  Merkle tree encoding for matchId

Inspiration

Existing dapp sportcrypt.com, idea for contract version 2

What it does

For every event that people would like to bet on, a matchId is computed from the event details. This matchId is what is used to refer to the positions and orders. The matchId's encoding is chosen in such a way that the smart contract has access to all the parameters it needs with nothing needing to be added to the chain in advance, and no unnecessary storage usage.

How I built it

Doug came up with the merkle tree encoding format, and then we pair programmed the solidity implementation and a demo javascript dapp that uses it.

Challenges I ran into

Difficult to debug solidity code.

Accomplishments that I'm proud of

We got full end-to-end dapp betting solution prototyped, and proved the concept of merkle-tree encoded matchIds.

What's next for Scalable Betting Solution

Take these ideas and implement them for SportCrypt contract v2.
