What is Hyperledger?

Hyperledger is a Linux foundation hosted business Blockchain projects.
There are five variants in the Hyperledger.
Sawtooth — Adding modularisation for distributed ledger, it implements POeT consensus mechanism in the blockchain.
Iroha — Simple and easy to incorporate the blockchain systems.
Fabric — Modular architecture, consensus mechanism, membership systems.
Burrow — Permission-able blockchain, smart contract machine which is used from Ethereum Virtual Machine.
Indy — Blockchain tools, libraries and reusable components for providing digital identities.
Hyperledger Tools
Cello — On demand “as a service deployment model to create, manage, terminate blockchains”
Composer — Collaboration tool for creating Blockchain business networks, accelerate the development and deployment of smart contracts.
Explorer — Can use to view, invoke, deploy or query blocks, transactions, get network info, deploy chain codes, find relevant information in the ledger.
We are going to the different variants of hyperledger, starting with Fabric. Which is quite popular in the community.

Hyperledger Fabric

Fabric is a business blockchain framework. Which is having a modular architecture.
It contains two major components
  1. Consensus
  2. Membership services, to be used as plug and play.
It helps to bring confidentiality and scalability by establishing trust, transparency and accountability. Other advantages
  1. Permissioned network
  2. Confidential transactions
  3. No cryptocurrency
  4. Programmable smart contracts
Important concepts related to Hyperledger Fabric
  • Blockchain Nodes
  • Permissioned
  • Public or confidential transactions
  • PBFT algorithm
  • Chaincodes
  • Golang, Java languages
Simple explanation Hyperledger Fabric, https://www.youtube.com/watch?v=js3Zjxbo8TM
Nodes are separated into three
Peers → endorser + committer
Consenters →consenter
Using Fabric, without passing everything through a central authority we can transfer data.
Transaction Flow in a simple way,

Initiating Transaction → Building Transaction proposal → Ordering the transactions →Validation and commit

→ Blockchain in business is a decentralized system for the efficient and secure exchange of business assets.
→Stores history of the asset transaction between members.
→ For additional confidentiality, members can join specific channels that allow data isolation.
→ Participants on the network agree on the consensus on the update to the records in the ledger. No third party involved.
→ Every record in DLT is having a timestamp and a cryptographic signature. It makes ledger auditable.

I am assuming here that you are familiar with HTML and CSS. I have commented the code with the necessary information in the major part of the code. So you can understand easily. I have also attached the source code so you can download it and use it. Let's start. Note: I have updating this article on my personal blog. The following are the points we will be learn in this article: Creating Database in phpmyadmin. Create connection with MySQL database. Insert, delete and view data from MySQL database. Some Bootstrap components. Sessions in PHP. Files and IDE: Registration Login Logout Welcome Admin_login View_users Db_conection Delete.php I am using PHPStorm for the coding and Bootstrap framework for front end development. Create Database: Create Tables: Create columns in Users table: Crate Admin Table: Create Admin Columns: Registration.php: <html>   <head lang= "en" >       <meta charset= "UTF-8

Real-Time Web Interface to MQTT using Socket.io and Node.js

Real-Time Web Interface to MQTT using Socket.io and Node.js First, all credit for this tutorial goes to  Robert Hekkers Blog .  I've altered it slightly to pick up newer versions of the various javascript libraries. If you've followed along with my  earlier post , you now have MQTT running on your Raspberry Pi, and an Arduino IoT client that can publish and subscribe to MQTT packets.  The next step is developing a real-time web interface that can control your MQTT network. Why Socket.io and Node.js? Web browsers typically operate by pulling data from a server when you click on a link.  Servers don't usually keep an open connection to the browsers it has serviced, so if some event happens on the server side, the server cannot push that event to your browser, unless you refresh the page. That's where Socket.io comes in handy.  Socket.io maintains an open connection between the server and the browser, which enables the server to push updates to the browser as they

Customize radio buttons and checkboxes with CSS sprites

To replace a radio button or a checkbox with a sprite, you first need to create the sprite image. For this free tutorial, we use the following sprites: Create the HTML Once you’ve created your sprite images, you will need to create the HTML. Below you will find the HTML we created for this demo. If you need more information about this, consult the following article:  Customize radio buttons and checkboxes with only CSS Radio buttons HTML: <input type="checkbox" id="checkbox-default-1" name="checkbox-default" class="default"> <label for="checkbox-default-1">Checkbox 1</label> <input type="checkbox" id="checkbox-default-2" name="checkbox-default" class="default"> <label for="checkbox-default-2">Checkbox 2</label> <input type="checkbox" id="checkbox-default-3" name="checkbox-default" class="default&
