Blockchain Hypelerdger Indy节点-种子值

我正在玩indy sdk，在步骤3（）的演练演示中，Steward的种子值设置为“000000000000000000000000 Steward1”

如果我更改了它（或将其留空），我将得到一个错误。此外，在/tmp/indy/poo1.txn中，没有关于此特定值的信息

我的问题是，我们如何知道这是正确的值，以及如何获得它？

为什么它不起作用

000000000000000000000000 Steward1

是种子，它（给定默认密钥派生方法）生成DID

th7mptarzvrynpiads81y

。您可以使用

indy cli

（）

在您使用的网络中，DID

VsKV7grR1BUE29mG2Fm2kX

的所有者（即了解其相关私钥或种子的人）具有

steward

角色，该角色授予对分类账执行各种操作的权限。因此，如果修改种子，它将生成不同的DID，而DID将不具有执行教程中进一步使用的操作所需的权限（如在分类账上写入数据）

哪里是

0000000000000000000000001

来自哪里 根据您所说的，我假定您正在使用indy sdk repo运行池中的

indy node

实例中的预构建docker映像，下面是其中的一些实例 因此，简单的答案是

000000000000000000000000 Steward1

的配置是预烘焙的。请看用于构建印地泳池形象的图片。注意这些线

RUN awk '{if (index($1, "NETWORK_NAME") != 0) {print("NETWORK_NAME = \"sandbox\"")} else print($0)}' /etc/indy/indy_config.py> /tmp/indy_config.py
RUN mv /tmp/indy_config.py /etc/indy/indy_config.py

让我们看看这些文件里有什么

docker exec indylocalhost cat '/etc/indy/indy_config.py'
# Current network

# Disable stdout logging
enableStdOutLogging = False

# Directory to store ledger.
LEDGER_DIR = '/var/lib/indy'

# Directory to store logs.
LOG_DIR = '/var/log/indy'

# Directory to store keys.
KEYS_DIR = '/var/lib/indy'

# Directory to store genesis transactions files.
GENESIS_DIR = '/var/lib/indy'

# Directory to store backups.
BACKUP_DIR = '/var/lib/indy/backup'

# Directory to store plugins.
PLUGINS_DIR = '/var/lib/indy/plugins'

# Directory to store node info.
NODE_INFO_DIR = '/var/lib/indy'
NETWORK_NAME = 'sandbox'%                                      

这个

看起来像我们要找的。让我们看看有什么

docker exec indylocalhost ls '/var/lib/indy/sandbox'
data
domain_transactions_genesis
keys
node1_additional_info.json
node1_info.json
node1_version_info.json
node2_additional_info.json

node3_additional_info.json
node3_info.json
node3_version_info.json
node4_additional_info.json
node4_info.json
node4_version_info.json
pool_transactions_genesis

在区块链中，genesis文件通常是最初用于启动网络的文件，并可能使用一些数据填充网络。对于hyperledger indy，有4个“子分类账”包含不同类型的交易：

域

，

池

，

配置

，

审计

。

域

子分类账是包含诸如

DID

s、凭证模式或凭证定义之类的内容的子分类账。我们正在寻找一个DID，让我们看看文件域genesis文件

您可以看到DID

Th7MpTaRZVRYnPiabds81Y

是使用verkey

~7TYFEKW4GUAGBVCQPJIC在该分类账上硬编码的，该分类账与我们从seed
000000000000000000000000000000 Steward1
生成的内容相匹配。您还可以看到它的给定角色
“2”
。如果你深入挖掘，你可以在《印地全会》中找到一致的alg。indy使用的项目，角色ID
2
是
steward
种子是一个秘密值，当我们生成indy network的genesis事务时，我们使用来自该秘密种子值的公共信息/密钥

要知道写入种子值，要使用actors生成的密钥创建自定义网络，并生成pool_transactions_genesis和domain_transactions_genesis文件，必须使用indy plenum

您可以在以下教程中找到详细信息：

非常感谢您的回答。您好，帕特里克，我们创建了4个节点和5个客户端。这5位客户是谁？关于“{”reqSignature:{}，“txn:{”data:{”dest:“V4SGRU86Z58d6TV7PBUe6f”，“role:“0”，“verkey:“~CoRER63DVYnWZtK8uAzNbx”}，“metadata:{}，“type:“1”}，“txnMetadata:{”seqNo:“1}，“ver:“1”}”？@Polem定义了在分类账上创建的第一个DID。您可以注意到，所有后续事务都有“from:V4SGRU86Z58d6TV7PBUe6f”，因此V4SGRU86Z58d6TV7PBUe6f是这些后续事务的作者。您还可以注意到，在您指出的事务中，
V4SGRU86Z58d6TV7PBUe6f
DID被分配了作为受托人的角色
0
。如果我没记错的话，生成种子的DID
V4SGRU86Z58d6TV7PBUe6f
是
000000000000000000000000000000000000信任1
谢谢你的回答！是的，你是对的，但那是谁的身份？例如，根据我的研究，我假设DID
th7mptarzvrynpiads81y
是Node1的管理员，这引出了另一个问题。每个节点都有一个管理员/观察者角色吗？这些是docker中indy pool的genesis事务。它应该只用于发展。所以，这是一种“管理员”与高特权的角色。Afaik如果要运行参与共识的节点，则需要拥有DID和Steward角色。这里有更多信息。我不确定，但我认为观察员节点/角色也是如此。
