History
Jack Grigg 7e89300db9 Move common package and dependency configs into workspace config 
The MSRV for the main crates is 1.65, which is higher than the Rust
version that stabilised workplace dependencies (1.64). The implicit MSRV
for the component crates is still lower than this, so we don't migrate
these crates.

zcash_history

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.
