It was conceptualized and initially funded by former Twitter CEO Jack Dorsey. A key technical achievement is the development of the Authenticated Transfer (AT) Protocol, which underpins the network and is designed to support features like account portability and algorithmic choice. The Bluesky PBLLC, a public benefit company, oversees the protocol's development. The project is currently in a developmental phase, having launched a beta version of its social application to a growing user base.
