Security & Verification

This document outlines the security measures, verification methods, and trust assumptions in the Hokusai ecosystem.

Security Overview​

1. Smart Contract Security​

The Hokusai protocol implements multiple layers of security:

  • Access Control: Role-based permissions for all critical functions
  • Rate Limiting: Protection against spam and abuse
  • Emergency Pause: Ability to halt operations in critical situations
  • Upgrade Mechanisms: Controlled contract upgrades with timelocks
  • Value Caps: Maximum limits on critical operations

2. Trust Assumptions​

The protocol operates under the following trust assumptions:

  • Oracle Reliability: Price feeds and performance metrics are accurate
  • Network Security: Underlying blockchain network is secure
  • Key Management: Users maintain secure control of their keys
  • Governance Integrity: Token holders act in protocol's best interest

Verification Methods​

1. Performance Verification​

Model improvements are verified through:

  • Automated Testing: Standardized test suites for each model type
  • Cross-Validation: Multiple validation methods for accuracy
  • Performance Metrics: Comprehensive evaluation criteria
  • Historical Comparison: Benchmarking against previous versions

2. Proof Systems​

The protocol uses various proof mechanisms:

  • Zero-Knowledge Proofs: For private model verification
  • Oracle Attestation: For external data validation
  • Hybrid Approaches: Combining multiple verification methods
  • Consensus Mechanisms: Multi-party verification for critical changes

Audit Procedures​

1. Smart Contract Audits​

Regular security audits are conducted:

  • Internal Reviews: Continuous code review process
  • External Audits: Third-party security assessments
  • Bug Bounties: Incentivized vulnerability reporting
  • Automated Testing: Comprehensive test coverage

2. Model Audits​

Model-specific verification procedures:

  • Performance Audits: Accuracy and efficiency verification
  • Data Quality: Training data validation
  • Bias Testing: Fairness and bias assessment
  • Resource Usage: Computational efficiency verification

Emergency Procedures​

1. Protocol Pause​

In emergency situations:

  • Immediate Pause: Critical function suspension
  • Selective Pause: Targeted operation halting
  • Graceful Shutdown: Controlled protocol pause
  • Recovery Mode: Emergency parameter updates

2. Incident Response​

Standardized response procedures:

  • Detection: Monitoring and alert systems
  • Assessment: Impact and scope evaluation
  • Containment: Limiting potential damage
  • Recovery: System restoration and verification

Security Best Practices​

1. For Users​

  • Secure key management
  • Regular security audits
  • Multi-signature wallets
  • Transaction monitoring

2. For Developers​

  • Code review requirements
  • Testing standards
  • Documentation requirements
  • Security checklists

3. For Model Providers​

  • Performance verification
  • Data quality standards
  • Resource monitoring
  • Update procedures

Verification Examples​

1. Model Improvement Verification​

def verify_improvement(
    model_id: str,
    new_performance: float,
    baseline_performance: float
) -> bool:
    improvement = new_performance - baseline_performance
    min_improvement = 0.01  # 1% minimum improvement
    
    return (
        improvement >= min_improvement and
        verify_performance_metrics(model_id) and
        verify_resource_usage(model_id)
    )

2. Oracle Attestation​

def verify_oracle_attestation(
    model_id: str,
    attestation: Attestation
) -> bool:
    return (
        verify_oracle_signature(attestation) and
        verify_attestation_freshness(attestation) and
        verify_attestation_consensus(attestation)
    )
