What is Blockchain Technology | What is Blockchain ?

Blockchain is a system of recording information in a way that makes it difficult or impossible to alter, hack or spoof a system.

A blockchain is essentially a digital ledger of transactions that are duplicated and distributed across a network of computer systems on the blockchain. Each block in the chain consists of multiple transactions, and each time a new transaction occurs on the blockchain, a record of that transaction is added to each participant's ledger. A decentralized database managed by multiple participants is known as Distributed Ledger Technology (DLT).

Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a hash.

This means that if a block in a chain was altered, it would be immediately apparent that it had been tampered with. If hackers wanted to corrupt a blockchain system, they would have to replace each block in the chain, across all distributed volumes of the chain.

Blockchains like Bitcoin and Ethereum are growing steadily and steadily as blocks are being added to the chain, which adds significantly to the security of the ledger.

There have been many attempts in the past to create digital money, but they have always been unsuccessful.

The prevailing issue is trust. If someone creates a new currency called X dollars, how can we be sure that they will not give themselves a million X dollars, or steal their X dollars for themselves?

Bitcoin was designed to solve this problem by using a specific type of database called a blockchain. Most common databases, such as SQL databases, have someone in charge who can change the entries (e.g. giving yourself a million X dollars). Blockchain is different because no one is in charge; It is run by the people who use it. What's more, Bitcoin cannot be counterfeited, hacked or double spent - so those who own this money can trust that it has some value.
