What is blockchain technology? Explanation of this rupture tech'

Despite what you may have heard recently about Bitcoin, blockchain companies, Ethereum blockchains, and other cryptocurrencies, many financial experts believe it is the technology underlying virtual currencies that you should be paying attention to.

According to Lule Demmissie, president of Ally Invest, “the underlying technology that most cryptocurrencies rely on – blockchain — is a disruptive technology.” “One of those transformations happens to be cryptocurrency.”

Some people feel that blockchain technology has the potential to transform practically every aspect of our lives, far beyond the influence of cryptocurrency on our financial portfolios. It's a "revolution," according to Dr. Richard Smith, executive director of the Foundation for the Study of Cycles, a nonprofit organization dedicated to investigating recurring patterns across economies and civilizations.

Even doubters of cryptocurrency recognize the value of blockchain technology. According to Chris Chen, CFP of Insight Financial Strategists in Newton, Massachusetts, blockchain is the real gem. He believes blockchain will last much longer than popular cryptocurrencies such as Bitcoin, which he describes as a "flash in the pan." “Blockchain will continue to alter the way we conduct business.”

All of this sounds fantastic, but what does it actually imply? Here's all you need to know about blockchain, as well as what a blockchain revolution and a massive blockchain adoption would entail.

What Is Blockchain technology?
Consider a blockchain as a new type of digital record-keeping.

Many cryptocurrencies, such as Bitcoin and Ethereum, are built on the blockchain technology, but its unique technique of securely recording and sharing data has applications far beyond cryptocurrency.

A distributed ledger is what a blockchain is. DLT (distributed ledger technology) permits records to be kept on several computers, or "nodes." A node can be any blockchain user, but it requires a lot of computer power to run. Within the ledger, nodes check, authorize, and store data. Traditional record-keeping methods, which store data in a central location, such as a computer server, are not applicable.

The information contributed to the ledger is organized into blocks, or groupings of data, by a blockchain. Because each block can only carry a specific amount of data, new blocks are added to the ledger on a regular basis, building a chain.

Each block has its own cryptographic “hash” that serves as a unique identification. The hash not only protects the information within the block from anyone who does not have the requisite code, but it also secures the block's position in the chain by identifying the block preceding it.

According to Vikas Agarwal, a partner in PwC's Financial Services Advisory Practice, a cryptographic hash is "a combination of numbers and letters that can be up to 64 digits long." “That's the one-of-a-kind code that allows the puzzle parts to connect.”

Information is permanent and immutable once it is added to the blockchain data and encrypted with a hash. Each node keeps track of the whole history on the blockchain data, all the way back to the beginning. One of the major benefits of blockchain is that in this situation, It wouldn't affect the information saved by other nodes if someone interfered with or hacked into one computer and changed the data for personal advantage. Because it differs from the majority, the altered record in a blockchain system may be easily identified and fixed.

“It's practically hard for someone to reverse engineer the system and figure out what all those hashes are because of the way it works,” Agarwal adds.

How Does It Work?
Here's an example of how Bitcoin transactions are verified and stored on the blockchain.

A Bitcoin is purchased by a consumer.

Bitcoin's decentralized network of nodes is used to send transaction data.

The transaction is validated by the nodes.

Following approval, the transactions are recorded with others to form a block, which is then added to the chain of transactions.

The completed block is encrypted, and the transactions are recorded  permanently on the blockchain; it cannot be erased or changed.

The blockchain of Bitcoin is open to the public, which means that everyone who holds Bitcoin may see the record of transactions. While tracing an account's identity can be difficult, the record of transactions shows which accounts are transacting on the blockchain. Any user with the necessary computing capacity can also participate as a node in authorizing and recording transactions onto the blockchain.

However, not all blockchains are open to the public. Blockchains can be structured as private ledgers, allowing the blockchain's owner to control the transaction process. A private blockchain networks may be smaller, but it is still decentralized applications among those that participate. Using the same encryption mechanisms as public blockchains, private blockchains ensure the security of any data saved within the database and to validate transactions with the maximum security.

