The data that matters is all on-chain: the smart contracts and the balances. This is why what Tim talks about has actually played out, and we have seen incredible composability between different protocols.

> We've seen this play out with OpenSea and how its view of NFTs is different from what's on chain.

If anything, the NFT ecosystem proofs this point. It consists of a dizzying array of aggregators, lending platforms, fractionalization platforms, alternative marketplaces, curation tools, API providers, all interacting with another. The fact that OpenSea retains a large marketshare among marketplaces is true (though now down to 60% - https://dune.com/sealaunch/NFT), but hasn't stopped this interoperability at all. Because in fact, what matters is on-chain, not what OpenSea exposes.
