}Move is a safe, resource-oriented programming language originally developed for the Libra (now Diem) blockchain. It focuses on correctness, security, and formal verification, particularly for digital assets and smart contracts.
Origin & Creator
Move was created by the Libra (Diem) team at Facebook around 2019. It evolved to provide safe resource management for blockchain assets and has been adopted by several new-generation blockchains.
Industrial Note
Move is highly focused on financial and asset management applications in blockchains, especially where strict ownership rules and resource safety are required. It’s ideal for token systems, NFT platforms, and DeFi primitives.
