Facilitating the future reuse of data is critical to the advancement of research. Researchers need the ability to independently validate the authenticity of scientific datasets and track the provenance information to extend or build upon prior research. The National Science Foundation funded Open Science Chain project is building a cyberinfrastructure solution to enable a broad set of researchers to efficiently verify and validate the authenticity of scientific datasets and share metadata including detailed provenance information in a secure manner. In this demonstration, we will show how science gateway users can benefit from utilizing the Open Science Chain cyberinfrastructure to indicate the trustworthiness of their data.
