The Hyperledger Architecture Work Group (AWG) is a technical workgroup focused on developing an architectural framework for Enterprise class distributed ledgers, towards convergence on a modular architecture. This includes identifying common and critical components, providing a functional decomposition of an Enterprise blockchain stack into component layers and modules, regularizing interfaces between the components, and interoperability between ledgers.

The AWG serves as a cross-project forum for architects and technologists from the Hyperledger community to exchange ideas and explore alternate architectural options, discuss the tradeoffs, and capture the reasoning behind the choices. The AWG provides recommendations and architectural guidance to the projects under the Hyperledger greenhouse and encourages them towards convergence on a modular architecture. The AWG invites individual Hyperledger projects for architecture and design review to benefit from the expertise from the community as well as to shape the architectural direction of Hyperledger.

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.

The Learning Materials Development Working Group is focused on developing open source training material to educate people interested in expanding their knowledge of Hyperledger and its projects. The working group will consult with other Hyperledger working groups, team members, and the project maintainers to identify training needs and develop strategies and material to address those needs for both technical and non-technical audiences.

Performance and scalability are two key characteristics of any platform. In terms of most of the  Hyperledger projects, both will directly relate to end user satisfaction and ultimately adoption of a project. The purpose of the Performance and Scale Working Group (PSWG) is to discuss, research, and identify key metrics that relate to the performance and scalability of a blockchain and blockchain related technologies.

The Technical Working Group China is a bridge between the global Hyperledger community and the technical community in the greater China region. This includes growing the Hyperledger developer community in China by responding to new user questions, helping with first-level triage of community-reported bugs or other issues, helping demonstrate how to report bugs or file pull requests, and pointing developers towards the project roadmaps.

The Healthcare SIG'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.

The activities of the Public Sector SIG include identifying related use cases, current pilots, and proofs of concept; sharing stories of successes, failures, opportunities, and challenges; exploring cross-cutting concerns like security, privacy, and identity in government contexts; identifying existing or needed common critical software components that would serve the particular needs of the public sector; identifying conferences or other opportunities to connect face to face, as well as submit talks or present as a group at an event.

The Social Impact SIG is primarily focused on serving as a platform for exchanging ideas and exploration of ways to use blockchain technology in the context of social good. The Social Impact SIG will work with the other groups and technical teams, especially in the areas of implementation. The SIG will focus on convening a broad ecosystem, leveraging the skills, capabilities and perspectives of individuals from the developer community, the social and humanitarian space, enterprises, government and non-government entities, and beyond.
