PoolTogether: No-loss Lottery

Officially launched in September 2019, PoolTogether is an Ethereum-based no-loss lottery system. Initially designed by governments to combat inflation and encourage saving, no-loss lotteries have since been adopted by corporate enterprises.  

The basic structure of no-loss lotteries is as follows: users purchase tickets, with payments subsequently directed into a savings instrument. After some period, the yield earned is distributed to a single ticket holder, with the principal returned on a pro-rata basis. The savings instrument, duration, and fee structure are subject to change according to the issuer’s preference.
