The metaverse, with digitized identities, properties and human relations, is expected to establish a virtual society which can connect with the real world. For example, drug companies could use it to conduct clinical trials, and construction companies could explore ways to reduce waste and prevent injuries. Non-fungible tokens (NFT) applied as digital assets can memorialize one’s digital images, games, music and receipts in the metaverse. The expansion of the new digital world is giving a boost to virtual assets, despite the warnings of bubbles. New jobs like face designers for virtual games are booming. Industrial experts said the metaverse would not be possible without unified standards for blockchain technology and infrastructure. More importantly, there are ethical issues in the metaverse, involving violence, sexual harassment and privacy.
