Ethereum is a blockchain-based software platform that is primarily used to support the world's second-largest cryptocurrency, after Bitcoin, in terms of market value. Ethereum, like other cryptocurrencies, may be used to transfer and receive value globally without the need for a third party to monitor or intervene. The Ethereum blockchain's major use case today is value exchange, which is commonly done using the blockchain's native token, ether. However, many developers are working on Ethereum because of its long-term potential and the inventors' lofty ambition of using the cryptocurrency to offer consumers more control over their wallets and internet data. The grandiose concept – which has led to Ethereum being dubbed the "global computer" – has been met with skepticism from some who believe it will fail. However, if this experiment goes as planned, it will result in apps that are significantly different from those created by Facebook and Google, which consumers deliberately or unintentionally trust with their data.
