The team’s goal: encourage the transition to quantum-resistant wallets before a breakthrough in quantum tech puts user funds at risk.

While current quantum computers can’t yet crack Bitcoin’s cryptographic systems, future advancements could eventually break widely used protections like ECDSA and SHA-256. That could expose up to 25% of BTC, including coins in dormant legacy wallets. Lopp warned the fallout from such an attack would be catastrophic, flooding the market with stolen coins and eroding trust.

The proposed Bitcoin improvement plan urges holders and miners to migrate to post-quantum-secure addresses. If they don’t, the plan states, they risk permanent loss of access. The strategy frames security as a personal incentive: upgrade or lose your funds.

The proposal also references BIP 360, a quantum-safe upgrade designed by Anduro’s Hunter Beast, and includes contributions from developers like Marathon’s Michael B. Casey, who supports limiting vulnerable wallet activity to delay potential attacks.

While some analysts downplay the urgency, Lopp maintains the Bitcoin community must act early—before quantum computing becomes a real-world threat rather than a theoretical one.
