Ethereum is one of literally thousands of cryptocurrencies that have sprung up over the last few years. As the brainchild of 8 co-founders, Ethereum made its debut in 2015. The cryptocurrency or platform is called Ethereum, while the individual unit is called an ether (2 ether, 17 ether, etc.)
Ethereum operates on a decentralized computer network, or distributed ledger called a blockchain, which manages and tracks the currency. It can be useful to think of a blockchain like a running receipt of every transaction that’s ever taken place in the cryptocurrency. Computers in the network verify the transactions and ensure the integrity of the data.
This decentralized network is part of the appeal of Ethereum and other cryptocurrencies. Users can exchange money without the need for a central intermediary such as a bank, and the lack of a central bank means the currency is nearly autonomous. Ethereum also allows users to make transactions nearly anonymously, even if the transaction is publicly available on the blockchain.
While the whole field is referred to in terms of currency, it may be more useful to think of crypto as a token that can be spent for a specific purpose enabled by the Ethereum platform. For example, sending money or buying and selling goods are functions enabled by the coin. But Ethereum can do a lot more, and it can also form the basis for smart contracts and other apps.
