This requires Kotlin 1.2 versions of core and serialization (core-1.2 and serialization-1.2 respectively), which are just "shell" modules and which compile the existing source code with Kotlin 1.2. The 1.2 plugin does not work with the current version of Gradle and so the 1.2 compiler has to be called directly. Now with two versions of Kotlin in the code base, each module needs to have its version manually specified to ensure a clean separation. Otherwise, the default Kotlin version can override 1.2 when needed. Some of the code was tidied-up or improved to enable it to be cross-compiled. For post-1.2 APIs being used, they have been copied into core-1.2 with the same method signatures. OpenTelemetryComponent was moved to node-api, along with the dependency, to avoid also having a 1.2 version for the opentelemetry module. |

Corda
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.
Architecture Evolution
The code present in this repository reflects the first version of the implementation of the Corda model for DLT technology. This first architecture version covers Corda versions 1 through 4 and continues to deliver on the promise of DLT for both the open source community and industry as a whole.
However, like all things, Corda must evolve to serve the more stringent needs of today. This is why the second (and current) version of the Corda Architecture can be found here and will form the basis of the Corda 5 release.
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
