What Is Blockchain Technology In Cryptocurrency?

You have likely heard the phrase “blockchain technology” about cryptocurrencies like Bitcoin over the past few years. You might be wondering: “What exactly is blockchain technology?” As there is no concrete meaning that the average person can readily understand, Blockchain appears to be a platitude, but only in a hypothetical sense.

What Is Blockchain Technology In Cryptocurrency 1

It is essential to explain “what blockchain technology is,” including the technology involved, how it functions, and how it is becoming important in the digital sphere.

You are responsible for educating yourself on this developing technology so that you are ready for the future when Blockchain develops and becomes more approachable. If you’re new to Blockchain, this is the best location to learn the basics.

In this post, you may find out how to respond to the query “what is blockchain technology?”. Additionally, you will discover how blockchain functions, why it’s significant, and how you may use this area of study to advance your profession.

Let’s begin by quickly defining basic terms. The technology that makes cryptocurrencies possible is called Blockchain (among other things). The most well-known cryptocurrency, for which blockchain technology was created, goes by the name of Bitcoin.

Similar to the US dollar, a cryptocurrency is a medium of exchange. However, cryptocurrencies are digital, and they utilize encryption to manage the generation of new units of money and to confirm the movement of funds.

What Is Blockchain Technology?

Blockchain is a technique for storing data that makes it difficult or impossible for the system to be altered, hacked, or otherwise abused. A blockchain is a distributed ledger that distributes and copies transactions among a network of computers.

Blockchain technology (sometimes called “blocks”) is a platform for storing public business records across multiple databases in a network connected by peer-to-peer nodes. This type of storage is frequently referred to as a “digital ledger.”

What Is Blockchain Technology

Every transaction in this ledger is validated and protected against fraud by the owner’s digital signature, which also serves to authenticate the transaction. As a result, the data in the digital ledger is quite safe.

The digital ledger can be described as a network of computers sharing a Google spreadsheet where transactional data are kept according to actual purchases. The intriguing aspect is that while everyone may view the data, it cannot be altered.

Why Is Blockchain Popular?

Consider sending money from your bank account to your relatives or friends. Using their account number, you connect to online banking and transfer the funds to the other individual. Your bank updates the transaction records after the transaction is complete. It seems to be fairly easy, right? A potential problem exists, but most of us ignore it.

These kinds of transactions are easily manipulated. People aware of this truth are frequently reluctant to use these kinds of transactions, which is why third-party payment programs have developed over the past few years.

But the main motivation behind the development of Blockchain technology was this weakness. In terms of technology, Blockchain is a digital ledger that has recently attracted much interest. But why has it gained such a following? So let’s investigate it to understand the idea fully.

Why Is Blockchain Popular

Data and transaction recording is an essential components of the business. When this data is handled internally or provided through a third party, such as brokers, bankers, or lawyers, it costs the business time, money, or both. Fortunately, Blockchain eliminates this drawn-out procedure and enables the transaction to move more quickly, saving time and money.

Most people believe Bitcoin and Blockchain may be used interchangeably, but that is not the case. However, Bitcoin is a currency that depends on Blockchain technology to be secure. Blockchain technology can enable applications connected to multiple industries like finance, supply chain, manufacturing, etc.

How Does Blockchain Technology Work?

You may have observed that several companies have been incorporating Blockchain technology in recent years. But how does Blockchain technology operate? Is this a substantial modification or merely an addition? Let’s start with demystifying Blockchain technology since it is still in its infancy and has the potential to be revolutionary in the future.

Combining three popular technologies, Blockchain:

  • Keys for cryptography
  • A network of peers with a common ledger
  • A method of computing that can be used to store network transactions and records

Two keys make up a cryptography key: private and public keys. These secrets aid in the execution of successful transactions involving two parties. Each person has a unique set of these two keys, used to make a secure digital authenticity reference.

This protected identification is the most important part of Blockchain technology. In the world of cryptocurrencies, this identity is called a “digital signature,” It is used to approve and keep track of transactions.

The peer-to-peer network and the digital signature are combined; many people who serve as authorities use the digital signature to agree on transactions and other matters. As soon as they approve a transaction, it is mathematically verified to ensure that it is valid.

Which leads to a successful secured transaction between the two network-connected parties. In conclusion, cryptography keys are used by Blockchain users to conduct various kinds of digital exchanges across the peer-to-peer network.

History Of Blockchain

Satoshi Nakamoto, whose real name is still unknown, created bitcoins in 2008. originally proposed the idea of blockchains. Nakamoto used a technique similar to Hashcash as the architecture continued to advance and change. It ultimately evolved into bitcoin’s core, a well-known cryptocurrency that acts as a public record for all network transactions.

Over time, the Bitcoin blockchain files, which held all of the network’s transactions and other data, got much bigger. It had 20 gigabytes by August 2014, and by the beginning of 2020, it had exceeded 200 gigabytes.

Advantages And Disadvantages Of Blockchain

Blockchain technology has several benefits and drawbacks to take into account.


Blockchains can protect and secure sensitive data from online transactions thanks to their high level of security, which is one of their main advantages. Blockchain technology also provides quick and convenient transactions for those who desire them.

In contrast to other transaction techniques, which can take several days to complete, it only takes a few minutes. Additionally, there is no third-party involvement from governmental or financial entities, which many users view as a positive.


Public and private keys are used in cryptography and Blockchain; reportedly, private keys have caused issues. One drawback of blockchains is that users face several difficulties if they misplace their private keys. Another drawback is the scaling limitations resulting from the cap on transactions per node.

As a result, completing many transactions and other chores can take several hours. Another important drawback of Blockchain is that information can be hard to add or change once it has been recorded.

Types Of Blockchain

Blockchains come in four different varieties. These are what they are:

Networks Of Private Blockchains

On closed networks, private blockchains function well for private corporations and organizations. Private blockchains allow businesses to set network characteristics, accessibility and permission choices, and other crucial security features. A single authority controls a private blockchain network.

Public Blockchain Networks

Public blockchains, the source of Bitcoin and other cryptocurrencies, also helped spread awareness of distributed ledger technology (DLT). Public blockchains also aid in removing some difficulties and problems, including centralization and security weaknesses.

Instead of being kept in one place, data is spread throughout a peer-to-peer network using DLT. A consensus algorithm verifies the legitimacy of information; proof of stake (PoS) and proof of work (PoW) are two popular consensus techniques.

Permissioned Blockchain Networks

Permissioned blockchain networks, sometimes called hybrid blockchains, are private blockchains that grant approved users exclusive access. These kinds of blockchains are frequently set up by businesses to achieve the best of both worlds. They provide better structure when determining who can join the network and in what transactions.

Consortium Blockchains

Consortial blockchains have both public and private components, similar to permissioned blockchains. However, a single collaboration blockchain network will be run by several different businesses. Though initially more difficult to set up, these blockchains can provide superior security once operational. Consortia blockchains are also the best for working with various organizations.
