When TikTok bites the dust (like this expected to do so on Sunday), billionaire Mark Cuban says he is open to funding an alternative video sharing platform built from the protocol developed by microblogging site Bluesky.

Since the exit of President Joe Biden signed an order Demanding that TikTok sell its platform in the US or risk a country ban, there is much anticipation as to what will fill the void if the app does indeed take off in the country. Many people want to buy the original app from ByteDance, its parent company in China. ByteDance has repeatedly said it will not sell. Now, Cuban is proposing an alternative version of the video-sharing app that could be better for everyone in the long run.

Cuban shared the idea of a TikTok video Posted on his account on Tuesday. “There’s an app called Bluesky and it’s built on the AT Protocol,” Cuban said. “I’m open to investing in supporting anyone—or anyone who makes a replacement for TikTok built on the AT Protocol. So if you have that ability, let me know in the comments,” Cuban said. “If you make one an MVP—a minimum viable product—so I can see it, much better, because obviously, I think you have a lot of support,” Cuban said.

Whether Cuban will actually follow through on such an investment is unknown, although the idea is intriguing. The appeal of Bluesky is that it is supposedly a “decentralized” social media platform, as it allows users to host their data on servers other than those owned by the company. While the majority of decentralized web users don’t count out Bluesky as an official part of the Fediverseand some claim that the site is just that “cosplay” decentralizationthe site has some benefits that you don’t get on a site like X or Facebook. Its AT Protocol is a federated protocol that allows users to create their own interoperable apps and servers, while maintaining relationships with Bluesky’s user base. In that sense, it allows users more autonomy than other sites.

Bluesky tries to present itself as the antidote to X—the once popular microblogging site that nutjob tech billionaire Elon Musk has since acquired CONVERTED to his own private propaganda apparatus. The platform was created by Twitter founder Jack Dorsey in 2019 as a Twitter side-projectthen returned to its own company when Musk took over Twitter. From then on, it was Dorsey separate ways with the platform, but the site has continues to grow. A recent study claims that the so-called “Twitter-quitters” have helped increase Bluesky’s user base of more than 27 million people (for comparison, X has approx 250 million daily users).

While the idea of ​​having a TikTok-esque site that functions more or less like Bluesky is cool, it’s not clear that TikTok’s US app will actually die. The company is doing everything it can to court incoming President Donald Trump in hopes of getting a last-minute reprieve. On Thursday, this reported that TikTok’s CEO, Shou Chew, will attend Trump’s inauguration. Trump also said that he is considering an executive order to save the platform.
