As blockchain grows and becomes more user-friendly, you have the responsibility of learning this advanced technology for future preparedness. If you 're new to blockchain, it' s the right platform to get solid basic knowledge. In this article, you will learn how to answer this question, what is blockchain technology? you will also learn how blockchain works, why it is important, and how you can use this field to pursue your career.

What is Blockchain :- 

Blockchain technology is a structure that stores records of public transactions in multiple databases, also known as blocks, into a network connected through peer-to-peer nodes. Typically, this storage is called a digital ladger.

Each transaction in this laser is authorized by the owner's digital signature, which authenticates the transaction and protects it from tampering. Therefore, the information contained in the digital laser is highly secure.

In simple terms, digital ladgers are similar to Google spreadsheets shared between multiple computers in a network, in which transaction records are stored based on actual purchases. The attractive angle is that anyone can see the data, but they cannot corrupt it.

Types of Blockchain -

There are four different types of Blockchains. They are as follows :-

1. Private Blockchain Networks :-

A private blockchain is managed by a network administrator and participants require consent to join the network. There are one or more entities that control the network and this leads to a dependency on a third party for the transaction. In such blockchain, only the entity participating in the transaction is aware of the transaction made, while others will not be able to access it.

Some of the features of private blockchain are:

Full Privacy -

It focuses on privacy concerns.

Private blockchains are more centralised.

High efficiency and fast transactions -

When you distribute the nodes locally, but there are very few nodes to participate in the laser, the performance is faster.

Better scalability -

Being able to connect nodes and services on demand can give a big benefit to the enterprise.

2. Public Blockchain Network :-

Public blockchains are open networks that allow anyone to participate in the network, i.e., public blockchains without permission. In this type of blockchain, anyone can connect to the network and read, write or participate within the blockchain. A public blockchain is decentralized and does not have a single unit that controls the network. Data on public blockchain is safe because it is not possible to modify or modify the data after it is validated on the blockchain.

Some of the public blockchain features are:

High-security

It is safe because of mining (51% rule).

Open-environment

The public blockchain is open for all.

Anonymous nature

Everyone in the public blockchain is anonymous. There is no need to use your real name, or real identity, so everything will be hidden, and based on that no one can track you.

There are no rules

There is no rule of public blockchain which nodes have to follow. So, there is no limit to using this platform for your betterment

Absolute transparency

The public blockchain allows you to view the balance sheet at any time. There is no scope for any corruption or any discrepancy and everyone has to maintain the balance sheet and participate in the consensus.

Actual decentralization

This type of blockchain has no centralized unit. Thus, the responsibility of maintaining the network is entirely on the nodes. They are updating the laser, and it promotes fairness with the help of unanimous algorithms.

Full User Authorization -

Typically, the user in any network has to follow a lot of rules and regulations. In many cases, the rules may not even be reasonable. But not in the public blockchain network. Here, all the users are empowered as there is no central authority to look into their every move.

Irreversible

When something is written to a blockchain, it cannot be changed.

Distributed

Databases are not centralized like client-server approaches, and all nodes of blockchain participate in transaction verification.

How Does Blockchain Work?

There are three types of Blockchain. They are :-

Blockchain consist of three main concept Blocks, Miner, Nodes .

Blocks :-

The Data in blocks.

A 32 - bit integer called nonce. When a block is created, non-randomly generated, which then generates the block header hash.

Hash is a 256-bit number that is non-connected. It must start with a large number of zeros.

When the first block of a series is created, a non-cryptographic hash is generated. The data in the block is considered signed and is permanently non-connected to the hash until it is mined.

Miner :-

The miners form new blocks on the chain through a process called mining.

Each block in a blockchain has its own unique non and hash, but it also refers to the hash of the previous block in the chain, so mining the block is not easy, especially on large chains.

Miners use special software to solve an incredibly complex mathematical problem of finding a non that generates an accepted hash. Because the non is only 32 bits and the hash is 256, there are about four billion potential non- hash combinations that must be mined before they are found to be correct. When this happens, the miners are said to have got the "golden non" and their blocks are added to the chain.

To change any block first in the series not only the block with the change, but all the blocks that come later need to be re-mined. That is why blockchain technology is extremely difficult to manipulate. Think of this as security in mathematics, because finding a Golden Non requires a lot of time and computing power.

When a block is successfully mined, the change is accepted by all the nodes on the network and the miner is rewarded financially.

Nodes :-

Decentralization is one of the most important concepts in blockchain technology. No computer or organization can own the chain. Instead, it has a distributed account book through the nodes connected to the series. Nodes can be any type of electronic device that maintains copies of blockchain and keeps the network functional.

Each node has its own copy of the blockchain and the network must algorithmically approve any new mining block to update, authenticate and validate the chain. Since blockchains are transparent, each action in the ledger can be easily checked and viewed. Each participant is given a unique alphanumeric identification number which indicates their transaction.

Combining public information with a system of check-and-balance helps to maintain the integrity of the blockchain and creates confidence among users. Essentially, blockchain can be considered as a measure of trust through technology.
