BitGo Prepares Institutions for Quantum Risk with New Controls

BitGo has introduced four new quantum controls for institutional Bitcoin wallets to measure and reduce public-key exposure before quantum attacks become practical. The controls aim to prepare institutions for a potential future risk, as there is currently no practical way to break Bitcoin using a quantum computer.

The Quantum Risk Score gives clients an in-platform measure of exposure across supported wallets. However, BitGo has not published the formula or thresholds used by this score.

The new controls also include a UTXO selection method that groups coins by address and attempts to include every other associated UTXO, as well as a Fix Exposed Addresses workflow to move affected funds into newly generated addresses. Updated default settings are intended to reduce reliance on address types and transaction patterns that create earlier exposure.

Taproot and Pay-to-Public-Key funds require separate remediation because they expose public-key information from creation. BitGo has not yet identified support for these remediation paths in the current product release.
