Accel (acceleration chain) is a blockchain project built with Xiaoyu Accelerator as a node to share idle network bandwidth, storage resources and computing power. Accel (acceleration chain) adopts the PoS algorithm as the consensus mechanism, and based on the user's hardware configuration, bandwidth quality, transmission data volume, storage size, computing power, online time and other factors, the contribution degree is comprehensively calculated for incentives. Accel (acceleration chain) also provides distributed CDN network acceleration, computing power and other services, and we will build a Dapp ecosystem to create a closed loop of consumption to achieve truly sustainable development.
