-At any point in time, Alice and Bob may have dozens or even hundreds of HTLCs across a single channel. Each HTLC would be offered and added to the commitment transaction as an additional output. A commitment transaction would therefore always have 2 outputs for the channel partner balances and any number of HTLC outputs, one per HTLC.

 As we will see in the next section, the maximum is only for _pending_ HTLCs, since once an HTLC is fulfilled (or fails due to timeout/error), it is removed from the commitment transaction.
