Alice & Bob estimates that their cat-qubit quantum system could solve Bitcoin's 256-bit elliptic-curve cryptography in about 62 minutes using 29,588 physical qubits, significantly fewer than Google's previous estimate. This puts Bitcoin addresses with exposed public keys at risk, potentially threatening over 6 million BTC. However, the time to crack is longer than Bitcoin's 10-minute block interval, making theft before transaction confirmation challenging. Alice & Bob warns that quantum advances may arrive by the early 2030s and urges Bitcoin to adopt post-quantum security measures soon to protect funds.
Alice & Bob's quantum computing estimate for Bitcoin cryptography security comes as a backdrop to today's cryptocurrency market, where only 5 of 50 major cryptocurrencies on Pluang rose and 44 fell. Notable movers include SXP (Solar) down 46.27% at Rp37, BAL (Balancer) up 11.14% at Rp16.297, and UNI (Uniswap) down 10.72% at Rp117.854 with a Pluang order activity of 95% Sell / 5% Buy.
