S9 red light of ant miner flashes

1. Hello
What miner are you talking about? Is it the S9 of bitcoin ant miner
if your miner is a small ant series miner, you can rece the noise by changing the fan and appropriately recing the chip frequency. But it's still very difficult to keep quiet.
if you have a large amount of electricity, you can choose a professional hosting mine company for hosting. The electricity charge will be cheaper than that of residents, and you don't need to worry about noise problems, which will cause complaints from neighbors.
if you need anything, you can send a private letter to me

2. 1
if all the cables are connected, we can turn on any connected PC at this time. Turn on the network neighborhood property
2
and then turn on the local connection property
3
and then turn on the TCP / IP protocol property

3. In the first case, the green light is normal. Only a single green light or yellow light flashing, is generally remind can pass, but pay attention to the surrounding situation
in the second case, when the green light flashes at the intersection of traffic lights, it is abnormal, that is, it is broken. At this time, you can pass according to the situation.

4. The temperature is too high: one of the double fans is not running, or the speed cannot reach.

Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

unlike all 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 the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation

the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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

extended data:

bitcoin is the first distributed virtual currency. The whole network is composed of users and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom. Bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

bitcoin requires a private key to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself. Bitcoin can be remitted free of charge, but in the end, a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster execution of the transaction

As a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay. Users can explore the computing power of different hardware on many platforms

6. Certainly. We are members of consensys blockchain. The members of consensys blockchain mainly cooperate in expanding social impact. A number of blockchain projects are working together for the sustainable development goals of the United Nations. Aeternity is an investor in Kora. We will announce the details of the cooperation between KORA and stellar soon. Please look forward to it!

7. Blockchain technology is now involved in many application fields, such as finance, logistics, medical and other instries. For example, blockchain technology uses electronic bills to view all medical bills with one click; For example, the okex exchange can buy digital currency to increase wealth. Blockchain technology is still in development, I believe it can bring more surprises.
