[ANN] Noirbits Update required Improved algos !!!!

[oatmo]

Are you guys changing the difficulty retarget?.. because if so you need to be very vocal to all interested parties. HYC died shortly after that and ELC is struggling to survive. There has to be over a hundered Noirbits clients in the wild that will all need to update too.

we havent finalized everything yet, we are hoping to announce an update soon and have it effective in two days, first we have to agree here.

So I think the proposed change is that we go from 2 hour retargets to 1 (every 30 blocks), with a max of 4 hours (with a block, if it's been more than 4 hours since a retarget, then a retarget occurs with that block). This seems good to me, and I think will clean up the current problem with a ton of added hash, then having it removed.

Two days might be a bit short notice...

Noirbits Bank of Nigeria.

I have 1 million Noirbits owed to me after the passing of a dear friend. I would like from you some help. please can you pay me $100 only, so that I can release the funds and pay you %25. Please, thank you, your dear friend.

Should we have a vote on whether to take Noirbits off of coinchoose until the adjustments are made? It can be taken off if a dev contacts sal002

[Jazkal]

I vote leave it on CoinChoose.

Weakness has been identified, and is being addressed. The value of Noirbits coincides with the introduction to CoinChoose, leave it on there. It introduces it to the masses, and once they research it, they will see the benefits of having a real devteam behind the Coin.

Once the patch comes out, it will be OK.

Finally ! Retarget should be next on next block... unless I miscalculated

[barwizi]

ah!!!! you wernt' supposed to tell!!!! 

[philipkdick]

can't wait to help promo it for you !

I vote to leave it on.

barwheezy, i have just invested in your Noribits on nanotokens. if you are succesful in lowering the blocktime, please offer me an insight on how it is done. i'm afraid i might kill my coin

retarget is the issue, blocktime is fine

oh, i see. seems to be a combination of the issue for me. retarget is only happening every 48 hours which makes  for some sluggish spells. anywho, sorry for the thread jack brother. i'll hit you up sometime.

Nope. Currently, retarget is set every 60 blocks, which is about 2hours at regular block time (~2min.). Last retarget was too long due to a spike in hashrate, pushing a high target on the network, which then caused a massive drop in hashrate. Block time for the network increased to about 20~30mn instead of 2.

For those worried about their coins, changing retarget rules will not kill your coins. It will only change the way difficulty is adjusted at retargets, and prevent issues like we've seen yesterday.

Couldn't you chose a better name for a coin?

are you complaining on every coins name? wtf?

thanks for the heads up man. oddly, the same thing happened to my coin yesterday after launch. hashrate shot through the roof and now the diff seems to be stuck really high. been at .8 for almost 24 hours

[jdebunt]

gave this coin a try yesterday, it's fun to mine, pool gave me pretty much 0.1% stales which is awesome

Might turn back to this later today

Something is wrong with Coinmine again.. It won't recognise any of my new workers. They connect fine, show that they are getting accepted shares, but the web interface doesn't show them as connected. Gonna connect my new workers to miners-united and go to bed.

bug in cronjob - fixed now. Mining was not interrupted

Well, here's a new idea for diff adjustments :

* Hourly retargets (every 30 blocks @ ~2min block time)
* Retarget on next block if no retarget for 4 hours. Ensures that difficulty will drop back after hashrate spikes.
* Retarget limits :
** Caps on increases to avoid massive difficulty spikes. If increased hashrate is sustained, the difficulty will follow up pretty quickly in a couple of retargets.
** Uncapped difficulty decreases : ensures miners who decide to support the coin despite high difficulty and lower income get rewarded. It is complementary of the 4 hours rule, for the cases where difficulty has increased over a while (a few days), but lower profitability will cause massive hashrate drops (TY CoinChoose...). Even with the 4 hour rule, difficulty would take a while to recover from the sustained difficulty increase.

The idea here is to give smooth adjustments that really correlate to the network's hashrate.

What do you guys think ?
