This repository contains modular implementations of the storage and retrieval market subsystems of Filecoin. They are guided by the v1.0 and 1.1 Filecoin specification updates.
Separating implementations into a blockchain component and one or more mining and market components presents an opportunity to encourage implementation diversity while reusing non-security-critical components.
