I knew there was a reason I quit reading this thread weeks ago. I came to catch up and all still the same Ego's and infighting.
No one owns black coin, neither Iconic or the "foundation", so everyone should quit fighting about who is in "control" of this coin. Everyone who believes in the coin is free to promote it however they see fit.
All the fighting is nothing but a distraction and detracts from any positive efforts.

Re: [PRE-ANN][SHA-3]*******Black Black Coin*******[BBC][50%FREE CON][50%Mining]
Sorry I realized after that there are 2 similar coins! 
A BBB (black black black coin), the other is the BBC (black black coin)!!!
Very similar with almost identical names!
As soon as the BBC wallet will be available, I will insert the correct address!
p.s
other similar: BCC (Bitcointalk)
Abbreviations are similar very easy to confuse!

Who is making blackest coin to put a stop to this?
I was asked why blackcoin is so unique, besides pos. I was going to mention the fast transaction times, but some think this is just a simple mod like litecoin ? Seems impressive to me but is there any other utility this coin brings that I could say in defence of the realm of bc
None that I'm aware of and when I mentioned that BC really is just another scrypt coin in the chat, I sure caught a lot of flack! lol, I wasn't trying to insult anyone... but there is some crazed BC fans in there,,, hey if the payout is good I'm all in, I am considering outright buying some BC along with mining concept BC PoolA nice discussion of what really makes blackcoin stand out.

This bubble popping is a good thing. We want real organic growth not pumps. The community is still strong and the coin is still up 600% from a couple days ago... Coin kite is still months away, and by then the value will be much higher. Don't panic on market turbulence, best strategy is to buy, mine, hold. This coin is only going up long term.
The BC price is unbelievable! What is causing this?
This is a great coin and community. Fair release, no premine, super fast transactions, and low inflation. Already has been announced that coinkite will be adding it, moolah adding it to merchant services.
The coin is still way undervalued. BC will be a top 5 coin, and some people have started to realize it.
Price may consolidate a little in the short term, but this has nowhere to go but up... give it 6 months and see where we are.
Sellers will be punished - ask those who sold yesterday at 16000 sats to take profit.
I'm a proud BC bagholder since day 1... and will be holding until 1BC = 1BTC.
CGB community, today is a big day for the Vault of Satoshi as they conduct a Ask Me Anything (AMA) session at 1pm EST in accordance with a fundraiser for cancer research! This is an excellent cause and the VoS is a friend to CGB. Please get involved in this today and show your support via participation and donation! And of course help to spread the word via social media. Lets give VoS a strong showing of support from the CGB family as they work on this noble cause today! BTW, they accept donations via cryptos and the CGB tipbot is activated so load it up and get ready on Reddit!

Sorry guys, the tipbot was banned from /r/IAmA... I'm not sure why. Anyway you'll have to donate to the CGB address they listed instead of using the bot.
Is it just me or is the distribution of coin holders looking way better than a couple of days ago? Would be awesome if we could plot the top 1000 distribution to see how fair it looks.
Looks like a few large holders have offloaded and there's a more even spread on the bottom end now.

I have on this page only 22k what is not true
Go to your debug console and type listaddressgroupings there you can see the other addresses that hold your coin. These are automatically addresses created and used for change and staking.
This has nothing to do with Blackcoin. Which is why I am against any posts which presuppose the culpability of consuming energy. Let's not deceive ourselves, the primary detractors of Blackcoin are the Mintcoin people. Or Mincoin eco-fags, as I prefer to call them.
I realize that the average person here has the average understanding of eco-propaganda. They swallow it entirely.
I also realize that the average person here has the average understanding of homosexual-propaganda. The two are linked. No, I don't care what people do with their genitals. But it is very clear that those who control the global economy, the Bilderbergers, Rothschilds etc, have actively promoted homosexuality and abortion as a means of reducing the population. No, I am not a Christian. This is just a fact.
The ecology movement has been coopted at least since the 60's by the very corporate interests that the left wing complains of.
The absurd claims that the oil industry, the Koch brothers, and other bete noirs of the coopted left are in some coalition to ruin the planet are a lie.
Global climate change is the least of your worries. Global takover by politically correct garbage is serious.

Virwox will work to get from dollars into cryptos, using paypal or credit card, but you will pay a high price in fees and have to deal with multiple exchanges to get BC.
coinbase and localbitcoins are great services to get your dollars into bitcoins and usually can get you bitcoins the same day, but then you will need to move them to an exchange to get BC...
Prelude.Io will allow you to buy directly with dollars, but you have to be verified and you need to make a bank wire transfer or go to a wells fargo bank and deposit to their account. also you will find not a lot of volume there so you will probably pay a high price if you can even buy the amount you are looking for. (Please people consider buying and selling even small amounts of BC on prelude.io to help with this! More volume trading there will also encourage them to add BC to their other services including payment services and coming soon ATMs)
all of these options make BC adoption a bit difficult for the average person who is not already versed in cryptos.
This is what we as a community need to work on, and it is not an easy problem because of financial regulations, but one we will have to face at some point if we want BC to continue to grow and someday rival BTC.

