Exhibit 1 · Overview
The decision at hand, the three site hypotheses, and what this study is — and is not. Two minutes of reading to place the whole before the detail.
Two futures for the
PSG grand stadium
— proving the four theorems, so the project succeeds on its own terms
Poissy, Massy or the Parc des Princes: Paris Saint-Germain decides in autumn 2026. Whichever hypothesis wins, a 60,000–90,000-seat district will ask its territory the same question: how do you prove your promises — of jobs, of local benefit, of honest tickets? This study compares, pillar by pillar, the two possible futures. Tap a pillar to open its register.
Poissy
The Stellantis industrial site, next to the PSG Campus. Genuine local support; reopening the Poissy–Quai-Talbot rail station is under study.
Massy
The La Tuilerie zone, a retail park 2 km from the TGV station. Local opposition, disputed job promises, and a referendum pledged by the mayor.
Parc des Princes
A "genuine option" once more since the election of Emmanuel Grégoire, with dialogue reopened on sale or expansion of the existing ground.
What we mean by an Exemplar Use-Case Study
A working document addressed to the people responsible for this project, and to those following its progress. It is built on the public record — every date, figure and quotation sourced — and on the published ROCKR architecture, with the two kinds of claim visually separated throughout. Its heart is a set of interactive comparisons: for each pillar of the project's promise, the future without verified participation beside the future with it, on concrete metrics. This is not a sales document: it is written to be corrected and improved by the people who know the project best, in the open, with anyone welcome to follow. ROCKR is independent of the project and has no affiliation with its promoters or partners; the “With ROCKR” scenarios are our proposal, built on the published ROCKR architecture, and nothing here should be read as implying the project's engagement or endorsement.
Exhibit 2 · Chronology
From Qatar 2022 to the autumn 2026 decision: every step dated and sourced, so the reader can check the sequence rather than take our word for it.
From Qatar 2022 to the autumn decision
Every date below is public. The window that matters opens now.
Leaving the Parc is first floated
Mid-World Cup, club president Nasser Al-Khelaïfi openly raises departing the Parc des Princes, judged undersized at 48,000 seats for the club's ambitions.1
Two finalists
Ten days after the club's first Champions League title, PSG shortlists two sites for a 60,000–90,000-seat stadium: the Stellantis plant at Poissy and the La Tuilerie zone at Massy. Montigny-le-Bretonneux, Ris-Orangis and Aulnay-sous-Bois are eliminated.2
Steering committees — and a first democratic snag
The club holds steering committees with Poissy then Massy for its stadium-and-district "PSG Land" project. In Massy, the mayor promises a local referendum if re-elected — a move received "with a certain perplexity" on the PSG side.3
Third steering committee: three comparable hypotheses
The club confirms it wants "comparable and sufficiently consolidated elements by the autumn to allow an informed decision" on Poissy, Massy — and the Parc des Princes, restored to the study after the election of Paris's new mayor.4,5
The decision — then the public process
A facility of this scale will then pass through France's standard planning stages — concertation préalable, then a formal public inquiry — on the chosen site. That is where promises will have to become proof.
Exhibit 3 · Trust
The underlying problem: promises no one can verify, and a law that already exists. It is the proof that is missing — not the right.
A trust deficit meets an unenforced law
Promises nobody can verify
In Massy, Green and left-wing councillors call the project's job promises "overvalued" and object to handing a privately run scheme a space shaped by years of public planning. The dispute turns on exactly what no major project can yet produce: proof, year after year, of its local benefits.6
The law already exists — the proof is what's missing
Habitual ticket resale without the organiser's authorisation has been a criminal offence in France since the law of 12 March 2012 (article 313-6-2 of the penal code: a €15,000 fine, rising to €30,000 and a year in prison for repeat offences), and fake tickets constitute fraud (five years, €375,000). Yet illicit-resale litigation rose 200% between 2018 and 2022, and on 28 May 2022 the Champions League final at the Stade de France descended into chaos — thousands of genuine ticket-holders trapped at locked gates, spectator trust shattered. France's Sénat was still debating it in March 2025: "our legislative arsenal is not sufficient."7,8,9
What "with ROCKR" means: deliver the legacy, then prove it
The councillors' objection is a fair one: today, these promises cannot be verified. The "with" answer is a chain — and ticket fraud is only its front door. First, credibility: the four theorems — machine-verified, an asset never sold to the public, no speculative path, a single issuance tap — are what distinguish this digital utility asset in a crypto landscape that has earned no one's trust. Then, liquidity: equal weekly auction credits for every verified resident, and grants issued only against authenticated presence, fund the district's everyday programme — the training mornings, the arts evenings, the neighbourhood Thursdays that legacy targets are actually made of. Finally, proof: the same verification makes every delivered outcome auditable, year after year. Deliver the legacy, and prove it delivered. (WP 8.1, §6.5, §7.1.2 · The £150 Ticket Storyboard — TBTL · annex "Why a Coin at All?")
