BitGo to launch quantum-safe tools for institutional Bitcoin wallets
New features add wallet key exposure management, UTXO optimization and a patent-pending UTXO grouping method to help institutions reduce future quantum-computing risk.
BitGo said it will launch quantum-resistant tools for institutional Bitcoin wallets in the coming weeks, adding wallet key exposure management, UTXO optimization and a patent-pending UTXO grouping method to its multisignature custody architecture. The company has framed the release as a way for institutions to assess, manage and reduce quantum-computing-related risks in UTXO wallets before protocol-level post-quantum signature upgrades are required. The updated details sharpen BitGo’s earlier outline of the product set, which includes an in-platform Quantum Risk Score for supported Bitcoin wallets, a Fix Exposed Addresses Workflow to move funds from addresses with elevated exposure into new addresses, and controls intended to reduce the risks created by partial spends and address reuse. BitGo said the new feature is designed to group and prioritize UTXOs to reduce risks tied to partially spent outputs, and that the tools apply across supported UTXO-based assets and multisignature configurations. BitGo has also said no quantum computer can break Bitcoin today, while arguing institutions should begin reducing risk in advance. It cited estimates that 6.9 million Bitcoin are held in addresses with exposed public keys.
- UTXO optimization: Techniques for managing unspent transaction outputs to reduce wallet exposure and improve how coins are selected for spending.
- Quantum Risk Score: BitGo's in-platform rating system for assessing potential quantum-computing exposure across supported Bitcoin wallets.
- multisignature custody: A custody setup that requires multiple keys or approvals to authorize transactions, reducing single points of failure.
