There's no such thing as a blockchain permanent public record. Some entity has to keep that up forever, maintained, public & accessible, for it to be such - that's not going to happen. Nearly all of them will fail and be wiped by time.

And certainly all of them can go away, they're mere digital storage systems. There's nothing permanent about any of it, not by any stretch of the imagination.

They're particularly, almost pathetically, temporary records. Most of these garbage coins will have no comprehensive financial records remaining several decades from now. By contrast, I know a lot of small businesses that have elaborate financial records going back 30-40 years, and the country is surely filled with similar (and most large corporations will have such).

Time to donate to Internet Archive asking them to preserve final block state of as many chains as possible. Shouldn’t be too expensive, my laptop is a bitcoin node and lets be do all my work, and I guess the smaller chains are smaller in disk and compute and network.
