XELIS is the world's first BlockDAG with privacy, speed, scalability, and smart contracts. Founded in 2021, it aims to provide a secure, private, and scalable cryptocurrency. It features a new hashing algorithm, blockDAG structure, and privacy-enhancing technologies. The next milestone is the implementation of a smart contracts engine, powered by a new Virtual Machine called XVM. XELIS is built using Rust and Tokio async runtime for speed, efficiency, and security.
