Blockchain and artificial intelligence technology are selected as the promising future technologies of the fourth industrial revolution by Gartner 2018. Blockchain does not save all the transactions in the database and saves those in each node. Blockchain is a high-level cybersecurity technology which forms chains connecting the existing blocks and the new block chronologically after creating a new block by mutual agreement between nodes. Applications of blockchain can be diversified as including functions like the smart contracts. Artificial intelligence can be used for decision making or prediction. Convergence of the technologies accelerates development of various industries such as real estate, finance, insurance, IT, cybersecurity, prediction, medical service, biotechnology, crypto currency. Companies pioneer new markets using high-tech IT solutions such as blockchain, artificial intelligence, and IoT. In this paper, we explain application examples and plans for convergence technology of blockchain and aritificial intelligence. We suggest a virtual distribution center using the technology.
