StarkWare Introduces Quantum-Safe Bitcoin Transactions Without Protocol Changes
A breakthrough proposal from Avihu Levy suggests that Bitcoin can achieve quantum-resistant transactions today—without any changes to its core protocol.
The newly introduced Quantum Safe Bitcoin (QSB) system operates entirely within Bitcoin’s existing rules, eliminating the need for a soft fork or network-wide upgrade. By shifting from traditional elliptic curve cryptography to hash-based security, the approach aims to protect transactions from future quantum computer threats while maintaining full compatibility with the current network.
However, the solution comes with trade-offs. QSB transactions require significant computational power, costing an estimated $75–$150 per transaction and often needing direct submission to miners due to non-standard transaction formats. While the system offers up to 118-bit quantum-resistant security, experts view it as a temporary or “last-resort” solution rather than a scalable long-term fix. As concerns over quantum computing grow, the development highlights both the urgency of future-proofing Bitcoin and the challenges of upgrading a decentralized network.
