I am using it to organize Lottery for nonprofits:
"Only 3 days left to participate to the test run of the Green Lottery.
This week 46 % of the pot will be send to Orinoco Verde (orinocoverde) a Venezuelan nonprofit, member of the SEEDS community, managed by @Danigorfest.

Send 8 TLOS to the account greenlottery to participate. You could be the co-winner of the pot with Orinoco Verde and win 46 % of the pot, too.

Next week we will support CLEAN PLANET (account clean4planet), another member of the SEEDS community. CLEAN PLANET rewards people collecting trashes, all over the world.

Thank’s to Gtreen Lottery and the Telos blockchain community, a new ngo will win every week to achieve its goals.

All results and transactions are public on the Telos blockchain.

Did you subscribe to the Universal basic income on Telos?

It is a financial app but with a lot of influence on the social organization of work.
