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.
