How Do Blockchains Work?
A peer-to-peer network of nodes that all communicate with one another is a blockchain. These nodes are simply computers that perform tasks similar to those of web servers, such as managing software and storing data that is accessible whenever a user is connected to the blockchain. Everyone can join to the public network that is created by all the nodes working together.

A blockchain can be conceptualized in various ways:

 

One enormous global computer made up of interconnected smaller computers (nodes).

Anybody can join to a network to send money, execute programs, etc.

a database that enables the storage and retrieval of data.

Blockchains take on duties often performed by web servers, including:

 

executing program code

organizing a database

Blockchains operate differently from conventional web servers, though. The entire blockchain’s code and data are decentralized, or dispersed across all of the network’s nodes. It is not hosted by a main web server.

 

The public ledger is made up of blocks, which are chains of entries containing all of this information. The network as a whole works to maintain the security and integrity of this data. That is what gives the blockchain its incredible power!

 

So how do you access and use blockchain?

 

You can either operate your own node or connect to one because it’s a network of nodes. When you do, you’ll have access to the blockchain’s entire potential!

 

How Do Smart Contracts Work?

The basic blocks of smart contracts are what we utilize to develop blockchain apps. We can create these apps using source code and upload them to the blockchain. The computer language Solidity, which I will teach you in this tutorial, is used to create them.

 

Since smart contracts are immutable, they cannot be altered once they have been created. A smart contract’s code cannot be modified like a regular program once it has been posted to a blockchain. This is due to the fact that it stands for a digital contract or agreement. You wouldn’t want a real-world contract to change after it is created, after all.

 

A smart contract can be compared to an online microservice or API. A smart contract is the layer that reads, writes, and executes business logic if the public ledger is analogous to a database.

 

How Do Smart Contracts Operate?

In this tutorial, we’ll construct smart contracts to drive the market. It will operate somewhat similarly to a vending machine.

The Ethereum coin will be sent to the smart contract whenever someone purchases a product in the marketplace. Similar to a vending machine, the smart contract will dispense the product to the buyer and quickly transmit the bitcoin payment to the seller.

 

How Do Blockchain Apps Operate?

Let’s first examine how a typical web application functions in order to comprehend how a blockchain application functions.

 

Diagram of a Web Application

You typically use your web browser to access a web page with a web application. This website’s whole HTML, CSS, and JavaScript code is housed on a single web server, which communicates with a backend (created in any programming language) and a database.

 

Different principles govern how the blockchain application we’ll design in this lesson functions.

 

App Diagram for Blockchain

Using a unique web browser that communicates with a front end website created in HTML, CSS, and JavaScript, we will access our blockchain application. This website will communicate directly with the blockchain rather than a backend web server. The blockchain will serve as our decentralized marketplace’s backend, hosting all of the code and data.

 

After going through the fundamentals, let’s begin developing our project.
