Dino Go is a Web/Mobile game where players explore real-world checkpoints, collect random letters, and mint them into Sentence NFTs.
Each NFT includes custom artwork stored on Walrus decentralized storage and is tradeable via the Sui Kiosk marketplace.

1. Explore – Players navigate a 3D map (Google Maps + Three.js).

   • Seal validates GPS within ~50m, blocking spoofing.

2. Collect – Sui's on-chain randomness fairly distributes letters (A–Z).

   • Epoch-based claim limits prevent abuse.

3. Create – In the NFT Studio, letters are atomically consumed in a Move transaction.

   • A new Sentence NFT is minted with metadata and Walrus CID.

4. Trade – The Kiosk marketplace enables:

   • Escrow-secured trades
   • Automatic royalties
   • Interoperability with other Sui markets

5. Progress – Stats, leaderboards, and seasonal events foster community growth.

Module Architecture:

• user.move
• checkpoint.move
• nft.move
• marketplace.move

Applied:

• User profiles store letter inventory as Sui Bag objects
• Checkpoint claims use sui::random for fair distribution
• NFT minting atomically consumes letters and embeds Walrus blob IDs
• Implements Kiosk-compatible listing and trading logic

Benefits:

• Object-centric design prevents double-spends
• Parallel execution supports thousands of concurrent players
• Seamless integration with external Sui NFT marketplaces

SDK Stack:

• @mysten/dapp-kit
• @mysten/sui.js
• @mysten/enoki
• @mysten/walrus
• @mysten/kiosk
• @mysten/seal

Implementation:

• Custom WalrusClient in src/web3/walrusClient.ts
• Artwork uploaded via chunked uploads, returning a blob_id

Benefits:

• 10x cheaper than on-chain storage
• Deduplication prevents storage waste
• Cryptographic proofs ensure integrity

Implementation:

• Custom SealClient in src/web3/sealClient.ts
• Location proofs encrypted before checkpoint validation
• Google Maps API keys secured with distributed threshold encryption

Benefits:

• Prevents GPS spoofing
• No single point of failure for secrets

Implementation:

• Custom KioskClient in src/web3/kioskClient.ts
• NFTs automatically compatible with external Sui marketplaces
• Move events handle fee-splitting for royalties

Benefits:

• Zero additional integration needed for cross-market trading
• Transparent royalty distribution

• Atomic Operations – Move contracts prevent partial state updates during minting
• Cryptographic Fairness – Sui randomness API eliminates distribution bias
• Decentralized Storage – Walrus reduces costs, ensures permanence
• Security – Seal encryption protects against spoofing & key compromise
• Interoperability – Kiosk standard ensures cross-ecosystem NFT trading
