# 3 Pillars of Attention

The Reward Module is our **Attention-as-a-Service** offering. It connects the Attention Layer directly to the Capital Layer. It is the engine that powers Viral City, transforming arbitrary social media engagement into measurable, on-chain value.

***

### City Passport

To ensure fair distribution and prevent Sybil attacks, City Protocol utilizes **City Passport**. This acts as an **onchain** reputation and identity layer that accurately measures a user's true contribution to the network's mindshare. 

City Passport ranks users based on their historical interactions, the quality of their User-Generated Content (UGC), and their overall engagement score within the ecosystem.

***

### AIGC Layer

To extend user capabilities in content creation, City Protocol integrates an AI-User Generated Content (AIUGC) layer. As short-form video continues to demonstrate significantly higher engagement rates relative to long-form content, and as AI-assisted generation accounts for a growing share of high-performing media, the demand for accessible, intelligent creation tooling is clear.

The AIUGC Layer empowers users to produce consistent, brand-aligned video content with viral potential, substantially lowering the barrier to entry for creators and enabling community-driven brand amplification at scale.

### Viral City

Viral City is the user-facing interface of the Reward Module. It serves as a one-stop platform for founders to measure mindshare and distribute rewards. 

Viral City features two primary components:

{% tabs %}
{% tab title="Mindshare Arena" %} <mark style="color:$primary;">**Mindshare Arena:**</mark>

An information market that tracks the mindshare of various projects (e.g., BRACKY, FARCASTER, AERODROME) via heatmaps and leaderboards.&#x20;

**Mindshare Arena** provides a smarter, fairer, and more accurate ranking system for interaction contributions.
{% endtab %}

{% tab title="Reward Hub" %} <mark style="color:$primary;">**Reward Hub:**</mark>

A UGC incentive platform where users can follow, post, and engage with campaigns to earn token bonuses.
{% endtab %}
{% endtabs %}
