[4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool

[slush]

Thank you for support :-). My motivation is to consolidate the infrastructure, not to rob pool clueless miners...

Jeff Garzik says that using vardiff=32 (variable, self adjusting difficulty) implemented in the pool stops Avalon ASIC from restarting, probably too high network load caused problems.

I'm afraid that we need vardiff, to remain competitive.

[slush]

I'm working on vardiff, it will be available very soon. Of course I'm fully aware that ASICs won't work on dif1 very well.

Having 6 non-stratum blocks in a row is a little unnerving.

Where?

#16446 - #16451

#16446 - #16451

? Only block 222002 (16446) is version 1, the rest are version 2. Why do you think it is version 1?

[slush]

OVH (datacentre where the pool is hosted) has some problems with datacentre connectivity, they're working on it, but pool seems to be unreachable for most of people now :-(.

[slush]

Oh, it seems that connectivity is recovering again. I'm sorry for troubles.

because they all have nonzero NMC reward.

EDIT: oh, I get it, they managed to produce valid NMC blocks, but not BTC blocks.

[slush]

Yes, non-zero NMC balance doesn't mean that the block itself is version 2. It may also indicate that getwork pool produced low-difficulty block in meantime, so it generated namecoins, but not bitcoins.

[slush]

In few hours I'll migrate main database to another machine. Website will be down for approximate 30 minutes. Mining will be affected only for few seconds during application restart.

Thanks for the explanation. Sorry to scare you.

[slush]

Database migration was smooth, website downtime was 20 minutes + few short restarts. Also OVH issues seems to be fixed, I see zero packet loss from many of network locations again.

Slush I love you man

[slush]

I'm migrating pool wallet to another machine and to the fresh wallet file (current wallet.dat is over 40 MB . The old wallet have some unmatured blocks, so I turned off pool payouts and I'm waiting until all block mature. Then I'll check if everything is fine and I'll turn automatic payout processing again. Payouts should be working again in few hours, I'll surely inform you here.

[slush]

Okay, wallet seems to be fine, I just processed all pending payouts manually. Automatic payouts will be enabled in few moments.

you could use this opportunity, to make another cold backup in case of security breach

What happened? Why is winning pool falling?

[slush]

Nothing happen now. Cosurgi just reminds me the issue with Linode year ago, where I lost over 3000 BTC because of Linode's security hole.

Now the pool keeps only minimum funds, currently around 75 BTC. The rest is in cold storage.
