Security Stack

Multi-Layer Security Architecture

Our security architecture is built on multiple layers of protection, each designed to provide specific security guarantees while working in harmony with other layers.

Layer 1: Cryptographic Core

The foundation of our security is built on industry-standard cryptographic algorithms:

  • SHA-256 for secure hashing
  • Ed25519 for digital signatures
  • AES-256 for encryption
  • Secure RNG implementation
Cryptographic Implementation
// Hash generation for case opening
const generateCaseHash = async (
  caseId: string,
  userSeed: string,
  timestamp: number
): Promise<string> => {
  const data = new TextEncoder().encode(
    JSON.stringify({
      caseId,
      userSeed,
      timestamp
    })
  );
  
  return await crypto.subtle.digest(
    'SHA-256',
    data
  );
};

Layer 2: Smart Contracts

Solana programs that handle case operations:

  • Automated security checks
  • Regular third-party audits
  • Formal verification
  • Automated testing
Smart Contract Security
// Security checks in smart contract
#[program]
pub mod case_opening {
    use super::*;

    pub fn open_case(
        ctx: Context<OpenCase>,
        params: OpenCaseParams,
    ) -> Result<()> {
        // Verify user has sufficient balance
        require!(
            ctx.accounts.user_token.amount >= params.cost,
            ErrorCode::InsufficientBalance
        );

        // Check case is active
        require!(
            ctx.accounts.case.is_active,
            ErrorCode::CaseInactive
        );

        // Verify timestamp is within acceptable range
        require!(
            is_timestamp_valid(&params.timestamp),
            ErrorCode::InvalidTimestamp
        );

        // ... rest of the implementation
        Ok(())
    }
}

Layer 3: Oracle Network

Decentralized data feeds ensure:

  • Multiple entropy sources
  • Real-time price feeds
  • Cross-chain verification
  • Redundant providers
Oracle Integration
// Fetch data from oracle network
const getOracleData = async () => {
  const providers = [
    'chainlink',
    'pyth',
    'switchboard'
  ];

  const data = await Promise.all(
    providers.map(async (provider) => {
      const feed = await getFeed(provider);
      return {
        provider,
        value: feed.latestValue,
        timestamp: feed.timestamp,
        confidence: feed.confidence
      };
    })
  );

  return aggregateOracleData(data);
};

Layer 4: Monitoring

24/7 system monitoring includes:

  • Real-time alerts
  • Automated responses
  • Performance tracking
  • Security logging
Monitoring System
// Monitor system metrics
const monitorSystem = async () => {
  const metrics = await Promise.all([
    checkTransactionLatency(),
    monitorErrorRates(),
    trackSystemLoad(),
    analyzeUserPatterns()
  ]);

  // Alert if any metrics are outside normal range
  const alerts = metrics
    .filter(metric => metric.isAnomalous)
    .map(metric => ({
      type: metric.name,
      value: metric.value,
      threshold: metric.threshold,
      timestamp: Date.now()
    }));

  if (alerts.length > 0) {
    await notifySecurityTeam(alerts);
  }
};

Cryptographic Primitives

Core Cryptographic Implementation

Our system uses battle-tested cryptographic primitives to ensure security and fairness in all operations.

Random Number Generation

Secure RNG Implementation
// Initialize secure RNG
const secureRandom = new SecureRandom({
  entropyBits: 256,
  hashFunction: 'SHA-256'
});

// Generate random value
const randomValue = await secureRandom.generateBytes(32);

// Mix with additional entropy
const mixedEntropy = await entropyMixer.combine([
  randomValue,
  blockchainData,
  systemEntropy
]);

Digital Signatures

Ed25519 Signature Implementation
// Generate key pair
const keyPair = await Ed25519.generateKeyPair();

// Sign transaction
const signature = await Ed25519.sign(
  transactionData,
  keyPair.privateKey
);

// Verify signature
const isValid = await Ed25519.verify(
  signature,
  transactionData,
  keyPair.publicKey
);

Hash Functions

Secure Hashing Implementation
// Hash transaction data
const txHash = await SHA256.hash(
  JSON.stringify(transactionData)
);

// Create merkle tree
const merkleTree = new MerkleTree(
  transactions.map(tx => SHA256.hash(tx))
);

// Verify inclusion
const proof = merkleTree.getProof(txHash);
const isValid = merkleTree.verify(proof, txHash);

Entropy Sources

Multiple Entropy Sources

Our system combines multiple independent sources of entropy to ensure true randomness and fairness in case openings. Each source is continuously monitored and validated to maintain the highest standards of randomness.

