HI, do you have any nodes?

CPR is now listed on unnamed.exchange
https://www.unnamed.exchange/Exchange?market=CPR_BTC

cant some people open their wallets to help the blockchain a little? Don't want cryptsy going on its own fork and running away with the blockchain and a private website block explorer.. 

It would be a sweet feature with a multi desktop wallet, thought about it many times too...

Almost every ALT coin was created by some scam group. I am coin collector, I collect small amount of dead/oversold dying coins, even scam ones. Those coins are dirty cheap compared to bubble price, so I believe sooner or later their price will grow doesn't matter how dead they are or how scammy start they had. Coins created in 2013 and earlier will have at least some historical value. And since Cryptsy decided not to delist dead coins their time can come back on any bubble and they are not dead yet. Once Cryptsy dies, it will be alt coin biggest grave. Until than, there is still some hope:) Also I am thinking about creating some universal alt coin wallet, so people can move their coins out of cryptsy without installing every single wallet. But it is just a dream now:)

pretty cool op~ 

OMG...this coin is dead

take it as a warning to stay away from anything igotspots is associated with?  
his current coin is snowballs and he will probably abandon that in time and start a new coin.  who knows how many times he has done this already.  exchanges should stop adding any of his coins

Copperbar wallet works fine afaik, could use some updates and new features imported.   I've noticed there is a number of coins on cryptsy with wallets in maintenance for a long time now, while wallets/blockchain are healthy.  so either crypsty is being lazy again or for some reason are (mis)using maintenance as a way to prevent withdrawals.

What is the status of this coin? It is still on Cryptsy, with defected wallet. Is there still anybody interested in this coin? It seems it just need some working wallet update. Is there someone mining it?

CopperBars now has it's own page on http://coinwik.org a wikipedia listing all the alt coins to help you quickly find facts and links about your favorite coin.

If you know of other facts and links that can be added to the page, please feel free to update the page.

I didn't look into PoS too heavily. Considering most of the code appears to be a direct yacoin fork with the bare minimal alterations to function, and their PoS still works, I'd expect it to be alright. The real problem, is the orphan problem. Without a DNSseed, longer block/retarget time, etc, this will remain a large problem. Its something that could easily be fixed via a hard-fork, but the only real way to get that to happen is for cryptsy to agree to fork their wallet as well. (Make the money fork, and the miners follow). If it were hardforked, could also include coincontrol, and look at PoS pretty easily at that time as well, but as I say, both those features are luxuries compared to the orphan issue.

When trying to rebuild the database -- it will be stuck on the splash screen for a long time, and be "unresponsive" (I.E. if you click the icon, or splash icon, windows will tell you the program is not responding, linux will do nothing -- this is why I recommend running with logtimestamps, so you can see it is still adding the blocks from disk. Its painful either way, but atleast rebuilding isn't too bad.

Technically you should be able to interrupt the process and resume it (as it will likely take 100% usage from a core, and significant disk usage), but as there is no way to "cleanly" exit, you do run the risk of corrupting the new database. FWIW, when I reindexed on my WinXP laptop for testing, it kept going to hibernate, and would wake up and resume indexing w/o issue.

Both prebuilt binaries I've posted (Windows/Ubuntu) contain the respective most recent version of openSSL, which fixes heartbleed. If you built it yourself, it will use whatever you have installed.

Big thanks for this, its needed an update for so long.  I will give a try but as you said maybe see you in 2 weeks,  i will try the 2nd method first and hopefully save some time

Were you able to check that the PoS part is correct and will work as expected, this is something i've been wondering about seeing as the previous update was before many of the PoS coins last year began to break or did weird things (eg pennies, starcoin) and igotspots may have not hav fixed or even known about it.  and can we assume it also has the updated ssl to protect from heartbleed?

I'd mined this coin back during launch, sad to see it has been so forgotten.

Since the dev seems to have totally abandoned this project (and doesn't reply to PM's), I've gone ahead and updated the source a bit. It now starts MUCH faster. As a result of this however, the way the database is handled has changed, and it will require the database to be rebuilt (see below).

Code, with Linux & Windows pre-built binaries included is at https://github.com/maelstrom987/CopperBars

For Windows users - head to the release folder, and download CopperBars.exe. This was built using msys and minGW. The .pro file used to build this is included, and can be rebuilt yourself if desired.

For Linux users CopperBars QT is already built in the main folder, built on Debian 13.10 for me. You'll probably want to rebuilt it yourself.

As far as what's changed - There were many minor changes, but the big ones were as follows:
Updated net.cpp code to allow for more total connections, and to accept to the -maxoutbound command
Updated main.cpp, checkpoints.cpp to allow for a faster startup (basically used a newer yacoin fork)
Updated checkpoints.cpp (but only testnet) to include a handful of checkpoints for what appears to be the longest chain. These are not currently used, but may be helpful if someone wants to verify their chain. If there was actual interest from people still mining this coin, I'd make them included in the launch version.

Finally, a note about rebuilding the database - When you launch this new version, it will tell you that there was an error loading blkindex.dat. This is completely normal, and it has not corrupted your blockchain.
At this point, you have two options:
1) Redownload the entire blockchain (see you in 2 weeks)
2) Backup blkindex.dat, blk0001.dat somewhere safe.  Make sure they are out of the config folder. Delete everything except wallet.dat and CopperBars.conf (or similar named) from the config folder. Preferably, add logtimestamps=1 to your conf file, or launch with -logtimestamps. Then, add loadblock=C:\blk0001.dat to your conf file, or launch with -loadblock=C:\blk0001.dat (assuming you have placed a copy of your original blk0001.dat at C:\, change the path to wherever you've placed a copy of this file. It must NOT be in the config folder)

Method number 2 will take anywhere from 3-40 hours to complete. My 4770k with Raid 0 SSDs clocked in at about 3 hours running Win7 64. My old clunker with a Q6600 and 2GB of ram running debian off a thumbdrive took close to 40 hours, while other PCs/mining rigs I've got took somewhere in between. This is why I highly recommend launching with logtimestamps, so you can see that it is still working by loading the log file. It will also tell you what block you're on. At the time of this writing (10:00AM CST), I currently have 1474746 blocks. After this first launch, remove the -loadblock line. After this, the client will launch within a minute, at most for most machine.

I also have a private pool running, which I may make public if there is any interest -- it does appear to suffer from the same orphan problems that were there when this coin launched, though part of if is that there are so few nodes that have listen=1 enabled and are actually connectable, so it is difficult to propagate a block quickly.


Hope this helps others who are still giving this coin a look from time to time. Feel free to PM/Post with questions.

i need nodes, can't get my wallet to work.

I think most are solo mining this coin.  You could try and see, alot of these older and neglected coins are easy to solo mine now

Hello

where are any Copper Bars pools? I can see only 2 of them dead: botpool.net and coinmine.pl
Is there any working pool? Pls hlp!

Seems there is not that much activity going here , but is the dev and the community still around? Doing some prospect work around right now

This would great to see happen,  its really could use some additional exchanges

A wallet update would be another excellent development either from original dev or someone else who with the talent to do this.
It only needs latest updates/patches from bitcoin/litecoin since the last update, wallet optimizations -fix the slow startup and new wallet features such as coincontrol surely someone out has the talent for doing this. It doesn't need them but it would be nice
