2-INTRODUCTION
1. Metaverse
“Metaverse is the universe that lies beyond the real universe, virtual with persistent
multiuser environment merging both digital and physical world.”
2. AI-Blockchain
“Blockchain as a decentralized platform with distributed ledger database can bring a
blend of centralized and distributed ecosystem. ”
3. Blockchain-Metaverse convergence
“Many blockchain-based systems now use non-fungible tokens and cryptocurrency to
create, own, and monetize decentralized digital assets. Due to the inherent flaws of
centralized data storage, blockchain exists as a decentralized, distributed database
secured by encryption, allowing users access to any digital place, particularly in a
blockchain-based metaverse. ”
