Bluesky was initially incubated inside Twitter as former CEO Jack Dorsey’s vision for what the future of social media should look like. But the social network and developer of the open source AT Protocol is no longer affiliated with Dorsey, who left the startup’s board earlier this year. Still, many of the initial goals for Bluesky remain consistent: like Mastodon, Bluesky’s AT Protocol is decentralized, meaning that individual people will be able to set up their own social servers and apps, and people outside of the company have transparency into how and what is being developed.
