DApps (2016)
DApps or Decentralized Applications is an open-source application that operates autonomously on a decentralized blockchain & can only be built on Smart Contract networks.
All the DApps work on a specific platform that is compatible with its unique code and not on standard web browsers.
The first DApp on Ethereum to gain attention was a collectibles game known as CryptoKitties, which crashed the Ethereum network at the height of its popularity.
