Episode notes
Migrate Active Funds Proactively
- Move coins from older or reused addresses to quantum-safe addresses before CRQCs arrive.
- Active users can secure funds today by never reusing or sharing the new public keys.
Post‑Quantum Signatures Break Current Limits
- Quantum-resistant signatures (lattice/hash-based) vary widely in size and assumptions and will increase transaction data significantly.
- Larger signatures will reduce throughput and strain node storage, splitting the community over trade-offs.
Prioritize UX And Education Early
- Invest in education, migration tooling, and UX redesign for wallets and custody systems now.
- Design upgrades with usable defaults and migration paths to avoid fracturing consensus later.
