Frequently Asked Questions
A public blockchain is a decentralized network open to anyone for participating in transactions and validation. It uses cryptography and consensus algorithms to ensure transparency, security, and immutability of data.
To build a DApp on Ethereum, developers write smart contracts in Solidity, test them on testnets, then connect the contracts to user-friendly frontends using Web3 tools. Wallet integration like MetaMask is essential for user interactions.
Smart contract development includes creating secure, self-executing code for applications such as DeFi protocols, NFT platforms, and DAO governance, typically on chains like Ethereum, Solana, or Polygon.
Public blockchains offer open access, decentralization, and stronger security through distributed consensus. Private blockchains provide controlled access and may be suitable for internal enterprise use, but lack full transparency.
Ethereum is the most widely used, followed by Solana, Polygon, and Binance Smart Chain, each offering unique benefits like faster transactions, lower fees, or advanced interoperability.
