algo - agree on the importance of general-ish purpose silicon to do the hashing, but CPU algos are still vunerable to massive parallel, (potentially) free, undetected hash. as much as 51% attacks seem to draw a collective “meh” from the crowds, I bothers me.
heavy chain - not sure about the final tx product being roughly as dense as a similar bitcoin tx. regardless, for the economic activity on the monero chain and, please correct me… an an increase of transaction frequency of average sized transactions would cause, at least, a linear increase in chain storage, correct? if so, I think my node centralization issue still applies.
inflation - its a real issue. the ability to audit the chain is pretty important to build trust. thats one of the reasons bitcoin has resisted private transactions, sending those to other layers. good, bad? who knows, but I get nervous around chains who’s very base layer is singularly opaque to an inflation bug and many others will outright reject it. not sure how devs fix this, considering monero’s (vital) core mission.
monero is a fantastic bit of dev implementation and community interaction and one of the most important chains out there, I am just suggesting that its own (unavoidable?) issues could come back and bite… hard.
