The operational token of the Theta protocol is the Theta Fuel. They can use it in conjunction with any other Theta protocol token. Relayers can be paid for sharing a video feed, or smart contracts can be deployed and interacted with on the blockchain.

Theta Fuel (TFUEL) is a cryptocurrency that operates within the Theta Network ecosystem, designed to support decentralized video streaming and content delivery. Theta Fuel serves as the native utility token of the network, facilitating various functions within the platform. It plays a crucial role in compensating users who share their excess bandwidth and computing resources to relay video content to other users.

Theta Fuel operates on a dual-token model alongside the Theta Token (THETA). While THETA is primarily used for governance and staking within the network, TFUEL is more focused on microtransactions and rewarding participants for their contributions to the Theta Network. Users can earn TFUEL by sharing their bandwidth, and content creators receive TFUEL as a form of payment for their contributions to the decentralized video streaming ecosystem. Overall, Theta Fuel plays a pivotal role in incentivizing and sustaining the decentralized infrastructure of the Theta Network.
