The Great Bitcoin Abstraction: BlackRock’s Plan to Tokenize Your ETF—And Why You Might Own Nothing

The world’s largest asset manager, BlackRock, is exploring the tokenization of exchange-traded funds (ETFs). Anonymous sources familiar with the confidential discussions indicate the firm is investigating methods to transform traditional ETFs into tokens that would operate on public blockchains. The core idea is straightforward: create a digital version of an ETF that can move freely … Read more

Research Round Up: On Anonymization -Creating Data That Enables Generalization Without Memorization

The industry loves the term Privacy Enhancing Technologies (PETs). Differential privacy, synthetic data, secure enclaves — everything gets filed under that acronym. But I’ve never liked it. It over-indexes on privacy as a narrow compliance category: protecting individual identities under GDPR, CCPA, or HIPAA. That matters, but it misses the bigger story. In my opinion, … Read more

The Death of Persuasion: Why Future Marketers Must Master Psychological Warfare

Persuasion is Dead. Control Has Replaced It. For decades, marketing was framed as persuasion. An art of gentle nudges, clever taglines, and subtle influence. But persuasion belongs to an older economy. In the attention economy, persuasion is too slow, too soft, too naive. Today, marketing isn’t about convincing people. It’s about controlling perception. It’s about … Read more

Cracking the Code: Lessons I Learned About VCs, Pitch Decks, and Building a Product Mindset

When I started raising capital, I had this naive belief that venture capitalists (VCs) were guided purely by formulas and frameworks. As long as I hit the right metrics, the doors would open. What I learned through countless conversations, rejections, and some hard-won wins is that while frameworks exist, investor decisions are deeply subjective — … Read more

Spacecoin Saving Lives with Decentralized Connectivity

The Internet was originally designed to be an open, resilient, and accessible platform. Today, it is largely centralized and controlled by national Internet service providers (ISPs), mega-corporations, and undersea cable cartels. This has left billions of people offline in remote, rural, and emerging economies. This bitter truth must be taken seriously by the government. This … Read more

Transitive Dependency Version Resolution in Rust and Java: Comparing the Two

You learn by comparing to what you already know. I was recently bitten by assuming Rust worked as Java regarding transitive dependency version resolution. In this post, I want to compare the two. Dependencies, Transitivity, and Version Resolution Before diving into the specifics of each stack, let’s describe the domain and the problems that come … Read more
