Technologies Involved

These technologies are closely related to the FVM project and the SDK, so it is important for you to understand what they are about.

What is WebAssembly?

The native runtime of the Filecoin Virtual Machine is WebAssembly (WASM). WebAssembly (abbreviated WASM) is a binary instruction format for a stack-based virtual machine. WASM is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications.

Some of its features are:

• Efficient and fast
• Safe
• Open and debuggable
• Part of the open web platform

For more information, please refer to the WebAssembly web page.

What is AssemblyScript?

AssemblyScript compiles a variant of TypeScript (a typed superset of JavaScript) to WebAssembly using Binaryen.

• AssemblyScript targets WebAssembly's feature set specifically, giving developers low-level control over their code.
• Its similarity with TypeScript makes it easy to compile to WebAssembly without learning a new language.
