Decentralized cloud computing, exemplified by Ankr, promotes sustainability through its node incentive model. By leveraging idle computing resources globally, Ankr reduces energy waste compared to traditional centralized providers like AWS. Its Proof-of-Useful-Work (PoUW) consensus redirects computational power to valuable tasks, enhancing efficiency. Node operators earn ANKR tokens for contributing resources, fostering a self-sustaining ecosystem. Rewards are tied to stakeholding, resource provision, and reputation, ensuring fair incentives. This decentralized approach minimizes reliance on energy-intensive data centers, aligning with eco-friendly principles. Ankr’s integration with blockchains like Ethereum and Polygon further optimizes resource use, supporting scalable, low-cost Web3 infrastructure. By incentivizing participation and reducing environmental impact, Ankr’s model drives sustainable innovation in cloud computing, paving the way for a greener digital future.
