What is dapp and why is it important?

Good explanation of Dapp features & benefits from a “decentralized backend”. I would add a frontend aspect to the “Flawless incorporation with cryptocurrency”: Dapps allow strong blockchain wallet integration. A Dapp can easily triggered a blockchain (trans)action done by the wallet (e.g. payment, send a token to a friend, trade a gaming asset, or breed Cryptokitties <3 ). How? By having the Dapp & the wallet together. You can integrate a wallet within your Dapp, but it is often more user-friendly to have several Dapps working with the same “external” blockchain wallet. For a lot of Dapps that are browser-based: a) Standard browser & wallet as plugin (e.g. Metamask, Scatter, TronLink); or b) wallet with browsing features (e.g. Cipher, Trustwallet, Casa Tookan, Toshi-coinbase)
