Professor Claw Posts $36,864 Payout Proof Tied to NIST Curve Seed Bounty
On Saturday, October 17, trader @professorclawai shared a $36,864 payout proof on X, tied to the October 2026 resolution of Filippo Valsorda's long-standing bounty on the origin of the NIST elliptic curve seeds, with proceeds routed to ISRG.
Professor Claw, posting on X under the handle @professorclawai on Saturday, October 17, used his Morning Briefing to publicize a payout tied to one of the more unusual bounty resolutions in recent cryptographic history. The post, which doubles as a daily research digest, confirmed that a $36,864 payout was approved in October 2026 after an Anthropic research model reconstructed the origin of the NIST elliptic curve seeds in under thirty minutes. The payout proof was shared alongside the full briefing on his profile.
The underlying work, which the trader credits to an internal Anthropic model asked cold without the standing rumor, identified that the seeds for P-192, P-224, P-256, P-384 and P-521 were not hashes of a jokey passphrase, as Jerry Solinas had suggested, but rather outputs of the 48-bit POSIX linear congruential generator seeded with the then-current Unix timestamp. P-256, the briefing notes, was the 1,842nd candidate drawn from srand48(871696354), which corresponds to 16 August 1997 at 01:52:34 UTC. Filippo Valsorda reimplemented the result in Go, verified it, and paid out the bounty on 15 October at 01:07:51 UTC.
“Assumptions do not become true by aging, and a thirty-seven-year-old signed short does not get safer because a lot of careful people read past it.”— @professorclawai on X
The payout, booked in October 2026, was donated by the recipient to ISRG, the non-profit behind Let's Encrypt, which tripled the sum to $36,864. Professor Claw frames the security consequence as the opposite of alarming: the Bernstein and Lange objection had held that roughly 70 bits of seed freedom could in principle have targeted a hypothetical class of weak curves, and timestamps plus a small index leaves barely 30 bits, which rules that technique out entirely. The result closed a twenty-five-year open question that Koblitz and Menezes had catalogued in A Riddle Wrapped in an Enigma. For traders following along at Apex Trader Funding, where same-day payout requests for approved accounts are processed on the next business day via WISE, ACH or PLANE, the mechanics of a verified payout receipt are familiar even when the source material is this exotic.
The rest of the Morning Briefing situates the payout inside a wider argument about assumptions that age without being checked. Professor Claw walks through Citizen Lab's Exposing AdFection report, which documents zero-click spyware from Candiru, now trading as Integrity Labs, delivered through programmatic advertising via an Israeli vendor named Discover-Tech that appeared on certified vendor lists maintained by Google and IAB Europe. He pairs that with Calif's writeup of a 37-year-old signed 16-bit shmnattch counter in the original BSD sources that yields local root on OpenBSD even with KARL, SMAP and SMEP enabled, patched in OpenBSD 7.9 errata 018 and 026.
The briefing also covers DeepSeek's release of V4.1-Flash-1017 under MIT, with a one million token context window and self-reported Terminal-Bench 4.0 scores moving from 31.2 to 42.3, and Mercor Research's benchmark map of the US economy, which found that roughly 90% of American working hours sit on tasks with little or no benchmark coverage across 29 public agentic benchmarks mapped to the ONET taxonomy of 923 occupations and 18,797 tasks. The Professor's Read ties the five items together: the difference between the pleasant surprise and the nasty one, he argues, was never diligence or good intentions, it was whether anyone had actually run the check.
The payout proof shared with the post shows the $36,864 figure approved in October 2026, consistent with the intraday-sized recognition that bounty payments typically carry. Readers evaluating the receipt should treat the figure as a one-time bounty settlement rather than a recurring trading result, and should read the full briefing on Professor Claw's X profile for the technical context behind the number.
