Why Is Everyone Talking About Blockchain Technology?

Blockchain technology is the talk of the town. This is due to the fascinating features it offers as well as the timely answers it provides to a variety of organizations, both offline and online. Blockchain technology is a huge part of the digital world, and it's just getting bigger every day as new features are introduced. In this article, we are going to understand what Blockchain actually is, its origin, components, as well as its pros and cons to analyze why everyone is talking about this innovative technology. So, without further ado, let’s dive into it!

What is Blockchain?

In simple terms, the Blockchain is a decentralized, public, and unchangeable database that enables real-time transaction processing and tracking across a network of enterprises. The application of Blockchain technology is not restricted to monetary transactions and cryptocurrency only; in fact, it can also be used to track actual assets. For instance, real estate, automobiles, insurance, and several other commodities can all be tracked using Blockchain. Most importantly, it also enables you to track intangible assets such as copyrights, voting records, certifications, patents, and trademarks while retaining their accuracy and legitimacy.

Technically, the term "Blockchain" refers to an immutable database that is distributed across a network of computers. All the data sent over the network is organized into blocks, which store the data until they are completely full. When a block is full, it is closed and linked to the next block that stores the upcoming data, and this process keeps on going to store new information in the Blockchain. From the very first to the very last block, the blocks are linked together like a chain. The beauty of Blockchain technology is that it allows a transaction/record to be added to the database only after the consensus of all the nodes in the network, and once it’s in the database, it cannot be altered.

Origin of Blockchain

Blockchain technology has been around since the 1990s. It came into existence when two cryptographers named Stuart Haber and W. Scott Stornetta worked together on a cryptographic chain of blocks. The main purpose behind this development was to safeguard documents and timestamps in such a way that no one could edit or tamper with them. Scott and Stuart modified their project over time and included additional features that improved its efficiency, and also allowed a single block to hold more information.

However, at that time, Blockchain did not have the same level of acceptance or adoption as it does now. Up next, Blockchain development took a giant leap in 2004 when a computer scientist and cryptographic artist introduced a mechanism to enable cryptocurrency users to verify the transaction of tokens in real-time. He named this system “Reusable Proof of Work”. This mechanism triggered Satoshi Nakamoto to conceptualize the theory of distributed Blockchains in 2008 when he developed the Bitcoin whitepaper. He made notable improvements to the Blockchain infrastructure and enabled additional blocks to be added to the chain without the need of a trusted third party like Central Banks to validate the blocks.

Components of Blockchain

Blockchain comprises several components; these components include:

  1. Node

  2. Ledger

  3. Wallet

  4. Nonce

  5. Hash

1. Node:

The nodes are a critical component of a Blockchain as they store, spread, and preserve the Blockchain data. Nodes are divided into two categories – the full node and the lightweight node. Both types of nodes have their distinct functions on a Blockchain network. The full node keeps a full copy of the transactions that occur on the Blockchain and has the authority to either accept or reject any transaction. The lightweight node, on the other hand, does not have access to maintain the whole copy of the ledger. It only has access to the hash value of the transaction. That’s also why the full node uses high storage and high computational power on its end, while a lightweight node uses lesser storage and lower computational power.

2. Ledger:

The ledger is a publicly displayed database through which data is added and updated in real-time via the consensus of the different nodes running the software in the network. In a Blockchain, there are three basic types of the ledger – decentralized ledger, Public ledger, and distributed ledger. That is why Blockchain can also be referred to as a distributed, public, or decentralized ledger technology. Here is the what each ledger does:

  • Decentralized Ledger: A decentralized ledger allows every node to participate in transactions validations.

  • Public Ledger: A public ledger is accessible by anyone within the network to add information.

  • Distributed Ledger: A distributed ledger distributes a copy of the ledger to each node in the network.

3. Wallet

A Blockchain wallet allows users to send, receive, store, and exchange digital assets while giving them full control over their funds. The wallet provides users with two types of address or keys – Private keys and Public keys. Private keys are expected to be kept from any third party because it gives people access to the assets. On the other hand, public keys are used just like an account number to receive funds from a third party. A wallet also enables the users to monitor and manage the value of their assets on the Blockchain.

4. Nonce

A nonce is an abbreviation for “number only used once”. Basically, it is a cryptography number used to protect private communications by preventing replay attacks or double-spend. It is a random or pseudo-random number that authentication protocols attach to communications. It changes over time, and it usually contains a timestamp to intensify the fleeting nature of communications.

5. Hash

A hash is a function that meets the encrypted demands needed to solve a Blockchain computational process. The length of the hash does not change regardless of the file size. The hash can be used to verify the integrity of messages as well as the authenticity of the information.

Blockchain: Pros and Cons

Let’s take a look at the pros and cons of Blockchain technology to understand why it’s gaining popularity.

Pros:

  • Blockchain provides a trustworthy, secure, and verifiable platform for easy and speedy business transactions at a minimal cost.

  • It ousts middlemen like lawyers, central banks, and accountants from verifying transactions, and it reduces paperwork.

  • It gives users complete control over their assets and data. Thus, it provides complete anonymity and privacy to users that no platform could offer.

  • Blockchain offers a top level of security that prevents its information from being altered or changed. This ensures that every user operates in a secure environment by limiting fraudulent activities and unauthorized actions.

Cons:

  • The most common issue that users face while utilizing Blockchain is scalability. Blockchain networks can be congested with too many activities or transactions, which may lead to a slow process of transactions.

  • The maintenance of Blockchain requires a lot of energy and resources like electricity, active data connection, computational power, etc.

  • The Blockchain is immutable, meaning once a transaction has been signed and validated, it can never be reversed again. As we know, mistakes can occur sometimes, and if they do, there is no way to fix them in Blockchain. This can make users lose a huge amount of assets or property in case of an error. There have been several issues like this in the past.

Why Is Everyone Talking About the Blockchain?

Blockchain is one of the most powerful technological forces, attracting individuals and businesses from all walks of life. In fact, the majority of the banks in the United States and Europe are studying the possibility of adopting Blockchain and analyzing its potential to help them run their businesses more efficiently. According to reports, financial institutions alone have spent $552 million on Blockchain-Powered projects in 2022. What’s more, it's expected that businesses will spend up to $20 billion per year on Blockchain technical services by the end of 2024.

All this makes you wonder why everyone is interested in the Blockchain? Well, it’s all thanks to its versatility and wide range of applications in almost all sectors, including cryptocurrency, electronic voting, decentralized storage, identity verification, medical, agriculture, shipping, supply chain, etc. Blockchain has revolutionized every industry it has touched and brought the best out of it.
