Quantum-Safe Bitcoin Transactions Without Protocol Changes: A Feasible Solution?
Why it matters right now
The development of quantum-safe Bitcoin transactions that require no changes to the existing protocol offers a practical approach to enhancing security without the need for consensus-driven upgrades.
Key talking points
- Starkware's CPO, Avihu Levy, introduced Quantum Safe Bitcoin (QSB), enabling quantum-resistant transactions using existing Bitcoin rules.
- QSB operates within Bitcoin's legacy Script constraints, requiring no protocol changes or community coordination.
- The scheme achieves approximately 118-bit pre-image resistance against quantum attacks at a cost of $75 to $150 per transaction.
- Potential implications for Bitcoin's security and the broader adoption of quantum-resistant measures.
- Challenges and considerations in implementing QSB, including transaction costs and scalability.

Intro paragraph
In response to the looming quantum threat, Starkware's CPO, Avihu Levy, has proposed Quantum Safe Bitcoin (QSB), a scheme that enables quantum-resistant transactions without necessitating changes to Bitcoin's existing protocol. This innovative approach offers a practical pathway to enhancing Bitcoin's security in the face of advancing quantum technologies.
