As Fleta Blockchain describes in their blog – ‘Blockchain and Metaverse‘.
The Blockchain will provide the commerce infrastructure for trading within Metaverse environments.
They describe key scenarios like Gaming, where users will literally have ‘digital deed’ requirements, such as buying virtual plots of land, and of course, the currency exchange for these transactions.
So like all e-commerce it is ideally supported with a ledger system, like the Blockchain, to facilitate that type of certification and record-keeping. Fleta explores different implementations such as Ethereum, for projects like Decentraland.
