A guessing competition using Ethereum
The aim of this competition is to use the 'jellybean' problem to explore Ethereum, smart contracts and dapp frontends
- Anyone can create a competition by uploading an image that shows a known quantity of uncountable things.
- The competition has a base entry value - how much it costs to place an initial bet
- Each subsequent bet is either disallowed or increases in costs
- A Competition has an end date
- Winners are revealed at the end date and winnings distributed
- If there multiple winners, the pot is divided amongst them equally.
- If there are no winners, the pot goes to the developers.
- A jackpot winner is determined by a winner guessing the exact number
- A winner is determined by the closest guess (without going over?) if there is no Jackpot winner.
- Developers create the competition, no image upload
- Simple bet cost setting
- One address one bet
- First bet after the end date triggers the end of the competition
