The operational token of the Theta protocol. TFUEL powers on-chain operations like payments to relayers for sharing a video stream, or for deploying or interacting with smart contracts. Relayers earn TFUEL for every video stream they relay to other users on the network. You can think of Theta Fuel as the 'gas' of the protocol. At Mainnet launch on March 15th, TFUEL will be created as a native token on the Theta blockchain.
FNKOS is a fog computing-based blockchain operating system designed to make the best use of the edge computing resources such as idle hardware network and storage resources. The fog blockchain was built on the basis of a PoC (Proof of Contribution) consensus algorithm: nodes get FNKOS incentives according to their contribution in the fog blockchain based on network flow, storage volume, computational capacity.
