Author of LF and founder of ZeroTier here. I think my write up was a bit wordy so here is some more TL;DR:
LF is like etcd or consul (or so far just the data store aspects) but for decentralized systems that can be run by multiple parties across trust and organizational boundaries. It's an orchestration backend for decentralized apps.
We are going to use it to fully decentralize ZeroTier and for some specific enterprise customer projects, but others can use it for other stuff.
