需要一个管理者节点来签署包含一些X，Y类型线性状态的交易。在没有state/contract cordapp的情况下，管理者可以签署该交易吗？该节点仍然具有flow-cordapps和流。
反序列化会不会有任何问题？监管机构确实需要存储状态，但他只需要签署交易即可。
答案 0 :(得分：1)
这是不可能的，但并非出于上述manish的原因。
从Corda 3开始，将交易发送给监管机构进行签名将产生java.io.NotSerializableException。
这种行为是有道理的-在无法看到输入和输出状态的情况下签署交易的目的是什么？如果您确实希望提供签名，则可以通过发送FilteredTransaction来解决该签名，在该状态中，所有状态均已被过滤掉，以及监管机构没有提供其类定义的任何其他组件。然后使用serviceHub.createSignatures(filteredTransaction)。
NB这是我尝试向交易对手发送SignedTransaction且其组件没有其类定义的组件时收到的堆栈跟踪的示例：

答案 1 :(得分：0)
否，这是不可能的。 CollectSignaturesFlow要求对方重写SendTransactionFlow来收集签名。仅当节点的cordapp具有由初始化的流时，这才可能。
