Bluesky is a decentralized social media platform that emerged from an initiative within Twitter Inc. to develop a decentralized social network protocol, now known as the AT Protocol, the standard on top of which the Bluesky platform has been built. It is a microblogging social platform and a public benefit corporation based in the United States. Bluesky is currently in beta, with registration only available to those with an invite, but the company has outlined its plans for eventual rollout to the general public. The service is focused on microblogging and has been called "Twitter-like".

Bluesky is built on an open-source protocol called the AT Protocol, which provides transparency into how the app was built and works. The platform emphasizes user autonomy, allowing users to dictate their feed and how content is moderated. Bluesky is customizable, and users can subscribe to multiple different custom feeds. The platform is split into two feeds, one of which operates just like classic Twitter, where users see the posts of the people they choose to follow, and the other is a federated design with community-specific moderation.

Bluesky is currently only available to desktop and iPhone users, with Android access in the works. The app is still in beta, and review bombing because users cant get in is childish. Bluesky has been described as a viable alternative to Twitter, but it is much smaller than Twitter, with over one million inquiring users on its waitlist and more than 40,000 users given access to Bluesky as of last week.

In conclusion, Bluesky is a decentralized social media platform that is currently in beta and focused on microblogging. It is built on an open-source protocol called the AT Protocol, which provides transparency into how the app was built and works. The platform emphasizes user autonomy, allowing users to dictate their feed and how content is moderated.
