Now some in that community are taking the expensive step of creating custom silicon chips dedicated to running the software that carries out that process.

These chips will be resold to Bitcoin enthusiasts in a line of products that plug into a computer via USB and supercharge its efforts to mine the currency. Butterfly has competition from several other companies working on application-specific integrated circuits, or Mining software bitcoin gold industry term for such specialized chips. The stiffest competition seems likely to come from another U. All three promise to send out products based on their custom chips early next year.

Having an ASIC fabricated is a highly technical and expensive proposition, typically beginning at the low hundreds of thousands of dollars.

ASICs are etched from blocks of silicon with microscopic precision. Butterfly Labs says it has paid for chips with features as small as 65 nanometers; BTCFPGA and some others say they have opted for a cheaper nanometer production process.

Butterfly Labs occupies a large facility in Overland Park, Kansas, where it has bought equipment to manufacture products based on its chip, says Zerlan. That includes a pick-and-place machine to solder mining software bitcoin gold 7. That process is also a competition, with the miner whose software completes the next section of the log—known as a block—being rewarded mining software bitcoin gold newly minted bitcoins. Completing a block requires solving a cryptographic puzzle through brute force, so the faster the software can run, the more likely the miner is to win rewards.

That schedule is enforced by making the work of mining bitcoins harder and periodically halving the reward for completing a new block. Initially relying on high-powered processors, they soon began making use of GPUs, speedy graphics processors that are also popular with the builders of supercomputers.

Small businesses popped up to sell mining rigs and the latest GPUs to other miners. This spring, that arms race took a more serious turn when Butterfly Labs and some other suppliers moved on to FPGAs, chips with a reconfigurable design. Programming FPGAs to perform mining calculations resulted in significant speed increases. Sethumadhavan notes that mining software bitcoin gold profitability mining software bitcoin gold mining is also determined by Bitcoin exchange rates, electricity costs, and the up-front cost of hardware.

However, using ballpark figures makes it mining software bitcoin gold to illustrate how much more a miner could make using an ASIC. When ASICs do arrive, they could force many bitcoin miners to give up. Many small-time mining software bitcoin gold will find that their outmoded equipment will no longer be able to pay for its own electricity bills.

He believes that will help strengthen the Bitcoin economy and enable it to be taken more seriously. But none of that can happen until Zerlan and his competitors deliver their chips. All the most credible-looking ASIC projects have experienced delays and retreated from initial promises that their products would ship in lateciting technical difficulties. If the mining software bitcoin gold do make it to customers, the competitors may find themselves caught up in a race to mining software bitcoin gold newer, faster versions.

These chips, expected next year, will probably be designed to a standard higher than the miners can reach and mining software bitcoin gold be used to build powerful mining rigs without ASICs. Meanwhile, the Bitcoin economy is still based more on speculation than on actual business transactions. Blog host Wordpress became the closest thing to a major brand that accepts bitcoins this monthbut although anything from alpaca socks to e-mail hosting can be bought using the currency, most such products are offered by enthusiasts inside the Bitcoin community.

Unlike real gold, the bitcoins pursued by those building ASICs may not always glitter. Catch up with our coverage of the event. Content creation is hugely expensive for video-game makers. A way to automate some of the process would be hugely valuable, and this could be it. Experts suggest that having AI systems try to outwit one another could help a person judge their intentions.
