I did not know many thing about Ethereum,

Ethereum is a ledger technology that companies are using to build new programs. Both Bitcoin and Ethereum operate on what is called "blockchain" technology, however Ethereum's is far more robust. If Bitcoin was version 1.0, Ethereum is 2.0, allowing for the building of decentralized applications to be built on top of it. In a nutshell: it's great for innovation. Furthermore, there is heavy support behind Ethereum's technology in what is called The Enterprise Ethereum Alliance. This is a super-group of Fortune 500 companies that have all agreed to work together to learn and build upon Ethereum's blockchain technology—otherwise referred to as "smart contract" technology. In this case, "smart contracts" mean that demanding business applications can automate extremely complex applications.

Thanks for the great informative material and links. I have learnt a lot.