The concept of a secure, decentralized permanent record of information has piqued attention across a variety of industries, and it could provide answers to many of today's security challenges, record-keeping methods, and data ownership difficulties.

A Future Based on Blockchain


According to Agarwal, Blockchain gives us the technology to securely move information and have near-complete assurance in knowing the validity of any piece of information you wish to safeguard.

Consider the stories of meme subjects and celebrities who made money off digital property by selling NFTs that have been circulating in recent weeks (non-fungible tokens).

NFTs allow sellers to verify the legitimacy of a digital asset because the underlying blockchain record is immutable. When you purchase an NFT, the transaction process is recorded on the blockchain system you are using and becomes a verified record of ownership. For individuals who want to be able to authenticate the authenticity of a digital piece, one the blockchain applications iis to allow digital art and collectibles to be valued similarly to their physical equivalents. In theory, this allows creators to keep their worth by earning royalties on digital art copies.

“To the rest of us who don't value such things, that could appear perplexing,” Smith says. “But what it actually demonstrates is that a digital economy can exist alongside digital property rights.” It allows you to declare, "I own and manage this portion of the digital economy," he explains.

One of the most important applications of blockchain technology for many of us may be the protection and secure transfer of personal data.

Consider what would happen if your financial data was stored on a blockchain. When you register a new account with a new financial institution or move information between institutions, a blockchain ledger could assist you swiftly and securely guarantee that the transfer or new account is accurate and valid by using information you already have recorded. “That has the potential to eliminate a lot of costs, a lot of overhead, and it might also be a fantastic method to reduce fraud,” says Agarwal.

“Every sector has some type of information that they're wanting to trade in a highly secure way,” he predicts, and blockchain technology has potential in practically every area. A voting record that is locked in and cannot be changed after the election could help a blockchain-based election. Blockchain could help businesses keep more accurate inventory records. With increased openness across goods supply chains, blockchain might potentially help customers make more informed purchasing decisions. Food providers may be able to track recalled products more efficiently with this technology, and customers may be able to avoid commodities made with abused labor practices.

Such applications demonstrate blockchain's appeal not only for security, but also for what Chen refers to as information integrity. According to Agarwal, “Blockchain has the ability to give customers additional security and comfort around that.”

Putting Money Into the Future


Businesses, governments and econoy central authority all across the world are testing and using blockchain technology, but nothing will happen overnight. It will be a long time before we reach a position where peertopeer networks of cryptocurrency blockchain will be replaced by government currency  based on central authority  blockchain networks or where medical data are added to the chain.

In the meanwhile, you can put your money behind blockchain by investing in a blockchain-based cryptocurrency like Bitcoin, albeit that isn't the only option to do so.

You may also make standard investments blockchain-ready by modifying them. Check to see whether any of your ETFs or index fund invest in companies that are developing promising blockchain technologies or implementing them in their business processes.

Blockchain ETFs are ETFs that are entirely made up of these types of bitcoin and cryptocurrencies or cryptocurrency and blockchain companies. The Siren Nasdaq Blockchain Economy Index (BLCN), which was created in 2018, has outperformed the S&P 500's overall return both year-over-year and on a three-year average. These funds don't put any of your money into blockchain investment; instead, they invest in a variety of stocks, from well-known companies like IBM to lesser-known startups like Galaxy Digital.

While this still does not guarantee a profit, it can be a safer alternative to investing directly in the notoriously volatile cryptocurrency market.

Chen compares the contrast between directly speculating in cryptocurrencies and investing in blockchain firms to the two-hundred-year-old California gold rush. He claims that “a lot of people raced in there to dig for gold, and the majority of them never made any money.” “The people who sold the shovels made the most money. The shovel sellers are the companies that are helping the growth of blockchain.”
