Privacy

These articles examine privacy not only as a technical concern but also as an expression of sovereignty, the same principle that runs through Bitcoin and inner work. They explore what it actually means to own your data, your communications, and your digital presence in a system designed to extract and monetise both. The surveillance economy and the fiat economy share the same architecture: Centralised control, manufactured dependency, and the quiet erosion of autonomy. The articles here cover the tools, the reasoning, and the deeper question of why privacy matters to anyone who is serious about living outside that architecture.

How to Verify APK Authenticity: Complete Guide for GrapheneOS and Google Android Users

Last Updated on: June 2, 2026

GrapheneOS users can verify APKs entirely on-device through Accrescent and AppVerifier; Google Android users need a computer running apksigner before the APK ever touches the phone. Both paths arrive at the same cryptographic guarantee: the app came from the real developer and has not been altered. For anyone sideloading from decentralized sources like Zap Store, this verification step is the difference between trusting the software you run and hoping for the best.

Nostr Attack Vectors Every User Should Know About & How to Mitigate Them

Published on: May 29, 2026

Many Nostr users assume that because it’s decentralized and uses cryptographic keys instead of passwords, it’s inherently secure and private. That assumption is incorrect in several important ways, but that doesn’t mean we cannot engage with Nostr in a secure and private manner. This article covers attack vectors and how to mitigate them. I cover each point in plain language for regular users who aren’t reading the GitHub threads where developers are discussing these questions.

I’ve never had sponsors and I don’t run ads. My content is fully self-funded and supported by readers like you.

This is value for value in practice; the peer-to-peer, no-middleman principle I write about in my book.
