Inbound liquidity is necessary to receive funds, it is tricky to explain, and the protocol was missing some crucial parts to make it seamless for inexperienced users. By going too fast too early, we would have spent a considerable amount of time providing support to users who couldn’t receive money right after having opened a channel (while all the money is on their side). Dual funding and liquidity advertisement (discussed during the Lightning Summit last Nov and scheduled for LN 1.1) will finally bring the tools allowing us to address this at scale and in a reasonably user-friendly way.
