Prove the fact. Keep the data private. Settle the outcome.
The expensive trust problems are KYB, trade finance, payments, marketplaces, supply chains, energy assets and commerce conducted by software. In each, the same ritual repeats: send the data room, wait, send it again to the next institution, hope nobody keeps a copy they should not have.
Replace the ritual with a credential. The fact is checked once. It can be shown again. It can be revoked when it stops being true. The underlying documents stay where they belong. Settlement can still be global, because the proof travels and the data does not.
