Hi Team, in peer logs we keep seeing following error messages: ``` 2021-01-12 14:36:08.217 UTC [core.comm] ServerHandshake -> ERRO 2278 TLS handshake failed with error read tcp

Hi David, That's correct! However, we found a minor fix in the chaincode and post that the latest error logs give following stack trace: ``` [34m2021-01-12 09:22:03.362 UTC [endorser] callChaincode

Thank you for your email. Yes, we are going to update this tool. Support for channel participation without system channel is one of the future features. Tatsuya Sato

If you do not like to write boilerplate code repeatedly, or spend time to learn a new programming language supported by the Fabric chaincode. You may want to check this out:

I like your idea of managing chaincode and channels using blockchain. Fabric v2.3 has removed the dependency of system channel and consortium. Are you going to update the tool accordingly?

Your first log snippet showed CouchDB queries timing out after 35 seconds each. This is the core.yaml ledger.state.couchDBConfig.requestTimeout of 35s. It means that CouchDB is still processing the

Thanks a lot David for your response. So digging deeper into the logs, we found that peer was returning below error: [chaincode] BuildQueryResponse -> ERRO Failed to get query result from iterator

Adding workarounds such as longer timeouts will only prolong your pain. You must address the root cause of the slow query in CouchDB. Troubleshoot it in a separate CouchDB environment until you have

Anyone could help with this one? I was thinking I have something wrong with the volume what I’m connecting to the container in k8s, but it looks correct. This is the files structure in the

Hi David, The chaincode is performing a select query on the CouchDB documents, and the fields set for filtering the results are indexed while installing and instantiating the chaincode. The single

Hello, We just released the first version of Operations Smart Contract (OpsSC) for Hyperledger Fabric v2.x. This is a smart contract-based system operation tool for Hyperledger Fabric-based

Nathan, There are some solutions out there along these lines, including our partner Vottun’s PROOF OF HEALTH CREDENTIALS built on Fabric and available on Oracle Blockchain Platform, but could

Thanks. chaincode-go has the same API, shim.GetMSPID(), which returns the value of env CORE_PEER_LOCALMSPID.

Hi Samyak Jain, Just to add on top of the approach David suggested. You can use the block event service to do much more like pushing important data to various systems (not just data stores). In the

Hi everyone, Has anyone explored the use of fabric for covid-19 immunity passports purposes? These peer nodes could be setup and managed by the various governments, the WHO, etc. Once vaccinated, your

Hi, If I get your questions right, you want to fetch the MSPID of the peer that starts/endorses the chaincode. For that purpose you can use the chaincode shim API. In case it is java based chaincode

when my chaincode wants to write to the implicit private data collection, I need to get the local MSPID where the chaincode is deployed. What is a good way to get it? check the ENV of

Thanks Yacov, but I don’t intend to create the admincerts folder. “define the admin OU in the config.yaml of the MSP folder” This is exactly what I’m doing -> This is the config.yaml from the
