BitShares PTS / Re: Ypool PTS
« on: December 23, 2014, 10:16:27 am »
We (ypool) will continue to support the old PTS as long as people are actively mining and trading it. Additional we are currently considering to lower the amount of confirmations needed to speed up the confirmation time for users. At this point I don't know how far we can reduce the time since it means that we have to pay miners in advance, but something like a 50-70% reduction would be nice.

Regarding the PTS-DPoS snapshot we did for our pool PTS balances: Instructions on how to redeem the stake will be posted within the next few days.

At ypool.net was found block 59437:
http://ptsexplorer.cloudapp.net/block/0000000eefecbab6bc5e488e2cceaae668cc947a8b1fd26a79eb5fec4092e1e2

Rewards 11.29677699 + 49.53591154 total fees.
Looks like ypool doesn't give fee to miners. Please confirm.
I don't really understand how you came to this conclusion? Of course the coinbase transaction will send the full reward to a specific pool-owned address before it is split up.
If you go to the block statistic page on ypool you can see that block #59437 had a value of 60.832 (reward + fee) which was correctly distributed amongst the miners.
You can find further proof here:

BitShares PTS / Re: Why is ypool destroying PTS? (70% mined by ypool)

One thing I have planned however, is to put up an clearly visible warning sign when the pool reaches at least 30-40% of the network. It will link to a page with detailed explanation of 51% attack and what affect it can have on the reputation and price of the coin. Everybody is then free to decide if he will risk it or leave the pool.

Well? It is 4 days later and I just logged in. I see no warning.  You have a news timeline right when you login. How hard would it be to throw a warning on that? Please do not procrastinate.
Did I say I'll do it immediately? No. I'd like to automate the process and make it clearly visible on every page, not put up a one-time-warning that nobody will ever read again when more news come along. The hashrate issue is not new and there is certainly no need to rush now. I'll add it when I find the time, maybe in a week, maybe later.

It's not that easy, really. How do you think it works? You gain access to the pool server in whatever way and then you just press the big red button? We don't even have standard wallets running and there is no source to be modified or anything. All the attacker will see are just some weird applications running with strange debug output, every intruder will be happy if he is even able to steal some coins.. but even that is not as trivial as you might think. Not on ypool at least.

Security through obscurity is no security.
Thanks for pointing that out. I didn't actually mean to say that obfuscating infrastructure is how our security works, I was just referring to the fact that it is unlikely to ever happen that someone explicitly hacks into a pool server only to pull off a 51% attack. It's not impossible, but very unlikely.

And now you say Oh its cool that people just use one pool... This will kill all other pools leaving PTS to 100% to ypool making it the bottleneck of a coin that was supposed to be a share of future Decentralized Autonomous Corporations, promoted by a company that screams Decentralization but actually does not give a fuck about it.
Why should it affect if people go to ypool or not? Unless bytemaster writes it in big red letters all over the place only about 1% of miners will care about the 51% issue.
If you consider it that important you should invest your energy in making people aware of the problem rather than shouting at bytemaster.

I think a potential solution to this would be to release a distributed pool alongside future DACs which have a built-in mechanism to reward extra shares if people choose to use the distributed pool.  i.e. say 2.5% of ALL mined blocks will be included in the reward for the distributed pool but not for any centralized pools; that way, people could start their own pools if they want, but the distributed pool would have be slightly more profitable and would give incentive for people to switch to it.
What stops a normal pool from disguising as the distributed pool to get the extra 2.5%? The main problem with most suggested solutions is that they require a centralized entity that controls what is real and what not.

a responsible pool would close down registrations at a hashrate of >30% of the network rate.

since they dont care for more than 2 months now i guess they are just greedy knocking of fees.

...

This sucks for ypool because it's not ypool's fault that everybody's flocking to it, but I guess it doesn't suck too much because they are raking in the fees.

i disagree, pariah, responsible pools close down registrations at a certain hashrate.
I can understand that people are worried about the 51% attack issue, but as you said it has been this way for months now and nobody cared. We did not attempt an attack and I honestly have to be insane to even try any kind of attack, as it will drive down the price and therefore also kill our earnings. It's like shooting myself in the foot. But yeah, I understand that trust alone is not good enough.

Actually there is a little anecdote about this. When we reached ~50% of the Primecoin network a few months ago I was really worried people would abandon the pool and flood the internet with anti-ypool messages. To counter this I added standalone Solomining support(see commit) to the most used ypool miner and announced it on our chat and in the peercointalk forum. Surprisingly, hardly anyone cared and the hashrate continued to go up. To this day I doubt the network hashrate by the solominer ever exceeded 2%.

I have discussed closing the pool when nearing 50% hashrate with several people already, but it will lock out only new miners. Nearly every Primecoin or Protoshares miner has an account on ypool already. It wouldn't really affect the hashrate. One thing I have planned however, is to put up an clearly visible warning sign when the pool reaches at least 30-40% of the network. It will link to a page with detailed explanation of 51% attack and what affect it can have on the reputation and price of the coin. Everybody is then free to decide if he will risk it or leave the pool.

On the long term I want to release a miner (open source of course) that will also connect to the coin network and retrieve work information from there. This way it is guaranteed that the pool cannot execute a 51% attack since it is based on withholding/manipulating blocks.

do you really believe the fee is only 6%? ;)
who did the math? ;D
Obviously you didn't. You are moderator on this board and it's a shame to see you spreading rumors.

