This group gathers academics, students and researchers to discuss opportunities of leveraging Hyperledger for research. As an open collaboration we welcome Non-Profit Organizations, Government, Educational and Research Institutions and any Public Sector Representatives. To formalize such collaboration we have created an Associate Membership Tier. Unlike for private sector General and Premier Members, for Associate members, no membership fee structure is imposed on qualified public sector members; however, all members will be expected and required to participate in applicable ways through the contribution of human capital, intellectual property, and/or goodwill. Hyperledger expects Associate Members to contribute in form of research, code development, documentation, collaboration with Working Groups etc. We believe that the variety of cultures, experiences and backgrounds can help grow the Hyperledger ecosystem.
