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:

问题 I have successfully create a Hyperledger Fabric v1.0 network locally by following the steps Building Your First Network and communicating to this network from my java application using fabric-sdk-java. Here it created the certificates using cryptogen tools and is able to invoke/query chaincode through each of the peers which participating in the same channel. My implementations is like: I have four organisations Org1, Org2, Org3 and Org4 each having one peer. When Org1 creating an asset A1

问题 I have a Hyperledger Fabric network setup with 3 peers, each with a CouchDB persistence container. If I go through the Fauxton interface and alter a JSON record, this state change is propagated to all three peers, which are in the same org. However, there is no record of the state change in the blockchain. No transaction is created for it. If it's not a blockchain transaction causing the state change to be propagated to all peers, what mechanism is causing it? How in the heck is the state

问题 My team and I are developing an app using Bluemix Blockchain services, and we were using the application just fine until the 1.0 update. We thought it could be an error related to the ibm-blockchain.js library, however we have tried deploying it via REST and we still get errors: { "jsonrpc": "2.0", "error": { "code": -32001, "message": "Deployment failure", "data": "Error when deploying chaincode: Error getting chaincode package bytes: Error getting code 'go get' failed with error: 'exit
