In pursuit of this collaborative mission, Fastly has joined the World Wide Web Consortium and will participate in the WebAssembly Working Group, and continues its contributions to the newly-incorporated Bytecode Alliance, a nonprofit dedicated to creating a new, more secure software ecosystem.

Led by Fastly's WebAssembly team, the evolution of Cranelift's secure sandboxing is one example of the Bytecode Alliance's commitment to fostering more secure software development.

The ecosystem the Bytecode Alliance aims to build, leveraging WebAssembly and other standards and community efforts, will resolve potentially dangerous shortcomings in execution semantics and sandboxed environments within the software supply chain, addressing development gaps in trust and data integrity.

Alongside Bytecode Alliance members, Fastly's WebAssembly team has specifically prioritized contributing to Wasmtime, a WebAssembly runtime, and Cranelift, an open-source, next-generation code generator for use in WebAssembly to provide sandbox security functionality.

Cranelift's advanced security controls - separately verified by rigorous Fastly, Mozilla, and Bytecode Alliance assessments - are crucial to the speedy yet secure-by-design technology that underlies Fastly's serverless compute solution ComputeEdge, and is uniquely suited to help power a more secure ecosystem for all who work with, collaborate on, and contribute to WebAssembly.

Fastly and its Bytecode Alliance partners are committed to WebAssembly as a mission-critical technology that enables an interoperable software community, where organizations rally around shared foundations.
