However, the logs are easily altered by an attacker. In addition, the integrity of logs may not be maintained due to program malfunction or user's erroneous operation. Using a robust infrastructure can reduce the damage of tampering.But it costs money. In this paper, we propose a log storage system using Blockchain. The proposed system provides highly integrity log storage using a Blockchain that is difficult to alter or delete.
