Reflections on the COLDCARD RNG Exploit
The Coldcard RNG exploit shows how silently degraded entropy can put hardware wallet users at risk. QRL v1 wallets remain secure with 384 bits of operating-system entropy, while the incident underscores the need for continuous audits, fail-closed randomness, and quantum-resistant cryptography.

Quantum-Safe Bitcoin Without a Soft Fork? It's Clever. But Read the Fine Print
A new paper from StarkWare presents a scheme for quantum-safe Bitcoin transactions using nothing but existing consensus rules. It is genuinely inventive. It is also, by its authors’ own admission, a last resort.
