📌 New: Signed content for a world where platforms are AI
AI-mediated communication systems measurably shift the opinions of the groups they serve. Polish, suggest, summarise, rewrite. Each tap nudges. The aggregate shifts. "Did this person say this thing" is becoming a real question, not because identities are forged, but because the path from "what the human meant" to "what arrived on the platform" now routinely runs through a model.
Durable content provenance requires three layers working together: C2PA for structured manifests (who, when, what tools, what edits, AI involvement), blockchain for platform-independent anchoring (manifests survive arbitrary hops because the cryptographic anchor is not attached to the file), and decentralised identity to bind the signer (a DID outlives any platform that issued it).
C2PA alone is necessary but fragile. Blockchain alone does not capture the structured provenance C2PA provides. Decentralised identity alone has no content to attest to. Pair the three and the question of authorship becomes tractable again.
This is Day 5 of the Ontology Roundup, Issue 01.
