oZone Introduction

Cryptocurrencies have the potential to massively upgrade living standards by ‎introducing new ways for making transactions; these transactions can be done fast ‎and unbound to any border. In 2009, Satoshi Nakamoto introduced Bitcoin, the first ‎digital currency that revolutionized the financial world. Following Bitcoin, many other ‎altcoins came into existence, but arguably, Ethereum was the most important one. It ‎was introduced in 2015 by Vitalik Buterin and used the concept of smart contracts for ‎the first time, which paved the way for many other developments in the crypto ‎ecosystem.
