The Emergence of Enterprise Tokens Can we have our (Corda) cake and eat it too? Unspent Corda Cake Output Could the same enterprise-ready focus that lead to the design and capabilities of Corda also extend to the ‘wild west’ of the token world? In others words: we may be on the cusp of the emergence of ...

Intro to SGX: from HTTP to enclaves I recently submitted a design for the SGX infrastructure we are building at R3, and another design for the integration of SGX into Corda. Although the primary use case is Corda, we are trying to build an agnostic SGX-in-the-cloud infrastructure. In this blog post, I’d like to give an ...

DJVM Behind the Scenes Yesterday I posted some details about our work on a deterministic sandbox for the JVM to ensure deterministic execution of contract code for Corda. The module is currently being reviewed and is not yet integrated with the platform, but I thought I would follow up and shed some more light on what ...

Deterministic Contract Verification Update: I have posted another article that dives into the details of the DJVM . This video demonstrates the djvm command line tool that comes with DJVM. The tool can be used to check validation steps and explore transformations made by the deterministic sandbox. It enables the user to quickly build new runnable ...

Daniel Newton in Corda I’ve recently started a project (top secret, can’t say anymore) which involves using Corda. So, what is it? If you’ve found this post on Google then you probably already have some sort of idea, but if you’ve come from most other sources then it most likely doesn’t sound familiar. Well, Corda is a ...

Daniel Newton in Corda In my last post I gave an overview of what Corda is trying to achieve and the design decisions that were made to do so. That information is great to know so we can get some perspective of the platform but it’s not going to help us in writing a system that can leverage Corda. ...

The Return of the DAO A New Hope Until now, most organisations have written their own computer systems and have each kept their own copies of data. This leads to trouble with reconciliation, as well as systemic issues, given each institution will have slightly different code. Distributed ledger technology (DLT) allows institutions to share both data ...

Richard Brown in Corda I’m delighted to announce the formation of the Corda Technical Advisory Council (the Corda TAC). This is a group of technical leaders in our community — who most of you know well — who have volunteered to commit their time over and above their existing contributions to the Corda ecosystem to provide advice ...

Test Driven Development for Blockchain Apps with R3 Corda — How to Write Contracts and Unit Tests Please note that I am not affiliated with R3. This tutorial will explain and provide examples for how to write unit tests for Contracts in Corda using Java and IntelliJ. Testing for decentralized applications is especially critical because without the centralized ...

Corda: Open Source Community Update The Corda open source community is getting big… it’s time for a dedicated corda-dev mailing list, a co-maintainer for the project, a refreshed whitepaper, expanded contribution guidelines, and more..! It feels like Corda took on board some rocket fuel over the last few months. Corda’s open source community is now ...
