    1//! # Pezcumulus
    2//!
    3//! Bizinikiwi provides a framework ([FRAME]) through which a blockchain node and runtime can easily
    4//! be created. Pezcumulus aims to extend the same approach to creation of Pezkuwi teyrchains.
    5//!
    6//! > Pezcumulus clouds are shaped sort of like dots; together they form a system that is intricate,
    7//! > beautiful and functional.
    8//!
    9//! ## Example: Runtime
    10//!
    11//! A Pezcumulus-based runtime is fairly similar to other [FRAME]-based runtimes. Most notably, the
    12//! following changes are applied to a normal FRAME-based runtime to make it a Pezcumulus-based
    13//! runtime:
    14//!
    15//! #### Pezcumulus Pallets
    16//!
    17//! A teyrchain runtime should use a number of pallets that are provided by Pezcumulus and
    18//! Bizinikiwi. Notably:
    19//!
    20//! - [`pezframe-system`](pezframe::prelude::pezframe_system), like all FRAME-based runtimes.
    21//! - [`pezcumulus_pezpallet_teyrchain_system`]
    22//! - [`teyrchain_info`]
    23#![doc = docify::embed!("./src/pezkuwi_sdk/pezcumulus.rs", system_pallets)]
    24//!
    25//! Given that all Pezcumulus-based runtimes use a simple Aura-based consensus mechanism, the
    26//! following pallets also need to be added:
    27//!
    28//! - [`pezpallet_timestamp`]
    29//! - [`pezpallet_aura`]
    30//! - [`pezcumulus_pezpallet_aura_ext`]
    31#![doc = docify::embed!("./src/pezkuwi_sdk/pezcumulus.rs", consensus_pallets)]
    32//!
    33//!
    34//! Finally, a separate macro, similar to
    35//! [`impl_runtime_api`](pezframe::runtime::prelude::impl_runtime_apis), which creates the default set
    36//! of runtime APIs, will generate the teyrchain runtime's validation runtime API, also known as
    37//! teyrchain validation function (PVF). Without this API, the relay chain is unable to validate
    38//! blocks produced by our teyrchain.
