This is a slightly modified version of a transaction. (privacy reasons)

Edit: Sorry, but turns out there is another tx besides this tx:

"txid": "485579924ce684df7aa7a9861abb4b858a8d917aa1df94bf3a234368a250516",
            "version": 1,
            "locktime": 0,
            "vin": [
                {
                    "coinbase": "033934050d00456c69676975730054ca7075fabe6d6de7cbb1e6f6ca2ed785b50b0bea44f69887952d5e359f5f7478ff677e2e9064f2400000000000000002f737333382f0050dd79739f7f000094fe0a00",
                    "sequence": 4294967295,
                    "n": 0
                }
            ],
            "vout": [
             .
             .
             .
             73 => [
              EXPECTED VALUE!
             ]

Now I am thoroughly confused :( . Please feel free to link to some relevant reading materials..

Questions:

vin['vout'] equals 73 here. Why is this, considering that there is only 1 vout element ? I have the impression that the value of vout (in vin) points to the index of the vout (vout['n']). Is that wrong ? If so what does it point to

Also what does vin['n'] points to exactly ?

P.S: I have read In getrawtransaction, what is the vout integer in the vin list? - which explains transactions in great detail.. but I couldn't figureout from there what vin['vout'] integer value is precisely

It points to the output 'n' in the transaction which that input spends from, not the spending one.

  • ok, since everything is stored as transaction, this makes a whole lot sense. Thanks. Just please clarify whether It here refers to vin['vout'] OR vin ['n'] ?
