    Bitcoin, generate coins in total pool



    Kriptovalyuta Bitcoin continues to evolve, the complexity of the generating unit is increased each time. Trading on the stock exchanges were happening there is a very substantial amount. But generating alone is almost impossible.
    Today we will focus on generating currencies collectively - in the total. In this case, the prize for the generation of energy is shared among all members of the pool is roughly proportional to the contribution to the generation unit.
    Due to the large pool of total units of power generation computing is much more than if you work alone, but less than one award for each participant. In the long-term average is about the same (minus the percentage of the pool owner), but uniformly. What is Bitcoin and how it works for Habré already has articles. And here is the generation of a complete set of information is highly fragmented, even on their own wiki. This article describes the mechanism of swimming pools available, the client programs and some of the results.

    First , some terminology

    Block ( Block ) - a block of Bitcoin exchange transactions , signed cryptographic hash function SHA - 256 .
    signature block does not contain any key generating and testing can be any , but the signature block should be less of a " target " ( considering signature and effect as 256-bit integers ) , roughly speaking - has at the beginning of a series of zero bits . Thus , to generate a correct signature is difficult - you need to take a long block parameters for the hash unit received less objective . example block. Complexity (difficulty ) - the relative complexity of the signature generation unit . Complexity = 1 corresponds to the purpose for which the first 32 bits are zero. Therefore , in order to generate the signature block , on average '2 ^ 32 * Attempts complexity " hashing ( block). The complexity is recalculated every customer Bitcoin about once every 2 weeks , so the rate of generation units of blocks was about 6 hours . The current complexity of about 157,416 ( the first 49 bits of the hash should be zero and then 23 bits of the hash should be less 6A93B3 ) Mining ( Mining) - the process of selection of signature blocks . It is the only source of growth " money supply " Bitcoin and simultaneously serves to keep all transactions . Bowl ( Share) - Candidate signature block - the block and its hash containing the first 32 bits of zeros . As the number of ball pools , consider the contribution of each participant in the signature generation unit . When an equal each ball is signed under the current - . Only every 157,416 -tion , on average , Poole ( pool ) - Mining server distribution - using the computing power of participants . Poole gives participants the current block and waits for the ball . Once a participant sends a ball , which is less than the target current , the pool unit announces the generation of a signature. The prize for the generation unit (currently 50 + BTC voluntary tax on the transaction ) is distributed among the participants , the pool owner has a certain fraction . Allocation rules vary from pool to pool , this will be discussed below . Ball outdated (obsolete Share) - a ball that came the party too late , after the corresponding block has been signed by someone . The client program seeks to find the signature block , or until it receives a retreat . If the pool does not send a client program or course they do not rebound understands that a part of the ball ( as they say , 0.5 % -1.5 % ) will be made ***8203;***8203;obsolete . Support for " Lights Out " in pools implemented via long polling . Miner ( Miner ) - client software for mining. To join the pool requires a client program separately as normal client Bitcoin mining pool there . mining is also referred to as an account for a client program to the pool participant. A participant can create several miners without additional registration to the pool to use multiple client programs ( different types and / or on different computers ) and earn an income from them in a bag . Considerations points-based system ( Score) - evaluation system ball depending on the time of receipt of the pool. PRICE glasses balls increases with time over a single unit of work , or to the most recent balls will pay more . This system was designed to combat fraud - Strategy out of the pool after some time working in the unit . If the spheres are equal , it is advantageous , after disconnecting the total number of balls equal to 0.435 * complexity and navigate to a single generation (or PPS , see below). But this is considered cheating

