zcash_mmr

Special implementation of merkle mountain ranges (MMR) for ZCash!

Build Status

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.

License

zcash_mmr is primarily distributed under the terms of both the MIT license and the Apache License (Version 2.0), at your choice.
