Ethereum co-founder Vitalik Buterin stated that he prefers multisig over the Shamir backup because he said Shamir is "more error-prone." As concerns grow about the security risks of cold wallets, Buterin advocated the use of multisig solutions to secure personal funds. However, while acknowledging the benefits of Shamir, Buterin noted that Shamir is "more error-prone" compared to multisig because it relies on careful storage and handling of many pieces of confidential information. 🔐
