Download of mine pool monitoring on the official website of coin
their service is very good
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
2. Alarm value can be set by sub account or all
3. The notification mode is SMS or email, and the alarm interval is half an hour, one hour and two hours.
you may have to dig for 5 years to get a block. Team mining is that once anyone in the team gets a block, they will divide the currency in the block according to their performance, so that they can get bitcoin quickly.

4. After that, it is an introction to the theoretical basis of the research content
5. The main part of the play is naturally its own research content. It's better for teachers who don't know much about the relevant aspects to have a general idea of what they have done, what the research results are and how the research results are
6. If the above is troublesome, what kind of person is recommended to help you do it on your behalf? I have asked the team of Youyi to help me before, and the effect is OK< Finally, it is a summary and Prospect of the work< Thank you for your guidance and support
download the PPT template of graation thesis defense, and go to weirdo.com
1. General content: subject title, respondent, subject performance time, subject leading teachers, subject return, thanks, etc
2. Research contents: research objectives, planning and design (flow chart), operation process, research results, innovation, utilization value, new ideas on the continuation of the project, etc
3. Ppt should be well illustrated, highlight the key points, let the defense teacher know which is completed independently, not too many pages, about 30 pages is enough, not too many words, the teacher is not very interested in words and formulas
4. All charts and formulas pasted on PPT should be able to justify themselves, and those that are not sure should not be pasted on them
5. Remember to mark the page number at the bottom of each page, which is more convenient for judges and teachers to review when they ask questions
about templates:
1. Don't use too rich enterprise business templates, academic ppt had better be low-key and concise
2. Select three color matching methods: white background (black, red and blue), blue background (white or yellow) and black background (white and yellow), which can ensure the quality of the slide. I personally feel that academic PPT is better than white background
3. You can make your own template to match the theme of the project. It's very simple. You can just insert your favorite pictures in the "slide master" mode
about words:
1. First of all, don't be too many!!! The picture is better than the table, the table is better than the text, and the person who reads according to the PPT is the worst
2. The font size should be ppt by default, 44 or 40 for the title, 32 for the text, and generally no less than 20. The title should be in bold and the text should be in Song typeface. If you must use rare typeface, remember to go to the computer when you reply, otherwise it will not be displayed
3. Generally, the number of words in a line is about 20-25, not more than 6-7 lines. Not more than 10 lines. There should be a certain space between rows and between segments, and the space between headings (segment space) should be greater than the line space
about pictures:
1. Pictures should have the same position in PPT, and there should be no more than three layouts in all ppt. The picture is best in the same pattern. On the one hand, it is very refined. On the other hand, it shows a rigorous attitude towards learning. Sometimes with shadow or frame around the picture, there will be unexpected effect
2. About the pattern, TIF format is mainly used for printing. Its high quality can not be reflected in PPT. Just choose JPG for photos. I recommend BMP format for schematic diagram. Draw directly in the windows brush according to the required size, without zooming. What comes out is vector effect. Compared with Pro, the relevant arrow elements can come directly from word
3. The flow chart can be drawn with VISO, which is well known by people on the earth
4. The best way to present pictures in PPT is to be concise to less than two, or that sentence, low-key and simple;
