交易如何確認?

iota.lib.py : get_inclusion_states

函數的註解:

Get the inclusion states of a set of transactions. This is for
determining if a transaction was accepted and confirmed by the
network or not. You can search for multiple tips (and thus,
milestones) to get past inclusion states of transactions.
:param transactions:
List of transactions you want to get the inclusion state for.
:param tips:
List of tips (including milestones) you want to search for the
inclusion state.

iota.lib.js : getLatestInclusion

var latestMilestone = nodeInfo.latestSolidSubtangleMilestone;

return self.getInclusionStates(hashes, Array(latestMilestone), callback);

可以看到需要Coo發起的交易hash , 才能正確的判斷某筆交易是確認的
