What is Blockchain Technology? – A Complete Guide

If you’re wondering what blockchain technology is, it’s time to find out. In the previous era, digital technology was unheard of. But now, everyone knows the power of digital technology.

It is no different from blockchain technology. 

If you’re still in the dark, this blog will help you understand blockchain technology from start to finish and how it is revolutionizing industries today. 

We’ll also tell you about the key players driving its growth and the excellent use cases for blockchain technology coming up in the future. So, let’s get started!

Blockchain technology: an overview

Blockchain technology is a digital trust stack revolutionizing how we exchange value and information over the internet. First introduced in 1991 by Stuart Haber and Wakefield Scott Stornetta, Blockchain is a distributed ledger technology that uses a peer-to-peer network to record transactions across different nodes.

In Blockchain, records of financial transactions are saved on a digital ledger distributed among the network of computers. Each transaction forms a block of data of unique hash value

The distributed ledger technology makes it possible for any party to tamper with the record of the transaction by involving all the network participants.

Blockchain technology has implications for currencies such as bitcoin, smart contracts, digital asset registries, and supply chain management. 

It has been used in many industries, including banking, finance, healthcare, record-keeping, intelligent contracts, voting, and auditing. However, blockchain technology’s capabilities are still being explored, with potential applications yet to be discovered.

Types Of Blockchain

There are four types of blockchain technology. Let’s learn more about them one by one below:

1- Public Blockchain

Public blockchains are decentralized networks of computers that allow anyone to request or validate a transaction. They are commonly used for mining and trading cryptocurrencies, such as Bitcoin, Ethereum, and Litecoin. Unlike private blockchains, public blockchains lack privacy and security features.

However, they provide the advantage of anonymity, as personal information is not linked to transactions. Either proof-of-work or proof-of-stake consensus mechanisms secure public blockchains. In addition, they can solve different types of data storage challenges, using different algorithms to ensure secure and reliable digital transactions.

2- Private Blockchain

Private blockchains are highly secure and private networks that allow organizations to customize their access and authorization preferences. In addition, they are managed by a single authority and can only be accessed by the network authority explicitly authorized users.

Companies can use private blockchains to track product supply chains, as they would not have to share confidential information with other stakeholders in the supply chain. 

Private blockchains are helpful for private businesses and organizations as they can tailor the network to suit their unique needs and requirements. Public blockchains, on the other hand, are open and accessible to everyone.

3- Blockchain hybrid

Blockchain is a distributed ledger technology introduced in 2008 as part of a bitcoin-related proposal. It has the potential to significantly reduce the cost of transactions by eliminating the need for intermediaries such as financial institutions and clearing houses.

Hybrid blockchains include elements from both: public and private blockchains, allowing companies to control ownership of specific data stored in the Blockchain while the rest of the data remains public. These types of blockchains have a combination of centralized and decentralized features.

4- Consortium Blockchain

A consortium blockchain is a blockchain network in which multiple organizations share the responsibilities of maintaining the Blockchain. 

Consortium blockchains are typically used in business, and participants must be acknowledged to submit transactions or access data in such a blockchain network.

In consortium blockchains, there is often an open- or closed-membership policy governing who can participate and use the technology. While consortium blockchains are more complex to set up than other types, they offer better security and stability. 

They are ideal for collaboration between multiple organizations that need to share data or make transactions with the transparency of a public blockchain without the liability or trust issues that may come with public blockchain technology.

Promising Blockchain Use Cases

Blockchain business ideas have the potential to disrupt several industries, but cryptocurrencies are the most widely-used blockchain application today. Here are a few Blockchain use cases:

Smart Contracts

A smart contract is a digital, programmed agreement that verifies and enforces transactions when specific terms are met. Smart contracts can be deployed and stored on blockchain networks, allowing them to be trackable and unchangeable. 

They can facilitate, verify or negotiate a contract agreement and automatically enforce obligations when the conditions are met.

Supply Chain Management

Blockchain technology can be used in delivery and logistics to track the route of food products from their origin to the point of delivery. 

