Quadratic Voting smart contracts for Zilliqa

Part of the Zillacracy grant initiative.

Contracts 📜

Contracts are located in: /contract

There are 2 contracts:

• DecisionQueue.scilla (a queue for storing contract addresses)
• QVoting.scilla (quadratic voting logic)

QVoting

This is the real quadratic voting contract. Each contract represents one decision. This gets populated with options at creation. Rigth after creation the registration period starts, during which voters sign up to vote and receive their credits, based on the token set in the contract (CHECK NOTE BELOW). Once the registation period is over, the voting starts. Casting your vote is done by calling the vote transition, which will check your balance again, making sure you didn't move your tokens (you can't move tokens to a new account and register twice...) (again, CHECK NOTE BELOW).

DecisionQueue

This smart contract is simply a reference to the 'n latest' decision smart contracts. The contracts referenced here get posted on the web app (which doesn't exist right now). If you want to create an election and NOT have it be displayed on the web app, don't register it in the queue.

Tests 🧪

To run tests:

• Run the scilla-server docker container on localhost:4000 (get it using: https://github.com/Zilliqa/ceres)

Then run

npm run test

Generated outputs are in outputs/

• scillaCheckerOutput/ : The results from runnning the checker on the contracts
• testResults/ : The results of the tests on the contracts

NOTE

Currently the credit distribution is not decetralized. The contracts rely on the owner calling the owner_register transition. To do this in a decentralized manner we would need to access the token's contract balance from scilla, which currently isn't, but soon will, be supported. This means the register transition right now is simply for users to 'sign up' for the election. They will receive their credit balance as soon as the registration period is over and the election starts.

Possible extensions:

• Extend scillaTest into a standalone testing suite for scilla
• Add quadratic funding on top of QVoting contract
• Build new systems on top of QVoting once we can do contract calls in scilla (Waiting on @Zilliqa ❤️)
• QVote with NFTs. This would actually make credit checking and double voting prevention much easier. Idea is "if you have this NFT you have this amount of credits available to you"
