  Configuring, managing and deploying a Corda network consists of a number of steps. To make this process easier and more efficient, the R3 team has built an in-house command-line tool for managing the entire life cycle of a Corda network, right from its creation to its termination. After using this tool for a good ...

Before starting Corda5 CorDapp development, perform the below steps to set up your development environment: Step 1 – Setup Java 11 and Gradle version 6 We want to be compliant with the current industry standard and hence Corda 5 is built and tested on Java 11. Corda 5 is not backwards compatible with any older ...

States, Contract, and Flows in Corda 5 In this blog, we will see how to write a State, Contract and Flow in Corda 5. States States in Corda 5 are similar to those in Corda 4 with subtle differences. In addition to your state implementing ContractState, you should also implement it against the JsonRepresentable interface. ...

The next major release of Corda (v5) will mark a major milestone in the evolution of Corda. The GA release of Corda 5 will be preceded by multiple Developer Preview releases, including different features of Corda 5 to allow developers to have a taste of the brand new version of Corda. It also provides an ...

One common piece of feedback we got from CorDapp developers was about the RPC API used to communicate with the Corda node. They asked: why don’t we use the HTTP API to ease things and allow developers to communicate with the Corda node with a simple HTTP client rather than having to build a client ...

We have released Corda 5 Developer Preview I (Corda 5 DP1) with the primary aim of hearing our Corda developers’ thoughts and feedback early, so we can adjust our directions and priorities based on that. One of the main focuses of Corda 5 DP1 is new modular APIs, which means all APIs are in separate ...

In the Venture Development team, we regularly get founders who want to build blockchain applications and we get why! The advantages of decentralisation, immutability and security are hard to resist. However, many times CorDapp builders forget it’s important to build a solution that needs the advantages of blockchain, especially a permissioned-private ledger like Corda. Additionally, ...

Electronic voting has been making headlines. Would it be possible to one day run secure elections using blockchain and other distributed ledger technologies? Let’s have a look at how you could implement an Electronic Voting Machine (EVM) system using Corda. Then, we can play with some sample code. The example architecture consists of a series ...

What is Flow? Flow is a place where you put your business logic. You can think of it as the main function in C++ or Java, but you start it via RPC (hence you have @StartableByRPC annotation for your flow). Why we need Flows? Since we are on the network, you can communicate or transact ...
