About

YOUChain is focused on carrying out large-scale commercial applications through its YPoS consensus mechanism and investment model. YOUChain aims to create a public blockchain with high-performance and scalability to achieve its vision of “One Mobile Device One Node, Everyone Can Participate”. YOUChain's founding team is reportedly from Alibaba, Tencent and BITMAIN. It has the following features: - YPoS, a BFT consensus algorithm based on VRF and PoS, reportedly supports a large number of nodes to conduct consensus. - Super routing, a P2P system made for both home broadband and mobile network, reportedly helps to enhance the efficiency of complex communication environments. - Intelligent sharding reportedly enhances scalability. - Any mobile device can theoretically become a node in the network to achieve decentralization.
