A new IACR estimate sizes the secp256k1 break at 1,450 logical qubits and 40 million Toffoli gates

The algorithm-level numbers are the part of the estimate that can be recompiled onto any fault-tolerant machine, and the headline 25.7 days on 19,397 physical qubits belongs to the trapped-ion architecture its own authors proposed.
