The Corda repository comprises the following folders:

  • buildSrc contains necessary gradle plugins to build Corda
  • client contains libraries for connecting to a node, working with it remotely and binding server-side data to JavaFX UI
  • config contains logging configurations and the default node configuration file
  • cordform-common contains utilities related to building and running nodes
  • core containing the core Corda libraries such as crypto functions, types for Corda’s building blocks: states, contracts, transactions, attachments, etc. and some interfaces for nodes and protocols
  • docs contains the Corda docsite in restructured text format as well as the built docs in html. The docs can be accessed via /docs/index.html from the root of the repo
  • experimental contains platform improvements that are still in the experimental stage
  • finance defines a range of elementary contracts (and associated schemas) and protocols, such as abstract fungible assets, cash, obligation and commercial paper
  • gradle contains the gradle wrapper which you’ll use to execute gradle commands
  • gradle-plugins contains some additional plugins which we use to deploy Corda nodes
  • lib contains some dependencies
  • node contains the core code of the Corda node (eg: node driver, node services, messaging, persistence)
  • node-api contains data structures shared between the node and the client module, e.g. types sent via RPC
  • node-schemas contains entity classes used to represent relational database tables
  • samples contains all our Corda demos and code samples
  • test-utils contains some utilities for unit testing contracts ( the contracts testing DSL) and protocols (the mock network) implementation
  • tools contains the explorer which is a GUI front-end for Corda, and also the DemoBench which is a GUI tool that allows you to run Corda nodes locally for demonstrations
  • verifier allows out-of-node transaction verification, allowing verification to scale horizontally
  • webserver is a servlet container for CorDapps that export HTTP endpoints. This server is an RPC client of the node
