* Updated all sample code to use new Vault Query service APIs. * Fix broken Unit test. * Added missing transaction boundary. * Fix broken ScheduledFlow test (caused by assertion on non-ordered collection) * Remove redundant negative test (as new Vault Query no longer returns iterators). * Whitespace formatting fixed following PR review from SA. * Force query to specify a PAGE SIZE equivalent to total states to be exited (RP review comment). * Use single (and fail fast) instead of first - when only expecting a single result. * Demonstrate paging and sorting; failfast on single expected result. * Enhancement: added Sorting by CommonStateAttribute (StateRef txnId and index) * Fix: incorrect total states count. * Fixed incorrect total states counting. * Remove redundant filter (UNCONSUMED). * Updated tutorial code and associated documentation (building transactions). * Updated all vaultAndUpdates to vault[Track|Query]By. * Temporary disable failing Vault Query tests (awaiting pagination PR fix). * Rebase from master to pick up pagination changes/fix. * Fixed criteria filter on track. * Cleanup redundant print output. * Refactor to extract common function for Vault Query paging and sorting. * Identified problem in SimmValuation demo failing test caused by query by single participant in participants list (not yet supported in VaultQuery criteria). * Minor fixes following rebase from master. * Minor updates following rebase. * Removed redundant import. * Fixed type casting error. * Minor fixes following rebase from master. * VQ Fix - applied in other PR. * Removed duplication after rebase and minor fix to failing smoke test. |

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 developer’s 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:
- Clone the CorDapp Template repository
- Read the README (IMPORTANT!)
- Read the Writing a CorDapp documentation
To look at the Corda source and run some sample applications:
- Clone this repository
- To run some sample CorDapps, read the running the demos documentation
- 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.
