It depends on the platform. On Hicetnunc.xyz, buying a token on the marketplace automatically deducts 2.5% of sale to the platform (for services rendered), 10-25% to the artist (or whatever they set as royalty amount for the token), and the remainder to the seller. This is enforced via the blockchain contract, i.e. it cannot easily be circumvented on that marketplace (but it can be circumvented via peer-to-peer transfer or an alternative marketplace/contract). The wallets can all be anonymous; it just sends these tokens to different addresses.
