*takes his rabbies shot and offers Plastic.Elastic a hug*

Helping him to steal isnt exactly how you should show your intelligence. If he must ask these questions he sure doesnt know jack and will be caught easily.

Although I have not devoted a whole lot of thought to 'how is this person accessing 2TH worth of computing power', it seems atleast somewhat 'legit'. I would sure hope he is not stealing anything. Some basic things that lead me to believe it are that he will need physical access for any of my suggestions. His concern of limiting the Internet exposure of the machines is more in line with needing to be able to ensure the security of them more so than to 'hide'. I mean, any network admin on the planet would notice the usage...

If he must ask, he may not be ready for such a project but 'being caught' implies doing something wrong to begin with. Otherwise such an ambitous project is good in excercise to learn from if nothing else.

Whether you are just being antagonistic with implying I am being helpful to show my intelligence, I do not know. But my IQ is really quite low as far as I can tell.

And if it is real, then in the grand scheme of things another ~2TH only goes to further strengthen the network as a whole. That being my main motivator beyond just being helpful, if only mildly helpful.

cheers

Your assumption about ensuring the security of the machines is correct.  You could say I'm trying to hide the machines from others who might wish to steal.

And yes, I hope to learn a lot from this whether I succeed or fail.

DeathandTexas and Sadpandatech - I admit I have some research and consulting with others to do to understand the importance of your advice.  I need to construct a working model in my head of exactly what this will entail.  Thanks for the help! Smiley

Plastic.Elastic - What do you do to relax?  Electricity is "free" as defined by my lease.  I don't need your definition.

Is this 2TH/s computing also "free" in... -i dont know- your tuition fee?

Not only you're stupid, you're lack of morals .... a great combo of failure



I never said the 2 TH/s is free.  But it's cheap enough that I could stand to make a few grand every day.  Me gaining access to these 2 TH/s would mean a priori approval by the entity[ies] controlling the 2 TH/s.

And, I believe the two fine gentlemen helping me may have identified some ways that will allow me to have my request approved.

It's called being sociable, forming good relationships, and establishing connections.  Try it sometime.  Like I said, if this eventually works, I will handsomely reward both of them for their help.  No guarantees it will, though.

aye, Poolservj has work caching, etc. Without using it I am guessing. But it appears it can be set to only send new works on block changes. It also forms the getwork request localy, freeing up resource use on the bitcoind itself.

for C it does have idle detection but I believe it is capable of being on or off.

Best way to find out is get a box setup with VM and run bitcoind/PSJ and break out the ol ethereal on it. Slap as many mining instances as you can pointing at it. You can run multiple miners on one GPU for example to help simulate multiple connections. Get a few hours run and observe your packet counts and system loads and multiply it up.

Stop fabricating things when it's obvious that you have absolutely no clue as to what I'm planning.

You should watch your language and your accusations of me 'stealing.'   I don't steal anything.

Thank you both DeathAndTexas and sadpandatech.  If you think of anything more, I really would appreciate it.  On the off chance that what I'm thinking of might actually come to fruition, both of you will be compensated heftily.

Was no-one else curious about how he would have access to 2 TH?

Do you really need to ask?

Look up the fucker's thread history, you will see his thread about "free" electricity

I'm not suprised, he got another "free" computational power some where....

Yeah.  Because, you know, I really want to attempt to squeeze out 2 T/hash using the free electricity I get from renting a room of a house that was built in the 1950's.

Got to 1 T/hash before my clothes started to melt into my skin.
 Shocked

tl;dr solution; set in place 1 computer running a bitcoind daemon in VM. On same computer a server running pool server on a LAN IP that is capable of pointing to daemon on dif IP. The VM will have it's own net access via cell phone usb, etc. So isolated from the hashing network.  Simply point your hashers at the LAN pool. viola, they are isolated from the net and you are left with only a VM bitcoind communicating out.

This is beautiful.   Grin

I quite like the possibility of solving around 30 blocks per day.

A block-chain communal living complex.

All tenants, as well as payments and community building projects, are verified by other tenants within the complex.  Deviants from the system are "forked" and tossed out.  It'd be like a neighborhood watch group acting as the structure for the community itself.

Here's my guess as to why 2012 will have a large impact on humanity:

1)  Astrological changes lead to slight gravitational changes in our solar system.
2)  Our thoughts have mass.
3)  Our thought processes will be significantly affected by this change in gravity.  But, since this change will be distributed to everything contained in our solar system ('system' being the key word), we will be largely unaware of this shift due to relative, observable stability.
4)  Slow revolution of human consciousness begins (though I think it would be more accurate to say this change has already been occurring).

I don't have a great sarcasm detector... are you serious or just trolling? Tongue

It's a serious guess, but of course I'm not saying it's definitive.

Hello Smiley

Looking to sell a GTX550 Ti 1 gb ddr5 video card.  This card is in excellent condition (still has the protective film on it!).  It was used for about 1 week of Bitcoin mining and gaming before I bought a 6970 for mining/gaming.  The card runs beautifully, has barely been used, and is in very close to brand new condition.

