Brief description of calculation power
According to the current difficulty calculation, we can dig about 1.012 Laite coins a day. This is the average calculation result in the mine pool. If there is an efficient mine pool or solo, maybe more
litecoin (abbreviated as LTC, currency symbol: 321;) It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world
lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places
design purpose
it is based on bitcoin protocol, but it is different from bitcoin in that even at the present stage, it can efficiently "mine" through consumer hardware. Liteoin provides you with faster transaction confirmation (2.5 minutes on average). It uses hard memory and mining workload proof algorithm based on scrypt (an encryption algorithm). It is oriented to ordinary computer and graphics processor (GPU) used by most people. The litecain network is expected to proce 84 million currency units
one of the design purposes of litecoin is to provide a mining algorithm, which can be run simultaneously on the bitcoin mining machine. With the rise of application specific integrated circuits (ASIC) designed for bitcoin mining, litecoin is also closely following the technological evolution. But before the widespread use of litecoin currency, it is unlikely that there will be an application specific integrated circuit (ASIC) specially designed for litecoin

transactions
a peer-to-peer network similar to bitcoin handles lightcoin transactions, balances, and issues through a script workload proof scheme (when a sufficiently small hash value is found, the, A block will be created, and the lightcoin will be issued. The process of discovering the hash value and creating the block is called "mining"). The issuing rate of Leyte coins is reced by half every four years (every 840000 pieces) according to the proportional sequence, and finally the total number of LTCs is 84 million. Unlike bitcoin, the memory intensive feature of script makes it more suitable for "mining" with graphics processor (GPU). FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are more expensive than sha256 used for bitcoin
currently, lightcoin can exchange legal tender and bitcoin, most of which are through online trading platforms. Revocable transactions (such as credit card transactions) are generally not used to purchase Leyte, because Leyte transactions are irreversible, which brings the risk of refund. As of April 25, 2013, a Leyte is worth about $3.97 or 0.028 bitcoin. This makes Leyte the second largest electronic currency with a market value of about $35 million
client
litecain is a free software project released under MIT / X11 license, which allows you to run, modify and the software according to your own needs. You can also release a modified version of the software if you like
the software is released in a completely transparent form, and users can independently verify the binary version and the corresponding source code
mine pool
the lightcoin is generated by "miner's mining". Mining is done by hashing with computer graphics card. If the value of "mine burst" is calculated, the system will reward 50 lightcoins at one time. At present, the computing power of lightcoin is growing rapidly, and the miner can't find the mine through several computers. Therefore, it is necessary to join the mine pool, which collects all the computing power, It is estimated that the probability of calculating the "blasting" value is higher
at present, the well-known mine pools include BTCC (original bitcoin China) mine pool, waltc.net fish pool (f2pool), wemineltc, coinotron, silverfish, liteguardian, litecoin pool.org, etc. But at present, the highest income is f2pool. Recently, it launched lightcoin theory income + 10% of mine pool subsidy = your actual income, which has attracted the attention of many miners and the instry

data block chain
litecoin block chain, compared with its competitor bitcoin, can handle larger transaction volume. Due to the more frequent generation of data blocks, the network can support more transactions without modifying the software in the future
as a result, businesses can obtain faster transaction confirmation, and they can still wait for more transaction confirmation when they sell large value procts
Mining has been successful, a total of one equipment (CPU mining, 4-core bar), computing power: 12.75 khash / S (generally abbreviated as KH / s)
KH / S is very rare, so is MH / s; Now the more common are GH / s, th / s, pH / s. The conversion rate is about 1p = 1000t = 1000g = 1000m = 1000K
now the basic unit is GH / s, and several hundred g mining machines are very common
[bitcoin mining machine]
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
According to the domestic bitcoin, lightcoin trading platform bitcoin China and fire coin network quotation: at present, the price of lightcoin is about 58 yuan
recently, e to the FBI auction of bitcoin and the rumor that the Bank of communications will thoroughly investigate the account number of bitcoin trading platform and the impact of bitcoin core developers' outcry for stagnation in the development of bitcoin basic protocol, the prices of bitcoin and lightcoin have dropped. Among them, the price of lightcoin has not been affected by the rising price of bitcoin. The price is moderate and keeps growing slowly. When the price of bitcoin falls, lightcoin still falls

What does this mean? That is to say, how much money you get depends on the effective work you contribute to mining. In other words, the better the performance of your computer, the more money you will be allocated. This is to allocate money according to your work certificate. Most virtual currencies, such as bitcoin, Leyte and Ruitai, are based on the pow mode (the higher the computing power and the longer the mining time, the more money you get)
pos: proof of stake
What does that mean? In short, it is a system to pay you interest according to the amount and time of currency you hold. In the POS mode of certificate of equity, there is a term called currency age. Each currency has one currency age every day. For example, if you hold 100 currencies for 30 days, then your currency age is 3000. At this time, if you find a POS block, Your currency age will be cleared to 0. Every time you are cleared 365 coins, you will get interest of 0.05 coins from the block (which can be understood as 5% annual interest rate). In this case, interest = 3000 * 5% / 365 = 0.41 coins, which is very interesting. Holding coins has interest, very good!
