Aya Miyaguchi, chairperson of the Ethereum Foundation, said at the WebX2025 event held in Japan on August 26 that there are risks to the traditional national identity model that relies on government systems, such as the vulnerability of centrally stored citizen information to be erased or tampered with in the face of external attacks. Take Bhutan as an example. The country is creating a decentralized national ID system and migrating to Ethereum.
