⭐ StellarVeriphy — The Truth Engine for the Stellar Ecosystem

StellarVeriphy is a decentralized digital content verification and provenance platform built on the Stellar blockchain. It enables creators, developers, and platforms to generate immutable authenticity proofs for digital media directly on-chain using Soroban smart contracts — Stellar's native smart contract platform built on Rust/WASM.

By leveraging Stellar's ultra-low transaction fees (~0.00001 XLM), fast 3–5 second finality, and energy-efficient Stellar Consensus Protocol (SCP), StellarVeriphy makes large-scale content verification affordable, scalable, and environmentally sustainable.

🌐 What StellarVeriphy Solves

Digital media today can easily be manipulated, forged, or misrepresented — deepfakes, AI-generated content, tampered documents. StellarVeriphy provides a robust solution through:

• Tamper-proof content provenance — records the history and origin of content immutably on Stellar.
• Cryptographic authenticity verification — uses advanced cryptographic techniques to verify media has not been altered.
• On-chain certification — mints a permanent record on Stellar that acts as a "digital birth certificate" for the asset.
• Trustless third-party verification — external apps can verify media without relying on a central authority.
• Secure encryption and access control — protects sensitive media while allowing controlled sharing.
• Developer APIs — simplifies integration of trust verification into existing workflows.

⚙️ Key Features

📂 Media Provenance Verification

• Upload images, videos, documents, or AI-generated media.
• Attach a JSON manifest describing origin metadata (creator, timestamp, device info).
• Generate immutable authenticity certificates on Stellar.

🔐 Encryption & Access Control (KMS)

• Encrypts media before it enters the storage layer.
• Controls decryption permissions — creators specify who can view content.
• Supports key rotation and audit trails for enterprise-grade security.

🧠 Trusted Off-Chain Verification (TEE Oracle)

• AWS Nitro Enclaves provide a highly isolated compute environment.
• Oracle Worker Nodes orchestrate data flow between storage and the TEE.
• Cryptographic Attestation — the TEE generates a signed proof that verification ran correctly.

📜 On-Chain Provenance Certificates (Soroban)

Each minted certificate contains:

• Storage reference ID (IPFS CID or DB ID)
• Manifest hash
• Attestation proof hash
• Timestamp and creator identity (Stellar public key)

🧪 Proof-as-a-Service APIs

• POST /api/verify/submit — submit media for verification
• GET /api/verify/status/:jobId — check verification status
• POST /api/webhook — receive real-time callbacks
