According to Cointelegraph, Project Eleven, a development company focused on post-quantum cryptography, has closed a $6 million funding round co-led by Variant Fund and quantum technology investment agency Quantonation. The funds will be used to develop tools against quantum computing attacks and protect digital assets such as Bitcoin. The company's first product, the Yellowpages encrypted registry, has completed a Cure 53 audit, allowing users to bind existing Bitcoin addresses with new quantum-resistant addresses without relying on on-chain activity.
