    @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

    看样子好像是证书生成的时候出的错误,能帮忙看下原因么?

    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.

    Hi everyone, I have an issue with my HLF network implemented using docker. the docker logs are filling up all the filesystems. So each day I need to stop , remove the log and restart the dockers. It would be good to know if anyone has experienced with this issue? any expert in docker? I am assuming the log has some kind of dsebug or verbose settings … not sure

    When you are starting a nee project do you all also take a copy of byfn and edit the network according to your needs? Or is there some other way to start a project from scratch? Sorry if you find the question silly, actually I am a beginner 😅

    hi everyone
    while instantiate-chaincode they are using endrosement policy like this 'endorsement-policy': {
    identities: [
    { role: { name: 'member', mspId: 'Org1MSP' }},
    { role: { name: 'member', mspId: 'Org2MSP' }}
    ],
    policy: {
    '2-of':[{ 'signed-by': 0 }, { 'signed-by': 1 }]
    }
    }
    };
    can u please briefly explain what is the purpose of using this
    Thanks in Advance

    @tjfoc 你好 目前我按照你们发布的版本编译 和网上所有版本 ,遇到的错误类似,基本不可用。步骤:编译重新生成证书。首先遇到第一个错误就是Invalid DER for channel ,跟代码发现orderer/common/cluster/comm.go 中调用x.509Parse 错误,应该是调用同济的sm2.修改后能正常启动,创建通道时遇到panic: interface conversion: interface {} is sm2.PublicKey, not ecdsa.PublicKey,代码在msp/cert.go第92行,类型断言错误,代码没有判断保护直接panic,...
    有人指导怎么解决么
    这个代码目前可以直接用么 unsupported elliptic curve 我之前也遇到 就是那个Invalid DER 改了一个文件后错误消除 然后创建通道遇到断言错误 直接panic /。。

    Is there any way to delegate cryptographic operations performed by Hyperledger Fabric nodes(client nodes, orderer nodes, and peers) to Hashicorp Vault? Allowing peers and orderer nodes to sign and endorse transactions without exposing their private keys.

    Hyperledger Fabric officially supports HSM but I am unable to find any relevant document to do the same by replacing HSM with Hashicorp Vault.
