Blockchain explained

A good analogy for learning blockchain technology is Google Docs. When we create a document and share it with a group of individuals, the document is disseminated instead of being duplicated or transferred.

This creates a decentralized distribution chain in which everyone has real-time access to the document. No one is shut out while waiting for another party to make changes, and all changes to the document are logged in real-time, making the process transparent.

Although Blockchain appears to be pretty complex, its core notion is actually pretty simple.

Blockchain, also known as a database, is an online ledger. To understand Blockchain, you must first understand what a database is. It is a compilation of information stored in a digital format on a computer system. The stored data is frequently structured in a table format that makes finding and filtering for specific information easier.

Why Is Blockchain Technology Generating So Much Buzz?

Blockchain, like the early internet, is difficult to comprehend and anticipate, but it has the potential to become commonplace in the trade of digital and physical commodities, information, and online platforms.

Many attempts to generate digital currencies have been made in the past, but they have all failed – mostly because of a distinct lack of trust. How can we believe that if someone invents a new kind of money called Y, they will not make themselves the richest person on the planet, or better yet, hide important information and make you (as the investor) go bankrupt?

Bitcoin was created by utilizing Blockchain (or databases) to address this issue. So, a person in control of most regular databases, such as an SQL database, can change the entries without needing to go through lengthy sub-processes.

Blockchain is also unique because no one is in charge; instead, the individuals who utilize it run it.

Structure of Storage

A regular database and a blockchain have quite different ways of structuring data. A blockchain is a digital record that divides data into blocks, in which each comprises a collection of information.

When a block's storage capacity is reached, it is linked to the preceding block, forming a data chain termed as a "blockchain." After the freshly added block is constructed into a new block and completed, it is then linked to the Blockchain. This linking creates a regular structure that is easy to navigate and use.


Because of Bitcoin's decentralized structure, all transactions can be freely monitored via a local node or blockchain explorer, which lets anyone witness payments as they happen. Each node maintains its own copy of the chain, modified as new blocks are validated and inserted. This means that if you wanted to, you could pursue Bitcoin wherever it went.


It's useful to consider Blockchain in terms of its implementation. The Blockchain of Bitcoin, like that of a database, is recorded by a distributed network.

This Blockchain is essentially a database that stores every single Bitcoin transaction ever done. Unlike other systems, Bitcoin's structures are not all stored in the same facility, and each system or collection of computer programs is operated by a single individual or group of people.

Advantages and Disadvantages of Blockchain

Despite its intricacy, block chain's potential as a decentralized record-keeping system is practically limitless. Blockchain technology may have benefits beyond those listed above, ranging from increased user privacy protection to lower processing fees and fewer mistakes.

  • Increases accuracy by eliminating the need for human verification.
  • Cost savings by obviating the need for third-party verification.
  • Decentralization makes it more difficult to tamper with data.
  • Payments are safe, secure, and quick.
  • Offers transparent technology.
  • Bitcoin mining has a high technology cost.
  • Transactions per second are low.
  • Bitcoin has a history of being used in illegal operations.
  • Lack of strict regulations.

The Takeaway

Security is both a strength and a weakness for Blockchain. Cryptocurrency transactions, such as paying with crypto, dealing in crypto, and lending bitcoin, are private and secure, thanks to the way blockchains are designed.
