## Simple opsec with SBW and hosted channels (HC)

1. Setup on your home personal node or a friend node a server for hosted channels  using @fiatjaf [Poncho](https://github.com/fiatjaf/poncho) and [Cliche](https://github.com/fiatjaf/cliche). Or use any other HCP (hosted channel provider) available.
2. Use [SBW.app](https://github.com/btcontract/wallet/) to open a HC with your personal HC server, or many HCs.

Anytime you want to hide your sats from that HC, you just have to remove it from your channel list. Go to Lightning, swipe to the right the channel you want to hide and select remove.

Anytime you want it back, just scan again that HC node address and select "use HC". Done, the channel is back again and your sats in it. Funds are safu.

Nobody could see / know about that channel if is not there.
This could be a simple opsec option at hand.

I still haven't read that paper, it's on my to-do list. That same passage was the one that jumped out at me, though.

Leaving aside everything related to artificial credit expansion, somehow, radically reducing transactions costs in the global financial system is not supposed to have any productivity effect.
