Blockchain technology can provide a solution for value transfer in the metaverse. Blockchain has evolved from a simple decentralized ledger application into a value transmission layer for virtual spaces, and it has now established a prototype for value transfer in virtual worlds. With its open-source application ecosystem and innovative business models, blockchain applications have rapidly developed and flourished, driving rapid iterations worldwide. Over the past few years, crypto assets have experienced significant price volatility, and mainstream society has held divergent attitudes toward blockchain technology and tokens. However, in terms of innovation alone, smart contracts, automated market maker (AMM) mechanisms, cross-chain solutions, and Layer 2 networks have emerged one after another. From Bitcoin to Ethereum, and then to the recent rise of DeFi and NFTs, blockchain technology has demonstrated its efficiency as a cross-spatiotemporal clearing and settlement platform.

From the perspective of the metaverse, there is an urgent need for economic rules. The reason Roblox changed "Game" to "Experience" is that in traditional centralized gaming rules, there is no transparent economic system. Pay-to-win players derive pleasure by dominating non-paying players, while they themselves are exploited by endless inflation within the game.
