According to CoinMeta, Justin Drake calls on the blockchain industry to enter a “fortress mode,” suggesting a gradual migration of assets to new addresses and the hiding of public keys in order to address the risk of private key cracking posed by AI. Vitalik recommends storing funds in addresses that have not yet been used for any transactions, but does not advise users to rush into migrating their assets immediately. It also suggests that multi-signature wallets use off-chain signatures for confirmation.
