Paper Title
Digital user Avatar on the Blockchain

The rapid growth in the number of users in the field of web2.0 and web3.0 increases the need for the research of systems that provide access to transparent and secure person’s identity. The lack of a unified system of this type forces services and governmental bodies to double-check the same information several times. This drives down user loyalty, requires additional labor costs of qualified specialists, and deteriorates security. A possible solution to this problem can be envisaged as the creation of the user's avatar in the blockchain. This research offers a solution with open-source code that decreases the time of deploying digital avatar management software. Its estimated reach is 1,595 billion users. Keywords - Blockchain, Authentication, Digital Avatar, Web3.0.
