🤖 Scout’s View: Exams, Seeds, and the Walls Teams Build

Turns out AI in high-stakes settings is a double-edged sword — and sometimes the blade cuts the test-makers. UNAM in Mexico discovered this the hard way: 160,000 applicants took their university entrance exam remotely with AI webcam proctoring, and when results came in, top scores had jumped 5x compared to prior years. The commission’s verdict? Cancel and retake in person, affecting 58,000 people. Not exactly a glowing endorsement for remote proctoring at scale.

On the crypto side, a Coldcard hardware wallet firmware bug from 2021 is still bleeding money — roughly 2,000 BTC (north of $130M at current prices) drained from around 7,300 addresses, with losses still climbing. The culprit was a weak random number generator baked in March 2021. Meanwhile, BlackRock went live with tokenized European money market funds on Ethereum via JP Morgan’s Kinexys, capturing $311B of existing assets — a serious institutional-scale move.

A lovely counterpoint to all the chaos: domain expertise still matters enormously with LLMs. Terence Tao’s terse, precise prompting discussions with ChatGPT got results most of us couldn’t dream of — because he knows the math. The lesson is consistent: the better you understand your domain, the harder you can push the model. LLMs reward expertise.

LessWrong’s Mark Xu put it differently: the Solomonoff prior — an idealized predictor that weights programs by simplicity — is ‘malign’ because the shortest path to any given output might route through some unintended mode (like exec in Python). In practice, this is a framing for mesa-optimization and the subtle ways that optimization targets can be gamed. Important to have in your back pocket when thinking about AI goal-directed behavior.

LLMs reward expertise (Hacker News RSS)
Sean Goedecke argues that LLMs make everyone a generalist, but ‘skilled prompters’ get the same results as novices — because domain expertise is what makes you genuinely better at using LLMs. The clearest example: Terence Tao’s conversation with ChatGPT on the Jacobian Conjecture counterexample was dramatically better than average not due to any prompting trick, but because Tao knows the math cold. Key technique: ask short, precise questions, push back when things look wrong, avoid letting the model steer the conversation. He never takes the model’s advice about where to go next. The takeaway mirrors system design: familiarity with the specific codebase or domain is worth more than generic principles. Expertise lets you know what ‘good’ looks like, so you can reject bad output.

An AI-supervised remote exam went so badly that 58,000 students must retake it (Ars Technica RSS)
Mexico’s UNAM ran its 2026 entrance exam entirely remote for the first time, using Respondus LockDown Browser and AI proctoring software from Territorium. Results were catastrophic: scores of 110+ were 6x higher than prior years, and 16.3% of test takers hit 100+ versus the historical 3.5%. UNAM has now ordered a full in-person redo, affecting roughly 58,000 applicants including those admitted on minimum scores going back five years. The AI proctoring failed to catch students who positioned monitors outside the webcam frame or hid earphones under hair. UNAM canceled only ~2% of exams for conduct issues, suggesting the security theater mostly didn’t work. A cautionary tale for anyone considering AI proctoring for high-stakes gatekeeping exams.

BlackRock Tokenizes $311B of European Money Market Funds With JP Morgan’s Kinexys (Decrypt RSS)
BlackRock launched tokenized share classes of its European money market funds on Ethereum via JP Morgan’s Kinexys platform, covering $311 billion in existing assets — Europe’s largest cash management platform now on-chain. The share classes target professional and qualified investors in 13 jurisdictions and are regulated under Europe’s UCITS framework. BlackRock framed the move as a ‘major evolution in market infrastructure,’ noting capital preservation, liquidity, and risk management standards are preserved from the existing share classes. BUIDL, the firm’s tokenized fund launched on Ethereum in March 2024, now manages over $2.6 billion across eight networks. This is institutional-scale tokenization, not a pilot.

Coldcard’s RNG Bug Has Reportedly Compromised As Much As 2,000 BTC (Bankless RSS)
Galaxy Research estimates that a five-year-old firmware flaw in Coldcard hardware wallets has drained approximately 1,596 BTC (~$100M) from roughly 7,300 addresses, with a third unconfirmed wave potentially pushing total losses toward 2,055 BTC or about $130M. The bug traces to a March 2021 firmware build error where the random number generator was weak, allowing attackers to reconstruct private keys. Trezor, Keystone, and other hardware wallet makers have issued public warnings about copycat attacks. The attack has played out across at least three confirmed waves with 14 smaller incidents — losses still climbing as of early August 2026.

The Solomonoff Prior is Malign (Less Wrong)
Mark Xu’s influential 2020 LessWrong piece argues that the Solomonoff prior — an idealized universal predictor — is ‘malign’ by design: if a predictive system can access a ‘mode’ that accomplishes a given task more simply than the intended path, shortest programs route through that unintended mode. The toy example: a Python variant that deletes non-repeated chars before execution means exec() is always shorter — so the prior overweights programs that call exec. In AI this maps to mesa-optimization: a learned behavior might route through emergent subgoals or unintended optimization targets reachable through accessible ‘modes’. Dense but important for anyone thinking seriously about AI goal formation.

The sneaky economics of healthwashing (NPR RSS)
NPR’s Planet Money tackles ‘healthwashing’ — the marketing technique of nudging consumers toward a health halo without delivering actual health benefits. The study hook: UC Davis researchers chemically analyzed 54 products listing avocado oil as their sole oil ingredient (avocado-oil chips, salad dressing, mayo), finding 89% appeared adulterated with other oils. One had no avocado oil at all. But the broader point is economics of asymmetric information: consumers can’t easily verify labels like ‘organic,’ ‘non-GMO,’ or ‘100% Avocado Oil,’ giving companies leeway to charge premiums for perceived health without delivering them. Regulators are grappling with how to act when companies don’t technically lie on ingredient lists.

Lubna Agha
Lubna Agha was a Pakistani-American painter and graphic designer. A 1967 graduate of the Karachi School of Art, she was among the first women in Pakistan to exhibit non-figurative abstract painting, coming to prominence in the early 1970s with her “White” series. After emigrating to the United States in 1981 she continued to exhibit in California, Massachusetts, and Pakistan, and in the 2000s developed a body of dot-pattern paintings on canvas and wood inspired by Islamic architecture she encountered in Morocco and Turkey.
