[ANN][JPC]MAKE JACKPOTCOIN GREAT AGAIN!

[rsclark3]

Is there a working CPU Miner?

There's a download link on page 1 for the compiled version. The Github files are here:

That one is broken, it says 'zlib1.dll is missing'. If I use zlib1.dll from another miner then I get another error.

[ReiMomo]

Wait, I found a zlib1.dll from the X13mod GPU miner that works, is 111 KB,

Daaaang, look at that 18btc buy support! Please dump you lazy JPC holders

At the current price, JPC is a (speculative) steal. If a new dev can be found, and there will finally be some new features, the price might go back to 10s easily.

hm...I just set up a new machine (ubuntu 14.04 server) where I wanted to install the jpc client. Compiling wokrs fine, but I cant start the wallet:

Code:

JackpotCoin server starting
JackpotCoin: Error initializing database environment /home/user/.JackpotCoin! To recover, BACKUP THAT DIRECTORY, then remove everything from it except for wallet.dat.

Any ideas? It's a completely fresh system, no blockchain is there.

ah, no - the problem was berkeley db. It selected 5.1 where it seems to need 4.8. After compiling with 4.8 again, it starts immediately.

I'm syncing since my last comment. Currently @ block 1949171. This definately needs to be improved. At least add tags to git so I can checkout a different version :-)

Yeah it's getting pretty big.  Lots of transactions to process.  I kept the chain backed up when I swapped to fresh wallets before and it cut down on sync time a ton.  What seemed to bog it down were addresses I had used since the launch and all the history attached to them even though they had 0 left at the time.

Hi, this is miningpoolhub.
We want to make a proposal.

Extend the PoS target time.

Currently PoS difficulty is too low, too many clients interfere and make orphan blocks.
And block height is growing too fast, sadly almost blocks don't include normal transactions but only mining transactions.

jackpotcoin daemon on our mining pool server itself consumes more than 1.5G of memory and 100% cpu for one core.
Memory consumption will increase day by day, since unspent transactions are growing fast. This memory consumption is even bigger than bitcoin daemon.

We are seriously considering to remove jackpotcoin pool since it really hurts server resource.

Any idea?

@2246093 wow...

@miningpoolhub: I agree. It's important that all this resource hungry stuff is being removed. The problem seems still that there is no new dev.

@jackpotcoin: How are things going? Any news?

[liomojo1]

I am syncing ok , but when i try to send coins to anywhere it says error to load the transaction?
Anyone with a suggestion?

Fiexed: just use small amounts!!!

My wallet since yesterday has a note "WARNING: Checkpoint is too old. Wait for block chain to download, or notify developers." I was still able to send JPC to my wallet at an exchange, and it shows up there fast as usual. The only catch was that I also got the message "unable to send transaction." I thought I might have started on a fork of the blockchain so I sent a few smaller transactions (less than half the JPC amount in my wallet), and the transaction sent just fine. I successfully sent all my JPC to another wallet, it just took smaller transactions for some reason.

I'm with miningpool regarding the size of the block chain. One of this coin's greatest strengths is speed of transactions, but there should be some way to address how huge the block chain gets to support this speed.

PS I've been solo mining for a few days. Now that the pool is off line, the blocks are a lot easier to find. It's kind of funny that miningpool mentioned orphans. They were such a large part of the mining community that I would get lots of orphans before they went off line. Over 10%. Just the nature of the game if someone else gets a block in the block chain slightly ahead of you I think.

I just checked explorer.jpcpal.com and my copy of the block chain is consistent even with the "WARNING: Check point is too old..." message in my wallet. Looks like I'm mining and finding blocks. It's a great time to solo mine with the difficulty so low.

Happy One Year Birthday JackpotCoin!!!

I cant get my GPU rig to solo mine.  What is the URL and port for solo mining?   Thanks, appreciate it.

I remember mining this coin about a year ago and hitting the jackpot. It was like $150 or so.

Too bad this coin is dead.

Same as every other coin, it's defined in the conf file in Jackpotcoin folder.  Can't go into detail now, but there are plenty of guides for solo mining around.

I also get the message:

Code:

since the wallet is (finally) fully synced. However, transactions are working and are fast as usual.
