Select wallet identity

Nikos Karamolegkos

#10577

Hello, I am studying the wallet functionality from here. I can see that the user Isabella can have multiple identities so I understand that in the chaincode I can verify not only the user but the identity (e.g ID1, ID2) of the user too (who invoked the transaction). Therefore, my questions are:
1) Is there any code sample that does that verification inside the chaincode?
2) How can select from my client application a specific ID from the wallet in order to invoke the transaction? (eg. ID1)

Thanks,

From my understanding. MiniFabric is not a Production Release. It's just a tool used to understand fabric easily. It's just kind of "Example" for test network. but not a tool used to deploy production environment

Sometimes I really doubt about the value of the MiniFabric. It did help to build a fabric test network quickly. But it also conceal lots of details/concept that are important to understand fabric components(orderer, peer, ca, even docker etc.). The result is Veterans are happy to use it for time saving. The beginners are always confused to the MiniFabric introduced command, configuration, purpose etc.

Hi Everyone,
I have some questions with respect to Hyperledger MiniFabric. Kindly help me with respect to it:
1) Shall I use Minifabric to implement any application?
2) Which database is used by MiniFabric (LevelDB or CouchDB)?
3) Are there any constraints while using MiniFabric?
4) Is it good to use for our applications?

Thank you.

With regards,
R.Sasikumar.

Re: How does a peer know there's a certificate authority in the same Org? #fabric-peer #fabric-ca

gerald li <xixisese@...>

#10574

It relates to how the CA works. The peer knows the Root CA of the Org through the peer's MSP files. It can then verifies the incoming certificates against the Root CA.

Just as verifying the certificate through the command line:

openssl verify -verbose -CAfile <Root certificate> <certificate>

Hi, I was reading the source code of hyperledger fabric, and reading the log of a peer in a DEBUG mode.

I wonder how fabric peer know the information of the certificate authorites of its own Org?
For example,
(1) address: I didn't find it
(2) name: I didn't find it
(3) pem file: pem file is detected when starting a peer inside /internal/peer/node/start.go, the method serve()

Thanks in advance.

Building a Blockchain one Business Unit at a time

#10573

I would like to create a Private Blockchain:
1. A single Organization: www.myorg.com
2. In this Org, I have 3 Regions: USA, APAC, EMEA
3. The Organization has a Primary CA for all three Regions.
a. Org has three business units (BU) that are comprised of three Departments: Legal, Finance, and Operations
(1). Each BU maintain their own secrets that are not visible to other Business Unit Users
(2). There are some files or assets that are public and available to everyone
4. There is a Master key that allows access to every asset in the corporation

How would I create this environment in miniFabric?

Re: Expose Hyperledger as REST

Matthew White

#10568

There are several examples of how this can be done written by different community members. A basic example is very simple to create, a POST for example is mapped to a submitTransaction. You could use any REST framework and any language you wish. There are some sophisticated examples that will create the REST API automatically based on the contact metadata.

Some of the challenges that you'll come across in a production scenario.

- How are fabric identities used for submitting to the transactions held and used. Are they somehow past via the REST call, or held by the REST Server?

- Will a single rest server front more than one contract? Think about the pooling of connections to fabric, and how these are reused and recreated

- Depending on the number of endorsements required, a Fabric transaction could take some time to complete. REST calls are intended to be much quicker - you might need to think about a polling system so any UI is kept responsive.

Hello Johnny,

We will fix this compilation messages soon, but do not worry, your HL Fabric is good to go.

Do not forget to run the script:

This will allow you to use the web app integrated with your chaincode.

Hello,
I have tried to setup the development environment, from some reliable sources of installation, such as GoLedger; however, my results are not as described on the Goledger pages. For example, I am not getting the Install network Chaincode portion in the report when I call ./startDev.sh. Please see below.
I tried to update the prerequisites sh file to install the latest version of Golang and Node as well as running the sh file that installs the prerequisites as is, but the results are the same; they do not match the goLedger instructions page and getting lots of errors in the reports: GoLedger

I am getting errors and can't verify the results because they do not match the instruction pages from GoLedger.

My name is Sam, from the GoLedger team.

We have since removed the networkChaincode functionality and this output from the documentation is outdated.
As long as you get a SUCCESS during the Chaincode Instantiation you’re good to go.

I apologize for this inconsistency and feel free to contact me if you need anymore help with cc-tools.

Hi Sasikumar,

1. For adding a new organization like Org3, you can follow the link below:

https://hyperledger-fabric.readthedocs.io/en/release-2.2/channel_update_tutorial.html#bring-org3-into-the-channel-manually

Note: Modify MSP Id according to your needs.

2. Yes. You can create more than one channel. For detailed instructions, please have a look at following link.

I have successfully executed the test-network which is available in the fabric-samples folder. It creates Org1 & Org2 with one peer each. If I need Org3 in my network, I can use the addOrg3.sh script file inside the addOrg3 folder. But my questions are:

1. Like the Org3, I want to add more Org (Ex: Org4, Org5) in my network and also I want to change my Organization name(Ex: "Hospital" Instead of Org1) depending on my application. How can I do it? Which script files or yaml files do I need to modify?
2. Is it possible to create more than one channel in my network structure? and each channel can have different Organizations. (Ex: channel1 for Org1, Org2, Org3. & Channel2 for Org1, Org2, Org4 likewise)

Kindly suggest detailed tutorials or videos link for the same.

Thank you.

I have tried to setup the development environment, from some reliable sources of installation, such as GoLedger; however, my results are not as described on the Goledger pages. For example, I am not getting the Install network Chaincode portion in the report when I call ./startDev.sh. Please see below.
I tried to update the prerequisites sh file to install the latest version of Golang and Node as well as running the sh file that installs the prerequisites as is, but the results are the same; they do not match the goLedger instructions page and getting lots of errors in the reports: GoLedger

Hi,

If you're just getting started with Fabric development, I suggest using minifab to get up and running:
