Quantum threat gets real: Ethereum Foundation prioritizes security with leanVM and PQ signatures

Earlier in January, the Ethereum Foundation formally elevated post-quantum security to a strategic priority, creating a dedicated Post-Quantum team. What to know : Quantum computing has long been a distant, theoretical threat to blockchain cryptography. But over recent months, that calculus is shifting rapidly. Earlier in January, the Ethereum Foundation formally elevated post-quantum security to a strategic priority , creating a dedicated Post-Quantum (PQ) team to drive research, tooling and real-world upgrades to protect the network’s cryptographic foundations.
