OpinionMarketCap: A Decentralized Marketplace for Valuable Information

Version 1.0 - April 2025

Abstract

OpinionMarketCap (OMC) introduces a novel decentralized platform that creates a marketplace for opinions and answers. By allowing users to buy the right to answer questions, it establishes a new economic model where the perceived value of information is directly reflected in its price.

This paper outlines the system's architecture, economic incentives, and security measures that combine to create a self-sustaining ecosystem for high-quality information exchange. OMC represents a paradigm shift from traditional web search and information retrieval systems toward a market-driven approach where information providers are directly compensated based on the value of their contributions.

1. Introduction

The internet has evolved into humanity's primary information repository, yet the mechanisms for determining information quality remain largely based on opaque algorithms, centralized moderation, or ad-driven business models that often prioritize engagement over accuracy. Traditional search engines like Google provide valuable services but suffer from fundamental limitations:

  • Reliance on algorithmic interpretation of content quality
  • Vulnerability to SEO manipulation and content farms
  • Misaligned incentives where advertisers, not information providers, capture value
  • Centralized control of information ranking and visibility

OpinionMarketCap addresses these limitations by creating a decentralized marketplace for opinions where:

  • Information value is directly determined by market forces
  • Content creators and answer owners are economically rewarded
  • Communities can collaboratively fund and maintain high-quality answers
  • Value flows to information providers rather than intermediaries

By leveraging blockchain technology, specifically the Base Layer 2 solution, OMC enables a transparent, efficient, and economically sustainable system for information exchange.

OMC"Best programming language 2025?""Python for versatility and AI integration"Market price: 35 USDC95% to answer owner (alex.base.eth), 3% to question creator, 2% to platform

2. System Overview

OpinionMarketCap is built as a decentralized application on the Base blockchain with a simple yet powerful economic model. At its core are three fundamental components:

2.1. Questions

Questions form the foundation of the platform. Each question:

  • Has a unique identifier
  • Has a creator who pays a fee to mint its question on OMC
  • Has a creator who receives ongoing royalties
  • Can include supplementary information via IPFS and external links
  • Is subject to character limits to ensure clarity and focus
  • Maintains a complete history of all answers and transactions

2.2. Answers

Answers represent the current response to a question:

  • The most valuable/expensive answer is prominently displayed as the current consensus, reflecting market-validated information ranking
  • Ownership of answers can be transferred through purchases
  • The price of answers increases probabilistically after each purchase
  • Answer owners capture value when their answer is purchased by others
  • Answer history records can be accessed

Example: "What's the best DEX for low slippage swaps?"

2.3. Pools

Pools enable community collaboration:

  • Multiple users can contribute funds toward changing an answer
  • Pool creators coordinate efforts to reach pricing thresholds
  • Contributors receive proportional rewards when pool-owned answers are purchased
  • Pools democratize participation when individual price points become prohibitive

3. Economic Model

The OMC economic model creates a self-sustaining ecosystem with multiple value capture mechanisms:

3.1. Dynamic Pricing

Answer prices follow a probabilistic growth trajectory:

  • Each new purchase increases the price by -15% to +99%
  • The average expected price increase is approximately 10-12%
  • Price adjustments are derived from random factors including blockchain variables
  • Price floors prevent devaluation below minimum thresholds
TransactionNew OwnerLast PriceNext PriceChangeChange %
Initialcreator.base.eth-1.00 USDC--
Purchase 1nft_bull.base.eth1.00 USDC1.18 USDC+0.18 USDC+18%

Purchase 15current_owner.base.eth18.42 USDC28.37 USDC+9.95 USDC+54%

This model creates a natural opportunity for value appreciation while maintaining market efficiency. After approximately 100 trades, the expected price can reach 2,100 USDC from an initial 1 USDC, reflecting the compound effect of multiple market participants valuing the information.

3.2. Fee Distribution

When an answer is purchased, the transaction fee is distributed as follows:

  • 95% to the current answer owner
  • 2% to the platform for maintenance and development
  • 3% to the original question creator

Previous Ownerstablecoin_expert.base.eth
Question Creatorfinance_guru.base.eth
Previous Owner Receives (95%)39.9 USDC

Platform Receives (2%)0.84 USDC

This distribution ensures that:

  • Answer owners capture significant value from their contributions
  • Question creators receive ongoing royalties for initiating valuable discussions
  • The platform remains sustainable without relying on advertising or data harvesting

3.3. Pool Economics

Pools introduce a collaborative economic model:

  • Pool creation requires a nominal fee (TBD) split between platform and question creator
  • Contributors provide funds toward a common goal
  • Rewards are distributed proportionally to contribution amounts
  • Pools enable fractional ownership of high-value answers

Example:"What's the best regulatory country for crypto companies?"
