币界网报道：Vitalik Buterin, co-founder of Ethereum, has raised concerns about the privacy risks associated with single digital identity systems, cautioning that such centralized solutions could lead to excessive surveillance and control. Speaking at a recent event, Buterin highlighted the potential dangers of governments or corporations monopolizing digital identity frameworks, which could undermine individual privacy and autonomy. He emphasized the need for decentralized alternatives that empower users to control their own data without relying on a single authority. Buterin pointed to blockchain-based solutions, such as self-sovereign identity (SSI) systems, as a more secure and privacy-preserving approach. These systems allow individuals to manage and verify their identities across multiple platforms without exposing sensitive information to third parties. The Ethereum co-founder also warned against the misuse of digital identity systems for censorship or exclusion, particularly in financial services and social platforms. His comments come as governments worldwide explore national digital ID programs, with some facing criticism over data security and human rights concerns. Buterin's advocacy for decentralized identity aligns with broader Web3 principles of user ownership and interoperability, offering a counterpoint to traditional centralized models. The discussion reflects growing debates over balancing innovation, privacy, and regulation in the digital identity space.
