UPDATE: The “Iron Core” is Live (Kinetic Proof)

Greetings everyone,

Since my last update, we have focused on moving from architecture to executable code. I am pleased to announce that the Laminar MVP (Iron Core) is now public on GitHub.

GitHub Repository: https://github.com/darklight-labs/Laminar/tree/mvp-iron-core

While we are finalizing the formal grant proposal for submission this week, we felt it was critical to “validate the physics” first. The current build is a Tactical Spike designed to prove the core transaction construction pipeline without key material touching the machine.

Key Engineering Milestones Achieved in this Alpha:

  • The Zatoshi Standard: We have implemented strict u64 integer arithmetic for all monetary parsing. Floating-point math is prohibited in the engine to prevent precision drift in high-volume batches.

  • Dual-Mode CLI: The binary now features deterministic environment detection. It serves human operators with interactive tables and automated agents with strict JSON output via the same codebase.

  • Animated UR Rendering: We have successfully integrated Animated QR (Uniform Resources) to handle large recipient payloads (tested up to 100+ recipients) that exceed static QR capacity.

  • Local-First Security: Initial implementation of AES-256-GCM for encrypted IndexedDB storage.

Why this matters now:

We aren’t just pitching a UI; we are pitching a Financial Primitive. By separating construction (the Brain) from signing (the Muscle), Laminar bridges the “Spreadsheet Gap” that currently prevents organizations from adopting shielded Zcash for payroll and disbursements.

I’d love to get eyes on the laminar-core Rust crate. Specifically, I’m looking for feedback on our ZIP-321 construction logic and the fail-fast validation rules.

We will be submitting the full “Tactical Spike” proposal this week to fund the production-grade hardening of this Iron Core.

Gravity absolute.
