Doing this securely requires a mempool node to be able to determine whether or not a given op is guaranteed to pay fees before rebroadcasting it.
This is quite hard to do, because it requires checking that the op does not depend on state that might change in the next block.
安全地执行此操作需要内存池节点能够确定给定的操作是否保证在重新广播之前支付费用。
这很难做到，因为它需要检查操作是否不依赖于可能在下一个块中更改的状态。
