[ANN] [PPC] PPCoin Released! - First Long-Term Energy-Efficient Crypto-Currency

[kingmidas]

Hello!

I have some issues with my ppcoind server. I got a 'segmentation fault' error almost every day. How can I fix this? I have other alt-coins servers running and they don't have this issue. What should I do?

Thanks!

Are you using the official build or your own build? If you can get the core and use gdb to see if we can get a stack on it.

How do I compile the PPCoin GUI (in the qt directory)? 

'getinfo' results in 'checkpoint is too old'.  Why would this happen?


Thanks in advance...

[Vitalicus]

checkpoint is too old

WAIT

[Sunny King]

Typically 'qmake' and followed by 'make' in the top directory (not src)

During initial download it would show this message. Check whether you are connected to any peers and give it some time.

I downloaded it from the official website. I use the linux version "v0.3.0ppc-beta".
Thanks for the quick reply :-)

i have a very important question that is quite pressing to me.

i can't find a debug screen (like in bitcoin and Litecoin) in the PPC client.
How do i access it if it is hidden somewhere else, and if PPC doesn't have a debug screen, how can i get to know my private keys?

I'm clueless at the moment, help would be appreciated!

anyone?

The current version of PPCoin is based on a version of BTC before the debug/console window was added.

You will need to use the command line ppcoind daemon to get/import private keys:

In Windows ppcoind is normally located in C:\Program Files (x86)\PPCoin\daemon   or   C:\Program Files\PPCoin\daemon   if using a 32 bit version of windows.

Linux is essentially the same instruction wise, except one only needs to start the daemon once with the --daemon switch.



Quoted from a post of mine in a older thread:

With Windows you will need two command line windows, one to start the daemon in and the other to issue commands. You could also start the GUI version, and open one command line window to issue commands.

Window handles the daemons different then Linux. If you start a daemon in the command line window, it is essence becomes that command line window, unlike Linux which will put you back at the CLI if you use the --daemon switch.

So with either a command line window running the daemon or running the GUI version with the server=1 option in the ppcoin.conf, start a command line window in the ppcoin daemon directory and just type in:

ppcoind <command>

The commands for import and export of keys:

ppcoind importprivkey <private key> [account name]

ppcoind dumpprivkey <account address>

If you have an encrypted wallet you will need to unlock it first with:

ppcoind walletpassphrase <password> <time>

The time is in milliseconds, and lock resets when the daemon is shutdown.

thx, but i can't really get it to work.
If i open the PPcoind file the command opens and closes right back up after a flicker of text that i can't even read.
I've tried opening another command but if i type ppcoind help it says that that command isn't recognised.
I'm not a computer expert so i don't know what i'm doing wrong

My PPC directory is located on my D:\ disk and command starts on C:\ by default. Anyone knows how to change that so i can find the file that way? CD.. doesn't work

Open a command window by entering cmd in the start menu search box.

enter d: on the command line to get to your D drive

Code:

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Users\Robert>d:

d:\>

The easiest way to get setup for command line entry in windows is to add the : server=1 to your ppcoin.conf file located C:\Users\<YOUR USERNAME>\AppData\Roaming\PPCoin.

Start up the PPCoin GUI and open a command line from the search box.

cd into wherever your PPCoin install is and get to the ppcoind file. You should be able to enter commands like outlined above.

[Bytas]

well this is a painfull process...

I got it to work eventually but it's just a pain in the butt overall and not pleasant and easy to use at all.
A lot of things are really impossible to think of yourself and there is no documentation readily available.
Thanks for the help dreamwatcher!

@Sunny king: I think this adding the debug window should be on your todo list for the next update Would be awesome!

So are there plans to implement getblocktemplate so that we can use unmodified stratum server to connect?  Or are we forced to use TheSeven's forked version of PPCoin to accomplish this?

[Sunny King]

ppcoin will be refreshed to bitcoin 0.8 in the next couple months. Before that happens you'd need to use patched version to run stratum pool.

[TheSeven]

My patched version should behave just like bitcoin's getblocktemplate. However there are some changes in the block and transaction format of ppcoin that a stratum pool server needs to be aware of.
This means that you will still have to use ppcoin-aware stratum servers (such as slush's one with my patch), even with a future ppcoind version based on bitcoind 0.8.

Of course none of the mainstream media is reporting on ppcoin's energy efficiency design yet, while looking for all excuses to demote bitcoin.

But for how long would they hold the bastion?

The problem is the major bitcoin media themselves are shortsighted and not reporting on ppcoin's energy efficiency design either.

bitcoin people you need to understand that we are in this battle together.

I posted a comment about PPCoin on the Bloomberg article.

