+# 6 — Adaptive Proof of Contribution (APoC)
+
+## Overview
+Adaptive Proof of Contribution (APoC) is an AI-assisted reward allocation layer designed to complement the existing ecosystem token allocation models.
+
+Instead of distributing tokens purely based on activity quantity, APoC evaluates **quality, authenticity, economic impact, and trustworthiness** of contributions.
+
+Goal:
+Transform token distribution from "activity mining" → "value mining".
+
+---
+
+## Problem Addressed
+
+Traditional Web3 incentive models suffer from:
+
+- Bot farming
+- Sybil attacks
+- Engagement spam
+- Liquidity extraction behavior
+- Short-term participation incentives
+
+Even activity-based models can be gamed if quantity > quality.
+
+APoC introduces a dynamic scoring layer to ensure:
+> Tokens flow to contributors who create real economic value.
+
+---
+
+## Core Concept
+
+Each participant receives a dynamic **Contribution Score (CS)**:
+
+CS = Activity × Impact × Trust × NetworkEffect × Integrity
+
+Reward emission is proportional to CS instead of raw activity.
+
+---
+
+## Contribution Score Components
+
+### 1. Activity Score (A)
+Measures measurable actions:
+- Transactions
+- Purchases
+- Listings
+- Development commits
+- Service usage
+
+Normalized logarithmically to prevent spam inflation.
+
+---
+
+### 2. Impact Score (I)
+Measures economic usefulness:
+- User retention caused
+- Volume generated
+- Repeat usage
+- External adoption
+
+---
+
+### 3. Trust Score (T)
+Derived from:
+- Account age
+- KYC confidence
+- Historical behavior
+- Dispute history
+- Counterparty feedback
+
+Non-transferable and slowly changing.
+
+---
+
+### 4. Network Effect Score (N)
+Rewards users who bring valuable participants:
+- Active referrals
+- Builder ecosystems
+- Marketplace creation
+
+Not based on count — based on downstream contribution quality.
+
+---
+
+### 5. Integrity Score (G)
+AI fraud detection output:
+- Bot probability
+- Sybil clustering detection
+- Abnormal interaction patterns
+- Velocity anomalies
+
+If flagged → reward decay multiplier applies.
+
+---
+
+## Final Formula
+
+RewardShare = CS_user / Σ(CS_all_users)
+
+TokenReward = DailyEmission × RewardShare
+
+---
+
+## Emission Dampening
+To prevent reward draining:
+
+If ecosystem velocity spikes:
+EmissionRate decreases
+
+If ecosystem utility increases:
+EmissionRate increases
+
+---
+
+## Anti-Manipulation Design
+
+| Attack Type | Mitigation |
+|-----------|------|
+| Bot farms | Behavioral clustering AI |
+| Sybil accounts | Graph identity analysis |
+| Wash trading | Economic circularity detection |
+| Spam actions | Log normalization |
+| Referral abuse | Downstream contribution weighting |
+
+---
+
+## Architecture
+
+Client Activity → App Server → AI Scoring Engine → Oracle → Smart Contract
+
+AI does NOT distribute tokens.
+AI only produces a signed Contribution Score.
+
+Smart contract verifies signature and releases rewards trustlessly.
+
+---
+
+## Smart Contract Pseudocode
+
+```solidity
+struct Contribution {
+    uint256 score;
+    uint256 timestamp;
+}
+
+mapping(address => Contribution) public contributions;
+
+function submitScore(
+    address user,
+    uint256 score,
+    bytes calldata oracleSignature
+) external {
+
+    require(verifyOracle(user, score, oracleSignature), "Invalid oracle");
+
+    contributions[user] = Contribution(score, block.timestamp);
+}
+
+function claimReward() external {
+
+    uint256 reward = calculateReward(msg.sender);
+
+    require(reward > 0, "No reward");
+
+    token.mint(msg.sender, reward);
+}
