Second, blockchain technology can achieve the immutability of identity information. Once identity information is stored on the blockchain, it cannot be tampered with or misused. Additionally, blockchain technology also has the controllability of identity information. Users can autonomously control their own identity information and decide whether to disclose it anonymously. To achieve these functions, there are already some blockchain projects attempting in the field of digital identity verification, such as  Civic and uPort. These projects have implemented decentralized authentication through blockchain technology."}]}],"pr":"44c05c5912e70de6ea3f8768778ebcf10b35559ec80c132ccd9ead2aa08aaa88"}
