Grouping a solidity based ethereum contract application built for a Master Thesis in Computer Science titled Secure Random Grouping for Blockchain based Voting.
Spin up a local blockchain using ganache. Download the app and create a new blockchain.
Set the number of accounts to at least 13.
Make sure you have node v10.5.0, otherwise get nvm and run
nvm install 10.5
Also have truffle installed:
npm i -g truffle@latest
Install dependencies
npm install
You need to have the ethereum-bridge running to communicate with the provable oracle
npx ethereum-bridge -a 9 -H 127.0.0.1 -p 7545 --dev
Add for example --oar 0x6f485C8BF6fc43eA212E93BBF8ce046C7f1cb475 if you ran the command above before and want to use the same address as stated below:
The bridge will print out the address of the oracle contract.
OAR = OraclizeAddrResolverI(0x6f485C8BF6fc43eA212E93BBF8ce046C7f1cb475);
Copy paste it into the constructor function of the contract ShuffleAndRoundRobin so that it knows where to connect.
To execute tests you can run
truffle test
To get debug events shown
truffle test --show-events
To run it simply execute
truffle migrate
