What is Blockchain?

Blockchain is often referred to as a distributed ledger because it is constantly being updated and verified by a network of computers around the world. It is not stored in a single location, which makes it more secure from hacking attacks. When a transaction is made, it is broadcast to the network, then each computer on the network verifies the transaction. Also each transaction is encrypted. Once the transaction is verified, it is added to the block. All this information is public and everyone can see the transactions that have been made. However, the identities of the people involved in the transaction are anonymous, as long as there is no link between your wallet address and your identity.

Still confused about what a blockchain actually is? Let’s simplify it. Think of a blockchain as an accounting book. You may ask, an accounting book of what? Think of it as a book or ledger for a specific network. Imagine it’s like your country’s national ledger or accounting book. In this ledger, every transaction or event that occurs within the country is meticulously recorded. Now, who’s in control of this ledger? Well, it’s not under the control of any single entity – it’s a collective effort. Every citizen in the country plays a role in maintaining this ledger, and every citizen gets an identical copy of it. Whenever a new transaction occurs, it’s added to the ledger, and this updated version is distributed to all citizens.

However, in any system, there’s always the potential for bad actors. These individuals might attempt to deceive the network by creating false transactions, claiming they have more money than they actually do. If these false transactions were accepted, it would essentially mean creating money out of thin air, leading to inflation and a devaluation of the currency. This harms everyone. That’s where the strength of decentralization comes into play.

The citizens, or the network users, compare their ledger copies and review the transaction history to ensure the truth is being told. Through a democratic process, the majority determines whether to accept or reject these questionable transactions. This is the essence of decentralization in a blockchain. The power rests with the majority, and decisions are made collectively.
