Combining Blockchain and Artificial Intelligence – Literature Review and State of the Art

Artificial intelligence and blockchain are among the most popular technologies. Combine the two technologies also harbors manifold potentials. For instance, blockchain can help address specific AI-related difficulties such as the black box problem. Vice versa, AI offers opportunities to improve the blockchain’s mining process, or smart contracts. Despite their relevance for companies, these combination solutions have so far received little attention. We undertake a systematic literature review to close this research gap and to provide a first comprehensive overview of this emerging field. We do so by providing a threefold categorization of the different options for connecting the blockchain and AI.
