LoreProof

LoreProof — Proof of Ownership Layer for Steam and Gaming Assets

Bringing verified provenance to digital economies: every Steam in-game item now has provable ownership history, reputation, and real economic impact.

Short Description

LoreProof mirrors Steam items on blockchain — turning them into dynamic NFTs that record who owned them, when, and why it matters for item value, trust, and trading.

Detailed Description

🎯 Problem

In-game items today lack verifiable provenance — you can’t prove who owned a rare skin or that it belonged to a famous player.
This breaks trust in the secondary market, fuels fraud, and destroys collectible value.
Players have no proof of authenticity, and brands lose economic potential from item history.

🧠 Our Solution

LoreProof builds a Proof-of-Ownership and Provenance Layer for gaming economies.
It mirrors items (like Steam skins) on-chain as dynamic NFTs, automatically updating metadata across time-based epochs.

Each NFT records:

• Ownership lineage (player SteamIDs, timestamps)

• Player avatars and nicknames

• Optional gameplay data (kills, wins, usage — TBR)

Result: every digital asset now carries traceable, tamper-proof history, similar to certificates of authenticity in the physical world.

🏗️ Architecture

• Frontend: Next.js with Xsolla UI-kit, Wagmi
• Backend: Express.js + Viem, Steam API integration
• Smart contracts: Solidity (on Xsolla ZK Testnet)
• Storage: IPFS for metadata, with epoch-based structure
• Verification: Merkle proofs for updates
• DID Layer: Wallet ↔ SteamID binding

Example:
A player’s AWP Dragon Lore skin changes hands. LoreProof logs the event → updates metadata in IPFS → commits a new epoch to blockchain → NFT now includes verified provenance of that trade.

🎮 Use Case Demo

We showcase this with Steam-to-NFT reflection:

• Player trades a Dota2 skin on Steam.

• The new owner links their wallet via the LoreProof interface.

• The system syncs ownership, generates new metadata, and updates the on-chain epoch.

• The NFT’s metadata shows the full lineage — including Steam nicknames, avatars, and ownership periods.

🧑‍🤝‍🧑 For Whom

• Developers & publishers — who can integrate provenance into their in-game economy.
• Gamers / collectors — who value rarity, legacy, and authenticity.
• Esports fans — who want “verified legacy” items owned by pros.
• Platforms (e.g. Xsolla Backpack) — offering verified item history as a service layer.

💰 Why It Matters

Provenance creates value. Just like sports memorabilia or signed items gain +20–100% and more in price due to verified history, digital items with verifiable ownership unlock new economic potential. LoreProof transforms cosmetic collectibles into authenticated digital assets — backed by transparent, cryptographic proof.

This approach bridges Web2 gaming with Web3 transparency, giving both players and ecosystems a trust layer for digital ownership.

📈 Future Vision (Roadmap)

• Merkle proofs for instant on-chain verification of historical ownership

• zk-proof–based privacy for item provenance

• Cross-game DID identity for unified trust scores

• Integration SDK for studios & marketplaces

• “Lore Index” — global provenance analytics dashboard

🌍 Impact & Ecosystem Fit

LoreProof introduces verifiable provenance to gaming — a missing layer that transforms digital items into trusted economic assets.

• Strengthens Xsolla ZK Backpack by adding a trust layer for item history and anti-fraud verification.

• Enables cross-game reputation and item liquidity, fueling secondary markets with transparent provenance.

• Bridges Web2 → Web3: giving traditional games real, auditable ownership without compromising user experience.
