When AI and algorithms act and decide, who can check?
On today's platforms, AI and algorithms act and decide millions of times a day: listings removed, accounts suspended, content taken down. Europe's Digital Services Act gives everyone the right to complain and to an out-of-court settlement. But a dispute today is a pile of screenshots and e-mails.
Every side holds its own truth
The platform, the seller, the laboratory, the manufacturer — each keeps its own records. Nobody can show what the other knew, and when.
Evidence crosses borders, trust does not
A certificate from Slovenia, documents from China, a decision made in Germany, a complaint from Croatia — there is no common channel and no way to hand over evidence without handing over data.
Nothing can be verified afterwards
A regulator, a court or a journalist has to believe someone. There is no record that anyone can check for themselves.
Evidence and Audit Layer — without a shared database
A neutral layer under every party's records: evidence is sealed as it happens, audited by fingerprint, decided by people. Every party keeps its records at home; only a tiny fingerprint leaves.
A neutral record of who knew what, when — that no participant controls and that anyone can check.
Trust in a Zero Trust environment
For the regulatorA complete, checkable record of every step
Who knew what and when, which rule was applied, who decided, and whether the platform acted on it — reproducible by the regulator itself, not reported by the platform. A working model for Article 21 dispute settlement, ready for 27 regulators.
For platformsFair, fast and without handing over data
Decisions are judged on the evidence available at the time — a platform that acted correctly is shown to have acted correctly. Recommendations are non-binding; business records stay in the platform's own systems.
For businesses and citizensA complaint that cannot be lost
A resolution in days, not months, with a receipt that can be shown to a bank, a court or a customer. The same procedure whether the counterparty is next door or on another continent.
For EuropeOne procedure, cross-border evidence, no surrender of data
Evidence from anywhere in the world enters the procedure as a verifiable fingerprint; the dispute stays under European law. Cooperation without exporting either the data or the jurisdiction.
Four countries. One disputed decision.
A Chinese battery, a Croatian seller, a German marketplace on SAP/HANA, a Slovenian laboratory. The marketplace's AI removes the listing over a mistyped certificate number. Ten minutes later the dispute is resolved — and every person in the room has verified it.
No shared database
Four countries supply evidence; nobody hands over their records. The Chamber works with fingerprints.
The changed digit
One digit of the certificate is altered on stage. The document looks the same. The verifier turns red at once.
The QR code
The audience scans a code and their own phones recompute the whole resolution — no server asked, no one trusted.
The case facts are simulated. The infrastructure, the sealing, the Chamber workflow and the verification are live.
