Any information will be useful Thanks,

Hello, How can I build my client application to run in container (or pod if k8s used)? Is there any example? I can not find something more than that Thanks,

Hello, I am looking to evaluate my BC network. So I am looking for directions like this. I am wondering what is the asset size and how can I find it in my BC network? Is the size of the payload during

Ok, it is just for debug. Any ideas will be helpful

Can I somehow (as admin of the network) get all the level DB key-values without querying the ledger via the chaincode? -- Nikos Karamolegkos R & D engineer at ICS-FORTH Telecommunications and Networks

Hello, in test-network what is the storage size of peers? In general, where can I find the peer characteristics (cpu, memory, storage) for the deployment? Also, using Level DB could you make an estima

based on this I have to func (s *smartContract) GetAirQNomVals(ctx contractapi.TransactionContextInterface) (string, error) { resultsIterator, err := ctx.GetStub().GetState("NominalValuesState") if er

the evaluateResult, err := contract.EvaluateTransaction("GetAirQNomVals") returns Invalid type. Expected: array, given: string - Transaction processing for endorser func (s *smartContract) GetAirQNomV

As I can see this functions returns car which is type *Car after unmarshal. Given that the EvaluateTransaction returns bytes can I bypass unmarshal and return carAsBytes from QueryCar (i.e return type

Hello, I use Level DB and I am using GetHistoryForKey to get the history of a key which return some records. Is there an efficient way to parse the returned records in order to find some specific valu

The purpose of removing the channel is that is not anymore useful for the BC network. The peers and the orderers are joined to another channel so how can I remove them from the useless channel? Is it

Any proposals for that? What is the flow (steps) I should follow for "removing" a channel? Is it enough just to unjoin the peers and orderers nodes?

Ok, I found the solution. I used wrong argument to CMD ["argument"] command of dockerfile

#chaincode

The error is failed to create shim: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "external": executable file not found in $PATH: unknown

I am trying to build my own custom chaincode based on fabcar. I have seen that if I change the module name in this line and then build the docker image I have problems with the deployment of the conta

#chaincode

If a channel is not useful anymore, is peer unjoin enough. I should somehow remove the orderers from the channel too.

Or to package only if a new chaincode name/label is created. Thus, to keep the same package when I just update a chaincode (i.e only increase the sequence number, and sync with the new docker image fo

Thank you. It is a bit confusing with the chaincode name and chaincode label. Nevertheless, is it bad to package each time the chaincode before the deployment? Even the chaincode name is the same?

Also, If I have already packaged my chaincode to tar.gz file with PACKAGE_ID= abcdf and I would like to use the same chaincode to a new channel (same chaincode functionality but different chaincode na

I think it is better to get the second option. I don't know which builder I am using. I deploy the chaincode as a service
