The Quantum Threat to Cryptocurrencies: What’s Real, What’s Hype, and What to Do About It
Google Quantum AI estimates that breaking the 256-bit elliptic curve cryptography protecting Bitcoin and Ethereum would require fewer than 500,000 physical qubits and roughly nine minutes of runtime on a superconducting architecture. The same day that paper landed, a separate…

A Viral Paper Claims Lattice-Based PQC Has “Fundamental Limitations” — The Arguments Are Old and the Conclusion Is Wrong
A Seoul National University paper arguing lattice-based cryptography has "fundamental limitations" is generating alarming headlines. The theoretical points are valid but well-known. What the paper actually demonstrates is why PQC migration should accelerate, not stall.

IonQ’s Q-Day Claim: What the Earnings Call Actually Said vs. the Panic It’s Feeding
IonQ's CEO told investors the company will reach the logical qubit count to "challenge RSA-2048" by 2028–2029. That's not the same as breaking encryption, and the Q-FUD machine is already running at full speed.
