how to mine a mine pool
the location of a mine pool is also very particular. It's not that a mine pool can be built anywhere, but it needs early-stage capital investment. A mine pool is to combine a single mining machine together. Because of the collection of many miners' computing power, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher. The mine pool will distribute rewards according to the contribution value of each equipment
there are many mines all over the world, and the scale of each mine varies from big to small. Generally, small mines no longer have great advantages. Large mines have many miners for mining. For each miner, he can join any mine or join multiple mines at the same time, The first task of the mine pool is to distribute the income to the miners
(1) PPLNs method
this method gathers the shares g by all miners together. Whenever a certain amount of shares is accumulated (generally 30 million shares), the mine pool will allocate the profits of the previous stage to the miners according to the proportion of contribution
in this way, the income of miners depends entirely on the time needed to dig 30 million shares in the mine pool. If you are lucky, you can dig them in a short time, then the income of miners will be more, otherwise it will be less. In return, the pool charges a 3% tax
(2) PPS mode
for users, the income of this mode is relatively stable
the profit mainly depends on the miner's mining speed. As long as the mining speed is stable, the corresponding profit can be obtained, and the profit is real-time, that is, the mine pool will pay the profit for the miner while the miner is running
obviously, every time a block is calculated, the mine pool has paid for all the miners. If the block fails in the subsequent confirmation link, all the losses will be paid by the pool operator. Therefore, this method reces the risk of the miners, but transfers the risk to the pool operator
therefore, usually the ore pool can charge a handling fee to make up for the possible losses caused by these risks. In this mode, the tax of the ore pool is 7.5%
the above is about how to mine. The difficulty of mining has greatly increased, but the mining army is expanding. If the basic equipment does not meet the standard, it will be difficult to gain in the mining instry, because the value of the virtual currency may not be equal to the price of an equipment, and many miners are not just digging bitcoin, Instead, we choose other virtual currencies to mine.

what is pre-sale
there are many titles for pre-sale personnel, such as pre-sale engineer, solution expert, pre-sale consulting engineer, technical consultant, pre-sale technical support engineer, etc
in fact, pre-sale is a broad term for participants in the pre-sale stage
what is the pre-sales stage the life cycle of an IT project can be roughly divided into three stages: pre-sale, in sale and after-sale pre sale refers to the stage before signing a contract with a customer. It generally includes the process of obtaining clues, customer communication, providing technical solutions, bidding, signing contracts and so on in sale refers to the stage after signing with customers. It includes requirements review, design, development and implementation after sales refers to the stage after project delivery. It includes maintenance, training and technical support presales mainly provide technical support in the pre-sale stage, but continuity is usually considered in an IT project, so presales will also participate in the in-sale and after-sale work the relationship between pre-sales and other IT personnel pre sales vs sales sales (account Manager) undertakes business for the company, and needs to be engaged in business activities such as seeking clues, visiting customers and maintaining customer information but in the process of signing a project, it needs a lot of technical and documentation work. Such as technical communication with customers, writing technical documents and so on. These jobs are usually done by presales
pre sales vs R & d
why not let R & D support sales? Because although R & D understands technology, it doesn't understand business
take software developers for example, they may understand java language, C language, Oracle database and Hadoop architecture, but they may not understand customers' business, such as financial business, medical business, even monetary theory and medical technology. These are business. Technology should be based on business
pre sales is the group of people who know the most about customer business in IT companies. Before sales, the customer's business needs into technical personnel can understand the language
pre sales vs Proct Manager
it sounds like the concept of proct manager in pre-sales and Internet companies is very similar. In fact, in IT companies, there is also the role of proct manager. What's the difference between pre-sale and proct manager
the common point is that both of them need to communicate with customers, research needs and write requirements documents
the difference is: the mission of pre-sales is to sign orders, and the mission of proct manager is to build procts. Before sales, I think more about how to develop the market and sign more projects. The ideal of proct management is how to create better and more marketable procts
type of pre-sale
it is necessary to know the type of pre-sale before answering what to do. According to whether there is a proct, whether it belongs to the headquarters or the region, presale can be divided into four categories
Proct Type pre sales & amp; Scheme type pre-sales
Proct Type pre-sales is the most easy to understand, that is, after the company has a proct, it helps sales to promote the proct to customers. Hardware companies, such as server and switch manufacturers, are mainly pre-sale procts
many enterprise customers want procts that are not available in the market. What manufacturers have to do is to provide solutions. This kind of pre-sale is the solution type pre-sale. For example, in the integrated manufacturers, it is mainly the solution type pre-sale
proct line pre sales & amp; Regional pre-sales
many large IT manufacturers have multiple R & D proct lines, and at the same time, there are many regional centers all over the country. So there are proct line pre-sale and regional pre-sale classification
before sales, proct lines usually focus on a certain instry or even a certain type of business, have forward-looking consideration and layout of procts, and face the national market
Regional pre-sales is closer to customers and better understand their needs. Regional pre-sale needs to face multiple customers or even multiple instries in the region, and the depth of understanding of business is not as deep as that of proct line pre-sale, but the breadth is greater than that of the latter
in this kind of company, proct type pre-sales and regional pre-sales often need to learn from each other and make up for each other
pre sales responsibilities
the basic responsibility of pre-sales is to assist the sales to complete the project signing, and the pre-sales work is mainly carried out around the project life cycle
pre sales stage
< UL >solution planning: pre sales needs to explore instry demands, problems and pain points, sort out instry solutions and best practices, and carry out solution planning and design
Technical Exchange: assist the sales department in technical exchange with the target customers, explain the existing solutions and cases of the company, and understand the needs of customers in the exchange
write solutions: write solutions based on customer needs
scheme explanation: responsible for explaining and demonstrating the scheme for customers, and guiding users to identify with the technical scheme
write technical documents: if the scheme is accepted by users, there are many links to provide technical documents before bidding, such as technical specifications, feasibility study materials, workload evaluation materials, etc
Bidding Support: responsible for assisting sales to complete the bidding work, mainly responsible for the preparation of technical volume and business volume, and going to the bidding site for bid presentation and defense
demand research in the sale stage: after signing the project (often before signing the project), the first step is to conct demand research and analysis, and prepare the top-level design, demand specification, and demand management
requirement disclosure: responsible for the requirement disclosure of the project from pre-sale to in-sale, assist the delivery team to confirm the requirements, and provide relevant documents and knowledge transfer for project implementation
cooperative delivery: cooperate with the delivery manager to complete the delivery of the overall project; Because the company is good at writing materials before sales, it often helps the deliverer manager or customer to write work reports, work summaries, technical innovation and other materials
after sales stage
after sales service: such as proct technical training, material support work
demand collection: in the after-sales stage (often on sale), it is necessary to collect users' new demands before sales. When there are more demands, it is necessary to strive to promote customers to set up another phase of the project
for large IT companies, these responsibilities are usually distributed to different categories of presales, such as solution experts, presales leaders, proct line presales and regional presales
pre sales capability system
(this section will not elaborate, and interested readers can pay attention to other articles of "it pre sales circle")
word: only the pre-sale writers can understand the profundity of word
Excel: mainly used for managing clues and requirements; Before sale, this software is overqualified
ppt: the higher the rank is, the better the PPT is
Visio: used to draw flow chart and network architecture diagram
PS: it will be used when it's cold, I won't elaborate here
mind mapping software, such as mindmaster: help to sort out work, materials and ideas
Axure: it is mainly used for software pre-sale, for interface design
notes: for example, Daoyun notes, OneNote, etc., which are used to record events, take learning notes, and collect materials
