Why now

Quantum computing capabilities are advancing, creating urgency for quantum-resistant Bitcoin solutions.
New proposals like QSB provide immediate fallback options while broader upgrades are debated.
Experts estimate a 3-5 year window to implement effective quantum defenses before risks escalate.

Why it matters

Quantum computing poses a future threat to Bitcoin's cryptographic security, risking transaction integrity.
A solution that avoids protocol changes reduces community coordination challenges and upgrade risks.
Legacy wallets are particularly vulnerable, highlighting the need for timely upgrades to protect large BTC holdings.

Recurring claims

Bitcoin can be made quantum-safe without protocol upgrades or softforks using hash-based security schemes.
Quantum-safe transactions under the new scheme cost between $75 and $200 per transaction in computing power.
Bitcoin has a 3-5 year window to prepare for quantum computing threats, focusing on upgrading legacy wallets.
