Bitcoin’s Quantum Risk Is Closer Than You Think – Because It Doesn’t Use RSA

Most quantum-risk-to-Bitcoin analyses rehash RSA-2048 timelines. They're missing the point. Bitcoin doesn't use RSA. It uses 256-bit ECC - and Shor's algorithm will break that first. Scan the qua...

Pinnacle Architecture: 100,000 Qubits to Break RSA-2048, but at What Cost?

Iceberg Quantum's Pinnacle Architecture paper claims RSA-2048 can be factored with fewer than 100,000 physical qubits - a genuine 10× reduction over the previous state of the art - by replacing sur...
