What Is Blockchain And How Does It Work?

Over the past few years, the Internet has shown immense opportunities to grow, and we are in the direction that will shape the Internet forever. One thing that always worries us is security concerns.

That also has reduced since blockchain technology came into play. 

There are high chances that you hear the term blockchain technology but have yet to figure out what it is and how it works. 

We understand your concern and always try to resolve your query in various ways. 

This technology will stay here forever. The onus is on us to learn about it and prepare for the future.

For those, who are new to this term, I want to assure you that you have landed in the right place.

We will tell you all the inside-outs of blockchain technology. 

What is blockchain technology?

Blockchain, in the simplest way, is a method of recording transactions, which makes it impossible to hack, change or manipulate anyone.

A blockchain is also known as Distributed Ledger Technology (DLT) because it distributes the transactions across a network of systems participating in the blockchains. 

Once the transaction enters the blockchain, it becomes impossible to alter, edit, or rectify the error.

If you want to correct an error, you need to create another transaction to correct the previous one, and both transactions will appear simultaneously.

All transactions occurring in the ledger are authorized via the digital signature of the owner, which authenticates the transaction and safeguards it from tampering.

This authentication makes the transaction in the blockchain highly secure. 

How does blockchain work?

Blockchain allows digital transactions to be recorded and distributed but not edited. It is next to impossible to hack, alter or manipulate transactions once they entered into blockchain technology.

That's why blockchain is an immutable ledger that prevents transactions from being hacked or changed. 

● Once the transaction occurs, it records in the "block" of data. This transaction shows the movement of the digital asset, which could be tangible or intangible. 

● Each of these blocks connects to the previous or next block and creates a chain of blocks as the asset moves from one place to another. These blocks confirm the sequence and exact time of transactions, which prevent other blocks to alter or insert in between two existing blocks.

● All the transactions are blocked together in an irreversible chain every addition to the existing block strengthens the previous block, consequently, the entire blockchain. 

Every blockchain consists of three main concepts: blocks, nodes, and miners. 

Block

A block in the blockchain is a place where all the information is stored and encrypted. Every block has three components, such as data, nonce and hash. 

● Data: Data is all the information stored in the block.

● Nonce: A nonce is a whole number used only once and generated randomly when the block is createdAtAt. 

● Hash: It is a number that is permanently attached to the nonce. 

In other words, we could conclude these in a way like the first block of the chain is createdAtAt when the nonce generates the cryptographic hash.

The data stored in the blocks believe to be authorised and tied forever with the nonce and hash unless it is mined. 

Nodes

Blockchain nodes are network stakeholders authorized to keep track of all the transactions in distributed ledgers and serve as communication hubs for various network tasks. 

The primary job of nodes is to check the legality of all transactions in blockchain technology.

After that, allocate the unique identifier to each node that helps to distinguish one node from other nodes easily.

Miner

Miners are responsible for the creation of new blocks on the chain through a process called mining.

Every block in the blockchain has its own unique nonce and hash.

It also references the hash of the previous block in the chain, which makes this mining task very complicated, especially on large chains. 

Closing Thoughts

Blockchain technology is going to change the way internet security works. Web3 developers need to understand the importance of learning and the real-world application of blockchain technology.

The future lies in blockchain, crypto, and metaverse kind of things. Ignoring them right now is definitely a mistake that you need to avoid.
