* Check array size before accessing * Review fixes * CORDA-540: Make Verifier work in AMQP mode (#1870) * reference to finance module via not hardcoded group ID (#1515) * generic way to reference to group id when loading finance.jar via cordapp * Fixed the node shell to work with the DataFeed class * Attempt to make NodeStatePersistenceTests more stable (#1895) By ensuring that the nodes are properly started and aware of each other before firing any flows through them. Also minor refactoring. * Disable unstable test on Windows (#1899) * CORDA-530 Don't soft-lock non-fungible states (#1794) * Don't run unlock query if nothing was locked * Constructors should not have side-effects * [CORDA-442] let Driver run without network map (#1890) * [CORDA-442] let Driver run without network map - Nodes started by driver run without a networkMapNode. - Driver does not take a networkMapStartStrategy anymore - a new parameter in the configuration "noNetworkMapServiceMode" allows for a node not to be a networkMapNode nor to connect to one. - Driver now waits for each node to write its own NodeInfo file to disk and then copies it into each other node. - When driver starts a node N, it waits for every node to be have N nodes in their network map. Note: the code to copy around the NodeInfo files was already in DemoBench, the NodeInfoFilesCopier class was just moved from DemoBench into core (I'm very open to core not being the best place, please advise) * Added missing cordappPackage dependencies. (#1894) * Eliminate circular dependency of NodeSchedulerService on ServiceHub. (#1891) * Update customSchemas documentation. (#1902) * [CORDA-694] Commands visibility for Oracles (without sacrificing privacy) (#1835) new checkCommandVisibility feature for Oracles * CORDA-599 PersistentNetworkMapCache no longer circularly depends on SH (#1652) * CORDA-725 - Change AMQP identifier to officially assigned value This does change our header format so pre-cached test files need regenerating * CORDA-725 - update changelog * CORDA-680 Update cordapp packages documentation (#1901) * Introduce MockNetworkParameters * Cordformation in Kotlin (#1873) Cordformation rewritten in kotlin. * Kotlin migration * Review Comments * CORDA-704: Implement `@DoNotImplement` annotation (#1903) * Enhance the API Scanner plugin to monitor class annotations. * Implement @DoNotImplement annotation, and apply it. * Update API definition. * Update API change detection to handle @DoNotImplement. * Document the `@DoNotImplement` annotation. * Experimental support for PostgreSQL (#1525) * Cash selection refactoring such that 3d party DB providers are only required to implement Coin Selection SQL logic. * Re-added debug logging statement. * Updated to include PR review feedback from VK * Refactoring following rebase from master. * Fix broken JUnits following rebase. * Use JDBC ResultSet getBlob() and added custom serializer to address concern raised by tomtau in PR. * Fix failing JUnits. * Experimental support for PostgreSQL: CashSelection done using window functions * Moved postgresql version information into corda/build.gradle * Using a PreparedStatement in CashSelectionPostgreSQLImpl * Changed the PostgreSQL Cash Selection implementation to use the new refactored AbstractCashSelection * * Retire MockServiceHubInternal (#1909) * Introduce rigorousMock * Add test-utils and node-driver to generated documentation * Fix-up: Bank Of Corda sample (#1912) In the previous version when running with `--role ISSUER` the application failed to start. The reason was that in spite of `quantity` and `currency` were optional, un-necessary `requestParams` been constructed regardless. * move SMM * Interface changes for multi-threading * CORDA-351: added dependency check plugin to gradle build script (#1911) * CORDA-351: added dependency check plugin to gradle build script * CORDA-351: Added suppression stub file with example * CORDA-351: added suppresionFile property * CORDA-435 - Ensure Kryo only tests use Kryo serializatin context Also correct lambda typos (from lamba) * Network map service REST API wrapper (#1907) * Network map client - WIP * Java doc and doc for doc site * remove javax.ws dependency * NetworkParameter -> NetworkParameters * move network map client to node * Fix jetty test dependencies * NetworkParameter -> NetworkParameters * Address PR issues * Address PR issues and unit test fix * Address PR issues * Fixing Bank-Of-Corda Demo in `master` (#1922) * Fix-up: Bank Of Corda sample Use correct CorDapp packages to scan (cherry picked from commit |

Corda Enterprise
Corda Enterprise is R3's closed source patch set on top of Corda Open Source. It adds features and improvements that we plan to charge for.
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
Extra features
- Doorman
- SOCKS relaying
- Flow triage screen in Explorer
- No stupid jokes at startup
- SGX
Getting started
- Read the Getting Started documentation
- Run the Example CorDapp
- Read about Corda's Key Concepts
- Follow the Hello, World! tutorial
