Blockchain Technology – Things You Need to Know

Blockchain technology is probably one of the most talked-about technological breakthroughs of the 21st century. In the digital era, Blockchain technology has the potential to transform every facet of the economic environment. Read this article to find out different things you need to know about Blockchain technology.

Although Blockchain was initially designed to support bitcoin, now it drives many other cryptocurrencies. More than 10,000 cryptocurrencies, such as Bitcoin, Ethereum, Cardano, Polkadot, etc., are running under Blockchain. Generally, cryptocurrencies make secure online payments using decentralized systems like Blockchain. Cryptocurrencies like Bitcoin are accepted and used in online stores, service providers, buying video games, Bitcars, digital trade, or even purchasing virtual land, often known as Metaverse

Blockchain Technology - Things You Need to Know

Developers of Blockchain are continually seeking to integrate it in several industrial sectors such as medical, educational, government, banking, and many more. With its growing popularity, many businesses and other industrial sectors have integrated Blockchain with their system as they find it more secure than other centralized databases. 

But what exactly is a Blockchain, and what are things you need to know about Blockchain technology? Let’s take a closer look.

Things you need to know about Blockchain Technology

What is Blockchain?

In contrast to conventional databases, Blockchains are open and decentralized distributed ledgers that store data in “block” linked in a “chain” using cryptography. Each block consists of its own timestamp and a link to the preceding block’s transaction data. A peer-to-peer network manages a Blockchain as a distributed ledger by communicating between nodes and verifying new blocks.

As a distributed ledger, Blockchain is used to efficiently store transactions between two entities in a transparent and permanent method using smart contracts. It is impossible to retrospectively edit a previous block’s data without altering the data in all subsequent blocks, which needs network majority agreement. So, this makes Blockchain much safer and more transparent than centralized databases.

Different types of Blockchain

Private Blockchain 

A Private Blockchain runs in a confined area, such as a private or closed network that is tied to a single business. Although it uses a peer-to-peer network and is a decentralized system like any other Blockchain, it is much smaller in a domain. Private Blockchains are typically used by a company or organization that runs on a smaller network. So, it is also known as enterprise Blockchains.

Public Blockchain

Public Blockchain is an extensive decentralized network that facilitates transactions between two parties and uses token-based algorithms. There are no restrictions and permission with the public Blockchain, and anyone with an internet connection can sign in to access public Blockchain and create a node. After accessing Blockchain, you can quickly check and verify the transaction, identify bugs, or suggest changes because of open source code. 

Hybrid Blockchain

A hybrid Blockchain is a hybrid form of a private and public Blockchain network. It uses elements of both types of Blockchain or attempts to combine the best features of both into a single system. With the hybrid Blockchain, an organization can create a private permission-based or public permission-less system, making it possible for individuals to decide who has access to the information and what information is made public.

Consortium Blockchain

A consortium Blockchain is also similar to a hybrid Blockchain which incorporates both private and public Blockchain. The only difference is that consortium Blockchain restricts the permission of its private data to a particular group. Multiple members of an organization work together on a decentralized network of consortium Blockchain. By limiting access to the network to just several members, consortium Blockchain eliminates the vulnerabilities associated with private Blockchain controlled by a single company.

How does Blockchain work?

Blockchain combines three of the major elements: cryptographic keys, peer-to-peer networks, and computer systems.

There are two types of cryptographic keys: Private key and Public Key. Cryptographic keys are necessary for a successful transaction between two parties in Blockchain. These keys are unique to each person and create a digital identity as Blockchain aims for safe identification. The safe identification refers to a “digital signature” used to authorize and verify transactions.

To summarize, Blockchain users utilize cryptographic keys to conduct various digital transactions across the peer-to-peer network. 

Is Blockchain safe?

Yes, Blockchain is entirely safe and secure. Security is the most crucial thing to know about Blockchain, and the features that make Blockchain safe are :


Cryptography secures all Blockchain transactions. As we know, Blockchain consists of a series of blocks that hold data. Each block has its hash number and link to the next block. The data stored inside the block cannot be changed, and if the hash value is changed, the block will be invalid and eventually discarded. 


Blockchain is decentralized and operates on a distributed network, so there will be no single point failure. It will prevent data corruption and prevent the system from being hacked. 


In Blockchain, all the transactions are transparent, making the data available to everyone every time. It is difficult to manipulate, change, or delete any data on Blockchain with transparency. 

What are “Smart Contracts” in Blockchain?

Smart contracts” in Blockchain are the agreements where the term of a transaction is written digitally and verified digitally with lines of computer code. In computing terms, smart contracts are a kind of program that encapsulates business logic and runs on a specialized virtual machine integrated with Blockchain or other distributed ledger.

Smart contracts are significant in Blockchain as it assists in making transactions more secure and orderly between any two parties. In addition, it facilitates the accessibility of additional components such as apps operating on different platforms.

Final words on Blockchain 

In recent years, advancement in Blockchain technology has pushed different sectors to a decentralized, trusted internet, transparency in transactions, smart contract, and a lot more. So, it’s necessary to cope with all those enhancements; it now seems essential for individuals to know different things about Blockchain. 

Blockchain has a solid potential to grow more ahead in the future. The potential Blockchain has already shown in practically every industry suggests that this is just the beginning
