Is there any transaction fee for Confidential Transactions in the Liquid Network?
In the UTXO model, Alice has 10 btc. She sends 1 btc to Bob, 8.999 btc as return change, and 0.001 as fee.
Input : 10 btc (Alice) Outputs: 1 btc (Bob) 8.999 btc (Alice)
The remaining balance of 0.001 is considered the fee but not recorded as a transaction output.
Is this the same for Confidential Transaction?
Input : C1 = Commit (10btc) Output: C2 = Commit (1 btc) C3 = Commit (8.999 btc) C4 = Commit (0.001 btc)
C1 = C2 + C3 + C4
If C4 is not there, then can we assume C4 = C1 - C2 - C3.
But is there any coinbase tx in Liquid to take the C4 fee? I 'm confused.
