OPENDATA ADAPTER
Twenty-one open sources.
Every fetch signed at contact.
The OpenData Adapter is one pattern applied twenty-one times: a source-shaped adapter fetches on cadence, signs the result at the moment of contact with that source's own Ed25519 key, and chains every row into a batch attestation. Nothing enters the record unsigned.
How we pulse it
Each source is polled on its own cadence, from minutes to daily, matched to how fast that instrument actually moves. Every fetch lands in our big-data ops, where the raw pull is kept append-only and then distilled into day-rows: one signed reading per subject per day. From there the readings travel as signed streams through one metered door, and surface in TruthFoundry as the instrument layer beside the news: prediction markets, legislation, macro releases, and seismic readings that independently see the subjects the news names.
A signature proves who fetched the data and that it was not altered afterward. Each source signs on its own key path (signals-3p/nasdaq, signals-3p/fred, and so on), every key is published in the signer registry, and anyone can verify a receipt at drm3.io/verify.

Beside these twenty-one sit the rest of the intake: the News Scanner reading 6,711 feeds in 51 languages, DomainDrift deep-probing 406,863 domains of internet infrastructure a day (7-day average), and the two decentralized-AI chain scanners, MorScan and dTAOscan. Every plane signs what it emits, and each is an independent witness of the world.
