Ethereum is a digital platform based on a decentralized blockchain technology that has its own cryptocurrency called Ether (ETH).
Just like Bitcoin, the Ethereum blockchain tracks the ownership of the digital currency. It also focuses on running programming code of a range of decentralized apps (dapps) such as security programs, voting systems, and payment methods.
Ethereum enables users to create self-executing contracts, called smart contracts, that are executed automatically when predetermined conditions are met. These actions can include releasing funds to the relevant parties, registering a vehicle, sending notifications, or issuing a ticket.
Like Bitcoin, Ethereum operates outside the control of central authorities such as banks and governments.
You can purchase Ether directly via an online exchange platform like Coinbase and store it in a digital wallet.
Similar to other cryptocurrencies, Ether can be used to buy or sell goods as well as to build, publish, promote, and deploy apps on the Ethereum platform, using Ether as a means of payment.
