不使用默认密钥的基板节点模板私有网络

如何解决不使用默认密钥的基板节点模板私有网络

我正在尝试构建一个 5 节点网络（Aura 和 GRANPA 的所有验证者和成员），我的目标是使用自定义密钥，而不是预定义的 Alice 等。因此添加了 SR和自定义规范 JSON 文件中的 ED 权限密钥。节点模板版本是来自 Github 的未更改的 V3。

我按照教程 (https://substrate.dev/docs/en/tutorials/start-a-private-network/customchain) 进行操作，但出现此错误：

要启动节点，我使用以下命令：

    --base-path /peer-data-1 \
    --chain local \
    --key-type aura \

自定义规范 JSON 文件是：

解决方法

自己找到了答案。

• 我颠倒了光环和爷爷权威 ID。确保AURA 使用 Sr25519 ss58 地址，爷爷使用 Ed25519 ss58 地址。
• 启动节点的代码有误，我添加了 --scheme Ed25519/Sr25519 以确保密钥库中添加的密钥正确。