    Now for pools

    1 )

    most of the pools. The aggregate computing power - 854 Ghash / s ( gigaheshey per second ) . According , the pool generates almost half of the blocks of signatures (see diagram) , which is already starting to worry . There are two models to receive your part: 1 ) proportional (proportional ) . In this case , the participant receives a share proportional to the number of balls detected, and found that all the balls (except aging parts), and not only to the signature block successfully. The shareholding - . 3 % 2 ) Fixing to the ball ( Pay per share , PPS ) . For each participant (not old ) gets the ball 0.00028584821460503 BTC , regardless of the proportion of the signature block , etc. It is not difficult to calculate that this price is almost exactly equal to the balls 50 * 0.9 BTC / complexity. That is, in the medium to long term, the participant will receive 90 % of their share of work in the signature generation . The parcel owner to - . 10 % Model is defined for each account miner - party, so you can use both models at once if you have multiple CPU / GPU . Your participation is available immediately, without waiting for confirmation of the block . Moreover, the part is not displayed, even if the block is invalid ( invalid block if somewhere would be generated during a long chain units does not include this .) 2 ) (also known as mud pool ) on the second set capacity . The total processing power - 312 Ghash / s . Now , this pool generates about one-sixth of the signatures of blocks (though in April had third of the total power ) . pool parties holder - 2 % ( 1 BTC to 50 BTC award ) . Part of the prize will receive only participants who submitted successfully signed balls for the block. Thus , if the block was not signed this pool , all the balls that are sent to the pool in the block are unused . part of the award is in points ( score -based system ) , the real author of the accounting system in points and mud, the pool owner . parts ' s is only possible after the unit - . after 120 units signed after this ( around 20 hours) 3 ) Power - 146 Ghash / s Registration is open . The holder action - 2% . Fraction of the unit receives only those participants who sent the ball into the block . part of the award is in points. Payment for shares is only possible after the block 120 blocks . 4 ) Power - 34.3 Ghash / s shareholder - just volunteers taxes ( 50 percent of BTC did not take) . Fraction of unity for all participants who sent the balls with the signing of a pool of the previous block . parts of the premium is proportional to the number of ball. Payment for shares is only possible after the block 120 blocks . 5 ) Power Eligius - 31.8 Ghash / s pool without the need to register - just enter your Bitcoin address and not translate their part , and immediately - right in the generated block ( using transaction generated ) . shareholder - voluntary taxes more 0.00000001 BTC transactions per second (about 0.0003 % ) . The share of mining - in proportion to the number of ball from the previous block created pool. If the block is invalidated , the number is converted to a ball found the next block . Interestingly , this pool is probably the first to introduce additional rules for operations that includes the pool block - 0.00004096 BTC to 512 byte transactions . 6 ) energy - 1.8 ghâsh / s new additions to the list of pools , positioned as a competitor to the PPS regime deepbit . parts for Mining - fixed for the ball ( Pay per share ) . The present value of 0.00029220039715181 BTC balls , ie , the commission is 8 % . Also promised to pay the cost of once, even the standby power generation unit . ( energy groups and the rules given in writing )


    The client program (miners)

    1) the Ufasoft SSE2 CPU miner - Bitcoin miner

    uses CPU, optimized for SSE. According to the author, a mixture requires about 1000 CPU cycles.
    I get about 1100 cycles - in my Q9550 Kwade mining produces 12.5 Mhash / s, if you give all 4 cores (running in a thread-4) and 9.5 Mhash / s if a 3-core.
    Processor heated to 60 degrees during the loading of four cores, which have some tense (in resting temperature is about 40), but the work is quite possible. When you carry three cores - heating to 53 and you can still watch HD movies. Most of the time the balls are generated in this way.
    For comparison, the official Bitcoin client (bitcoin- Maini at the speed of 4.9 Mash / s, if it is to give all 4 core Q9550. 2) the mining m0mchil python - poclbm uses OpenCL. In CPU I do not want it to work, but the question vidyashka 8600GT 6.8 Mhash / s. Unfortunately, the miner will be released with GPU-core in 95% -99% and vidyashka heated to 75 degrees. And to do anything about computer operation, mining is extremely difficult - even the window is dragged idiots. Game option-f given nothing. perhaps more powerful video card holders will be able to get the results and the highest, and the brakes less. According to the wiki on the ATI Radeon HD 5970 can reach 802 Mhash / s. There are still miners, but I have not tried yet: 3) of jgarzik CPU miner 4) Diablo java GPU / CPU miner
