Hyperledger’s Community Groups are a way for technical and non-technical people to get involved with the community. All groups are open forums and you are invited to participate in any of the groups that look interesting to you. All are welcome!



The HLHC’s mission is to house and foster technical and business-level conversations about appropriate applications for blockchain technology in the healthcare industry. These conversations will initially be broad and educational, but will transition to focus on identifying opportunities for near-term collaboration between participants on common software to implement a given application. If appropriately scoped and resourced, these conversations will lead to one or more proposals for new software development efforts to be hosted at Hyperledger.

Get Involved

An Identity is a dynamic collection of sets of attributes attached to an entity. In order to accrete trust and be useful for authorization, these attributes must be verifiably attested by other entities. It is a primary building block for Distributed Ledger Technology (DLT). The purpose of the Identity Working Group is to discuss, research, and document ways to capture, store, transmit and use Identities on the DLT, specifically for the projects under the Hyperledger umbrella.
