Just saw the quantum protection solution launched by BitGo. The idea of UTXO grouping + reducing public key exposure is quite interesting — the quantum threat hasn't arrived yet, but laying out operational defense strategies in advance is much smarter than waiting for the technology to mature and then firefighting.

Crypto custodian BitGo has announced a new quantum-proof security tool designed to help institutions assess, manage, and mitigate the quantum computing-related exposure risks of their UTXO-based Bitcoin wallets. The tool extends BitGo’s multi-signature security architecture, grouping and prioritizing UTXOs through a new patented technology to reduce key exposure risks from partial spends. BitGo CEO Mike Belshe stated that institutions do not need to wait for quantum threats to become reality before managing related risks, and the core strategy lies in addressing future post-quantum challenges through operational hardening and reducing on-chain public key exposure.