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.
now we can also participate in providing storage space to help those customers who need to store content to keep content fragments, and they will get storage fees; Providing retrieval services, bandwidth, and quickly providing the content customers need will get retrieval fees; Packed blocks, each block confirmed, the network will give a reward. Statistically speaking, the return is higher than that of bitcoin mining.
please take a look at which one you need< br />
(1) starting from the entrepreneurial dream:
1. If you have 100000 pieces of ocean, it's going to be devalued, and you're in the mood to start a business for the first time in your life
2. If you are obsessed with the combination of software and hardware, and want to make some noise, it is more practical to gather 1 million yuan with your partner before holding a meeting
3. Starting after having a good idea and plan can't rely on passion, having goals and then practicing
4. If this idea can be easily realized by yourself and a few small partners, we should try our best to rece the cost of employing personnel, equipment, rent management, etc., and rece the waste of funds
5. The timing is very important. If you think of a great idea comparable to Iwatch today, you should watch the tiger fight in the mountains first
6. If a married female compatriot wants to start a hardware business, she must have her husband's support and participation, and she can share weal and woe again. Of course, the hardware entrepreneurship of single female losers deserves more respect and worship
7. Before you quit your job and start a business, you need to have some private goods in your brain and computer, electronic data chip guidelines, design specifications, supplier directory, contact information and so on. You should pay attention to accumulating them by yourself, but the company's confidential documents should never be retained
8. Find out the target customers and do a proct demand and market research. Don't go to the sea and find that you are the only one to play naked swimming. You'd better hide in the quilt to enjoy yourself
9. Say hello to your colleagues and leaders before you leave and start a business. Maybe when you're in a bad situation, you'll always be helped by your boss, or you can get along well with your boss
10. After going to the sea, roll up your sleeves, open your arms, open your heart, embrace everyone, do everything well from the beginning, and avoid detours< (2) hardware design:
11. A complete project design plan, including: total demand, (alternative) scheme, input and output, etc., will bring endless iterations as you think and change while doing
12. Schematic diagram and PCB should be completed by one person to rece circuit errors and understanding errors, except for large projects requiring division of labor
13. If the chip information is in Chinese, don't be lazy. Find an English version for comparison. Translators often drive cars
14. More than 50% rendancy is reserved for all passive components (resistance, capacitance, inctance, power chip, etc.) rating, and the error of these components is quite frightening under bad conditions
15. The proportion of design errors in PCB packaging, drawings and physical objects of components is always the first, with more than 75% in the instry, which means that most projects have to go through secondary board modification errors
16. When selecting core and relatively new components, sincerely communicate with suppliers face-to-face, including price, supply, business and other details. Don't do it. If you find that there is a shortage, you will feel depressed
17. The bill of materials (BOM) should be standardized and rigorous, with one more letter and one less number. The performance specifications vary greatly to rece the waste of time and money, but the first error rate is still more than 50%
18. Keep in touch with software. Don't be hard at the same time. The more advanced the hardware is, the more software is needed to drive it
19. Learn to subtract, resolutely cut off completely rendant functions, only simple is efficient and reliable, unreliable hardware would rather not, otherwise it will be the beginning of a nightmare< (3) hardware structure and appearance design:
20. Make sure that the front hardware circuit can be put into the final proct you want to make
21. At the beginning of the design, it is very important to consider the battery capacity and choose the size of the battery that the supplier can supply. Do not invent new batteries
22. If the proct structure and assembly are complex, don't be lazy and don't do 3D models and structural assembly drawings. You can design and combine by 2D + three-dimensional imagination. There is really no such thing as a bull with 20 parts
23. MD structure and ID appearance are always twin brothers. They will often PK and promote each other. In the end, they have to compromise and balance for a win-win situation
24. "Design is everything," Qiao said. Proct design (generally refers to appearance design ID) is very important
25. Simple and reliable design is the most important thing. Too many flashy designs are like graffiti
26. A designer who understands raw materials and processing technology is really qualified
27. In the era of popular disassembly testing, the beauty of internal structure is also a kind of user experience
28. Keep enough communication with the mold factory to make sure that what you design can be made by it, even if it's just a structure and appearance
29. Generally speaking, a low-key and luxurious package not only reflects the level of design, but also has the spirit of customer first. Most users resent spending money on exquisite packaging, which is easy to leave a bad brand image< (4) hardware and software driver design:
30. Most hardware procts have a matching heart. If SCM is enough, don't use arm. If single core is enough, don't use al core. If it's enough, it's OK, unless you want to join the nuclear competition
31. The driver design in the heart is best carried out under the guidance of hardware chip manufacturers. Fully understanding the characteristics of hardware is the first step to do a good job of software driver
32. Low power energy control should be considered from the bottom driver. The port that should be closed will be closed, and it will be immediately dormant when it is dormant