Hardware Random Number Generator

Dedicated hardware RNG devices provide true random numbers based on physical processes:

  • Atmospheric noise sampling
  • Electronic noise measurements
  • Timing variations in hardware
  • Multiple independent devices
Hardware RNG Implementation
// Hardware RNG interface
class HardwareRNG {
  private devices: RNGDevice[];
  
  constructor() {
    this.devices = [
      new AtmosphericNoiseRNG(),
      new ElectronicNoiseRNG(),
      new TimingRNG()
    ];
  }

  async getEntropy(): Promise<Buffer> {
    // Collect entropy from all devices
    const samples = await Promise.all(
      this.devices.map(device => 
        device.collectSamples(32)
      )
    );

    // Mix samples using XOR
    return samples.reduce(
      (acc, sample) => acc.map(
        (byte, i) => byte ^ sample[i]
      )
    );
  }

  validateEntropy(sample: Buffer): boolean {
    return this.runStatisticalTests(sample);
  }
}

Blockchain Data

Blockchain-derived entropy includes:

  • Recent block hashes
  • Transaction data
  • Network statistics
  • Cross-chain data points
Blockchain Entropy Collection
// Collect blockchain entropy
async function getBlockchainEntropy(): Promise<Buffer> {
  // Get recent block data
  const recentBlocks = await connection
    .getRecentBlockhash();
  
  // Get recent transactions
  const transactions = await connection
    .getConfirmedSignaturesForAddress2(
      programId,
      { limit: 10 }
    );

  // Combine data sources
  const data = Buffer.concat([
    Buffer.from(recentBlocks.blockhash),
    Buffer.from(JSON.stringify(transactions)),
    Buffer.from(Date.now().toString())
  ]);

  // Hash combined data
  return crypto.createHash('sha256')
    .update(data)
    .digest();
}

System Events

System-level entropy sources include:

  • High-precision timing data
  • Network packet timing
  • System interrupts
  • User interaction patterns
System Event Collection
// System entropy collector
class SystemEntropyCollector {
  private buffer: Buffer;
  private events: SystemEvent[];

  constructor() {
    this.buffer = Buffer.alloc(32);
    this.events = [];
  }

  // Collect system timing data
  addTimingData() {
    const hrtime = process.hrtime();
    this.events.push({
      type: 'timing',
      value: hrtime[1], // Nanoseconds
      timestamp: Date.now()
    });
  }

  // Add network event
  addNetworkEvent(packet: NetworkPacket) {
    this.events.push({
      type: 'network',
      value: packet.timestamp,
      metadata: packet.headers
    });
  }

  // Generate entropy from collected events
  async generateEntropy(): Promise<Buffer> {
    const eventData = this.events.map(event => 
      JSON.stringify(event)
    ).join('');

    return crypto.createHash('sha256')
      .update(eventData)
      .digest();
  }
}

Entropy Validation

Entropy Validation Process
// Validate entropy quality
async function validateEntropy(
  entropy: Buffer
): Promise<ValidationResult> {
  // Run NIST statistical tests
  const nistResults = await runNISTTests(entropy);

  // Check entropy bit strength
  const bitStrength = calculateBitStrength(entropy);

  // Verify minimum entropy requirements
  const meetsRequirements = 
    bitStrength >= MIN_ENTROPY_BITS &&
    nistResults.every(test => test.passed);

  // Check for patterns
  const patterns = detectPatterns(entropy);

  return {
    isValid: meetsRequirements && !patterns,
    bitStrength,
    testResults: nistResults,
    patterns
  };
}

Computation Protocol

Secure Computation Process

Our computation protocol ensures fair and verifiable case opening results through a multi-step process. Each step is designed to be transparent and verifiable while maintaining the integrity of the random outcome.

Case Opening Protocol

The case opening protocol follows these steps:

  • Collect entropy from multiple sources
  • Generate and verify random number
  • Map random number to item outcome
  • Record result on blockchain
  • Transfer item to user
Case Opening Protocol
// Case opening implementation
class CaseOpeningProtocol {
  constructor(
    private case: Case,
    private user: User,
    private entropyCollector: EntropyCollector
  ) {}

  async openCase(): Promise<OpeningResult> {
    // Collect entropy
    const entropy = await this.collectEntropy();

    // Generate random number
    const randomNumber = await this.generateRandom(
      entropy
    );

    // Map to outcome
    const outcome = await this.mapToOutcome(
      randomNumber
    );

    // Record result
    await this.recordResult(outcome);

    // Transfer item
    await this.transferItem(outcome.itemId);

    return outcome;
  }

  private async collectEntropy(): Promise<Buffer> {
    return this.entropyCollector.collect([
      'hardware',
      'blockchain',
      'system'
    ]);
  }

  private async mapToOutcome(
    randomNumber: number
  ): Promise<Outcome> {
    const items = await this.case.getItems();
    return this.case.determineOutcome(
      items,
      randomNumber
    );
  }
}

Outcome Mapping

Random numbers are mapped to outcomes using a deterministic process:

Outcome Mapping Implementation
// Map random number to item
class OutcomeMapper {
  constructor(
    private items: CaseItem[],
    private totalProbability: number = 100_000
  ) {}

  mapToOutcome(
    randomNumber: number
  ): CaseItem {
    let currentProb = 0;
    
    // Sort items by rarity (ascending)
    const sortedItems = [...this.items]
      .sort((a, b) => a.probability - b.probability);

