Intentionally reveal unspent transaction outputs (UTXOs)
As per this discussion I learned it is not possible in Monero to count the total unspent transaction outputs (UTXOs) in the blockchain to verify the total coin supply. I can understand that this is not even needed since the total coin supply can be…
