Value Separation

The Value Separation Mechanism represents the cornerstone innovation of the Creek protocol, decomposing gold's intrinsic value into distinct stable and volatile components. This sophisticated algorithmic framework enables the creation of differentiated financial instruments, each with precisely calibrated risk exposure characteristics. Through a synergistic interplay of advanced computational modules, the mechanism delivers unprecedented granularity in value quantification and allocation.

Gold Stability Valuation Mechanism (GSVM)

Advanced Algorithmic Architecture

The GSVM functions as the protocol's sophisticated pricing oracle for determining the stable value component (sValue) of Gold tokens:

  • Adaptive Time-Weighted Valuation Algorithm:

    sValue(t) = α × EMA120(t) + (1-α) × [β × EMA90(t) + (1-β) × SpotPrice(t)]

    Where:

    • EMA120 denotes the 120-day exponential moving average

    • EMA90 represents the 90-day exponential moving average

    • SpotPrice reflects the current oracle-supplied market price

    • α and β are governance-adjustable parameters (default configuration: α=0.8, β=0.7)

  • EMA Calculation Methodology:

    EMA(t) = Price(t) × (2 ÷ (period + 1)) + EMA(t-1) × (1 - (2 ÷ (period + 1)))

    This exponential weighting methodology ensures that recent price data receives appropriate significance while maintaining sufficient historical context.

Volatility Quantification and Parameter Calibration

Volatility Measurement Protocol

  • Statistical Methodology: Implements 30-day rolling standard deviation (σ) as the primary volatility metric

  • Calculation Framework:

    σ = √[(Σ(P(i) - P̄)²) / n]

    Where P(i) represents individual daily price observations and P̄ signifies the arithmetic mean price over the measurement period

Market Condition Classification Framework

  • Standard Volatility Regime: σ within ±15% deviation from its 180-day moving average

  • Elevated Volatility Regime: σ exceeding its 180-day moving average by >15%

  • Subdued Volatility Regime: σ below its 180-day moving average by >15%

  • Extreme Volatility Regime: σ exceeding its 180-day moving average by >40%

Parameter Auto-Calibration System

Foundational Parameter Configuration:

  • Standard market conditions: α = 0.80 (baseline)

  • Complementary β parameter: 0.70 (baseline)

Dynamic Adjustment Algorithm:

α_new = α_base + k × ln(σ_current / σ_baseline)

Where:

  • α_base constitutes the baseline α value (0.80)

  • k represents the adjustment sensitivity coefficient (recommended range: 0.15-0.25)

  • σ_current denotes the currently observed volatility metric

  • σ_baseline signifies the 180-day historical average volatility

Parametric Constraints:

  • Lower bound: α ≥ 0.65 (applicable during subdued volatility regimes)

  • Upper bound: α ≤ 0.95 (applicable during extreme volatility regimes)

  • Maximum instantaneous adjustment magnitude: Δα ≤ ±0.05

Transition Management Protocol:

  • Progressive adjustment implementation: maximum daily parameter shift limited to Δα ≤ 0.015

  • Temporal stabilization: 7-day cooldown period between significant recalibrations

Execution Optimization Architecture

  • Anomalous Data Identification: Implements statistical detection algorithms to isolate and exclude potential outlier price inputs that could compromise valuation integrity

  • Scheduled Recalculation Cycles: Executes computational updates within predetermined, gas-efficient temporal windows

  • Computational Efficiency: Employs advanced data compression techniques and batched processing methodologies to minimize on-chain resource utilization

sValue

Value Decomposition Algorithm

The Value Decomposition Algorithm constitutes the mathematical core of the Creek protocol's innovation, systematically bifurcating gold's aggregate market value:

  • Fundamental Bifurcation Equation: Implements the primary calculation vector:

    vValue = gPrice - sValue

    Where:

    • gPrice represents the current market price of gold

    • sValue denotes the stable value component derived through the GSVM

    • vValue constitutes the resultant volatile value component

  • Boundary Condition Management: Incorporates specialized algorithmic logic for handling market conditions where gPrice descends below sValue, maintaining consistent positive vValue representation through implementation of floor thresholds and proportional reallocation methodologies

  • Accounting Integrity Framework: Maintains precise ledger consistency, ensuring that:

    gPrice = sValue + vValue

    This invariant guarantees conservation of value across the system at all times

Leverage Coefficient Quantification System

The Leverage Coefficient Quantification System continuously calculates and updates the intrinsic leverage characteristics embedded within GY tokens:

  • Real-time Leverage Calculation Engine:

    LR = gPrice / vValue

    Where LR represents the effective leverage ratio of GY tokens relative to the underlying gold asset

  • Parametric Constraint Enforcement: Implements protocol-defined minimum and maximum leverage boundaries to prevent excessive risk concentration while maintaining appropriate capital efficiency

  • Market Transparency Protocol: Provides continuous on-chain visibility into current leverage metrics, facilitating informed trading decisions and risk management strategies

  • Dynamic Responsiveness: The system automatically modulates GY token capital efficiency as a function of market conditions:

    • Leverage increases as gold price approaches the EMA-derived stable value

    • Leverage decreases as the differential between market price and stable value expands

Oracle Integration Architecture

The Oracle Integration Architecture secures the provision of reliable, manipulation-resistant price data essential for all protocol valuation operations:

  • Diversified Data Acquisition: Integrates gold price feeds from multiple independent providers, establishing redundancy and minimizing single-point failure risk

  • Statistical Validation Framework: Implements advanced mathematical methodologies to identify and exclude anomalous price inputs:

    • Interquartile range analysis

    • Z-score deviation metrics

    • Temporal consistency evaluation

  • Temporal Weighting Protocol: Applies sophisticated exponential time-weighting algorithms to recent price data, providing:

    • Enhanced manipulation resistance

    • Appropriate sensitivity to genuinely significant market movements

    • Reduced vulnerability to short-term artificial price distortions

  • Systemic Recalculation Triggering: Oracle updates automatically initiate comprehensive recalculation of all dependent protocol variables, including sValue, vValue, and leverage coefficients

System Advantages & Technical Differentiation

  • Enhanced Stability Architecture: The implementation of advanced multi-timeframe exponential moving averages provides superior price smoothing characteristics while maintaining appropriate responsiveness to legitimate market trends

  • Adaptive Intelligence: Sophisticated algorithmic frameworks automatically recalibrate key operational parameters in response to evolving market conditions

  • Manipulation Resistance: Comprehensive multi-layered security mechanisms effectively mitigate the impact of attempted price manipulation strategies

  • Computational Efficiency: Optimized on-chain execution frameworks minimize transaction costs while maintaining robust calculation integrity

  • Governance Extensibility: Key system parameters remain accessible to protocol governance, enabling community-directed optimization while preserving core architectural integrity
