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

The increasing reality of quantum computing threats has prompted the Ethereum Foundation to take significant steps towards enhancing the security of its blockchain infrastructure. As a proactive measure, they are prioritizing the implementation of leanVM, a streamlined virtual machine designed for greater efficiency and robustness in smart contract execution. In addition, the adoption of post-quantum (PQ) signatures reflects their commitment to safeguarding user transactions and data against potential vulnerabilities posed by emerging quantum technologies. By focusing on these advanced security measures, the Ethereum Foundation aims to ensure the continued integrity and trustworthiness of its platform in an evolving technological landscape. source: https://www.coindesk.com/tech/2026/02/01/quantum-threat-gets-real-ethereum-foundation-prioritizes-security-with-leanvm-and-pq-signatures
