    Abstract: An blockchains are secure by design and are an example of a distributed computing system
and blockchain is suitable for the identity management transaction processing. In this study, we suggested a
user authentication service based on blockchain. Blockchain technology enables entities independent of each
other to rely on the same shared, secure and auditable source of information in a way that fits well with a system
of widespread digital identity. The proposed model can be applied to various systems while guaranteeing
secure authentication of users. Therefore, users can conveniently use various services without generating
many accounts and passwords.
