BHD is a new crypto currency based on the CPoC(Conditioned Proof of Capacity) mechanism. By using hard disk as a consensus participant, it can significantly lower energy consumption and entry barrier, making mining of crypto currency safer, more decentralized and for everyone. BHD generates its unique value through mathematics and code. POC2 consensus mechanism;5-minute block generation time , the transaction speed is faster;8M block size to improve network efficiency;Zero knowledge proof will be added once whole network capacity reaches 3000P.Uses hard disk mining, anti-ASIC, mine without special equipment;Sustainable, low energy consumption, low noise;
