Epic Games' CEO Tim Sweeney recently shared his thoughts on the potential for integrating blockchain technology into Fortnite. He responded to a question from Jonah Blake, co-founder of Game Fund Partners, saying that blockchain might be used in the future, but not in the way many people might expect.

What Started the Conversation

The discussion began with a tweet from Jonah Blake, co-founder of Game Fund Partners. Blake speculated that there was a 50 per cent chance we might see blockchain technology or cryptocurrency in Fortnite within the next five years. He also suggested that Unreal Engine could incorporate blockchain in the future. Blake's exact tweet read, “There is a 50 per cent chance in the next 5 years we see an Unreal Engine blockchain. We may see crypto in Fortnite very soon.”

In response, Sweeney tweeted, “Perhaps someday,” indicating that while he is open to exploring blockchain, it would not involve cryptocurrencies or NFTs. Sweeney clarified that his interest lies in blockchain’s capabilities rather than its financial applications. He emphasized, “As we’ve plainly said many times we aren’t adopting cryptocurrency or NFT trading or similar.” 

Technical Interest in Blockchain

Sweeney has shown a keen interest in the technical aspects of blockchain rather than its financial applications. He described blockchain technology as "awesome," focusing on its potential as a decentralized database. Furthermore, Sweeney envisions using blockchain to manage and update game data in a decentralized manner, similar to how traditional games use multiple databases. He believes that this approach could significantly enhance how game data is handled, making it more efficient and reliable.

Tim Sweeney further expanded on his thoughts about blockchain technology by describing it as a tool for managing mutable states, which involves using transactions to ensure the state evolves consistently. He tweeted, “A blockchain is a mechanism for negotiation of mutable state which uses transactions to ensure the state evolves with the strong consistency property from concurrency theory. Other solutions include database transactions, software transactional memory, and sequential execution.” This explanation highlights Sweeney’s understanding of blockchain as a method to maintain data integrity and consistency, which is critical for complex systems like games.

The Open Metaverse Idea

Sweeney is also a strong advocate for the concept of an "open metaverse," where different virtual worlds and games can interact and collaborate. In response to a tweet from Jonah Blake, Sweeney explained that in such a metaverse, each participant would control what is allowed in their own space. He stated, “In an open metaverse where many creators (companies or individuals) participate together in an evolving simulation, it would be up to each participant to decide what comes in and out of the spaces that are notionally ‘theirs’.”

He believes that no single company should control the entire metaverse and that open standards and protocols are essential for this vision. However, he cautions against unrealistic expectations, such as easily transferring assets from one game to another. Instead, he supports practical solutions that allow for meaningful interaction between games while respecting each game's unique rules and systems.

Challenges and Optimism

Epic Games' CEO acknowledges that blockchain technology has faced significant challenges, including speculation, scams, and regulatory issues. Additionally, he regrets that the technology’s association with financial markets has negatively impacted its reputation. Despite these issues, he remains optimistic about blockchain’s potential and believes it will eventually prove its value. 

As Epic Games looks into blockchain's potential, Sweeney's focus is on how the technology can improve game development and data management, rather than its financial uses.
