A 1993 Fidonet document (re-discovered and posted to HN) describes a decentralized message network that presaged modern distributed systems. Fidonet (1984-2000s) connected BBS systems via nightly dial-up exchanges. Key technical innovations (in 1984!): (1) Store-and-forward messaging - TCP/IP without TCP/IP. Messages hop from node to node. (2) Federated addressing - Zone:Net:Node/Point was the original federated identity (3) Content moderation - FidoNet had a network coordinator who could remove nodes violating rules, the original community moderation system. Why Fidonet declined: (1) Cost - long-distance phone charges (2) Speed - 2400 baud (30 bytes/second) limited content (3) Centralization - AOL and later the web offered easier access. Lessons for 2026: Fidonet's decentralized architecture was not adopted because centralized alternatives (web, cloud) offered better user experience. Decentralization has a UX tax. ActivityPub (Mastodon, Bluesky) faces the same challenge: technically superior but UX falls short of centralized (Twitter, Instagram). The lesson: decentralization only wins if the UX gap is bridged.
