📰 The quantum-safe security thresholds for BTC and ETH have been pushed down again by a new paper. Researchers from institutions including the Ethereum Foundation, Theta Labs, and StarkWare found that the estimated amount of computation required for key steps in future quantum attacks is more than halved compared with the benchmark published by Google in March of this year.
🔥 The newly designed quantum circuit requires about 1,151 logical qubits and 1.3 million Toffoli gates, with a combined score of about 1.5 billion. The level Google previously provided was about 3 billion—this time it’s essentially cut in half.
💡 The researchers primarily optimized the point-addition operations repeatedly executed in Shor’s algorithm. In theory, if a quantum computer is strong enough, it could derive a private key from a public key and then forge transactions.
To be honest, this doesn’t mean BTC and ETH are already breakable by quantum computers. The paper still discusses a future attack model. But with the compute requirement lowered so much at once, it shows that the technical hurdles that once seemed far away are indeed being continuously shortened.
🤔 Do you think BTC and ETH developers should start pushing for post-quantum upgrades now, or wait until quantum hardware is closer to practical use?
