From eb63194c56fce5dad7a941e39f25d57569c03c06 Mon Sep 17 00:00:00 2001 From: Christomatt Date: Tue, 27 Jan 2026 01:27:15 +0100 Subject: [PATCH] refactor: Migrate from ActivityPub federation to native Swarm network - Remove ActivityPub infrastructure (webfinger, nodeinfo, inbox, activities, signatures) - Implement native peer-to-peer Swarm network with gossip protocol - Replace federated timeline with Swarm timeline aggregating posts from all nodes - Migrate direct messaging to end-to-end encrypted Swarm Chat system - Update user interactions (follow, like, repost) to use Swarm protocol - Add cryptographic key management for DID-based identity system - Remove server-bound identity model in favor of portable DID identities - Update documentation to reflect Swarm architecture and capabilities - Add debug utilities and chat testing tools for Swarm network - Refactor database schema to support distributed user directory - Update bot framework to work with Swarm network interactions - Simplify API routes to use Swarm protocol instead of ActivityPub - This transition enables true peer-to-peer communication, instant interactions, and encrypted messaging while maintaining sovereign identity through DIDs --- README.md | 76 +- SWARM_CHAT.md | 10 +- debug_chat.ts | 27 + src/app/.well-known/nodeinfo/route.ts | 16 - src/app/.well-known/webfinger/route.ts | 56 -- src/app/api/account/moved/route.ts | 33 +- src/app/api/posts/[id]/like/route.ts | 21 +- src/app/api/posts/[id]/repost/route.ts | 28 +- src/app/api/posts/[id]/route.ts | 9 +- src/app/api/posts/route.ts | 127 ++-- src/app/api/search/route.ts | 73 +- src/app/api/swarm/chat/messages/route.ts | 12 +- src/app/api/swarm/chat/send/route.ts | 64 +- src/app/api/swarm/inbox/route.ts | 4 +- .../api/swarm/interactions/follow/route.ts | 4 +- src/app/api/swarm/timeline/route.ts | 8 +- src/app/api/users/[handle]/follow/route.ts | 197 ++---- src/app/api/users/[handle]/following/route.ts | 2 +- src/app/api/users/[handle]/inbox/route.ts | 89 --- src/app/api/users/[handle]/posts/route.ts | 302 +------- src/app/api/users/[handle]/route.ts | 163 +---- src/app/chat/chat.css | 571 +++++++++++++++ src/app/chat/page.tsx | 475 +++---------- src/app/globals.css | 26 +- src/app/inbox/route.ts | 94 --- src/app/nodeinfo/2.1/route.ts | 36 - src/app/page.tsx | 16 +- src/components/LayoutWrapper.tsx | 7 +- src/db/schema.ts | 16 +- src/lib/activitypub/activities.ts | 240 ------- src/lib/activitypub/actor.ts | 192 ----- src/lib/activitypub/cache.ts | 210 ------ src/lib/activitypub/fetch.ts | 82 --- src/lib/activitypub/fetchRemotePost.ts | 169 ----- src/lib/activitypub/inbox.ts | 668 ------------------ src/lib/activitypub/index.ts | 7 - src/lib/activitypub/outbox.ts | 125 ---- src/lib/activitypub/signatures.ts | 165 ----- src/lib/activitypub/webfinger.ts | 116 --- src/lib/auth/index.ts | 4 +- src/lib/background/remote-sync.ts | 27 +- src/lib/bots/botManager.ts | 6 +- src/lib/bots/mentionHandler.ts | 2 +- src/lib/bots/posting.ts | 62 +- src/lib/crypto/keys.ts | 36 + src/lib/swarm/index.ts | 2 +- src/lib/swarm/interactions.ts | 3 +- src/lib/swarm/timeline.ts | 8 +- try_create_chat.ts | 46 ++ 49 files changed, 1173 insertions(+), 3559 deletions(-) create mode 100644 debug_chat.ts delete mode 100644 src/app/.well-known/nodeinfo/route.ts delete mode 100644 src/app/.well-known/webfinger/route.ts delete mode 100644 src/app/api/users/[handle]/inbox/route.ts create mode 100644 src/app/chat/chat.css delete mode 100644 src/app/inbox/route.ts delete mode 100644 src/app/nodeinfo/2.1/route.ts delete mode 100644 src/lib/activitypub/activities.ts delete mode 100644 src/lib/activitypub/actor.ts delete mode 100644 src/lib/activitypub/cache.ts delete mode 100644 src/lib/activitypub/fetch.ts delete mode 100644 src/lib/activitypub/fetchRemotePost.ts delete mode 100644 src/lib/activitypub/inbox.ts delete mode 100644 src/lib/activitypub/index.ts delete mode 100644 src/lib/activitypub/outbox.ts delete mode 100644 src/lib/activitypub/signatures.ts delete mode 100644 src/lib/activitypub/webfinger.ts create mode 100644 src/lib/crypto/keys.ts create mode 100644 try_create_chat.ts diff --git a/README.md b/README.md index ede9035..b5a6480 100644 --- a/README.md +++ b/README.md @@ -1,26 +1,28 @@ # Synapsis -Synapsis is an open-source, federated social network built to serve as global communication infrastructure.
