Does this stratum issue require any action from miners? E.g. do we need to download a new sgminer or change the stratum+tcp address? I'll be gone for 3 weeks and I hope I can just keep my miner running 24/7 as it is.

No intention to crucify anyone here, I just object promoting DDOS as a solution. This is not how things should be done IMO.

This has to be fixed ASAP!

Allready done on https://bitcointalksearch.org/topic/m.5673549

Also, when pool owners or mpos fixs this, i can help them to test fix.

Thanks. Let's hope it is patched fast. Do you want to make a thread in the Alt Currencies subforum to alert all pools? Most people don't check each coin thread in announcement sections.

issue for https://github.com/Crypto-Expert/stratum-mining .

Here is problem: https://github.com/MPOS/php-mpos/issues/1938

This is cool. So to summarize, we actually have two issues?

1) KGW -> Affects all coins with KGW. Fix with DarkGravity/BlackHole.
2) Fake hash exploit on Stratum -> Local fix on stratum pools needed.

Having a pool with 50% is like printing money - I agree it wouldn't make sense to do anything to risk that position. But as someone already said, someone could hack the pool, and investors looking outside will get wary of investing if they see it being so strongly centralized.

remeber this ?

+1, its highly stable, why would miners leave. Also its a good business for you with all the fees. Why do ppl think doublespending once is worth it on a good coin with bright future.

That's cool, but I don't need to crucified for participating in a discussion about alternative ways to control a network . . apart from relying on hopes that everyone is an honest person and just sending them friendly messages will save everything.

I wasn't saying that it should happen . . only that it's effective. There's been multiple times I've seen it used where the pool owner made no effort to circumvent the situation . . and everyone was better off for it.

I'm not trying to say it's even the pool owner's fault for having the largest pool . . because here again I've seen coins where one of the worst to mediocre pools had 50% of the network.

Bottom line: If your pool goes over 50%, you are a threat to the coin.

I don't think people are asking you to close shop, just take some measures to reduce the percentage from 50 down to 30 or 40, like an increased fee as an incentive for some people to switch. It's not like you'll be losing money from that (increase from 1% to 2% = double money, 3% = triple money etc etc). When it's ok again, you reduce the fee.

50% is unfortunately a danger for the network, even if you have the best of intentions. I mean someone can hack your pool and then, through the 50%, do some "weird" things. This should be prevented as a possibility.

My p2p node is running almost idle, lot resources left, ALL miners welcome! ---- See my sig.

We need DRK Poker....  Please....

Guys,

I am here and try to fix the situation by closing new registrations but it just doesnt help a lot. As mentioned above - my pool seems to be just stable and thats why people are mining here - I will not close mining just because I have 50% of network.

Anyway I am working with lottermining pool op to fix the problem with incorrect shares and all users on my pools seems to be valid ones atm.

feeleep

i know what is going on in the pools. If pool owners contact me , i can explain fake hash vulnerability. All stratum pools need to fix this problem.

Yes, He is fair and has a nice pool, that's why there may be other mean to deal with, like increasing fees temporary.

Coinmine is doing a very decent job as a pool and he's simply picking up the people that leave other pools because he's doing a better job. Should he be DDOSed for that? I think he was relatively cooperative, yet when the official pool went down for changes, the hashrate of coinmine exploded again (which is natural as he picked up a few extra gigahashes). Then the official pool didn't recover the hashrate after the server transfer and also had the orphan problem etc etc. So, naturally, people will opt for what works.

A simple email or pm to an understanding pool owner will do the trick in most cases. I think, from what I've read in his public responses, that he understands the issue, but then again what can he do with the network spikes when a large pool goes down and people use him as a failover? Even if he aims for a 30% market, he can still find himself at >50% on a day where 2 other pools are DDOSed, or are down for whatever reason. We simply need more pools that have a decent hashrate to avoid variance penalties and are operated in a smooth way so that people can diversify their hashrate. P2Pools are good as a concept but I'm getting too many issues, rejects etc. The situation is getting better for sure, relative to one month ago, as there are now much more options to choose from. And it'll probably get better with time.

coinmine got over 50% of net hash rate, but not over 50% of coin generated.

1GH guy is on coinmine ? (maybe)
