Introduction
In this article, we will build a simple blockchain network with Hyperledger Fabric. Fabric allows us to build a private blo...

Did you test this code before posting?
You generate the genesis block as "genesis.block" and later on use "orderer.genesis.block"
../bin/configtxgen -profile OrdererGenesis -outputBlock ./channel-artifacts/genesis.block
...
You also require "Template" in crypto-config.yaml, otherwise the crypto is not fully generated.
PeerOrgs:
It's also illegal to use capital letters in the naming of channel! The ordered will crash.
Actually, changing
'ORDERER_GENERAL_GENESISFILE=/var/hyperledger/orderer/orderer.genesis.block'
to
'ORDERER_GENERAL_GENESISFILE=/var/hyperledger/orderer/genesis.block'
breaks the code, because '/var/hyperledger/orderer/genesis.block' does not exist.
The original code was correct because in docker-compose-base.yaml, you mount the following volume:
../channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block
can you please share you github link for this code ? It will be very helpful
However, after fixing this, Ithe orderer fails to start with the following error:
' Error creating configtx manager and handlers: Error deserializing key Capabilities for group /Channel: Unexpected key Capabilities'
Using the latest fabric images (i.e. removing all instances of ':x86_64-1.0.0-rc1') fixed this.
Thank you for your comment. I had no idea about the capital letters in the channel name causing problems! Thanks!
Hi, Thanks for this very good article of you. Though seems like you've got a wrong pattern of configuration in configtx.yaml. When I tried your configuration I've got an error. And so I put the Profiles at the very end of the file and it works. I think you should put the Profile then at the very end part of the file. Thank you.
when I try to create a channel after setting up this network It is giving me an error of like this.

Usage:
peer channel create [flags]
Flags:
-c, --channelID string In case of a newChain command, the channel ID to create.
-f, --file string Configuration transaction file generated by a tool such as configtxgen for submitting to orderer
-t, --timeout int Channel creation timeout (default 5)
Global Flags:
--cafile string Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint
--logging-level string Default logging level and overrides, see core.yaml for full syntax
-o, --orderer string Ordering service endpoint
--test.coverprofile string Done (default "coverage.cov")
--tls Use TLS when communicating with the orderer endpoint
-v, --version Display current version of fabric peer server
I tried it with this command.
peer channel create -o orderer.cool-network.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.t
x --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/cool-network.com/orderers/orderer.cool-network.com/ms

Can you help me to solve this problem? Thank you.
I m also facing same issue.
Not sure if this is an error, but shouldn't:

Hi Damien,
I successfully started the network created using your tutorial above. Now, what I am trying to do is install a business network archive file in one of 3 organizations but unfortunately I encountered an error doing that. I don't if it is because of the version. Because I also followed the one that use the first-network and I successfully install the file in the network. Version used in first-network is 1.2.0.
Hey Damian, thanks for this article. Now, where can I find the next article related to this?
Thanks for the well written article.
My question is what is the role of
MicrosoftAnchor.txI don't see it referenced in the docker compose files.
Thanks
very helpful article
How can we write chaincode and maintain ledger after this? Please guide.
