QA wastes computing power
with the rising price of bitcoin, more and more people join the bitcoin mining business. Accordingly, mining consumes more and more energy. Obviously, our government is also aware of this
according to the requirements of the document, regulators require local governments to take measures related to electricity price, land use, tax and environmental protection to guide bitcoin miners to withdraw from the business. According to foreign media reports, regulatory authorities are mainly concerned about the money laundering and financial risks involved in the shutdown policy, but excessive power consumption is also a factor that can not be ignored. In principle, bitcoin mining consumes a lot of power because every time a new bitcoin is proced, it needs to solve the complex mathematical problems through the encryption process performed by a high-performance computer. Mining calculation process is used to verify bitcoin transactions in the blockchain to ensure security, but the disadvantage is that it consumes a lot of energy.
we are also most concerned about Suan Li Gang. We need to see whether a company has strength, not only depends on the Suan Li level, but also depends on the single-T burst rate and 24-hour mining efficiency. After all, the amount of money is directly related to our interests
with the coming of the main network of filecoin, the popularity of filecoin continues to increase worldwide, and the price of fil futures has risen rapidly since late May. Some people say that the price of fil currency will soar after the main network of filecoin goes online
we also know that from the perspective of filecoin allocation model, filecoin issued a total of 2 billion pieces, of which 70% were awarded to miners, and the 70% were used to provide data storage services, maintain blockchain, etc; The remaining 30% goes to teams, investors and foundations, with a six-month to six-year unlock period. It can be seen from the distribution model that there were few circulating tokens in early fil, which is also the reason why many people speculate that fil will soar after it goes online
let me give you some suggestions on how to participate. What are China's IPFs companies? How to choose the company and mining machinery
(1) first of all, hardware. We must pay attention to cost performance, rather than blindly choose high or low price. High price does not necessarily bring you income matching with the price. Low price may not be able to participate and lose money
(2) the second is to pay attention to mining strategy. Professional and efficient mining strategy can improve our mining efficiency. Good mining machine with a good mining strategy, you can get a good profit
(3) the third suggestion is to have a professional operation and maintenance team. Our mining machine is placed in the professional IDC room, and we also have our own professional operation and maintenance team, which is of course no problem
if you want to manage by yourself, you must consider environmental factors, such as bandwidth, operation and maintenance, etc. Professional things to professional personnel to do, in order to get better benefits. Another is that in the early stage, the storage is provided by the government or itself, but in the later stage, if the network wants to generate real market storage orders to obtain effective computing power, it also needs a special trading network to provide this service. This has higher requirements for the storage environment and operation and maintenance
(4) the fourth suggestion is to maximize the income of capital allocation. How to understand? That is to say, don't excessively pursue high performance and high storage capacity, because it takes a long time to accumulate effective computing power in the early stage. If a large number of hard disks are invested in one time in the early stage, which takes up funds, but has no effect on the improvement of income, it is a waste. Instead of this, it is better to buy more mining machines in the early stage, and expand the capacity when the storage is full in the later stage. Only in this way can the interests be maximized with the same investment.
blockchain is essentially an encryption algorithm, which is based on the principle of hash 256 bit algorithm to achieve information security; The application of modern information will become more and more global and universal. Besides the basic requirements of anti tampering, anti repudiation and trustworthiness, the protection of privacy needs to be strengthened. The blockchain technology is proced because of the development of modern cryptography. The cryptography used today is the result of cryptography 20 years ago, Therefore, in order to apply the blockchain technology to more participation scenarios, especially in the Internet economy, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed
as long as we use blockchain to make innovations in accounting methods based on our own mode, it will not affect efficiency and waste computing power, but will shorten the time and improve efficiency.
