The premise it starts from is worth the read on its own — SAP systems are trusted but mutable, which is what an immutable anchor is for — and Cardano is chosen for peer-reviewed research and formal methods rather than for popularity. Written as an experiment with feedback invited, not as a recommendation.","short":"ODATANO, Cardano blockchain proofs reachable from CAP over OData V4","author":"maxalexweber","published":"2026-05-15","sources":[{"url":"https://community.sap.com/t5/sap-cap-blog-posts/adding-immutable-blockchain-proofs-to-sap-with-cap-cardano-and-odata-v4/ba-p/14370241","title":"Adding Immutable Blockchain Proofs to SAP With CAP - Cardano and OData V4 — SAP Community","checked":"2026-09-07"}],"provenance":{"discovered_via":[{"source":"source:sap-community","channel":"cap-group"}],"first_seen":"2026-09-07"},"drafted_with_ai":true,"published_on":"source:sap-community","history":[{"date":"2026-10-17","field":"explains","from":null,"to":"applies_to on capability:odata (cap)","reason":"Door scope proposed from the title and summary, so a door page lists the piece only where it holds (docs/concepts/content-on-doors.md)."}]},"readings":{"liveness":[{"label":"Checked against the source","tier":"unknown","evidence":"nobody has checked it"},{"label":"Source reachable","tier":"unknown","evidence":"not crawled"},{"label":"Age","tier":"good","evidence":"published 5 months ago"}],"compatibility":[{"label":"Version","tier":"unknown","evidence":"no version declared"},{"label":"Moved since?","tier":"good","evidence":"no recorded change after 2026-05-15"},{"label":"Findings","tier":"good","evidence":"none flagged"}],"reach":[{"value":745,"unit":"views"},{"value":0,"unit":"comments"},{"value":3,"unit":"likes"}]},"signals":{"views":745,"likes":3,"comments":0,"metrics_at":"2026-10-25"},"series":null,"edges":{"authors":[]}}
