[Galaxy: The Threat of Quantum Computing to Bitcoin is Real, but Not an Imminent Crisis; Developers Are Already Taking Action] Deep Tide TechFlow news, March 19, according to a report by CoinDesk, Galaxy Digital's Head of Research Alex Thorn stated that the threat of quantum computing to Bitcoin is real, but it does not currently constitute an imminent crisis. Investors should not misinterpret this long-term technological challenge as an immediate reason to avoid Bitcoin. Thorn pointed out that the current risk is limited to specific addresses with exposed public keys on-chain, including reused addresses, addresses held by certain custodial institutions, and assets in older address formats. Analysis by security firm Project Eleven shows that approximately 7 million BTC (equivalent to about $470 billion at recent prices) are in such "long-term exposure" states but remain secure under existing quantum computing capabilities. In terms of countermeasures, developers have advanced several solutions, including introducing new address types based on post-quantum cryptography, implementing a "hourglass" mechanism to restrict spending permissions for permanently exposed public key addresses, and fundamentally reducing the broadcasting of public keys during transactions through phased upgrade paths.
