And also these random operations must not go into an infinite loop and/or crash in any way

<n​eromonero1024:monero.social> the only concept here I'm having difficulty understanding is the preservation of entropy on the hash state

<n​eromonero1024:monero.social> would you please explain it in simplified manner? all the search results are about cryptography and full of complex mathematics

RandomX avoids operations that reduce entropy (total amount of information in the scratchpad). For example, logical AND will have a result data with more and more zeroes in it, which will reduce entropy

<n​eromonero1024:monero.social> ah... understood
