Bluesky is often called a decentralized Twitter alternative and viewed as a competitor to the tech giant. But Bluesky was also the brainchild—and largely the creation—of Twitter. In December 2019, Twitter announced that they were funding an independent team to work on an open and decentralized social media standard. The founder of Twitter, Jack Dorsey, actually expressed the desire for Twitter to eventually be a client (user) of the standard that Bluesky was working on.
In August 2021, it was announced that Jay Graber, formerly a Zcash developer, would be helming the Bluesky team and its initiatives going forward. In February 2022, Bluesky became a completely independent organization following the formation of its Public Benefit LLC. In October 2022, the Bluesky app was announced to notable fanfare—with its waitlist receiving approximately 30,000 sign ups in two days. In February 2023, the Bluesky app was released in beta version on the Apple App Store (at time of writing, no Android app version is available).
Available initially for download by invite only, Bluesky opened its doors to the public in February 2024, after amassing some 3 million users since it launched in beta. Within 24 hours of its public launch, Graber claimed that 550,000 new users had signed up to the platform.
The Bluesky user experience
While still in beta (a test phase for software, video games, and apps prior to a full release), Bluesky as an app appears to be largely modeled on Twitter itself. While essentially a rival to Twitter and other Twitter alternatives, the initial reaction from some is that it feels too similar, having features like comments, likes, and reposts (like Twitter’s retweets). This includes how these posts, replies, and the feed itself are visually presented to Bluesky users. While there are some differences, they are largely minor (a post character limit of 265 instead of 280, for example).
While the user experience (UX) for Bluesky app users has been surprisingly familiar for those who have previously used Twitter, others point out that you need to look below the surface-level UX to understand why Bluesky could be a social media gamechanger. While Bluesky is currently a proof of concept that has so far succeeded—not failed—in having certain functionalities of a centralized social media platform like Twitter, the underlying technology—and the possibilities it enables—is what all the commotion is about.
Bluesky’s innovative networking technology: AT Protocol
While the UX and the features of Bluesky resemble Twitter to a significant degree, the key goal of Bluesky isn’t aesthetics, features, or the UX—the chief goal wasn’t even to create a decentralized Twitter competitor; superseding all of these objectives was the desire to create a decentralized social network protocol that could be used by anyone. Called authenticated transport (AT) protocol, this is the technology upon which Bluesky is built.
While Bluesky is the first major release on AT protocol, the technology is open and available for use by any user, developer, or company (in much the same way anyone can build on a public blockchain like Ethereum). This means that others could create their own social media platforms using AT protocol technology. Even Twitter could potentially be run on AT protocol as Jack Dorsey had hoped, although with Twitter’s change of ownership this may be a less likely scenario.
AT protocol enables new ways for users to transparently communicate with each other.
Thanks to these features, many see the AT protocol (not the Bluesky app) as the key innovation. While Bluesky gets all the headlines, the AT protocol could fundamentally change the social media landscape in ways that aren’t merely technical or abstract (more on that later). The AT protocol is an amalgamation of decentralized technologies (but not a blockchain writ large). In essence, the AT protocol would enable the creation of not a single social network, but a federation of social networks that could interact with each other.
AT protocol enables new ways for users to transparently communicate with each other. At a technical level, this would allow you to self-host the servers of your own company, profile, or social media platform. This is in stark contrast to existing social media platforms where the self-hosting of servers and data simply isn’t possible. The goal of such a design is to secure user data and make the user platform experience resistant to influence from corporations, governments, and other centralized entities. AT protocol has the ability to put users in control of their data and how it is used (or not used). While being able to host your own servers is an option, users that don’t want to run their own servers can simply delegate a host of their choosing and use Bluesky like any other social media app.
What Bluesky and AT Protocol mean for social media users
In the current landscape, major social media platforms (Twitter, Facebook, TikTok, Instagram, Youtube) are largely siloed ecosystems that don’t interact with each other. If you are on multiple social media platforms, you likely have different followers, friends, and content—and view different content. And if you don’t like a social media network you are using, you don’t have a lot of good options. While you can always use an app less, stop using it, or find an alternative, it can often be a hard choice to make.
If you decide to leave, you often find yourself in a smaller ecosystem than the one you left. Further, you often have to start over by creating a new account, adding new friends and follows, and so on. Beyond that, you may find that many of the people you want to engage with don’t use these social media alternatives. Regardless of your reason for disliking a platform or certain aspects of it (over/under moderation, the algorithm, data privacy, censorship, and so on), users often continue to use these platforms due to a lack of viable alternatives and the headache associated with starting from scratch on a new social network. With AT protocol, one key feature is the ability to port over a social media profile to another network—without losing the key data and social contacts you value.
For example, let’s say you have a Bluesky account with a username handle, hundreds of contacts, messaging history, and so on. If for some reason you didn’t like how Bluesky was operating, you could simply port over your entire account to a Bluesky alternative that is built on the AT protocol and continue as if nothing changed. This solves one of the major pain points of leaving and joining social networks.
Not to say that you would necessarily want to leave Bluesky, however, as it allows for a great degree of customization and user control not available on other social media platforms. One goal of Bluesky is to revitalize transparent and public conversation on social media by tamping down on the disinformation and authoritarian manipulation sometimes found in the digital social media landscape.
