The calculation force of miner is accurate

1. The difference between mining by Sifang computing power users and mining by mining machines purchased by indivials is as follows:
①. Early stage investment: Sifang computing power provides, which saves users this link. Indivial: purchase of mining machine, selection of mining machine model, preparation of power facilities, etc
2. Field equipment: provided by Sifang computing power, users can save this link. Indivial: rental site, mining machine support rack, noise elimination equipment, etc
3. Software assembly: provided by Sifang computing power, users do not need to master professional knowledge. Indivial: learn professional software assembly knowledge or hire a special person to operate
4. Maintenance: Sifang computing professional technical team, all-weather supervision and maintenance. Indivial: employ professionals to supervise and maintain all day long< (5) electricity and electricity charges: professional large chain mines and users do not need to pay electricity charges. Indivial: the power facilities in the residential area are unstable, the price is high, and the cost-benefit of mining is unbalanced< (6) risk taking: users obtain BTC net assets. Indivial: the equipment investment in the early stage is huge, which is easy to form heavy asset operation, and the income and investment in the later stage are likely to be unequal.

IPFs is a file transfer protocol similar to http. If IPFs wants to run, it needs many computers (storage devices) in the network as nodes. In a broad sense, all participating computers can be called IPFs mining machines

in order to attract more users to join the IPFs network and contribute to the network, an encryption currency named filecoin is designed, which is distributed to the participants (nodes) as a reward according to the amount of contributed storage space and bandwidth. In a narrow sense, the computer specially designed for the purpose of obtaining the filecoin reward is called IPFs mining machine

because IPFs network needs storage space and network bandwidth, in order to obtain the highest profit ratio, IPFs mining machine usually strengthens the storage space and reces the power consumption of the whole machine. For example, more than 10 high-capacity hard disks are equipped, Gigabit or higher speed network cards are equipped, and ultra-low power architecture processors are used

of course, the mining machine provides storage services, so it can obtain revenue. The size of revenue is related to the configuration of mining machinery and the number of IPFs mining machinery

extended data

the reasons why it is not recommended to invest in IPFs are as follows:

1. IPFs technology is too early to be commercialized

IPFs now takes up a lot of bandwidth. IPNs is very slow at present, which is an obvious technical defect. It will be very difficult to realize dynamic web pages only through IPFs

There is no reasonable economic model, even if the token economy is added, it is difficult to realize the long-term natural ecological value

as a very cumbersome decentralized protocol, it is difficult for users to share files autonomously and spontaneously. In addition, even if users share files into the protocol, the files will be completely open and users cannot delete files effectively, so the security of valid files is threatened

the solution is to introce encryption and blockchain incentive mechanism. At the same time, it solves the security and storage power problems of files. However, as mentioned before, any node with workload proof under blockchain incentive mechanism will face an economic problem of continuous power on state

It is difficult to establish an ecological network with IPFs as the core under the influence of technical problems

The ecological application space of

IPFs is quite limited, and the project interaction speed realized by IPFs protocol is also very slow. Of course, it has a direct relationship with the number of nodes and the distance of calling

3. 0.03 bitcoin, about 17 yuan

4. In fact, bitcoin mining can not blindly pursue the size of computing power, but also depends on the overall performance of the miner. For example, the single-mode group of Avalon mining machine 2 will be able to recover its cost in about 40 days, but the 800g recovery time of Avalon mining machine 3 is far away, unless the currency price rises. If you are a retail investor, it is suggested that you buy mining machines with small calculation power and fast cost recovery time, which should be regarded as playing. If you have abundant funds and the ability to set up large-scale mining plants, it is suggested that you buy mining machines with high calculation power and high profits. Avalon's 2.3t miner is said to be coming soon.

5. It's deceptive. It's a typical Ponzi scheme

it is recommended to learn about formal P2P networks such as xiaxinrong.com

6. Yes, it can be exchanged at the exchange.

A: first, block height does not refer to the capacity of the blockchain

Second, the connotation of block height

block height is the number of blocks linked to the main chain, that is, the number of blocks connected to the blockchain

Block height is the indicator of block

2. The block has two identifiers, one is the hash value of the block head, the other is the block height

3. The hash value of the block head is the number obtained by the second hash calculation of the block head by sha256 algorithm

The

block hash value can uniquely and explicitly identify a block, and any node can independently obtain the block hash value by simply hashing the block head

4. Block height refers to the position of the block in the blockchain

The

block height is not a unique identifier
