Understanding NFTs and Blockchain in Video Games

What are NFTs?

NFT Video Games: Sony Files Patent for NFT and Blockchain Technology in Gaming

Non-fungible tokens (NFTs) are digital assets that represent unique items or content, making them ideal for use in video games. Unlike cryptocurrencies like Bitcoin, which are fungible and can be exchanged for one another, NFTs cannot be exchanged on a one-to-one basis. Each NFT has its own distinct value and characteristics, perfect for representing digital collectibles, artwork, and in-game items.

The Role of Blockchain in NFTs

Blockchain technology plays a crucial role in the creation and management of NFTs in video games. It ensures that the ownership and provenance of digital assets are secure and transparent. When you buy an NFT, you receive a digital certificate that proves your ownership of that specific asset, allowing creators and collectors to buy, sell, and trade digital goods while maintaining a verifiable record of the asset’s history.

Sony’s Patent: “Tracking Unique In-Game Digital Assets Using Tokens on a Distributed Ledger”

Key Features of the Patent

Sony has filed a patent titled “Tracking Unique In-Game Digital Assets Using Tokens on a Distributed Ledger,” which suggests the company’s plans to incorporate NFT and blockchain technology into video games. The patent includes detailed diagrams outlining the process of tracking changes in ownership, visual appearance, or metadata of digital assets, such as in-game items, characters, and digital media of gameplay moments like video clips or images.

Potential Applications

The patent filed by Sony hints at various potential applications for NFTs and blockchain in gaming. These applications could include tracking and verifying the ownership of unique in-game assets, creating new revenue streams for game developers through the monetization of digital assets, and enabling cross-platform and cross-game compatibility for digital items.

Successful NFT Video Games

In the videogame industry we already have cases of successful games that leverage the power of NFTs:


CryptoKitties is a blockchain-based virtual game that allows players to adopt, raise, and trade virtual cats. Each CryptoKitty is an NFT with unique attributes, and players can breed their cats to create offspring with new combinations of traits. CryptoKitties was one of the first successful NFT video games and helped to popularize the concept of NFT gaming.

Axie Infinity

Axie Infinity is a popular NFT-based video game where players collect, breed, and battle fantasy creatures called Axies. Each Axie is an NFT with its own unique traits, and players can earn in-game tokens through battles and trading Axies with others. The game has gained significant attention in recent years, demonstrating the potential of NFT video games to create engaging and profitable ecosystems for players and developers alike.

The Sandbox

The Sandbox is a virtual world and gaming platform where players can create, buy, sell, and trade digital assets in the form of NFTs. Users can design and build their own virtual environments, assets, and games, which can then be monetized through the platform’s native cryptocurrency, SAND. The Sandbox highlights the potential for NFT video games to foster creativity and enable user-generated content.

Implications for the Gaming Industry

Digital Ownership and Monetization

Sony’s patent could pave the way for true digital ownership of in-game assets in NFT video games, allowing players to buy, sell, and trade items with other players. This would open up new monetization opportunities for game developers, who could tokenize in-game items as NFTs and create marketplaces for these assets.

Cross-Platform and Cross-Game Compatibility

The patent also suggests that Sony’s technology could enable cross-platform and cross-game compatibility for digital assets in NFT video games. This would allow players to use their digital items across different games and platforms, significantly increasing the value and utility of these assets.

Challenges and Limitations

Technical and Legal Considerations

Despite the potential benefits of Sony’s patent, there are still technical and legal challenges to overcome in implementing NFT and blockchain technology in video games. These challenges include ensuring the security and scalability of blockchain networks, addressing potential copyright and intellectual property issues, and navigating the regulatory landscape surrounding digital assets.

Cooperation Among Developers and Platforms

Successful implementation of NFT and blockchain technology in video games will require cooperation among developers and platforms to adopt standardized approaches and systems. This collaboration is crucial in order to provide seamless experiences for players and ensure the growth and sustainability of NFT video game ecosystems.

The Future of NFT Video Games

Opportunities for Developers and Players

As NFT video games continue to gain popularity, there will be ample opportunities for developers and players to benefit from this emerging market. Developers can create innovative gaming experiences that leverage digital ownership and monetization, while players can enjoy new levels of engagement, customization, and value through their in-game assets.

Balancing Innovation and Potential Drawbacks

The future of NFT video games will require balancing innovation with potential drawbacks, such as concerns over environmental impact, market volatility, and potential exclusion of players who cannot afford to participate in NFT-driven economies. Addressing these challenges will be crucial in ensuring the long-term success and adoption of NFT video games.


Sony’s patent for NFT and blockchain technology in gaming represents a significant step forward for the industry. As NFT video games continue to evolve and grow, we can expect to see further innovations in digital ownership, monetization, and cross-platform compatibility, creating exciting new opportunities for developers and players alike.
