 # Trusted Server 
 
-:information_source: Trusted Server is an open-source, cloud based orchestration framework and runtime for publishers. It moves code execution and operations that traditionally occured in browsers (via 3rd party JS) to secure, zero-cold-start [WASM](https://webassembly.org) binaries running in [WASI](https://github.com/WebAssembly/WASI) supported environments. It importantly gives publishers benefits such as: dramatically increasing control over how and who they share their data with (while maintaining user-privacy compliance), increasing revenue from inventory inside cookie restricted or non-JS environments, ability to serve all assets under 1st party context, and provides secure cryptographic functions to ensure trust across the programmatic ad ecosystem.
