Building a client for the betting contract

To make it easy to find match's IDs, deploy, and invest in contracts, we need to build a UI client. So let's get started with building a client, which will have two paths, that is, the home path to deploy contracts and bet on matches and the other path to find the list of matches. We will let users deploy and bet using their own offline accounts so that the entire process of betting happens in a decentralized manner and nobody can cheat.

Before we start building our client, make sure that you have testnet synced because Oraclize works only on Ethereum's testnet/mainnet and not on private networks. You can switch to testnet and start downloading the testnet blockchain by replacing the --dev option with the --testnet option. For example, take a look at the following:

geth --testnet --rpc --rpccorsdomain "*" --rpcaddr "0.0.0.0" --rpcport "8545"
