Proof of Belief (PoB)

The Cittopia Proof of Belief is a non-monetary signal of support — a public declaration that you believe cities can become measurable, comparable instruments of collective progress. It is not a token. It is not a coin. It is a name on a wall, a sentence in a manifesto, and a small, durable promise to keep watching.

What Proof of Belief Is

Most movements ask for money before they ask for trust. Cittopia inverts that order. Before we charge a single municipality for our SaaS, before we sell a single seat, we ask one question: do you believe this should exist? If yes, sign. Your signature is the proof.

PoB is borrowed in spirit from the open-source world's "stargazers" and from manifestos like the Agile Manifesto — short documents whose authority comes not from law, capital, or institution, but from the cumulative weight of named individuals who chose to put their reputation behind an idea early.

Why PoB Exists

Cittopia is a long-horizon project. We will not be a one-quarter SaaS rocket. The quality of the cities we serve, the integrity of the data we publish, the trust of the municipalities that partner with us — all of these compound over years, not sprints. PoB exists because long-horizon work requires long-horizon witnesses.

For us, the builders

Every signature is a small accountability anchor. When a citizen in Warsaw or a city CIO in İstanbul puts their name down today, they make tomorrow's compromise harder. PoB is the equivalent of writing your principles on the wall above your desk — except the wall is public, and so are the principles.

For you, the believer

Your name on the Wall of Belief is a verifiable timestamp: I saw this when it was small. It is a way to be visibly early without being asked to gamble. And — once Cittopia ships its municipal SaaS — it is a way to be invited first into pilot programs, advisory groups, and citizen-jury seats.

How It Works

1. You visit cittopia.com/proof-of-belief.
2. You enter your name, city and (optional) one-sentence "why".
3. You pick a tier — see the next section.
4. Your signature is added to the public Wall of Belief, with a tier badge and timestamp.
5. You receive a confirmation email and a permalink to your entry.

The Four Tiers

Tiers are declarative, not transactional. You pick the tier that best describes your relationship to Cittopia today. You can upgrade your tier later as your involvement deepens — but you can never be downgraded by us.

What PoB Is Not

Not a token

There is no on-chain asset. Nothing is tradeable. Nothing is speculative. There is no secondary market.

Not equity

You are not buying a share of Cittopia. You will not be diluted, vested, or paid a dividend.

Not crowdfunding

We are not raising capital from you. Cittopia's SaaS revenue model funds development; municipalities pay, citizens use it free.

Not a vote

Signing PoB does not give you governance rights. We will, however, ask the Wall for advisory input on ethics, data and city-selection decisions.

Not a contract

You owe us nothing. We owe you transparency, the quarterly letter, and the benefits of your tier — for as long as Cittopia exists.

Your Privacy

We treat your signature with the same care that the platform treats civic data. Specifically:

• Display name only. You can sign with a first name, a pseudonym, or your full name — your choice. We never publish anything you did not write into the public field.
• Email is private. Your email is only used for the quarterly letter and your permalink. We never publish it. We never share it with third parties. We never sell it.
• City is optional. You can omit it, generalise it ("a city in Europe"), or use only the country.
• Right to erasure. Email hello@cittopia.com and we remove your entry within 7 days, no questions asked.
• GDPR-compliant. Lawful basis: Article 6(1)(a) — explicit consent. Full details in the Privacy Notice.

Frequently Asked Questions

Will Cittopia ever ask me for money?

Not for the public Atlas, ever. The Atlas is and will remain free for citizens. Municipalities and institutions pay for the admin SaaS — that revenue funds the platform. Signing PoB does not create any payment obligation now or in the future.

Can I change my tier later?

Yes — upgrade only. If your role changes (you join a city, you start a civic NGO, you become a Patron) email us with your new context and we'll update your tier and badge.

Can I sign for my organization?

Yes — pick the Municipal Patron tier and write the organization name in the display name field. Patron applications are reviewed manually and published once verified.

How do I remove my signature?

Email hello@cittopia.com with the subject PoB removal. We confirm within 24 hours and remove within 7 days.

I'm a journalist. Can I cite the Wall?

Yes — the Wall of Belief is public. We ask only that you cite it as cittopia.com/proof-of-belief and link back to the page rather than republishing individual entries out of context.

How to Sign

The signing flow takes about 30 seconds:

1. Open cittopia.com/proof-of-belief.
2. Scroll to the Be a Cittopian form.
3. Pick a tier emoji. (Default is 🌱 — that's perfectly fine.)
4. Type your display name and city. Optionally write one sentence about why.
5. Click Add my name to the Wall.

Your entry appears on the Wall immediately. A confirmation lands in your inbox within a minute, with your permalink and unsubscribe link for the quarterly letter.

Acknowledgements

PoB owes its conceptual lineage to:

• Printr — for proving that "Proof of Belief" can be a document, not a token.
• The Agile Manifesto signatories — for showing that 17 names on a page can outweigh a thousand committees.
• Wikipedia's contributors — for proving that the public good is built one named edit at a time.
