Corda is an open source blockchain project, designed for business from the start. Only Corda allows you to build interoperable blockchain networks that transact in strict privacy. Corda's smart contract technology allows businesses to transact directly, with value.

* CORDA-1393: Install `onError()` handler for folding action or else `ErrorNotImplementedAction` will be invoked which is never a good thing * CORDA-1335: Improve exception handling in `cleanUpOnConnectionLoss()` * CORDA-1335: Try to trick the logic to pretend we are running in HA mode to have a chance of re-connecting. * CORDA-1416: Make `NodeMonitorModel` code react to proxy changing. * CORDA-1416: Workaround `CordaRPCOps.equals()` calls when listener dispatching change. * CORDA-1416: Increase re-try interval to allow enough time for server to come back online. * CORDA-1355: Properly close RPC connection we are moving away from. * CORDA-1355: Unsubscribe on Error to prevent propagation of it downstream. * CORDA-1355: For downstream subscribers ignore errors properly. Thanka to @exfalso for the hint. This fixes: Transaction Updates do not flow after re-connect * CORDA-1355: Bugfix eliminate duplicating items on "Transactions" blotter after re-connect. * CORDA-1355: Bugfix eliminate double counting on dashboards. * CORDA-1355: Bugfix eliminate same parties in dropdowns. * CORDA-1355: Stop using `SecureHash.randomSHA256()` for painting widget icon. Instead use combined SHA hash such that icon represents the whole population of trades. That way two transactions blotters can be compared by a single glimpse at corresponding icons. Also minor refactoring. * CORDA-1416: Make RPC re-connection faster/more robust. * CORDA-1416: Properly announce thet Proxy may not be available during re-connect and prevent UI crashing. * CORDA-1416: Disable UI until RPC proxy is available. * CORDA-1416: Correct typo. * CORDA-1416: Unit test fix. * CORDA-1416: GUI cosmetic changes. * CORDA-1416: Correct spaces. * CORDA-1416: Remove un-necessary overrides in CordaRPCOpsWrapper. * CORDA-1416: Switch from using `doOnError` to installing an error handler upon subscription. |

Corda
Corda is a decentralised database system in which nodes trust each other as little as possible.
Features
- Smart contracts that can be written in Java and other JVM languages
- Flow framework to manage communication and negotiation between participants
- Peer-to-peer network of nodes
- "Notary" infrastructure to validate uniqueness and sequencing of transactions without global broadcast
- Enables the development and deployment of distributed apps called CorDapps
- Written in Kotlin, targeting the JVM
Getting started
- Read the Getting Started documentation
- Run the Example CorDapp
- Read about Corda's Key Concepts
- Follow the Hello, World! tutorial
