What is Main's World?
Main's World is a social app built on a map of the real world. Every account belongs to a real, verified human being — and no account says who that human is. You post photos and videos (tapes) from the places you're actually at, you choose who can see each one, and when other people appreciate what you made, you earn something real.
That's the whole product in one breath. The rest of this page is the argument underneath it: why the internet feels the way it does, what actually changes when every account is provably a real person, and why that's hard for anyone else to copy. The Manifesto says what we believe, and What is SHIP names the category.
It's written to be read by anyone. Nothing here needs a technical background, and every term is explained where it first appears.
1. The problem
Almost everything you read online is paid for by advertising. That's not a scandal — it's just the business model, and it has a logic that follows from it with the force of arithmetic.
If a platform earns money when you see an ad, then the number of ads you see is the number that matters. That number goes up when you stay longer. So the product gets tuned, relentlessly and rationally, for time spent. Not for whether you felt better afterwards. Not for whether you saw your friends. For duration.
This is worth stating plainly, because it explains a lot that otherwise looks like incompetence:
- The feed stopped being your friends — because your friends aren't interesting enough, often enough, to hold you for an hour.
- Outrage travels further than agreement — because it holds attention, and the system cannot tell the difference between attention you wanted to give and attention it took.
- Nothing is ever finished. There's no bottom of the feed, because a bottom is a place where you leave.
None of this required anyone to be a villain. It only required a metric.
Then the bots arrived
For most of this history there was a floor under the damage: making a fake person was expensive. Someone had to sit there and type.
That floor is gone. Generated text is free and fluent. Generated faces are free and convincing. One person can now run thousands of accounts that argue, flatter, review, and befriend — well enough that you can't reliably tell.
The consequence isn't just more spam. It's that you can no longer assume the thing you're talking to is a someone. Every review might be paid. Every reply might be a machine. Every warm comment might be a funnel. And once that doubt is loose it doesn't stay confined to the fakes — it taints the real ones too. You start discounting sincerity, because you can't afford to be fooled.
That's the actual crisis. Not that the internet is full of bots, but that trust itself has stopped working, because the cheapest thing in the world to fake is being a person.
Platforms can't fix this from inside their own model. Fake accounts inflate the engagement numbers they sell. Deleting them means reporting a smaller audience to advertisers. They are structurally disinclined to solve the problem that pays them.
2. The insight
Suppose you could know — really know — that every account belonged to a distinct, living human being.
Not "verified" as in a checkmark someone bought. Not "verified" as in they handed a company their passport and hoped. Actually, provably: one person, one account.
The obvious way to get there is to make everyone identify themselves. But that cure is worse than the disease. An internet where you must show your papers to speak is not one worth having. Anonymity isn't a loophole for bad actors — it's what lets people ask embarrassing questions, leave bad situations, and be uncertain in public.
So the requirement is a paradox, and for most of the internet's life it was simply impossible: prove there's a real person here, prove there's only one of them, and reveal nothing about who they are.
How the paradox resolves
It resolves through a zero-knowledge proof — cryptography that confirms a statement is true without revealing the information the statement is about.
The everyday version: imagine proving you're over 18 without showing your birthday, your name, or your face. Not by being trusted. By producing something that can be checked, that is true, and that carries nothing else with it.
That's what World ID does for personhood. It establishes that you're a real human with exactly one account, while what you present carries no name, no email, and no way back to you. Main's World never learns who you are, because there's nothing to learn. We only ever see the proof.
So both halves hold at once. Everyone is real. Everyone is anonymous. Every other network makes you pick one.
Why this is a foundation, not a feature
Proof of personhood sounds like a spam filter. It isn't. It's what makes a different set of rules possible.
Consider what you can build once fake accounts don't exist:
- You can give people something free, every day — because "everyone" is a countable number of humans, not an unbounded number of registrations.
- Appreciation can be worth something — because it can't be manufactured. A thousand thumbs up from a thousand humans is a fact about the world.
- Actions can cost something — because there's no supply of fresh accounts to reset the cost.
- You don't need to police speech at scale — because the volume problem was always a fake-account problem.
Every one of those is impossible on an ordinary network. Not hard — impossible, because each is trivially defeated by making more accounts. Proof of human isn't a lock on the door. It's the ground the house stands on.
3. The model
Main's World is what we built on that ground: a map of the real world where every person is verified, anonymous, and somewhere.
The worlds
Every tape lives in exactly one of three worlds, and you choose which:
| World | Who can see it |
|---|---|
| SKY | Public — anyone on Main's World |
| LAND | Your connections — only Mains you've friended |
| THE DEEP | Private — yours alone, unless you tag someone in |
Privacy here isn't a settings page you're expected never to find. It's the first choice you make about anything you post. And it only ever widens by your hand: no algorithm promotes your private moment into public view, because no algorithm can. Even the one way a moment travels beyond its world — a view-only special link its creator can mint for a single tape or vibe, and kill at any time — exists only by that creator's hand.
