* We implemented that trait for the following encoding formats:
* [Ethereum-specific Compact Encoding](https://github.com/paradigmxyz/reth/blob/0d9b9a392d4196793736522f3fc2ac804991b45d/crates/codecs/derive/src/compact/mod.rs): A lot of Ethereum datatypes have unnecessary zeros when serialized, or optional (e.g. on empty hashes) which would be nice not to pay in storage costs.
* [Erigon](https://github.com/ledgerwatch/erigon/blob/12ee33a492f5d240458822d052820d9998653a63/docs/programmers_guide/db_walkthrough.MD) achieves that by having a `bitfield` set on Table "PlainState which adds a bitfield to Accounts.
* Akula expanded it for other tables and datatypes manually. It also saved some more space by storing the length of certain types (U256, u64) using the modular_bitfield crate, which compacts this information.

* We generalized it for all types, by writing a derive macro that autogenerates code for implementing the trait. It, also generates the interfaces required for fuzzing using ToB/test-fuzz:
