"textContent": "* * *\n\nThe Federation Across Networks series is complete. Three posts, in the order they should be read:\n\nThe Bridge to Bluesky: What Happens When Two Protocols Try to Talk - AT Protocol and ActivityPub aren't the same idea implemented differently. They were built independently to solve different problems. In this post, we take a look at Bridgy Fed - a bridge that attempts to connect ATproto & ActivityPub networks.\n\nThreads Enters the Fediverse (With Caveats) - Meta promised fediverse federation. Then delivered it. But adoption is low - as of early 2025, only 25,900 out of 200 million Threads accounts had opted in. Only ~800 had actually followed a Mastodon account. In this post, we cover Threads entry into the fediverse.\n\nNostr and the Protocol Bridges - Nostr departs from ActivityPub and AT Protocol at the identity layer: your account is a cryptographic key pair, not a server account. Every action (post, follow, reaction, profile update) is a signed JSON event broadcast over WebSocket to relays. In this post, we cover Nostr's architecture, the relay layer, and the full bridge ecosystem.\n\n* * *\n\n* * *\n\nThe Federation Across Networks series covered the edges of the fediverse where it meets protocols built on different assumptions.\n\nThe next series, _The Fediverse Beyond Mastodon_ , stays entirely within ActivityPub and maps what's already there.\n\nMastodon has roughly a million, monthly active users. Pixelfed, PeerTube, Lemmy, the Misskey family, Pleroma, Ghost, WriteFreely, Bookwyrm, NodeBB — they're all on the same network, federating with each other and with Mastodon, built for different people with different assumptions about what social networking is for.\n\n* * *\n\n__Four post mini series,___****The Fediverse Beyond Mastodon****_ __, starts next week.__\n\nSubscribe to get notified when the next series drops",