With Blockchain, companies can record the origin of the materials they have purchased, allowing them to verify the authenticity of labels such as “Organic,” “Local,” and “Fair Trade.”

By using blockchain technology, supply chain management can help prevent food from contamination and ensure its safety from farm to consumer. It also helps identify any contaminated food sources and helps to identify the source of the problem.

Data Security

Blockchain technology offers a secure and resilient platform to store and process data. As a result, it can reduce transaction processing time and costs while combating double-spending attacks.

In addition, the distributed network of nodes that must reach consensus makes fraud almost impossible within the Blockchain.

Decentralized Finance

Decentralized finance, or DeFi, allows users access to features of mainstream financial services on the Blockchain, eliminating intermediaries and reducing fees. 

Decentralized finance transactions are made via peer-to-peer consensus, reducing the risk of a single third-party point of failure.

It has applications in video games, peer-to-peer energy trading, supply chain and logistics tracking, and healthcare process optimization.

Decentralized Governance

Decentralization is an integral part of blockchain technology, making it suitable for various use cases involving distributed databases. 

In particular, decentralization improves the reliability and resilience of blockchain-based systems by eliminating single points of failure. In addition, decentralization allows for real-time access, transparency, and governance between multiple parties.

Healthcare Information Management

Blockchain technology can uplift healthcare by improving data transparency, security, and privacy. For example, using Blockchain with Healthcare Technology Trends to store patients’ medical records securely can significantly improve patient care and ensure the accuracy of medical records. 

Using Blockchain, hospitals can track and store medical record data with greater accuracy, saving millions of dollars in healthcare costs each year.

Digital Voting

Digital voting systems can use blockchain technology to store votes and prevent fraud securely. By storing votes in a blockchain-based ledger, digital voting systems can ensure that the results of a vote are accurate and verifiable without manual intervention.

Such systems would provide transparency and immutability to the voting process, allowing voters to cast ballots confidently.

How is Blockchain transforming businesses?

With blockchain technology becoming a part of our daily lives, it is only a matter of time before we see Blockchain revolutionize various industries across the globe. Here are the top three ways Blockchain is transforming businesses:

Making Payments Simpler

The decentralization of blockchain technology allows for the seamless and secure transfer of funds between different parties.

Blockchain technology can lower the costs of making payments by removing the need for a third-party payment facilitator.

Reducing Fraud

By using blockchain technology to store data securely, digital voting systems can prevent fraud. You can also use blockchain technology to track and record the movement of goods and assets, which can help deter theft and financial crime.

Creating Better Records

With blockchain technology, data can be securely stored in a distributed ledger and accessed by multiple parties. This ensures that data is accurately captured and maintained, which can improve records keeping efficiency and accuracy.


Blockchain technology has the potential to radically transform the digital economy, making it more secure and efficient than previous generations of technology. 

It’s an open, distributed ledger technology that allows people to create digital records of transactions that are verified by the network rather than a central authority.

Frequently Asked Questions

Is Blockchain a company or a technology?

Blockchain technology is a technology, not a company. Blockchain is a decentralized, distributed ledger that stores the digital assets’ ownership record. It creates transparency and trust among network members by recording transactions and tracking assets in a business network.

What are the differences between public and private blockchains?

There are a few differences between public and private blockchains. Let’s find them below: 

  • Public blockchain networks are permissionless, open to all members, and used primarily for exchanging and mining cryptocurrencies.
  • Private blockchain networks are closed systems, with only one authority managing access and security parameters.
  • Private blockchains are safer than public ones.
  • Public blockchains are immutable and challenging to alter, as no single authority controls the nodes.
  • Private blockchains resemble an in-house data storage system more than public blockchains.

Should I use open-source or proprietary software for blockchain projects?

Using open-source software would help when working on blockchain projects. This allows developers to collaborate on the code and make improvements. 

In addition, public blockchains are permissionless and allow everyone to join them- meaning they’re a good option for those who want to exchange and mine cryptocurrencies.
