I'm also seeing "Mandatory Upgrade to Litecoin 0.8.6.1+." everytime I start Junkcoin-qt.  Anyone have a solution?  I have already upgraded my litecoin wallet but still see this message in Junkcoin.

The pool has moved. The new address is

www.coin-base.org/jkccoin/

All your data and coins were transferred.
You must only change net to org.

There are now three different Stratumports with different difficulties.
Port 3457 for slow Miner - Pool_target 16
Port 4457 for normal Miner - Pool_target 32 (one share is two Poolshares)
Port 5457 for fast Miner - Pool_target 64 (one share is four Poolshares)

Pool Down ^-(

As scheduled the new node is up and running.

# Permanent Node for:
# YKC - Junk Coin
addnode=5.249.152.30:9771


The winds for the new Junk Captains are positive, so lets' get some coins LOL Smiley

The node is down due to server upgrade.

I decided to start to provide the node in a better level thanks to so many connections, so
I get a dedicated server to do so.

A get a Dell R210 with 4 Xeon cores 16Gb or RAM and 2x450Gb15K HDD configured in a Raid 1,
a OK machine to provide better Junk Node as well as other coin nodes.

The update is also at OS level where I'll switch from Windows to Linux (Ubuntu) OS, no licence and a chance to get a deeper know how from that switch too Smiley.

If anything goes as scheduled tomorrow night (european time) the node will be up and running again with the following new IP:


# Junk Coin Perpetual Node
addnode=5.249.152.30:9771






HI HO Junk Miners Smiley

I setup a node for JunkCoin network.

At least we can update the block chain, transfer coinz in less than a decade and who wish to mine can get some confirmations Wink

LOL Smiley

I see with VERY BIG SATISFACTION that community has respond to the new node VERY VERY WELL Smiley

From yesterday I have about 50 connections/peers on the node, while in saturday whan I just post the IP of the new node I had hard time to update my block chain that now all the connected peers are sharing, that's AWESOME LOL Smiley

I'ts incredible how a little bit of work can change a whole market LOL Smiley

The price probably dropped because when you added that node people mined and dumped the coin after they mined a few.  Without any kind of base for the coin - the reason why you had to add a node in the first place - miners are just going to mine the coin and then sell off what they mined.  No one is mining the coin and keeping it, waiting for the price to rise.

No mined coins, the block chain time stamp is fixed at "mar 5. nov 03:34:00 2013" Sad

I think that people who had Junks in home port now that the blokade is over had take the wind and start to move tham to market.

Acting with stategy "what is in, is in" thay are ready to sell all Junkz for a forth of the real price, so that's why, from my opinion the price dopped.

Well now that the market is again sailing with good winds I bought some Junks just as investment LOL Smiley


I'm organize myself to provide more nodes, I'll get more servers and I'll help the crypto community to survive.

I don't like the fact that people loose their time mining a new coin and than after a developing team scrue up thay lose not only the mined coins but all what thay invested in getting tham as money to get hardware, energy to power the miners and most important of all REAL LIFE TIME that will NEVER come back and no BTC will pay for it Wink

I have to start my MultyNode Project Wink

Why??
Because I know how, because I can and because I like it LOL Smiley

It seems that people like the new node, 50 +/- and counting LOL smiley.gif

Lets put some more sailors on those Junks, a?!?!?!

LOL smiley.gif

It's nice to see how many new trades are availabele now on Cryptsy after the NODE setup, maybe the NODE makes the difference LOL Smiley

Unfortunately the price has dropped from 0.00040000 LTC for 1 JKC to 0.00003 +/- Sad

But whan people will see the stability I hope the market will bust again Wink

Hooray for non-equilibrium thermodynamics!
I thought it might have been talked about before, yup.  But I couldn't find the list.   So I made a new one Smiley

The Luckycoin method of using part of the previous Hash to generate a seed is a bit better.  Then you can only predict 1 block ahead.

Are there any other JKC clones that kept the nHeight seed?  I've only seen it in Sexcoin so far.

Not sure I'm afraid. I have to admit that I got a little fed up of trying to keep up with the barage of new coins a few weeks back. I haven't looked at the code for many of the more recent ones.

Has anyone made a list of all the past and future reward blocks of Junkcoin?  

This seems like an easy list to make, because the Mersenne Twister is seeded with the block height.  Thus we know the seed for every block, past and future.

main.cpp
Code:
	int rand = generateMTRandom(nHeight, 100000);

It seems it *is* possible.  So I make these predictions:

Quote
Next *3 block: 90316

Next 1000 block: 91460

(current block 90297)

You're right, it is deterministic based on block height (which is known in advance). It's been mentioned in the past (e.g. https://bitcointalksearch.org/topic/m.2362053 and associated posts - including a mention from fisheater about a table of superblocks somewhere, which I haven't seen I'm afraid). Nobody seems to mind too much, I guess because you'd still need to win the block if you knew it was a super block. However, with a low hashrate on the network it is more of a risk that somebody with a lot of hashpower can jump in and mine the super blocks. Luckycoin overcomes this problem by using a seed generated from the previous block's hash, which isn't known in advance.
