> **๐ฆ The official Rust implementation of the OpenTrust Protocol - The MATHEMATICAL EMBODIMENT OF TRUST ITSELF**
## ๐ฅ **REVOLUTIONARY UPDATE: v3.0.0 - Performance Oracle & Circle of Trust**
**OTP v3.0.0 introduces:**
- **Zero Pillar**: Proof-of-Conformance Seals (cryptographic proof of specification compliance)
- **First Pillar**: Performance Oracle (Circle of Trust for real-world outcome tracking)
Every fusion operation now generates a **cryptographic fingerprint** (SHA-256 hash) that proves the operation was performed according to the exact OTP specification. Additionally, the Performance Oracle system enables tracking real-world outcomes to measure the effectiveness of OTP-based decisions.
This transforms OTP from a trust protocol into **the mathematical embodiment of trust itself**.
### **๐ก๏ธ What are Conformance Seals?**
- **๐ Cryptographic Proof**: SHA-256 hash of the fusion operation
- **โ
Mathematical Verification**: Anyone can verify conformance independently
- **๐จ Tamper Detection**: Any modification breaks the seal instantly
- **โก Self-Auditing**: OTP audits itself through mathematics
### **๐ฏ The Revolution**
This solves the fundamental paradox: **"Who audits the auditor?"**
With Conformance Seals, OTP audits itself through mathematics. No more blind trust in implementations - every operation is mathematically provable.
### **๐ฎ What is the Performance Oracle?**
The Performance Oracle is the **First Pillar** of OTP, enabling the **Circle of Trust**:
- **๐ Judgment IDs**: Unique SHA-256 identifiers for every decision
- **๐ Outcome Tracking**: Link decisions with real-world results
- **๐ Performance Measurement**: Measure calibration and effectiveness
- **๐ Learning Loop**: Continuous improvement through feedback
- **๐ฏ Trust Validation**: Prove that OTP decisions lead to better outcomes
### **๐ The Circle of Trust**
1. **Decision**: OTP makes a decision with a unique Judgment ID
2. **Action**: The decision is acted upon in the real world
3. **Outcome**: The Performance Oracle records the actual result
4. **Learning**: The system learns from the decision-outcome pair
5. **Improvement**: Future decisions become more accurate and trustworthy
## ๐ **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.
### **๐ฏ Why OTP Matters**
- **๐ Trust & Security**: Quantify trust levels in AI decisions and blockchain transactions
- **๐ Uncertainty Management**: Handle incomplete and contradictory information gracefully
- **๐ Full Auditability**: Complete provenance chain for every decision
- **๐ Cross-Platform**: Interoperable across Python, JavaScript, Rust, and more
- **โก Performance**: Zero-cost abstractions with memory safety guarantees
## ๐ฆ **Rust SDK Features**
### **Core Components**
- **Neutrosophic Judgments**: Represent evidence as (T, I, F) values where T + I + F โค 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
## ๐ **Quick Start with Conformance Seals**
```rust
use opentrustprotocol::{NeutrosophicJudgment, conflict_aware_weighted_average, verify_conformance_seal_with_inputs};
fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create judgments
let judgment1 = NeutrosophicJudgment::new(
0.8, 0.2, 0.0,
vec![("sensor1".to_string(), "2023-01-01T00:00:00Z".to_string())]
)?;
let judgment2 = NeutrosophicJudgment::new(
0.6, 0.3, 0.1,
vec![("sensor2".to_string(), "2023-01-01T00:00:00Z".to_string())]
)?;
// Fuse judgments (now with automatic Conformance Seal generation)
let fused = conflict_aware_weighted_average(
&[&judgment1, &judgment2],
&[0.6, 0.4]
)?;
// Verify mathematical proof of conformance
let is_mathematically_proven = verify_conformance_seal_with_inputs(
&fused,
&[&judgment1, &judgment2],
&[0.6, 0.4]
)?;
if is_mathematically_proven {
println!("โ
MATHEMATICAL PROOF: This judgment is 100% conformant!");
} else {
println!("โ WARNING: Conformance verification failed!");
}
// Extract the Conformance Seal
let seal = fused.provenance_chain.last().unwrap().conformance_seal.as_ref().unwrap();
println!("๐ Conformance Seal: {}", seal);
Ok(())
}
```
### **๐ OTP Mapper System (v0.2.0)**
Transform any data type into neutrosophic judgments:
```rust
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**
| **NumericalMapper** | Continuous data interpolation | DeFi health factors, IoT sensors |
| **CategoricalMapper** | Discrete category mapping | KYC status, product categories |
| **BooleanMapper** | Boolean value transformation | SSL certificates, feature flags |
## ๐ฆ **Installation**
Add to your `Cargo.toml`:
```toml
[dependencies]
opentrustprotocol = "0.2.0"
```
## ๐ **Quick Start**
### **Basic Neutrosophic Judgment**
```rust
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);
```

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

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