What is the technical language of bitcoin

1. 1. bitcoin is a kind of "electronic currency". mining machine is a special bitcoin computing tool for downloading
2. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
3. It's very valuable. In terms of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you will have it. At present, one bitcoin is worth $1044
4. To mine bitcoin, you can download the special bitcoin computing tools, register various cooperation 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 distribute a private key and a public key. You need to back up your 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
finally, I would like to warn you that
bit will one day become US $500000

2. Open source software, see: https://github.com/bitcoin/bitcoin/

3. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. 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. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.

4. blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm for building trust and acquiring rights and interests between different nodes in the blockchain system.

blockchain is an important concept of bitcoin, which is essentially a decentralized database and serves as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access A new distributed infrastructure and computing method for programming and operating data by using intelligent contract composed of automated script code
go language + blockchain training course:
1 What are the advantages of go
advantages of go
1: performance
2: language performance is very important
3: developer efficiency & don't be too innovative
4: concurrency & Channel
5: fast compile time
6: team building ability
7: powerful ecosystem
8: gofmt, Mandatory code format
9: grpc and protocol buffers
can be directly compiled into machine code, independent of other libraries. Glibc version has certain requirements, and deployment is completed by throwing a file
static type language has the feeling of dynamic language. Static type language can check out most hidden problems when compiling, while dynamic language has the feeling that there are many packages that can be used and the efficiency of writing is very high.

5. According to your description, the reasons for voltage instability are as follows:
1. The outdoor power supply line is long, or the external wire section is small, resulting in large line loss. Once the home equipment with large power consumption is turned on (such as inction cooker, refrigerator, air conditioner, etc.), the line voltage drop is large, and the voltage is unstable. It is recommended to call the 24-hour power supply service hotline 95598, and the staff will follow up for you
2. The indoor wiring is unreasonable, the cross section of the main wire is too small, and when the equipment with large power consumption starts, the voltage drop is large, resulting in the instability of the same circuit voltage. It is suggested that for the equipment with large power consumption, separate circuit and separate wiring should be adopted
I hope our answers can help you.

6. Responsibly speaking, the private key is everything. If you keep it yourself, there will be a lot of security risks, such as forgetting, losing and accidentally damaging the device. At this time, you can use a reliable third-party wallet, such as a coin pack. The user password of the coin pack is encrypted with salted sha-512-pbkdf2 high-strength encryption technology and stored on the server. The strength of this encryption algorithm is higher than that of the public key and private key algorithm of the special currency, and the employees of the currency package cannot obtain it. Even if the database is stolen, the user password cannot be cracked.

7. Method / step
1 close the bitcoin client and find the file wallet.dat
WinXP start menu, select "run" and input the following contents: Explorer% appdata% bitcoin
Windows Vista or windows 7, directly input wallet.dat in the "search programs and files" box of the start menu to search
2 right click on the file and select "add to compressed file...", then the following dialog box will appear:
3 set a file name, Check "delete source file after compression"
then click the "advanced" tab:
4 click "set password..." and enter the same password twice in the pop-up dialog box
click "OK" and then click "OK" again to complete the encryption
5 you will see that the original wallet.dat file in the wallet folder is gone, but there is an additional. Rar file
6 encryption is successful
restore wallet
1 you just need to follow the steps of "back up wallet" (described in the previous experience) to open the wallet folder of bitcoin official client
2 the backup wallet.dat file to this folder, and then overlay the original file
precautions
if you use winrar to encrypt the backup, you need to enter the correct password first to restore the wallet.dat.

8. The development language is C + +, and the client interface is QT. It involves P2P, network programming, QT and so on.

9. The total amount is limited, so we can't make fake. Like paper money, many countries don't recognize it, just as they didn't recognize it at the beginning.

10. Most of them use GSLB and distributed server. Bitfirst bitcoin is the platform used. Safe, reliable and trustworthy.
