Sun Network Plan is an expansion plan for TRON main network ecosystem, including smart contract application oriented side chain(DAppChain), cross-chain communication and other expansion projects. DAppChain is a customizable side chain expansion project related to TRON smart contracts which allow DApps to run with extremely low energy consumption, high security, and high efficiency online operation. Sun Network is also designed to provide unlimited capacity for TRON main network to support the growing number of transactions.

By customizing the chain parameters, DAppChain can achieve a higher free energy limit, a cheaper energy burning, a faster consensus process, a shorter proposal effective interval, and a longer smart contract execution time limit.

Higher free Energy limit: Trading pressure on DAppChain will not affect the main chain and it decouples with TRON main chain. DAppChain provides a higher free energy limit, and even all transactions on the side chain are completely free.

Cheaper unit price for energy burning: By setting the energy unit price to be 1/100 or lower compares to the main chain, Dapp chain can provide developers with a very low-cost development experience.

Faster consensus: By adjusting the parameters, DAppChain can speed up the block production process, reduce the number of Witness, and speed up the transaction confirmed process. In the future, more consensus mechanisms will be added to further accelerate consensus.

Shorter proposal effective intervals: DAppChain can be configured to reduce the effective interval of a proposal from days to hours.

Longer smart contract execution time limit: With different parameters, DAppChain smart contract transaction can increase the maximum execution time of the transaction by 10 times or more from 50ms, thus supporting complex intelligent contract transactions.

Ensure the security of users' assets The first phase of DAppChain use the DPoS mechanism to ensure transaction consensus and correctness on side chain. With the smart contracts on both main chain and side chain, user assets can be secured and also correctly deposited and withdrew between different chains.

Complete ecosystem: Sunnetwork will provide a comprehensive set of development tools, which compatible with the main chain and support running on multiple platforms, which is aiming to reduce developer's learning costs and improve efficiency.
