Archival and Versioning
The marketplace design includes provisions for long-term storage options, such as integration with Filecoin, which complements IPFS with economic incentives for data persistence. IPFS also supports multiple versions through unique CIDs, enabling reversion to prior states. For instance, a dataset might have versions v1.0 and v1.1, each immutable and verifiable. This ensures data provenance, allowing consumers to access specific iterations.

The versioning system serves several important functions in the data lifecycle:
It preserves the historical record of dataset evolution, crucial for research reproducibility
It enables consumers to access specific versions that match their requirements
It allows providers to update datasets while maintaining backwards compatibility
It creates a foundation for differential pricing based on version recency or features
