Mining machinery Jingdong
when you buy a video card miner, go to a local computer dealer and buy a professional chip miner, usually on the mining platform
here are some introctions to the graphics card Mining:
the graphics card mining machine is a computer with 6 medium and high-grade independent graphics cards. The first display card miner is rx470 / rx480. Because it is too hot, AMD's display card manufacturers are in short supply, and the goods are scattered to a few pieces, so many of them are mining with gtx1060, and the 1060 is out of stock. They start mining with gtx1050ti 4G, but there are not many now
1060 is about 0.07 per day, power 1200W +, computing power 125 ~ 135mh / s
1050ti is about 0.05 per day, power 700W, computing power 75 ~ 85MH / s
basically, the price is directly proportional to the performance, maybe 1050ti is slightly ahead, but the combination of 1060 is recommended for single person and single mining
hand printing, without and paste, is adopted.

IPFs is just an underlying technology, a point-to-point distributed file system
filecoin is the incentive layer based on IPFs and blockchain. Only filecoin has token
at present, filecoin is still in the stage of testing network, and there are many mining machines on the market, so whether we can dig out coins or not needs to be marked with a "question mark". At present, it is the stage of test network, and the configuration of future filecoin miner needs to be studied. You can pay more attention to the test network to help you understand the chain of filecoin
you can follow our website for information about filecoin< EM > IPFs force zone < / EM >
there may be a problem with the cable to be replaced,
there may also be a problem with the graphics card driver,
you need to go to the official website or install the appropriate graphics card driver with software such as driver life.
This is exactly the act of fraud by taking advantage of the loopholes in the rules of Jingdong, and this kind of greedy behavior has had a certain impact on the operation of Jingdong digital edition
1. JD doesn't support return of all mobile phones for 7 days without reason
seeing the problem of the subject, I went to JD for a tour and found that not all mobile phones support return of mobile phones for 7 days without reason
in the return rules of Jingdong, it is clearly stated that only the self operated goods of Jingdong can be returned without reason within 7 days, and only some goods can be returned; If it is a third-party business, there is basically no such after-sales service
whether it is apple or JD, their policy starting point is good, they are all in order to give consumers a better consumption experience, but in the end, they have to modify the rules forced by a small number of people. At present, the rule of return without reason only exists in self operated stores. If there are more and more such people, it is possible for Jingdong to cancel return without reason in the future. So don't be greedy for such a small bargain< br />
This is exactly the act of fraud by taking advantage of the loopholes in the rules of Jingdong, and this kind of greedy behavior has had a certain impact on the operation of Jingdong digital edition
Some people's behaviors damage the interests of all peopleno matter the mining machine or the unlimited use of new mobile phones mentioned by the subject, they are actually very indivial behaviors, and the quality of most people is relatively high; However, it is this lost person who abruptly cancels the rule of no reason return, which is especially friendly to consumers
in fact, it's not only jd.com, but also apple in China; Only replace but not repair & quot; But it didn't go on. A large number of people use second-hand mobile phones to artificially create some faults, and then they can switch to a brand-new Apple phone. In the end, this rule seems to have become an instry. A large number of mobile phone vendors this behavior in batches, and sell it again after getting a large number of new mobile phones. The profits can be imagined
in the end, apple cancelled the policy in China, but still provided & lt; Only repair but not replace;, This is understandable
whether it is apple or JD, their policy starting point is good, both are to give consumers a better consumption experience, but in the end, a small number of people forced them to modify the rules. At present, the rule of return without reason only exists in self operated stores. If there are more and more such people, it is possible for Jingdong to cancel return without reason in the future strong>
On April 20, 2020, Alibaba cloud announced that it will invest another 200 billion yuan in the next three years for the research and development of major core technologies such as cloud operating system, server, chip and network, and the construction of future oriented data center
the file system can be accessed in many ways, including fuse and HTTP. Adding local files to the IPFs file system makes them available worldwide. File representation is based on its hash, so it's good for caching. The distribution of files adopts a BitTorrent based protocol. Other users who view the content also help to deliver the content to others on the network
IPFs has a name service called IPNs, which is a global name space based on PKI and is used to build trust chain, which is compatible with other ns and can map DNS,. Onion,. Bit and other IPNs

extended data:
each node uses nodeid as identification, and the node stores the public key and encrypted private key. Technically, dsht based on S / kademlia and coral is used to find the address information of the matching node and the specific node. The small value is directly stored in DHT to generate a nodeid. For larger values, the, IPFs is broken into small blocks, and DHT stores nodeids of nodes that own these blocks
data exchange uses BitTorrent based bitswap protocol to send and receive distributed data blocks. Bitswap maintains two lists, the blocks you want to get and the blocks you have saved. But unlike BitTorrent, bitswap is not limited to blocks in a torrent. Bitswap node can obtain the required blocks from the whole IPFs network
