Protocol -> Flow renaming Bank of Corda demo - Issuer of Cash Resolve BankOfCorda through NMS in protocol Fixes following Integration testing. Protocol -> Flow renaming Addressed all comments in PR review. Removed bank lines. Updated minor inconsistency in README.md All protocol references changed to flow. changed protocol -> flow in TODO comment. changed startProtocolPermission -> startFlowPermission in README.md Added transaction id to IssuerFlow Success response. Removed explicit call to record Cash Move transaction (as already recorded in subflow) Removed quasar dependency. Addressed comment in PR. Updated to use CompositeKey. Added arguments to pass in Currency and Amount. Updated run configurations to pass in Currency and Amount values Added additional parameter to IssuerFlow request: issueToPartyReference Added Vault updates verification in RPC Integration test. Fixed RPC Integration test (Vault assertions) Updated run-time dependencies in line with other demos. Applied changes following PR review (exception handling, party resolution handling, docs) Updated gradle client run configs with new parameters. Main driver app now uses standard out for display (was using logger info() but nothing was being displayed because of restrictive config) Fixed formatting display problems. Updated Web Api code to use new CordaRPCOps interface (and new partyFromName() exposed method) Removed unused import.
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

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.
