# Sports Integrity Bonds - VaultFire Design Specification

**Philosophy**: Real competition > rigged outcomes - Making sports meaningful again through economics.

## The Problem

Sports have lost authenticity:
- **Tanking** - Teams intentionally lose for draft picks
- **Load management abuse** - Star players sitting out competitive games for "rest"
- **Stat padding** - Players prioritizing individual stats over team success
- **Match fixing** - Gambling corruption destroying competitive integrity
- **Referee manipulation** - Inconsistent officiating, suspected bias
- **Fan disillusionment** - People stopped believing games are real

**Current incentives are broken:**
- Losing can be more profitable than winning (draft picks)
- Individual stats drive contracts more than championships
- No economic penalty for destroying competitive integrity
- Fans pay for tickets to watch teams that aren't trying

**Sports Integrity Bonds fix this by making authenticity more profitable than corruption.**

## Core Principles

1. **Competition > Manipulation** - Trying to win must be more profitable than tanking/rigging
2. **Team > Individual** - Teamwork and winning rewarded over stat padding
3. **Fans are the verifiers** - Community attestation from BOTH sides required
4. **Long-term > Short-term** - Multi-year commitment to integrity compounds
5. **No surveillance** - Public stats + fan attestation only, no privacy invasion
6. **Workers (players) protected** - Legitimate injuries won't be penalized
7. **Punish the suits** - Owners/leagues lose money when they allow corruption
8. **Transparency required** - Hidden information (injury reports, disciplinary actions) must be honest

## Bond Mechanisms

### 1. Competitive Integrity Bonds

**Who stakes**: Teams, players, leagues
**What's measured**: Effort, competitiveness, anti-tanking metrics
**Verification**: Fan attestation from both teams + public performance data
**Purpose**: Make trying to win more profitable than tanking

#### Metrics Tracked (0-100 scale):

1. **Effort Score** (public stats):
   - Hustle stats (loose balls, charges taken, defensive effort)
   - Fourth quarter performance (are they trying to close games?)
   - Back-to-back performance (do they quit on tired nights?)
   - Competitive game participation (showing up for big games)

2. **Tanking Detection** (algorithmic):
   - Win probability vs actual performance
   - Suspicious "injury" patterns (star players resting during close games)
   - Fourth quarter effort in winnable games
   - Season trajectory (giving up early vs fighting to the end)

3. **Fan Verification** (community attestation):
   - Fans from BOTH teams attest: "Was this a competitive game?"
   - NOT asking who won, asking: "Did both teams try?"
   - Requires 60%+ consensus from both fan bases
   - Geographic verification (must be from team markets to prevent brigading)

#### Economic Formula:

```
Bond Value = Stake × Effort_Score × Anti_Tank_Score × Fan_Consensus × Time_Mult

Where:
- Effort_Score = 0.0x-2.0x based on hustle/performance metrics
- Anti_Tank_Score = 0.0x-2.0x (tanking detected = 0.0x, competitive = 1.5x-2.0x)
- Fan_Consensus = 0.5x-1.5x (no verification = 0.5x, strong consensus = 1.5x)
- Time_Mult = 1.0x-3.0x (single season = 1.0x, 3+ years = 3.0x)
```

#### Penalties:

- **Obvious tanking** (score < 30): Bond depreciates to 20% of stake, 100% goes to fans who bought tickets
- **Load management abuse** (> 20 games missed for "rest"): 50% depreciation
- **No fan verification**: 50% penalty
- **Match-fixing detected**: Bond forfeited, league investigation triggered

#### Distribution:

- **Competitive season** (score 80+): 70% to players/team, 30% to fans (shared appreciation)
- **Tanking season** (score < 50): 100% to fans as compensation for watching garbage basketball
- **Mixed** (50-80): Pro-rated based on score

---

### 2. Teamwork Integrity Bonds

**Who stakes**: Players, teams, fan communities
**What's measured**: Team chemistry, assists, defensive effort, winning vs stat padding
**Verification**: Teammate attestation + fan verification + public stats
**Purpose**: Make teamwork more profitable than individual stat chasing

#### Metrics Tracked (0-100 scale):

1. **Chemistry Score** (public stats + teammate attestation):
   - Assist ratio (passing to open teammate vs hero ball)
   - Defensive effort (helping teammates, communication)
   - Bench celebrations (supporting teammates when not playing)
   - Locker room culture (teammates attest anonymously: "Does this player make us better?")

