corda

问题 I have a use case where I need to add a new node to an existing Corda network (let's say in existing Corda network 2 nodes are running currently (A, B node) and now need to add node C to this network. I went through following links as well but no luck: Adding new node to existing corda network Couldn't find network parameters file and compatibility zone wasn't configured/isn't reachable Deploy and run nodes dynamically in CORDA I tried the following approach: I Added A and B nodes

However, the Corda documentation recommends that you use the Gradle Test Runner to perform tests: link When I switch to using

问题 I am trying to handcraft a Node folder with following contents - Corda.jar (1.4), Node.conf, cordapp (Folder).

问题 1.I downloaded from "git clone https://github.com/corda/samples" 2.I open project from Intellij As the page(https://docs.corda.net/tutorial-cordapp.html#downloading-the-example-cordapp) shows 3.I selected "Run Example Cordapp - Kotlin",And start Debugging 4.I get some exception from Intellij console I access "web address",But it's doesn't work. I guess server not working. How can I solve this Exeption? [INFO] 14:02:57,980 [driver-pool-thread-0] network.NodeInfoFilesCopier. - Now watching:

问题 Can someone please give me an example for corporatePasswordStore that is mentioned here: https://docs.corda.net/node-administration.html?fbclid=IwAR0gRwe5BtcWO0NymZVyE7_yMfthu2xxnU832vZHdbuv17S-wPXgb7iVZSs#id2 I've been doing a lot of research in the last few days on how to hide the plain passwords from node.conf ; it's a new topic for me and this is what I came up with so far: Create a priv/pub key with gpg2 Create a password store with pass (using the key that I generated earlier). Store

问题 Summary I've adapted the basic Token Issuance Corda Bootcamp application to demonstrate this issue. I want to create a bidirectional mapping between TokenStates and TokenChildren where the relationship is one-to-many. What are the best practices for persisting hierarchical data? Is it possible to implement this using JPA annotations in state schemas? I have one state - TokenState , that contains some arbitrary data as well as a Collection of objects with the class TokenChild . The purpose of
