Bluesky is microblogging social network and an initiative to develop a protocol for decentralized social networking. Its flagship service, bsky.app was launched as a beta in early 2023.

Despite being based on a decentralized protocol, Bluesky remains centralized in practice as no third-party services that can interact with bsky.app have gained traction. Will this change before the end of 2024?

This question resolves to YES if there is a service that meets the following criteria:

• The service is not controlled by Bluesky.

• The service can interact with bsky.app in terms of things such as following and replies between users on both services. (This need not be through the AT Protocol, in case bsky.app integrates with the Fediverse, for example.)

• The service allows users to create accounts separate from bsky.app. (That is, it is not simply an alternative "view" to an account on bsky.app. In the AT Protocol federation architecture this would likely mean a separate PDS.)

• The service has at least 100 users. (If multiple such services exist, they must have a combined total of at least 100 users.)

• Credible evidence of meeting these criteria emerges before 00:00 UTC on January 1, 2025.

If no such service exists, then question resolves to NO.

I may provide liquidity subsidies but will not otherwise trade in this question.
