The Sun Network is a blockchain-based platform designed to enhance the functionality of the TRON ecosystem. It aims to provide a decentralized infrastructure for developers to create and deploy applications, particularly in the realm of decentralized finance (DeFi) and non-fungible tokens (NFTs). By leveraging the power of blockchain technology, the Sun Network seeks to improve transaction speeds and reduce costs. Additionally, the Sun Network operates as a layer-2 solution, which means it works on top of the existing TRON blockchain to increase scalability. This allows for more efficient processing of transactions and supports a larger number of users and applications. Overall, the Sun Network plays a crucial role in expanding the capabilities of the TRON ecosystem.
