    Hi..I am new to hyperledger..I am trying to create 4 diferent channel in 7peers and one orderer network..do we have to create separate genesis block for each channel
    mxz-scott
    @mxz-scott
    @TejPandey 使用工具configtxgen 生成的genesis block 是ordere 节点启动需要的创始区块用于引导排序服务,createChannel 命令的产出是一个创世区块-<your_channel_name>.block-这个创世区块被存储在peer节点的文件系统中同时包含了在channel.tx的信道配置,详细参见:http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html

    根据fabric-gm编译了peer、orderer、tools镜像,启动、创建channel、安装chaincode没有问题,但是在初始化(instantiate)时,报找不到“fabric/core/chaincode/shim”、“fabric/protos/peer”包,不知什么原因,pull的ccenv是1.02版本

    @cmal 我们的fabric-gm是基于fabric 1.02的,而上述问题是在fabric1.1中的,我们还没研究过这个版本,所以回答不了您的问题,抱歉。

    trying to run hyperledger fabric network through nodejs chaincode , but it specifies -l as an illegal option!
    but in documentation the command is given to run it through nodejs.
    Hitesh Paliwal
    @hiteshpm
    -l menas you have to mention language name as node because bydefault it will take name as go lang

    @sooraj-citta
    @mxz-scott I am new to hyperledger but from what i understood, this script file pull and start the docker containers for basic hyperledger fabric , couchdb etc. So sometimes this error comes up. I have no clue. I always to the ./teardownFabric.sh to kill & remove the existing docker before attempting to start a new one..

    Hi ,How can we create publickey for user when he registered and with that publickey he can create his won privatekey ,is it possible to do so in hyperledger. And these keys should not stored in ledger.
    mxz-scott
    @mxz-scott
    你可以使用 cryptogen 工具生成密钥和相关证书文件,或者调用bccsp的加密接口生成公私钥对,这些密钥会存储在你配置的keystore目录下

    我在调用cryptogen生成证书的时候报错了,使用的是e2e_cli下的配置文件,cryptogen generate --config=./crypto-config.yaml,报了以下错误:org1.example.com

    Hi everyone, Can anyone suggest a good provider of Blockchain as a service ?

    I think if you can blindly trust other parties to have your infrastructure and centralize it for the whole network, then a blockchain is not what you need.
