开发成本

介绍#

在区块链系统中，基于任何一条公链系统开发智能合约都涉及资源支出的开发成本。例如在网络上部署/调用智能合约，进行能量转换，质押/委托等操作都是需要花费一定的成本，不同区块链网络开发成本各不相同，在 PlatON 网络上开发智能合约的成本与以太坊及类似协议相近。本手册将以直观的格式进行分析比较，让用户对开发成本有一个比较清晰的认识。

概要#

本文将用表格的形式对比小型合约、中型合约和大型合约的不同开发成本，同时对 PlatON 与以太坊之间进行对比。在合约方面，使用一个简单的SET/GET功能的合约作为小型测试合约，中型合约示例将使用一个开源的微博客合约，而大型合约则是一个符合 PRC20 标准的智能合约。
