Backend vs. Frontend Decentralization
In general, dApps are decentralized on the backend: this means that an app’s underlying smart contracts are executed by nodes on a blockchain. Although dApps can be frozen due to security issues, they generally operate as long as the blockchain is functional. This means that social, legal, or political pressure cannot shut down a dApp.
