Ethereum is a open-software platform that is operating using blockchain technology co-founded by Vitalik Buterin and Joseph Lubin. Ethereum was released 2015. Ethereum gives a cryptocurrency called ether that can be moved from different accounts. While Bitcoin was designed for consumer payments, Ethereum was designed to allow for more complex party interactions called Smart contracts. These can be defined using Solidity.

Ethereum ERC Tokens

An ERC token is a fungible tradable asset that operates on Ethereum's blockchain. The Ethereum Request for Comments (ERC) for tokens is a way of describing a set of functions and rules that the token should posses and follow. The three most common standards can be seen here:

Development on Ethereum

Ethereum has a set of tools for developers to create, deploy and interact with smart contracts, tokens, DApps and more.

Ethereum Name Service

The Ethereum Name Service (ENS) allows Ethereum users to replace their long wallet addresses with “human readable names” attached to a domain. The two available TLDs are:
