I am developing DAPP for increasing personal motivation. Idea is simple. You can create a promise backed by ETH deposit. If you succedded, you get the deposit back with additional bonus. If you failed, your deposit goes to a fund which is the source of bonuses.
Application is based on Ethereum blockchain. So all the money transfering is controlled by a smart contract. Winners get fair share of accumulated fund, based on promise complexity and deposit amount.
Currently there is working prototype wowmart.io
For test period it uses Kovan Ethereum Network, so all the money you use worth nothing. Any feedback is appreciated.
