OpenGovChain is an open source blockchain.

Open SourceFree to Use

A base blockchain platform for government transparency, designed to be extended with tokenomics, governance, and additional utilities as needed.

OpenGovChain is a decentralized blockchain network designed to store and manage government datasets with complete transparency. Built as a foundational platform, agencies can extend it with custom modules for tokenomics, governance, financial transactions, and other blockchain utilities based on their specific needs.

100% Open Source & Free for All Agencies

OpenGovChain is completely free and open source. Any government agency, organization, or individual can use, modify, and deploy this platform without restrictions or licensing fees.

Project in Active Development

OpenGovChain is currently under active development. Technical specifications, features, and implementation details may change as we refine the platform based on community feedback and real-world testing.

We Need Your Help!

We're looking for volunteers to help build, test, and improve OpenGovChain. Whether you're a developer, designer, government official, or transparency advocate, your contribution can make a difference.
