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 blockchain-based decentralized applications and smart contracts. Put simply, blockchain is a transaction ledger that maintains identical copies across each member computer within a network. 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.

Since it’s also based in blockchain, once created, it cannot be tampered by anyone. 

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

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

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

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 until 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 nonexisting contestants.

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

So let’s jump into the future of technology using blockchain. See you soon in the classroom. Wishing you a happy learning.
