Ethereum was released in 2015 as a second generation cryptocurrency. It added a powerful smart contract language with binary code stored in the blockchain along with transactions. This language, Solidity, allows for the development of smart contracts, which are self-enforcing and decentralized computer programs which implement business rules and live on the blockchain. Ethereum has gained much popularity and rose to become the #2 cryptocurrency (as of early 2018) in market capitalization.
What Makes It Different?
Ethereum introduced the Solidity smart contract language which is considered a major improvement over Bitcoin’s limited script language.
Who is Behind Ethereum ?
