Blockchain development refers to the process of creating and implementing blockchain technology, which is a decentralized and distributed digital ledger. It involves designing, coding, and deploying blockchain networks or applications that leverage the unique properties of blockchain, such as immutability, transparency, security, and decentralization.

Blockchain development requires a solid understanding of blockchain technology, cryptography, distributed systems, and software development. It often involves programming languages like Solidity (for Ethereum), Golang, or other language-specific to the chosen blockchain platform.
