SDC is a DNM killer.

Hopefully the inner tech will be solid enough and the whole project a true success!

SDC was supposed to be listed for Chinese investors. Do we have any news about this?

SDC Is not a darknet killer at all.. I have invested in SDC  and expect it to reach 4 or 5 dollars maybe more if we are lucky.

There market is not going to be a darknet market, The devs are not even anonymous and if they allowed drugs on there market they are on a one way ticket to life in prison, the main dev is on youtube so anyone who thinks there creating  a dark market really!?

its going to be a little anonymous market with cryptocurrency exchange and a few services for sale.



$4 or $5 per SDC is chump change. The reason any coin exists, and grows is because it has a purpose. With SDC the purpose is multi-dimensional. Absolute privacy has always been a top goal, as is communicate, barter, and complete transactions in a secure environment. It has nothing to do with selling drugs, or illicit activity, it has to do with your right to privacy. There are always individuals that operate outside the law, and there is nothing the developers can do to prevent it, nor are they responsible for anyone else's actions. Once the market goes live I will be very surprised if SDC doesn't have a market cap well over $100 million within a few weeks or months. It is simply a matter of which coin offers the most complete package, and ease of use. Doesn't take much homework to see the obvious. SDC isn't some little kiddie coin looking for a fake pump, it's the real deal and is only going to become more stable and reputable...

And beyond that, what laws are the devs expected to follow? Drugs are illegal in some countries, Bibles illegal in other countries. Many countries around the world are human rights violators and their laws should be broken. It disgusts me to see commercial outfits in free countries stifling free speech and trade at the request of dictatorial governments in other countries and decentralized services are a good way to avoid that, no matter what else they might facilitate.

What advantage does a centralized DNM have over the Shadow market?

You might be misunderstanding the structure of the Shadow market. The devs do not "allow" anything on there. They write code. They release the code, and what we buy and sell there is what we buy and sell, they can't control any of it.

Besides the stake grinding mentioned above and other attacks that only PoS is vulnerable to, another issue is if there are only one or two exchanges controlling volume, and then an exchange gets hacked. If a hacker gets his hands on 10-50% of a PoW currency it sucks, and it's bad, but he can't attack the chain just by virtue of holding coins. This isn't the case with PoS currencies, where a hacker can basically control the blockchain if they get their hands on a large portion of the supply, either through an exchange or some other means. This led to the Vericoin/Mintpal rollback fiasco a while ago, and almost led to NXT rolling back their chain as well in one of the (many) Bter "hacks".

That's true, but if a person had control of that many PoS coins and corrupted the blockchain he would instantly make his own holdings worthless because nobody would want the coin anymore. Once a hack of that size was announced he wouldn't even have to attack the chain, people would be dumping like crazy until it's dead once they realized it was possible. if he were to buy enough coins to do this he would drive the price to the moon with his demand, very expensive for him and then what, turn it all into a shitcoin with forged blocks? Yes he could destroy the coin but he would destroy himself too, only someone very rich and insane could do it and everyone else who sold to him would profit from his loss before it happened. So I don't think that would ever happen.

Meanwhile you can get control of 50% of the BTC hash with 864165 TH. Miners are about $125/TH now, so for $108M you can control a network with a market cap of $10B. That's a 100:1 leverage, I like the odds of that happening a lot better.

Except you couldn't market buy that many miners. You'd have to like have your own chips fabbed, packaged, and setup your own warehouses to run them in, which may or may not cost more than 108M USD. But, your same logic applies, why would someone spend that much money to gain control over something that will then crash in value? Personally I think it's a helluva lot more likely to occur when some hacker can do it for (practically) free by hacking an exchange compared to someone spending hundreds of millions or more dollars creating the infrastructure to 51% Bitcoin, or in the case of other leading PoW coins like Litecoin or Monero or something maybe millions to tens of millions, still a lot more than what it costs to hack a website.

If you were Bitmain you could get that many miners, and they mine too. A PoW attacker has the advantage of not actually holding the coin, so if he destroys it he loses only his investment, which he can then use to mine something else or he can hold the blockchain hostage and make demands. A website hacker could attack PoS much more cheaply, but he would also make more money selling the coins than trashing the blockchain and ending up holding something he can't sell.

