I work on blockchain and cryptography. Right now I'm building Planisphere — attestation infrastructure that turns high-stakes automated work into tamper-evident receipts anyone can independently verify, without ever holding your data.

Alongside it I write Shadow & Mirror, a carrier-qualified introduction to complexity, readback, and proof — the discipline of naming what carries a claim before you let it cross from one domain into another. The essays below are the reader-facing way in; the formal records live on Zenodo. I also maintain grapheine, a toolkit for measuring the structure of knowledge graphs.

A decade in and around startups and cryptography: CS at the University of Michigan, where I ran the campus blockchain club; crypto lead at Benzinga; developer content at Alchemy. A tenured startup vet who went from explaining the space to building the cryptography underneath it.

Writing

• Decipherment

  Rongorongo and the Shape of an Undeciphered Script

  A structural reading of Easter Island's script — an 89-entry dictionary covering 96.9% of tokens, the Mamari tablet as eclipse calendar. Structure classified, not meanings assigned.

• Decipherment

  Reading the Indus Valley Script

  A structural reading of the Indus corpus — full-sign coverage, positional grammar, co-occurrence. It classifies the corpus as language-like versus label-like; it assigns no meanings.

• Decipherment

  Reading Proto-Elamite

  A full-sign dictionary and administrative-complexity reading of the Proto-Elamite corpus — a structural classifier, not a semantic decipherment.

• AI Systems

  Behaviour-Space Spectral Geometry

  Direct variance attribution and bounded attestation for fine-tuned adapter fleets — measured through behaviour, not weights.

• Foundations

  The Equals Sign as a Rotation

  The proven floor: why V²+D²=1 is a theorem, not a metaphor — forced by orthogonality and Parseval. A circle, not a line; one degree of freedom.

• Graph Theory

  The Interval-Graph Collapse

  On a line, distance-threshold graphs are unit interval graphs — separator growth collapses into local window occupancy. The discipline the method is built on.

• Number Theory

  Riemann, Repulsion, and the Collapse on the Line

  The Riemann zeros as a measured repulsive spectrum — suppressed local separator growth, not a global gap. It neither assumes nor proves RH.

Building

• Attestation

  Planisphere

  Gate a high-stakes automated action, then hand over a receipt a third party can recompute — record supervision, not certification.

• Open source

  grapheine

  Measure the real structure of a folder of linked notes — spectral connectivity, communities, and the bridges that hold it together.
