New Quantum-Safe Bitcoin Transactions Introduced, Costing Up to $200
- A StarkWare researcher has developed a method for quantum-safe Bitcoin transactions without altering the existing protocol.
- The new scheme, called Quantum Safe Bitcoin (QSB), costs between $75 and $200 per transaction due to heavy computational requirements.
- QSB replaces traditional ECDSA signatures with hash-based proofs, which are resistant to potential quantum attacks.
- Unlike standard transactions, QSB transactions must be sent directly to miners, bypassing the normal blockchain process.
- This solution is considered a temporary measure and not a replacement for more scalable long-term upgrades like BIP-360.
The introduction of QSB allows users to conduct Bitcoin transactions that are resistant to quantum computing threats without needing protocol changes. However, the high cost and complexity of these transactions present significant challenges for widespread adoption.
With transaction costs reaching up to $200, QSB offers a way to maintain security against future quantum threats while adhering to current rules.(Source)
