- 2026-10-27Chainlink re-checked: 418 price updates, all confirmedExperiment CL-01 independently re-checks every update of the Chainlink ETH/USD and BTC/USD feeds from 20 to 27 October 2026, from public data only (Ethereum ledger, Coinbase candles): f+1 signatures by configured operators, signed report equal to the event, median, heartbeat, closeness to the market. Result: 418 of 418 confirmed, largest distance to the market 0.015 %. Tamper tests show the check can also say no. Not an audit of Chainlink.
- 2026-10-23GEVP-11 published: built on SCITT and COSE ReceiptsWith RFC 9943 (SCITT) and RFC 9942 (COSE Receipts) now published, revision 11 builds on them: each verifier is an Issuer, each record a Signed Statement about the artifact under evaluation. Planned encoding: COSE_Sign1 with CWT Claims (RFC 9597) and Ed25519 (RFC 9864), using only existing IANA registrations. The encoding is described, not yet implemented.
- 2026-10-22GEVP-10 published: safety propertiesRevision 10 adds safety properties with a fault parameter t, a forgery bound and a contradiction veto, the relation to the RATS architecture, time bounds from independent time-stamp authorities and a data model in CDDL.
- 2026-10-13GEVP-09 published: a complete specificationRevision 09 specifies the protocol as precisely as the reference implementation v0.6.0: the format and signature of evidence records, the signed result (true, false, no verdict), a registry accepted under a threshold of root keys, a reproducible decision record and signed receipts that let an auditor check decisions without trusting the service. Our goal: publication as an RFC.
- 2026-10-12GEVP-08 published: a correctionRevision 08 replaces the unreproducible calibration figures of earlier revisions with reproducible results; the 0.73 threshold is no longer recommended. The earlier figures remain on record.
