4/ Transaction Simulation:
For certain job types, node response transactions can now be simulated off-chain before their transmission on-chain.
This feature can help save on gas costs during times of high demand by minimizing the occurrence of on-chain reverts.
4/交易模拟：
对于某些作业类型，节点响应事务现在可以在链上传输之前进行链外模拟。
此功能可通过最大限度地减少链上故障的发生，帮助在高需求时期节省汽油成本。
