Bitcoin Researchers Propose Quantum-Resistant Transaction Method

A new proposal aims to protect Bitcoin transactions from potential quantum computing threats by utilizing a different type of cryptographic proof.

The Quantum Safe Bitcoin (QSB) system, developed by Avihu Levy of StarkWare, replaces standard digital signatures with hash-based verification. This approach is designed to be more resistant to attacks from advanced quantum computers.

However, the QSB system comes with significant costs, requiring $75-$200 worth of GPU computing resources per transaction. It also cannot propagate through Bitcoin's standard network infrastructure and lacks compatibility with the Lightning Network.