French finance is running on one of two legs
While the club studies its three hypotheses, the French financial centre is moving at speed on the money leg of settlement: BNP Paribas issued tokenised money-market fund shares on a public blockchain in 2026 through its AssetFoundry platform, joined the Canton Network alongside HSBC, and its Securities Services business is working toward atomic settlement — the security and the cash exchanged as a single, indivisible unit; the Banque de France is running a first real-life pilot of tokenised wholesale central-bank money in 202612,13,14,15. None of these institutions is, to our knowledge, engaged in the stadium project — but the club has said it needs to understand the infrastructure-financing modalities before finalising its evaluations5, and that conversation will take place in this landscape. Everything tokenised in it is the money. The entitlement leg — the ticket, the verified person at the turnstile, the participation that actually took place — today has no proven equivalent. The four theorems are precisely that missing leg: the day French settlement becomes atomic, the district that can prove who passed through settles both legs of the same transaction — and will be the first in the world able to demonstrate it.
Exhibit 4 · Pillars
The heart of the study. Six pillars — Education, the Arts, Community, Sport, High-street Retail, Health — and for each a register comparing, metric by metric, the future without verified participation and the future with it. Tap a card to open its register; highlighted terms explain themselves in one tap.
Six pillars, two futures
The stadium and its tickets
60,000 to 90,000 seats — and the memory of 28 May 2022, when ticketing fraud humiliated France before the world.
The shops around the stadium
A repurposed retail park in Massy, an industrial brownfield in Poissy: either way, shopkeepers who must become more than a point of sale.
Skills for the build and the district
Thousands of promised jobs presuppose training, certification, and proofs of learning worthy of trust.
Programming a district, every day
A "PSG Land" that lives beyond matchdays is a cultural promise. Someone still has to fund, book and pay for every experience.
Benefits that can be audited
A referendum is won with proof, not projections. How will a territory know, in ten years, whether the promises were kept?
Participation as prevention
Sport, social connection, associative life: a district's health dividend — provided residents genuinely take part.
Exhibit 5 · People
Who decides, and when: the people responsible, the doors about to open — public consultation, then formal review — and what we ask. Nothing that assumes a technology risk.
The people responsible
| Actor | Role | Relevant comments / actions |
|---|---|---|
| Nasser Al-Khelaïfi | President, Paris Saint-Germain | Has carried the project since December 2022; has promised "responsibility, transparency and rigour" for an informed decision in the autumn.1,4 |
| Nicolas Samsoen | Mayor of Massy (UDI) | Has pledged a local referendum on the project — the first great French stadium whose public acceptance would be put to a vote.3 |
| Karl Olive | Member of Parliament, Yvelines (Poissy) | Political champion of the Stellantis site, where the club has already built its Campus.2 |
| Emmanuel Grégoire | Mayor of Paris | His election has warmed the dialogue on the Parc des Princes, once again a "genuine option."5 |
| The steering committees | Club + territorial partners | The forum where "two options developed with ambition and seriousness" are built — and where a proof infrastructure can be put on the agenda.4 |
| The Sénat | Legislator | Ongoing debate on reforming art. 313-6-2 and on licensed resale platforms: verifiable ticketing is a live parliamentary subject.8,9 |
The door about to open
The club's decision is expected in autumn 2026. On the chosen site there will follow the concertation préalable and then the public inquiry — official registers through which any organisation, including ROCKR Proof Labs and ROCKR Preuves, can enter a submission on verified-participation infrastructure into the record. In Massy, a referendum would make proof of local benefit the central argument of the campaign.
