Interviews

Changing Blockchain Gaming

In a March 2025 interview with Be(in)Crypto, Chang discussed NEXUS and ONE Protocol (formerly CROSS), a blockchain gaming framework designed to allow individual games to issue their own tokens and represent in-game assets on-chain. He described the protocol as providing standardized smart contract templates, SDKs, and APIs intended to simplify blockchain integration for game developers, while enabling players to own, transfer, and trade game assets. The framework also included interoperability and bridging infrastructure to support asset transfers across games and blockchain networks, with QBFT consensus and dynamic gas fee delegation used for network operations. Chang also discussed the CROSS token, which was intended to support transactions, in-game purchases, asset trading, player rewards, staking, and developer monetization within the ecosystem. He identified the Opengame Foundation as a Swiss nonprofit supporting ecosystem development, research and development, developer programs, and regulatory compliance, including alignment with the EU's MiCA framework. The interview also covered efforts to attract traditional game developers to blockchain technology, planned game launches including Dragon Flight, Ragnarok: Monster World, and Rappelz M, and challenges facing blockchain gaming such as scalability, regulatory requirements, user adoption, and the need to make blockchain systems accessible to developers and players. ^[4]
