Dapps and smart contracts
The creation of Dapp is one of the most important features of Ethereum. In addition to decentralization, there are some other functions that Dapp must have:
The source code of Dapp should be open to everyone.
The application must have some kind of token to support itself.
The application must be able to generate its own token and have a built-in consensus mechanism.
Sounds great! So, how do you build them? You need to use solidity to encode smart contracts.
Developers use a programming language called Solidity, which is a purposeful, concise, loosely typed language with a syntax that is very similar to ECMAScript (Javascript).
