IONQ PRICES A BITCOIN-CURVE ATTACK DOWN TO 19,397 IONS AND 26 DAYS PER ATTEMPT

Summary from the TLDR Hardware newsletter

IonQ published a 70-page resource estimate concluding that a trapped-ion quantum computer with 19,397 physical qubits, built on its “Walking Cat” architecture, could compute a 256-bit elliptic-curve discrete logarithm on secp256k1, the curve securing Bitcoin and Ethereum, in about 25.7 days per attempt.
