Golden Finance reported that Vitalik Buterin said on the X platform: As a field, we need to lead the construction of anti-fraud technology in a principled way (because if we don't, the centralized version will be imposed on us in an unprincipled way). The basic meaning of "principled" is: (i) In-device scanning, no information is sent to "Big Brother" (corporate or government) (ii) Users can choose very finely which scanners to accept and not accept, and scanners are produced in a competitive market by organizations with different structures (for-profit, community organizations, etc.) and different countries or political biases. Cryptocurrency kidnapping should be reduced by encouraging wealthy cryptocurrency holders to store funds in multi-signatures, and they themselves cannot directly access information/items on individuals. This is what I do, and I have been advocating others to do this for ten years (hence my focus on smart contract wallets and account abstraction).
