Castle wars: Relay edition
Nature's many attempts to evolve a Nostr
Can relay-powered socials free us—or just crown new kings
TLDR: The piece argues centralized apps act like castles controlling your data, and Nostr’s relay model tries to break that. Commenters split: some predict new oligarchs via “paid” relays and censorship risks, others cheer the novelty—making this a big debate about who really controls social platforms.
The article paints today’s apps as feudal castles: big cloud servers own your keys, your data, and can pull the drawbridge whenever growth slows. Federation (think email or Mastodon) lets you pick your castle, but network math says the biggest fortresses still end up ruling. Enter Nostr, a relay-based social tech promising dumb pipes and user-owned keys. The crowd? Absolutely split, and absolutely spicy.
Critics went in hot. EgregiousCube predicts Nostr’s “end state” looks just like today’s oligarchs—only the lords are relays and yes, some are already “paid” toll booths. wmf drops a history bomb: peer-to-peer (computer-to-computer) chat existed in 2001, and “there’s nothing stopping” relays from censoring anyway. nunobrito says stop calling them “relays”—they’re basically “database servers.” Meanwhile gaigalas throws a nerdy rose to old-school web design, linking Fielding’s dissertation and calling this the original REST dream. The vibes get philosophical when bflesch warns Nostr ignores human needs like moderation and community norms.
Fans still gush that Nostr feels fresh and fun, but skeptics meme it as “meet the new bosses.” The joke of the day: “Not your keys, not your castle.” The roast: “2001 called—it wants its P2P back.” The drama: who gets the crown when the network grows?
Key Points
- •Modern apps use centralized client–server architectures where servers control user data and cryptographic keys.
- •RFC 9518 defines centralization and highlights the Internet’s design to avoid single controlling entities.
- •Federation enables interoperable communication across servers, exemplified by email, Mastodon, and Matrix.
- •Federation is technically straightforward, leveraging existing infrastructure; e.g., Mastodon runs on Ruby on Rails.
- •Federated networks tend toward oligopolies due to scale-free dynamics: preferential attachment, N^2 scaling, fitness, efficiency, and resilience.
