# zcash_history
Special implementation of Merkle mountain ranges (MMR) for Zcash!
[![Build Status](https://travis-ci.org/NikVolf/zcash-mmr.svg?branch=master)](https://travis-ci.org/NikVolf/zcash-mmr)
The main design goals of this MMR implementation are
- Allow zero-cache and avoid db callbacks. As it is implemented, calling side must just smartly pre-load MMR nodes from the database (about log2(tree length) for append, twice as much for deletion).
- Reuse as much logic between rust and c++ clients and place it here and librustzcash.
- Close to zero memory consumption.
