The idea behind this work is that the basic-network sample, which the FabCar sample currently uses, is an unrealistic network - it has one organisation w/ one peer, and does not use TLS. The first-network sample is much more realistic - it has two organisations, each w/ two peers, and does use TLS In this story, we will install Hyperledger Fabric v2.1 on the Linux machine. Everything may be hard when starting the new topic, so I try to collect all you may need in this story. Let's start. Hyperledger Explorer is a user-friendly Web application tool used to view, invoke, deploy or query blocks, transactions and associated data, network information (name, status, list of nodes), chain codes and transaction families, as well as any other relevant information stored in the ledger Hyperledger Fabric Gateway SDK for Java The Fabric Gateway SDK allows applications to interact with a Fabric blockchain network. It provides a simple API to submit transactions to a ledger or query the contents of a ledger with minimal code

Via Hyperledger Composer, and this introduces a totally new paradigm. While I have the highest respect for people working on Hyperledger projects, I have an issue with how it fits into the overall Fabric architecture, by having Composer re-create a Fabric network etc it seems it's going many directions/introducing unnecessary, extra processes, so, personally I'm avoiding this option The following Hyperledger fabric tutorial series consists of three articles which will teach you various aspects about Hyperledger Fabric chaincode development ranging from CRUD operations, data protection, and chaincode testing. Part 1 Part 2 Part 3. By Michiel Mulders An overview of the series: Article 1: Basic chaincode development and storing private data in collection To initiate fabcar you have to start the basic network and then access its blockchain using the fabcar network.