Tapes
A tape is a post, but the word is doing work. It's a photo or video, at a real place, at a real time — you were there, then. Not content to be optimised. A memory with coordinates.
And you can travel back through the map's timeline to find them again, which is the part that surprises people: the map isn't only now. It's every then you were part of.
Vibes
A vibe is a live gathering on the map that tapes feed into. It has one rule that tells you what we're for:
No one owns a vibe. You can start one, but it doesn't come alive until someone else shows up, and it ends when everyone leaves. You cannot throw a party by yourself. The mechanic is the thesis — the thing only exists if other people choose to be there.
Crews
A crew is a named group with a shared wallet and agreed splits. When a crew makes something good together, what it earns flows to the people who made it, along rules they set themselves. Groups are how people actually do things; most networks model only individuals and their audiences.
The appreciation economy
Two balances, and they never mix.
| Where it comes from | What it's for | |
|---|---|---|
| Energy credits | 10 free every day; buy 10 more for $1 anytime | Spending inside the app. Never cashable. |
| $MAIN | Only from receiving appreciation | Yours. Spendable, or withdrawable. |
Three rules hold the whole thing up.
Appreciation is the only mint. Receiving a thumbs up is the only way $MAIN comes into existence. This is the rule everything else defends.
You can't buy your way in. Money buys credits — the ability to speak — and credits are never $MAIN. You cannot purchase the thing that measures whether people valued what you made. You can buy a ticket to play. You cannot buy the score.
You can't pay yourself. Appreciation always costs the giver and never pays the giver. There is no self-directed loop, anywhere.
Read those together and something unusual falls out: the only way to gain is to give, and the only way to be worth anything is for someone else to decide you were. Not engagement. Not reach. Not persistence. Somebody else, freely, spending something real.
Posting costs a credit, so you post less and mean it more. A tape people love pays you back; a tape nobody wanted is spent energy, gone. Nobody is punished — you just get a finite number of chances a day to be worth someone's attention, which is roughly the deal in real life.
4. Why it's durable
The obvious question: what stops a large platform from copying this next quarter?
They'd have to give up the fakes. Fake accounts inflate the numbers they sell to advertisers. Purging them means reporting a smaller audience and taking the revenue hit — something public companies are structurally very bad at doing on purpose.
They'd have to stop wanting your time. Main's World is trying to get you off the phone and into the world; success looks like a short session. That isn't a feature an ad-funded product can adopt. It's the opposite of the business.
They'd have to give up knowing you. Their model needs a profile — your name, your interests, your graph — because that's the product being sold. We can't build one. Not "we promise not to." There's nothing to build it from.
They'd have to make appreciation cost something. Free infinite likes are what make engagement look big. An economy where support costs the giver produces smaller, truer numbers. Nobody optimising a growth chart ships that.
None of these are technical moats. Any of them could be copied by a competent team in a quarter. They're structural: each one requires giving up the thing that pays for the company. That's a harder wall than any patent, and it holds precisely as long as their model does.
The one real dependency is proof of personhood — which is why Main's World is built on World. It's the network where a real human is already the unit of account. That isn't a shortcut. It's the point.
5. Roadmap
What's here now, and what's coming. We try to be honest about the difference — see the Roadmap for detail.
Live today: the three worlds on a real map, tapes with photos and video, time travel through the map's timeline, appreciation and comments, friending and following, the two-balance economy, and the first version of vibes — including vibes planned ahead, with a start, an end, and a place.
Coming: vibes you drop into like a room, with the camera as the main action and everything you shoot staying private until it ends. Crews as first-class groups with shared wallets. And SPACE — a fourth world for gatherings with no place at all, where distance becomes social rather than physical.
6. Open questions
We'd rather write these down than pretend they're settled.
What does a gathering far away look like? A vibe on the other side of the world is real, but you can't walk into it. Our current lean is that it should be unremarkable — just small, and far — but we're not certain that's right.
How should standing be shown? Ranking by lifetime appreciation received is settled, so that withdrawing your earnings costs you no standing, and standing can never be bought. What that looks like isn't.
What does a healthy paid event look like? Hosting a vibe stays free. Whether and how a host might charge to attend is still being designed, deliberately slowly — anything touching money can distort everything above it, and we'd rather be late than wrong.
How large can this get before it stops feeling like this? Every network that became unpleasant was once pleasant. We don't think we're immune. We think the rules above are our best defence, and we'd like to be argued with.
If any of this sounds like the world you want to be part of, there's a place for you here. Start with the Manifesto, or just come and see.
