# Infomarket

### **The Problem**

Attention is the most supply-constrained resource in crypto, yet no protocol-level infrastructure exists to systematically generate, quantify, or settle it. 

This gap is particularly acute for maturing ecosystems like Base, where core DeFi primitives and liquidity infrastructure are already well established. 

Viral City is building a coordination layer that connects projects with creators, converts engagement into measurable signal, and transforms attention into compounding growth. 

> Without this layer, capital-rich ecosystems are left competing for mindshare using ad-hoc, unverifiable, and non-composable tooling that fails to scale.

### **The Vision**

<figure><img src="/files/XUhQsRrdAWZGBW7P0WZA" alt=""><figcaption></figcaption></figure>

Virality Leaderboard is the attention layer for Base.

It is the platform where projects distribute rewards to creators based on quantifiable contributions — and where creators are ranked, recognized, and compensated for the mindshare they generate. It creates a powerful feedback loop: projects fund attention, creators produce it, and users discover through it.

Integrated into the Viral City Base mini-app, Virality Leaderboard is designed to be the **first step any project takes to onboard to Base.**

It is composed of two core modules: **Infomarket** (measuring mindshare) and **City Rewards** (distributing rewards).

### Architecture Overview

Infomarket is the mindshare indexing and measurement engine within the Virality Leaderboard, serving as the attention layer for Base. It provides real-time, continuously computed rankings of both project-level and creator-level mindshare across the Base ecosystem, derived from content activity and engagement signals on the Base App.&#x20;

The system surfaces three indexed views:&#x20;

1. **Market Map** (project mindshare distribution),&#x20;
2. **Top Gainers / Losers** (project momentum delta),&#x20;
3. **Creator Leaderboard** (individual creator influence ranking).&#x20;

All three are driven by a unified, multi-factor scoring schema.

Infomarket is paired with **City Rewards**, the programmable settlement layer responsible for distributing value against scored contributions. Together, they form the complete Virality Leaderboard: Infomarket scores attention, and City Rewards settles it. Integrated natively into the Viral City Base mini-app, the Virality Leaderboard is designed to function as the default onboarding surface for any project seeking distribution on Base.

### Mindshare Scoring Schema

All Infomarket rankings are derived from a unified set of weighted factors computed per scoring epoch.

**Project Mindshare Factors**

<table><thead><tr><th width="175.015625">Factor</th><th>Definition</th></tr></thead><tbody><tr><td><strong>Creator Volume</strong></td><td>Count of unique, quality-filtered creators producing content attributed to the project within the epoch. Sybil-resistant: only accounts passing minimum credibility thresholds are counted.</td></tr><tr><td><strong>Cast Volume</strong></td><td>Total number of project-attributed casts published on the Base App, deduplicated and spam-filtered.</td></tr><tr><td><strong>Engagement Depth</strong></td><td>Aggregate weighted engagement (reactions, replies, recasts, quote-casts) across all project-attributed content, normalized by engagement source credibility.</td></tr></tbody></table>

**Creator Mindshare Factors**

<table><thead><tr><th width="174.11328125">Factor</th><th>Definition</th></tr></thead><tbody><tr><td><strong>Content Quality</strong></td><td>Volume of casts published on the Base App that exceed a minimum quality threshold, assessed via NLP-based originality scoring, informational density, and relevance classification.</td></tr><tr><td><strong>Engagement Yield</strong></td><td>Total weighted engagement received across all casts, adjusted for organic signal versus bot-amplified noise.</td></tr><tr><td><strong>Network Strength</strong></td><td>Count of smart followers (quality-weighted, active accounts) on the Base App, serving as a proxy for distribution reach and audience credibility.</td></tr></tbody></table>

### Market Map & Top Gainers/Losers

#### Market Map

Market Map renders each project's proportional share of total ecosystem mindshare on the Base App as a normalized percentage. A higher allocation indicates greater attention dominance relative to all indexed projects within the current epoch.

Strategies that empirically increase Market Map share include shipping products with demonstrable product-market fit within the Base ecosystem, maintaining consistent engagement cadence with Base-native users, and distributing rewards equitably to high-performing creators. This last point is reflexive by design: fair reward distribution itself generates secondary content and engagement, creating a compounding attention loop.

**How to increase Market Map %:**

1. Launch innovative products or initiatives with clear PMF within Base.
2. Consistently engage Base users.
3. Distribute rewards fairly to top creators.

#### Top Gainers/Losers

Top Gainers / Losers is a momentum-indexed view that surfaces projects exhibiting the sharpest positive or negative mindshare delta between consecutive scoring epochs.&#x20;

It identifies which projects are rapidly accruing narrative dominance and which are experiencing attention decay, enabling both creators and capital allocators to orient toward emerging momentum in real time.

#### **Creator Leaderboard**

<figure><img src="/files/RHrR9qnXZvSit3LEAPbJ" alt=""><figcaption></figcaption></figure>

#### Creator Leaderboard

Creator Leaderboard ranks individual creators by cumulative mindshare contribution across the entire Base ecosystem, not scoped to a single project but aggregated across all content and all campaigns. Top-ranked creators are those who have consistently produced high-quality, high-engagement content and have established broad audience credibility on the Base App.

**How to increase Creator ranking:**

1. Create insightful content about projects in the Base ecosystem.
2. Consistently contribute to projects featured on Virality Leaderboard.
3. Produce engaging content that earns sustained, authentic engagement.
