Does seem like you use Metamask (private/public key security), Discord (verification of phone#, link to meatspace) or have any NFT's (ownership/membership access/rights), otherwise you would know this is being built as we speak.
I am aware of all of those. Metamask is impressive and it should evolve to hold NFTs if it wants to survive.
in reality it's more like a multi-metaverse or a meta-multiverse.
It would be tough to translate anything between these multi-metaversii, technically speaking. I'm not sure anyone would consider it worth it.
