1. Smart Contract Foundation:
- DApps operate using smart contracts, which are self-executing contracts with predefined rules written in code. These contracts automatically execute actions when specific conditions are met.
2. Distributed P2P Networks:
- The back-end code of DApps runs on distributed peer-to-peer networks, meaning there's no central server. Instead, the application is powered by a network of interconnected computers (nodes) that collaborate to maintain the system.
3. Smart Contract Execution:
- When certain conditions specified in a smart contract are met, all nodes in the network execute the tasks outlined in the contract. This decentralized execution ensures transparency and eliminates the need for a central authority.
4. Immutable Code on the Blockchain:
- Once a smart contract is deployed on the blockchain, its code becomes immutable. This means that it's challenging to alter or destroy the code once it's in place. The decentralized nature of the blockchain ensures the integrity and permanence of the smart contract.
5. Continued Accessibility:
- Even if the team behind the DApp disbands or ceases operation, users can still access and use the DApp. The smart contract, residing on the blockchain, remains operational, and users can interact with it as long as the underlying blockchain network is active.
๐ Key Point:
- DApps leverage smart contracts and decentralized networks, providing a secure and transparent environment where users can interact with the application based on predefined rules. The immutability of smart contracts on the blockchain ensures the longevity and accessibility of DApps, independent of the entities that initially developed them.