On a side note we lowered the fee to 5% a few days ago. That is still a lot, I know. But the high fee is one of the things that stop the pool from having 100% of the hashrate.. so it's good for the network, don't you agree?

The problem is, there is no punishment to having 100% hashrate - noone will jump the ship, nor the value will fall until they violate the rules and do something stupid like attempting double-spend. That is, until they get hacked, and that will be the real disaster.
It's not that easy, really. How do you think it works? You gain access to the pool server in whatever way and then you just press the big red button? We don't even have standard wallets running and there is no source to be modified or anything. All the attacker will see are just some weird applications running with strange debug output, every intruder will be happy if he is even able to steal some coins.. but even that is not as trivial as you might think. Not on ypool at least.

Did a 51% attack by a large pool ever happen? Not that I remember.. for very good reasons.

Interesting how none of the staff of ypool have posted on this forum or if they have, haven't commented on this thread. Kinda makes me think they don't care for the network, but rather just care for their wallets..
I don't scavenge all forums daily for new posts. I also kind of lost interest to post anything here.. all I get is permanent bashing from the Protoshares staff. I said it once and I will repeat it again, I am happy to cooperate and answer any concerns, but usually all I can find here is ypool-sucks mentality.

BitShares PTS / Re: Anyone else on Ypool experiencing worse mining today?
« on: December 13, 2013, 03:00:20 am »
The network difficulty roughly doubled today, which reduces everyones earnings drastically. Be aware that this has nothing to do with our pool internal share difficulty, it's just a coincidence that it fell closely together.

BitShares PTS / Re: [ANN] ypool.net - Fast PTS pool
« on: November 26, 2013, 03:13:27 pm »
So anyone care to comment on what this is all about?
Sadly many people use our custom miner software for botnets. As they connect to ypool.net some av-companies have started flagging the entire site as potentially dangerous. I guess I have to write an email to the AV companies and explain the situation to them. Until it is resolved, you can safely ignore the warning.

Hello!

My command line miner show 4 found shares, but its only 1 on the page (right top corner shows shares 1.0000) and it seems to be not increasing.
collisions/min: 20.0742 Shares total: 4

What could be the reason?

Thanks!

Update: now its 11 found shares but 0 on web page...
Please read the FAQ on our page. There is one question that explains what share is and how it works.

jh00 what's happening with the pool right now? Miners gets disconnected all the time.
I was fixing a bug on the website for which I had to restart the webserver several times. It has no effect on mining or coin reward, but it will display some workers as offline while it is synchronizing. As long as the miner itself is reporting no (permanent) disconnects everything is good.

Hi there, after a night mining with some cloud servers on ypool, my shares got lost.
I mean, yesterday night i've got 12 shares, this morning 3 shares on the status page of ypool.
Also, my miners tells me they send something like 66 shares, all accepted, but the counter of pending shares on ypool stats never changes...

Where has all my work gone ?
Please reply, I think this pool steals money.
The shares get converted to unconfirmed PTS and later to balance. In essence your shares counter will be zero most of the time since it is reset every time a new round starts which is quite often. If your unconfirmed/balance increases everything is ok.

I set my minimum payout to 1PTS more than an hour ago and still have not received a payment. I know it used to be 3 PTS but per the website that has been lowered to 1....are there any issues with payouts right now?

F.
Many people did the same, it will take a bit until all the payouts are processed.

WTF jh is auch deutscher?! Wir haben definitiv die technische Oberhand xD

Laut http://coinplorer.com/PTS haben aber immer noch fast alle Bläcke nur eine Transaction drin, das kann doch so nicht stimmen...
Nicht ganz, bin aus Österreich. :)

Das noch einige Blöcke nur eine Transaktion haben liegt daran, dass viele Leute auf ypool ihre Miner noch nicht geupdated haben. Da jeder veraltete Miner nun eine Warnmeldung ausgibt gehe ich davon aus das bis in 1-2 Tagen ein großteil umgestellt hat.

Mal abgesehen davon gibt es auch noch andere Pools die nur 1 TX pro Block unterstützen, wobei ich nicht weiß welche Pools das betrifft.

What about 51% attacks? With the 6 month rule the overall hashing power will go down quite a lot compared to now. This makes it a lot easier for a single individual to pull off a successful attack.

It actually makes it harder because they could not finance the attack with the block rewards.   For example, suppose someone wanted to do a 51% attack today.  They could spend 100K / day on Amazon, but wouldn't be able to maintain the attack unless they had access to 100K * 180 days worth of capital.
You assume that the attacker wants to earn money directly via PTS/BitShares. What if botnets from a different altcoin team up to attack your coin in hope that it will make their altcoin look better? There are some people on this planet that control gigantic amounts of resources nearly for free. Check Feathercoin for example, it was attacked multiple times successfully even though at the time it was very popular and there were many legitimate people mining it.

I am not saying that this is very likely to happen, but it is definitively a possibility that has to be considered.

ypool vorerst gelöscht, da sie aktuell nur Blocks mit einer TX zulassen und somit gegen die Blockchain arbeiten.
Das hat sich seit heute geändert. Bitte wieder hinzufügen.

Please help

Where and how do you install and compile the latest miner in linux?

Thanks
