Imagine a firm needs a new way for employees to book vacation. Or maybe customers want to be able to track their orders online. It’s your job to build the application. What design would you go with? Chances are you’ll build it in much the same way as everybody else does. There will be a database. There will be a business logic layer – you have a lot of choices here. And there will be a front-end – perhaps a mobile app or web-site, or a set of APIs. And then you have to worry about hosting it. Perhaps the HR department will host it in-house. Perhaps the supplier will host it in the cloud.

In this blog post we will show how to build and deploy a simple example of a Corda Distributed Application (CorDapp) for Corda 5 using a snapshot of Corda 5 from when it was first open sourced around mid May 2022. This CorDapp will run a workflow, AKA a “flow”, that calculates the sum of ...

Corda 5 was designed from the outset to be cloud-native. Specifically, the worker architecture allows for independent scaling and resilience of the components that make up the Corda platform, all loosely coupled via a message bus. The usage of container images as the delivery mechanism for those components and Kubernetes as the runtime orchestrator should be fairly uncontroversial. This article discusses the rationale for the decision to use Helm to package the Kubernetes configuration.

We are really excited to present to you today the first preview of the new peer-to-peer communications layer of Corda 5, which is now open source. If you are not familiar with what Corda 5 aspires to deliver, we highly recommend reading the previous “Corda 5 the road ahead” blog post series from R3’s product management team. This preview is a good indication of how Corda 5 delivers on the areas of multi-tenancy, horizontal scalability and high availability.

The code for the latest version of the world’s most successful enterprise blockchain platform is now open source. Is it finished and ready to use? No. Is it close? Getting there – watch this space. Is it cool? It is very cool. I’m here to explain what the team at R3 have made available, where to find it, and why we’re doing this now.

Performance is an important aspect of any enterprise software application. Blockchain is seen as the next big thing that could change the way we transact in the near future. However, blockchains are slow. This is one of the major reasons why businesses are skeptical about using a blockchain-based system in a major way.

The world is rapidly changing as we continue to come out with new and innovative ways to do things faster, more efficiently, and more cost-effectively. However, banking is still lagging behind—hardly much has changed, and we still take days and weeks to process financial transactions. Modern banking is still inefficient and costly. Why is this and what can be done about it?

The use of distributed ledger technology (DLT) to establish digital trust is increasing rapidly across myriad sectors. R3’s Corda is the industry-standard platform for developers who build DLT applications for highly regulated markets, including banking, trade finance and capital markets. No matter where you are on your blockchain application development journey or which version of Corda you are using, R3 is here to support your build and shorten your time to deployment.

R3's customers in regulated industries require secure and highly available services that process data with integrity to maintain confidentiality and privacy. We currently support enterprise customers through our 24x7 customer support, blockchain application firewall, Hardware Security Module (HSM) integrations and compliance with industry-wide information security standards. 

By Dr. Iryna Tsimashenka R3 has launched the Technical Preview of Corda Payments, a new payment initiation and processing module for CorDapps. Corda Payments enables developers to quickly connect to traditional off-ledger payment rails and payment service providers with minimal coding. Corda Payments includes out-of-the-box integration with Modulr—a banking as a service provider for UK ...
