Lib.rs

Release

Polkadot SDK Stable 2412

lib.rs:

A BEEFY+MMR pallet combo.

While both BEEFY and Merkle Mountain Range (MMR) can be used separately, these tools were designed to work together in unison.

The pallet provides a standardized MMR Leaf format that can be used to bridge BEEFY+MMR-based networks (both standalone and Polkadot-like).

The MMR leaf contains:

1. Block number and parent block hash.
2. Merkle Tree Root Hash of next BEEFY validator set.
3. Arbitrary extra leaf data to be used by downstream pallets to include custom data.

and thanks to versioning can be easily updated in the future.
