Unfortunately the time has come to close the doors on my LKY pool @ http://lky.scryptmining.com

While its one of only 3 pools (and the only non-p2pool) still alive since launch, the pool has seen little hashrate for quite some time, and no miners or blocks for more than 48hrs now. I wish LKY success, and will gladly re-open my doors in support of the coin should the need arise, but at this point there is little reason to leave an empty pool running.

The website will remain up for at least 7 days for anyone to withdraw coins that needs to, though mining will be shut off as of now. Any payments triggered from the site get sent out in 15 minute intervals after this point.

Good luck to the coin, and thanks to the miners who supported the pool!

Thanks for supporting the LKY network over the last months!

Hey please fix that blockchain sync problem.
Nibble Coin fixed it with a new conf file.

otherwise the LKY will be dead very fast.

Thanks for pointing this out.
I have already studied your modifications some days ago, they look interesting.

Is your retargeting mechanism susceptible to the following attack scenario, that is currently carried out against TRC?

They should not, they still rely on ArtForz's fix where retarget looks back to the last block in the previous target interval, instead of looking at the first block in the current one.

There's however a flaw in the 4 hour cap (so much for testing...), it will only trigger if a block takes more than four hours to find, instead of triggering when a retarget takes more than 4 hours to occur.

A fix will be pushed soon, I'll let you know when it's available so you can look at it.

Titan, if you want to PM me we can have a discussion about LKY's future on Multipool, however please understand that my position is that once a coin is public, and on exchanges, anyone should be free to mine it, including those who only want to mine when it is profitable to do so.

Even though I don't like the concept of multipools, I have to admit that is correct. If you go public, you go public. Only reasonnable thing to do is to adjust difficulty algorithms and code so that this practice is no longer profitable.

One thing we did to help Noirbits (which I develop) is to place a max. time before next retarget. Basically, if difficulty gets too high for the actual hashrate, and next retarget takes too long to kick in, it is automatically dropped (for Noirbits, 4 hours max., while retargets are supposed to occur every hour).

The next step we are taking is too force a difficulty increase when blocks go too fast, so that we have symmetrical difficulty adjustements.

Just my two coins, but it might give you some ideas to improve your difficulty retarget rules...

Thank you all for your input!

I find it interesting to see this strong vote for an open network and the 'let it fight for survival' attitude.

But I think hardly any project would succeed if there is no oversight and guidance or the results would be well below the potential.

www.multipool.us

I'm not keen to get in another public argument in this thread, however, I will state for the record that the manner in which the question was brought to me in my pool thread and then in the ARG thread had as much to do with the answer ARG got as my own personal rationale for keeping ARG on Multipool.

I will not reply in this thread again regarding this topic.

Spawning a new coin when the community is already unable to secure the coins it already has seems closer to the "root cause" of the "problem"...

All cryptos are FIAT digital currency. Do not use.

Dear Luckycoin Community,

One way to cure the current difficulty fluctuations on the Luckycoin network is to go to the root cause and ask for a suspension or removal of LKY from multipool.in.
My investigations have shown that essentially all the 400MH/s we see after a retarget come from the multipool site.
This measure would give back the real supporters of the Luckycoin network the opportunity to mine their fair share of coins.

Please post your opinion regarding this measure.

Titan

I would make the difficulty 100 times what it would be, if/when the network's hashrate jumps by a factor of x. If we can't have them, then no one will ! Grin

A less drastic measure would be to make the diff retarget, time based and/or sensitive to the total network hashpower in real time.

Both ideas will immediately cut off the parasite's supply of easy blocks.

Best of luck, but they've more or less rejected this concept (see the old Argentum thread for some details). In short, they don't care about 'real supporters' (we are suckers), and they'll do whatever they can if it makes a quick buck.

i disagree, this measure doesnt actually supports the open digital currency idea. Maybe something like stbgefltc/barwizi did to Noirbits will be more helpfull.

Titan, how is the difficulty fix coming?

I have analyzed the Mincoin algorithm. It went form a 4x/4x to a 2x/8x configuration.
So the difficulty cannot rise as fast as before (2x) and it drops more quickly (8x).
This makes sense in some situations and we can also go into that direction.

I am still researching the other parameters. We certainly want to avoid a situation like Craftcoin.

Titan

You could add some clause like testnet, such as "if no block at all is found in X minutes, difficulty immediately drops to Y".
Has this already been tested in a living coin?

This causes a synchronization issue. Think about a block that is found exactly at the cutoff time. The chain would fork and the question is who has the right chain now.
