FOG is based on the Conditional Proof of Capacity (CPOC) consensus mechanism. Its features, such as anonymous transmission, anonymous transactions, the CPOC consensus algorithm, and the ring confidential transaction algorithm, further enhance the efficiency and privacy of the system. Through modular code design and the introduction of the Ethereum Virtual Machine to enable programmable smart contracts, FOG provides a more complete payment process and commercial viability, building a secure, free decentralized anonymous network.
