Hi Igor, 

Corda 5 has not enabled the attachment functionalities yet. But it is on the roadmap for features. We will most likely send out a newsletter when new features are added to Corda 5. 

Please stay tuned.

Hi Munera, 

Corda 5 has token capabilities by default. The TokenSDK is built into the core of Corda 5. You dont need to add the SDK anymore.

Hi Ryan, 

This seem like an open-ended question. You can of course build an IOS app on top of your corda solution. Corda is backend distributed ledger platform where it stores data decentralizely, conbatting the distrust that happen when data at rest. 

You can choose to develope it on our legendary Corda 4 or the newly released Corda 5. On Corda 4, you do need to implement a REST client to connect Corda and your app. Whereas on Corda 5, the Corda flow triggering are exposed via swagger APIs, so you can directly connect Corda with your IOS app. 

More info can be found at here. Happy developing!

Here’s a quick generated js client in React we put together. https://github.com/amoothart/currency-mbs-ui/tree/master/src/services
This code works but is only suitable for demos/PoCs because it is polling the Corda cluster.

I think you slightly misunderstood the concept of Corda 5. Corda 5 has vNodes that can be run on the same cluster (e.g. provided by a SaaS provider) – but that is not required.

A Corda 5 network can span many clusters run by different operators, and there is nothing stopping participants running their own clusters and owning the full stack.

Hi Philip,

We had identified the bug and will work on it. We had opened the ticket [CORE-15098] to document this bug.

Hi Kiran,

You can download all the files you need to build a Corda 5 environment at the above link.

The Contract testing API and flow testing API will be released soon.

Hi both, 

The latest version of the Corda 5 beta is Iguana (this is the 4th version of the beta). download link is here: https://developer.r3.com/next-gen-corda/ 

With Iguana, you would need both digicert-ca.pem and gradle-plugin-default-key.pem to sign the CPI. This includes the mgm cpi, the notary cpi, and the App cpi.

Corda 5 will be available in 2023 Summer. We had already published a public release of our beta 4 release of the Corda 5 software.

The CSDE currently spins up a clean network each time Corda is started. We haven’t investigated making the set up/ data persist.

However, you can reupload the Cordapp code on hot (via csde), meaning you can redeploy the cordapp while the cluster running, which I don’t think you could do in corda 4.

So whilst developing against the corda cluster, you would just leave your cluster up and running.

That is, we dont’ nuke the cluster on each forced upload, but we do if you stop the cluster and restart.

The reason is quite simple. It is to avoids duplication of code, which is easier to debug.  And more that there’s no need to write it twice as the responder logic is identical in both.

That is, for flows that share the similar responder logic, they all should try to have the finalization code in a seperate file and keep re-use it.

Here is what happen if the transaction proposer does not add his/her own signature via the addSignatories() function:

You will get an error saying: The publickeys do not have any private counterparts available
