The Problem: Nostr’s decentralized simplicity creates, paradoxically, a strong pressure towards recentralization. The management complexity and operational costs of relays push users and client developers to converge on a few reliable public relays.

The Data: Field research and traffic analysis show that, despite thousands of existing relays, a handful of hubs (like relay.damus.io or relay.primal.net) handle a disproportionate share of traffic, estimated around 70%. This creates a “power-law distribution” where a few nodes become central. Academic studies confirm that decentralized protocols can re-concentrate power over key infrastructural components.

Practical Implication: The ecosystem unintentionally recreates single points of control. If one of these major hubs were to censor content or experience an outage, a huge slice of the network would be affected, undermining the promise of resilience and censorship resistance. The practical choice for a stable experience (using big relays) is in direct conflict with the decentralized ideal.
