What is Blockchain
As per wiki, the first work on a cryptographically secured chain of blocks was described in 1991 by Stuart Haber and W. Scott Stornetta. However, the first blockchain was conceptualised by an anonymous person or group known as Satoshi Nakamoto in 2008, and following year as core component of cryptocurrency bitcoin. He published the white paper on digital currency with title Bitcoin-Peer to Peer Electronic Cash System. He claimed that the writing of the code started way back in 2007, and the release of first units of bitcoin in 2009.
Although he used to collaborate with individuals on the open-source team, he has never revealed anything about himself. As per public bitcoin transaction log, Nakamoto's known addresses contain roughly one million bitcoins, which as of December 2017 is worth over 19 billion USD.
Many people often misinterpret Bitcoin and Blockchain as synonyms, however Bitcoin or any cryptocurrency is one of the use case of the Blockchain technology
Blockchain could be referred to as an open, transparent distributed ledger, and bitcoin is the cryptocurrency or digital currency based on Blockchain technology.
Or as Pwc defines
The blockchain is a decentralized ledger of all transactions across a peer-to-peer network. Using this technology, participants can confirm transactions without the need for a central certifying authority. Potential applications include fund transfers, settling trades, voting, and many other uses.

So what makes blockchain unique?
While a lot of cryptocurrencies, banking, and payment use cases are in the limelight, but given the nature of blockchain, it could be used in any verticals. In fact, the innovators across the world are designing digital ledger that could store any data and help the individuals.
Be it to track the diamonds or birth and death certificates, be it about storing all government records or health records or maintain your digital identity, be it about the artist who crafted his masterpiece of the musician who composed the melodious tune. All and every form of data could be stored and managed via Blockchain. If you are keen on exploring the start-ups who are offering blockchain solutions, you can visit here.
While many believe Blockchain has the potential equivalent of the Internet to disrupt the world, others just find it as a bubble that would burst out soon. A closer look at some of the famous quotes on blockchain by the known personality… does their view matter?
Adam Draper says - The blockchain does one thing: It replaces third-party trust with mathematical proof that something happened
Or as Anthony Scaramucci says - The blockchain concept was pioneered within the context of crypto-currency Bitcoin, but engineers have imagined many other ways for distributed ledger technology to streamline the world. Stock exchanges and big banks, for example, are looking at blockchain-type systems as trading settlement platforms
And Nassim Taleb Statistician, a former trader, and risk analyst quote - “Bitcoin is the beginning of something great: a currency without a government, something necessary and imperative. But I am not familiar with the specific product to assert whether it is the best potential setup. And we need a long time to establish confidence.”
And this one is my favorite…
Vitalik Buterin says - “Instead of putting the taxi driver out of a job, blockchain puts Uber out of a job and lets the taxi driver work with the customer directly.”
