ABSTRACT
Data sharing is an integral component of scientific research and associated publications. Researchers have the ability to extend and build upon prior research when they are able to efficiently access, validate, and verify the data referenced. Facilitating the future reuse of data in a secure and independently verifiable manner is critical to the advancement of research. Open Science Chain (OSC) allows a broad set of researchers to efficiently share metadata and easily verify authenticity of their scientific datasets in a secure manner, while preserving provenance and lineage information.
OSC is a web based cyberinfrastructure platform built using distributed ledger technologies that allows researchers to provide metadata and verification information about their scientific datasets and update this information as the datasets change and evolve over time in an auditable manner. The researchers are able to search, verify and validate scientific datasets and link datasets to show lineage information. OSC features a web-based portal with user-friendly interfaces for metadata registration, data search and verification capability. OSC has been designed and implemented using real world scientific datasets from a diverse set of use cases ensuring the broad applicability across scientific domains. OSC enables sharing and verification of datasets among wider research communities including large facilities, smaller labs, individual researchers and students while promoting good data documentation practices. OSC increases the confidence of the scientific results and promotes data sharing, which in turn increases productivity and promotes good science.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
This project provided a unique blockchain-based solution for managing the integrity and provenance of research artifacts used in collaborative research. The Open Science Chain (OSC) project has developed a cyberinfrastructure solution using consortium blockchain technologies to store and manage the integrity and metadata provenance information of research artifacts. An easy-to-use portal and python-based command line utility were developed to lower the barrier of access to using the blockchain solution.
The OSC portal allows researchers to share the metadata provenance of research datasets, perform verification of other users' data and provide feedback to highlight potential issues with the data or metadata of published research. Researchers can link external repositories (such as GitHub or GitLab) to create a detailed workflow of their scientific experiment, linking multiple sources of data and computational code used in their published results. The entire workflow is stored in the blockchain which provides a timestamped, immutable version of the metadata provenance. The command line utility enables automated and seamless communication between familiar working environments of the researcher and OSC, allowing the researchers to use OSC from their own laptop and other computing resources such as remote servers or HPC clusters. As a result, researchers can integrate with OSC to manage research artifacts during various stages of their computational and data workflow.
OSC spurs data reuse and helps address the issues related to data sharing and the reproducibility of published research results. Making OSC available to the research community has an impact on multiple disciples where data integrity and capturing detailed provenance are of importance.