Re: Security analysis of PoW/PoS hybrids with low PoW reward
Isn't it true that most PoW/PoS hybrids have the same target block generation speed for both systems? So why would there be many PoW blocks in a row unless it happens by random chance?
If the difficulty is very low due to low network hash rate then applying a substantially higher hashrate can cause many POW blocks to be generated quickly, much quicker than the target rate.
Re: Security analysis of PoW/PoS hybrids with low PoW reward
That is YOUR reply I quoted.
You must have read the answer at one point, because YOU commented that your question was answered, but I will summarize it again here just to be perfectly clear.

- Blackcoin use POS 0.3.0 protocol which has no known vulnerabilities at this time
- The "attack" suggested is impossible because coins do not stake on age alone, therefore making deposits at small intervals in no way guarantees you will generate POS blocks at those intervals. In fact splitting coins to generate these intervals will make the chance of staking at each interval even less
Right, it uses "POS 0.3.0 protocol which has no known vulnerabilities at this time" in the context of a PoS/PoW hybrid, right? It has never been tested in the context of pure PoS, right?
I will restate: If i said said anything further about it on the blackcoin thread, I would have been ran out of there and labeled as a FUDer.
Similar to how what I am saying now, not on the blackcoin thread, is drawing so much heat.
I'm not giving you heat, i'm only answering your question.. again.
Saying Sunny King's fix only applies to POS/POW hybrids is incorrect, it fixed the POS protocol. Period.
The timebomb attack is not feasible because coins do not stake on age alone, there are other factors. Even if you could guarantee that all your coins ages were spaced at a minimum interval there is no guarantee they will all stake at their intervals. Also POS blocks have a target time interval, so coins that were eligible to stake too soon would not generate blocks any faster than the target interval, there is no way that one person could force their coins to be the ones to generate stake for many consecutive intervals. This attack is pure nonsense.
But Sunny King fixed PoS in the context of PoS/PoW hybrid, not pure PoS. Right?
Since there have not been any other pure POS coins yes the fix was originally applied to a POS/POW hybrid. Nevertheless the fix is for the POS protocol and did nothing to POW. The fix ensured that POS was a secure way to generate blocks to secure a blockchain. If you know of any vulnerabilities in POS please make them known so they can be addressed.
I don't know the specific vulnerabilities, I'm not saying that there necessarily are any. My argument is purely from a logic standpoint. If the security of PoS was in any way dependent upon PoW in the PoS/PoW hybrid system, then just because the PoS security flaws were fixed in that context doesn't mean they will be fixed when PoS is standing alone, or that new security flaws wouldn't be introduced when PoS stands alone. So the question is, did Sunny build/fix PoS to be completely secure standing alone or was it in anyway dependent on PoW? I guess this is ultimately what I am trying to figure out.
Sunny built them to be dependent on each other. POW is a proven system. POW/POS is a proven system. POS is not and may be vulnerable to attack.
OP's point is that a POW/POS system with very small rewards creates a weak POW system that someone could exploit and it would essentially be the same as a standalone POS system which may be vulnerable.
You clearly did not understand the OP. That is not the OP's point at all. The OP's point is that POW/POS hybrid is vulnerable to a double spend attack by a POS block negating/orphaing a POW chain with enough blocks to have confirmed transactions.
I expect you have never looked at the source code of a POW/POW hybrid, because it it very clear POS and POW are not dependent on each other in any way. They are completely separate methods. It is true that POS only has never been tried before, but the POS system is secure in itself and has no known vulnerabilities. POW is a proven system with a known vulnerability called 51% attack which is why POS was added. POS/POW may be vulnerable by the method explained in the OP. POS alone, again has no known vulnerabilities besides a 51% attack which would require owning 51% of the coins which would mean you already basically control the money supply and would devalue your own coins.

POS and POW are completely separate and different systems. They do not depend on each other at all. They work separately and can compliment each other as 2 different methods to secure a block chain or they can each stand alone.

Re: Security analysis of PoW/PoS hybrids with low PoW reward
This is a joke. Nice try to spread FUD about other coins, rat4, to try and promote your pure PoS blackcoin. How is it that Blackcoin prevents attack forks as a pure PoS coin, again?
You say "a sequential chain of PoW blocks can be mined in a flash."
Which is not true. Sure, you could mine all of the PoW blocks that occur sequentially, but there will be many, many more PoS blocks that interrupt those far and few apart PoW blocks. In a PoS/PoW hybrid there is no way to predict or control whether or not the next block will be PoS or PoW and therefore you cannot guarantee you will be in control of a long stream of blocks unless you have 51% of the PoW and PoS power.
Now, this brings up an issue with pure PoS coins such as your Blackcoin... That I have yet to be seen answered in any technical detail. How, when it is pure PoS and it IS known that every block in a row will be PoS, can you prevent an attack such as the one anonymousg64 brings up:
Without PoW blocks to interrupt such an attack, how is it prevented?
This thread of yours is in really bad taste, rat4, you should find better ways of promoting your coin.
I await your reply, and your explanation as to how PoS coins are safe from a TX/coinage attack.

If you have thousands of confirms it should be done staking, it only take 510 confirms. Can you post a screenshot of your transactions page? Does the stake transaction have a clock by it? Or a checkmark? Or a questionmark?
Go to the debug console and type checkwallet and see if it replies
{
"wallet check passed" : true
}
If it is false do repairwallet.
