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.
