WebAssembly, or Wasm, is a binary instruction format that allows code to run in web browsers at near-native speed. It’s designed to be a portable compilation target for programming languages, enabling developers to write code in languages like C, C++, or Rust and run it in a secure and efficient manner.In the context of blockchain, Wasm enhances smart contracts by providing a versatile and efficient way to execute code. This is particularly useful for decentralized applications, as Wasm allows developers to create complex functionalities without being limited to specific languages.The modular nature of Wasm makes it easier for different systems to interact with one another. It supports decentralized development and enables more sophisticated applications to be built on blockchain platforms. Additionally, it greatly improves the performance of smart contracts, allowing for faster execution and lower transaction costs.Overall, Wasm is a powerful tool that bridges the gap between conventional programming and blockchain technology, making it easier for developers to create efficient and scalable applications.
