Radius is an innovative solution that addresses the issues of harmful MEV and censorship in the crypto space. It introduces a trustless shared sequencing layer that not only eliminates these problems but also generates economic value for rollups. The core technology behind Radius is PVDE (Practical Verifiable Delay Encryption), a cutting-edge cryptographic scheme based on zero-knowledge proofs. By implementing an encrypted mempool with PVDE, Radius ensures that transaction sequencing is completely trustless, preventing centralized sequencers from engaging in unfair practices such as frontrunning, sandwiching, and censoring user transactions.
