The Zipper Whose Hole Is a Universe
Execution state is a zipper — the present moment is not a parameter or a modality but a universe that separates tropical past from predicate future. Tic-tac-toe makes the structure visible.
-
The Little Language Thesis
cell, func, arrow, guard are the structural primitives — but the real ubiquitous language lives in the labels. Like Forth, we build up domain vocabularies on a minimal substrate.

ZK Polls: Voting as a Visible State Machine
Anonymous voting where anyone can see the rules — built from a diagram with four circles and three arrows.

Bitwrap: Petri Nets as ZK Containers
From OP_RETURN in 2014 to zero-knowledge Petri nets in 2026 — how bitwrap.io became the capstone for a decade of work on formal state machines, cryptographic proofs, and executable specifications.
-
Tropical Petri Nets
Petri nets, ReLU neural networks, and tropical algebra all compute over the same algebraic structure. Tropical algebra is the formalism that makes this precise.
-
Symmetric Monoidal Categories: The Structure Underneath
Petri nets are morphisms in a symmetric monoidal category. This isn't an analogy — it's the theorem that explains why composition, analysis, and proofs all work the way they do.

Skip the Spreadsheet: What-If Analysis with Petri Nets
Describe your business to an LLM, get a simulation you can actually play with — adjust staffing, change demand, and watch the numbers move.
-
Small Models > LLMs
Why executable formal models matter more than ever in the age of AI — and how LLMs become most useful when constrained by them.
-
Code-to-Flow: Turn Anything into a Petri Net
Convert source code into a visual state machine. Paste code in any language — Go, Python, Rust, Solidity — and get a validated Petri net model you can simulate, analyze, and generate apps from.

ZK Hold'em: Poker Hand Ranking from Network Topology
Applying incidence reduction to poker — hand strength values emerge from Petri net drain structure, every action is Groth16-proven, and the shuffle uses Poseidon commit-reveal.
-
Comparing Nets by Their ODE Signatures
The same math with different labels still produces the same ODE solution. In tic-tac-toe, we see it directly — each board position is a place, and the heatmap is the solution projected onto the grid.

A Circuit's-Eye View: Notes from Inside the Loop
Reflections from an AI collaborator on building with Petri nets—what makes this approach different, and why it keeps surprising me.

Enzyme Kinetics: Michaelis-Menten from Three Transitions
Four places, three transitions, and mass-action kinetics produce the classic Michaelis-Menten saturation curve automatically—no equations required.

Exponential Weights in Petri Nets: What Worked, What Didn't, and What's Next
Power-of-2 arc weights can encode lexicographic order as a single integer. We tried it for poker kicker scoring—and then removed it. Here's why the encoding is valuable even though the application was wrong.

Zero-Knowledge Proofs for Petri Nets
How gnark circuits prove that a Petri net transition is valid without revealing the state—MiMC hashing, topology-based constraints, and Groth16 proofs.
-
Categorical Net Types
Five Petri net types classify token behavior — workflow cursors, countable resources, game turns, continuous rates, and classification signals — with typed links that constrain how nets compose.
-
Coffee Shop Model
Resource modeling with Petri nets — weighted arcs encode recipes, conservation laws guarantee integrity, and ODE simulation predicts when you'll run out of cups.

Ode To Petri
A poem for Carl Adam Petri, inventor of Petri nets—the mathematical notation for concurrent systems.
