问题 I have a composer-rest-server running on localhost:3000 . To go with that, I tried to generate an Angular 2 app using yo hyperledger-composer . My business network models also have a abstract concept Spray{...} present. I believe the documentation is outdated as I was presented with slightly different options than on the documentation. After choosing Angular and following through the steps, I got an AssertionError: Trying to copy from source that does not exist ... /concept/concept.component

问题 Looking at securing confidential information in Hyperledger Composer If assets and transactions in a business network have ACL's to prevent a competitor participant (non-owner) from viewing confidential information, what access can the competitor have to assets and transactions owned by another participant?

问题 I have tried "carauction-network" example in my local. But when I am starting the network by using "startFabric.sh" file, it is removing the Couch DB & again creating Couch DB, due to this old data are getting lost. Please suggest how we can start the fabric server without cleaning the data. 回答1: The startFabric.sh under fabric-dev-servers (formerly fabric-tools) does more than just start the Fabric - it removes existing Fabric Containers and recreates new Containers from the Docker Images.

问题 I spun up an Ubuntu server on AWS and everything is working as expected with Hyperledger Composer except when I try to compile an angular-app using "npm start" after creating the app via "yo hyperledger-composer:angular". Its taking forever to compile at 92% chunk asset optimization. When I do the same exact steps on my local mac laptop, no issues at all. Must be some sort of version issue with something in the node_modules? Any thoughts or suggestions? 回答1: probably because your AWS VM
