问题 I am working with composer 0.19.8 to develop hyperledger blockchain app. My problem is that every time I make changes to the blockchain models I have to update the business network version in package.json and restart the fabric server in order for changes to reflect on Composer REST Server. If I do not do that the changes I made are not reflected on the rest server API(generated API by composer-rest-server command). Is there a way to override the current business network version instead of

问题 I just want to know whether we can use hyperledger composer in the scenario where there are multiple orderers deployed in kafka configuration ? 回答1: Hyperledger Composer can be used against any fabric network setup. So it will work with both a Solo Orderer setup as well as a kafka configured setup. However as noted in the comment there is a limitation in that although you can define multiple orderers in the connection profile, only the first one in the list is used to interact with an orderer

问题 I am able to add participant using composer-rest-api and it is possible to upload card through composer-rest-api by rest API wallet. Is it possible to create Card through composer-rest-api? I checked this answer Hyperledger Composer Web application user authentication, it mentions how to create card using javascript api. I used javascript code to create participant and issue it and when I run it ($node filename.js), it works fine. How can I add this to the rest API, which file exactly I need

问题 In Hyperledger we have something called a network admin and this admin will have access to all the cards and assets on the blockchain (at least I have tried to deny the admin access to assets using the acl, but I couldn't deploy the change, it timed out Everytime). So, is it possible to isolate admin from our business network? Or all the blockchains like ethereum too have the network admin? 回答1: I believe you are referring in your question to Hyperledger Composer rather than Hyperledger

问题 I want to instantiate a chaincode in an environment without any Internet connection. As the chaincode container will issue npm install upon instantiation, I added a new container called npmregistry in the docker-composer.yml so that it is provisioned alongside the rest of the Fabric containers and belongs to the same docker network (composer_default). Note I'm using the fabric-tools downloaded from https://hyperledger.github.io/composer/latest/installing/development-tools.html) npmregistry:
