You've heard of Nostr as the ultimate public square, the place where you can finally speak freely without a company deciding who gets to speak and what can be said. It's true, but it's only half the story. The other half is less comfortable and rarely discussed: the very technology that breaks the cages of centralized social media allows for the construction of new secret rooms, with invitation lists and drawn curtains. It's not a bug or a conspiracy. It's a choice, enabled by the very structure of Nostr. This is a guide to understand the game, to see not just the open tables in the square, but also the closed doors of the private lounges that surround it.
The Megaphones of the Square: What Relays Really Are
Imagine Nostr as a giant public square. You don't shout to be heard by everyone. You use a megaphone. On Nostr, these megaphones are called relays. They are simple repeaters that take your message and broadcast it to anyone tuned into them.
Public relays are like megaphones placed in the middle of the square. Anyone can speak into them, and anyone with a receiver can listen. wss://relay.damus.io and wss://nos.lol are two of these. They are vital, open, and give the impression that everything is transparent. But they are not the only megaphones that exist.
Walkie-Talkies and Hidden Megaphones: Private Relays
Now imagine that, in that same square, there are other types of devices:
- The Walkie-Talkie with an Invite List: A relay configured with a whitelist. It accepts messages only from the public keys (
npub) the administrator has manually approved. If you're not on the list, your message is ignored. It's an exclusive club. - The Megaphone at the Secret Address: A relay hosted as an .onion service on the Tor network. Without that secret, hard-to-guess address, you can't even find it. It's a secret room whose location is known only to a few.
- The Pay-to-Play Megaphone: A relay that requires a small fee via the Lightning Network to speak or listen. An economic barrier that automatically filters the casual crowd.
The consequence is powerful: a message whispered into one of these private channels might as well never have been uttered for the rest of the square. Your app, if connected only to public megaphones, will never see it. "Privacy" here doesn't come from encrypting the message (which is also possible), but from total control over who can hear you.
The Dual-Line Phone: How the Hybrid Client Works
Here's the trick. An experienced user doesn't have to choose between the private lounge and the public square. They can have both. Their Nostr app (the client) can be configured like a phone with two distinct lines.
- Line 1 (Private): Connected to the walkie-talkie and hidden megaphone addresses of their group.
- Line 2 (Public): Connected to the big public megaphones in the center of the square.
Every time they write a post, the app asks them: "Which line do you want to send this on?".
- If they choose only Line 1 (Private), the message stays within the group. It's a confidential chat, a strategy meeting.
- If they choose both lines, the message goes to both the private group (for coordination) and the public square (for visibility).
This allows a person to live two parallel lives on Nostr: one visible to all and another reserved for a select few, using the exact same account and identity.
The Influence Game: How Perception is Manipulated
Now that we have the tools, let's see the game in action. Imagine a group of 20 technically savvy people who share a private relay (a whitelisted walkie-talkie).
- Phase 1: Coordination in the Secret Room. On their private channel, they decide: "This week we promote project X" or "We dismantle argument Y." Here they discuss freely, without worrying about public backlash.
- Phase 2: Synchronized Action in the Square. At the agreed time, all group members act. One posts an eloquent message about project X, sending it to both the private relay and the public ones (using the dual-line phone). The other 19 members, within minutes, like, repost, and comment enthusiastically on that post.
- Phase 3: The Illusion of Consensus. You, a common user connected only to public relays, what do you see? You see a post about X exploding in popularity suddenly, with dozens of positive interactions from known and respected users. Your perception is: "Wow, the community really loves this project!". You don't see the backstage coordination. You see organic, spontaneous consensus. In reality, it's orchestrated amplification.
This mechanism can build reputations, launch trends, kill discussions, or make a group opinion appear as the majority opinion. The power lies not in censoring others, but in dominating what is talked about and how it's talked about.
The Invisible Money Flow: Opaque SATS
The zap system (Bitcoin micro-payments) adds another opaque layer. Public zaps are visible and build reputation. But what happens to money within the private group?
- Value exchanges between circle members (to fund an internal project, reward each other, demonstrate trust) happen through the private relays.
- A large zap from one member to another, if sent only on the private line, is completely invisible to the public ecosystem. It creates a parallel economic circuit that fuels and strengthens the group, without anyone outside being able to measure its scale or influence.
- This private capital can be used to support the group's public campaigns, creating a hidden financial advantage.
Why Is This a Problem? The Freedom Paradox
This is not a "hack" of the system. It's the logical consequence of the freedom Nostr offers: the freedom to choose your own megaphone. The same freedom that protects the dissident allows the exclusive club to exist.
The problem is not technical, but social and one of asymmetric transparency:
- You see the public result (the popular post).
- You don't see the private process (the coordination, the internal zaps).
- This leads you to make judgments about what is genuine and important based on incomplete information.
Nostr is not corrupt. It is showing how human power dynamics really work when centralised controls are removed. Power doesn't disappear; it shifts and adapts.
How to Defend Your Perception: A Critical Lens
You can't force your way into a private relay. But you can change how you observe the square:
- Suspend disbelief about virality. When you see an opinion or project "explode" in a too-rapid and coordinated manner, pause. Ask yourself: "Could this be an orchestrated operation?".
- Look for debate, not an echo chamber. If an idea is truly solid, it will spread across different groups and circles. If it seems to exist only in a perfect bubble of consensus, that's a signal.
- Explore transparency tools. Some third-party clients or websites attempt to analyze how many relays an event comes from. An event published only on one or two major relays, with no trace on others, can be suspicious.
- Remember the golden rule of decentralization: trust is distributed, but so can manipulation be. Don't assume that the absence of a central boss means the absence of power games.
The goal is not to become cynical, but to become aware observers. Nostr is an extremely powerful tool for freedom of expression. Like all powerful tools, it can be used to build or to manipulate. Knowing its darker mechanics is not an act of distrust towards the protocol, but an act of respect for your own intelligence and for the complex truth of human sociality.
Next time you see a consensus mushrooming on Nostr, ask yourself one more question: "Is this really happening in the square, or is it being orchestrated from the secret room?". That question is the first step to seeing the network with truly open eyes.
