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.
- filestore: a submodule branch that is a side effect of using the ffi to generate commP
- pieceio: utilities that take IPLD graphs and turn them into pieces
- piecestore:
- storage market: for finding, negotiating, and consummating deals to store data between clients and providers (storage miners)
- retrieval market: for finding, negotiating, and consummating deals to retrieve data between clients and providers (retrieval miners)
Related components in other repos:
- data transfer: for exchanging piece data between clients and miners, used by storage & retrieval market modules.
- The Markets in Filecoin section of the Filecoin Specification contains the canonical spec
- The Storage Market Module design doc is a more specific overview of these component implementations
