Hi Nikos, I have done this within my company and I prefer to issue identities to the end devices as we would the users. We do not use an intermediate DB as we use our Fabric blockchain network

Hello, I want to build a smart building IoT BC network and I am working to the network architecture. At this point I have built the IoT infrastructure and I am looking to integrate the BC idea.

Remember that chaincode execution is only a transaction simulation that builds a read/write set. The transaction doesn't get validated and committed until after it is ordered into a block. Therefore

You should also take a look at attribute based access control in chaincode, to authorize users to chaincode actions based on issued role attributes. See the sample and linked docs:

Hyperledger Fabric fix releases v1.4.12, v2.2.3, and v2.3.2 are now available. See details of the fixes in the release

Hi Fabric maintainers, As some community member and me found for a while, Both following repositories have no git tags yet pushed to

Thanks Gary, This seems to be working now :) I will probably write a blog around how to integrate AWS Cloudhsm with hyperledger components.

Make sure you are using the latest version of Fabric CA. With the AWS HSM, you need to add "AltId" to your bccsp configuration: bccsp: default: PKCS11 pkcs11: Library:

Thank again, guys. When I configure fabric CA to use AWS HSM it crashes with the below error, My BCCSP configuration looks like this, Any pointer would be really helpful. Thanks Shantanu

Brian, Sorry, I sent you the command for earlier fabric networks which would be correct if you are on Fabric 1.x If you are on Fabric 2.x you will need to use the new peer lifecycle chaincode

Hi Nikos, In general, each party involved in any transaction should be in its own org. With that in mind, it is not a good idea to have only one org as this creates multiple problems (single point

Hi, What kind of external services are we allowed to use in fabric? Can we use any APIs? Or we must just use fabric SDK. For example, an external service is a bank ATM API, and our transaction is
