AI Has a Trust Problem. Can Blockchain Help?

The difficulty of ensuring artificial intelligence algorithms are safe, unbiased and accurate is turning some companies to a technology once hyped as transformative, but that has failed to catch on in business: blockchain.

Known for underpinning bitcoin and other cryptocurrencies, blockchain is a data structure that makes it possible to create a digital ledger of transactions and share it among a network of computers. It uses cryptography to allow each participant in the network to add to the ledger in a secure way without the need for a central authority. Once a transaction is made, the blockchain remains an immutable record of it.
