121  Economy / Economics / Re: My personal idea of what will make bitcoin grow very fast. on: June 28, 2011, 07:23:56 PM
In a few years I see this being possible but right now the bitcoin client has to download ~300mb of data via a P2P network which is a bit much for your average smartphone. No doubt soon it will be possible.

We could by pass this on the basis of a client that takes a copy of wallet.dat and handles it on the smart phone. Basically my understanding of the client is that you primary update the blockchain to allow transactions to your address be updated along with your balance...but this info in the blockchain anyway, and you could sync your wallet occasionally instead.

Hrrmmm......
[IDEA]
Along with encrypted wallet feature in future client, add a frame work that allows a secure wallet export and sync to mobile device.


Others here have a far better sense of how it all works and if what I'm saying is feasible, but if it is.....then we can post it at github as a suggestion for future clients.

there is at least one major problem with this:
say we would use two dumbphones with bluetooth (or IR, w/e kind of communication that doesnt need internet or SMS)
so both owners would load theyr wallet.dat on theyr phone
person A buys a beer off person B, and transfers X BTC to person B
thats your idea, right?

now, the current system works becouse person A's wallet.dat will update a block, and delivers that info to the network. the network then verifies this new info (did that specific wallet have X BTC from that block?) and then tells person B's client that the transfer is OK

now, with 2 offline dumbphones, person A could upload a modified/old/otherwise tampered wallet.dat and pay person B with BTC that dont exist/are already spent

person B wont know that, untill he syncs the wallet.dat at home, after wich person A is long gone


paying with mobile phones are ofc the future, but we do need everyone to have internet for it, otherwise its just not safe enough

also, the confirmation time needs to go down, becouse if person A had to wait 5 min~5H for his beer, it wouldnt go very smooth

as for the massive block count: we could use cloud computing for that (use the BTC client on your own computer through the internet for example)

127  Bitcoin / Mining support / Re: GUIminer asus HD5770 CUcore is putting out less than supposed? on: June 27, 2011, 09:24:53 AM
thanks! tried them, and with 128, i get 194.7 as my highest result
what does this do exactly?

edit: found another setting: -v -w128 -f0 gives me 198 max
keeps getting better and better Grin
two days ago i thought all i would get was 140Mhash/s  

edit2:
*dances* using the phoenix miner now, and i broke the 200Mhash/s barrier, doing 208.2Mhash/s now wich is pretty damn good imo
using: VECTORS BFI_INT FASTLOOP=false AGGRESSION=12 -k phatk WORKSIZE=128

thanks for pushing me in this direction, 40~50Mhash/s for free thanks to you Grin

130  Bitcoin / Mining support / GUIminer asus HD5770 CUcore is putting out less than supposed? on: June 27, 2011, 04:13:48 AM

131  Economy / Goods / tip for PCI-E extenders on the cheap on: June 26, 2011, 11:41:43 PM
PCI-E x1 to PCI-E x16
and
PCI-E 1x to PCI-E x1

note, im not the seller, i just spotted them and thought more people should know that theyr overpaying for em Wink
only downside is that since theyr located in hongkong and china, the shipping will take some time (~2weeks)

if the ads are gone, click here for the ebay search and looke for em

or search for PCI extender yourself  Roll Eyes

das waar Cheesy
ben van plan te kijken wanneer de prijzen lekker genoeg liggen om ff te cashen wat ik heb geinvesteerd, en daarna gewoon lekker te sparen en eens in de zoveel tijd (denk aan 1jaar oid) extra cashen Cheesy
mss m'n mining zooi wat upgraden (ga nu voor 1x6990, als ik die kaart kan vinden, later dan mss 2 ofzo Tongue)
133  Other / CPU/GPU Bitcoin mining hardware / Re: Mining Rig Suggestions for a straight-up Newb on: June 25, 2011, 02:17:13 AM
Ok,

I just purchased a Radeon HD 6750 but the problem is that I have a 400W power supply, and the card recommends a 450.  Can I use 400W without any problems?  I don't want destroy my hardware but I'd rather not buy an additional piece of hardware if this can work for a while.

I hate to be so cheap but I'd really like to avoid spending another $90 this month if I can get away with it.  Otherwise, I'll keep on waiting...

Thanks guys!  

It'd probably burn out soonish if you're running the card at 100% 24/7.

he forgets to mention that if its not a good PSU, itl take the rest of the hardware (mobo, CPU, GPU, RAM) with it
you can skimp on anything, except PSU imo
134  Other / Beginners & Help / Re: Has the ship sailed on mining profitability? on: June 24, 2011, 11:00:50 PM
i think its far from sailed
already the prices on tradehill are going back up again (17.2 dollar latest as of now) and mt gox opening up in 3 hours, alot of extra trading will start

so im guessing itl rise to 20~25 quite quickly
135  Other / Beginners & Help / Re: How do I know if I find a block mining solo? on: June 24, 2011, 10:52:26 PM
@jasonstx you would need several serious computers to get that much in a day ... wouldn't you ?

not really, just a whole damn lot of luck...
136  Economy / Goods / Re: Radeon 6990 auction up - Ebay on: June 24, 2011, 07:15:39 PM

138  Economy / Marketplace / Re: Earn 131BTC or 1BTC for getting shops/organisations to accept Bitcoin! on: June 24, 2011, 07:05:22 PM
hmm, so i havent had a reply yet from all the companies, is this common?

edit: i've received an e-mail from shopto saying that they might consider it. the e-mail got stuck in my junk box so i didnt see it right away
also, ive sent an inquiry to the game lord of ultima, part of EA, don't think a huge company like that would accept them on a large scale right away, but who knows what happens if a smaller part of them accepts them...
snowball effect ftw

Als de electriciteit kosten meer gaan worden dan dat het overleverd aan EUROS/USD wordt het link.

dan gaan we zien wie er ballen heeft!
ik ben gewoon van plan om te blijven minen als het niet rendabel is met elektriciteit (heb ik het geluk dat ik dat niet betaal)
maar zelfs als ik het wel betaalde zou ik doorgaan, want zodra het niet meer rendabel is voor de meesten, zullen er een hoop afhaken en wachten tot het weer goed zit
in de tussentijd word de difficulty (met wat geluk) wat lager enzo, dus dan kan het júist een stuk beter zijn Cheesy

bovendien ben ik toch niet van plan om die bitcoins die ik mine snel te verkopen, mss wat speculeren en wat extra mining spul ermee kopen Tongue

groeten uit den haag!
140  Other / Beginners & Help / Re: Is it common for the mining pools to get D.O.S. attacks? on: June 24, 2011, 01:51:21 AM
Thats what i thought that its others that dont like the difficulty going up. but am i right if the difficulty goes up so does the value?
I can't imagine any reason why that would be. BitCoins are still created at the same rate.

true, but then theyr generated at others (ie theyr own) pools, so more profit for them
most pools handle a fee of at least 1% or so, so the more people hash with them, the more money they get from it
ofcourse blocking one pool doesnt mean that all the users go to your pool, but at least a portion of it will
