The web uses one-way links (page A links to page B, but page B does not know), no built-in versioning (when a page changes, the old version is usually lost), no automatic attribution for quotations, and no built-in payment system. The web won because it was simple — Berners-Lee designed it to be implementable in a few months. Xanadu was too complex to build with the technology available in the 1960s–80s. But Nelson's ideas remain relevant because the problems they solve (link rot, lost history, unattributed copying, lack of creator compensation) are major issues on the modern web.","status":"active","vx_hash":"ce36999d6cd1a37fdc1f514fc85b11316ac09e64bb12c08c7a9e73c84aafc7fd","semantic_hash":null,"version_hash":null,"version":1,"sources":[],"falsifiers":[],"tier":null,"backed":null,"transcludes":null,"chain_head":"6ab6dafc94f568e554867e26409bf9399ae51883b39f37a726d21e45336c5ff5","chain_length":1,"chain":[{"n":1,"op":"genesis","ts":"2026-07-17T02:43:01.556Z","actor":"owner","text_sha":"6f198f21da302fc33ab7005a13afc4cbf586d8b7a14b91728c9ba225756bbd7a","detail":{"divided_from":"body","block":9,"kind":"p"},"prev":"genesis","hash":"6ab6dafc94f568e554867e26409bf9399ae51883b39f37a726d21e45336c5ff5"}],"claim_ids":[],"last_op":{"op":"genesis","actor":"owner","ts":"2026-07-17T02:43:01.556Z"},"consolidated_into":null,"stable_url":"https://miscsubjects.com/i/div/thinker-ted-nelson/d9"},{"id":"d10","kind":"h","type":null,"order":10,"text":"### The Key Idea","status":"active","vx_hash":"193389ce6a1257b5e0c088f82d801e28fab79abc90a2d10f4ba87bc388013acd","semantic_hash":null,"version_hash":null,"version":1,"sources":[],"falsifiers":[],"tier":null,"backed":null,"transcludes":null,"chain_head":"322a3145ae86098e78f629ccf6c6dfecee41ad280e740a0239a263fe5142f67a","chain_length":1,"chain":[{"n":1,"op":"genesis","ts":"2026-07-17T02:43:01.556Z","actor":"owner","text_sha":"441af1806499f3c61d7189137057d9d38e063ccdca01d669193809ee90c0ef2d","detail":{"divided_from":"body","block":10,"kind":"h"},"prev":"genesis","hash":"322a3145ae86098e78f629ccf6c6dfecee41ad280e740a0239a263fe5142f67a"}],"claim_ids":[],"last_op":{"op":"genesis","actor":"owner","ts":"2026-07-17T02:43:01.556Z"},"consolidated_into":null,"stable_url":"https://miscsubjects.com/i/div/thinker-ted-nelson/d10"},{"id":"d11","kind":"p","type":null,"order":11,"text":"Nelson's central concept is that documents should be connected by reference, not by separation.

OIP's append-only ledger (a database where new entries can be added but old entries cannot be deleted or modified) implements Nelson's versioning principle — nothing is ever lost. OIP's receipt graph (a network of interconnected verification records) creates transclusion-like reference chains where each receipt references the data it verifies.\n- **Content-addressed storage (IPFS, 2015).** The InterPlanetary File System stores data by its cryptographic hash — a mathematical fingerprint of the content.
