Initial conversion of Explorer to use IssuerFlow (from BankOfCorda) Initial conversion of TraderDemo to use IssuerFlow (from BankOfCorda) Updated TraderDemo to use IssuerFlow (from BankOfCorda) Fixed TraderDemo integration text (added new BankOfCorda node) Updated Explorer with changes IssuerRequest params Explorer now correctly displaying transaction id upon Issue. Moved IssuerFlow into finance package so can be reused across multiple demos (TraderDemo) and applications (eg Explorer) Refactored BankOfCorda demo to use Finance package and TestUtil constants Updated TraderDemo to use IssuerFlow Updated Explorer to use finance package IssuerFlow. Advertised BankOfCorda as Issuer for usage by Explorer. Explorer no longer depends on BankOfCorda demo since IssuerFlow promoted to Finance module Added IssuerFlow to AbstractNode whitelist. Explicit declarations of IssuerFlow no longer required. Added plugin registration of IssuerFlow at bootstrap. Revert whitelisting of IssuerFlow (plugin configured) Refactored to use constant BOC definition. Added gradle RPC security config. Updated documentation Fixed incorrect references. Renamed Issuer banks. Added new permission set (for Issuer nodes) Added node nearestCity info Added new Issuer Event Generator for Issuer nodes only Associated currency with issuer using ServiceType naming structure. Added argument flag (-S) to trigger event generator simulation node. Fixed problem with issuers not resolving from network map. Updated perms on Issuer rpc proxy nodes. Fixed minor in cash generateExit identified by Explorer. Changes applied in prep for AWG demo. Added IntelliJ run-configurations for launching Explorer demo nodes (with and without simulation) Updated documentation (and added additional gradle task to launch Explorer nodes in simulation mode). Fix following rebase. Addressed review items from PR. Updated TraderDemo readme. Updated TraderDemo gradle file to launch Bank of Corda node. Updated JRE properties. Updated IssuerModel to incorporate correct JFX Observable handling. Fixed bug with Exit command not displaying any currency. Added TODO's for revisiting correct Exception handling strategy. Optimization for when issuing cash to self. Minor updates following PR review. Remove old refs to Royal Mint and Federal Reserve
Corda
Corda is a decentralised database system in which nodes trust each other as little as possible.
Features
- A P2P network of nodes
- Smart contracts
- Flow framework
- "Notary" infrastructure to validate uniqueness of transactions
- Written as a platform for distributed apps called CorDapps
- Written in Kotlin, targeting the JVM
Read our full and planned feature list here.
Getting started
Firstly, read the Getting started documentation.
Watching the following webinars will give you a great introduction to Corda:
Webinar 1 – Introduction to Corda
Richard Brown, R3 Chief Technology Officer, explains Corda's unique architecture, the only distributed ledger platform designed by and for the financial industry's unique requirements. You may want to read the Corda non-technical whitepaper as pre-reading for this session.
Webinar 2 – Corda Developers’ Tutorial
Roger Willis, R3 Developer Relations Lead, provides an overview of Corda from a developer’s perspective and guidance on how to start building CorDapps. You may want to view Webinar 1 - Introduction to Corda as preparation for this session. NB. This was recorded for the M5 release.
Building on Corda
To build your own CorDapps:
- Clone the CorDapp Template repository
- Read the README (IMPORTANT!)
- Read the Writing a CorDapp documentation
To look at the Corda source and run some sample applications:
- Clone this repository
- To run some sample CorDapps, read the running the demos documentation
- Start hacking and contribute!

Development State
Corda is currently in very early development and should not be used in production systems. Breaking changes will happen on minor versions until 1.0. Experimentation with Corda is recommended.
Pull requests, experiments, and contributions are encouraged and welcomed.
Background
The project is supported by R3, a financial industry consortium, which is why it contains some code for financial use cases and why the documentation focuses on finance. The goal is to use it to construct a global ledger, simplifying finance and reducing the overheads of banking. But it is run as an open source project and the basic technology of a peer-to-peer decentralised database may be useful for many different projects.
