[Cryptography] [Web4] A PDE-Based, Ledgerless Digital Currency System

[Peter Fairbrother]

Sigh.

Looked at the paper, don't know why I bother.

Lots of buzz-words. Lots of wild claims. And lots of bullsh*t.


I haven't studied it in great detail, and I can't claim to be an expert 
on PDEs, but it looks like a vague outline of an undescribed-in-detail 
idea which at first glance looks exciting but which after a few seconds 
reflection won't work, at least as described, along with a lot of 
impressive=sounding but ill-founded, unfounded, and/or incorrect claims.

Spends a lot of time explaining how wonderful it is, and almost none on 
the details of how it is supposed to work.



"4:3 The system maintains a a state vector.." _ what system?

Why are you specifying the algorithms in a "cryptographic stack 
combining XChaCha20, SHA-3, HMAC-SHA3, ZKP(zero-knowledge proofs), and 
multi-variate signatures" when you don't even tell us what the 
algorithms in the stack operate on?




Nah.

:(
