Bitcoin Ethereum filecoin
bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher
Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.
different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum
at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s
the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining
compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.
from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly
The ASIC mining machine of 
bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand
although bitcoin and Ethernet are both digital currencies, unlike bitcoin, the main purpose of Ethernet is not to build itself as a payment substitute, but to facilitate and monetize the operation of Ethereum, so that developers can build and run distributed applications

The building owner mentioned three problems: how to mine, how to earn more, which mining machine is strong. Here is a brief answer
-
how to mine. The way for ordinary investors to participate in mining is to buy mining machines. After the main network line is connected to the main network, they can mine. Generally, mining machine manufacturers will provide hosting services. Mining machines are put in their computer room, and professional personnel will take care of them for you. You don't need to spend much energy on it
-
how to make more money. The first point is to dig the head mine, that is, to participate in the mining within 3-6 months after the main network goes online. Because the number of filecoin is fixed, but the number of miners participating in the mining will be more and more, so the earlier you participate in the mining, the more you get. This can be referred to bitcoin mining. The second point is to choose the right miner. The mining efficiency of different miner is certainly not exactly the same. For companies with strong technology and strength, their miner can dig more in unit time
-
which mining machine is better. This should remind the owner that he should have his own judgment and don't easily believe any miner's words, because now the miner's market is full of fish and dragons, and everyone will say that his family is good, and there are more and more people playing with money to cut leeks. When choosing a miner, directly ask the miner these questions:
1, what's the miner number
2, what is the total storage capacity
3, what is the block rate
4, what is the total yield
5, what is the average yield per T
the real data proves the efficiency of the miner. If the miner can't show the data, it's useless to give you a scrap iron. Identify these five data, which is directly related to your investment and rate of return
< / OL >
that's about it. The second official large-scale developer test is about to start. The owner can pay attention to it. The miner who can get a good place in the test and keep the ranking stable is the miner with real strength and technology. If conditions permit, it's better to visit the company's technical team, computer room, etc
Filecoin is a token on IPFs, and filecoin is a way to reward miners by contributing idle hard disks. Filecoin adopts a new algorithm (workload proof). In short, if you have enough hard disk capacity, the more filecoin rewards you get
The data structure of
IPFs is very simple, but it can be very powerful. It is an immutable data storage, much like blockchain
filecoin involves your idle hard disk in mining, and the bottom layer of filecoin is blockchain. So in mining, we need to do these things:
1. Storage
2. Transaction
3. Retrieval
Mining revenue comes from:
1. Prove the copied data, package transaction
2. Package block
speed is also related, who can make users accept the distribution content faster, who can get higher benefits. So, who has faster bandwidth, more powerful hard disk can have greater advantages. In addition, consensus mechanism plays an important role in hard disk capacity, which is completely different from bitcoin
