John Carvalo recently pointed out that not every implementation accepts zero-conf channels, but they are useful. Roasbeef also recently noted that they're not spec'd. How do you all do it? Here's a strawman proposal: 1. Assign a new feature bit "I accept zeroconf channels". 2. If both negotiate this, you can send update_add_htlc (etc) *before* funding_locked without the peer getting upset. 3. Nodes are advised *not* to forward HTLCs from an unconfirmed channel unless they have explicit reason to trust that node (they can still send *out* that channel, because that's not their problem!). It's a pretty simple change, TBH (this zeroconf feature would also create a new set of channel_types, altering that PR). I can draft something this week? Thanks! Rusty.
