erc777部署出现"execution reverted"
问题分析
因为在erc777部署的构造方法内，依赖erc1820,所以部署erc777前，需要先部署erc1820合约「只有新链，或者私链才需要新部署，对于大多数evm链都已经被提前部署好了，对于erc1820合约，是属于生态内共用的合约，具体实现可查看《erc1820技术实现》」
解决方法
部署erc1820
下面是直接从hardhat-erc1820扣取的代码，然后放到hardhat test工程内进行的部署

});注意，由于该“算法”没有chainid参与，所以需要发起交易的节点，禁用检查eip-155
节点启动时，需要添加启动参数
--rpc.allow-unprotected-txs以及rawTransaction数据中gasPrice为100gwei，
如果当前链设置的gasPrice大于此值，可以去某个BP节点本地进行交易发起，前提此BP节点启动参数也需要加上面参数重新启动
可能由于代码原因，发起后，可能导致全网gasPrice降低为100gwei，此时需要重启各个节点即可恢复
