I suppose blockchain can be a mechanism for the reification of pure information. So turning something that only has a value, into something that has a unique identity that can be 'pointed to'.

In the real world I might have a physical key (or some other interesting object) - there is exactly one of it and it exists in exactly one place (though of course I can create copies - but they are new objects).

In the virtual world this is a bit harder to construct and enforce - information is entirely ephemeral, and has no concrete existence or place. Maybe blockchain can provide that (in the context of the chain only of course).