Also the community can do their part to prevent PoS attacks by staking their coins and not using the exchanges for storage. When the use of SDC exceeds the trading of SDC that will happen and there won't be enough coins in any one place to do what you are  talking about.

Why is it that POW coins are preferred more than POS coins? Newb here, just curious. Is it because one can profit more with POW mining? I'm holding some of both.

A few reasons, none of them really good. One is just tradition, Bitcoin is a pure PoW coin and I suppose in the days of CPU mining it was believed to be a perfect system, but now that every CPU in the world couldn't keep up with one big ASIC farm the imperfection of it is apparent.

Another is certain alternative political and social beliefs where interest/inflation are the root of all evil, it's all controlled by the you-know-whats and the rich get richer, all of that stuff.

Another is that there is less distribution of the coin when people can't mine, but I think that's a carryover also from the old days of CPU mining. Although another popular anon coin is CPU mined, we don't know how much of that is being mined by malware and distributed to just a few bad actors. It's happened to other good coins.

Another is a perceived risk of forged blocks, but I don't think that would ever happen being to do it you would need to buy an enormous amount of coin, only to summarily make your coins worthless by corrupting the blockchain and destroying the reputation of the coin.

This might be true, but I am also prefering PoS coins because:

  • They don't burn such insane amount of electricity just for the sake of keeping the network secure. PoS coins are much "greener" than PoW ones; I really like that (we're fucking up the planet enough as it is)
  • While the "rich get richer" is true, I still think PoS is more distribution friendly than PoW. In PoW nowadays, you need a massive budget to buy mining equipment (ASICs) and keep it running (electricity) to mine coins. In PoS, you just directly buy coins and that's it. I think this is more fair for people (meaning that the entry barrier to start mining PoW coins is really high and costly).
  • Regarding the inflation – I don't think it's such a big problem, when it's stable. If devs could change PoS rewards (inflation) as they would please, that would be bad of course. But this is not the case.

All in agreement. While they say PoS creates inequality of access, there is also inequality of access to mining equipment and cheap electricity. Although a CPU mine eliminates a lot of that, if Monero were to get big enough how long do you think it would take to make ASICs to mine that too starting the arms race all over again?

Interesting thing about SDC PoSv3 is that not every coin gets the stake so it is inflation for some uses, interest for others. The people who leave their coins on exchanges for rapid trading are paying interest to those who hold on their own machines, as are the people who hold them as SDT or actively spend them. Seems fair to me, the coin has value and value doesn't come without a price. It's about 7.5% overall return on staked coins now, subtract the SDC 2% inflation and you get 5.5% return before fiat inflation, not a bad investment even if SDC doesn't rise at all relative to fiat.

Forgot about that one. I can see the temptation to do a roll back, but as an investor it would be a complete turnoff. Unfortunately law enforcement doesn't take crypto theft very seriously unless it involves a regulated exchange that deals in fiat.

I agree, if a coin can be rolled back who knows what that will open the door to? Defeats decentralization.

As I understand it the devs had an even bigger loss from a tip jar, not clear whether it was theft or a mishandled wallet, but they didn't even attempt it when it was their own money.

You should always encrypt your wallet, and never download anything you don't trust 100% to a computer where you store coins.

That said, this hack had nothing to do with SDC. If the wallets were properly encrypted, the coin's couldn't have been stolen.

2FA works well for accessing secure online accounts, but it doesn't make much sense for a wallet that is in your control. I personally wouldn't want a 3rd party involved in securing my funds. It essentially takes the decentralization out of it. Like storing your money in a bank. If you want maximum security, you can always store your coins offline.

Absolutely! The biggest personal theft I'm aware of involved a fake wallet downloaded from a corrupted link.

Machines are cheap, most of us probably own several coins so you can dedicate a machine to all of them, get rid of the browsers and e-mail, lock it down, back it up, etc. Even if someone steals the machine, as long as you are backed up and encrypted you can be up and running with the coins moved to new addresses before they figure out how to turn the damned thing on. Don't let the bastards win!

Are you planning on putting in your recommendation the fact that you were paid to make the recommendation?

That's what it would take, with this crew. No phony stuff here, that's for the crapcoins.

That said, I don't think acceptance by dark markets is something to seek. Most of the DNM stories have been tragedies, leaving confiscated coins and ruined lives in their wake, and I predict the next major dump of XMR will be thanks to a FBI seized assets auction. Too centralized and too big a target, plus the cumbersomeness that comes with operating and using a dark site. It may be obsolete tech now.

