<\/div>\n

BitGo Holdings, Inc. (NYSE: BTGO) introduced a set of tools to help institutions measure and reduce the quantum-computing risk tied to their Bitcoin holdings. The digital asset infrastructure company said<\/a> the features apply to UTXO-based wallets and its multi-signature custody service.<\/p>\n\n\n\n

The release builds on BitGo’s multi-signature architecture<\/a>, which the firm pioneered for Bitcoin to reduce single points of failure. The new controls give clients more visibility into wallet-key exposure, better handling of unspent transaction outputs, and workflows for institutional wallet operations.<\/p>\n\n\n\n

At the center of the launch is a Quantum Risk Score, an in-platform system that rates potential quantum exposure across supported Bitcoin wallets. A Fix Exposed Addresses Workflow guides clients through moving funds from addresses with elevated exposure into new addresses with stronger key hygiene. <\/p>\n\n\n\n

A new UTXO Selection Method groups and prioritizes coins by address to limit the exposure that partial spends create. Updated default address-type controls steer wallets away from transaction patterns that raise quantum<\/a> concerns.<\/p>\n\n\n\n

Bitcoin could face quantum attacks<\/h2>\n\n\n\n

The risk stems from how Bitcoin addresses work. An address whose public key has appeared on-chain could, in a future with capable quantum machines, face attack. <\/p>\n\n\n\n

Estimates place<\/a> 6.9 million Bitcoin in addresses with exposed public keys. Funds in address types that reveal a public key from creation, such as Taproot or Pay-to-Public-Key, fall outside the scope of the application and need separate remediation.<\/p>\n\n\n\n

“We believe the safest key is one whose public key has never been revealed on-chain,” said Mike Belshe, CEO and co-founder of BitGo. “These capabilities give institutions a practical way to understand and reduce quantum exposure while continuing to rely on the proven security of multi-signature.”<\/p>\n\n\n\n

BitGo said no quantum computer can break Bitcoin at present. Adam Back<\/a>, co-founder and CEO of Blockstream and BSTR, framed the timing as a reason to act. “Nobody has a quantum computer that can touch Bitcoin today, but that’s exactly why the work should start now, while it’s calm and optional rather than urgent and forced,” he said.<\/p>\n\n\n\n

The company described the tools as a complement to future protocol-level post-quantum signature upgrades to Bitcoin, rather than a replacement. <\/p>\n\n\n\n

The features cover supported UTXO-based assets and multi-signature configurations.<\/p>\n","protected":false},"excerpt":{"rendered":"
