What if instead of just connecting you to your digital wallet, your private key can connect you to your digital identity? This is the development direction of blockchain technology that many people see today. It provides a secure and unforgeable method for authentication. Blockchain identification can be used for anything. It simplifies online account registration. It can be used as a passport or driver's license. It can act as a card, user name, password, or any other role you need to establish identity. One of the main benefits of this new trend is that it will significantly improve the security of your identity. Blockchain recognition makes it possible to share only basic information. Think about any time you have to show your driver's license as proof of identity. They just need to know that you are you, but you have given them your address, birthday, etc.
