Due to IBM doesn't provide free plan for IBM Blockchain anymore, I come up with with solution to integrate Watson IOT to Hyperledger Fabric instead of IBM Blockchain.
I found this document, it say that Watson IoT Platform blockchain integration supports connecting to both IBM Blockchain fabrics and Hyperledger fabrics
(in section Config Blockchain IBM environment)
But I can not find any guideline.
Anyone can help?
I have several related comments:
1) The page you linked to shows an early version of the IoT Contract Platform that I authored. I have not been funded to port it to Hyperledger v1 so it must be considered deprecated at this time. Instead, I suggest that you get comfortable with the Hyperledger Composer, which provides a huge development environment and a powerful data modelling language.
https://hyperledger.github.io/composer/introduction/introduction.html
2) Which leads me to IBM's free container service. If you want to get started with IBM Blockchain on Bluemix, you can create a free kubernetes cluster using the instructions found here.
https://ibm-blockchain.github.io/
The "create_all" script gives you a working fabric on a lite cluster (as in free) with hyperledger composer running (with playground) and with a copy of the example02 ubiquitous sample Go chaincode running on the same channel.
https://github.com/IBM-Blockchain/ibm-container-service
EDIT: As for the iot connection, you can use node-red to create iot apps that will catch your events on a topic and then forward them to the blockchain. This is for experimentation of course, but you will get the idea how an application must be written.
If you want to follow my "partial state as event" pattern in composer contracts, you can look at the deep-merge npm project and mimick that code while we wait for the node based chaincode that is coming in Fabric 1.1, at which time I hope that we can import it as normal in our business network js files.
Using deep-merge requires that you create your own transactions for create, replace, update and delete in your smart contracts, but these are straightforward. The bonus is that it is also easy then to emit custom events defining what happened to listening applications.
I think you will like these two technologies together.
Instead of using the IBM Blockchain, you should create your own Blockchain. You should use the Hyperledger Fabric for that. You have the documentacion about it here. I suggest you to start reading from the Building Your First Network chapter.
Then, you should integrate your Blockchain with the Watson IoT.

I'm tasked with creating a hyperledger application that will represent a consortium of same-skilled organizations.
I have the barebones prototype with a network of 2 orgs, built by following the fabric-samples example that I created as a capstone project; I am looking to upgrade the application to a production level.
My question is, is there a GUI/platform available to create and maintain hyperledger fabric networks?
What are the alternatives for tools like the Console?
What would be the best way to start building such an application considering the goal is to get to the production level?
Is IBM Cloud Blockchain Platform the best option for me?
Thank you for taking the time to reply.
I know of Hyperledger Console. I have used it previously for school projects. But can it be used to create and maintain+govern a production-grade HLF app?
IBM Blockchain Platform on IBM Cloud is withdrawn (https://www.ibm.com/common/ssi/cgi-bin/ssialias?htmlfid=872/ENUSWP22-0062&infotype=AN&subtype=CA). But the console is open sourced as https://github.com/hyperledger-labs/fabric-operations-console
I am trying to set up a rest API that is connected to an IBM blockchain resource. I have developed a model file, logic file, and acl file.
I have it all packed up in a nice tidy .BNA, and now i would like to deploy it to a channel of my IBM cloud blockchain 2.0 resource, running on a free kubernetes cluster.
Everything on the cloud blockchain resource is set up perfectly, and all orgs, peers, orderers, msps, and CAs are set up correctly. The channel is set up properly, and has nodes and an MSP connected. I have all the admin cred .jsons
The channel only accepts smart contract files, so I tried repackaging the files (logic.js, permissions.acl, and model.cto) by putting them in a contract folder, and using the IBM Blockchain vsCode plugin to package them as a smart contract, but trying to install on the IBM cloud crashes the browser.
I am thinking maybe I have to remote connect into the IBM kubernetes cluster that the blockchain resource is sitting on, and use the hyperledger composer CLI to install the .BNA
Seems very unintuitive, but thats the one thing I can think to try while I wait for this question to get answered.
I expected to just be able to install the .BNA as a smart contract, like a .cds.
In August 2018, IBM announced that we are no longer investing in Hyperledger Composer, and instead focusing 100% on Hyperledger Fabric. As a result, IBM Blockchain Platform v2.0 will not provide any support or tooling around Hyperledger Composer.
