How Blockchain could Change the World?

Many people understand the meaning of “blockchain” to be associated with Bitcoin, the digital currency. While the bitcoin has gotten lot of publicity because of its anonymous founders and many ups and downs in inflations, it’s the blockchain infrastructure behind it that makes it a world-changing innovation.

In fact, blockchain has the potential and power to change many of the economic structures and society.

Why Blockchain matters?

Building a Blockchain

What exactly a Blockchain is? It’s just a file itself which is as same as database file. You may know that there are two main elements of Blockchains – Block and Chains. In which, blocks are store transaction data and determined with a unique string, called hash that is identified algorithmically by block contents.

Apart from this, those transactions are strung with each other chronologically to create the chain, are grows as more transactions are added.

The blockchain itself is hosted over a variety of computer nodes, it’s a simple computers that have distributed copy of blockchain. By distributing the validation process over numerous nodes, blockchain makes it extremely hard for people to do fraudulent activity into the chain.

Blockchain and Bitcoin

In order to get a sense of what makes blockchain special, it’s also important to know little things about bitcoin and how it works. As you may know, the idea behind bitcoin was to develop a digital currency that couldn’t be controlled by central authority. It means no central bank would control the supply of Bitcoins and no banks to store it. It will be managed by a massive peer to peer network and central of this network was Blockchain. It serves as the distributed public ledger that tracks and verifies every transaction of Bitcoin. A DPL has several benefits over traditional systems of processing and recording transactions:

• It’s frictionless, as there is no intermediary, i.e. credit card companies and banks.
• It’s authoritative, only one publically accessible ledger authoritative.
• It is purely secure against errors and frauds, every alteration to ledger is recorded.

Bitcoins and Blockchains are closely related to each other as they both are developed simultaneously. It doesn’t mean both are the same thing, bitcoin is currently most popular application of blockchain just like Wikipedia is most prominent example of wiki framework.
