The Trust Layer Between AI and the Chain

Walk into any technology showcase in 2026 and you will see something remarkable. A model reads a contract in seconds, flags the unusual indemnity clause, drafts a response and recommends a position. The room nods. The demonstration works. Then someone asks the only question that matters in the real world, the one the demonstration is designed never to provoke. Six months from now, when this recommendation is challenged, how do we prove the model actually saw that clause, that

The first pillar of proof is the seal. Sealing binds the record so that any change to it, however small, becomes detectable by anyone. The mechanism is a cryptographic signature computed over the full content of the record, the output and all its context, using a private key only the signing system holds. Anyone with the matching public key can verify that the record is exactly as it was when signed, and that the holder of that key signed it. Change a single character and the

The most expensive belief in enterprise artificial intelligence is that accountability is a layer you add later. Ship the capability now, the reasoning goes, and wrap it in audit and compliance once the value is proven. This is the retrofit fallacy, and it fails for a reason that is structural, not a matter of effort or budget. Most of what makes a record provable exists only at the instant of the action. The model version, the exact input, the configuration, the authority co
