AT Protocol
The open underlying protocol of the Bluesky platform, with the full name Authenticated Transfer Protocol. It is designed to enable identity authentication and data transfer across a decentralized social network, allowing interoperability among different service providers.
Core Facts
Bluesky's technical foundation is the AT Protocol (Authenticated Transfer Protocol), a decentralized social networking protocol independently developed by Bluesky.
The AT Protocol introduces the concept of a 'Personal Data Server' (PDS), allowing users to self-host their data.
Timeline (last 90 days)
Bluesky was initially launched with funding from Twitter (now X) and later operated independently, with its underlying technology being the AT Protocol.
The AT Protocol allows users to store their identity, follow list and published content on a server of their choosing, and to migrate between different applications.
The AT Protocol contains two core mechanisms: portable identity (implemented through DID decentralized identifiers) and federated data storage (Personal Data Server).
Multiple different social applications can be built on the same AT Protocol, sharing the underlying data and social graph.
In Bluesky's architecture, transaction history, review records and reputation scores can be bound to identity rather than to the platform, and when a user switches to another application based on the AT Protocol, these trust credentials can theoretically still be verified and inherited.
使用searchPosts接口时需遵守速率限制，避免对平台造成过大负载。
AT Protocol的API对外开放且无需付费密钥，开发者可以自由调用searchPosts、getAuthorFeed等接口获取公开数据。
This Bluesky weekly report was automatically generated based on the open AT Protocol API, scraping trending topics and AI brand mentions on the platform.
该AI品牌提及量数据的采集方式是通过AT Protocol的searchPosts接口，每个关键词最多扫描300条帖子。
searchPosts接口允许开发者按关键词、语言、时间范围等参数检索平台上的公开帖子，调用时通常需要携带访问令牌（JWT），但无需为每次请求付费。
