Epistemic status: speculative proposal. I am an electrical engineer and independent researcher, not an economist or chemist.
AI disclosure: English is not my native language — I am Brazilian and write primarily in Portuguese. I used Claude (Anthropic) in two distinct ways: (1) as a thinking partner to develop, stress-test, and structure these ideas through dialogue; and (2) to help express them in English with the precision the ideas require. The reasoning, conclusions, and original intuitions are my own. I am disclosing both uses explicitly because the LessWrong policy on AI-assisted writing deserves a direct answer, not a footnote.
I'm posting here to find serious criticism before the ideas calcify.
The coordination failure I'm trying to solve
A tonne of single-use plastic packaging can be worth more than a hectare of standing forest. A poorly engineered building that wastes twice the material costs roughly the same as a well-engineered one. These are not market inefficiencies in the standard sense — they are a structural absence. The thermodynamic cost of making things exist is simply not represented in price signals at all.
This is a classic Moloch problem: no individual actor has an incentive to price in physical reality, so no one does, and the collective result is a civilization that systematically destroys more than it needs to.
The standard proposed fixes are regulatory (carbon taxes, environmental law) or social (ESG, conscious consumption). I'm skeptical these are sufficient because they are imposed on top of a value system that doesn't natively account for physical cost — they fight the underlying incentive structure rather than changing it.
I want to ask a more fundamental question: could we design a value system where intrinsic physical cost is the anchor, rather than an afterthought?
The core idea
I propose a construct I'm calling a Physical State Token (PST) — a cryptographic record whose identity and value emerge from direct physical measurements of the object it represents.
The key insight is that the isotopic composition of materials — the ratio of nuclear variants of elements — is a physical fingerprint that reflects billions of years of geological history. Copper from Chilean deposits has a measurably different lead isotope ratio than copper from the Congo. This cannot be falsified without altering the material itself. No document, declaration, or social convention can substitute for it.
A PST would encode three things:
1. An isotopic fingerprint, derived from mass spectrometry, anchored to geographically-determined primary sources. The token's identifier is a hash of this fingerprint — not assigned by any authority, but emerging from the physics of the object.
2. A provenance graph, tracking every transformation: mining → smelting → manufacturing → recycling. When materials combine, their PST fingerprints combine predictably. Any deviation between predicted and measured composition is a quantifiable fraud signal — you don't need to know where the fraudulent material came from, only that it's there.
3. An environmental liability ledger, accounting for mass losses during the object's lifetime. A plastic that sheds microparticles at 0.1% mass/year accumulates a compounding liability. This makes environmental dispersion economically visible for the first time.
The value of a PST is not a scalar — it's a vector (thermodynamic cost, provenance integrity, environmental liability). This is more honest than a single price, but requires an agreed weighting function to convert to scalar for exchange. That weighting function is explicitly political and governable, rather than hidden inside opaque market dynamics.
Why this is different from what already exists
This isn't the EU Digital Product Passport (which relies on manufacturer declaration, no physical verification). It isn't Bitcoin (which anchors value to computation, producing nothing except the proof of expenditure). It isn't NFTs (which failed because owning the token didn't confer control over the object and didn't prevent copying).
The critical difference: a PST can be independently verified against physical reality at any point in the provenance chain. A blockchain guarantees internal consistency. A PST provenance graph guarantees consistency with the physical world.

The hard problems I haven't solved
I want to be direct about where this breaks down, because I'm genuinely uncertain:
The physical oracle problem. Someone has to translate a physical measurement into a cryptographic attestation. Today, this requires trusting a human in the loop. The theoretical solution is a TEE-integrated analytical instrument (a mass spectrometer with a tamper-evident hardware enclave that signs its own output), but no such device exists commercially. This is the most critical gap between the proposal and reality.
Bootstrap centralization. Registering primary sources (mines, forests) requires initial trusted measurements. This creates a centralization point at the moment the system is most vulnerable. Multi-laboratory attestation with open publication is the mitigation I can see, but I'm not confident it's sufficient.
Reprocessing erases history. Melted and re-alloyed metals lose their source-specific signature. The system handles this — the mixture's PST reflects the wider uncertainty — but heavily recycled materials have noisier value envelopes. I don't know if this degrades the system's usefulness for major recycled material flows.
Biological materials are harder. The isotopic variability of biological materials is continuous and seasonal rather than geographically discrete. DNA barcoding and protein fingerprinting add dimensions, but the uncertainty is wider. I'd estimate the system would work well for crystalline minerals and poorly for, say, cotton.
The weighting function is political. Deciding how much thermodynamic cost is worth relative to environmental liability is not a technical question — it's a values question. I've argued this is better than hiding it inside market dynamics, but I might be underestimating the coordination difficulty of agreeing on weights globally.
Why I think this is worth taking seriously despite the problems
The measurement costs are the most common objection I anticipate. Isotope ratio mass spectrometry is expensive per sample today. But:
GPS was military-grade and expensive; now it's free and ubiquitous
DNA sequencing was billions per genome in 2000; now it's hundreds of dollars
Portable Raman spectrometers already exist for thousands of dollars
The economic value created by PST certification would generate strong incentives for cheaper instruments
More importantly: the system doesn't need to cover everything to be useful. Partial coverage of high-impact material flows — industrial metals, plastics, timber — would already represent a qualitative change from zero physical verification.
What I'm actually asking for
I'm not confident this proposal is correct. I'm confident the problem it targets is real and under addressed.
Specifically, I'd welcome pushback on:
Whether isotopic fingerprinting is as robust as I believe for the primary source registry use case
Whether the fraud-detection property of mixture predictability actually holds under realistic industrial conditions
Whether there's existing literature I'm missing that either solves this or shows it's intractable
Whether the weighting function problem is actually harder than I'm treating it
