This is a work in progress - proceed with caution.

CommitRevealVoting is a generalized imlempentation of a commit reveal voting scheme. Only binary votes (e.g. Yes or No) are currently supported.

A few differences from other commit-reveal implementations:

• We don't implement partial locking. We assume that some form of whitelisting will be used to protect against sybil attacks.
• CommitRevealVoting itself does not expose state changing functions (they are internal). We assume that these will be wrapped in an inheriting contract, and that the inheriting contract will also handle the whitelisting.
• We allow anyone to reveal a vote if they know the correct salt. This opens up possibilities for a centralised (e.g. trusted system operator) or distributed (e.g. Shamir's Secret Sharing) vote revelation.
• We index the contracts by a bytes32 poll identifier. Inheriting contracts can use whatever index(es) they like and hash the ordered indexes into a unique bytes32.

TestCommitRevealVoting gives an example of how to use CommitRevealVoting with some naive whitelisting.
