What is Ethereum?

Ethereum is a decentralized blockchain platform for “building unstoppable applications”, while Ether is the cryptocurrency used on this platform. Ethereum can be used for virtually any kind of transaction or agreement (to put it another way, any kind of activity that has an economic or governance aspect), at a lower cost than conventional alternatives, such as debit card payments, PayPal, and ballot voting, in a way that is decentralized, trustless (no intermediary like a bank is needed, Bob can send X ETH directly to Alice), secure, safe and live (with some assumptions like an honest majority of securitors), and censorship-resistant.

What is a Smart Contract?

A Smart Contract is a computer program that directly controls the transfer of digital assets between parties under certain conditions. A smart contract defines the rules and penalties related to an agreement in the same way that a traditional contract does and it can also automatically enforce those obligations. Most applications running on the Ethereum Blockchain are based on smart contracts.

Educational Ethereum Videos

Just about everything about Ethereum, Ether, smart contracts and dapps (decentralized appilcations) can be learned by watching educational videos on YouTube and decentralized tube services like dLive. Here we present some videos to help you understand the Ethereum Platform from different perspectives.
