The cryptocurrency custodial service BitGo is preparing to implement advanced solutions aimed at protecting Bitcoin wallets from threats associated with the development of quantum computing. In the coming weeks, the company will introduce a whole set of tools to institutional clients designed to minimize risks arising as the era of quantum supremacy approaches.
Among the key innovations is an address vulnerability assessment system that will allow real-time identification of which wallets are most susceptible to potential attacks using quantum algorithms. Special attention is paid to addresses with reuse (P2PK and older formats), which are considered the most vulnerable.
The second important component is the automatic transfer of funds from wallets deemed risky. This is a proactive measure: if the system detects that a private key could be compromised by a quantum computer in the foreseeable future, funds are instantly moved to protected addresses using algorithms resistant to quantum hacking.
The third tool is a new method for selecting unspent transaction outputs (UTXO). BitGo is implementing an algorithm that optimizes UTXO selection in a way that minimizes the likelihood of revealing information about the wallet structure and reduces the attack surface for quantum systems.
These measures are particularly relevant amid growing concerns that quantum computers could disrupt Bitcoin's cryptographic security by cracking ECDSA, the algorithm underlying the signatures of most transactions. Although a full-fledged threat is still years away, BitGo is betting on a proactive approach, which is reasonable for the institutional level.
My expert assessment: Implementing quantum protection at the custodian level is not just a trend, but a necessity. BitGo demonstrates a strategic vision that will likely become the standard for the entire industry in the next 3-5 years. Institutions working with large volumes should already reconsider their security policies now, otherwise they risk being caught off guard when quantum computers become commercially available.
