Difference between users created through cryptogen and enrolled through Fabric CA Server

由 烂漫一生 提交于 2019-12-10 10:20:28
问题 While doing Hyperledger fabric setup, we create crypto material and mention users for organizations and and correspondingly user crypto material gets generated which is used to invoke chaincode while logging through CLI. Also, when we try to connect network through SDK we also need to enroll and register user to connect to network. So, what is the difference between these two users? 回答1: Cryptogen utility used for generating Hyperledger Fabric key material is mainly meant to be used for

区块链100讲：Hyperledger Explorer简介

由 旧城冷巷雨未停 提交于 2019-12-10 00:18:24
上一篇我们介绍了面向运维的Cello项目，可以帮助运维快速部署与监控各个区块链节点。今天我们将介绍另一个类似的项目 —— Hyperledger Explorer。 1 项目简介 Hyperledger Explorer是一个区块链的图形化explorer，具有使用简便，功能强大，易维护等特点。同样也是Hyperledger众多项目下的一个子项目，目前还处于孵化中。 如果说Cello是一个面向于运维的图形化工具，那么Hyperledger Explorer就是一个面向于开发人员和普通用户的一个图形化工具，提供web界面，用户可以容易的看到区块链上的活动，有点类似于以太坊项目中的 https://etherscan.io/ 2 环境依赖 由于需要fabric, docker等一系列依赖，我们依旧选用Ubuntu 16.04系统，主要依赖如下: 软件运行依赖: nodejs 8.11.x (Node 9.x暂不支持) PostgreSQL 9.5 or greater 要工作在Hyperledger Fabric 1.1以上网络中，需要运行以下依赖管理fabric网络： docker 17.06.2-ce [ https://www.docker.com/community-edition ] docker-compose 1.14.0 [ https://docs.docker
