What Is Blockchain? Is It a Technology or A Cryptocurrency?

Blockchain is a decentralized, immutable database that makes it easier to track assets and record transactions in a corporate network. An asset may be physical (such as a home, car, money, or land) or immaterial. On a public blockchain, practically anything of value may be recorded and traded, lowering risk and increasing efficiency for all parties. Platforms such as the are being used to trade different currencies.

Why blockchain technology matters

Information is essential to business. It is best if it is received quickly and accurately. Blockchain technology is used for providing this information because it offers real-time, it can be shared, and data that is completely visible and stored in an immutable ledger and accessible only to users who are part of a public blockchain network. An example is a blockchain may packets called production, finances, and payments. Furthermore, because everybody has an approach to the identical versions of the truth, you can view every aspect of a transaction from beginning to end, increasing your confidence and opening up new prospects.

Essential components of a blockchain

The crucial components of a blockchain are the following:

The use of distributed ledgers

The distributed ledger and its permanent record of transactions are available to all network users. Transactions are only recorded once on this shared ledger, preventing the repetition of effort present in conventional corporate networks.

Unchangeable records

Once a transaction has been added to the shared ledger, no participant is permitted to alter or interfere with it. New transactions must be added to undo an error in a transaction record.

Sensible contracts

A set of instructions known as an intelligent contract is saved on the chain and automatically carried out to speed up transactions. 

Working of blockchain

The working of blockchain is divided into the following parts:

Each transaction is documented as a “block” of data as it happens.

These transactions demonstrate the transfer of an asset, whether physical (a product) or intangible (intellectual). Whom, why, when, where, how much, and even the condition—such as the warmth of a food shipment—can all be recorded in the data block.

Every block is interconnected with those that came before and after it.

As an asset is moved from one location to another or ownership changes, these blocks create a data chain. The blocks link tightly together just to prevent any blocks from becoming altered or a block from being introduced between two existing blocks, and the blocks certify the precise timing and order of transactions.


Blockchain is currently used most frequently as the foundation of cryptocurrencies like Bitcoin or Ethereum. A blockchain keeps track of all cryptocurrency purchases, exchanges, and expenditures. The more cryptocurrency users there are, blockchain technology may become commonplace.

Cryptocurrencies are still not widely used to purchase products and services because of their volatility. The availability of digital asset services to retailers and vendors is expanding thanks to companies like PayPal, Square, and other money service organizations, says Patrick Daugherty, senior partner at Foley & Lardner and chair of the firm’s blockchain task force.

Benefits of Blockchain Increased Transaction Accuracy

This can lower errors since a blockchain transaction needs to be confirmed by several nodes. The other nodes would notice something is off and recognize the error if one server has a database error.

In contrast, if a mistake is made in a traditional relational database, it could be more likely to be approved. Additionally, each asset is uniquely identifiable and recorded on the blockchain ledger, eliminating the possibility of double spending.


Blockchain technology is still a niche technology despite its potential. Gray believes that blockchain technology has the potential to be employed in additional contexts, but that depends on future governmental regulations. It is still being determined when and whether regulators like the SEC will intervene. The objective will be to safeguard markets and investors. That much is clear, he says.

Shtylman compares blockchain to the early days of the internet. Before Google and Facebook had their first iterations, the internet had been around for nearly 15 years. Although it’s challenging to anticipate wherever blockchain technology will go in another ten or fifteen years, it will fundamentally alter how we transact and communicate with one another in the future, much like the internet.


Writing has always been a big part of who I am. I love expressing my opinions in the form of written words and even though I may not be an expert in certain topics, I believe that I can form my words in ways that make the topic understandable to others. Conatct:
