>Ownership attestation is a pretty common service. Law companies do the same thing for home titles during real estate purchases, and there's definitely more than one provider of that service!
Sure, but now we're back to talking about properties of the good old common law legal system, which in some ways is already decentralized. It's not benefiting from anything provided by blockchains and crypto.
>If there were an equally trustworthy provider, or even a provider that offered better title insurance, why would people still use Opensea?
To me, it's the same reason everyone still uses Amazon. Blockchains don't change this dynamic.
>If Epic says "ownership of this digital thing gives you this other thing in game", imagine there are two ways to trade that digital thing: (1) within Epic's internal platform, or (2) on an open Blockchain.
Public blockchains do not provide any additional value here. The only important part is if there is consensus between the two parties to agree that the digital thing should mean something in both places. A public "trustless" blockchain is just noise as far as this goes. The whole thing doesn't work if there is no trust between the two parties to agree that token A should correspond to both item B and item C.
>Doesn't it stand to reason that (2) is a clearer ownership claim, with less control, and therefore more valuable? And if it's more valuable, then isn't Epic incentivized to sell their digital goods on Blockchain (and get better prices for them) than their internal platform?
I don't see how this is the case. If I'm not mistaken, you're talking about transferring an item from an Epic game to another game. That means Epic gets the initial payout for the item and the company making the other game gets nothing but still has to expend time and money supporting items that Epic got paid for. I can't see why they would agree to that.
The ownership claim also isn't clearer, both companies could still just decide to shut down their games simultaneously or retire those items and now you're left with nothing.
