comment TPM's monotonic counters
@MaartenBodewes On the contrary, this is about the implementation of a cryptography-related protocol (for storage integrity). It would be off-topic on Information Security since this isn't about the security of the protocol but about how it works.

comment Prevent double-spending with decentralized digital currencies without all transactions being public?
Mentioning Zerocash is interesting, but unfortunately your answer doesn't explain the crucial part: why is it that before spending a coin, I can prove that I own it, but after spending it that proof no longer works?

Please post text rather than an image. An image is hard to read at the wrong resolution, impossible to read if you're blind, impossible to search, impossible to copy from… You can use mathematical notations with MathJax's LaTeX-like syntax.

comment Hash functions vs Stream Ciphers in terms of Speed
I don't understand your revised question better than the original. If you want variable-sized output, what does this have to do with a hash? You seem to be asking which is faster, an apple or an orange.
