What's included?
|
|
================
|
|
|
|
The Corda prototype currently includes:
|
|
|
|
* A peer to peer network with message persistence and delivery retries.
|
|
* Key data structures for defining contracts and states.
|
|
* Smart contracts, which you can find in the :doc:`contract-catalogue`.
|
|
* Algorithms that work with them, such as serialising, hashing, signing, and verification of the signatures.
|
|
* API documentation and tutorials (what you're reading).
|
|
* A business process orchestration framework.
|
|
* Notary infrastructure for precise timestamping, and elimination of double spending without a blockchain.
|
|
* A simple REST API, and a web app demo that uses it to present a frontend for IRS trading.
|
|
|
|
Some things it does not currently include but should gain later are:
|
|
|
|
* Sandboxing, distribution or publication of smart contract code
|
|
* A user interface for administration
|
|
|
|
The prototype's goal is rapid exploration of ideas. Therefore in places it takes shortcuts that a production system
|
|
would not in order to boost productivity:
|
|
|
|
* It uses an object graph serialization framework instead of a well specified, vendor neutral protocol.
|
|
* There's currently no permissioning framework.
|
|
* Some privacy techniques aren't implemented yet.
|
|
* It uses an embedded SQL database and doesn't yet have connectivity support for mainstream SQL vendors (Oracle,
|
|
Postgres, MySQL, SQL Server etc).

Kotlin
|
|
------
|
|
|
|
Corda is written in a language called `Kotlin <https://kotlinlang.org/>`_. Kotlin is a language that targets the JVM
|
|
and can be thought of as a simpler Scala, with much better Java interop. It is developed by and has commercial support
|
|
from JetBrains, the makers of the IntelliJ IDE and other popular developer tools.
|
|
|
|
As Kotlin is very new, without a doubt you have not encountered it before. Don't worry: it is designed as a better
|
|
Java for industrial use and as such, the syntax was carefully designed to be readable even to people who don't know
|
|
the language, after only a few minutes of introduction.
|
|
|
|
Due to the seamless Java interop the use of Kotlin to extend the platform is *not* required and the tutorial shows how
|
|
to write contracts in both Kotlin and Java. You can `read more about why Kotlin is a potentially strong successor to Java here <https://medium.com/@octskyward/why-kotlin-is-my-next-programming-language-c25c001e26e3>`_. |
