Development of btccom open source mine pool
1. Machine: two ant double blade mining machines (rated speed: 180gh / s, rated power consumption: about 360W)
2. Network: ordinary family 8m broadband connection
3. Test time: from 11:00 p.m. on January 27 to 7:00 a.m. on January 28, 2014, a total of 8 hours
4 Comparison:
a miner in btcguild (EU stratum. Btcguild com:3333
the average speed of 8 hours is 175.92gh/s, and the profit is 0.01424974
one miner operates in f2pool (stratum)+ tcp://stratum.f2pool.com : 3333)
8 hours average speed 180gh / s, revenue 0.01230566
5 The test results are expected (the theoretical value under the difficulty of the day does not consider other factors):
the profit of an ant double blade miner in btcguild mine is 0.00194408 more than that in f2pool mine in 8 hours, 0.00024301 more per hour, 0.00583224 more in 1 day (24 hours), and 0.1749672 more in each month (30 days)
After the computing power of the whole network has been improved to a certain extent, the probability of getting rewards is too low, so that some geeks on "bitcoin talk" can develop a method that can combine a small amount of computing power and operate jointly, and use this method to build websites
in this mechanism, no matter how much computing power an indivial miner can use, as long as he participates in mining activities by joining the mine pool, no matter whether he has successfully mined effective data blocks, he can get a small amount of bitcoin reward through his contribution to the mine pool, that is to say, many people cooperate in mining, and the bitcoin reward is shared by many people according to their contribution
as of January 2019, the top five bitcoin pools in global computing power are btc.com, pool, antpool, flush pool, and f2pool. At present, about 70% of global computing power is in the hands of Chinese miners
extended data:
handling charge:
bitcoin miners will charge a small amount of fees for most transactions, the main purpose of which is to prevent people from sending a large number of boring small transactions and wasting network resources. At present, most of the handling charges for each transaction are & T 3647; 0.0001/kb (0.0001btc / KB). In fact, after 0.9.0, the default handling charge will be reced to & 3647; 0.00001/KB(0.00001 btc/KB)
because the amount of data occupied by most transactions is less than 1 kilobyte, generally speaking, the amount of data is less than 3647; 0.00001 (0.00001 BTC / KB) is enough. At the same time, in the future, when the bitcoin block rewards are less, the service charge will become the main source of miners' income, and the service charge of bitcoin will be related to the number of bytes occupied by the transaction
at present, the calculation standard of service charge in bitcoin system is not mandatory, so users can not give any service charge when the transaction is in progress
however, most miners usually give priority to the transaction with higher handling charges when building data blocks, so that they can get higher remuneration when mining is successful. Therefore, the transaction without any handling charges may take a long time to be processed and incorporated into the blockchain
in addition, e to the block capacity limit of 1MB and the recent increase in bitcoin transaction volume, the handling charges have increased significantly, and the waiting time for the transaction to be confirmed has also become much longer

1. The outdoor power supply line is long, or the external wire section is small, resulting in large line loss. Once the home equipment with large power consumption is turned on (such as inction cooker, refrigerator, air conditioner, etc.), the line voltage drop is large, and the voltage is unstable. It is recommended to call the 24-hour power supply service hotline 95598, and the staff will follow up for you
2. The indoor wiring is unreasonable, the cross section of the main wire is too small, and when the equipment with large power consumption starts, the voltage drop is large, resulting in the instability of the same circuit voltage. It is suggested that for the equipment with large power consumption, separate circuit and separate wiring should be adopted
I hope our answers can help you.
