How will we know that we are reading something authentic written by the original author vs something that has been altered and rewritten? This may have been a problem in the pre-AI world as well, but with the ease one can generate text now I wonder if there is a much greater risk.

It’s a pity that blockchain technology is so intertwined with crypto—it would make a great anti-AI check. As in, a way for a decentralized community to maintain an expanding collection of information while efficiently verifying that no existing works have been altered.

Sure, you can sign individual documents—but then for each document you need a separate channel to verify the original signature.

Friend, PGP signed messages were around in the 90s. Key signing parties. Web of trust.

Blockchain = keysigning + timestamping

Which version is earliest is relevant in this use-case.

Ohhh I get you then. Instead of checking against an author’s key, and building a distributed web of trust between trusted authors, you build a system that requires everyone collaborate on one shared chain of signatures.

Would be fun to see the "web of trust" develop into 2 non-connected subnets. Choose your own truth to live in.

Sure—the point I was trying to make is that it still needs to be done piecemeal, while a blockchain can verify a collection of works as a collection (that is, it not only verifies that each work is unaltered, it verifies it in the context of other related works).
