Ethereum (ETH)
Ethereum is a decentralised smart contract platform. Like Bitcoin, the Ethereum network has a token (Ether), a blockchain, nodes, and miners. However, unlike Bitcoin, the blockchain maintains consensus for a ‘virtual computer’ dubbed the EVM (Ethereum Virtual Machine). Distributed smart contracts can be created and deployed on the EVM.
Ether is the native token on the Ethereum network. There are around 100 million Ether on the network today, and the token is used to incentivise miners to run their mining hardware (which helps keep the network decentralised).
EOS (EOS)
EOS is a blockchain architecture designed to enable vertical and horizontal scaling of decentralised applications by creating an operating system-like construct upon which applications can be built.
The software provides accounts, authentication, databases, asynchronous communication, and the scheduling of applications across many CPU cores or clusters.
The resulting technology is a blockchain architecture that eliminates user fees and allows for quick and easy deployment and maintenance of decentralised applications in the context of a governed blockchain.
