The New York Times published an investigation on Wednesday arguing that Adam Back, the British cryptographer who invented Hashcash, is the most likely person behind the Satoshi Nakamoto pseudonym used by Bitcoin’s creator. Back denied the claim, telling Cointelegraph he was referring reporters to his post on X after previously rejecting similar attempts to identify him as Satoshi. Back reiterated in the post that he is not Satoshi, adding that he “was early in laser focus on the positive societal implications of cryptography, online privacy and electronic cash, hence my ~1992 onwards active interest in applied research on ecash, privacy tech on cypherpunks list which led to hashcash and other ideas.” The investigation was conducted by John Carreyrou, a French-American investigative journalist best known for exposing the Theranos fraud. In the report, he claims that...

Will quantum-safe cryptography slow Ethereum? It is likely to affect gas fees, validator load and network efficiency, prompting Ethereum to pursue a broader redesign strategy. Ethereum relies on cryptographic systems that remain secure against classical computers. However, sufficiently advanced quantum machines could one day break these systems, potentially exposing private keys and putting billions of dollars in value at risk. Ethereum’s post-quantum initiative sends a clear message: there is no immediate threat, yet delaying action is not an option. Upgrading a global, decentralized network is a complex, multiyear effort that requires: Read more
