Notice

This package has been relocated to the Sovereign monorepo. The most recent changes to the repo can be found at that location.

JMT

This crate is an implementation of a jellyfish merkle tree, made generic over the hash function and digest size. It is based on the implementation by Aptos-Labs, but has been modified to be used as dependency-minimized standalone package (on top of addition of generics).

Warning

This code has not been audited and is still under development. Do not use in a production setting.

Feature Flags

  • "metrics": enable Prometheus metrics. The following counters are enabled.

    • JELLYFISH_LEAF_ENCODED_BYTES: the number of bytes serialized as leaves
    • JELLYFISH_INTERNAL_ENCODED_BYTES: the number of bytes serialized as internal nodes
    • JELLYFISH_LEAF_COUNT: the number of leaves in the tree
    • JELLYFISH_LEAF_DELETION_COUNT: the number of leaves deleted from the tree

  • "rayon" uses rayon to parallelize insertions, giving improved performance on multi-core systems

  • "fuzzing" enables additional functionality for property-based testing using the proptest library
