Artificial Intelligence (AI) and blockchain are among the most promising and widely deployed technologies in recent times. On the one hand, blockchain can enable interactions among clients without the presence of any trusted third party and provide access to a blockchain ledger that holds transactions, logs, and data in a decentralized, trusted, and secure manner. On the other hand, AI facilitates making intelligent decisions by observing the environment. This chapter presents an overview of integrating blockchain with AI technology, covering the importance, applications, challenges, and potential open research issues.
