# IPFS code execution example

> The build and deploy instructions as well as some of the Aqua code are outdated and the deployed services are no longer available. An updated version will be available soon.

This example showcases 2 things:

1. how it's possible to store .wasm modules on IPFS, then deploy them to Fluence as a service
2. ability to process IPFS files via a Fluence service. In this example, we get a size of a file
