🦀 OpenTrust Protocol (OTP) - Rust SDK

The official Rust implementation of the OpenTrust Protocol - The open standard for auditable trust in AI and blockchain systems

🚀 What is OpenTrust Protocol?

The OpenTrust Protocol (OTP) is a revolutionary framework for representing and managing uncertainty, trust, and auditability in AI systems, blockchain applications, and distributed networks. Built on neutrosophic logic, OTP provides a mathematical foundation for handling incomplete, inconsistent, and uncertain information.

🎯 Why OTP Matters

• 🔒 Trust & Security: Quantify trust levels in AI decisions and blockchain transactions
• 📊 Uncertainty Management: Handle incomplete and contradictory information gracefully
• 🔍 Full Auditability: Complete provenance chain for every decision
• 🌐 Cross-Platform: Interoperable across Python, JavaScript, Rust, and more
• ⚡ Performance: Zero-cost abstractions with memory safety guarantees

🦀 Rust SDK Features

Core Components

• Neutrosophic Judgments: Represent evidence as (T, I, F) values where T + I + F ≤ 1.0
• Fusion Operators: Combine multiple judgments with conflict-aware algorithms
• OTP Mappers: Transform raw data into neutrosophic judgments
• Provenance Chain: Complete audit trail for every transformation

🆕 OTP Mapper System (v0.2.0)

Transform any data type into neutrosophic judgments:

use opentrustprotocol::*;

// DeFi Health Factor Mapping
let health_mapper = NumericalMapper::new(NumericalParams {
    base: BaseMapperParams {
        id: "defi-health-factor".to_string(),
        version: "1.0.0".to_string(),
        mapper_type: MapperType::Numerical,
        description: Some("DeFi health factor mapper".to_string()),
        metadata: None,
    },
    falsity_point: 1.0,    // Liquidation threshold
    indeterminacy_point: 1.5, // Warning zone  
    truth_point: 2.0,      // Safe zone
    clamp_to_range: Some(true),
})?;

// Transform health factor to neutrosophic judgment
let judgment = health_mapper.apply(1.8)?;
println!("Health Factor 1.8: T={:.3}, I={:.3}, F={:.3}", 
         judgment.t, judgment.i, judgment.f);

Available Mappers

📦 Installation

Add to your Cargo.toml:

[dependencies]
opentrustprotocol = "0.2.0"

🚀 Quick Start

Basic Neutrosophic Judgment

use opentrustprotocol::*;

// Create judgments with provenance
let judgment1 = NeutrosophicJudgment::new(
    0.8, 0.2, 0.0,  // T=0.8, I=0.2, F=0.0
    vec![("sensor1".to_string(), "2023-01-01T00:00:00Z".to_string())]
)?;

let judgment2 = NeutrosophicJudgment::new(
    0.6, 0.3, 0.1,  // T=0.6, I=0.3, F=0.1
    vec![("sensor2".to_string(), "2023-01-01T00:00:00Z".to_string())]
)?;

// Fuse judgments with conflict-aware weighted average
let fused = conflict_aware_weighted_average(
    &[&judgment1, &judgment2],
    &[0.6, 0.4]  // weights
)?;

println!("Fused: {}", fused);

Real-World Example: DeFi Risk Assessment

use opentrustprotocol::*;
use std::collections::HashMap;

// 1. Health Factor Mapper
let health_mapper = NumericalMapper::new(NumericalParams {
    base: BaseMapperParams {
        id: "health-factor".to_string(),
        version: "1.0.0".to_string(),
        mapper_type: MapperType::Numerical,
        description: None,
        metadata: None,
    },
    falsity_point: 1.0,
    indeterminacy_point: 1.5,
    truth_point: 2.0,
    clamp_to_range: Some(true),
})?;

// 2. KYC Status Mapper
let mut kyc_mappings = HashMap::new();
kyc_mappings.insert("VERIFIED".to_string(), JudgmentData {
    T: 0.9, I: 0.1, F: 0.0,
});

let kyc_mapper = CategoricalMapper::new(CategoricalParams {
    base: BaseMapperParams {
        id: "kyc-status".to_string(),
        version: "1.0.0".to_string(),
        mapper_type: MapperType::Categorical,
        description: None,
        metadata: None,
    },
    mappings: kyc_mappings,
    default_judgment: None,
})?;

// 3. SSL Certificate Mapper
let ssl_mapper = BooleanMapper::new(BooleanParams {
    base: BaseMapperParams {
        id: "ssl-cert".to_string(),
        version: "1.0.0".to_string(),
        mapper_type: MapperType::Boolean,
        description: None,
        metadata: None,
    },
    true_map: JudgmentData { T: 0.9, I: 0.1, F: 0.0 },
    false_map: JudgmentData { T: 0.0, I: 0.0, F: 1.0 },
})?;

// 4. Transform data to judgments
let health_judgment = health_mapper.apply(1.8)?;
let kyc_judgment = kyc_mapper.apply("VERIFIED")?;
let ssl_judgment = ssl_mapper.apply(true)?;

// 5. Fuse for final risk assessment
let risk_assessment = conflict_aware_weighted_average(
    &[&health_judgment, &kyc_judgment, &ssl_judgment],
    &[0.5, 0.3, 0.2]  // Health factor most important
)?;

println!("DeFi Risk Assessment: T={:.3}, I={:.3}, F={:.3}", 
         risk_assessment.t, risk_assessment.i, risk_assessment.f);
