Bitcoin quantum defense cost falls to $59; can it protect 6.04 million BTC with exposed public keys
The estimated computing cost to prepare for quantum-computer attacks on Bitcoin has fallen to $59, driven by GPU software optimisation, raising interest in protecting some coins without changing network rules. The figure is simulation-based and excludes network fees, with further verification needed. The approach, called Quantum Safe Bitcoin, aims to secure holdings using hash-based cryptography and puzzles. Concerns persist over coins with exposed public keys, estimated at about 6.04 million BTC.

Bitcoin \'Q-Day\' preparations accelerate as quantum threat solutions split into three tracks
The bitcoin industry and researchers are stepping up work to prepare for a potential future security threat from quantum computers, even though so-called Q-Day remains hypothetical. Efforts are moving on three tracks: quantum-resistant transactions that keep existing rules, upgrades to the bitcoin protocol to adopt new signatures, and stronger custody systems at exchanges and custodians. Each approach has limits, and the key issue is the gap between quantum computing progress and defensive readiness.

StarkWare researcher proposes way to block quantum attacks on bitcoin without soft fork
A StarkWare researcher has published a paper proposing a way to protect bitcoin transactions from quantum-computing attacks without a soft fork. The paper introduces “Quantum Safe Bitcoin,” or QSB, which aims to add quantum resistance using only existing legacy script constraints. It replaces elliptic-curve cryptography with a Binohash-based structure using one-time signatures and a new hash-to-signature puzzle. The author said the approach is costly, at about $75 to $150 per transaction.
