The Complete is here! Practical Guide to Blockchain Application Development

If you were to ask me what Information Technology Domain is going to make the future better, I would answer it without any hesitation: its block chain-based decentralized applications as well as smart contracts.

Blockchain is simply a transaction leadger that stores identical copies of transactions across all computers within a network. It is important to note that once information has been placed in a block of the blockchain block chain, it cannot be altered or tampered with.

Blockchain research and development has been a major focus of financial and government organizations. Most of these institutions have implemented blockchain in their financial services and record-keeping.

Blockchain-based smart contracts can also replace traditional paper contracts and other promissory documents. Smart Contract is an electronic contract which can be executed by itself once the conditions in the contact are met.-filled. Because it is also based on blockchain, once it has been created, it can’t be altered by anyone.

This is the perfect time to learn about blockchain’s practical implementation if you are a tech enthusiast or programmer.

There are many books and material that explain block chain concepts. However, only a small number of books and materials explain how it can be applied.

I have tried to maintain a balance of the practical application and the theoretical concepts in this course.

You will be able to understand how block chain can be implemented in both your existing and future software projects.

Here is a list of topics that I included in this course.

Before we move on to the practical sessions intensely, we will have a few secessions where we discuss the history of smart contracts and block chain distributed apps.

Session 1 will cover the history of block chains and distributed applications. We will also examine the basic structure and functions of a block. Which is the block building block of the block-chain, which is a series of these blocks.

Session 2 will cover the basics of how blocks are linked to create a block chain. We’ll also discuss the security features that make blockchain so secure.

Session 3 will be a discussion on the different types of networks as well as the concept of cryptocurrency currencies such bitcoin, which are built on blockchain technology.

We will be discussing smart contracts based upon blockchain in session 4. We will also discuss the many applications of blockchain in the present and the future.

After we have a basic understanding of the concepts, we’ll jump straight into our first practical Blokchain workshop. We will create a working model for a conceptual blockchain using JavaScript and a JavaScript runtime called Nodejs. Even if you don’t have any JavaScript knowledge, I’ll explain everything clearly enough for even the most novice JavaScript user to understand.

In session 5, we’ll prepare our computer by configuring and installing nodeJS and visualstudio code. This will enable us to create the JavaScript Blockchain.

Sessions 6 will allow us to create the class for one block. This block will then be used to make the block chain.

Session 7 will see us create the first block of the chain, called the genesis block.

8. Session: We’ll learn how to add new blocks and create the rest of the blocks.

Session 9: We will test the block-adding mechanism in our JavaScript blockchain.

We will also implement hash verification in session 10. This is the most important security measure within our blockchain.

We will add an additional security measure, called proof of work, to stop quick tampering attempts on our JavaScript block chains.

Session 12 will introduce the concept of mining reward for minors who mine and validate new blocks in our JavaScript block chain.

This is all for our JavaScript conceptual blockchain app. From the next session onwards, we will get down to business using the actual Ethereum block chain network. In the following sessions, we’ll create an Ethereum-based blockchain as well as deploy our smart contracts within the ethereum network. For your information, ethereum (or ethereum) is the most popular open-source public blockchain system in the world.

In session 13, we will prepare our systems for building our ethereum blockchain by downloading and installing dependencies such as nodejs and ganache, metamask concrete language, truffle framework, sublime text editor and sublime text editor.

We will set up these dependencies in session 14. Then, we will run a basic test to ensure everything is ready for development.

Our blockchain smart contract project will be built using solidity, ethereum and we will continue to build it. This is a contest application to find the best actor. It has two contestants, Tom and Jerry. To find out who has the most viewers support, we will need to create a block-chain-based app.

We will create the model for the contestants in the next session 15 and include Tom and Jerry as contestants.

Session 16 will be used to fetch the contestant list with web3js. This is the library that interacts with the blockchain.

Because smart contracts can only ever be created once and cannot change, it is important to test the code before you deploy it in the blockchain network. The only way to fix a bug or omission is to delete the contract and create a new one. This can be very tedious and time-consuming. In session 17, the blockchain will be tested using the truffle framework’s testing environment, which simulates the transaction of creating users.

Block chain interaction was done over the command line interfaces node js and truffle framework. It’s time for it to be made visible to our customers.-Line users are presented with a web-based front end that is attractive and user-friendly. This page uses a web page. To proceed, we will create session 18 the html section of the front end application and session 19 the JavaScript portion of the beautiful and simple HTML page. We will then list the contestants in the best actor contest to public by running lite-Server that comes with the truffle framework

Session 20 will see us add voting functionality to our blockchain smart contracts.

We need to verify that the rules and conditions we have implemented in the smart contracts are correct for all members and non-members of the network. In session 21, we will use the truffle framework testing method to test the functionality.

Session 22 will have rules and restrictions about our best actor contest. Rules such as, users can only vote once and they cannot vote for non-existing contestants.

The command line is the only way to vote. In session 22, we will add the ability to cast votes to any contestant via our web interface.

We will also create an event watch in the final session. It will listen out for the event of voting. Once the voting is done, it will refresh your page and fetch data on the blockchain network. This will allow you to know the winner of this contest every now and then.

Although these are only samples, they will provide enough information for you to be able to see how the blockchain could be used in your web and mobile projects. You will be able to stay ahead of the others in this race for blockchain technology.

We will issue a certificate of completion to you after your successful completion of this course. This will be a valuable asset in your career as a software developer, software engineer, or software architect.

Let’s get to the future of technology with blockchain. We look forward to seeing you in the classroom. We wish you happy learning.
