Bitcoin : What Is Blockchain ?

Blockchain is a hot topic around the world these days, yet for many, the technology remains an elusive concept. Yet it shouldn’t, the concept is simple once you get your head around the architecture and theory of basic crypto economics. When you do have your “a Ha” moment, the world will never seem the same to you again.

This blockchain basics guide is designed to deliver a clear, non-technical introduction to one of the most transformational & misunderstood technologies of our time. If you want to know what blockchain technology is, how it works, and it’s potential impacts, without all the technical lingo, then this post is for you.


Many people know it as the technology behind Bitcoin, but blockchain’s potential uses extend far beyond digital currencies.
Its admirers include Bill Gates and Richard Branson, and banks and insurers are falling over one another to be the first to work out how to use it.
So what exactly is blockchain, and why are Wall Street and Silicon Valley so excited about it?

What is blockchain?
Currently, most people use a trusted middleman such as a bank to make a transaction. But blockchain allows consumers and suppliers to connect directly, removing the need for a third party.
Using cryptography to keep exchanges secure, blockchain provides a decentralized database, or “digital ledger”, of transactions that everyone on the network can see. This network is essentially a chain of computers that must all approve an exchange before it can be verified and recorded.


Currently only a very small proportion of global GDP (around 0.025%, or $20 billion) is held in the blockchain, according to a survey by the World Economic Forum’s Global Agenda Council.
