Equity, Privacy, and Integrity with Cairo in Untrusted Environments

Epicue is a Starknet-native framework designed to provide a mathematically verifiable, Byzantine-fault-tolerant registry for societal services. It ensures that public service data is handled with absolute transparency and integrity, even in the presence of malicious nodes in untrusted internet environments.

Epicue is engineered for the untrusted Internet. Unlike typical centralized registries, Epicue incorporates Scientific BFT Resilience ($n=3f+1$):

• 2f+1 Scientific Quorum: New methodologies and research protocols require cryptographically-verified endorsements from a $2f+1$ institutional majority.
• Decentralized Governance Locks: All administrative actions (authority management, reputation floors) are strictly locked behind the EQUISYS Governor. Modifications are only executable via successful voting proposals.
• Graded Byzantine Slashing: Institutional penalties are categorized by severity (Minor, Major, Critical). Critical faults result in architectural revocation of authority.
• Security Bounties: A built-in Bounty Credit system incentivizes specialized auditors to detect and flag Byzantine faults.

The codebase is structured into logical layers to facilitate inter-institutional scale-up:

├── src/# Cairo Core Implementation
│   ├── core/           # Fundamental Logic (Access, Metadata, Types)
│   ├── triad/          # The EQUISYS Triad (Validator, Auditor, Governor)
│   ├── research/       # Scientific Productivity (BFT Peer Review, Methodology)
│   ├── social/         # Equity & Inclusion (DRI, Reputation, Bounty)

├── tests/              # Byzantine Resilience & Performance Tests
└── portal/        # Production-Grade Vite Client

The Epicue Registry Portal provides a high-fidelity interface for institutional stakeholders to interact with the Starknet-native BFT registry.

Epicue translates UN Sustainable Development Goals (SDGs) into STARK-proven metrics:

• Digital Reach Index (DRI): Measures the social equity of public services (SDG 10).
• Green Stature Index: Tracks longitudinal sustainability in manufacturing sectors like Steel Mills (SDG 12).
• FATE Compliance Score: A real-time measure of institutional accountability (SDG 16).

• Scarb (Cairo package manager)
• Starknet Foundry (snforge)

Compile the BFT-hardened contracts:

scarb build

Run the resilience suite:

snforge test

Epicue supports a unified deployment architecture for both local and public targets. See the Deployment Guide for detailed instructions.

1. Configure Environment: Choose your target.

   cp deployment/sepolia.env.template deployment/.env
   # Edit deployment/.env with your secrets

2. Run Deployment Script: Ensure your account is funded and your keystore is accessible.

   chmod +x deployment/deploy_sepolia.sh
   ./deployment/deploy_sepolia.sh

The framework enforces a rigorous $n=3f+1$ Byzantine Fault Tolerance model. Security audits are performed on-chain by the EQUISYS Triad, and proven malicious behavior results in institutional slashing.
