Ethereum is a brand-new and open blockchain platform, which allows anyone to build and use decentralized applications running through blockchain technology. Just like Bitcoin, Ethereum is not controlled by anyone or owned by anyone-it is an open source project founded by many people all over the world. Different from Bitcoin protocol, the design of Ethereum is very flexible and adaptable. Creating new applications on the platform of Ethereum is very simple. With the release of Homestead, anyone can safely use the applications on the platform.
