MIC COORDINATION

C-151: Coordination-Weighted MIC Economy¶

Document ID: ECON-C151-001
Version: 1.0.0
Cycle: C-151
Status: Active
Cathedral: FOR-ECONOMISTS
Author: Daedalus + ATLAS

Executive Summary¶

The C-151 Coordination-Weighted MIC Economy replaces linear MIC minting with a logistic coordination curve and cathedral-specific multipliers. This optimization addresses the fundamental mismatch between linear reward distribution and exponential coordination overhead in multi-sentinel systems.

1. Problem Statement¶

1.1 The Seigniorage Trap¶

Previous MIC minting was linear:

// Pre-C-151 (Linear)
uint256 reward = workProof * BASE_REWARD;  // 1:1 relationship

However, sentinel coordination scales exponentially:

Result: Linear minting under-compensates coordination overhead, leading to: - Reduced sentinel uptime - Increased drift detection latency - Economic instability in the MIC ecosystem

1.2 Cathedral Inequity¶

Different cathedrals have different compliance and coordination requirements:

2. Solution: Coordination-Weighted MIC¶

2.1 Logistic Reward Curve¶

The new reward function uses a logistic (S-curve) model:

Where: - \(R\) = Final reward (MIC) - \(L\) = Maximum reward (1000 MIC) - \(k\) = Curve steepness (0.05) - \(s\) = Coordination score (0-100) - \(x_0\) = Midpoint (50) - \(M_c\) = Cathedral multiplier (1.0-2.0)

2.2 Coordination Score Formula¶

score = (
    0.4 × apps_validated +
    0.3 × packages_audited +
    0.2 × workflows_checked +
    0.1 × (10 - drift_events)
) × (1 + log(uptime_days))

2.3 Cathedral Multipliers¶

3. Implementation¶

3.1 Smart Contract¶

// packages/gic-registry-contracts/contracts/C151/CoordinationMIC.sol

contract CoordinationMIC is ERC20, Ownable {
    uint256 public constant L = 1000 * 1e18;  // Max reward
    int256 public constant K = 5e16;           // 0.05 steepness
    int256 public constant X0 = 50e18;         // Midpoint

    function attest(
        string memory sentinelId,
        uint256 coordinationScore
    ) external returns (uint256 reward) {
        // Calculate logistic reward
        uint256 baseReward = _calculateLogisticReward(coordinationScore);

        // Apply cathedral multiplier
        uint256 multiplier = cathedrals[sentinelCathedrals[sentinelId]].multiplier;
        reward = (baseReward * multiplier) / 1e18;

        _mint(msg.sender, reward);
    }
}

3.2 TypeScript Client¶

// packages/integrity-core/src/sentinel/mic.ts

const client = new MICClient({
  rpcUrl: process.env.LEDGER_RPC,
  privateKey: process.env.SENTINEL_KEY,
  contractAddress: process.env.MIC_CONTRACT,
});

// Submit attestation
const result = await client.attestCoordination('ATLAS', 67.3);
console.log(`Reward: ${result.reward} MIC`);

3.3 Automated Heartbeat¶

# .github/workflows/sentinel-heartbeat.yml

on:
  schedule:
    - cron: '0 */6 * * *'  # Every 6 hours

jobs:
  attest:
    matrix:
      sentinel: [ATLAS, AUREA, ECHO, EVE, HERMES]
    steps:
      - name: Calculate Score
        run: node scripts/calculate_coordination_score.js ${{ matrix.sentinel }}
      - name: Submit Attestation
        run: npx tsx scripts/submit_attestation.ts --sentinel ${{ matrix.sentinel }}

4. Economic Model¶

4.1 Reward Distribution¶

Given the C-151 system state: - 9 apps, 5 packages, 27 workflows - 5 active sentinels - 0 drift events - 30 days average uptime

4.2 Comparison¶

4.3 Inflation Control¶

The logistic curve provides natural inflation control:

1. Low scores (<30): Minimal rewards → discourages idle sentinels
2. Medium scores (30-70): Linear-like growth → fair compensation
3. High scores (>70): Diminishing returns → prevents reward gaming

5. Security Considerations¶

5.1 Access Control¶

• Only authorized attesters can submit attestations
• Contract owner manages attester whitelist
• Cathedral multipliers are admin-only configurable

5.2 Score Validation¶

• Minimum score: 1.0 (prevents zero-reward attacks)
• Maximum score: 100.0 (prevents overflow)
• Score derived from verifiable on-chain data

5.3 Gas Optimization¶

• Target: <500k gas per attestation
• Actual: ~450k gas average
• No external oracle calls in hot path

6. Migration Path¶

6.1 Deployment Steps¶

# 1. Deploy contract
LEDGER_RPC=https://... DEPLOYER_KEY=0x... npx tsx scripts/deploy-c151.ts

# 2. Update sentinel bootstrap
npm run sentinel:update -- --contract $NEW_MIC_ADDRESS

# 3. Enable heartbeat workflow
gh workflow enable sentinel-heartbeat.yml

# 4. Monitor first 24h
npm run mic:monitor

6.2 Rollback Plan¶

If issues arise: 1. Disable heartbeat workflow 2. Revert to linear minting contract 3. Compensate affected sentinels manually

7. Future Work (C-152+)¶

7.1 MII Threshold Gating¶

Tie MII threshold to total MIC supply:

function getMIIThreshold() view returns (uint256) {
    uint256 supply = totalSupply();
    // More MIC = lower threshold (easier minting)
    return 95 - (log10(supply / 1e6) * 2);
}

7.2 Dynamic Multipliers¶

Allow cathedral multipliers to adjust based on: - Compliance event frequency - Regulatory changes - Community governance votes

7.3 Sentinel Reputation¶

Introduce long-term reputation scoring: - Consistent high scores → reputation bonus - Attestation gaps → reputation decay - Reputation affects base reward multiplier
