## Merkle Tally Tree

`tallytree`

implements
merkle tally tree.

This is an implementation of Merkle Tally Tree in Rust. Merkle Tally Trees provide an efficient tally of an electronic vote. It scales to millions of votes, while still being able to prove efficiently to every voter that the tally was fair. Using merkle tally tree, you can create:

- Efficient proof that a vote was tallied in a result (vote included).
- Efficient proof that a vote was not tallied in a result (vote excluded).
- Efficient proof of number of ballots included in the tally (no ballot withholding).
