How many miners is bitcoin
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
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
1. With the increase of computing power in the whole network, the proportion of computing power owned by miners in the whole network decreases
2. The generation of bitcoin is slowing down. When bitcoin was born in 2009, each reward was 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 bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5. In theory, bitcoin's mining speed has halved in four years.
bitcoin miners will mine 18 million bitcoins this week, and only the remaining 3 million bitcoins will be released before mining stops in 2140 commentators said at the time that the motivation of hoarding bitcoin came from the curiosity in technology. In view of the current price of BTC / USD, financial incentives reverse the activity of bitcoin hoarding by holders in 2019< br />
take bitcoin as an example. Every 10 minutes, all the miners work out a math problem together. Whoever works out the answer first is equivalent to digging into the block and taking it as a reward to get the corresponding bitcoin. Mining equipment is the first to use computers. With the rising price of bitcoin, more and more people participate in mining. CPU mining has graally turned into a professional graphics card. In recent years, it has become a specific mining machine. This evolution is e to the problem of computing power. As I said just now, mining means "all miners work out a mathematical problem together." the higher the computing power, the stronger the hardware computing power and the faster the speed

Survival war is a classic sandbox game. Players can synthesize according to certain rules in the game, but the basis of synthesis is material. Minerals are very important material. So where is the iron ore of survival war? Let's talk about it. I hope it will help you ~
{rrrrrrr}
there is no obvious rule about the distribution of minerals in the survival war game. If players want to dig iron ore, they are advised to take the necessary equipment and find a mine to start digging
there are four necessary tools for exploring a mine cave: spade, knife, torch, earth, and so on, It's better to come out early than to die at home when it's dark. If you come out too early, do something else. You'll have a good time digging in the mine. I don't know the time. You'll pick up a pile of mines and be killed by wolves. All the mines will be finished
Nakamoto's mining is unreliable
On October 31, 2008, a person named Nakamoto published a research report called bitcoin: a peer-to-peer cash payment system on a secret cryptography discussion group, which elaborated the new idea of e-moneysoon after, he developed an operating system for bitcoin issuing, trading and account management on the platform of P2P (peer-to-peer or person to person) peer-to-peer network and distributed database, combining the working mode of open source software and block cipher in cryptography
the system enables all nodes throughout the peer-to-peer network to reach network agreements according to their seed files, so as to ensure fairness, security and reliability in currency issuance, management and circulation
after the advent of bitcoin, it quickly attracted the following and attention of geeks. However, what is puzzling is that after leaving bitcoin in cyberspace, Nakamoto Tsung has not been as frequently active in the bitcoin community as before, but graally faded out of the public's sight
in the spring of 2011, after leaving behind the sentence "I started to do something else", Nakamoto completely evaporated from the Internet space. No one can know his real identity, only that this mysterious figure left 2 million bitcoins for himself in the earliest block he owned, and these bitcoins have not been passive yet
people want to see the true face of Nakamoto, and even use the powerful human flesh search tool to search, which is still fruitless, Even the two Google engineers who later took charge of repairing the bitcoin project claimed that they had never found and met Nakamoto at the scene
extended data mining is a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times
miners provide algorithms for bitcoin network in exchange for the opportunity of bitcoin reward. The miners verify each new transaction and record it in the general ledger
every 10 minutes, a new block will be "mined", and each block contains all the transactions from the generation of the previous block to the present, which are added to the blockchain in turn
we call the transactions included in the block and added to the blockchain "confirmed" transactions. Only after the transaction is "confirmed" can the new owner spend the bitcoin he gets in the transaction
