The TRON Foundation officially introduced the Sun Network, a second-layer scalability solution for Tron (TRX), one of the largest platforms for deploying decentralized applications (dApps), on April 8th, 2019. The Sun Network aims to “incorporate a series of scaling projects” including sidechains for smart contract application development and “cross-chain communication,” which has been designed to “further expand the overall capacity,” or throughput, of the TRON blockchain network.
