What is Blockchain?

Blockchain is a technology that makes data transfer secure and transparent.

It is a data structure that cannot be changed.

Each block of information is recorded in such a way that it cannot be changed without everyone's agreement.

The idea of blockchain was first presented in 1991.

But the original model was launched in 2008 with Bitcoin. The blockchain of Bitcoin, created in 2009, is the first and best-known example of this technology.

In the beginning, blockchain was only used for Bitcoin transactions.

But in 2014, it began to be explored for other applications.

To understand how blockchain works, think of a Sudoku puzzle.

It's hard to solve, but easy to check.

The proof-of-work (PoW) consensus mechanism uses processing power to solve complex calculations. This strengthens the security of the network.

Aspect	Blockchain Bitcoin	Visa
Time to Add Block	10 minutes	N/A
Transactions per Second	7	65.000
Participants without a Bank Account	1.7 billion	N/A

THE blockchain can greatly reduce manual tasks and optimize operations.

It can also reduce voter fraud and transaction costs. Our financial system benefits from preventing double spending and fraud.

The networks of blockchain Public transactions allow anyone to access and validate transactions.

This helps with transparency and security of the system.

THE blockchain definition and its impact are always evolving, revolutionizing business operations globally.
