Study material for Certified Blockchain Developer (CBD)

This lecture will help you to understand the Blockchain-as-a-Service model and who are the major players providing this service.

In this lecture, you'll understand why Blockchain-as-a-Service from Azure and why not from someone else and why we should not setup our own Blockchain.

This lecture will help you to know what are the different options we have in the Blockchain when we talk precisely about the Azure solutions.

Ethereum is an open source Blockchain based distributed computing application platform. In this lecture, you'll know about the Ethereum fundamentals and its working.

This lecture will help you to understand the concept of smart contracts. Smart contract is actually a term used to describe computer program code that executes the performance of an agreement by using Blockchain Technology. 

This video will help you to know about the Solidity programming and Ethereum Virtual Machine. Solidity is actually high level object-oriented language for writing smart contracts.

There are two main components behind the working of smart contracts.

• Smart contract code
• Smart legal contract

This video will explain you the working of smart contracts with these two components.

ICOs have become the popular way to fund cryptocurrency projects. In this lecture, you'll understand the definition of ICOs.

In this lecture, I'll explain you the step by step guide to launch an Initial Coin Offerings. This video will help you to understand the working of an Initial Coin Offerings.

In this lecture, you'll understand the fundamentals of DAO. DAO is known as the Decentralised Autonomous Organisations running on Blockchain Technology.

In this video, you'll learn the typical structure of Decentralised Autonomous Organisations(DAOs) and the working of these blockchain based DAOs.

This video will clear all the security aspects of Decentralised Autonomous Organisations like what are the security benefits and security issues.

In this lecture, you'll learn the launching of first Ethereum Blockchain Consortium which we'll use to deploy Ethereum Blockchain based Applications.

This is the second part of the previous video in which we setup nodes. We've done the deployment in the previous video and in this video, we'll see how we can access the everything after the deployment.

In this lecture, we'll teach you to setup a wallet and a account using the chrome extension in which we've done some testing. 

In this lecture, we'll setup a development environment in which we'll download Mist wallet and see how this works. 

In this video, we'll jump into the Ethereum development by checking out the first smart contract written in the solidity programming language.

In this video, you'll learn what is the structure to write smart contracts and what is the normal way to write your first smart contract in solidity programming.

In this video, we'll teach the method of creating completely new cryptocurrency on top of the Ethereum Blockchain using solidity programming language.

In this lecture, we'll give you a demonstration by creating a new TCoin. To generate this coin, you need to deploy smart contract. You must have Mist wallet downloaded in your own machine which you can directly install form Ethereum Platform.

In this lecture, we are extending the stage one "cryptocurrency smart contracts" to stage 2 and start adding the multiple features. 

In this lecture, we'll try to improve the transfer function by putting some checks before we execute the transfer.

In this lecture, we will add an event or a login method so that whenever a transfer occurs, we should be able to notify the clients that this particular transfer has occurred.

In this video, we will try to add a feature where we should allow the sender to spend the TCoins on someone else's behalf.

In this lecture, you will be able to understand the process to execute the smart contract or the cryptocurrency which we just created in the previous lecture.

In this lecture video, let's extend the Stage 2 smart contract or cryptocurrency into the third stage where you'll understand how to add the multiple centralised feature like central administrator.

In this lecture video, we'll allow the central administrator to mint the new coins so that he can execute a function and allocate certain amount of Tcoins into any address account.

In this lecture video, you'll understand how to add a freeze or unfreeze feature as per your requirements into the existing advance TCoin of Stage 3.

In this lecture, you'll understand how to add a buy and sell feature in our cryptocurrency or the TCoin.

You might be aware that we always need a gas to transfer the token to one account to other account. In this lecture, we'll teach you how to add auto refill feature in your smart contract.

In this lecture, you'll understand the concept of cryptocurrency mining. Whenever the new blocks are mined, the person who mined the new blocks must get a new TCoin in his balance.

In this lecture, we'll test and execute the smart contract or a cryptocurrency TCoin.

In this lecture, you'll learn about the Multichain. We'll teach you what exactly is Multichain and Ho wit works?

In this lecture, we'll explain you the Compatibility & Diffrerences between the Bitcoin Core and Multichain and why it is good and bad/

In this video, you'll learn to create a Blockchain on AWS using EC2 server on Ubuntu.

In this lecture, we are connecting to a Blockchain which we initialise in Node-1 from the Node-2. In that case, we need to launch a second server and install the Multichain on that new server.

In this lecture, we'll explore some commands in the interactive mode from the Multichain.

In this lecture, you are going to understanding how to use native assets and transfer them to one node to another node without interacting with the Blockchain.

In this lecture, we will work with Multichain Streams which is very amazing concept to enable everyone to look at the Blockchain as a key value pair database.

In this lecture, you'll be able to start the mining by enabling the Node-2. 

This lecture will give you an understanding of how to install the Multichain Explorer. It is almost like a Bitcoin Blockchain Explorer.

In this lecture, we'll be seeing Multichain Web Demo, how to install it and how to use it. Multichain Web Demo is an interface in which you can actually perform the transactions. 

In this lecture, you will understand the architecture of applications and how the whole flow will work in these applications.

In this lecture. we'll setup the development environment in which we'll download Ethereum Mist wallet from Ethereum platform.

In this lecture, we'll be installing a Multichain on our Ubuntu server that we just installed and launched on AWS machine.

In this lecture, we'll create Web API which will publish the data to the private blockchain which we have created in the previous lecture.

This is the second part of the previous video. In this lecture, we'll be creating the API's for the publishing and retrieving the data.

In this lecture, you'll understand how to upload the signature of the file using the API's via web interface.

In this lecture, we'll check the PoE that we have generated recently in the backend or in the Multichain interface or command like interface

In this video, we'll show you how to verify the particular proof of existence using the web interface.

In this lecture, you'll understand what is Hyperledger. Hyperledger is an open source collaborative effort created to advance cross industry Blockchain Technologies.

In this lecture, you'll understand what is Hyperledger Fabric under the Hyperledger technology. Hyperledger Fabric is an open source Blockchain framework implementation hosted under Hyperledger project.

In this lecture, we'll compare the Hyperledger fabric technology with the other technologies. This videos also contains some useful comparison charts.

In this lecture, you'll understand the architecture of Hyperledger Fabric.

In this video, you'll learn about the components of Hyperledger Fabric.

In this lecture, we'll talk about the advantages of Hyperledger Fabric like:

• It is a Decentralised Permissioned Network.
• All users will have Identity.
• Data protection policy can be enforced.

In this lecture, you'll understand the working of Hyperledger through a single Application flow.

In this lecture, you'll be able to start your own Blockchain using IBM Bluemix platform.

This lecture will show you the interface of IBM Bluemix Blockchain services.

In this lecture, we'll show you how to deploy the demo chain code in IBM Bluemix Blockchain and start interacting with it.
