//! This crate contains all the fundamental building blocks for the Griffin
//! ledger, runtime, and wallet.
//!
//! It was initially based on
//! [tuxedo_core](https://off-narrative-labs.github.io/Tuxedo/tuxedo_core/index.html),
//! and it now includes a clone of six crates from the
//! [Pallas](https://github.com/txpipe/pallas) suite, with modifications in
//! order to be used in a `no-std` setting.
//!
//! The Core main purpose is to bring the Griffin node to life. The node is
//! based on Substrate / Polkadot SDK, and the instructions to make it run can
//! be found
//! [here](https://github.com/txpipe/griffin/tree/main?tab=readme-ov-file#griffin).
