Hello and welcome to The Complete Practical Guide To Blockchain Application DevelopmentIf you are going to ask me which is the Information Technology Domain that is going to change the future, without any doubt I would surely say its block chain based decentralized applications and smart contracts.Put simply, blockchain is a transaction ledger that maintains identical copies across each member computer within a network. The interesting feature is that, once an information is placed inside a block of the block chain, the tampering or changing of it is impossible.Governments and financial organizations have already invested millions of dollars into blockchain research and development and most of them have already implemented blockchain in financial services and record keeping.

Also blockchain based smart contracts are replacing the conventional paper contracts and other promissory deeds. Smart contract is an electronic contract that can execute itself after the conditions mentioned in the contact is full-filled. Since its also based in blockchain, once created, it cannot be tampered by anyone.

If you are a technology enthusiast or a programmer who wish to integrate blockchain in your applications, this is the right time to get yourself a thorough knowledge about the practical implementation of blockchain.

There are tons of material and books out there explains, the concepts, nuts and bolts of block chain. But only a very few of them explains how it can be practically implemented.

In this course, I have taken extreme care to keep a 30 / 70 percentage balance between the theoretical concepts and the practical implementation respectively.

After this course, you will get a clear idea of how and where to implement block chain in your existing software projects as well as your upcoming project ideas.

Here is the overview of the list of topics that I have included in this course

Before we proceed with the intense practical sessions, we will have the first few secessions in which we discuss the history and the basic concepts of block chain distributed applications and smart contracts.

In Session 1, we will discuss the history of block chain and distributed applications. Also we will check the basic structure of a block. Which is the building block of the block chain, which is a chain of these blocks.

And in session 7, we will create our first block in the chain called genesis block.

In session 8, We will and the functionality to add new blocks so that we can create rest of the blocks

In session 9, we will test the block addition mechanism in our in our JavaScript block chain

and in session 10, we will implement hash verification, which is the most important security measure inside our block chain.

In the next session 11, we will include an additional security measure called proof of work to prevent the quick tampering attempts of our JavaScript block chain.

In session 12, we will implement the concept of mining rewards for the minors who mines and validate new blocks for our JavaScript block chain.

And thats all with our simple JavaScript conceptual blockchain application and from the next session on wards we are going to get our hands dirty with some serious business using the actual ethereum block chain network. In the coming sessions, we will create an ethereum based blockchain and deploy our smart contract within the ethereum block chain network. For your information, ethereum is the worlds most popular open source public blockchain platform.

So in session 13, we will be getting our systems ready to build our ethereum block chain by downloading and installing the dependencies which include nodejs, ganache, metamask solidity language, the truffle framework and sublime text editor for coding.

In session 14, we will configure these dependencies and we will do a basic test to make sure everything is ready to proceed with the development.

we will start building our blockchain smart contract project out of solidity and ethereum. This project is a simple contest application, for finding out the best actor, with two contestants Tom and Jerry. We will have to build a block chain based app to find who is getting the maximum viewer support.

We will test the functionality till now using the truffle framework testing mechanism in session 21

In session 22, we will include rules and restrictions for our best actor contest. Rules like, a user can vote only once and the user cannot vote for any non existing contestants.

Till now the voting can only be done via a command line.

So lets jump into the future of technology using blockchain. See you soon in the class room. Wishing you a happy learning.
