This is not about the immutability of the chain. You can create various collection contracts on top of the Ethereum blockchain, independent from each other. If you want to verify that I'm in fact the owner of the Nyan cat NFT you need to first decide which contract hosts the "true" Nyan cat NFT.
- iamwil 6y agoI should have made the connection more clear. Yes, you can create various collections on different chains. Say there's one on Eth, and one on Binance. If I want to purchase the NFT, which one should I buy from? Which one should I honor? Well, depends on what I value as a counter-party. I know that Binance owns all the nodes, and can roll them back at their whim. I know that no one in Eth can roll back easily. So if I value this kind of immutability as a potential owner of an NFT--I want my transactions to be final--then I'm going to go with the NFT contract on Eth. There may be other things I value instead of immutability, but the point is just the answer to "which NFT contract on which chain is the 'real one'?" is simply, "The one your counter-party honors, for whatever reason." There may be instances where both are honored at the same time, but in different domains.
- jobigoud 6y agoI understood that but you can have several instances of the same asset on a single immutable chain, for example Ethereum.
