IonQ publishes end-to-end blueprint to break secp256k1 signatures with ~20k physical qubits

IonQ detailed a compiled, fault-tolerant resource estimate for running Shor’s algorithm on secp256k1, projecting ~19,397 physical qubits and ~25.7 days per attempt with ~63% success probability. The company aligned requirements to its roadmap targeting the necessary systems around 2028.
