介绍

任何区块链的智能合约开发都涉及资源支出的开发成本。但是，在TRON区块链上开发智能合约远比以太坊和类似协议便宜。本指南以用户友好的格式进行比较。如果您希望估算开发智能合约的能源成本，请转到 Tron Station ，它有能量和带宽工具可以帮助您。

概要

下表对比了小型合同的开发成本，中型合同以及TRON和以太坊之间的大型合同。两个示例小合同是简单存储合同和斐波纳契合同。中型合同示例是一个名为zombiefactory的修改后的加密僵尸合同，而大型合同是另一个名为zombieownership的修改后的加密僵尸合同。带宽和能量消耗发生的三种情况概括为TRON-1，TRON-2和TRON-3：

图表表示

TRON-1：不使用来自质押代币的任何带宽或能量
TRON-1 = 能源费+带宽费
TRON-2：仅使用来自质押代币免费带宽或带宽

TRON-2 = TRON-1 - 免费带宽配额 - 质押带宽配额
TRON-3：使用来自质押代币的带宽和能量
TRON-3 = TRON-2 - 冷冻能源配额

#质押需要多少TRX才能在主网上自由部署？

以下数字来自于2014年10月23日的测试，其中TotalEnergyWeight为2,127,263。

我们从冷冻100 TRX获得的能量是=（100/2127263）* 50,000,000,0000 = 23504380。

获得的能量=为获得能量而质押的TRX /为在整个网络中获得能量而质押的总TRX * 50,000,000,000

基于这样的质押代币池大小，

* 为了部署一份小合同，我们需要质押2-2.5 TRX;

* 用5-20 TRX质押足以免费部署中型合约;

* 对于一份大合同，这个数字大约是50 TRX。

**请注意，能量获得（energyLimit）是基于totalEnergyWeight的动态。**
