Vertcoin - First Scrypt N | First Stealth Address - Privacy without mixer

[BorisTheSpider]

We have been discussing this issue for weeks, we're well aware of it, if it was desirable to fix it (or if a convenient opportunity to do so arose) we'd fix it.

Boris.. what's your opinion on this fix though.. is it legit in your opinion?

Hi Micryon, thanks for your contributions to the discussions about the exploit - I've seen you around in the threads. At first glance the proposed fix looks OK to me, but we haven't really tried to wring it out and come up with exploit scenarios against it - I'd encourage anyone considering implementing a fix to:

a. Weigh up the pros and cons carefully

b. Always bear in mind that untested code is risky, it's not always easy to perceive where you may be opening a new exploit while fixing a known one etc.

c. Consider other options as well, like less frequent retargets

One of the reasons we forked to KGW early on, rather than trying to reinvent the wheel, was because it's production tested. Now we have a situation where an exploit does seem to exist (but hasn't been demonstrated) yet the hashrate of VTC means we have no real need to address it urgently (although that's not to say we haven't considered the options, we are in fact testing some stuff now) - for chains with a much smaller hashrate (who are at much greater risk of a 51% attack) it seems a somewhat serious issue, but the proposed fix may not necessarily be the best in the sense that even if it's good, it is untested and carries risks.

Ive tried again to compile the source on RHEL 6.5, but no luck. Im not familiar with this stuff, if anyone can offer advice, I could really use some help here.
Is there any chance of someone having a prebuilt binary? Im really lost on how to do this compile.

# ./autogen.sh
./autogen.sh: line 8: aclocal: command not found

# yum search aclocal

Autogen? What source are you trying to build? Whatever it is you need to install automake and autoconf

This may be a dumb question, but are you sure you're trying to compile VTC!!!!! We don't use autogen?

make -f makefile.linux in /src ought to do it.

I found the source here. Is this the wrong source for cpu miner?

https://github.com/Bufius/cpuminer-vert

Tried to cd into src, but doesn't exist...
-ksh: cd: src: [No such file or directory]

Ah I see - I thought you were building the coin daemon or qt wallet. You probably want the automake package.

Indeed, aclocal is part of automake. A good place to start would probably be: yum groupinstall "Development Tools"

Im trying to see if I can get hold of a RHEL/CentOS pre-combinled X64 binary.
Failing that, I tried to grab the software and compile it myself, but I don't have any experience with compiling things, so when it errors, im pretty much out of my comfort zone.
Is there a different source I should be using?

Ill give that a try. Thanks

hi guys,

i wish i had switched to mining vert back when i first saw this thread. i knew it had potential i just didn't want to modify my mining rigs. anyhow, the coin i'm mining now, fluttercoin, the block reward is gonna start decreasing rapidly and i want to switch to vertcoin. can someone point me to a thread on how to mine vert using a vert bamt? i know it's out there, but i can't find it, and it's not in the OP. thanks.

I'm not up to date with what guides there are atm, but you can try looking at http://www.reddit.com/r/VertcoinMining/comments/1xt73i/vertcoin_mining_guide/ or in general in that subreddit.

Hi Micryon, thanks for your contributions to the discussions about the exploit - I've seen you around in the threads. At first glance the proposed fix looks OK to me, but we haven't really tried to wring it out and come up with exploit scenarios against it - I'd encourage anyone considering implementing a fix to:

a. Weigh up the pros and cons carefully

b. Always bear in mind that untested code is risky, it's not always easy to perceive where you may be opening a new exploit while fixing a known one etc.

c. Consider other options as well, like less frequent retargets

One of the reasons we forked to KGW early on, rather than trying to reinvent the wheel, was because it's production tested. Now we have a situation where an exploit does seem to exist (but hasn't been demonstrated) yet the hashrate of VTC means we have no real need to address it urgently (although that's not to say we haven't considered the options, we are in fact testing some stuff now) - for chains with a much smaller hashrate (who are at much greater risk of a 51% attack) it seems a somewhat serious issue, but the proposed fix may not necessarily be the best in the sense that even if it's good, it is untested and carries risks.

Thanks man.. all good points.

I've been testing the fix on my testnet it seems o.k. but you are right it does carry risk , esp in this part of the code.. and hard forking itself is a lot of risk.  I totally agree with VTC not taking it. .. but was just curious what your thought was.. given i need to decide to make this decision for GPUC.

I have a question for all of you, not necessarily specific to vertcoin per se but digital currency as a whole with input from those of you who are coders for crypto currencies.

To keep it simple this whole digital currency craze has peaked my interest in so many ways over this past year that it makes me want to go back to school. I've realized after much thought that I carry 2 separate interest in the digital currency space and i don't want to double major though. The two separate areas are the economics of how digital currencies are affecting people worldwide and also the technological aspect as in wanting to fully understand the blockchain technology and what mining really is on a programming level.

I guess my question to you guys in the first place is what sort of program or programs would i even have to take to for example be on Boris' level of understanding the software mechanisms behind digital currencies? I currently have a minor degree in computer networking but that has nothing to do with programming, the only reason I even learned about bitcoin is because I have been working at this company called XFX for a few years, they are a manufacturer of AMD graphics cards and I do tech support for people who purchase our products (this is how i first found out about people mining since they would call me after they broke their cards doing it.)  I see you guys talking about coding and such with vertcoin and I am so lost and I think to myself jeez I almost want to go to school just so I can fully understand this stuff....

And then on the other hand I think to myself if i'm just interested in the economics of it, how in western cultures we are like "oh cool, something new and sparkly but meh the volatility is stupid" but in third world countries they could really change their entire lifestyles for the better with the introduction of digital currencies and I am super interested in putting myself in a position to understanding and dealing with such things but ofcourse to go that route I'd have to go get a economics degree.

You see the separation here? Do I go to school to be a programmer just to fully understand block chain from a technical aspect or do I go for the economics degree? This is why I wanted to hear just what kind of school programs have you programmers gone through or better yet, how many years of study and experiences did it take for you guys to be able to be on the level you guys are on? Designing crypto graphic currencies is so far beyond my understanding I almost want to shoot myself sometimes lol.

Is there anybody who is working on 1click mining in extendend version of wallet ? I think it can have presetes and you have to choose your gpu, or there can be gpu autodetection.

will there be a video from CCCNYC ?
