of each transaction, generally for a transaction, short-term effective. Communication Certificate Tlscert: Control access to the network and prevent eavesdropping. The new architecture designCurrently, the VP node performs all operations, including receiving transactions, verifying transactions, agreeing on conformance, maintaining ledger maintenance, and so on. The coupling of these features makes node performance difficult to scale. The new idea is to decouple these functions so that e

I recently read a fabric, which is really a good thing. I suddenly wanted to use fabric to make a code version semi-automated O M management program and wanted to be fully automated. However, I am very comfortable with the front-end, it takes a lot of time to develop the front-end. There is really no time. Well, you can just write your own one in Python,The logical architecture is as follows:650) This. wid

Take fabric-samples/balance-transfer Example: 1. Specific process The FABRIC/EXAMPLES/E2E_CLI directory contains files network_setup.sh for one-click Deployment environments and test Chaincode sample code. This includes two sections, one that uses generateartifacts.sh script files to configure organizational relationships and issuing certificates, and the other is docker-compose-cli.yaml to start the clu

Installing fabric in a virtual environment (Virenv_python_django) hadoop@node:~/virenv_python_django$ pip install Fabric The error is as follows: SRC/MD2.C:31:20: Fatal error: Python.h: no file or directoryCompilation interrupted.

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

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 t

Blockchain Enthusiast (qq:53016353) The previous analysis program looked at the details of the analysis, so without the concept of framework, took two days to analyze the Hyperledger fabric architecture design, analysis of the program does not reference any information, such as error welcome correction, common progress. The author has the following questions before the detailed analysis procedure:1) How the CLI (command line) client sends a command to

". The app that initiates the transaction generates a "trading proposal" with the API interface in the Fabric Client SDK. The content of this proposal is to request the Chaincode chain code to read or write to the ledger. (A shim is a library that introduces a new API into an old environment and is implemented only by means already available in the old environment) the SDK of the fabric client (in the form

MySQL has a large number of cluster solutions, most companies use the master-slave, read-write separation, Galera this kind of multi-master program, very suitable for small and medium-sized enterprises. For large enterprises we need to divide the table, I have written 3 on the Sub-library function of the MySQL cluster scheme fabric, Cobar, MySQL Cluster, using these programs can simplify the sub-table library logic, speed up the development speed. Jus

Fabric engine is a versatile engine that is handy for writing node-write functions for software such as Maya. In particular, the canvas node editing panel, provides a large number of existing functions for users to call, of course, these nodes can be edited and modified by the user, in addition to provide a custom node function, very powerful and flexible.The initial fabric is easily confused by the various

Simple getting started with Python's automated deployment tool Fabric, pythonfabric Fabric is a Python tool based on the SSH protocol. Compared with the traditional ssh/scp method, it is easier to read and expand management commands written in Python syntax, managing one or more machines is like local operations. Address: http://fabfile.org InstallThe Installation Process of python and pip management tools

Fabric is a good tool for automating a peacekeeping deployment project that is developed using Python to automate interactions with remote servers via SSH, such as uploading local files to the server and executing shell commands on the server. An example of automating the deployment of Django projects is given below #-*-coding:utf-8-*-# file name to be saved as fabfile.py from __future__ import unicode_literals from fabric.api import * # login u

Fabric Smart Contract Specific Code template analysis The smart contract of fabric is called chain code (CHAINCODE), which is divided into system chain code and user chain code. The system chain code is used to realize the function of the system level, and the user chain code realizes the user's application function. The chain code is compiled into a standalone application that runs in an isolated Docker

Hyperledger Fabric Trading Flow Hyperledger Fabric v1.1 provides several special chain codes to perform certain special tasks, which are known as system chain codes (Systems Chaincode). The purpose of this paper is to summarize the implementation, function and usage of these chain codes. Similar to the user chain code, the system chain code also implements the Init () and Invoke () methods. There are five t
