Decentralized Finance Dapp provides a new way to interact with web applications. Decentralized applications are based on blockchain technology that runs on a peer-to-peer (P2P) network on various servers rather than a traditional central server. However, these DeFi Dapp are built on the notion of smart contracts and the consensus mechanism, which means when an application is decentralized, it is first built with the underlying blockchain technology and pushed to a preferred blockchain system. Investors can contact professional experts from blockchain companies to make a decentralized finance Dapp at an affordable price.
