The real target is ECDSA The migration nightmare Tech billionaires and crypto enthusiasts are currently questioning the long-term security of the Bitcoin network amid the quantum mayhem. However, according to former Mt. Gox CEO Mark Karpelès, the real threat to Bitcoin is the logistical nightmare of getting every user to upgrade. In a recent exchange on X (formerly Twitter), Karpelès has warned that successfully migrating the entire Bitcoin supply to a quantum-resistant standard will take years.

The real target is ECDSA As reported by U.Todya, Tesla and SpaceX CEO Elon Musk recently asked his Grok AI chatbot to estimate the probability of Bitcoin’s SHA-256 hashing algorithm being cracked by quantum computers by 2035. Grok estimated the risk at less than 10%, concluding that Bitcoin is safe “for now.” Karpelès, however, quickly pointed out that Musk and his AI were focusing on the wrong part of Bitcoin’s code. SHA-256 (used for mining) is highly resistant to quantum attacks, but the digital signatures used to authorize transactions are not.

If a fault-tolerant quantum computer running Shor’s algorithm reaches sufficient scale, it could theoretically derive a user’s private key from their exposed public key. This will make it possible for an attacker to forge signatures and steal funds. The migration nightmare Bitcoin developers can theoretically introduce new post-quantum signature schemes to the network via a soft fork, but deploying the code is…
