As Elon Musk finalized his Twitter deal, Jack Dorsey launched a beta for his new social-media company

Just as Elon Musk was finalizing his purchase of Twitter, Jack Dorsey, the company's founder and former CEO, announced a beta for a new social-media company.

Dorsey's blockchain-based Bluesky Social announced last Tuesday that it's launching soon and is currently enlisting users for beta testing. The initial news drew 30,000 sign-ups within two days.

Bluesky website said it's intended to support a new foundation for social media which gives creators independence from platforms, developers the freedom to build & users a choice in their experience.

One of its Bluesky's main selling points is that its technology — which it calls "AT Protocol" — will give users control of their algorithms.

Dorsey had said in 2019 that Twitter was funding work into developing "an open and decentralized standard for social media."

Dorsey cofounded Twitter in 2006 and had several years-long stints as CEO, most recently from 2015 to November of 2021, when he stepped down.

Parag Agrawal, who was then chief technology officer of the company, replaced him. Shortly after taking over Twitter this week, Musk fired Agrawal.

Musk reportedly fired them "for cause" to avoid having to pay severance payments and unvested stock award
