Implementation Details

Staking System

// Lock periods increase validator weight
weight_multiplier = 1.0 + (lock_days / 365.0)
validator_weight = amount * weight_multiplier

// Example: 100 tokens for 365 days
// weight = 100 * (1.0 + 1.0) = 200

Key Features:

• Configurable min/max limits prevent gaming
• Time-based locks encourage long-term commitment
• Weight multiplier rewards longer lock periods
• Relative weight for proportional consensus voting

Reward System

Pattern Validation:

reward = base_reward * stake_weight * pattern_quality

Pattern Contribution:

usage_factor = ln(usage_count + 1)
reward = pattern_bonus * quality * usage_factor

Staking Rewards:

daily_rate = (1 + APY)^(1/365) - 1
reward = stake_amount * daily_rate * days

Reward Sources:

1. PatternValidation: For validating patterns in consensus
2. ConsensusParticipation: For participating in consensus rounds
3. PatternContribution: For contributing high-quality patterns
4. Staking: For long-term token locking

Governance System

Proposal Types:

• ParameterChange: Modify system parameters
• PatternPolicy: Update pattern validation rules
• RewardAdjustment: Change reward formulas
• ProtocolUpgrade: Upgrade protocol version

Voting Mechanism:

participation = total_voted / total_stake
approval = for_weight / (for_weight + against_weight)
passed = (participation >= quorum) && (approval >= threshold)

Default Thresholds:

• Quorum: 10% (adjustable)
• Approval: 67% (adjustable)

SQL Usage Examples

Staking Operations

-- Stake 100 rUv for 90 days
SELECT qudag_stake(100.0, 90);

-- Check staking info
SELECT qudag_staking_info();

-- Claim rewards
SELECT qudag_claim_rewards();

Pattern Operations

-- Propose a pattern
SELECT qudag_propose_pattern(
  ARRAY[0.1, 0.2, 0.3]::float4[],
  '{"type": "embedding", "model": "transformer"}'::jsonb,
  50.0  -- stake amount
);

-- Check proposal status
SELECT qudag_proposal_status('prop_12345');

-- Sync patterns
SELECT qudag_sync_patterns(100000);

Governance Operations

-- Create proposal
SELECT qudag_create_proposal(
  'Increase Base Reward',
  'Proposal to increase base reward from 1.0 to 1.5',
  'reward_adjustment',
  7  -- voting days
);

-- Vote on proposal
SELECT qudag_vote('prop_12345', 'for', 150.0);

-- Check tally
SELECT qudag_proposal_tally('prop_12345', 10000.0);
