Ethereum filecoin

1.

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

3. Filecoin is the project with the shortest time and the largest amount of private placement in the history of blockchain. It can make both short-term investment and long-term investment. In contrast, the ecell coin is also good (celletf. IO). ECall is the erc20 token realized through the Ethereum network smart contract. It adopts the block chain technology. All the transaction processes on the chain need the approval of each node in the network, and the whole process is transparent and open.

4. Compared with bitcoin and Ethereum, IPFs miner needs to contribute "hard disk" and "bandwidth". It doesn't need to invest a lot of money in the initial stage to buy expensive hardware to provide computing power, and it doesn't need to spend a large amount of electricity. Filecoin (IPFs) also provides 70% incentive as mining return, which is very sincere in proportion. The hummingbird H1 miner that focuses on interstellar bit is recommended.

5. Who can't boast
IPFs is a basic technology, which can also be used in other projects. What you call IPFs is actually filecoin, which is the incentive layer of IPFs
it's all 2020. Filecoin has not been on the main network yet. Many opportunities have been missed for this efficiency.

6. Let me tell you, EC expects that the consensus will be calculated by each node, so that all nodes in the whole network can reach a consensus in a very short time.

7. For those who need to pay, as a distributed storage network, filecoin is also a platform for the majority of storage consumers
among them, the storage miner provides offline storage space. Users with data storage needs can find the storage miner through filecoin and store their data. In this process, users need to pay a certain amount of fil as the cost of storage. This part of the fee is collected by the storage miner through filecoin.

9. First, the IPFs team is indeed very mysterious in domestic reports
Juan Banet, the founder of the IPFs team, seldom participates in blockchain summit or some offline activities reported in China, and does not have the same high exposure as the founders of Ethereum V God or other project parties. The founders of other projects are often invited to give speeches at regional blockchain summit or serve as platforms for emerging projects. The IPFs team rarely participates in some summit activities held in China, and never provides platform for other projects. According to the official weekly report of ipfs.io, the IPFs team has only organized five community activities in 2018, which are for community enthusiasts, and other meetings are for developers who need to be invited
Second, the filecoin project has not been launched for a long time, and the progress of the project is not very dynamic
according to the blog information on the official website of filecoin, filecoin was crowdfunding on the coinlist platform (a financing platform dedicated to providing initial token issuance (ICO) for certified investors and high-quality blockchain projects) on August 12, 2017. Tens of thousands of investments and excessive traffic also caused some twists and turns in the crowdfunding process of the platform. Since then, a blog notice was sent on September 13, 17, raising more than 205 million dollars in investment. By 2018, the blog has been updated four times, one is a quarterly report on January 1, and the last three are quarterly reports and Q & A in the second half of the year. Compared with other 17 years of crowdfunding projects such as EOS, quantum qtum and omg, filecoin can almost be said to be very low-key and stable
thirdly, there are too many manufacturers selling storage mining machines under the name of IPFs in the market, so it is inevitable that there are black heart manufacturers
e to the rich experience of bitcoin and Ethereum's early miners, many investors who missed the filecoin crowdfunding ICO can think of an investment opportunity to dig filecoin. So a lot of people smell business opportunities in it. For a while, IPFs mining machine manufacturers of various brands have sprung up, but filecoin has not been online for a long time. What should we do? As a result, with the technology vision of IPFs and all kinds of false propaganda, there are generally three types of black heart manufacturers:
the first is to take the equipment with a cost of 300 and sell it at a price of 1000 yuan or even 10000 yuan. Such equipment is often small boxes that look like routers. According to the feedback from the professional team participating in the test of filecoin development network, such a small box can't find filecoin
the second kind of scam is to take the white paper of filecoin, delete and modify it, turn it into a new project, and then sell the exclusive mining machine developed by ourselves. This kind of project side, while selling high priced mining machines, takes out part of the profits and manages the market value of the excavated tokens in the exchange. It can be said that it is a double harvest, which makes it impossible to prevent
the third kind of scam, with the name of cloud computing power and node hosting, has no entity. It mainly sells at a high price through the bonus mode of more than three levels, and over promises revenue and online time. Such a brand can not be found on the Internet, not to mention on the official website
Fourth, the filecoin project has not been launched yet, but the exchange can't wait to launch the futures trading
after learning about the filecoin project, some investors decided to go to the exchange to buy some fils and wait for the currency price of the project to rise. It should be noted that the fils currently traded in the exchange are futures. First of all, the fil purchased here can't be circulated, and it can't be extracted from the personal wallet. It can only be stored in the exchange. Secondly, there are fil6, fil12 and fil36 in the current futures trading, which respectively represent the delivery of filecoin six months, 12 months and 36 months after it goes online. In other words, after the main network goes online, it still needs to wait several months to get the real fil, which still has certain risks
fifthly, many Paolu public chains have written IPFs as their underlying technology into the white paper, which has led many investors who have lost all their money to talk about "IPFs"
among them, there are two projects with relatively high exposure. The first one is filecash coin, or FCC for short. It claims to be the first public storage chain in Hong Kong based on IPFs technology. Its founder, Mr. coin, once made the headlines for throwing paper money on the streets of Hong Kong. At present, the "master coin" has been arrested, and the FCC's official website has been unable to open, and the platform trading has disappointed investors because of the multiple rounds of currency price diving.
