How long would it take the super-ist super-computer to generate & save 1/10 of all possible addresses? .0686 btc bounty!

I'll give it a shot, someone please correct me if I'm wrong.

Let's say we generate 10 trillion addresses per second, which corresponds to a few times more than 100,000 high-end ATI cards.

2^160 / 10 / 10^13 / 60 / 60 / 24 / 365 / 1000, or ~ 4.63x1023 is the number of millennia it would take to generate nearly 1/10 of all possible addresses. "Nearly", because we disregarded collisions.

There are almost 2256 (2256-232-29-28-27-26-24-1) valid private keys. Two private keys can correspond to the same address. So actually it would take ~ 3.67x1052 millennia to be absolutely sure you've generated 1/10 of all possible addresses.

If it's possible to check whether you have generated an address before, with zero cost, then you will know that you have generated 1/10 of all possible addresses some time between 4.63x1023 and 3.67x1052 millenia. By comparison, the universe existed for about 1.4x107 millennia.
Additional .6174BTC bounty for percent chance of that super-ist super-computer creating an address which collides with any already-existing address within 20 years.
+.314BTC bounty to give percent chance of successfully brute-forcing this password ("ingk32%(#ldNUI93") on a WinZip archive with AES-128 encryption within 1 minute using 100k of those same ATI cards, assuming they are each able to push out 4million valid passwords per second.

ETA: Feel free to round to the nearest billionth. Tongue

It is getting off-topic though, why don't you create a new thread to resume this? Large numbers kinda turn me on I guess... Tongue

Heh. Forgot what this thread was even about. I'll quit bumping.
4902  Other / Beginners & Help / Re: Power Pricing - What is your Cost per kWh ? on: February 04, 2012, 08:25:00 PM
My price is an average, as since i have a Smart Meter and my power company charges me different rates at different parts of the day.

They break up the day into 3 sections:
50% (12 of 24 Hours) Off Peak Times - 6.2 cents/kWh
25% (6 of 24 hours) Mid Peak Times - 9.2 cents/kWh
25% (6 of 24 Hours) On Peak Times - 10.8 cents/kWh

But if i were running 24/7 the average would be 7.74 cents/kWh.

Thanks for the input Smiley
That's nice. You could over-volt your cards at night, under-volt during the day. I imagine off-peak hours are during night, too, so lower ambient temperatures (assuming you leave your windows open) were you to over-volt during those times. Gotta call the electricity provider where I'm moving... They usually only supply oil but have a lot of wells there, so decided to provide the electricity for the entire area where they have oil wells... maybe they'd be open to something like that.

Email from 27m ago in case you didn't get it:

Please be patient, payouts will be on time and with the correct PPS values depending on difficulty shares were earned at. This is what we are fixing up right now.

4904  Bitcoin / Bitcoin Discussion / Re: Why some pools pay 115% that much? on: February 04, 2012, 07:13:34 PM
Two legit reasons have been given -- can't say pools do either or these (and these are just the ones I've heard of).

1) Pool op sells mining contracts. Pool op sells hashing power @ >115% value, collects arbitrage profit, lures miners with better rates.
2) Pool op is unable to purchase Bitcoins using his native currency, but either wants BTC, or has people lining up to buy the BTC. Because others are also unable to buy BTC in their native currency, they pay a significant (>115% market value) premium.

It’s not how the pools are making money.  Item 1 just describes EBay. That’s not the problem. Who’s buying it is and for what purpose. For item 2 wouldn’t it be cheaper and quicker to buy USD then exchange it directly for BTC? Or better still, the shill could just buy BTC and sell it to the marks.
(@P4 - edited original reply to clarify what I meant by #1) -- GPUMax is a good example of miners leasing hashing power, and an operator (who brings the leasers and leasees together) collecting arbitrage. https://bitcointalk.org/index.php?topic=55819.0;topicseen

Dunno if SA guy is fraudulent or not -- didn't read it well. Read Paypal doesn't deal in SA's ZAR currency, but IIRC from someone else, all major banks hold USD reserves. Maybe it'd cost quite a bit to do a transfer. Idunno. *shrug* Sounds potentially reasonable to me.

Isn't 0.25% is the minimum fee?
Yes.

Two legit (see below -- misspoke) reasons have been given -- can't say pools do either of these (and these are just the ones I've heard of).

ETA: @ #1, mining contracts are sold over price they'd normally earn. Very similar to GLBSE mining ops. Would be cheaper for leasee to do the mining himself, but with an up-front cost of whatever the leasee would like to pay for IPO shares. Mining op owner/operator buys the equipment, does the mining himself, then distributes profits AFTER taking a percent for himself. GLBSE ops have the added benefit (for the leasee) of the "mining contract" lasting "forever."

Last day for higher CD rates. Quick reminder that CDs are personally backed by me -- even if all my loans go bad, you will still get paid.

BDK is now significantly more diversified, and a new "equity diversification" requirement has been added. I am ("BDK" is) now invested in FPGA.contract, imsaguy's lending program, and a meager 5BTC in Bitscalper out of curiosity. "Loan diversification" requirement has also been modified to be more sensible, taking into account all securities instead of just other loans.

ETA: I'm taking a break for at least a couple days. PM me if you want to talk to me. Probably faster to email me if you know the address.
4912  Bitcoin / Mining support / Possible to force Windows to use integrated graphics for display? on: February 04, 2012, 03:45:12 PM
(apologies if wrong forum -- descriptions are pretty vague)

No point using potential hash power of a mining card when there're integrated graphics. Is it possible to force Windows (or through BIOS?) to display on a monitor using only the integrated graphics so the dedicated graphics cards can... you know.... dedicate themselves to mining?

Would this be theoretically possible if an easy-to-implement solution doesn't already exist?


Cheers.
4913  Other / Beginners & Help / Re: Underclocking memory causing crash? on: February 04, 2012, 03:36:18 PM
It can, yes. Usually, the screen will show a bunch of garbage, then crash - if it's set too low. Generally, once you go below 325MHz on modern cards, you're in a territory where the card may crash. It's possible MSI AB was displaying the DDR memory speed, which is probably 2x or more greater than the speed most commonly used to report GPU mem speed. (so, it's possible that Trixx reported it in the common way, which could be 700MHz if displaying mem speed in "DDR" speed, which it's possible MSI AB is doing)

Try 650MHz. Fwiw, I don't believe you can cause any permanent damage by underclocking or overclocking mem speeds -- only problem comes from overvolting & high temps.

Why are you still here?
To encourage people to sell cheaper so he can buy 'em up.  Tongue

This will never happen.


Excellent... ummm... how does that work then?

It's a probability thing.  THe probability of it happening is so low as to be negligible.

Even if you could generate a trillion addresses every second for the rest of your life, generating someone else's address is still less probable than the chance that Barack Obama will pick you up as a hitchhiker, take you to a gas station, where you'll buy the winning lottery ticket for Mega Millions at 12:12pm on 12/12/12 with a ten-dollar bill that fell out of an overhead helicopter into your shirt pocket while the Pope is simultaneously being struck by lightning.
