qaci-contracts

This submodule contains all the Ethereum contracts and tests for MACI.

Contracts

MACI.sol

The main contract to which all on-chain interactions should occur.

It should not contain much code besides its constructor function. Rather, it should inherit from the following contracts, each of which defines a specific class of functions:

• Polls.sol

  • Defines all contract storage variables and constants. All data pertaining to a poll resides here.

• DomainObjs.sol

  • Defines structs that represent domain objects.

• External.sol

  • Defines functions that interact with external contracts (i.e. sign-up gatekeepers and voice credit oracles).

• VoterInteractions.sol

  • Defines functions for voters (i.e. sign up and publish messages).

• CoordinatorInteractions.sol

  • Defines functions for coordinators (i.e. process and tally votes).

• Getters.sol

  • Defines convenience view functions, particularly those which are more complex than reading a single variable.
