GADDS

GADDS provides a decentralized platform for managing, sharing, and verifying large volumes of heterogeneous digital research data while enforcing metadata integrity and supporting the Findable, Accessible, Interoperable, and Reusable (FAIR) principles.

Key Features:

• Blockchain-Based Metadata Quality Control System: Uses blockchain to maintain an immutable record of metadata changes for integrity and provenance tracking.
• Private Cloud-Like Storage System: Offers secure, private cloud–style storage for controlled data retention and privacy compliance.
• Version Control System: Integrates version control to track dataset changes and preserve modification history.
• Containerized Technologies: Employs containerized technologies to enable scalable deployment and reduced hardware requirements.
• Decentralized Trust via Metadata Transparency: Leverages transparent metadata management to establish decentralized trust for data sharing and collaboration.

Scientific Applications:

• Cross-disciplinary research collaborations: Manages and harmonizes diverse datasets across disciplines by enforcing FAIR metadata and provenance.
• Engineered living material research: Applied at the Hybrid Technology Hub, University of Oslo, to support data sharing and collaboration in engineered living material technology.

Methodology:

Implements a decentralized data management approach that leverages blockchain for metadata quality control and uses containerized technologies for scalable deployment across computing environments.
