Vitalik: We need to lead the construction of anti-fraud technology in a principled way

In response to Wu Blockchain question: Tokens or products based on permissionlessness and decentralization will inevitably be exploited by criminals, scammers or kidnappers, what should we do? Vitalik replied: The construction of anti-fraud technology needs to be led in a principled way (because if we don't, the centralized version will be imposed on us in an unprincipled way). In order to reduce cryptocurrency kidnapping incidents, wealthy cryptocurrency holders should be encouraged to keep their funds in multi-signature accounts that they cannot directly access through information or items on their bodies. 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).