Asking for $80 in BTC shipped within the continental USA.  Product will arrive in original box and packaging with installation/driver disc and manual included.  Brand new, these are about $120.  I'm asking for $80 because of it's great condition.  Great card for gaming at its price!  

Will ship internationally, but you must pay shipping charges.

In honor of a new year. Astana. Bring it Smiley You are so full of shit its funny. Happy 2012. Thanks for all the laughs in 2011. Keep up with the threats and more BS. I will gladly point out every fault in your joke post. BTW: How do you start a post with "The truth is" with a alt peronsa you created and caliming you are a legitimite 3rd party? Ill tell you what. You post YOUR btc address. Then I will give our more or your private info when I see the corisponding deposits to blockexlorere. Unless they are part of my conspiracy too.

Honestly, I think the best thing to do when someone is threatening you with a lawsuit is to never talk with him again unless you are absolutely forced to. On the off chance he is serious about this, however unlikely, you wouldn't want an unfortunately-phrased sentence being turned around on you.  Some people's egos will take them way further than you would expect they would go.

My two cents Smiley

I'm sorry but your biased, and you have no right to hold the money or tell anyone to do so. if the money does not get returned to him, today. And I mean all of the $1600,you will get served with liable suits. Infact a few are going to get served anyway I've decided.

What's a liable suit?  Some people can only afford ugly clothing.

Edit:  In short, couldn't you simply have a computer take the hashing algorithm, process it offline, save the results of the work, connect to the network, then dump all the results at once?


Blocks are linked. You need the previous block to calculate the nonce (which includes a hash of the previous block). Thats why you cant mine offline for longer than ~10 minutes. After 10 minutes you are essentially forking.

^^ This answers te orignal question.

May I ask what is your goal? Are you trying to save bandwidth? Looking to 'mask' the reporting daemon? Trying to minimize net exposure?

Well, I may have access to 2 T/hash under certain conditions, and hashing offline may be one of those conditions.

If you can't connect the computing power to the internet (or some other method of updating the miners) it is useless for mining.  

Remember you need to be solving the next block.  Every 10 minutes "somebody' solves a block.   When that happens your data is stale and if you find a block it is useless as you are solving the wrong block.  A farm which could only connect to the internet once every minute would be horrible inefficient (stales) but would work.   On average you would lose 10% of your hashing power because the data has gone stale and you won't know it until the next update.  Still 2TH * 0.9 = 1.8TH effective.

Longer periods of time between updates will quickly make it impossible to work on the same blockchain as everyone else. Your only hope would be to build a longer chain in private and publish it all at once.  The problem is that for any extended period of time the odds you will have a longer chain is negligible.

As an example, say you have 25% of network capacity and decide to mine privately for x blocks and then publish them all at once if it is longer than the main chain.  

If x = 1 (connect to internet and publish block chain after finding one block) then you have a 25% chance of having longest chain.
If x = 2 (publish after finding two back to back blocks) then you have only a 0.25^2 = 6.25% chance.
If x = 3 0.25^3 = 1.56%
..
If x =6 0.25^6 = 0.02% (1 in 4096 chance).  Even 6 blocks is only on average 4 hours for a 2TH subnet.

So connecting to the network once every 6 blocks and checking to see if you are ahead would earn you (6 * 50 ) / 4096 = 0.08 BTC and it would take 4 hours.  Note you wouldn't earn 0.08 BTC each time.   You would earn 300 BTC 1/4096th of the time and 0 BTC 4095/4096th of the time.  On average despite having 2 TH you would only earn about 0.5 BTC per day (roughly the same as a 500 MH rig which is continually updated).

Now hypothetically if you have some constraint that you could RECEIVE data but only TRANSMIT every couple hours you could operate w/ full efficiency.  Variance would be astronomical (magnitudes higher than normal solo mining) but you could
1) send any block chain updates to the farm
2) if farm is more than 1 block behind it abandons the chain
4) if farm is ahead by 1 or more blocks and time greater than transmit threshold it transmits.

Since you are winning or losing multiple blocks per batch you are going to face very high variance but your expected return (EV) will be the same.


Thank you for this!

Noob, hows your basement operation going?


Not bad.  How is it running around the evolutionary cul-de-sac?

And in response to SadPandaTech, minimizing net exposure, yes.

A true dumbass would never know why ppl call them a dumbass. You're a perfect example of that saying.


Well, statistically, you have about a .5% chance of being more intelligent than I according to 'g.' 

Do you know what projection is?

I know this is hard for you or anyone else who has already 'made up their mind about [me]' to understand, but when I first saw this thread I wanted to say "I am so sorry for your loss". Do you know why I didn't? Because I also immediately thought about what a good scam this would be.

It is not an issue of not having a heart, it's an issue of having a loud brain. Turn yours up and I'll turn mine down.
In case you missed it. There is a photo of a smoke damaged computer that suspiciously looks like a bitcoin miner.


I noticed that photo too.  It's the only photo in the entire lot that was convincing to me.  If it weren't for that photo and that photo alone, I'd be inclined to side with Matthew.  I do believe the house belongs to the OP (though, the photo is a long way from 'proof').

Proof of insurance (or lack thereof) is another issue.

In either case, sorry to hear about the house  Sad  I'm glad nobody was hurt.