    // Find matching item
    for (const item of sortedItems) {
      currentProb += item.probability;
      if (randomNumber <= currentProb) {
        return item;
      }
    }

    // Fallback to most common item
    return sortedItems[sortedItems.length - 1];
  }

  validateProbabilities(): boolean {
    const sum = this.items.reduce(
      (acc, item) => acc + item.probability,
      0
    );
    return sum === this.totalProbability;
  }
}

Result Verification

Each case opening result can be independently verified:

Result Verification
// Verify case opening result
class ResultVerifier {
  constructor(
    private case: Case,
    private blockchain: BlockchainConnection
  ) {}

  async verifyResult(
    openingId: string
  ): Promise<VerificationResult> {
    // Fetch opening data
    const opening = await this.blockchain
      .getTransaction(openingId);

    // Verify signatures
    const validSignatures = await this.verifySignatures(
      opening
    );

    // Verify entropy sources
    const validEntropy = await this.verifyEntropy(
      opening.entropy
    );

    // Verify outcome mapping
    const validOutcome = await this.verifyOutcome(
      opening.randomNumber,
      opening.outcome
    );

    return {
      isValid: validSignatures && 
               validEntropy && 
               validOutcome,
      details: {
        signatures: validSignatures,
        entropy: validEntropy,
        outcome: validOutcome
      }
    };
  }
}

Probability Model

Statistical Fairness Model

Our probability model ensures fair and transparent case openings through rigorous statistical analysis and continuous monitoring of outcome distributions.

Probability Distribution

Each case has a defined probability distribution:

Probability Distribution
// Define case probabilities
interface ItemProbability {
  itemId: string;
  rarity: string;
  probability: number;  // Out of 100,000
}

const CASE_PROBABILITIES: ItemProbability[] = [
  {
    itemId: "rare_item_1",
    rarity: "Covert",
    probability: 250  // 0.25%
  },
  {
    itemId: "rare_item_2",
    rarity: "Classified",
    probability: 1_250  // 1.25%
  },
  {
    itemId: "uncommon_1",
    rarity: "Restricted",
    probability: 6_250  // 6.25%
  },
  {
    itemId: "common_1",
    rarity: "Mil-Spec",
    probability: 31_250  // 31.25%
  },
  {
    itemId: "common_2",
    rarity: "Industrial",
    probability: 61_000  // 61%
  }
];

// Validate probabilities
function validateProbabilities(
  probabilities: ItemProbability[]
): boolean {
  const total = probabilities.reduce(
    (sum, item) => sum + item.probability,
    0
  );
  return total === 100_000;
}

Statistical Analysis

Continuous statistical analysis ensures fairness:

Statistical Analysis
// Analyze case opening statistics
class StatisticalAnalyzer {
  constructor(
    private timeWindow: number = 24 * 60 * 60 * 1000  // 24 hours
  ) {}

  async analyzeDistribution(
    caseId: string
  ): Promise<AnalysisResult> {
    // Get recent openings
    const openings = await this.getRecentOpenings(
      caseId,
      this.timeWindow
    );

    // Calculate observed frequencies
    const observed = this.calculateFrequencies(
      openings
    );

    // Get expected probabilities
    const expected = await this.getExpectedProbabilities(
      caseId
    );

    // Perform chi-square test
    const chiSquare = this.performChiSquareTest(
      observed,
      expected
    );

    // Check for anomalies
    const anomalies = this.detectAnomalies(
      observed,
      expected
    );

    return {
      chiSquare,
      pValue: this.calculatePValue(chiSquare),
      anomalies,
      isValid: this.isDistributionValid(chiSquare)
    };
  }

  private calculateFrequencies(
    openings: CaseOpening[]
  ): Map<string, number> {
    const frequencies = new Map<string, number>();
    
    for (const opening of openings) {
      const current = frequencies.get(opening.itemId) || 0;
      frequencies.set(opening.itemId, current + 1);
    }
    
    return frequencies;
  }
}

Fairness Verification

Multiple methods ensure fairness:

  • Chi-square goodness of fit tests
  • Kolmogorov-Smirnov tests
  • Run sequence analysis
  • Autocorrelation checks
Fairness Tests
// Implement fairness tests
class FairnessVerifier {
  async verifyFairness(
    openings: CaseOpening[]
  ): Promise<FairnessResult> {
    // Run chi-square test
    const chiSquare = await this.chiSquareTest(
      openings
    );

    // Run KS test
    const ksTest = await this.kolmogorovSmirnovTest(
      openings
    );

    // Check for runs
    const runTest = await this.runTest(
      openings
    );

    // Check autocorrelation
    const autocorr = await this.autocorrelation(
      openings
    );

    return {
      isValid: this.allTestsPassed([
        chiSquare,
        ksTest,
        runTest,
        autocorr
      ]),
      confidence: this.calculateConfidence([
        chiSquare,
        ksTest,
        runTest,
        autocorr
      ]),
      details: {
        chiSquare,
        ksTest,
        runTest,
        autocorr
      }
    };
  }
}
