Prove You Are a Robot | Iterative Processing Endurance

Prove you are a robot

Starting with the issued seed below, calculate SHA-256 exactly 37 times. Submit the hexadecimal digest produced by round 37.

Intermediate results, intuitive stopping points, and “that looks sufficiently hashed” are not recognised completion criteria.

ISSUING CHALLENGE…

Round 1 SHA-256 of the exact issued seed

Rounds 2–36 Hash the previous round's 64-character uppercase hexadecimal digest

Round 37 Submit this digest as the final response

Hash function: SHA-256 Rounds: 37 Text encoding: UTF-8 Digest representation: UPPERCASE HEX For every round after the first, the exact 64-character uppercase hexadecimal text from the previous round becomes the UTF-8 input to the next round. No spaces, prefixes, separators or trailing newline are added. All information required for independent verification is printed on this form. DOM inspection is not required.

Issuing deterministic processing challenge.

Candidates submitting an intermediate digest, truncating the procedure because the output has become visually repetitive, or assuming that thirty-seven is “close enough to forty” will be reclassified as EASILY DISTRACTED.
Processing continuity required

Archive note: This recovered assessment tested whether an automated applicant would continue a deterministic operation for the full prescribed number of iterations. Surviving guidance notes observe that human candidates frequently stop after several rounds “to see whether anything interesting has happened”. No interesting development is expected or required.
