I'm starting to use Azure to host a multi node Hyperledger network. I've previously been running on a local environment, but would like to use Azure. I've deployed the 'Hyperledger Fabric Single Member Blockchain' template, which creates five VM's (one each for a CA, orderer and three peers). My local environment uses a CLI, but this doesn't seem to be in the Azure template. How do i interact with the blockchain network without the CLI? Are there any tuturials for how to use the deployed environment after its been setup? I've SSH'd to all of the three VM's that are hosting the peers, there

I am trying to pass in the channel configuration transaction artifact to the order-er using the command: peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem But I get an error: 2018-03-17 20:55:21.380 GMT [main] main -> ERRO 001 Fatal error when initializing core config : error when reading core config file: Unsupported Config Type "" What does this error mean? and how can

Is it possible to measure Hyperledger composer network performance which runs on Hyperledger fabric using Hyperledger Caliper framework? If yes can you guide me how can I change the configuration to connect Caliper to running Hyperledger composer network? If you use composer rest server to enable rest api endpoints, you can always use apache meter to test out the latency of your system. Hyperledger Caliper is a blockchain benchmark framework to measure performance of multiple blockchain solutions. I think the below links help you a lot.

I recently started up with composer tutorials and now I am confused if it is boot starting block chain application development or block chain network development. Do we need to create a block chain network using fabric and than integrate it with composer to create rest end points and angular application for our fabric network? can we achieve decentralizing and immutable transactions by just using composer? The answer is it is "bootstrapping" application development (Composer helps get you started, by installing a 'development" Fabric setup - although you could use just Composer playground too

In case of Bitcoin transaction the verification/validation involves looking at the input UTXO balance etc... But in Hyperledger the transaction (if I may) "just" carries the data (function name and data-string) for the target smart contract. Does it mean that there is no necessity of validation (apart from the syntax) of the transaction? If yes what has to checked and against what? Can anyone pls give me an example use-case? If there is no validation, then is my understanding correct that the blockchain is "just" a ledger without any verification on the transactions. If something goes wrong
