I would consider naming it something other than a common English phrase, honestly. I know it's the big trend these days, but it's making things incredibly hard to search for. Try searching for the messaging service "matrix" and the matrix client "vector". Insane amount of namespace collision there.

Best to go with something like Freechain or something so at least people can search for it.

"Freechain" is great. It passes the cognate test (sounds like "keychain," which it is), and the "free" part gives it the multiple meanings of both FOSS and freedom from surveillance. Euphony is pretty high, and it looks fairly low-noise on Google, too.

And chain even retains some connotations to "felon" ... ;-)

Seriously, though, "freechain" strikes a nice balance between being a new term, and hinting at what the use-case is.
