Hi all!
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.
