Blockchain can be used to track exactly what data an algorithm was trained on, when, by whom, as well as what other steps were taken to vet and verify that data, said Scott Zoldi, FICO’s chief analytics officer. Companies building AI models typically try to follow that data trail, but using blockchain would make it easier to end up with shared, consistent, trustworthy records, he said.
Blockchain won’t stop algorithms from going off the rails or exhibiting bias—but it would offer an auditable record that could show why, he said.
