Strategy, the world’s largest corporate holder of Bitcoin, has moved to reassure the market that Bitcoin can defend itself against future quantum computing threats. In a post on X, the company stated: “Quantum-resistant upgrades can be adopted if & when it's needed.”
The remarks arrive as the crypto industry weighs whether advanced quantum computers could eventually crack Bitcoin’s elliptic curve cryptography. A sufficiently powerful quantum machine could reverse-engineer private keys from exposed public keys, potentially exposing holders’ funds. At present, however, no publicly known quantum computer can break Bitcoin’s cryptography.
Michael Saylor, Strategy’s co-founder, previously told the World Bank in October that the Bitcoin network could coordinate a software upgrade within about 90 days once consensus emerges on quantum-resistant cryptography. He also cautioned that rushing new cryptographic measures could introduce new vulnerabilities, and some observers note a network-wide migration would require developers to agree and users to move funds to secure addresses.
Strategy is already involved in long-term Bitcoin security research. In July, it joined BlackRock, Coinbase and other firms in the Bitcoin Security Consortium, which committed $15 million over three years to areas including post-quantum cryptography. Meanwhile, developers are examining proposals such as BIP-360, which introduces Pay-to-Merkle-Root transaction outputs.
