1. blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. Blockchain is the underlying technology of bitcoin, like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry. In the world of blockchain, it is a very important concept. Many models, such as the maintenance of ledger, the issuance of currency, the design of timestamp, the maintenance of network, the design of competition between nodes, etc., depend on this central idea
the first application of blockchain is bitcoin, and many countries have recognized the legal status of bitcoin. There is no bitcoin organization or the world central bank in the world to issue bitcoin. It relies on Algorithms for credit, an account book and a fair mechanism for testing algorithms and ensuring circulation. It has developed a mechanism that everyone believes in each other. This is the principle of its self-confidence
now people's concept of blockchain is still very general, and its application is not very wide, but in the next decade or even decades, when we talk about blockchain again, it will definitely be the most high-end technology influence, known to all ages!

2. Netizens pointed out that although virtual currency investment has huge risks, it does not mean that blockchain technology also has problems. Blockchain technology can be applied to many fields and scenarios, including some social management scenarios. We should not equate blockchain with bitcoin, but distinguish them
when ordinary people don't understand the relationship between bitcoin and them, technical experts and financial experts have been arguing about the value of bitcoin and the advantages of digital cryptocurrency over existing payment systems. But none of this is important for understanding bitcoin
the only thing you need to know is that bitcoin is just another form of money, that's all.

Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance"
based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects. Bitcoin is a form of blockchain
extended materials
to mine bitcoin, you can download special bitcoin computing tools, register various cooperative websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost<

at this stage, you are cleaning up the illegal and cheating accounts. If you exit, you will dect the money you g in one cycle. Exit cautiously
if there is no response, you can restart the phone, switch to 4G and try again. After logging in to other mobile phones, the previous account will be forced offline.

9. If the grass is orchid, if the wood is pine. The orchid is fragrant and the wind is calm, and the pine is cold, but it doesn't change its appearance.
Bai Juyi, the second head of the pine, loves to move his hand before the pine is full.
the background of the cangran stream is dark, and the clouds are wet and the smoke is falling.
I'm late to grow into a monarch.
How can I plant this few inches of branches in my 40s<
if you want to see the emperor in court, you should plant him in front of the steps.
if you know that you are dead, you will be in the clouds if you don't die.
there are Pines at the bottom of the stream
Bai Juyi is surrounded by pines at the top of a hundred feet,
he was born at the bottom of the stream, which is cold and humble.
there is a dangerous road in the deep mountains,
when he dies old, he doesn't need to work.
the emperor Mingtang owes Liang mu,
there are two unknowns about this and that.
who can describe the meaning of the creation of the universe,
but the material is not the same as the earth.
Jin Zhang Shilu was poor in the original constitution,
the cow's clothes are cheap and Diao Chan's are expensive.
although Diao Chan is different from the cow's clothes,
the high is not necessarily virtuous,
you may not be stupid.

white elm has been planted in the sky.
pine tree
[Tang] Bai Juyi
white pine was planted first, but I didn't plant it.
fortunately, with the help of the westerly wind, you can steal a good voice at night.
Tingsong
[Tang] Bai Juyi
What do you have? Ten pines are my steps.
there are no rows in disorder, and the height is not even.
the height is three feet long, and the bottom is ten feet low.
it's like a wild creature, planted by no one.
it's connected with a green tile house, which inherits the white sand terrace.
it's windy and moonless in the twilight, dry and wet without st and mud.
it's cloudy in autumn and desolate in summer.
it's deep in spring and drizzle in the evening.
it's snowy in the evening, and the branches are covered with jade, Wan Mu is not his peer.
when he bought this house last year, it was most popular.
a family of 20 will be released when they move.
What's the point of moving here, but they have to worry about it.
that is to say, it's a good friend, so why do you have to make talents< I'm still a layman, and my crown takes away the st.
I'm not called the master of pine, and I'm always ashamed.

10. Judgment steps:
1. Whether the head can be up and down after power on. If it can be said that there is no problem with the servo< If you can't get up and down, when you press the up and down buttons, check whether the drive board has output. If so, it means that there is something wrong with the servo motor.
3. If not, it means that there is something wrong with the drive board.
4. If the servo motor is broken, it's relatively simple. Just take it to the electronic city and replace it with another one.
5. You have to find a professional manufacturer or a repairman for the drive board.
