Abstract: The Nostr protocol (Notes and Other Stuff Transmitted by Relays) represents a radically minimalist approach to decentralized social networking, built on an open network of relays and cryptographic identities. Although the protocol itself is deliberately devoid of a native token or economic consensus mechanism, the ecosystem that develops around it is deeply integrated with the Bitcoin and Lightning Network infrastructure. This integration, particularly through “Zap” micropayments, introduces powerful, verifiable economic signals. This essay argues that any reputation system built on top of Nostr is inevitably exposed to and potentially distorted by these external market dynamics. The distortion is not a flaw in the data transmission protocol but emerges in the social and economic application layers. Therefore, designing a fair reputation system must move from a naive presumption of neutrality towards an explicit recognition of these biases, incorporating active mechanisms to mitigate capture by capital, as suggested by research on decentralized reputation systems that highlights the conflict between openness and resistance to manipulation.

§1. Introduction: The Context of the Nostr Protocol

Nostr is a decentralized protocol for message transmission, designed to resist censorship and ensure account portability. Its architecture is based on two fundamental entities: clients, used by users, and relays, servers that store and forward cryptographically signed events (notes). Unlike the Fediverse (e.g., Mastodon), where user identity is tied to a specific server, in Nostr a user can publish to and be retrieved from multiple relays simultaneously, dissociating identity (a public key) from any single point of control. This model offers superior resilience and more effective decentralization, as confirmed by empirical studies showing that 93% of posts are retrievable from multiple relays. However, the economic sustainability of relays, especially free ones, remains a critical challenge. Economic analysis indicates that 95% of free relays do not cover operational costs through donations alone, pushing towards paid models and laying the groundwork for the economic distortions discussed below.

§2. Mechanisms of Market Distortion in Reputation

Although Nostr has no formal reputation at the protocol level, various informal and proposed mechanisms are susceptible to market influences.

2.1 Monetized Reputation (Zap-Driven Reputation) Zaps (Lightning micropayments) can become a paid voting system. A user with resources can “purchase” visibility and positive social signals by exchanging satoshis for perceived influence. An empirical analysis of 2.5 million Nostr events reveals substantial economic activity, demonstrating how monetary signals are already a powerful and verifiable form of social metric. The danger is that a reputation algorithm that incorporates them in a raw form legitimizes this inequality.

2.2 Paid Access and Visibility Paid relays create a direct economic filter. Users who can pay in satoshis gain access to more performant or exclusive relays, obtaining broader and more reliable distribution of their content, which is a fundamental factor for building reputation. This physically stratifies the network, creating a class of users with infrastructural advantages. Research on relay sustainability identifies this as an inevitable trade-off between ideal decentralization and practical sustainability.

2.3 The Bias of Economic “Proof-of-Work” In an ecosystem where economic commitment (in the form of donations, payments for services, or a substantial Bitcoin wallet) is easily verifiable on-chain, a cognitive bias can emerge that associates spending ability with credibility. A wealthy early adopter might be unfairly perceived as more trustworthy, a phenomenon observable also in other decentralized identity contexts, where the mere possession of digital assets is mistaken for merit.

2.4 Governance and Influence Proposals for the development of NIPs (Nostr Implementation Possibilities, the protocol standards) or community moderation could be influenced by those with greater economic weight, if such weight is implicitly or explicitly considered as a proxy for commitment or competence. This reproduces, in a decentralized form, traditional power dynamics.

§3. Consequences for a “Neutral” Reputation System and Mitigation Proposals

A reputation algorithm that completely ignores economic signals risks being irrelevant, as it overlooks a significant portion of verifiable network activity. However, incorporating them without criteria means institutionalizing and automating distortion. Research on reputation in decentralized social networks emphasizes the difficulty of creating metrics that are simultaneously open, useful, and resistant to manipulation, indicating that the social “proof-of-stake” model carries intrinsic risks.

The true design challenge, therefore, is not to create a system “pure” from market influences (impossible), but to:

1. Acknowledge and openly declare these distortion factors.
2. Actively counterbalance them in the algorithm. For example:
   • Normalize monetary data: divide the total value of Zaps received by the number of followers or by a network average, to measure average appreciation rather than the absolute wealth of supporters.
   • Give more weight to non-monetary signals: quality of social connections (Web of Trust graph), textual content, skill-based endorsements (e.g., signatures on NIPs).
   • Introduce aggressive time decay even for economic indicators, so that reputation requires continuous contribution, not a single act of spending.
   • Explicitly separate scores: distinguish “social” or content reputation from that of “economic reliability” in transactions.

§4. Conclusion

The absence of a native token in Nostr is a fundamental philosophical and technical feature, but it does not guarantee the absence of speculative or distortive market dynamics. On the contrary, integration with Bitcoin imports a system of liquid and verifiable value directly into the social fabric of the application. An honest reputation system for Nostr must therefore be designed not with a presumption of neutrality, but with an awareness of bias. It must explicitly resist the temptation to use capital as a proxy for credibility, learning from the failures of centralized reputation systems and studying alternative models based on the social graph and continuous contribution. Only an approach that openly recognizes the tension between economy and reputation can hope to mitigate it, preserving the egalitarian and open spirit that animated the creation of the protocol itself.
