如果我不需要 Patricia 树中的值，是否需要提供分支节点？

[英]Do I need to supply the branch node if I don't need the value in it in a Patricia tree?

原文 2022-04-15 07:53:06 2 1 ethereum/ merkle-tree/ patricia-trie

For example, in this PATRICIA tree, if I want to prove that the key 'fc' has no value mapped to it, should I bring up the branch node stored the data value “b” even though I don't need the data value?例如，在这棵 PATRICIA 树中，如果我想证明键“fc”没有映射到它的值，我是否应该调出存储数据值“b”的分支节点，即使我不需要该数据值？

I guess I will use the branch anyway.我想无论如何我都会使用分支机构。