2. **Winning vs Stats** (algorithmic detection):
   - Performance in wins vs losses (stat padding in blowout losses flagged)
   - Clutch performance (do they show up when it matters?)
   - Sacrificing stats for team success (taking charges, setting screens, defensive assignments)
   - Plus/minus differential (team performs better with player on court)

3. **Teammate Verification** (anonymous surveys):
   - "Does this player make teammates better?" (0-100)
   - "Do they prioritize winning over individual stats?" (0-100)
   - "Would you want them on your team in a playoff series?" (Yes/No)
   - Aggregate only (no individual tracking)

#### Economic Formula:

```
Bond Value = Stake × Chemistry_Score × Win_Priority × Teammate_Consensus × Loyalty_Mult

Where:
- Chemistry_Score = 0.0x-2.0x based on assists, defensive effort, team metrics
- Win_Priority = 0.0x-2.0x (stat padding = 0.5x, winning focus = 1.5x-2.0x)
- Teammate_Consensus = 0.5x-1.5x (teammates verify culture contribution)
- Loyalty_Mult = 1.0x-3.0x (single season = 1.0x, 5+ years same team = 3.0x)
```

#### Stat Padding Detection:

**Red flags** (bond penalties):
- High scoring in blowout losses, disappears in close games
- Assist rate drops when team is losing (only passes when winning)
- Defensive effort only when stats are tracked
- Plus/minus consistently negative despite good individual stats

**Green flags** (bond bonuses):
- Sacrificing shots to get teammates involved
- Defensive assignments on opponent's best player
- Performance improves in high-stakes games
- Teammates attest to culture-building

#### Distribution:

- **Team-first player** (score 80+): Player gets 60%, teammates get 30%, fans get 10%
- **Stat chaser** (score < 50): 100% to teammates as compensation for dealing with them
- **Mixed** (50-80): Pro-rated split

### 3. Fan Belief Bonds

**Who stakes**: Fans
**What's measured**: Player/team integrity over time
**Verification**: Long-term performance + corruption detection
**Purpose**: Reward fans who believe in authentic players/teams, penalize corruption

#### How It Works:

1. **Fans stake on players/teams** they believe play with integrity
2. **Bonds appreciate** when player/team maintains competitive integrity over time
3. **Long-term loyalty rewarded** - Multi-year stakes earn compounding multipliers
4. **Corruption kills bonds** - If player/team caught cheating, bonds forfeit
5. **Authenticity premium** - Players who consistently show effort earn 2x-3x multipliers

#### Integrity Metrics:

1. **Competitive Effort** (from Competitive Integrity Bonds)
2. **Teamwork Culture** (from Teamwork Integrity Bonds)
3. **Scandal Detection**:
   - Gambling violations
   - PED usage
   - Match-fixing involvement
   - Referee bribery
   - Any integrity violations

4. **Consistency Over Time**:
   - Multi-year effort scores
   - No load management abuse patterns
   - Playoff performance (do they show up when it matters?)

#### Economic Formula:

```
Bond Value = Stake × Integrity_Score × Consistency × Time_Mult × Scandal_Penalty

Where:
- Integrity_Score = 0.0x-2.0x (average of competitive + teamwork scores)
- Consistency = 1.0x-2.0x (sustained effort over multiple years)
- Time_Mult = 1.0x-5.0x (1 year = 1.0x, 5+ years = 5.0x)
- Scandal_Penalty = 0.0x-1.0x (any corruption = 0.0x, clean record = 1.0x)
```

#### Corruption Penalties:

- **Match-fixing**: Bond forfeited entirely, stake goes to all other fans
- **PED usage**: 80% depreciation
- **Gambling violations**: 70% depreciation
- **Load management abuse**: 30% depreciation
- **Tanking participation**: 50% depreciation

**Clean record bonus**: +20% appreciation if player has 5+ year spotless record

#### Example Scenarios:

**Scenario 1: LeBron James (hypothetical)**
- Fan stakes $100 on LeBron in 2010
- 14 years of competitive effort, high integrity scores, no scandals
- Time multiplier: 4.5x
- Integrity score: 90/100 = 1.8x
- Consistency: 1.8x (sustained excellence)
- Bond value: $100 × 1.8 × 1.8 × 4.5 = $1,458
- **Result**: Long-term belief in authentic player rewarded

