Ethereum is a publicly distributed blockchain network that aims to focus its blockchain to run decentralized programs such as Dapps, which is a supported application by Ethereum smart contracts. There are many examples of Dapps listed in the smart contract ethereum. And so far the smart contract ethereum facilitates any application that developers want to operate, such as digital or crypto asset exchange platforms, stocks, gambling platforms, advertising platforms, payment systems, insurance platforms, company review platforms, voting platforms, money lending, and so on. Ethereum facilitates the creation of decentralized applications where the system is not controlled by any party, safe and open to the public. I believe that ethereum can revolutionize the internet with breakthroughs.