33. In case of extremely low temperature, high temperature and external electromagnetic interference, some components will work abnormally, so it is necessary to set program restart or automatic reset, and fully consider error correction and time rendancy
34. The driver is made into a standard upper calling interface, so that when the underlying hardware and driver are replaced, it is not necessary to upgrade the upper program
Part Two: application and operation
(V) software application design:
35. The design freedom of application software is relatively high, but there is a basic theory "experience is king" to abide by
36. In the software and hardware integration project, the application design also needs to consider the interaction with the hardware, the delay caused by communication, the drop of line and other abnormal problems, especially in the domestic 3G network environment
37. If you're still working on PC applications, it's a bit too much. First, focus on the mobile client, and then the PC if necessary
38. Many people worry that IOS is still Andriod. If it's a popular or loser class app, it's recommended that Andriod should do it first. If it's a high rich and handsome fashion proct, it's enough to do well in IOS first
39. Don't occupy too much memory. The configuration can never keep up with the growth rate of the application. When the application is running more and more slowly, the user will think that there is something wrong with your proct, not his mobile phone, which is getting slower and slower, and the configuration is out of date
40. It's not a resounding brand or unnecessary. New applications must not require too many permissions at the beginning. Users will resent that they have to hand over so many permissions to install a new software, and many people will give up the opportunity to experience the proct
41. The application software should be right and good at one time as far as possible. It is deceiving oneself and others to believe that app iterative development. The combination of software and hardware procts, whether the software is not very good or the hardware is not hard, the user is not aware, so the proportion of returns is very high< (6) proct proction and verification:
42. Find a suitable factory to proce samples instead of installing them in the laboratory. The factory will help you find problems
43. Designers and engineers absolutely need to visit the factory in person to complete the preliminary proction with the workers
44. Ask the master worker why not and how to do it. Don't just blame others for being stupid and ignore the irrationality of your design
45. Focus on the defective procts in the early proction, analyze them one by one, and don't be happy because 99% of them are good procts. Perhaps this 1% of the bad reason, in the next proction, will become 100% bad
46. The procts shall be subject to basic high and low temperature, vibration drop and static electricity tests, unless they are only sold in the local market
47. Fatigue test is to let a proct work for 1-10 days under the maximum performance, and count the probability of various crashes and errors< Finally, it is the proct trial test, preparing dozens of procts for different target groups, using them in different states, verifying the adaptability and reliability of the procts, and counting the user experience feedback< (7) enterprise operation:
49. Register the company as early as possible to facilitate all business negotiations. In many places, you can register for 0 yuan, which is the gospel of entrepreneurial losers
50. Find a financial agency to help you with registration, accounting and tax issues, unless you want to experience the fun of queuing and stamping
51. There should be as few shareholders of the registered company as possible (at least one shareholder of the limited company), and the rest should be held by agreement, so as to rece all kinds of cumbersome proceres of subsequent shareholder change
52. Get a good name as soon as possible. It's the label of the brand, which is convenient for memory and dissemination. It's also necessary to check through instrial and commercial registration. It's said that Xiaomi registered after thinking about hundreds of things
53. Since starting a business, don't worry about the office space. Jobs negotiated the first financing in the garage. It must be right to use all that good steel on the blade< (8) legal and financial affairs:
54. Invite an inexpensive legal adviser who is willing to assist, so that the shareholders can attach importance to legal restraint rather than wine and meat alliance
55. Contracts and agreements with important partners and their signing are best approved by the company's legal adviser
56. If you have creative technology, you should protect it in the form of patent, right and other intellectual property rights in time. Maybe you can also apply for government subsidies
57. If the company's business scope involves the interests of exclusive or monopoly enterprises, it is very necessary to make a comprehensive diagnosis of laws and regulations, such as whether health license / medical device certification / qualification identification is needed, and the problems should be avoided in time
58. It's better for the founder to do his own financial work in the early stage of entrepreneurship. He doesn't have much work and has no income. He just turns on the computer to transfer money from his own account and records a flow of water. If the company is registered, then let the agency help to make an external account
59. The founder should have a financial concept at the beginning, learn basic financial knowledge, and be able to carry out simple financial control independently under the guidance of others
60. If there is financing, it is necessary to ask for a professional finance, and investors will generally ask for it< (9) batch and supply chain management:
61. To make friends with the supply chain, no matter whether he is a local tyrant or not, don't take it for granted that he is a customer, he should be someone else's uncle. Sometimes you may have to call them uncle, so it's fair to be friends
62. If you want to make a large batch, you have to face each supplier directly. You can't make it convenient and fun
