Blockchain Technology Facts: What Is It, How It Works

Some people believe that blockchain technology could be one of the most important inventions of the 21st century. The innovation accumulates a lot of public attention. However, not everyone actually understands what it is and how it can influence our lives. But what is it, really?

If you are interested in cryptocurrency and want to invest in it, it is better to find all the necessary information about the blockchain technology before you invest your money. You can find everything online – from how to buy Shiba Inu (SHIB) in 5 steps to tips in diversifying your portfolio. The more information you have, the more successful your investments will be. 

About Blockchain

At its simplest, a blockchain is a digital ledger of transactions. It’s like a giant spreadsheet that is duplicated thousands of times across a network of computers. Every time someone wants to add a new transaction to the ledger, they must first solve a complex mathematical problem. This process, known as “mining,” takes time and energy. As a result, there is a finite supply of new bitcoins that can be created.

When a new block of transactions is created, it is added to the blockchain in a linear, chronological order. The cryptographic hash of the previous block, a timestamp, and transaction data are contained in each block. The blockchain technology is used by Bitcoin nodes to identify correct Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

The decentralized, transparent nature of blockchain technology was first described in a white paper by an unknown individual or group known as Satoshi Nakamoto in 2008. The original function of blockchain was to serve as the accounting method for Bitcoin transactions. But the applications of blockchain technology extend far beyond digital currencies.

At its core, blockchain is a distributed database that allows direct transactions between two parties without the need for an intermediary. It’s like a digital ledger that is duplicated thousands of times across a network of computers. This decentralized structure allows for more secure and transparent transactions.

By eliminating the middleman, blockchain technology has the potential to disrupt many industries, including banking, law, and even government. 

Applications of Blockchain Technology

While originally designed for digital currencies, blockchain technology has many other potential uses. Here are a few examples:

  1. Banking: Blockchain can be used to streamline the banking process. For example, international payments can be made quickly and easily without the need for a middleman.
  2. Law: Blockchain can be used to create tamper-proof legal contracts. This would allow for the execution of smart contracts, which are self-executing contracts that can be executed without the need for human intervention.
  3. Government: Blockchain technology has the potential to streamline government processes and make them more transparent. For example, land registries can be stored on the blockchain, which would make it more difficult for corrupt officials to sell off public land for personal gain.
  4. Supply Chain Management: Blockchain technology can be used to monitor the transportation of goods along a supply chain. This would allow businesses to ensure that their products are being produced ethically and are not being counterfeit.

These are just a few of the potential uses for blockchain technology. However, the whole potential of this new technology is still being explored.

Blockchain pros and cons

Like any technology, blockchain has its advantages and disadvantages.


  • Decentralized: Blockchain is a decentralized system, which means that it is not controlled by any one person or organization. This makes it more secure and transparent.
  • Secure: Blockchain uses cryptography to secure transactions. It’s more difficult for hackers to steal data because of the essence of the technology.
  • Fast: Blockchain transactions are typically much faster than traditional bank transfers.
  • Reduced costs: Blockchain can help to reduce the costs of traditional middlemen, such as banks and lawyers.


  • Scalability: Blockchain is still a new technology, and it is not yet clear how well it will scale.
  • Privacy: Blockchain is a public ledger, which means that transaction information is publicly available. This could be a problem for businesses or individuals who want to keep their information private.
  • Complexity: Blockchain technology is complex, and it can be difficult to understand how it works.

Despite its disadvantages, blockchain technology has the potential to revolutionize the way we do business. It is secure, fast, and decentralized, which could make it the perfect solution for many industries. Only time will tell how well it will ultimately be adopted.
