我尝试了 Quorum 7 节点示例，它运行完美。但我发现./raft-init.sh正在为每个节点编写运行创世块。

代码 ：

如您所见Writing genesis block，正在为每个节点完成。那么每个节点都有自己的区块链吗？7 个节点的例子不是应该展示 7 个具有不同“职责”的不同节点如何共存并与一个区块链一起运行吗？

是的，这背后的原因是 Quorum 使用 7 节点分类帐和密钥路径 quorum-examples/examples/7nodes/keys。但是如果你看到 Quorum 的架构，请关注路径
1.quorum-examples/examples/7nodes/qdata/dd1 2.quorum
-examples/examples/7nodes/qdata/dd2

在上面的路径中有带有permissioned-nodes.json 的geth 节点。参见enode部分。这个encode是Peers encode ID，我们在以太坊中一般使用它来通过GETH链添加peer。
以太坊 geth 通过确定通道 ID 提供了通过 geth 创建私有节点的架构。

如果您从对等方中删除此编码，则将不存在 Genesis 的写入。

Quorum 使用 istanbul 算法来决定网络上的交易。这就是为什么 Quorum 团队使用第 7 个对等点，它们各自的编码共享。

希望你能明白我的意思。
