Expand description
High-performance delta encoding for Ethereum consensus state.
eth_state_diff computes compact deltas between two beacon states and
efficiently reconstructs the target state by applying those deltas.
The crate is designed for consensus clients, archival storage, state synchronization, and historical state reconstruction.
Individual state components use specialized encodings chosen for their respective data structures, including sparse patches, circular buffer updates, packed bit vectors, and FIFO queue deltas.
Deltas are designed to serialize efficiently with rkyv, although the
library itself remains serialization-agnostic.
