Special Interest Groups

Name	Description
Climate Action and Accounting SIG Home	The Climate Action and Accounting Special Interest Group (CA2SIG) is focused on supporting the development of an open global climate accounting system to support stakeholders' efforts to manage our single planetary carbon budget and help achieve the goals of the Paris Agreement (the United Nation's global climate accord). To accomplish this, the CA2 SIG is fostering a collaborative network of stakeholders to explore how to use digital technologies such as blockchain DLT, open source software, AI, IOT, Big Data, machine learning, etc. to create a transparent climate accounting system that is capable of balancing global climate emissions against global climate actions in order to achieve a net-zero carbon future.
Financial Markets SIG	The Financial Markets Special Interest Group (FMSIG) represents industry professionals working together to study how Hyperledger DLTs interact with Financial Markets use cases. These use cases cover issuance and trading of traditional and digital instruments to continued market-making, liquidity, short-term funding management of risk, program-trading, regulations, capital requirements, traceability, post trade settlement, custody including corporate actions and more. This group also explores architecture, standards, regulations, identity and performance related considerations specific to Financial Markets and DLTs.
Healthcare SIG	The Healthcare SIG represents healthcare professionals and technologists, and globally unites in advancing the state of the healthcare industry through the implementation of technology solutions using blockchain technologies in general, and the umbrella of Hyperledger frameworks and toolsets in specific.
Identity Special Interest Group	The purpose of the Identity Special Interest Group is to discuss, research, and document ways to capture, store, transmit and use Identities on the DLT, specifically for the projects in the Hyperledger greenhouse. The Identities can be of nodes that participate in the running of the DLT or entities that transact on the DLT.
Media and Entertainment SIG	The Media and Entertainment Special Interest Group (MESIG) brings together technical, academic, and industry-related expertise in an effort to exploit new blockchain and DLT technologies with a view to solving long-standing problems in the creation, fair distribution, and legally appropriate attribution of media assets.
Public Sector SIG	Hyperledger Public Sector Special Interest Group (public-sector-SIG) is a Special Interest group focused on applying distributed ledger technology in general, and Hyperledger technologies in particular, to the public sector (e.g., government and government-related) uses and needs.
Supply Chain and Trade Finance SIG Home	Hyperledger Supply Chain and Trade Finance Special Interest Group (ST-SIG) represents a global membership of Logistics, Supply Chain and Trade Finance professionals united in advancing the state of the supply chain industry through the implementation of enterprise-grade technology solutions utilizing the Hyperledger greenhouse of business blockchain frameworks and tools.
Telecom SIG	The Hyperledger Telecom Special Interest Group is focused on technical and business-level conversations about appropriate use cases for blockchain technology in the Telecom industry.