Although many countries do not recognize the value and status of bitcoin, bitcoin is still popular in recent years, and its existence is controversial. Some people say that it has no practical significance, just a number. If it is not officially recognized by the world, mining is a constant waste of energy. Some people say & lt; No one can be sure whether bitcoin is a black horse or not
in fact, bitcoin is calculated and proced through computer networking, also known as mining. At the beginning, there was a personal computer to dig, but the efficiency was relatively low, and the cost of graphics card was low. Then there was a special bitcoin mining machine, ranging from several hundred to two or three hundred thousand yuan
when we talk about bitcoin, we naturally need blockchain because of the blockchain, bitcoin can become bitcoin. It is a secure general ledger for all payments and transactions. It can be said that everyone can contribute to the update. We need to solve a very complex mathematical problem by brute force& mdash; Hash algorithm to complete a block
many people want to know the value of a bitcoin. In fact, the price of bitcoin is changing all the time. We need to check the figures of that day. At present, the price of a bitcoin is less than 30000
the computing power and block output of the whole network can be seen here http://www.taobtc.net/
a lot of computing power is wasted. The reason for this is also from the structure of the P2P pool. The P2P pool node will automatically adjust the difficulty of the pool according to the computing power of the workers' mining equipment. This process is quite fast, and the difficulty will be adjusted every few minutes, As a result, the mining equipment is easy to report errors, that is, it generates a lot of R, which reces the efficiency. The P2P pool is a PPLNs mode. You need to submit an effective share to get profit. After submitting an effective share, you can get all the blocks generated within 24 hours. The difficulty of effective share is relatively large. What I reflected in my pool is that 1g of computing power can't dig effective share at all
how to improve the efficiency of P2P pool
1. First of all, as a node mine pool, the mine pool construction itself needs to add node files, showing the number of connections under the bitcoin wallet. After adding nodes, the number of connections can reach dozens or even more, depending on how many nodes you add, effectively recing invalid share
2. How to fix the calculation difficulty of mining equipment for miners? Set it in your mining equipment startup bat
for example, if your single mining equipment is 10g, you can add
/ 1000 + 10 after the user name (wallet address) in the bat file. For example,
- U
/ 1000 + 10
- P
1 in my bat, what does that mean? That is to say, your device is 10g computing power, and you use a fixed difficulty of 10G for mining in P2P pool. If you are a 1g device, write / 1000 + 1 at the back, so the difficulty is fixed and the efficiency of the device is effectively improved.
feels like bitcoin
has anyone calculated how many kilowatts of electricity bitcoin miners consume every day? The answer from blockchain.info is 23 million kilowatt hours a day. This is a stunning number
the new generation of bitcoin developers will consider how to rece power consumption as an important design goal
there are two directions to achieve this goal. One is to apply computing power to a more meaningful and practical direction. For example, the design of prime currency is to apply the computing power to the search of the largest prime number, which makes the calculation results have scientific value, not just waste on Hash generation. The other is to rece the power consumption per unit of calculation
gridcoin is innovative in both directions. First of all, Gebi applies computing power to grid computing, benefiting from dozens of scientific fields, including life medicine, astronomy, materials science and so on. Secondly, the chip scrypt algorithm will soon be launched in gecoin, which will rece the overall computing power of maintaining transaction and security by about 50%. This is another important innovation of cryptocurrency so far
gridcoin contributes computing power to scientific computing through the Berkeley open network computing platform (BOINC). BOINC is one of the largest grid computing platforms in the world, The famous scientific computing projects based on this platform include
1 SETI@home : search for radio signals from alien civilizations
2 Einstein@Home : looking for the evidence of gravitational wave
3 Rosetta@home Objective: to predict and design protein structure
4. Climateprediction. Net: To study the trend of climate change
5. World Community Grid: distribution hosted by IBM In addition to its official website, BOINC can also visit China distributed computing center
gridcoin fully considers avoiding the infiltration of ASIC, and ensures that only CPU and GPU of computer can mine. Gecoin provides faster transaction confirmation: 2.5 minutes on average. Grid coin's pow algorithm uses scrypt