The timing — and the ask
Nothing in this study asks the project to take a technology risk. A grand stadium delivered in the early 2030s will open years after ROCKR's TestNet and then MainNet programme — funded by public research grants — has been completed, launched and publicly tested; no partner will ever be offered a technology that has not already proven itself, RUIPA included. The dependency runs the other way: the "with" column will only exist in 2030 if the four theorems are proven now, inside the current research window. That is the one thing the people in the table above can influence today, and it costs a single gesture: joining ROCKR Preuves. A symbolic membership — no meaningful money, no procurement, no commitment to adopt — that publicly signals the territory wants the proof to exist by the time it needs it.

Exhibit 7 · Philosophy
Optional altitude: the philosophical case for proofs — a five-move story from a black hole to a turnstile, honest about which moves are physics and which are hypothesis.
From black holes to ROCKR
It begins at a black holePenrose, 1965 — the point where physics stops
In 1965 Roger Penrose proved that when a massive star collapses, it must form a singularity — a point where gravity becomes infinite and the laws of physics simply stop working. The work earned him the 2020 Nobel Prize in Physics, and it left a question that shaped the rest of his career: what kind of theory could describe reality where our best equations fail? His answer, pursued over decades, was geometric — beneath space and time there is structure, and understanding it would take more than computation.
The mind that steps outside the rulesGödel's theorem — and a proposal Penrose himself marks as speculative
Kurt Gödel proved that any sufficiently rich mathematical system contains truths that cannot be proven by following that system's own rules. Yet human mathematicians can step outside the rules and simply see that those statements are true. Penrose drew a bold conclusion: human understanding is not, at bottom, rule-following — not a computation.
His proposed physical mechanism for this sits at the speculative edge of physics, is contested, and he says so. What matters for this story is the door it opens: if minds can grasp truths no algorithm reaches, where do those truths live?
Platonic truths — the incorruptible kindWhat cannot be propagandised
Euler's identity — eiπ + 1 = 0 — cannot be reinterpreted by a demagogue or twisted to justify a war. Its meaning is contained entirely within itself: sealed against misinterpretation. Plato held that such truths — and perhaps beauty, perhaps goodness — exist independently of us: the mind does not invent them, it discovers them.
Penrose takes that view seriously all the way down into the geometry of the universe. The moral extension is a hypothesis, not a result — but the mathematical core is plain fact: some truths cannot be hijacked.
Why every -ism can be hijackedThe translation problem
Democracy, capitalism, socialism, religion, science: none is intrinsically good or bad. They are built from language, and language is porous — a regime can imprison dissidents in the name of "protecting democracy", and no fundamental constant of the universe exists to expose the misuse. When we try to carry an absolute — justice, equity, meaning — into institutions, something is lost in translation: the ideal arrives as an "-ism", a vessel that saints and tyrants can pick up alike.
No system will save us by existing. Every system needs vigilant, ethical operators — and citizens with the disposition to look for what is true. As Plato taught, all anyone can do is inculcate the disposition to discover truth.
Where ROCKR stands in this storyMove the load-bearing parts out of language
ROCKR exists to create an environment where inculcating that disposition — the disposition to discover what is true — is independently possible, for every individual and every community. We cannot make an ideology intrinsically good; nobody can. What we can do is make two moves at once: move a system's load-bearing promises out of hijackable language and into mathematics, the one medium where truth survives translation — and move the system itself out of distant institutions and into the living spaces of the local community. The four theorems are the first move made real: the guarantees people must rely on — real people, real presence, erasure without expropriation, a supply that cannot lie — stated as machine-checkable mathematics rather than terms of service (WP 8.1, Background).
And the philosophy sets the purpose as well as the method: a community that curates its own live experiences — every kind, every genre, chosen bottom up — is an environment where the disposition to discover what is true can grow. RUIPA grants make that environment open to everyone; the theorems make the liquidity behind it incorruptible.
We do not claim ROCKR is intrinsically good; nothing built by people is. We claim its guarantees are written in the one language that cannot be hijacked — and that everything else stays, as it must, in the hands of the individual and the community.