Thats a one way of looking at it. Also keep in mind that Satoshi is in FBI's and several other agencies most wanted list. Shadowmarket, if it will ever become a popular demand, might cause troubles to their devs due to illegal trades going on. On the other hand its no secret that FBI decoded tor and watching people.

I think the devs are safe, being they have not a bit of control over what we do with our wallets or coins. This is why it's imperative that the wallets be uncensored, for once the the devs have the power to control what we do there will be a demand that this power be used. And being it's open source it would be easy enough for anyone who knows code to remove whatever they were forced to do.

Nice thing about the Aphrodite wallet is that it alone will make both dark markets and the eventual Shadow market unnecessary for some. Sellers can set up shop right in a chat room like they have been doing in IRC channels for years, with the advantage of a secure currency built in.

To clarify- the stake reward is always the same, about 0.268 SDC now. The larger your staking balance, the more often you will get that reward. If you have 1 SDC it will take on average about 3 years to get a reward. If you have 20K SDC it will take a couple of hours.

New SDC holders, please keep your coins safe, coin thefts hurt the reputation of the coin and of crypto in general-

Use only the wallet provided by the official site in the the first post of this topic, don't trust anything else.

Be aware of what is running on the machine where your wallet is running- don't use your porn machine or anything crazy like that. Dedicated machine is good, tor is good, locked down encrypted disk, back up your wallet to stick and/or CD and lock it away, you know the drill.

Don't leave coins on exchanges, they get robbed, same story every time.

TorCoin. You proof of work is throughput on the network, a little for a bridge or middle node and a lot for an exit. Your Tor service is also a wallet and either the sender or the receiver has to spend to transmit data, and the spend is distributed among the nodes that handle it.

Somebody needs to invent something like this! Maybe they could start with a cryptocurrency with zero-knowledge proofs, and then add distributed public key messaging, then other features after that.

That's actually a freaking clever idea.

The list of tor nodes is known so whenever a user would make a successful connection to a website it can start broadcast a acknowledgement of service which would be secured by a CPU PoW algo and the node is rewarded.


Another good starting point for the consensus algo would be the "DDoS coin" example.
 https://news.bitcoin.com/proof-ddos-malicious-consensus/

Well of course it's a clever idea- it's yours! Because I'm really talking about Shadow, but with some features added to make it run like a tor service and connect machines through the Shadow network. The part where it's monetized is already there.

I had a crazy idea last night about how to make Shadowsend messages invulnerable to future decryption by other than the recipient.

The weakness is that all nodes on the network receive all messages. So the spy could be receiving and recording all of them, unable to decrypt them now, but in 10 or 1000 years from now, maybe.

A one-time pad is a very old, low-tech, and unbreakable for of encryption, unbreakable because the key is longer than the message and using any of the possible pads can make the coded message decrypt to any clear message you want. The weakness there is that the OTP is a private key and both parties have to have prior contact to exchange the key.

So what if... when one wallet sends a Shadowsend message to another, it also send a OTP (also encrypted with Shadowsend), to the recipient along with a few hundred other random nodes, and the OTP is used in addition to the public-key encryption to encrypt and decrypt the message? Nodes other than the intended recipient would ignore it just like any other Shadowsend message. The chances of the spy intercepting both the message and the OTP are low, and he would need to defeat the public-key encryption on both to read the message.

In addition to this, all online wallets would randomly send out random OTP's to random nodes on the network, so most of the pads the spy would be intercepting would be garbage but he would have to decrypt them all anyway, not knowing which ones are garbage and which can be used to decrypt a real message.

Of course users exchanging very sensitive information are already able to send each other a pad ahead of time using Shadowsend, but having random wallets also doing it randomly would add a twist that makes it much more complicated to defeat.

The communication through the wallet is very important. I consider one of the biggest flaws of Bitcoin to be the inability to communicate with your trading partner or attach information to a transaction. It makes retail use cumbersome.

Of course we are going to have to wait to see Aphrodite to determine what it can actually do, and then there is the process of testing it in the real world, lots of independent observers who can see how powerful the anonymity really is, just like what we went through with the coin itself. But if the API is there, I foresee a lot of people writing their own applications to do their own thing with it.

