Ethereum is a network of computers around the world that follows a set of rules called the Ethereum Protocol.
The Ethereum network serves as the foundation for communities, applications, organizations, and digital assets that anyone can build and use.
You can create an Ethereum account from anywhere, at any time, and explore a world of applications or build your account.
The key innovation is that you can do all of this without having to trust a central authority that can change the rules or restrict your access.
