Bluesky is a decentralized social network built upon the Authenticated Transfer (AT) Protocol, an open standard designed for the distribution of self-authenticating data. This protocol aims to move the social web away from centralized platforms toward a distributed model that empowers users with control over their digital lives. By early 2026, the platform reached a significant milestone of over 43 million users, hosting approximately 20 billion public records, including posts, likes, and replies. This vast ecosystem, frequently referred to as the Atmosphere, supports a growing variety of interoperable applications and third-party services.
A core principle of the network's architecture is the separation of user identity and data from the specific applications used to access the network. Users manage their identity through a dual system featuring mutable handles, which can be verified as custom domain names, and immutable decentralized identifiers known as DIDs. This framework ensures high levels of data portability, meaning individuals can migrate their accounts and social connections between different servers without the risk of losing their audience. The technical foundation relies on Personal Data Servers to host user repositories, while specialized relays aggregate updates into a real-time data stream called the firehose.
End-user experiences are delivered through platforms called AppViews, which process the firehose data to create customized interfaces. Moderation is notably decentralized, utilizing "opinionated services" and labelers that allow users to choose and stack different layers of content curation and safety filters. Furthermore, the network supports custom feed generators, enabling communities to build and subscribe to independent algorithms for discovery and topic-based discussion.
In March 2026, the company underwent a leadership transition as the founding CEO moved into a new role as Chief Innovation Officer to focus on protocol development. An interim CEO with extensive experience in open-source software was appointed to lead the company's scaling and commercial execution. During this period, it was also disclosed that the company had secured a $100 million Series B funding round, which had originally been finalized in April 2025. These funds are being utilized to expand the team, improve network throughput, and lower the barriers for developers building on the protocol.
The platform's roadmap emphasizes monetization through user-centric services rather than traditional advertising models. Planned subscription features focus on self-expression tools, such as custom profile icons, extended video uploads, and enhanced domain management. Additionally, the organization is prioritizing a system that allows creators and curators to receive direct payments for their work, with the platform taking only a small transaction fee. Technical utility has also expanded to include end-to-end encrypted messaging integrated directly into the interface through collaborations with external security startups. Ongoing work includes standardizing the protocol's core services with international engineering groups to ensure long-term stability and interoperability across the web.
