I have a network with 5 nodes, where node 1 is Company ABC and node 2 to node 5 are customer1, customer2 , customer3 etc. If customer1 uses Company ABC's product and if he gets a profit , he has to pay certain amount to Company ABC. The profit formula varies from customer to customer and customers should not see other customers profit formula. One customer can use the formula as A * B , where another customer can use as A+B*10 I referred the link: When deploying Corda nodes across the network, which JARs have to be exactly the same? My doubts. In my scenario , where should I write the formula

Closed . This question needs to be more focused . It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post . Closed 2 years ago . How do we implement schedulable state in corda? In my case i need to issue a monthly statement, so can schedulablestate be used for this? There are a number of things you need to do. Firstly, your state object needs to implement the SchedulableState interface. It adds an additional method: interface SchedulableState : ContractState { /** * Indicate whether there is some activity

I am trying to implement the following use-case in Corda: FlowA has been invoked on PartyA via startFlowDynamic . FlowA creates a partially signed transaction and invokes FlowB on PartyB via sendAndReceive . A human user shall now review and manually approve this transaction. Ideally FlowB should suspend after receiving the transaction. I would like to be able to query for suspended instances of FlowB via RPC, and present those (or rather some representation of the transaction therein) to the user in my UI. Then, after the user actions his approval, I would like to resume FlowB via RPC, which

I am getting the following issue when I perform the gradle clean deployNodes command on AWS Ubuntu machine for Corda project: Error while generating node info files I am using Corda ENT libs. And interestingly the same corda project works on the Windows machine but fails on AWS machine. JDK 1.8.181 and gradle 4.10.2 on AWS and windows machine. It asks to check logs files but logs show nothing related to any error ... Can you please help with this issue? It's giving an exception for: if (!process.waitFor(3, TimeUnit.MINUTES)) { process.destroyForcibly() throw IllegalStateException("Error while

I want to add the security property to my node configuration using Gradle. I'm trying to do something like the below: node { name "O=Bank_A,L=New York,C=US" p2pPort 10005 rpcSettings { address("localhost:10006") adminAddress("localhost:10046") } h2Port 9005 cordapps = [ "$project.group:bank-abc:$project.version", "$project.group:shared-contracts-states:$project.version", "$corda_release_group:corda-finance:$corda_release_version" ] security = { authService = { dataSource = { type = "DB" passwordEncryption = "SHIRO_1_CRYPT" connection = { jdbcUrl = "jdbc:h2:tcp://10.0.75.1:9014/node" username =

In Corda, I want to create several different versions of a responder flow, each to be used by a different node. To do so, I understand that I need to define each responder flow in a separate CorDapp. However, they also all need to depend on the initiating flow class via the InitiatedBy annotation. How can I structure the CorDapps containing the different implementations of the responder flow so that they all depend on this common initiating flow, without including all the responder flows in the same CorDapp where I defined the initiating flow? Well, the question comes that, Why owner of
