Consider understanding the nature of Cairo public inputs, which are non-secret inputs for zkSNARKs circuits, and then identifying the serialization format, such as JSON or binary, used for these inputs; proceed to implement deserialization logic using appropriate libraries or custom code based on the serialization format, ensuring to include robust error handling for potential issues with corrupted or incorrect serialized input; further, develop comprehensive test cases to validate the correct functioning of the deserialization logic under various scenarios; subsequently, integrate this deserialization logic into the Cairo codebase, updating relevant sections to utilize the deserialized inputs effectively; don't forget to document the changes made, especially the new deserialization functionality, for future reference; seek peer reviews and conduct thorough quality assurance to identify and address any potential bugs that may arise; finally, upon successful testing, proceed to deploy the updated code with the new deserialization functionality in place.
