Decentralizing AI Using Blockchain Technology for Secure Decision Making

Abstract

Lately, Blockchain and artificial intelligence (AI) have become two of the most popular and revolutionary technologies. Blockchain, the key technology behind Bitcoin, is a distributed database that allows transactions to be recorded in an incorruptible and non-modifiable manner. With smart contracts, Blockchain can be used to provide a decentralized/distributed environment where multiple parties can interact with each other without any trusted third party. On the other hand, AI enables machines to have intelligence and decision-making capabilities just like humans. This paper presents a thorough survey on how Blockchain technology can be used for empowering AI. We review the literature and summarize how Blockchain can make AI secure and efficient.
