The Go-Fil-Markets project provides modular implementations of the storage and retrieval market subsystems for the Filecoin network, aligning with the v1.0 and 1.1 Filecoin specifications. By modularizing these market components, the project supports diverse implementations while maintaining non-security-critical reuse. Key components include storagemarket and retrievalmarket for negotiating and executing data storage and retrieval deals, respectively, along with auxiliary components like filestore, pieceio, and piecestore to manage data pieces and deal information. The project interfaces with related components such as go-data-transfer for efficient data exchange. Go-Fil-Markets, which shares its issue tracker with Lotus, is open for contributions under dual licensing (Apache 2.0 and MIT), inviting community participation in the #fil-components channel on the Filecoin project chat. Relevant documentation and APIs are accessible via GoDoc, supporting ease of use and integration.
