HyperLedger fabric chaincode not updated

问题 I am trying to follow along this sample Hyperledger Fabric code: https://github.com/hyperledger/education/tree/master/LFS171x/fabric-material Initially I replaced chaincode/tuna-app/tuna-chaincode.go with my go file chaincode/tuna-app/test.go. test.go had changes just in what we initialize in the ledger through its initLedger function call. It worked fine, with no changes required in tuna-app/.startFabric.sh. Now when I again try to change the ledger through its initLedger function call, its

I have started playing atound with Hyperledger Sawtooth recently, and having trouble to submit transactions on java, while python code seems okay. I have prepared the python code based on the api docs here and then tried to write one in java as well. Below is the code in java import com.google.protobuf.ByteString; import com.mashape.unirest.http.Unirest; import sawtooth.sdk.processor.Utils; import sawtooth.sdk.protobuf.*; import java.security.KeyPair; import java.security.KeyPairGenerator; import java.security.Signature; import java.security.spec.ECGenParameterSpec; public class BatchSender {

How to use a chaincode that's not on github?

由 吃可爱长大的小学妹 提交于 2019-12-01 06:30:49
问题 I have developed a chaincode using this and now that I know that it works I want to test it in a network with multiple nodes. Where should I put my chaincode so that I can deploy it in the Hyperledger fabric network? I have used this to setup the network. 回答1: There are two options: If you are not using a docker image to start your nodes then you should deploy the chaincode by specifying a fully qualified path, in other words, you should set the parameter when deploying: -p /home/user/my

HyperLedger Fabric的fabric-sdk-java的End2endIT测试

由 假装没事ソ 提交于 2019-12-01 01:44:00
博主搞了很久环境和调试，哎，一把泪，现在总结下。免得大家在采坑（可能是我运气不好，可能有些人没有） 最近想搞下Java-SDK来连接Fabric进行操作，首先来进行End2EndIT的官网提供的测试类进行测试。 1.连上云服务器（或者自己要搭建的虚拟机），最好是跑通过e2e_cli实例，免得环境有问题。 2.切换目录到/opt/gopath/src/github.com/hyperledger下（默认的Gopath目录） 3.拉取官方的End2End代码，git clone -b release-1.1 git@github.com:hyperledger/fabric-sdk-java.git(我是直接拉取1.1版本的代码，不建议拉取1.0的代码，为什么，后面会说) 4.切换目录到./fabric-sdk-java/src/test/fixture/sdkintegration 5.进行启动./fabric.sh up(最好是每次启动前进行./fabric.sh down 关闭网络，进行环境清理) 6.出现以下提示，基本就完成了网络环境的启动 7.进行Java-SDK的测试，一样将代码拉取下来git clone -b release-1.1 git@github.com:hyperledger/fabric-sdk-java.git，放在电脑合适的目录下 8.打开IDEA

Issue while using fabric client java sdk (since there is no Rest API support) in local development environment for Hyperledher Fabric V1.0

I have done the following as per the suggestion that I have got from my previous post to communicate with locally running Hyperledger Fabric V1.0 network from java application. But I am getting the exceptions given below and unable to sort it out why it is happening. public class Test { final HFClient client = HFClient.createNewInstance(); Channel channel; TransactionProposalRequest proposalRequest; void setupCryptoMaterialsForClient() throws CryptoException, InvalidArgumentException{ // Set default crypto suite for HF client client.setCryptoSuite(CryptoSuite.Factory.getCryptoSuite()); client

Hyperledger: get “/bin/bash: ./scripts/script.sh: No such file or directory” when running “./byfn -m up”

由 荒凉一梦 提交于 2019-11-30 21:33:17
I'm a newer for the hyperledger and just studying it by following the tutorials on http://hyperledger-fabric.readthedocs.io . I am trying to build the first network using "first-network" in the fabric-samples. The ./byfn -m generate is OK. But after typing ./byfn -m up , I meet /bin/bash: ./scripts/script.sh: No such file or directory error and the process hangs. What is going wrong? PS: The OS is Windows 10. Check to see if you have a local firewall enabled. Depending on your docker configuration, a firewall may prohibit the docker daemon from accessing share drives as specified in docker
