Hi Fabric Community, I'm exploring the offline transaction signing flow in hyperledger fabric by using Fabric Node SDK. I came across the following official tutorial. https://hyperledger.github.io/fab

Hello Mark, Thank you for your reply. I will discuss with team here if we are good to go with off chain approach or just remove the date filter and fetch blocks, batch wise, like fetch blocks from lat

Hello, I have a HLF running on azure AKS cluster. I have a couchdb acting as a wallet to store the identities of the blockchain admin and users. It is hosted along with all the other pods. when i crea

If you do want to provide your own implementation of how the client waits for a submitted transaction to be committed by network peers, this tutorial has some useful information: https://hyperledger.g

There look to be two issues here: You are listening for a transaction ID that you never submit, so no commit will ever occur. You are attaching your commit listener after the commit has occurred so it

Hi, I can run and test my Smart Contract manually using command like this without any error: peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls true --cafil

Good day, Thank you for your reply! And apologies for my late reply. For the TLS certificates, I used the registerEnroll.sh script that is included in the test-network files (in /test-network/organiza

Those certificate verification failures during the TLS handshake look like a problem to me. I guess the node certificates are not valid for localhost. Maybe you could add entries to your client's loca

To close the loop on this one... we found that two peers were configured to use a single CouchDB database, and therefore the peers were stepping on each other and getting inconsistency between peer da

I think I don't need to change any msp or tls files unless they are expired when upgrading the network. How can I use the TLS CA certificate I was using on v1.2.0 network after upgrading to v2.2.2? He

Yes, docker is installed and local network is up. This is happening at npm install stage likely when chaincode docker image is built.

Hi Team, We were investigating to use Azure Key Vault to provide for our wallet services. The CSR, Private and Public Key is basically generated by the Vault and saved securely in the same location. T

Hello Tingli, I have verified with fabric v2.2 and it works fine. We can invoke any qscc from fabric-network sdk. Thank you. Heartfelt Regards, Pavan Adhav Blockchain Developer, Infinichainsphone: 839

What is the difference between the two? When to use which?

Hi All, I've managed to invoke the qscc chaincode to retrieve the transaction serialized response. My question is how do I deserialize it in node.js to get some relevant info out of the same? Can it b

The v2.2 Node SDK does not have the specific support in its API for deploying chaincode that the v1.4 Node SDK had. This is down to the development effort required to produce and continue to maintain
