Topic: [4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool - page 156. (Read 4382653 times)

What's going on with the very long block times on Slush's Pool lately? Has mining power been lost so taking longer to find a block or what's going on?

And I have a wish - to mine that last Bitcoin

Speak for yourself, once BTC hits $100,000 I'm ordering that robot replacement body.

I wasn't being mean, I was being truthful. Everything about your post is absolutely wrong. You need to learn how to research on your own and not believe everything some moron on a forum tells you. Bitcoins do not run out. The last partial coin ever to be mined before the network relies totally on transaction fees will be long after all of us alive today are dead.

Lop not u.  That kurtman guy.  People can't just be nice and help. Instead must asume everything and be rude in the meantime.

I guess its hard for some people to understand that sometimes people ask questions whether they know the answer or not.

I appreciate ur description billbags.  Thank you

^ please don't take that as being rude, i didn't mean it to be, I was just sharing info. I'm not one of meanies around here

This is how it was explained to me

Wow.    So because someone asked a question meabs they don't know much.   Sure.. Keep thinking that.
Sorry for asking a question that may interest many ppl forgive me.

Thanks billbags : .  Rather interesting it is.    Interest calculations for this all.     

I'm happy if we can mine for another + years b4 it runs out... Than I'll be turning to alt coins


Thanks for helping and not being rud .  People And ur damn assumptions.         


21or 25m btc seems like so much yet so little.

You obviously know very little about Bitcoin. Let Google be your friend.

Yes, it will be sooner than originally predicted(to reach 21 million). The problem is hashpower gets added after the calculation is made each time at the 2016 block mark. That's why we are ahead of schedule and it takes less than 14 days most of the time to reach 2016 blocks.

Note: It isn't so much that the amount of hashrate added is excessive (although there is a limit to how much the difficulty can increase - 400% every 2016 blocks), it is that the additional hashrate is not all added at the same time. Say for example that when the difficulty changes, exactly 10% additional hashrate is added to the network then at 1008 blocks after the difficulty changes, an additional 10% of hashpower is added to the network (off of the original hashrate) (and no variances in luck and no other changes to mining power) then by 2016 blocks after the previous difficulty change, the difficulty will be 15% higher but the hashrate will be 20% higher.

This is the block chain's control theory feedback loop:

60minhr∗24hrday∗7dayweek 10minblock=2016 in 2weeks

Tcurrent=Tprior∗tprior/2weeks

D=work/2(32)=2(256)/(Tcurrent+1)∗2(32)

hashes/second≈D∗2(32)/600

The current target for the block chain is determined by a calculation, so any two clients looking at the block chain will calculate the same target. This calculation aims to adjust the target such that one block will be mined every 10 minutes, no matter how much total computing power is devoted to mining. The target changes every 2016 blocks based on the timestamps within those blocks. Why 2016? Because Satoshi decided two weeks was a good interval, and at 10 minutes per block, 2016 blocks will be mined every two weeks.

When 2016 blocks take more than two weeks to mine, the target goes up to make mining easier; when they take less than two weeks, the target goes down to make mining harder. In symbols, if Tprior is the previous target and tprior is the time it took to mine 2016 blocks using that target, then the updated target Tcurrent is just.

The target is typically a huge number well in excess of 2(200). Also it goes down as the total hashing power of the miners goes up. Consequently, interested people usually think in terms of the difficulty instead. Definition: The Bitcoin difficulty is the average number of nonces you have to try to find a valid block — aka. the work — divided by 2(32)(roughly 4 billion).

Note that D is just a number for human consumption. It scales in direct proportion to the computational effort required for mining, so twice the difficulty means twice the effort.

If we know the current difficulty D, we can estimate how fast all miners are hashing in aggregate. On average, it takes D∗2(32) hashes to find a nonce that works, and the target is selected to make that take 10 minutes.

Here's a very interesting thought against the depletion of btc.


25 millionbtc exist to be mined if weve mined about 1m and all the companies and/or banks get in on this.   Wont it mean we will run out of btc a lot faster then the predicted 2020-2040(which I believe it may be shorter than that)




Theories??

Quick question where do you guys get S4 in Europe? Besides asicminer-shop.de?
I found this site where its even cheaper in euros " http://buy-antminer.com/ " but I dont know if its legit, any idea?

Found 2 blocks in less than 4 days last week .

Very lucky considering I'm only at 3.4 Th/s

Thanks, I get it now. Just set up like we used to:

1) run slushs stratum proxy on ethier a pc or pi.

2) put the ip of the computer/pi that's running the proxy into your antminer(instead of stratum.Bitcoin.cz:3333)

3) if your mining somewhere other than slush, make a shortcut for proxy, then right click on shortcut and change "target info" to pool of your choice(since proxy comes normally configured for slush's pool)

Slushs stratum proxy download:

https://mining.bitcoin.cz/mining-proxy-howto

If you have 5 miners at the same location and each one connects to the pool - it's 5 connections.
If you proxy them via single link - it's just one connection ... no matter if the miners are stratum or getwork.

I am not common with antminers, but if they allow for other miner(s) to connect to their cgminer as proxy - that's also an option and will discourage setting-up separate proxy.

I'm a little lost with this. The antminers are using cgminer which is built on a stratum proxy. Why or how would you use an extra stratum proxy on the user end. I used to run one(slushs stratum proxy), but that's because my miners were only getwork enabled(no cgminer/bfgminer) so I understand how that works, I guess my main question is why have an extra stratum proxy?

Thanks @KNK, I'll start getting it sorted

The advantage of having dedicated worker per unit is the ability to monitor them more easily, but you can do this even with proxy on your side.
The proxy will reduce your bandwidth usage and will put less load on the server too, so if you can do it - do it.

Hi Guys,

Quick question..

I'm starting to ramp up my mining efforts at the moment.  I currently have 3 x Antminer S3+ units pointed at the pool, and I've ordered an S4 which is due for delivery today.  Is it better to have each unit with it's own worker setup on the pool side, or for me to setup a stratum proxy locally?

Thanks in advance for your help!

There was a 16 second block a couple of weeks back if I remember rightly too...

Slush's block #21870 was solved in 29 seconds (and confirmed, 25 March 2014), we had a 4 sec block which was invalid.

Cheers
