Stacks Co-founder Summarizes Three Major Lessons from Coldcard Security Incident: Bitcoin Storage Should Be Diversified, Ecosystem Needs to Strengthen Security Cooperation

TechFlow news, August 2, Stacks co-founder Muneeb shared his views on the Coldcard wallet incident, summarizing lessons from three aspects: Bitcoin storage, quantum computing threats, and ecosystem security construction. Regarding Bitcoin storage strategies, he pointed out that many industry security experts are not even familiar with Coldcard, and top security research institutions may not have fully audited its code. Muneeb believes that the best solution in the future should be asset diversification, rather than concentrating all funds in a single solution, and suggested:

1. Allocate 20%-30% of BTC to ETFs, such as BlackRock's Bitcoin ETF IBIT, to obtain professional custody and regulatory protection;

2. Use 40%-50% of BTC for multisig solutions similar to Casa, such as a three-key model, distributing keys across security companies, mobile devices, and hardware wallets;

3. Use 20%-30% of BTC for more advanced self-custody solutions, combining different hardware wallets and different entropy sources.

Regarding the quantum computing threat, Muneeb stated that after quantum computers break through existing encryption systems in the future, Bitcoin users may experience a shock similar to "BTC in cold wallets suddenly being transferred away." The quantum threat is real, and the industry should prepare in advance rather than underestimate technological progress, especially against the backdrop of large language models accelerating breakthroughs in scientific research.
