I think the difference here is that the URL in dat is not a guarantee of immutability - it is just a public key and the author of the dat is free to update the content at any time without changing the key (there is a change history though).
I am not an expert on this - just a casual passing interest so might have it wrong.

- StavrosK 7y agoOh hmm, thanks. I've seen that link, but I'm not interested in getting into the byte-level, I just want a high-level overview. A URL being a public key that you can update if you have the private key makes sense, thank you. Do you know how propagation/distribution happens? With IPFS, whoever accesses your content serves it for some time.
- mattlondon 7y agoI believe the distribution is largely the same concept, i.e. you get a copy of the data from somewhere, then other nodes that are also looking for the same data might discover that you have it as well and so you might then serve it on to those other nodes too.
