Address is linked to a wallet. Wallets can sign messages to prove ownership of addresses.

  Same question for that wallet

    I'm pretty sure someone like Disney will have their wallet public on their website. They'd also likely own an ENS domain and sit all their addresses behind that, for example waltdisneyco.eth or something along those lines.

    Isn't it as easy as an official Disney representative announcing ownership of the wallet and signing a message cryptographically using their private key?
