@ -24,17 +24,6 @@ interface is defined as follows:
val participants: List<AbstractParty>
}
The first thing you'll probably notice about this interface declaration is that its not written in Java or another
common language. The core Corda platform, including the interface declaration above, is entirely written in Kotlin.
Learning some Kotlin will be very useful for understanding how Corda works internally, and usually only takes an
experienced Java developer a day or so to pick up. However, learning Kotlin isn't essential. Because Kotlin code
compiles down to JVM bytecode, CorDapps written in other JVM languages can interoperate with Corda.
If you do want to dive into Kotlin, there's an official
`getting started guide <https://kotlinlang.org/docs/tutorials/>`_, and a series of
`Kotlin Koans <https://kotlinlang.org/docs/tutorials/koans.html>`_.
We can see that the ``ContractState`` interface has a single field, ``participants``. ``participants`` is a list of the
entities for which this state is relevant.
