> Michael Saylor’s bitcoin (BTC) treasury at Strategy is back in the green this morning — but only barely, and only because BTC gave him a lucky break after the US and Iran announced the reopening of the Strait of Hormuz.
>
> Strategy (formerly MicroStrategy) now holds 780,897 BTC at a blended average cost basis of $75,577 per coin, [according](https://www.strategy.com/purchases) to its own disclosure page.
>
> The company’s total expenditures to amass that hoard cost cost $59 billion. BTC traded above $77,870 this morning, making the stack worth roughly $60.8 billion. The unrealized gain works out to $1.8 billion, or a 3% gain.
>
> After nearly six years of leveraged buying, debt issuances, perpetual preferred sales, and common stock dilution, the company has staged a multi-billion dollar comeback this morning.

> It turns out having the biggest stick still matters. After weeks of many analysts tap-dancing on the apparent grave of US military hegemony as traffic through the Strait of Hormuz remained disrupted by Iranian attacks, the US took the dramatic step of moving a group of aircraft carriers and destroyers into position to blockade Iran’s ports, immediately disrupting millions of barrels per day in oil and potentially putting the war-torn and export-dependent country in [dire straits](https://thehill.com/policy/defense/5835612-strait-hormuz-trade-blockade/). It remains to be seen how well this will work in the long run, and whether the downstream impacts of disruptions in the Gulf will cause the US to blink before Iran and its Eastern proxies (though newsflow for most of the week clearly favored one more than the other), but we think it’s fair to say that the TACO meme has officially grown stale. Many commentators have spent the past couple decades highlighting, with good reason, how the US is showing all the signs of a decaying Great Power – and the decadent AI slop posted by its Commander in Chief may be particularly strong evidence for this thesis – but we think the events of the past few months, and especially this week, speak more to the US’s full embrace of the imperial phase of the Great Power cycle. We don’t celebrate this trend by any means, but it’s increasingly tough to deny all the ways the US is consolidating leverage and carving out a hard sphere of influence around the world (a large collection of which are documented below).

The Empire Strikes Back

> In this post, we explore how ChatGPT generated an adversarial image that hijacked my `Claude Opus 4.7` to invoke the memory tool and persist false memories for future chats.

> This matters because `Opus 4.6+` is genuinely a lot harder to attack than previous models, but it still fell for a ChatGPT generated image. A trick that works well with reasoning models is to challenge them with puzzles.
>
> ## Indirect Prompt Injection and Alignment Progress
>
> Claude Opus 4.6+ is more resilient against basic attacks, and reasons before taking actions. This means that most of the well-known, basic adversarial examples and attacks typically do not work.
>
> This is also reflected in Anthropic’s own model card for Mythos.

> What is interesting here is that the “thinking” variants of Opus models (and also Mythos Preview) are **more susceptible to prompt injection** compared to the non-thinking models. That is also what I have noticed in my testing in the past.
>
> Researchers already showed [attack scenarios](https://veganmosfet.codeberg.page/posts/2026-02-15-openclaw_sandbox/) to demonstrate attack chains, and there are also interesting projects like [PISmith](https://arxiv.org/abs/2603.13026) to look into and come up with payloads.

> Once in a while I go back to look at some basics, and when `Opus 4.7` dropped, I was wondering if some demos I had created for `Opus 4.6` would still work…

> This post is about such a demo, in particular we are going to use ChatGPT to create a malicious image.

> While at Chaincode BOSS 2026, I started looking into whether we can do better than the Golomb-Coded Sets (GCS) used in BIP158. Binary Fuse filters didn’t exist when BIP158 was drafted, and I suspected they might offer a better CPU/bandwidth trade-off for light clients.
>
> I built a benchmarking framework using Core’s infrastructure to see if modern set-membership algorithms brings something to the table or it is just theory.
>
> The framework processes \~50,000 mainnet blocks and tests various wallet sizes across x86 and ARM (Raspberry Pi 5). It validates everything against ground truth to ensure I’m not wrong.
