>It's widely known there's child porn on the bitcoin blockchain,

Are there actual bytes of child porn embedded in Bitcoin blockchain or only encrypted-or-obfuscated urls of possible websites that lead to child porn?

Example story from 2018 saying child porn bytes are not in the blockchain and non-tech journalists are misreporting it: https://news.bitcoin.com/no-isnt-child-porn-bitcoin-blockcha...

Any credible embedding of child porn bytes in the blockchain since that story?

If not, an enforcement agency could always upload it itself to create the pretext. It might be expensive, but nation states can afford mining hardware.

Related question: does the cost of storing data on the blockchain on a byte basis decrease over time?

Meaning would such attacks (attaching CSAM content to a blockchain) become more feasible at lower cost in the future?

There's no fundamental link between the cost of storing data on a blockchain and time. However, practically, it does look like the most common blockchains have gotten more expensive over time: Bitcoin, Ethereum, even Dogecoin. However, you could imagine a blockchain that gets cheaper over time i.e. by issuing more coins or even stays the same.
