Quantum Safe Bitcoin Scheme Achieves 118-Bit Security Against Shor’s Algorithm Threat

QSB is a scheme for Bitcoin transactions designed to remain secure against the threat of Shor’s algorithm, without requiring any changes to the existing Bitcoin protocol. It achieves this by modifying Binohash, replacing a vulnerable component with a hash-to-sig puzzle relying on the pre-image resistance of RIPEMD-160.

Quantum Safe Bitcoin Emerges: A $200 Fix for Bitcoin’s Quantum Threat

TLDR: Quantum Safe Bitcoin works within Bitcoin’s existing consensus rules, requiring no soft fork or miner signaling. Each QSB transaction costs between $75 and $200 due to heavy off-chain GPU computation requirements. QSB replaces ECDSA signature security with hash-based proofs that quantum computers cannot easily break. Levy frames QSB as a last-resort emergency tool, not a substitute for long-term fixes like BIP-360. A StarkWare researcher …

There’s a Way to Make Bitcoin Safe From Quantum Without a Fork, Researchers Say

A new proposal suggests Bitcoin users could defend against future quantum attacks using a transaction design that works within the network’s existing rules.
