Writing on cryptography, energy and verification

One substantial piece a month, on the two problems this practice exists for. The through-line is constrained optimisation and independent verifiability — the second being the part almost nobody builds.

In progress

Flexibility is becoming a traded commodity. Nobody can assay it.

Data centres are trading curtailment commitments for interconnection speed, and utilities are writing those commitments into large-load tariffs. Every flexibility claim is a counterfactual — what you would have used — and a counterfactual cannot be metered, only asserted by the party that benefits from it. Scheduling is the solved half. Verification is the half nobody is building.

Planned

What actually breaks when you swap a cryptographic primitive

The standards question is settled and the estate question is not. Key sizes your HSMs will not hold, counterparty integrations that quietly stop negotiating, certificate chains nobody has owned since 2019, and what larger signatures do to handshake latency on a payment path.

Field notes

Interactive

The exposure check

Mosca’s inequality with your own numbers in it. Three sliders, ninety seconds, no email — and it tells you whether the arithmetic has already turned against you.

Tool

Start a conversation

Tell me what you are dealing with

Three short steps, about ninety seconds. It means the first call opens on your situation rather than on introductions.

Which of these is closest?

This decides what I ask next, and what I read before we speak.

What happens next

A twenty-minute call on your situation, then a one-page written scope with a fixed price. Both free, and the scope is yours to take elsewhere.

Response time

Two working days, from me rather than an assistant.

Confidentiality

What you send stays between us. An NDA before the first call is fine, and I will sign yours rather than send mine.
