[XMR] Monero - A secure, private, untraceable cryptocurrency

[smooth]

So really not to worrisome. Quantum is the real danger.

Quantum is no danger.

Is the encryption used by VeraCrypt vulnerable to Quantum attacks?

VeraCrypt uses block ciphers (AES, Serpent, Twofish) for its encryption. Quantum attacks against these block ciphers are just a faster brute-force since the best know attack against these algorithms is exhaustive search (related keys attacks are irrelevant to our case because all keys are random and independent from each other).
Since VeraCrypt always uses 256-bit random and independent keys, we are assured of a 128-bit security
level against quantum algorithms which makes VeraCrypt encryption immune to such attacks.

I think the algorithms used in Monero are even stronger than in VeraCrypt.

Quantum attacks are potentially a danger to Monero. The distinction is that symmetric encryption like AES, etc. are much less vulnerable than signatures. All widely-used signature algorithms including those in Monero and Bitcoin are potentially vulnerable. It will be something that cryptocurrency will need to deal with in time but no one is panicking quite yet.

then its a good thing Monero has a hardfork schedule in place, I assume it could be invoked in emergencies such as an indentified quantum attack is in place and a known remedy can be implemented.

it is good to be prepared but I think it will be a while before we have to worry about that

I'd say at least another decade. But then again maybe several.

Some questions, with upfront apologies for not searching the thread for answers:

Re the current blocksize debate now creating a duststorm in the bitcoin world - is there a similar blocksize controversy in monero's future? 

Oversimplifying one aspect of the debate - centralization - if the next 3 to 5 years see a destruction of the decentralization of bitcoin, is monero in a position to observe, learn, and survive, or will monero be swept away by the same forces of centralization (in the event monero becomes the "alpha coin" after the demise of bitcoin)?

tl;dr    If centralization destroys bitcoin, will centralization inevitably destroy all cryptocurrency?

Monero has an adaptive blocksize, so no blocksize debate. The plan is to use "smart mining" and ASIC resistant POW and pruning to minimize centralization.

Cryptocurrency is not necessarily an end state, it can also be a process: I have enjoyed a great increase of freedom in my life through cryptocurrency, and I don't place a great emphasis on which particular crypto has done it in which year. In my own thinking, the "spirit of silver" moved to Bitcoin, and later to Monero, and may move on. Each move any more, is not a disruptive but incremental change - I still own more value in physical silver than Monero, for instance. All the previous stages of innovation serve as backups should the latest one end up "being forked".

The cutting edge cryptography will be tried in the high end projects first, and the trend towards fragmentation of the virtual assets sphere is also there. 2 years' slaughter has not killed any even remotely legit alts, for instance. This is an indication that in the future, you can own a myriad of virtual assets secured or unsecured by cryptography; accessed publicly, pseudo- or anonymously; and allocate your portfolio between them without friction.

also, moneromoo has come up with a pool resistance approach that passed the smooth filter, something none of my ideas have ever done. no idea how it will do in the wild.

It's more of a rough concept, no specific design, no code, etc. We'll see how it looks once some details are worked out, but there is potential it could work.

Trip report on running the windows 0.9 beta for the past week or two.  Other than the known issue of needing to type exit 2 separate times in order to exit it has been running smoothly.  It has been using <40MB memory

I've been on the latest Windows beta for ages now, have done quite a few transactions, no issues at all here.
On exit, the daemon looks to have a wait right after stopping some network function. I don't ever need to type exit 2 times. I just type exit once, then after a few seconds, I just hit enter again.

Yes that worked, Thanks

Nice report! The bolded is probably due to a slow connection or a HDD. It takes around 45-60 min to fully sync from scratch on an SSD and it took me around 4 hours on a HDD.

Did you set the bandwith limit? I think the default is 1 mbps still.

Is anyone able to reproduce this problem reliably, and able to build an arbitrary branch of monero, and willing to test and report any patch I make to try and fix this problem ?

[wpalczynski]

Anyone running any of the GUIs with the latest non official DB version of Monero?
