This is also a central focus for us here at Indranet. I'm hoping that the system will enable me to fall back into the woodwork once it's up and running.
Satoshi rightly made the network fully transparent, giving us a fully auditable supply, but to fully qualify as cash there has to be strong anonymity. LN goes some way towards this, but I think that it is a clear case where there needs to be other types of Layer 2 systems running on top of Bitcoin specifically for this case. Liquid, RGB, Fedimint, Cashu, these are tippy toeing in the right direction but I'm still to see a L2 that obsoletes Monero. That will help a lot - and I do believe it will require a fully functioning, large scale anonymising p2p network layer first. Thus, Indranet!
