Here are some current use cases of blockchain technology in gaming, along with examples that can be researched online:

In-Game Asset Ownership and Trading
Blockchain allows players to truly own, buy, sell, and trade in-game assets such as skins, weapons, and characters. These assets are often represented as non-fungible tokens (NFTs).

Example: CryptoKitties - a blockchain-based virtual game where players can buy, sell, and breed unique digital cats.

Play-to-Earn (P2E) Games
Blockchain-powered games enable players to earn cryptocurrency or NFTs through gameplay, which can be traded or sold for real-world value.

Example: Axie Infinity - a popular blockchain game where players breed, raise, and battle fantasy creatures called Axies.

Decentralized Gaming Platforms
Platforms built on blockchain facilitate decentralized game development, distribution, and governance.

Example: Enjin Platform - provides blockchain tools for game developers to create, manage, and trade virtual goods.

Esports and Tournament Transparency
Blockchain ensures transparency and fairness in esports tournaments, including prize distribution and match results.

Example: Chiliz / Socios - uses blockchain to engage esports fans and manage voting and rewards.

NFT-based Gaming Collectibles
Collectible cards and items that are tradable NFTs, creating new monetization avenues for game publishers.

Example: Gods Unchained - a blockchain-based trading card game where cards are NFTs.

Tokenized Gaming Economies
Use of native tokens within games to incentivize players and create in-game economies.

Example: Decentraland - a blockchain-based virtual world with its own economy and land ownership as NFTs.
