Block-chain technology is rapidly evolving into ICT technology. In order to write data to a block in a blockchain system, a new block must be created in the lockchain system. However, in order for a new block to be created, it takes time for proof of work.(PoW). During the block generation process, It is impossible to provide a services using the data. IoT devices transmit huge amounts of data in real-time. Therefore, a method that can guarantee real time is needed. In this paper, we propose a real-time guarantee method of distributed database using blockchain to solve the above problem.
