What is the Michelson Language?

Key Characteristics

• Stack-Based Language: Michelson is a stack-based language, meaning it manipulates data by pushing and popping values onto a stack. This approach is similar to the Ethereum Virtual Machine (EVM), but Michelson represents programs in a more human-readable text format12.
• Strong Typing: Michelson enforces strict type-checking, which helps prevent many common programming mistakes before contracts are deployed. This makes writing safe and robust smart contracts more feasible1.
• Designed for Formal Verification: Michelson’s design makes it easier to mathematically prove properties about smart contracts, an important aspect for ensuring correctness and security, especially for financial applications.
• Low-Level; Compiled to by High-Level Languages: While developers can write directly in Michelson, several higher-level languages like LIGO exist, which are then compiled into Michelson for deployment on Tezos32.
• Human-Readable Syntax: Unlike some bytecode formats, Michelson is written in a clear textual form, making it more accessible for code review and debugging14.

Typical Usage

• Michelson is used primarily for:
  • Developing decentralized applications (dApps)
  • Implementing token standards (e.g., Tezos FA1.2, FA2)
  • Writing secure, immutable smart contracts for DeFi, NFTs, and other use cases on the Tezos blockchain456.
