WasmEdge Proprietary Extensions

A key differentiator of WasmEdge from other WebAssembly runtimes is its support for non-standard extensions. The WebAssembly System Interface (WASI) provides a mechanism for developers to extend WebAssembly efficiently and securely. The WasmEdge team created the following WASI-like extensions based on real-world customer demands.

• Tensorflow. Developers can write Tensorflow inference functions using a simple Rust API, and then run the function securely and at native speed inside WasmEdge.
• Image processing. WasmEdge uses native libraries to manipulate images for computer vision tasks.
• KV Storage. The WasmEdge storage interface allows WebAssembly programs to read and write a key value store.
• Network sockets. WasmEdge applications can access the network sockets for TCP and HTTP connections.
• Command interface. WasmEdge enables webassembly functions execute native commands in the host operating system. It supports passing arguments, environment variables, STDIN/STDOUT pipes, and security policies for host access.
• Ethereum. The WasmEdge Ewasm extension supports Ethereum smart contracts compiled to WebAssembly. It is a leading implementation for Ethereum flavored WebAssembly (Ewasm).
• Substrate. The Pallet allows WasmEdge to act as an Ethereum smart contract execution engine on any Substrate based blockchains.
