Asynchronous Flow invocations with Corda Services

How can I make my Flows faster? There's a good chance you have thought about this before if you have been working with Corda for a while. You can make reasonable tweaks to eke out performance improvements by changing a few things: transaction size, optimising queries and reducing the number of network hops required throughout ...

Containerising a Spring Data Cassandra application

I'm continuing my journey of learning Docker. I am still keeping it simple at this point. This time around, I am going to tackle converting a Spring and Cassandra application to use containers instead of running locally on the host machine.

This time, rather than focusing on Corda, we'll look at using Spring with Corda. More specifically, Spring WebFlux. Why do this? One, because we can. Two, because it ...

Developing with 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. ...

What is 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 Distributed Ledger ...
