Crypto Researchers Halve Quantum Threat Estimates for Bitcoin and Ethereum
In a recent breakthrough that could reshape the timeline of quantum threats to digital assets, a team of cryptographic researchers has published a paper indicating that the projected vulnerability of Bitcoin and Ethereum to quantum attacks may be roughly half of what was previously estimated. The study, which was circulated to CoinDesk for early review, details how both human mathematicians and s…
