Katelyn Baker 4cbf31681b Initial work towards integrating the serializer with the carpenter
Unit tests that pull out the envelope from a deserialsed object (which
we have already serialised) then using the AMQP schema contained within
convert that to a carpenter schema and build an object

Currently testing only simple classes with a single type member

Squashed merge commits:
	* Fix for the type issue in the SerializerFactory

  	  Needs to pull in the actual Java types otherwise we use the Kotlin types
	  as the map keys which will never correspond to the java types that the
	  wrapper wraps around the primitive before doing a map lookup

	  Boolean just doesn't seem to work as pulling that in starts breaking
	  Kotlin and Character also seems broken. There is a fix for this also on
	  Rick's branch so pushing this in for now and can use his actual changes
	  when they're available on Master

	* Better tests

	* Add support for sub classes known to the JVM

	* Initial work towards integrating serializer with the carpenter

	  Unit tests that pull out the envelope from a deserialsed object (which
	  we have already serialized) then using the AMQP schema contained within
	  convert that to a carpenter schema and build an object

	  Currently testing only simple classes with a single type member

Corda

Corda

Corda is a decentralised database system in which nodes trust each other as little as possible.

Features

  • A P2P network of nodes
  • Smart contracts
  • Flow framework
  • "Notary" infrastructure to validate uniqueness of transactions
  • Written as a platform for distributed apps called CorDapps
  • Written in Kotlin, targeting the JVM

Getting started

Firstly, read the Getting started documentation.

Next, use the following guides to set up your dev environment:

  • If you are on Windows use this getting started guide which also explains through how to run the sample apps.

  • Alternatively if you are on Mac/Linux, watch this brief Webinar which walks through getting Corda, installing it, building it, running nodes and opening projects in IntelliJ.

After the above, watching the following webinars will give you a great introduction to Corda:

Webinar 1 Introduction to Corda

Richard Brown, R3 Chief Technology Officer, explains Corda's unique architecture, the only distributed ledger platform designed by and for the financial industry's unique requirements. You may want to read the Corda non-technical whitepaper as pre-reading for this session.

Webinar 2 Corda Developers Tutorial

Roger Willis, R3 Developer Relations Lead, provides an overview of Corda from a developers perspective and guidance on how to start building CorDapps. You may want to view Webinar 1 - Introduction to Corda as preparation for this session. NB. This was recorded for the M5 release.

Building on Corda

To build your own CorDapps:

  1. Clone the CorDapp Template repository
  2. Read the README (IMPORTANT!)
  3. Read the Writing a CorDapp documentation

To look at the Corda source and run some sample applications:

  1. Clone this repository
  2. To run some sample CorDapps, read the running the demos documentation
  3. Start hacking and contribute!

Development State

Corda is under active development and is maturing rapidly. We are targeting production-readiness in 2017. The API will continue to evolve throughout 2017; backwards compatibility not assured until version 1.0.

Pull requests, experiments, and contributions are encouraged and welcomed.

Background

The project is supported by R3, a financial industry consortium, which is why it contains some code for financial use cases and why the documentation focuses on finance. The goal is to use it to construct a global ledger, simplifying finance and reducing the overheads of banking. But it is run as an open source project and the basic technology of a peer-to-peer decentralised database may be useful for many different projects.
