its Lightspark's answer to the ln challenges. (inbound liquidity, always online, etc) the company is run by David Markus (ex paypal, libra project at facebook) Technically its state-channels with a few tradeoffs. You can't unilaterally exit without permission as of today from what I understand. Just listened to Matt C on TFTC podcast and he seemed to think it would work well for nostr zaps temporarily and then upgrade to say phoenix once you had enough to open a channel. Similar to Zeus's new upgrade of using ecash to receive immediately without a channel then graduating to a ln channel.
