ZenAI v4 — ZenLoop as Pair Programming: Adversarial by Construction
v3 introduced the ZenLoop — two AI agents under separate roles. v4 makes them pair programmers: asymmetric in what they own, equal in authority, structurally challenged in both directions. Four mechanisms enforce the adversarial pressure that v3 left to culture. The loop now runs at AI speed inside the direction I set.
ZenAI v3 — The ZenLoop: Agent-to-Agent Feedback and Verification
AI coding agents are strong locally but weak at resisting their own momentum. They narrate partial progress as completion, and shortcuts drift into foundations. ZenAI v3 introduces the ZenLoop — two independent agents, Cody and Zain, on different model families, applying verification pressure through a structured, automated handoff protocol. Don’t Trust, Verify — applied to AI.
ZenAI Framework v2: What Survived Six Months of Real-World AI-Assisted Development
AI coding assistants excel within a single session, but real software is built across weeks of evolving decisions and context. ZenAI Framework v2 emerges from six months of real-world experimentation, introducing a simpler, structured approach to continuity, independent verification, and workflow discipline for building production systems—not just generating code.
Barqly Vault: Technical Deep Dive (Part 2)
This post walks through the technical architecture behind Barqly Vault, including its threat model, envelope encryption design, multi-key access model, and hardware-backed key integration, and examines the tradeoffs and operational decisions that influence recovery and failure scenarios.
Barqly Vault: Design, Journey, and a Security‑First Mindset (Part 1)
Barqly Vault is an offline-first, open-source desktop application for encrypting, recovering, and securely sharing sensitive data. Originally built to protect Bitcoin custody metadata, it has evolved into a general-purpose tool focused on recovery, operational safety, and clear security tradeoffs—designed to remain usable as devices, keys, and software change over time.
ZenAI Programming Rituals: Turning Chaos into Flow through Context Engineering
ZenAI Programming Rituals grew out of the same mindset that shaped Barqly Vault: eliminate repetition, respect context, and build with integrity. In this post, I share how I structured AI personas, layered context engineering, and set protocols for trust and verification — turning chaotic sessions into a more focused flow.
From Lazy Programmer to ZenAI: How I Built Barqly Vault with AI
From product owner to architect, programmer, tester, and security engineer — I partnered with AI to play all these roles while building Barqly Vault, a simple open-source desktop app to encrypt script trees, output descriptors, and sensitive documents. This post reflects on that journey and the ZenAI Programming Ritual framework that guided it.
Multisig for Individuals: A Real-World Guide to Secure Your Bitcoin
This hands-on guide walks through a complete 2-of-3 Bitcoin multisig setup for an individual client—from wallet design to backups and inheritance. It’s a field-tested, zero-trust protocol for self-sovereign custody that blends technical rigor with practical recovery. A must-read for Bitcoiners serious about hodling their own keys long-term.
Cloudless Recovery: Securing Your Bitcoin Seed with YubiKey’s Large Blob Storage
What if you could recover your Bitcoin without trusting the cloud—or even writing down your seed? This post explores a hands-on prototype using YubiKey’s large blob storage to secure your BIP39 seed, offering a hardware-backed, phishing-resistant recovery path that balances usability with sovereignty. A new take on cool-key self-custody.
Defending Bitcoin’s 80-Byte OP_RETURN Limit: Preserving Purpose Over Perks
Bitcoin’s 80-byte OP_RETURN limit is a vital guardrail, ensuring blockspace remains focused on secure monetary transactions rather than a data dumping ground. Removing it risks blockchain bloat, legal liabilities, and ideological drift. Join us in defending Bitcoin’s core ethos: lean, permissionless, and robust digital cash. Run principled node software today.
