Hi,

 

I am trying to submit large amount of data into a block in the chain. But because of amount of data size, decided to split document into several segments and save into next blocks in chain instead of storing data in one block. But even I split the data, facing with the error below. I am not sure that on the right way. As a first step, created a block for each row in the document and store data in the chain. But because of the poor performance, decided to change the strategy to split whole document. Can anyone suggest I am in the right way? And how can I fix this error? Is there any limit to store a document in a block?

Hello all,

I want to run some experiments for a custom chaincode I have developed. I am able to run a network (2peers/1orderer, using the fabric-samples/test-network) locally on a machine with the chaincode. After that, I use Caliper to benchmark the throughput/latency. Everything works well locally and I am able to obtain the caliper benchmark report. Now, I want to test it in a "real" setting. I want to deploy each peer as their own EC2 instance and then run Caliper on the network of EC2 instances. Does anyone know what is the best way forward? I looked at using the AWS ECS service as they have 1-to-1 mapping for the docker-compose.yml file used for deployment. However, setting the tls and crypto material is challenging task. Any tutorials or documentation you all can point to?

Thanks

Hi,

 

I am running my test application over IBM local blockchain test network by using VScode on a Windows machine. The problem is there some missing records after I executed js code. For example system execute submitTransaction method for 100 times, but I see ~26 records over CouchDB. Numbers are changing for each execute, but something around 25 records. I expect 100 records on CouchDB. Please find the code below;

 

    for (let i = 0; i < 100; i++) {

      console.log('Counter: ' + i);

      let response = await contract.submitTransaction('instantiate', 'orkun.gedik', 'This is a test message');

      console.log(JSON.parse(response.toString()));

    }

 

What may caused this problem?

 

Thank you for your co-operation.

Hey all, I am using Fabric v2.2 for a project of mine and I notice when I install a chaincode in the channel, hyperledger creates a new docker container (dev-peer0.example1.CHAINCODE_NAME). I wanted to know if there was anyway I can customize ZjQcmQRYFpfptBannerStart

Hey all,

I am using Fabric v2.2 for a project of mine and I notice when I install a chaincode in the channel, hyperledger creates a new docker container (dev-peer0.example1.CHAINCODE_NAME). I wanted to know if there was anyway I can customize the image used for this and prevent it from using the base fabric peer image. I want to do so because the other peers in the network (non-dev peers) are running a custom docker container (built on top of the base peer container). 

Thanks!
