Pull Request Overview

This pull request enables the storage of prover inputs in SSZ format, as demonstrated by the new test that validates conversion between JSON and SSZ representations.

• Adds a new test file to verify the conversion of prover inputs to SSZ and back to JSON.
• Incorporates debugging code to output JSON files on failure for further inspection.

• [nitpick] Consider adding a call to t.Helper() at the beginning of this helper function to improve error reporting clarity in test failures.

func LoadProverInputJSON(t *testing.T, path string) *input.ProverInput {

Debugging file write statements are left in the test; consider removing them or adding a flag to prevent unwanted side effects during automated test runs.

	// issue: the uncles and transactions field is not being serialized correctly

The error return from os.WriteFile is not checked; consider handling this error to ensure that debugging outputs are written as expected.

Suggested change

	os.WriteFile("original.json", originalJSON, 0644)
	os.WriteFile("final.json", jsonData, 0644)
	if err := os.WriteFile("original.json", originalJSON, 0644); err != nil {
	t.Fatalf("Failed to write original JSON to file: %v", err)
	}
	if err := os.WriteFile("final.json", jsonData, 0644); err != nil {
	t.Fatalf("Failed to write final JSON to file: %v", err)
