A distributed ledger with a difference.

Corda is an open-source distributed ledger platform designed to record, manage and automate legal agreements between businesses. It offers a unique response to the privacy and scalability challenges facing decentralised applications.

Corda's development is led by R3, a fintech company that heads a consortium of over 70 of the world's largest financial institutions in the establishment of an open, enterprise-grade, shared platform to record financial events and execute smart contract logic.

Corda is now supported by a growing open-source community of professional developers, architects and hobbyists. Check out our forum and Slack to get involved.

What makes Corda different?

Engineered for business

Corda is the only distributed ledger platform designed by the world’s largest financial institutions to manage legal agreements on an automatable and enforceable basis

Restricted data sharing

Corda only shares data with those with a need to view or validate it; there is no global broadcasting of data across the network

Pluggable consensus

Corda is the only distributed ledger platform to support multiple consensus providers employing different algorithms on the same network, enabling compliance with local regulations

Easy integration

Corda is designed to make integration and interoperability easy: query the ledger with SQL, join to external databases, perform bulk imports, and code contracts in a range of modern, standard languages

You can also start developing your own CorDapps (Corda Distributed Applications) using the CorDapp Template repo.

The Corda repo on Github contains Corda's open-source code, as well as a number of useful samples to help get familiar with Corda development.

If you're just looking to get a feel for Corda in action, you can quickly spin up some demo Corda networks using a Microsoft Azure virtual machine.
