Dapps are interfaces that interact with the blockchain by using smart contracts. These smart contracts form the logical core of any Dapps. Overall, Dapps look and behave like regular web and mobile applications, except that they interact with a blockchain and in different ways. Bitcoin has been the first decentralized app or DApp debuted in 2009. The most popular dapps at present are decentralized crypto exchanges, or DEXs. They enable people to swap one cryptocurrency for another without the need for a centralized gatekeeper.
What are the benefits of Dapps?
Dapps are built on top of decentralized blockchain networks such as Ethereum and usually have the following benefits:
Immutability: Nobody can change any information once it’s on the blockchain.
Tamper-proof: Smart contracts published onto the blockchain cannot be tampered with without alerting every other participant on the blockchain.
Transparent: Smart contracts powering Dapps are openly auditable.
Availability: As long as the Ethereum network remains active, Dapps built on it will remain active and usable.