The good news is that we've significantly invested in the programming model (APIs and SDKs) used to write smart contracts and applications in Fabric v1.4, and we've also released some great developer tooling in the form of an extension for Visual Studio Code: https://marketplace.visualstudio.com/items?itemName=IBMBlockchain.ibm-blockchain-platform
The extension offers an extensive set of capabilities for writing smart contracts - with tooling for creating new projects, packaging them, deploying them, testing them, and debugging them - all from within one of the most popular IDEs around.
To get started - just install Visual Studio Code, and then the IBM Blockchain Platform extension (there are a few prereqs, check the README first). After that, you will be presented with a homepage that links you to tutorials and samples to help you get started.
For the first one, I can't really suggest a solution. At best, try installing and using the composer CLI and the latest version to make the bna file. Composer playground isn't maintained as well imo.
For the second part, in the connection.json file and docker there will be a bunch of IP addresses that look something like localhost:7040 and so on for the CA, orderer, org and peer. You will need to replace these using the IPs given by IBM. The examples on github that demonstrate integration are to do with nodejs SDK and not composer, however you can refer to https://github.com/IBM-Blockchain/vehicle-manufacture to get the idea.
This link is the only I could find for Hyperledger Composer and IBM platform.

I have setup a Hyperledger Fabric V1.0 Network by following the Hyperledger-fabric docs and using fabric-sdk-java client I am able to communicate with the network from my java application. Now everything is working fine in the development setup. But still I am not getting the clear picture about its production level implemenation. Looking for some valuable suggestions for the following points to make it production live.
Will it be possible to use this setup for production? then how can I build my network using this docker-compose setup? Which are the options available for production hosting of the network?
If it is possible to setup in production, should I run this docker-compose set up and all in all the peer system's, then how will I configure the docker-compose.yaml to define each of the peers/organisations which are in different system?
I have found Bluemix Blockchain Service as an alternative, but it is having high monthly charges. So is there any alternative to deploy myown Hyperledger Fabric V1.0 network by defining myown peers and organization?
I think that for a production deployment, you'd likely want to implement Swarm or Kubernetes. See Hyperledger Cello for instance. You will also want to have a process and automation for managing the code going forward. Updating images, chaincode, etc. Further, you might want to further automate some of the on-boarding process which at present is rather bare bones.
As noted above, the Docker Compose is designed for a single system. You'd likely want to use Swarm or Kubernetes to manage nodes on different systems and you want decentralized operations when you are engaging multiple entities into a consortia where the members want to choose where they run their nodes.
There is a developer sandbox offering that you can deploy to IBM's Container service (Kubernetes) but you won't be getting the benefits of the crypto acceleration, HSM, and added security of the LinuxOne platform on which IBM deploys the IBM Blockchain Platform. The good things in life may be free, but I would want to have the added value of a vendor provided cloud offering like IBM Blockchain Platform for my production system. YMMV.
Hi have been trying the hyperledger fabric 0.6 so far and was using IBM-Bluemix Block chain service to focus more on smart contract development. And now I am trying to use fabric 1.0 which provides more advanced features which suits my needs. But the problem is IBM-Bluemix service for the same is not available since the capacity of their beta reaches to maximum. So can anyone suggest if there is any alternative for this other than local dev environment setup since I have some security limitations in my system to install all the tools for the setup such as docker.
I am a product manager for Blockchain at IBM. If you use the Starter plan today (0.6) and are looking for a 1.0 equivalent, then check out the instructions here:
https://ibm-blockchain.github.io/
A final version of these instructions will be pulled directly into the Blockchain service on IBM-Bluemix in the coming weeks (pending an official announcement :) )
Let us know if you have any additional questions or feedback.
if you have access to AWS or similar services, you can take a look at https://github.com/litong01/fabric-deploy
I am planning to do a demo blockchain implementation for asset sharing among my application instances. For that I am using the Hyperledger Fabric V0.6 service provided in IBM Bluemix blockchain(starter developer plan beta).
But in Network tab it is showing the 4 peers as Validating Peer 0, Validating Peer 1, Validating Peer 2 and Validating Peer 3.
Will it be possible to rename this peers to some name which is closely related to my business to identify them easily?
Thanks in advance.
IBM Bluemix Blockchain service based on Hyperledger Fabric v0.6 will soon be removed. Instead, the new Blockchain service(currently it's vNext Limited Beta, based on Hyperledger Fabric v1.0) will be officially supported. So, I would recommend you to do the demo based on the new version.
Back to your question, you can not rename the peers. But in vNext, you can customize your channel names and also chaincode name&version
