The CPU power of Umbrel Home came in handy today as I performed a rescan of unspent UTXOs 4 times today. (1 time by mistake, forgetting to update conf file to prevent rescan)
I was told a UTXO rescan would take close to 24hours with a raspberry pi, but the Home crunched through it in 5.5 hours.
The reason for the multiple rescans?
The node onchain wallet was counting SPENT UTXO as unspent and was invalidating further onchain txns.
This was caused by several complications that were caused by multiple lightning channel openings and closings happening around the same time.
The real culprit that started causing issues was a opening txn that I did using unspent outputs.
I won't be doing this again, I will have low time preference and wait for confirmation from now on.