**Scenario 2: Kyrie Irving (hypothetical load management)**
- Fan stakes $100 on Kyrie in 2020
- Misses 30+ games per year for "rest", team struggles
- Effort score: 60/100 = 1.2x
- Load management penalty: 0.7x
- Time multiplier: 1.5x (4 years)
- Bond value: $100 × 1.2 × 0.7 × 1.5 = $126
- **Result**: Load management abuse limits appreciation

**Scenario 3: Player caught match-fixing**
- Fan stakes $100 in 2023
- Player caught betting on own games in 2025
- Scandal penalty: 0.0x
- Bond value: $0
- Stake redistributed to all other fans in the bond pool
- **Result**: Corruption destroys bond entirely

### 4. League Accountability Bonds

**Who stakes**: Leagues (NBA, NFL, MLB, etc.)
**What's measured**: Fan trust, officiating quality, transparency, integrity
**Verification**: Fan surveys, independent reviews, public data
**Purpose**: Make league profits dependent on maintaining integrity

#### Metrics Tracked:

1. **Fan Trust Score** (quarterly surveys, 0-100):
   - "Do you believe games are fairly officiated?"
   - "Do you believe teams are trying to win?"
   - "Do you trust injury reports are honest?"
   - "Do you believe the league prioritizes competition over money?"
   - Minimum 10,000 fan responses required

2. **Officiating Quality** (independent review):
   - Referee accuracy (last 2-minute reports, replay reviews)
   - Gambling violations (refs betting or associating with gamblers)
   - Consistency across games (are stars getting favorable calls?)
   - Fan verification from both teams: "Was officiating fair?"

3. **Transparency Score**:
   - Injury report accuracy (are teams hiding information?)
   - Disciplinary action transparency (are punishments consistent?)
   - Schedule fairness (are teams getting unfair advantages?)
   - Revenue sharing (are small markets getting screwed?)

4. **Integrity Incidents**:
   - Match-fixing scandals
   - Referee corruption
   - Tanking violations
   - PED scandals
   - Gambling violations

#### Economic Formula:

```
Bond Value = Stake × Fan_Trust × Officiating_Quality × Transparency × Integrity_Penalty

Where:
- Fan_Trust = 0.0x-2.0x (< 40 trust = 0.0x, > 80 trust = 1.5x-2.0x)
- Officiating_Quality = 0.0x-2.0x (corruption = 0.0x, clean = 1.5x)
- Transparency = 0.5x-1.5x (hidden info = 0.5x, full transparency = 1.5x)
- Integrity_Penalty = 0.0x-1.0x (major scandal = 0.0x, clean = 1.0x)
```

#### Profit Locking Triggers:

- **Fan trust < 40**: League profits locked, 100% redistributed to fans
- **Referee gambling scandal**: Profits locked until full investigation + reforms
- **Tanking epidemic** (3+ teams obviously tanking): Profits redistributed to fans who bought tickets
- **Injury report fraud**: Penalties to teams + compensation to fans

#### Distribution:

- **High integrity** (trust > 75): 50% to league, 50% to fans (shared growth)
- **Mixed integrity** (trust 50-75): 70% to fans, 30% to league
- **Low integrity** (trust < 50): 100% to fans as compensation, league earns nothing

#### Real-World Scenarios:

**Scenario 1: NBA 2023 - Tanking Crisis**
- Multiple teams shut down stars for "development" while fighting for playoff spots
- Fan trust: 45/100 (fans don't believe games are competitive)
- Officiating quality: 70/100 (refs fine, but tanking is the issue)
- Result: League bond depreciates 60%, compensation to fans who bought tickets to tanking teams

**Scenario 2: NFL - Referee Gambling Scandal**
- Referee caught betting on games they officiated
- Integrity penalty: 0.0x (zero tolerance for gambling corruption)
- All league profits locked until:
  - Full investigation completed
  - New anti-gambling protocols implemented
  - Independent oversight established
- 100% of bond value redistributed to fans

