Cryptocurrency custodian BitGo (BTGO) is introducing quantum-resistant security features to its institutional Bitcoin wallets, The Block reported. Addresses with public keys exposed on-chain even once are expected to be vulnerable to quantum computer attacks. BitGo's new feature is designed to group UTXOs (unspent BTC) by address and sort them by risk level, allowing institutions to adjust their quantum-related risk. BTC addresses where the public key is exposed from the start, such as Taproot or Pay-to-Public-Key, are not supported. BitGo has filed a provisional patent for this feature. Meanwhile, Coinbase's independent advisory committee on quantum computing and blockchain estimated last month that approximately 7 million BTC could be exposed to quantum computer attacks.
