Strategy, the world’s largest corporate Bitcoin holder, says the network can adopt enhanced security measures if they become necessary against quantum computing threats. Bitcoin relies on elliptic curve cryptography and a sufficiently powerful quantum computer could one day theoretically recover private keys from exposed public keys. No publicly available quantum computer is currently capable of breaking Bitcoin’s cryptography in this way. Michael Saylor estimates that a quantum-resistant upgrade could be deployed in about 90 days after global consensus, while the Bitcoin Security Consortium, backed by $15 million, is researching post-quantum cryptography and the BIP-360 proposal.