I also think this is a great except from said article:

[With Bitcoin] The trade-off here is that as virtual value is created, real-world value is used up. About 982 megawatt hours a day, to be exact. That’s enough to power roughly 31,000 U.S. homes, or about half a Large Hadron Collider. If the dreams of Bitcoin proponents are realized, and the currency is adopted for widespread commerce, the power demands of bitcoin mines would rise dramatically.

I will quote that in future when spreading the word about PPCoin. Cold hard figures like that really backs up why PPCoin is a great idea.

[stdset]

I'm trying to better understand how PPCoin works. Most likely what I want to ask was already asked, but the thread is very long, not easy to find an answer.

The question is: How POW and POS cooperate in PPCoin? 6 blocks/hour target frequency: is it total frequency of POW and POS together. Or is it only for POW? Now POS blocks seem to be much more frequent than POW blocks. Does that affect POW difficulty?

In my humble and maybe totally misleaded opinion it is okay to stay under the radar. Not much marketing needed, the concept stays for itself. Mainstream media is still doing the mental work in processing bitcoin and the possibilities of such a new thing like crypto currency. bitcoin itself stayed under the radar for nearly two(?) years.

And the general mainstream bitcoin community has to process the fact, that - in my humble and maybe totally misleaded opinion again - the mainstream economists are right in some aspect of bitcoin: It is not useful as day-by-day-currency. Its strength (and intrinsic value) lays in the storage, hiding and transportation of wealth. And this qualities stand and fall with the resilience against a 51%-attack. From my gut feeling, this attack is already being planned and prepared right in the moment.



(On the other side these economists and journalist are whining for central state control. This is, of course, not acceptable (to me).)


It is not necessary to "hold the bastion". The principle of crypto currency and its usefulness is now discovered and prooved and will not go away anymore. Like the wheel or book printing. (That's is not totally correct: If the establishment succeed in the breeding of the slave race and in the elimination of the rest, no one will be able of thinking self-reliant about crypto currency. But in this case there are other problems to handle than digital currencies).

In my humble and maybe totally misleaded opinion again, I think, the best way to hold the bastion is make ppcoin better on a week-by-week base. This also includes the small details - like the name or that there are still strings containing "bitcoin" instead of the real thing. Then it will be ready as safe harbour, when bitcoin is under heavy attack.

Some more easy-understanding documentations about what to do to get coins by holding them. How the difficulty and the block rewards are calculated. I am still desperately - - looking for that information.

ppcoin is open source. (Is it?)

Statement Regarding flibbr's Accusation of Large Premine at PPCoin's Launch

In response to: https://twitter.com/flibbr/status/323718244210982912

People should really do some research. There are a lot of misinformation bandied about on the web because some altcoin fans just can't handle competing fairly and squarely. I hope the creator of flibbr would realize that he was fooled by the false rumors.

ppcoin was pre-announced on August 10, 2012 in

https://bitcointalk.org/index.php?topic=99735.0;all

block chain officially started on August 19, 2012 in

https://bitcointalk.org/index.php?topic=101820.0

That's 9 days of notice to the public before release, with precise release schedule, and announced right here on the most populated cryptocurrency forum, rather than some obscure place. Check out all the other altcoins, I bet you would find that we had one of the most fair launch of all altcoins, if not the most fair launch. PPCoin has 0 premine (even genesis block has 0 mint), 0 taxation. Difficulty started at 256, unlike many other altcoins which were started with very low difficulty. Difficulty adjustment is continuous, which means there were a lot less number of low difficulty blocks.

Some people like to point out the high mintage in the first few days of the launch, this is another misunderstanding. In the first few days of any publicly released cryptocurrency the mintage is going to be relatively high because difficulty is low and lots of miners would like to participate, causing blocks to be generated much faster than usual and resulting in high mintage per day. Unlike most other altcoins, we already tried to mitigate this by starting difficulty at higher initial value of 256 and also further reducing the number of low difficulty blocks via continuous difficulty adjustment.

There are other accusations that our minting algorithm is unfair, as we didn't wait 4 years before the first halving occurrs like in bitcoin. First, our algorithm is another innovation to demonstrate that hard cap isn't required to guarantee scarcity. I am a cryptocurrency architect designing for real innovations, not out to copy bitcoin's design. Our design eliminated the sudden halving that artificially impacts the mining market. A gradual reduction in mining output is a necessary guarantee of scarcity, while providing somewhat more incentive for investors. People are often jealous about these 'early adopters', failing to realize that without their participation and enthusiasm the project might not even reach the current state. As a designer I must carefully balance all these aspects. The mint reduction rate is carefully chosen so it matches bitcoin's mint reduction rate in the longer term.

I hope this would clear a lot of misinformation regarding ppcoin. We have always tried to hold us to the highest professional standard in the industry. This is in fact shown in our handling of ppcoin's launch. I sincerely thank our supporters helping to clear our name in the market against the malicious misinformation thrown on the web.
