我服务器版本是Ubuntu 22，我geth版本是最新版本1.15，我想搭建一个POA共识，我的json文件如下{ "config": { "chainId": 991020, "homesteadBlock": 0, "eip150Block": 0, "eip155Block": 0, "eip158Block": 0, "byzantiumBlock": 0, "constantinopleBlock": 0, "petersburgBlock": 0, "istanbulBlock": 0, "berlinBlock": 0, "londonBlock": 0, "terminalTotalDifficulty":0, "clique": { "period": 3, "epoch": 30000 } }, "difficulty": "0x1", "gasLimit": "0x3000000", "extradata": "0x00000000000000000000000000000000000000000000000000000000000000006e4ca1282ff4295c03655980d511512742bb00400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000", "alloc": { "0x918f2aF5376a8B83a099a97DAB18b8ee63CFbC7a": { "balance": "100000000000000000000000000" } } } 我本来没有"terminalTotalDifficulty"这个属性 terminalTotalDifficulty加完他就变成了POS 但是我启动的时候报错,我加完确实链起来了 log里边没有报错 但是我进入控制台一直不产块 有没有大神告诉我一下 为什么
