so an idea about physical payment token arised on irc,

main points
* keypad for pc independent pin code entry
* cheap 7seg screen for payment sum confirming
* prom for program memory(possibly a protected ucontroller) to guarantee uninfected device side software
* eeprom for wallet.dat(encrypted with decryption key only on prom with read disable keys switched on prom)
* some communications with pc to get payment data for user to confirm and to sysnc wallets

benifits
* protection against infected pc, private keys never leave the device
* over the counter payment

pitfalls
* even protected ucontrollers are suspectible to power use analyzis, and other grazy hackery eg like this http://www.bit-tech.net/news/bits/2010/02/10/tpm-security-cracked-wide-open/1
* nothing protects against http://xkcd.com/538/

exchange rate hovers around 17$ for one btc at the moment

sry i have trouble actually beliving this, you just lost 500k$ and you have a problem with turning off your work pc? seriously?
personally i think this is a troll, but if not, then you did everything in your power to lose that money, short of posting your wallet.dat on forum for "safekeeping" and it most deffinetly was not a hack from far away, physical attack vectors are always 100X easier

if you dont know how to protect your assets they will find a new owner, that applies in both bitcoin and offline, someone having 500k$ under their bed and telling their friends about it will lose it very quickly too

now if only we could patch bitcoin client to include loic for attacking "enemies of bitcoin"...

FTFY

hey we can stick this one up anyones nose who tries to claim bitcoin is a ponzi scheme, and say here atleast this lobby group takes us seriously althou they dont like us

celebrations are in order, states have to recognise you first before they can fight you

all bitcoin transactions are recorded in the blockchain, if you sent it on its way then it irrelevant if their client died or not
look your transaction up on http://blockexplorer.com/

eligius us pool is down, eu pool is still up tho

naah it really looks like some script kiddie is pissed off, even gribble(irc bot) died for a while tho i dont know if it were from natural causes or was it  a murder
can you link the threats on the forum?

okey looks like i'll be taking the osCommerce module, it will most likely be modified out of Zen Cart module, i might get some help from osCommerce community

would anyone be willing to try to get excisting modules(list in the first post) included with the default releases of the webshops,
vendors are far more likely to take bitcoin into use if they dont have to find and get the modules from third party but can just enable it from the webshop config

mkay osCommerce would take the payment module into use if its provided to them, does any of the webshops accepting bitcoin already use osCommerce with their own implementation of bitcoin payment module? would hate to reinvent the wheel

The expected generation output, at 750 Khps, given current difficulty of 434882.7217497 , is 0.00173465453491 BTC per day and 7.2277272288e-05 BTC per hour.

if you are heating your living room with it i guess its as good as using any electric radiator(makes more noise tho), but for the mining output? totally worthless

well lets see what osCommerce community thinks of it

use of "we should" was not falling victim to the bystander syndrome, it was pretty intentional, you see i really really dislike web development as such

if however someone already had a working php module for shopping cart systems(and obviously many people do) i wouldnt mind walking through development irc channels trying to convince someone to include that feature in their software releases

here is a list of open source webshops

and here is a list of open source webshops supporting bitcoin(bitcoin modules available but not included in the official release)

Virtumart
Zen Cart
OpenCart
WP e-commerce

now its obvious that the true value of a currency is what you can buy for it, so to raise bitcoin value we must get more vendors to accept bitcoin
but that can never happen until webshop softwares start supporting bitcoin payments

now most of these software solutions are written in php, two in java and two in python, one of perl and one of asp .NET
so what we need first is a php webshop module to attach to half of these solutions

now i looked around a list of businesses accepting bitcoin and found few vendors use some of these widely used eCommerce softwares,
eg My Healthy Organics uses zencart a php based foss eCommerce solution
the thing is that Zen Cart featurelist does not include bitcoin payments as far as i can tell, so did the vendor write his own support for the feature?

i think we could get lot more vendors supporting bitcoin if we could get a "pay with bitcoin" feature from some of these sites on the list and get the feature included in all the most used foss webshop solutions

so is there any vendor here who has modified their webshop software and could we approach the webshop development teams with that solution?

heres a waffer pool, they gather lots of designs from all around and put them all on one wafer, it makes developing your chip a lot more affordable, to know how cheap you need to know how large your chip is going to be and what technology you plan on using then you can get a quote from them, eventual implementation in asic might be economically feasible in a year or so if the bitcoin economy grows at a current rate and trasaction fees start bringing money in. but first the technology must be optimized and verified on fpga before anyone will even seriously think of paying all that money for trying the design out on a asic

if bitcoin grows eventually asic implementation will be more efficient than using graphics cards and the first one to come up with an asic design for it will make some neat profit. i hope there will be an open source implementation but probably some corporation is going to cut in and steal that low hanging fruit if it becomes profitable enough, right now its far from profitable enough

maybe focus on the price and secondary featureset of the board rather than cabability for fast bitcoin mining, you are not going to get rich quick with that anyway
i bought Basys2 from digilent, should be great starter kit for very good price if you are a univercity student, you might want to take a look around that site, they have lots of Xilinx dev boards, take a look into your wallet and decide what you can afford. most people say its more important to get cracking hands on with the hardware than to spends lots of time selecting THE board, you will probably buy some more capable board later on anyway

i wouldnt reccommend buying fpga board if you only want to mine bitcoins but if you want to learn fpga development i guess you would already know what you want
also pretty decent programming skills and good understanding of electronics are a prequisite

Hi

i have also been wanting to get into fpga development for ages and this bitcoin mining idea made the final push to aquiring an fpga dev board, will get get my basys2 pcb with spartan 3e 250k gate device on thursday.
ofcourse i cant put fully pipelined implementation in it as its about 3X larger than the fpga would fit but i imagine i could fit a looped implementation into it easily

so thanks for releasing the code it will be a good reference

i dont know if i'll get to the actual implementation working on it but among other projects this will certainly be one idea i'll try
