[Vitalik: The Ideal Security Rule for Multisig is to Change Signer Keys After Each Operation] Odaily Planet Daily News – Vitalik posted on the X platform, stating that for multisig, the ideal security rule is for each signer to change their key after every operation. The implicit assumption of this rule is that while ECDSA may become insecure, it will not be instantly compromised, so precautions against mempool frontrunning are still necessary. Vitalik emphasized that, if possible, signatures should be collected offline to minimize the time gap between 'signature disclosure' and 'key invalidation.' Misconfigurations and rushed upgrades can easily lead to fund losses, so operations should not be conducted hastily.
