I have an example of a transaction. I deleted some fields which don’t play any role for my question. Also I reduced large hashes and IDs. So here it is:{ "txid": "8d554", "vin": [ { "txid": "d3117", "vout": 0 } ], "vout": [ { "value": 1.99995000,"address":"mrL8SS", "n": 0 }, { "value": 3.00000000, "address":"mtK8r", "n": 1 } ] } From this transaction I can find out which transaction was used for paying outputs of this transaction. Because those transaction is in “vin” field. Its txID is “d3117”. So if i want i will be able to find this transaction by using bitcoin client RPC API: bitcoin-cli gettransaction d3117. But what if i want to find out, which transaction used THIS transaction as input? Could you guys please tell me, if it’s possible or not?
