CTV and Cold Channels.
Today in Bitcoin, to make a channel, you must first receive Bitcoin on-chain and then transfer it to a channel with your partner interactively. This is a minimum of two transactions just to open a channel and the channel opening cannot be batched.
With CTV, channels can be hidden inside your pubKey so that when you're paid and the transaction is committed on-chain (can even be batched using only one UTXO), that on-chain commitment is sufficient to use your channel. No need to dump the channel details on-chain.