if the miners of gridcoin are only mining and do not contribute their computing power to BOINC scientific computing platform, the return of each block is only 5 bucks; Correspondingly, in the case of contributing computing power to BOINC, the return of each block will reach 6 to 150 RMB according to the amount of computing power contributed
the total amount of gridcoin is about 168 million, which is calculated according to 100 COINS generated by each block. The actual situation depends on the amount of computing power contributed by the whole network to scientific computing
the official launch time of gridcoin was October 16, 2013, less than two months ago. At present, the computing power is about 50MH / s, and it has increased about twice in December
gridcoin is totally different from counterfeit currency which only changes some parameters. Many senior people who have been tracking the development of cryptocurrency for a long time think that gridcoin is one of the few cryptocurrencies with innovative ability. It has long-term development potential

nitration ore: light white ~
sulfide ore: looks like gold ore. It's easy to get it wrong
Gold Mine: its brightness can be bright on partition walls, so it is easy to recognize ～
diamond mine: diamond. It's prismatic. It's also bright
Obsidian: it's black. There are red dots. Need a diamond draft
How can milk Nuggets dig Obsidian< (1) no Obsidian layer was found. Only the magma ~
you first prepare:
three groups of sand ~
a group of ladders ~
we all know that sand can't be suspended, so we need to use this feature ~
to put sand in the hole you dig, and the sand will fall down, when the sand exceeds the magma layer, You have a foothold in the magmatic layer ~
at this time, you have two ways:
first, look at the location of the sand and jump (Note: don't jump directly on the sand. You'll die ~), climb up your sand with a ladder ~
then you can have a foothold in the magmatic layer ~
the rest is to open the stealth mode ~ expand your platform ~
and then find Obsidian ~
Second, let the sand exceed the magmatic layer, pile the sand to your height ~ then use the ladder to build it down ~ simple
(2) discovery of obsidian layer
there are also two methods:
1. Look at the Obsidian layer and jump down directly. When you get to the Obsidian layer, Press the return button to end the game ～ (Note: the speed of being single for a few years will be reflected) ～ if you go in again, you will be in the Obsidian layer ～ strange refresh is faster ～ be careful ～
② jump to the magma layer next to the Obsidian layer and use a ladder to build the Obsidian layer ～ then you can dig Obsidian happily ～ (Note: Obsidian needs diamond manuscript to dig ～)
the diamond is below-50 underground Fang ~
personally, I feel that the proportion of 70-80 diamonds is relatively high ~
the God of Post Bar recommends the excavation method with high probability of meeting diamonds:
the excavation method with the word "Feng" ~ dig a '| horizontally, and then dig' three '
the "field" excavation method is to dig "ten" first and then "mouth", so as to prevent ore leakage.
The defense and attack of the twilight monster has been increased by three times compared with that of the main world. Please eat carefully. It is suggested that you wear iron jacket or better equipment to prevent being attacked for seconds. You can choose iron axe or iron sword as weapons. The former has high attack enrance and the latter has low enrance. On the contrary, there is no iron ore in the twilight stratum. Before entering, please bring your own iron ore to make iron axe, iron sword, iron bow, etc, Because there are many kinds of canyons in the twilight, you also need to bring stepping stones to cross the road. Another reason is that many people like to dig vertical tunnels. If they accidentally fall down, they can put them up if they are not dead. If possible, they can take conveyor stones to help transport them to the nearby sky Island portal. They can be purchased or they can open a trumpet brush, I really didn't come back from losing all my experience above level 7< br />
Introction to nugget brush Diamond:
nugget diamond can be obtained through mining and trading. It is strictly forbidden to use external swipe in the game. Once cheating is found, there will be severe punishment
first of all, you need to find a cave, whether it's a natural cave or a hole g by others. You can start your mining journey with torches and manuscripts (including diamond manuscripts)
until you find an underground lava pool (rather than a surface lava pool, which is easily confused with the one generated at sea level), it indicates that you are looking for diamonds at the right depth
in addition, there is a bug card diamond, you can try it
first of all, prepare a private storage box with a number of diamonds
put the diamonds in the private storage box, then turn off the wireless network, and take the diamonds out in the moment of turning off. When you log in again, you will find the diamonds you put in your backpack, while the diamonds in the private storage box are still there
this bug is very easy to use at this stage, but it's also unbalanced, so it's best for players not to brush diamonds in this way, otherwise they will lose the fun of the game
