Votechain is a simple blockchain implementation specifically designed to record votes in an election. The chain does not hold other data about the election; only the votes cast. Another system, such as LockTheVote should be used to track elections, races, candidates, and verify voter identities.

"Transactions" on the chain are votes with fields to identify the race and selections. A vote is not a record of a full ballot, just a selection for a single race within an election.

Voter proofs are any value which uniquely differentiate a single voter from other voters. If an election does not require verifiable votes, voter proofs can even be blank or a single value. However, unique voter proof values can be used to verify inclusion in the election. The simplest voter proof value is a plain text identifer; such as an email or ID. This can easily be verified visually or programatically. On the opposite end of the spectrum, voter proofs can be non-interactive zero knowledge proofs. This kind of voter proof value allows voters (who hold their private key) to verify their vote was correctly recorded in the election while maintaining their anonymity.
