Understood.

Apologies to any mods reading this. It was not my intention to "giveaway" coins but rather to demo the zk anon. the amounts sent represented very small nominal sums and were sent purely in the interests of education.

I will move this action to www.shadowtalk.org and post a link here later.

if you feel it necessary to delete these posts I understand.

Thank you.

Soepkip, days have past. Could you please share your thoughts on our PR plans. We really need your help to get the ball rolling. I can't believe im trying convince our community manager to actually reply. Theres loads of people that are willing to donate for these projects! Help us, so we can help you...

Hello all,

Thanks for helping to spread the word about SDC but please note that giveaways are against BCT's ToS. Please move the giveway over to www.shadowtalk.org so our thread doesn't get closed!

Thanks all!

Thank you!  My wallet is still syncing up

not sure if i agree. sdc seems good to me

Dear skip60,

I don't get you; what's your problem? You're one of the loudest here, almost non-stop complaining about price dropping.. Do you honestly think, that you (3!) guys are the only ones buying SDC?

Based on how you behave, you might have a lil' too much in SDC, when you're freaking out every time the price drops. Either believe in Shadow and deal with it or sell it and find something else – there are plenty of guys who'll gladly buy your stash.

• do you believe in SDC? Great. Keep it, be happy you can buy more really cheap AND take part in community efforts, spread the word about SDC, write an article.. I don't care. If you don't like the price, DO something about it and don't just throw nonsense accusations around..
• don't you believe in SDC? Too bad for you. Sell what you have (or at least those excessive amounts you act like you have) and enjoy the peace of mind.

In the end, it's pretty easy.
Cheers.

Nice one with the job board. The whole election/treasurer thing will be unnecessary. Im sure that a Team member will address the matter of a PR donations addy now the some members of the community are calling for it. Having said that there is one which exists in shadowhangout as pointed out earlier in the thread. If that is handled by a team member then we just need a confirm it is still "working".

sell your sdc and go away

Who the fuck is selling non-stop???

i afraid we will be the bag holders, me, dadon, fearcoka haha

Ask and you shall receive… http://shadow.blockexplorer.cc/tx/b21d4928fce302d218c0f042f0dfdd8e6f0558d85ff8c75d5d97af38e8127d20 …welcome to Shadow!

AFter hitting "suggest ring size" it sent with a ring size of 27!!!

who's next? (just a couple more to complete this demo…)

I'll take some, please....

Thanks!

As long as we a) all start converting some amounts of SDC to Shadow and b) use primarily Shadow>Shadow as a preferred means of transaction then ALL these concerns have been addressed.

The most STUPID thing a user could do with this system is to receive an SDC>Shadow tx and immediately convert ALL of it back via Shadow>SDC. Even though there is still plausible deniability even in this event it is just plain silly to do so. Perhpas some safeguards could be built in to prevent this stupidity. just like a pop-up saying "this action will weaken the anon, select a different amount"…

Once we all have 25-60% of our SDC in Shadow and principally use shadowsend (shadow>shadow) then the anon is complete. When people convert amounts of Shadow back to SDC, they are redeemed into a brand new SDC addy generated by your wallet on-the-fly.

Vis-a-vis SDC pos staking being compromised by Shadow token creation I doubt this'll be an issue. If this network is used to its ful potential that 2% interest could turn out to be a valable incentive to stake. Notwithstanding established exchanges will deal in SDC for the foreseeable future. IN fact for them its great. They dont get any heat for dealing with an anon coin (from Governments) since it is not in its anon state when they deal it.

I really look forward to seeing the available SDC supply decrease as we turn Shadow… Investors will go "hmmm"  

you make some good points, but for a 3rd party to be gathering evidence like that the person they are surveling is probably very naughty and therefor very careful, yes the person they are transacting with could e careless resulting in them being exposed we need to address this good point, but for normal everyday people who like privacy or are committing minor felony's( buying some weed or avoiding tax etc) it's not really a problem imo.

Then there is probably no usable link. But it all depends on timing, the amounts involved, the volume of transactions, etc.

As you say a wallet can help, and having a very successful coin with a lot of activity can help (in fact this is necessary; you simply can't hide by yourself, even with zerocash this is true).

