Through this interface, developers can modify the configuration parameters of the blockchain, such as block rewards, mining  difficulty, etc. Additionally, this interface can be used to query the current running state and parameters of the blockchain. The ParamSet interface plays an important role in blockchain technology because it allows participants in the network to jointly maintain and improve the blockchain system, ensuring the healthy development of the blockchain network. On smart contract platforms such as Ethereum, the ParamSet interface usually exists in the form of a contract, providing developers with a way to set and get blockchain parameters. By using the ParamSet interface, developers can flexibly adjust the blockchain."}]}],"pr":"581805f5fba2e9df56600761f9c6b64f58780c7e7e1be7adb0f38d58c3ab3cef"}
