Anthropic's unreleased Claude Mythos Preview AI model found previously unknown weaknesses in HAWK post-quantum cryptographic algorithm and a reduced-round version of AES encryption, completing analysis in 60 hours that human experts failed to discover over years of review.
Ethereum co-founder Vitalik Buterin published an updated roadmap for 'Lean Ethereum,' a comprehensive 3-4 year rebuild that will replace nearly every major component of the protocol. The overhaul, described as the network's biggest upgrade since the Merge, prioritizes quantum resistance and enhanced validator privacy.
In a research note published May 3, 2026, Galaxy Digital Research Director Alex Thorn reported that the Bitcoin community is coalescing around a consensus to leave Satoshi Nakamoto's coins untouched while preparing for quantum computing threats through post-quantum cryptography adoption.
Within 48 hours of BIP-361, three competing approaches surface. Adam Back argues at Paris Blockchain Week for optional upgrades over forced freezes. BitMEX Research proposes a reactive "canary fund" that only triggers a freeze if a quantum attack is proven on-chain. Justin Sun announces TRON will be the first major chain to deploy NIST post-quantum signatures on mainnet, though no technical documentation follows.
Google publishes a call to action urging governments and industry to prepare for the end of current encryption standards, warning that a cryptographically relevant quantum computer is “not forever a decade away” and that the transition to post-quantum cryptography must begin now.
