Blockchain- a brief overview

Hello everyone, today I will be talking about yet another popular technology- Blockchain.

Just a brief overview of it.

“ A blockchain, originally block chain, is a growing list of records, called blocks, which are linked using cryptography. Each block contains a  cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a  Merkle tree ). ”

-Wikipedia

Simply, Blockchain is the technology that covers digital currency (like Bitcoin, Litecoin, Ethereum, and others). This technology allows digital information to be distributed, but not copied. That means each piece of data can only have one owner.

Why Is It Called Blockchain?
A block is a record of new transactions. When a block is completed, it’s added to the chain.

So, Blockchain is a way to save data and make it immutable. That sounds great, but the big question, of course, is: how does that work? The working is quite complex, you can check Wikipedia for this.

The need for Blockchain?

• Blockchain will enhance the reach of a businesses

• It will ensure swift transactions

• Blockchain highly restricts frauds

• Blockchain is reliable and transparent

• Immutability

• It is Cost effective

The distributed ledger technology used in blockchain offers multiple benefits to businesses that make a difference when implementing a solution that requires a high degree of trust for business
transactions.

Blockchain can process transactions faster because it doesn't use a centralized infrastructure. The distributed nature of blockchain provides a huge level of trust. The unchangeable property of blockchain and its public availability among its users, whether in a public ledger or a private one, provides transparency. Any user of the system can query transactions on a real-time basis.

In short, by adopting Blockchain people across the world can say goodbye to the middleman, dependence on banks, legal agencies, and hackers.
