Understand why Ethereum exists, and you’ll get why it’s a big deal
The world’s second-most-valuable cryptocurrency is also its most interesting — but in order to understand it, you must first understand its origins.

In the beginning, there was Bitcoin. The cryptocurrency has for many become synonymous with the idea of digital money, rising to a market capitalization of nearly $100 billion. But the second-most-valuable currency, Ether, may be far more interesting than its headline-grabbing older sibling. To understand why it’s so popular, it helps to understand why the software that runs it, called Ethereum, exists in the first place.
On Halloween in 2008, someone or some group of people using the name Satoshi Nakamoto published a white paper describing a system that would rely on a “decentralized” network of computers to facilitate the peer-to-peer exchange of value (bitcoins). Those computers would verify and record every transaction in a shared, encrypted accounting ledger. Nakamoto called this ledger a “blockchain,” because it’s composed of groups of transactions called “blocks,” each one cryptographically linked to the one preceding it.