**Scenario 3: MLB - High Integrity Season**
- Fan trust: 82/100 (fans believe games are competitive)
- Officiating quality: 88/100 (umpires accurate, no scandals)
- Transparency: 90/100 (injury reports honest, disciplinary actions clear)
- Result: League bond appreciates 150%, 50% shared with fans

## Anti-Gaming Protections

### Fan Verification Safeguards:

1. **Geographic verification**: Must be from team's local market (IP + wallet location)
2. **Both sides required**: Fans from BOTH teams must agree game was competitive
3. **Sybil resistance**: One wallet = one vote, must have NFT ticket stub to vote
4. **Reputation scoring**: Fans who consistently lie get downweighted
5. **Third-party arbitration**: Disputed games reviewed by independent panel

### Stat Padding Detection:

1. **Context-aware algorithms**: High stats in blowout losses flagged
2. **Teammate verification**: Anonymous surveys from players who know the truth
3. **Historical patterns**: Consistent stat padding across seasons detected
4. **Plus/minus analysis**: Individual stats vs team performance differential

### Tanking Detection:

1. **Win probability models**: Expected wins vs actual performance
2. **Injury timing analysis**: Do stars get "hurt" right before trade deadline?
3. **Fourth quarter effort**: Teams that quit when behind flagged
4. **Historical comparison**: Current team effort vs previous years

### Corruption Prevention:

1. **Immutable records**: All attestations on-chain, can't be changed
2. **Whistleblower rewards**: Players/refs who report corruption get 10% of forfeited bonds
3. **Independent investigators**: Third-party firms verify major integrity incidents
4. **Public transparency**: All bond scores and verification data publicly viewable

## Economic Impact Modeling

### Example: NBA Full Season (2024-25)

**Assumptions:**
- 30 teams stake $10M each in Competitive Integrity Bonds
- 10,000 fans per team stake average $100 in Fan Belief Bonds
- NBA stakes $500M in League Accountability Bond

**Scenario A: High Integrity Season**
- Fan trust: 85/100
- 28 teams competitive, 2 legitimately rebuilding
- No major scandals
- Result:
  - Competitive bonds appreciate 180% = $540M total value
  - Fan Belief bonds appreciate 150% = $45M total value
  - League Accountability appreciates 140% = $700M total value
  - **Everyone wins when integrity is high**

**Scenario B: Tanking Crisis**
- Fan trust: 42/100
- 8 teams obviously tanking
- Multiple load management controversies
- Result:
  - 8 tanking teams lose 80% of stake = $64M redistributed to fans
  - League Accountability depreciates 60% = $200M to fans as compensation
  - 22 competitive teams still earn appreciation
  - **Corruption is expensive, integrity is profitable**

**Scenario C: Major Scandal**
- Referee caught match-fixing
- Fan trust drops to 30/100
- Result:
  - League Accountability bond locked entirely = $500M to fans
  - Affected teams lose 100% of stakes
  - Clean teams protected but don't appreciate
  - **Zero tolerance for corruption**

## Privacy & Surveillance Protections

### What This System DOES NOT DO:

❌ **No individual player surveillance** - Public stats only, no tracking devices
❌ **No personal data collection** - Wallets are pseudonymous
❌ **No locker room monitoring** - Teammate surveys are anonymous aggregates
❌ **No fan behavior tracking** - Only verify game attendance via NFT tickets
❌ **No biometric data** - No heart rate, location tracking, or health monitoring

### What This System DOES:

✅ **Public performance data** - Stats already available to everyone
✅ **Community attestation** - Fans verify what they witnessed at the game
✅ **Anonymous aggregate surveys** - Teammates provide culture feedback (no names)
✅ **Transparent algorithms** - All scoring formulas are public and auditable
✅ **On-chain records** - Immutable integrity history, but wallets are pseudonymous

### No Central Authority:
- Smart contracts enforce rules automatically
- Community provides verification
- Transparent algorithms (no black box)
- On-chain records can't be changed

### Privacy Preserved:
- Public stats only (already available)
- No surveillance or tracking
- Anonymous aggregate data
- Wallets are pseudonymous

### Zero Tolerance for Corruption:
- Match-fixing = bond forfeiture
- Gambling violations = immediate lockout
- Tanking = fan compensation
- Scandal = league profits locked
