JKC - The Scrypt Coin with Super Blocks

[Hippie Tech]

I think it did just that or it got 51'd.

The 7 blocks / 450 coins I solo'd this morning are gone and the ledger is blank.

HT xD

Mining solo - all ok.

Mining solo - all ok.

Pls, show your conf file.

Not sure if I've been mining on the main chain. Anyone have good nodes to add?

You can add it as a node also:

addnode=50.116.22.43

Could you give me link to actual client binnaries?
QT from first page gives me information about upgrade to Litecoin 0.6.9.1 and I cannot sync with JKC network.

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:

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://bitcointalk.org/index.php?topic=202454.msg2362053#msg2362053 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.

I thought it might have been talked about before, yup.  But I couldn't find the list.   So I made a new one

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.

I´m the only one with the coin?

Since yesterday, 4 more blocks

http://coin-base.net/jkccoin/
1% POOL FEE
Payoutsystem prop
only 90 confirms

[vata2013]

what about new version?

"We are currently not accepting new user registrations."?!?!?

[ortchi]

After all the blocks were orphaned, I have the pool closed. The last two blocks arrived me. Now the pool is open again.

[Hippie Tech]

The client will not connect. Did I miss some addnodes ?

[ortchi]

I use addnode=72.14.178.111 addnode=50.116.22.43 and get 2 connect.

[Hippie Tech]

I use addnode=72.14.178.111 addnode=50.116.22.43 and get 2 connect.

Thx ! That worked.

They should be posted in the OP.

HI HO Junk Miners

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

LOL
