustworthy.

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.

Episode #140: Eli Mallon - Streamplace and the future of decentralized video streaming

This week we're joined by Eli Mallon, founder of Streamplace, a decentralized video streaming platform. In this episode we discuss the future of decentralized video streaming, the challenges of building a new platform, and how developers can leverage Streamplace's tools. We also go into Atproto, the decentralized social media network that stream place is built on. - https://stream.place/about - https://techcrunch.com/2025/04/04/beyond-bluesky-these-are-the-apps-building-social-experiences-on-the-at-protocol - https://github.com/iameli - https://www.linkedin.com/in/eli-mallon-5703a94a - https://bsky.app/profile/iame.li - https://www.livepeer.org/ Episode sponsored By WorkOS (https://workos.com) and Mailtrap (https://l.rw.rw/devtools_2) Become a paid subscriber our patreon, spotify, or apple podcasts for the full episode. - https://www.patreon.com/devtoolsfm - https://podcasters.spotify.com/pod/show/devtoolsfm/subscribe - https://podcasts.apple.com/us/podcast/devtools-fm/id1566647758 - https://www.youtube.com/@devtoolsfm/membership
