Thanks for the mention! Steem Basic Income was designed to be a 100% voluntary crowdfunded basic income. Since it's self/crowd funded, it started out pretty small but has good momentum.

Arguably it's not universal since every subscription has to be sponsored by somebody, but there are ~4800 active Steemians receiving regular upvotes at least once per month, and more often when their subscription level is high enough. Two thirds of those are fully sponsored by somebody else (receiving upvotes without having paid anything to enroll).
