Ethereum

Unlike Bitcoin, which focuses on peer to peer payment of digital currency, Ethereum is a open source public blockchain platform that looks at multiple use-cases.

Some terminologies you need to get familiar with:

Ethereum Virtual Machine (EVM): The collection of nodes (participating computer) in the peer to peer ethereum network. EVM holds the copy of blockchain.

Solidity: Most popular programming language that is used to code smart contracts in Ethereum.

Ether: The native crypto-currency of Ethereum that acts a payment for executing a smart contract.

Gas: the measure of computational effort required to execute a specific code logic. When a code is executed in EVM, it is paid for in Ether.

Mist Browser: it is the most commonly used front-end for running Ethereum applications.
