Buy and sell products, pay bills, transfer money, store documents: the digital era has simplified many daily actions. What with fraud, identity theft and phishing, the network is certainly not a completely risk-free place.

Blockchain is a technology that can revolutionize the way we manage the storage and distribution of information on the Web, protecting it from dangerous attempts of attack, theft and forgery.

But what exactly is it? Blockchain is a chain of blocks.

Each block contains information that depends on the type of chain you are using.

For example, a blockchain dedicated to monetary transactions (like that of bitcoins and other cryptocurrencies) is composed of blocks that contain all the information concerning whoever is transfering the money, who receives it, and how much the exchange costs. Like a digital ledger.

How does a blockchain protect data? By using different levels of security. And this security issue has not gone unnoticed to the eyes of entrepreneurs, banks, researchers and governments all over the world.
