A Blockchain Developer specializes in developing and implementing architecture and solutions using blockchain technology. They are responsible for creating the blockchain system's framework, developing smart contracts, and building decentralized applications (DApps) that operate on blockchain technology. For example, they might work on developing a decentralized finance (DeFi) application that allows users to lend or borrow funds without going through a traditional financial institution, or a blockchain-based game where players truly own their in-game items as NFTs. These developers play a critical role in the design, implementation, and security of blockchain systems.
