Is the number of mining machines rated

1. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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 21 million

2. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.

4. Bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation.

2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

5. Bitcoin mining is to use the computing power of your mining equipment to calculate mathematical problems and confirm transactions. The system will give unequal bitcoin rewards according to the amount of computing power you contribute to the whole network. Bitcoin mining has gone through three stages. In the first stage, we use CPU to mine, because there are few people mining; The second stage, we use the graphics card mining, popular point is burning graphics card mining, players began to wake up; In the third stage, professional ASIC mining machines are used for mining. Starting from Avalon's mining machines and the introction of cat roasting mining machines into the market, the computing power in this stage is surging, and the mining difficulty is increasing. In the following period, new mining machine manufacturers continue to join the mining machine instry. However, with the increase of computing power and the progress of technology, Some mining machinery manufacturers began to go bankrupt or fade out of the market. Avalon has always been active in people's field of vision and constantly launched new chips. At present, Avalon has launched three generations of mining machinery chips, and the fourth generation will soon be launched.

7. Block rewards
as a blockchain, filecoin also needs block procers. Since there are block survivors, block rewards should be given to block procers
how much is the first reward
in the first year, the average reward of a single blockchain is about 145, which graally decreases. In the sixth year, the reward of each block is about 81, which is the reason why the reward of filecoin block is halved in six years
so when the blockchain was just launched, there were 145 rewards for a single block, but there were not so many miners, so it was a very good mining opportunity
What does mining rely on
at present, it doesn't seem to rely on much
how to select block procers
select a number from the previous block, and then hash it with the miner's private key signature. If the hash value meets the conditions, the miner will be selected
this process doesn't need to work hard as bitcoin does, because it only needs to be calculated once, so it seems that high computing power or powerful CPU is useless. Because this algorithm seems to have nothing to do with the pledge space of miners, so as long as the miners meet the conditions, they can be rewarded
storage mining and retrieval mining
as the largest filecoin, this is the driving force of miners' long-term mining. The total number of tokens in filecoin is 2 billion, 70% of which is distributed to miners, that is, 1.4 billion tokens
however, the 1.4 billion tokens need to be subtracted from the block reward tokens to generate the benefits of storage mining and retrieval mining
What are the specific benefits? In fact, it is uncertain, because there are two markets to decide, one is the storage market, the other is the retrieval market. Every miner needs to go to the market to quote, store or search users to find and form orders. So, it's a very dynamic process
this is a bit like the decentralized exchange that we use now. There will be orders or sales orders one by one, and the final platform can only get the average transaction price. And everyone's quotation or order transaction price is different
it should be noted that when filecoin was first launched, there were not too many storage users, so most of the miners' income should come from block rewards. Therefore, it is a major play, which is very worthy of investment
