I still do not quite understand how the project is technically realized, but the idea is successful. I am trusted by the fact that all XWIN funds are placed on the account of a smart contract and this is in the public domain.
The project is based on the ETH's blockchain. The use of it ensures the ability to easily access all the results and bets up to the first one made. It also ensures that nothing can be changed or altered by anyone after the bet was made, thus it eliminates the possibility of 3rd party frauds end guarantees that the conditions of the bet will stay exactly the way they were when you made it. That's about it in simple terms, you're welcome.
