Abstract: Ethereum is a blockchain-based decentralized platform that provides a way for people to develop, publish and use decentralized apps. What is Ethereum? Ethereum is a blockchain-based decentralized platform that provides a way for people to develop, publish and use decentralized apps. Ethereum is more than just a digital currency, it is a blockchain-based decentralized platform that provides a way for people to develop, publish and use decentralized apps. Ethereum is a decentralized platform, based on the blockchain, for a new kind of internet. Ethereum is a network that is running on a blockchain to create a new kind of internet. This internet is based on a decentralized network of computers that are all running the same software. The software is designed to update the state of the blockchain to keep track of who owns what. Some people have called Ethereum the “world computer” because it can be used to run applications that are completely detached from any physical location. The applications are called “smart contracts” and they can be used to create a wide variety of things that have value, such as money, property, shares, and much more. Ethereum is a public, open-source blockchain that is used to build decentralized applications. Ethereum abstracts the complexity of building a blockchain, reducing the time and costs.