True


Well that depends. Circumstantial evidence can and is used in court, as part of a case. One little clue like this probably doesn't prove a case by itself but it could still be a relevant piece of evidence. It can be used as surveilance to start or continue an investigation to gather more direct and more damning evidence. In countries that don't quite abide by the rule of law it might make you look guilty enough to for bad things to happen even without "proof." I'm pretty sure that isn't what you want either.

Also, who's talking about court necessarily though? I thought the idea was actually keep one's transactions private, for example from competitors, employees, employers, former business partners, customers, suppliers, political opponents, repressive regimes looking to track and/or cut off funding to dissidents, ex-spouses, stalkers, etc., not just (perhaps narrowly) evade prosecution. I have no idea though, perhaps that is not the goal of SDC. It is certainly the goal of other coins I won't mention here.


Not entirely. If I send coins to you, I have no control of how careless you might be with the coins I just sent you. If you transact with them in a careless manner, that creates clues that may point back to me. It also contradicts the notion of "ease of use" if the onus is on the user to "be careful" all the time, or leave a trail.

More to the point, consider the case of blockchain analysis. The goal of which is to take little pieces of information and put them together to make inferences about what types of transactions are for what purpose. That's how bitcoin tracing actually works in practice. There is no direct label on most addresses/transactions that tell exactly what they are, but by treating the blockchain as big data you can process it and make inferences.

The goal of anonymous technologies like shadow (at least as far as I know) is to remove those clues and stop the surveilance. It's more effective if you aren't incorporating transparent addresses and traceable transactions at a high frequency.

But as I said if it isn't used too much and most transactions are Shadow->Shadow, then this is nothing to worry about. So I guess its just a question of seeing how it plays out in practice.

I suspect coreteam has/is still trying to connect with family after months of coding.  However I do would like a active presence here.  Though I understand that IRC is the prefered place for questions/support etc.  And there is the http://shadowtalk.org/ forum that we have been encouraged to use as well.    BTCtalk has really fallen to the wayside for many coins focus, for good reason I am sure.    However I do use BTCtalk as my primary source for crypto informations.  Perhaps this is a mistake!

Do we really have a community manager?

I havent seen him for a very long time, he is not active lately

Do we pay him, maybe it is the problem

Dadon and i asked couple of questions about bounty and pr, will anyone from coreteam will ever answer

Dadon, fearcoka and me.... Are we the only ones who keep on buying sdc

Who the hell sells that much sdc, what is the reason for selling and why he continues to sell

And many more questions i have

That's just guessing it's not proof it's circumstantial could not e used as evidence would not stand up in a court of law, and is fixed by not being careless and almost impossible to do once the network grows, anybody who is careless enough to expose themselves like that and as i said before will be almost impossible to do when the network grows big does not care about privacy or have anything to hide, this tech is for people who do care and will be careful, but anyways won't matter soon the network will be far to big to guess, it could be done but won't be because the 3rd parties who snoop on people like that know that the intelligence they are gathering is a waste of time and resources because it's circumstantial, so it really isn't a big deal, and once the network grows you would almost have to try too expose yourself for a 3rd party to guess in example sending a very unique amount of coins, but even then the 3rd party would be guessing and it would be circumstantial so once again they can't use the intelligence gathered for anything useful so they will not bother.

What if you send me 27 coins, then I send myself 3 more Shadow, then I convert 21 coins back to SDC tomorrow and 9 more next Tuesday?

I think that what's more important is that the user is in control of how often that happens. Some will screw it up for sure. Future versions of the wallet can help with that.

This.


No it does not make sense at all. I send you 27 coins and soon thereafter you "mint" 27 new coins. It becomes pretty clear where my 27 coins went.

This won't always happen of course. What I said above is that if it happens a lot, then anonymity is compromised. If it happens rarely or not at all, then it isn't an issue.


Here I agree. There are advantages to being able to easily switch to a transparent BTC-style coin. First is lower cost. The transactions are smaller and easier to process. It is much easier for third parties to integrate it, since the BTC APIs are essentially standard. That includes merchants, exchanges, hardware wallets, chain explorer code, third party software, etc.

Anonymity is not one of the advantages, but that doesn't mean there aren't any.
