How much is it per day for mining in 2018
Now the hottest miner is not bitcoin miner, but filecoin miner. The year can be hot. It's said that the miner will be on the main chain in the middle of the year. Now it's delayed. Now it's said that the miner will be on the main chain in the middle of next year. Many people have bought the miner for a long time, but they are digging other coins, and they can't dig filecoin yet
the cost of mining machinery is neither expensive nor cheap. It takes time to recover capital and make profits. This year's currency market is in downturn, and the cost of digging bitcoin is increasing, but the price has been between us $6000-7000, so there is no profit to cover P>
now mining can only be excavated before the market goes up to sell for money. The average time for the mine to go back is more than 6 months. Next year, whether the market is good or not is still unknown. Moreover, the heat of the digital money has dropped, and the bubble is still very large. p>
It's about 37 yuan
let me first introce the reward mechanism of bitcoin system
bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping
there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years
at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin
about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned

mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
I have been working in this company for one and a half years since May 2018, and I have been outputting works all the time. I seldom output some theoretical articles, so now I want to sort out my understanding of blockchain and how to do design after more than a year's work. There are also some preparations for those who are going to interview with blockchain companies.
now the price of the mine has depreciated by 90%, so it's good to dig up thousands of gold. It's not worth it.
2. I can earn so much even if I go to toss ah for 8 hours, but the market profit is too low to bother
3. At the present stage, Youming iron ore is easy to sell, with a group of 40. But you need a full class number. The lower class can't fly and dig fast.
at this stage, the application projects in the blockchain field are mainly divided into two aspects: one is the new business model that is more compatible with blockchain technology, such as cross-border payment, supply chain finance, proct traceability and other scenarios; The second is the application of the reform based on the existing centralized business, that is, the use of token economic incentive mechanism
with the development of technology, the number of application projects in this field is expanding rapidly, and many people believe that 2018 will be a year when blockchain will really combine with the real economy and break out. However, blockchain technology is still in the early stage of development, facing challenges including regulatory environment, lack of talents, technology awareness and so on
from the technical level, the application of blockchain technology to the actual instry scene needs to solve the problems of transaction speed, data consensus, node maintenance and so on. At present, bitcoin network can only process seven transactions per second, and the leading super ledger technology can only reach the level of 200-300 transactions; This is a long way from a centralized system with tens of thousands of transactions per second. In addition, the lack of relevant incentive mechanism in the field makes it difficult for participating nodes to operate orderly. From the regulatory perspective, although most countries actively embrace blockchain technology, there are no relatively perfect regulatory regulations and instry standards at this stage. Inappropriate regulatory measures may hinder the innovation and development of such emerging technologies
it is affected by many factors, such as the underlying technology needs to be further matured, the lack of intelligent contract public chain platform, the lack of ecological compatibility of all kinds of token, and the unclear government supervision; At present, the implementation of blockchain application projects is relatively slow, and the project quality is uneven. To this end, analysts said that compared with the general blockchain, the focus blockchain for specific scenarios and applications may be a breakthrough in the short term.
