I am interested in figuring out at what height a transaction was mined, but I cannot find the right command to extract this information. Perhaps it's not possible?
My Bitcoin Core was not involved as sender or receiver of the transaction.

For a transaction that's not considered "yours" by the Bitcoin Core wallet, the only way to learn anything about it is through the optional transaction index.
If you have the transaction index enabled (-txindex
on the command line or txindex=1
in the configuration file), you can use the getrawtransaction
RPC with a txid to find the transaction in the chain. If you add a true
after the txid, it'll also report the transaction in decoded format, along with other information such as the number of confirmations. E.g. you'd run:
bitcoin-cli getrawtransaction f4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16 true
and get as response:
{
"in_active_chain": true,
"txid": "f4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16",

"time": 1231731025,

}
If you already know in which block the transaction was confirmed, you can verify it using the same RPC (even without transaction index) by adding the block hash as parameter:
bitcoin-cli getrawtransaction f4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16 true 00000000d1145790a8694403d4063f323d499e655c83426834d4ce2f8dd4a2ee
These commands can also be issued in the Bitcoin-Qt debug console.
txindex=1
in the configuration file. However, upon running getrawtransaction [txid] true
I am getting the following error: No such mempool transaction. Use -txindex or provide a block hash to enable blockchain transaction queries. Use gettransaction for wallet transactions. (code -5)
. Any ideas why this could be?