I've made more money in crypto currency than I ever made in stocks. I got in very early on most of them. From a technical standpoint SDC outshines them all. It is still an undiscovered gem, and has given many of us an opportunity to accumulate at bargain prices for an extended period. I also like that this is a very rare coin.
I'm still amazed that SDC is as cheap as it is. I have advised my family and friends to own some, because in my opinion a few hundred bucks isn't much of a risk. As long as Ryno loves what he is doing, I have great faith in our future.




When do you expect the market to start treating it that way? right now, it looks awfully dead.

This is not a day trading project. The coin is intended for a future where SDC is the standard for confidential transactions, with a market built into the wallet which uses only SDC and allows users to bypass standalone dark markets, which have put a few people in prison.

I assume the devs have as much holdings as anyone and want as much as anyone to realize that future. I'll ride with them, in the back seat, and we get there when we get there.

Wasnt an interview coming out yesterday?  Huh

Actually everybody's waiting for Aphrodite, not the interview. But part of that was posted in a small video.
see decentralize.today

Aphrodite could be years away at SDC pace - so the interview is what Im waiting for.

Shadowcash has delivered more photoshop market videos - and less actual working product - than any other project Ive ever seen. Ever. I was one of the first investors. They issue roadmaps, change them and arrogantly mock anyone who requests an answer to the delays.

This coin has never once been pumped.

Hopefully soon though...

It will be a monumental moment to see the Dev talk about his project on camera.
"photoshop market video" there was no photoshop and you should dump you really should we don't want any non believers around here.
In the first 12 months of Shadow development the team dropped so many releases it was blowing minds rhyno even got voted dev of the year then for the last almost 12 months thay have been working on a market
the team does not get paid they survive on donations OB had a lot of funding and it still took them over 12 months to build the market lol with a team 3 or 4x the size of shadows and in the end our markets design is and will be better so it's pretty reasonable imo
your a joke mate the pace of sdc devs who are you? i never even see you comment here before, no donations no nothing if it's photoshop dump your shit and move on.

You can look back to see my comments before the anonymity was cracked. I lost interest shortly after. Sold 10,000 coins at the bottom. Who would have thought a broken project would recover? Has it really? I dont know, but I bought back in recently and I am seeing a similar pattern arising to the dumbfounded hopes and dreams all you newcomers. I voiced a concern. I may be wrong. Hopefully I am.

OK so you are an anonymous poster on a forum who may or may not have once owned coins, may or may not currently own coins, and has an opinion.

Devs- WAIT! STOP WORKING AND LISTEN TO THIS GUY'S OPINION!

There, just doing my part.  Wink

Seriously, if you want to make any kind of engineer or developer work on a schedule, you need to give him a contract or a salaried position. Then you get to tell him what to do and when to do it.

Only AVAST, no AVG
You try on free https://www.avast.com/  

Screenshot
http://imgur.com/gMZzKrx

Stoned.2(b) is a malevolent Trojan horse that that often makes use of system loopholes and Internet vulnerabilities to break into the targeted computer and damage the whole system.

Stoned.2(b) uses your network connection to download additional malware onto your system. This Trojan horse also opens a backdoor in the system, which allows the remote hackers to visit your computer and do whatever they like in it. Moreover, it will install a key logger in your system in order to record your keystrokes and send that data to a specific server. As a result, your confidential information such as online banking account usernames and passwords will be revealed to the unscrupulous hackers.


Network security is what I do for a living. 99% chance you have a false positive. AVAST used to be good software, but you can say that for a lot of anti-virus companies. These days I consider AVAST to be crap-ware.

To get a realistic appraisal try running it through https://www.virustotal.com/, or http://www.herdprotect.com/ (a few positives do not make it a virus).

For personal use I still like Malwarebytes the best, and run it in combination with Panda Cloud Free.

Never had any issues with SDC. Always make sure you download from the official source, because it is possible that someone might put an infected version out there.

Just for grins I ran my blk0001.dat through the latest version of Malwarebytes and Panda, and it comes up clean. I remember back in the day, all the mining software I used to run came up as a false positive, so I'm betting it's just another flaw in AVAST.

I've seen that too, might have been related to malware that forced infected computers to mine for someone else. Also employees using their company equipment for mining; security people used to find computers stuffed full of GPU's and hashing away overnight.
