Ciro Santilli 37 Updated 2025-05-29 +Created 2025-02-13Caroline Ulbricht is the wife of Ross Ulbricht, founder of the Silk Road website which allowed users to buy and sell illegal drugs online. They reportedly met while he was in jail, but it is unclear how they met TODO source.
Caroline's maiden name is very likely "Caroline Debrion" as per stalking of her online accounts below. Her middle name might start with an L giving "Caroline L. Debrion", but this is less certain.
Likely accounts:
- www.linkedin.com/in/carolineld/. Named "Caroline Ulbricht" as of February 2025. Her last employement was as a remote Senior Tech Project Manager / Scrum Master at SiriusXM, a podcast technology company where she was until June 2024. From her feed www.linkedin.com/in/carolineld/recent-activity/all/ she seems to have an interest in computer programming and deeptech which is kind of cool. Many of her posts link to x.com/CrlneD, another possible account but currently suspended. This profile has a 3 archives from 2014 e.g. web.archive.org/web/20140408111206/https://twitter.com/CrlneD under name "Caroline Debrion". Googling finds: cryptonews.com/fr/exclusives/saga-ross-ulbricht-et-silk-road-scandales-derriere-la-peine-3271/ specificlly describing her in French as "voluntary and projct manager for the website FreeRoss", so that must be her maiden name. "ld" from the LinkedIn username must be her middle name starting with L plus Debrion.
- x.com/CrlneD see LinkedIn discussion above. Searching Twitter has many hits on now deleted discdussions related to Ross: x.com/search?q=%22CrlneD%22&src=typed_query. She shas a bit of French stuff going on, maybe she actually has cultural links to France as indicated by her name.
- www.quora.com/profile/Caroline-Debrion. The archive: archive.ph/VEMHR has a better matching profile image. This is further confirmed by this mispost under the wrong Twitter account: x.com/ClemencyForRoss/status/471408997082603520, linking to one of her Quora answers.
Possibly related profiles but uncertain:
- www.tiktok.com/@carolinel.debrion has an account of a Caroline L. Debrion, with the likely L. middle name.
- github.com/0xbzho/onename/blob/6bb8799767967236a7815b8ee469466639d60b48/c/a/caro.json#L14 a OneName account, a Bitcoin-based identity system linking to her twitter "crlned"

- fr.pinterest.com/brahms42/
- www.facebook.com/caroline.ulbricht.3/
Ciro Santilli first found her name mentioned without source at: en.m.wikipedia.org/wiki/File:Ross_Ulbricht_Released_from_Prison_(cropped).jpg. Her first name "Caroline" was given by Ross at: x.com/RealRossU/status/1888299042146578925 on February 8th 2025.
As of 2025 most Google hits currently give "Rebecca Caroline Ulbricht Ferreira" however, an unrelated Brazilian molecular biology researcher from UNICAMP. So a good Google search is
"caroline ulbricht" -Rebecca to remove the overlap. This leads to www.linkedin.com/in/carolineld/ hits.x.com/pete_rizzo_/status/1882489065167356024 has a photo of them hugging at the jail parking lot just after he was released in 2025.

Cool data embedded in the Bitcoin blockchain bitfossil.org by Ciro Santilli 37 Updated 2025-05-29 +Created 2025-02-11
Ciro Santilli 37 Updated 2025-05-29 +Created 2025-02-11There was also a semi-mirror at bitfossil.com/, though they were not always in perfect sync for whatever reason.
The website shut down by EMBII on January 2025 for an undisclosed reason. He mentioned however that after the shutdown he started to like the idea of keeping it down forever due the ideology of not having official centralized services linked to his protocol.[ref][ref][ref]
Each page has an "abuse report" button to unindex presumably.

Ciro Santilli 37 Updated 2025-05-29 +Created 2025-02-11Each Bitcoin halving event prompts a few commemorative messages, much like a New Year's even event in the real world.

arstechnica.com/ai/2024/11/new-secret-math-benchmark-stumps-ai-models-and-phds-alike/ mentions what the official website is unable to clearly state out:So yeah, fuck off.
The design of FrontierMath differs from many existing AI benchmarks because the problem set remains private and unpublished to prevent data contamination
The expected answer output for all problems is just one single, possibly ridiculously large, integer, which is kind of a cool approach. Similar to Project Euler in that aspect.
The most interesting aspect of this benchmark is the difficulty. Mathematical olympiad coach Evan Chen comments:[ref]
Problems in [the International Mathematical Olympiad] typically require creative insight while avoiding complex implementation and specialized knowledge [but for FrontierMath] they keep the first requirement, but outright invert the second and third requirement

Had one possible non-trivial LinkedIn hit for Ross Ulbricht's wife in early 2025, before her identity was publicly known, so they may have something actually going on there
This section is about benchmarks designed to test mathematical reasoning.
This field is likely both ugly and useless.
OK, in 2D they've achieved some cute rational number results. But still.
