Determine which transaction spent a Transaction Output I will explain my question through an example on the bitcoin testnet network.

I am looking at the output at index 0 of this transaction:

2a50bcc2ec49573ef816a95781b802766910f8690968236cf451cfc32defc491


I can tell through the bitcoin testnet block explorer that it was spent in this transaction:

7b1b3788ae4251d164031f899ba4e81f6371f70c24e71d38b03d44292ada9c81


Is there a way to use the bitcoind RPC methods to determine that it was 7b1b3... that was the transaction that spent this transaction output?

Thank you!
Bitcoind does not track this information as it is not necessary for normal validation, so no, this is not easily possible.
