Solana protocol specs

This repository hosts protocol specifications of the Solana network, maintained by various protocol teams.

Organization

Section Description
core Basic concepts and data structures
consensus Blockchain consensus rules
runtime On-chain runtime environment (Sealevel)
p2p Validator network protocols
api Client-facing node APIs (e.g. JSON-RPC)

Community

This repo exists to define a single source of truth for consensus-critical sections of the protocol, such as verification and state transition rules.

The first long-term objective of the specification effort is to produce a complete and unambiguous reference for implementing a Solana validator.

Other documentation regarding widely adopted protocols may be added at the discretion of the Solana Foundation.

Reference Code

The solana_specs module contains Python 3.10 implementations of various specs.

Each unit is runnable as a test, like so:

python3.10 -m solana_specs.consensus.leader_schedule

The reference code is formatted using black.

Certain tests depend on test fixtures which are hosted on Git LFS. To download test fixtures, run:

git lfs pull
