What has been harvested and what has been done is an important issue.This article is only to learn to exchange information, personal summary. A brief analysis of Hyperledger fabric PBFT algorithm Architecture Fabric Consensus algorithm code is all in the Consensus folder, consensus folder is mainly divided into Controller,executor,helper,noops,pbft,util file module.Among them, consensus.go mainly contains the internal interface of the algorithm plug-i

First, preparatory work 1. Through the tutorial-"(i) Hyperledger fabric in the CentOS7.2 64-bit system development environment build" to determine has been downloaded Hyperledger Fabric official sample codes. ii. generation of networks 1. Generate Network Identification CD Results after successful execution: 2. Start Network ./byfn.sh–m Up Startup success: Intermediate output slightly Go is t

the Go programming language installed and your system is configured correctly. Now you need to create a subdirectory under your $gopath/src/to store your link code program. To make things simple, we provide a simple instruction: Mkdir-p $GOPATH/src/sacc cd $GOPATH/SRC/SACC We create a source file: Touch Sacc.go Housekeeping (coded) First let's prepare the code. Like every chain code, it implements the Init and invoke functions of the chain code. So let's use the GO Import statement to impo

Hyperledger source code Analysis of Fabric Deliver means that the client obtains data from the ordering service via the Grpc interface (for example, data from a specified block). The Orderer node receives the request message, which is first given to the Deliver of the server structure in the Orderer.common.server package (SRV ab. Atomicbroadcast_deliverserver) Error method processing. This method further invokes the Handle of the deliverserver structu

Hyperledger source code Analysis of Fabric Broadcast means that the client sends the request message (for example, after the endorsement transaction is completed) to the ordering service via the Grpc interface. These request messages are given to the broadcast (SRV ab) of the server structure in the Orderer.common.server package. Atomicbroadcast_broadcastserver) Error method processing. This method will mainly call the Handle (SRV ab) of the HANDLERIM
