According to CoinMeta, Ethereum co-founder Vitalik Buterin stated at the 12th Blockchain Global Summit that with the enhancement of AI and data analysis capabilities, merely keeping real names unrelated to transactions is no longer sufficient to protect privacy on the blockchain. He pointed out that users' demands for blockchain are surpassing those of just payment, and they are placing higher expectations on performance and functionality. Modern cryptography also extends its protection from digital assets to information, making privacy protection programmable.
