Transparency logs like [Certificate Transparency](https://datatracker.ietf.org/doc/html/rfc6962) use permissioned chains (and other things) to distribute trust in the internet public key infrastructure.
My understanding is that CT uses Merkle trees, which can also be used in a Blockchain, but that seems to be where the association dies. Just because two things use the same underlying data type doesn't mean one is a use of the other.
My point is: when was the last time when K-means clustering or the Bayesian theorem got a cult, spawned a 10000 fake currencies and were touted as a panacea for all societal problems? The hype behind blockchain, which is just a distributed mathematically sound log of stuff, is just a bunch of misinformation shouted loudly by charlatans and uninformed enthusiasts.
It's the same thing with LLMs, they are basically an extremely sophisticated autocomplete, but I'll be damned if I don't see 1911 articles per day that claim they are sentient, and Sam the perv needs just a couple more billion dollars to reach AGI, just behind the corner. The average pundit's critical thinking is just so disappointing.
I'm not sure if you meant to reply to me? I generally agree with your points, but my specific reply was dismissing the idea that Certificate Transparency is a good use of Blockchain..
