Why verifiable AI needs blockchain
Model cards and API terms of service are promises. We think verifiability should be a property you can check, not a promise you have to trust.
Every model provider publishes a model card describing what a system is and isn't
supposed to do. But a model card is a promise, not a guarantee — there's no way for a
third party to check, after the fact, that a given output actually came from the model
described.
Blockchain gives us a narrow but useful tool here: a public, tamper-evident record that a
specific proof was verified at a specific time. Combined with zero-knowledge proofs of
inference, this lets us turn "trust us" into "check for yourself" — without requiring anyone
to hand over proprietary model weights.

This is the thinking behind Ledgermind, and we think it generalizes well beyond our own
work. We'd like to see verifiable inference become a standard expectation for any model
making consequential decisions.
