Q:

How to find the block number of a transaction in a Wolfram Blockchain?

For example, in block 1004 of the Wolfram Blockchain, I can get the 4th transaction's ID by using the following code:-
tranID = BlockchainBlockData[1004]["TransactionList"][[4]]

Then I have f82c26a69b207f260f3a410d2931c8b749cb22a11b052b91ea79748835bd. It is an interesting image of a cube. You can try to see the image by typing:-
BlockchainGet[tranID]

My question is, if the situation is reversed, i.e. I have f82c26a69b207f260f3a410d2931c8b749cb22a11b052b91ea79748835bd but I don't have the block number 1004, how can I obtain the block number 1004? I tried below, but there's no luck.
tranData = BlockchainTransactionData[tranID];
tranData // Dataset
tranData["Inputs"] // Dataset
tranData["Outputs"] // Dataset

Many thanks!!

A:

Currently, BlockchainTransactionData doesn't return that information about the Wolfram blockchain. Note that blockchain functionalities are marked as experimental and that means they can change between releases. Blockchain functions introduced in v12 are more focused on Bitcoin and Ethereum.
