1. bitcoin is a kind of blockchain
in 2008, Nakamoto first proposed the concept of blockchain as a digital currency, and now blockchain technology has been widely used in various digital currencies
not only bitcoin, such as okex, the world's largest digital currency trading platform, but also its own okb, which is also based on blockchain technology. If you are interested, you can learn about it at okex exchange

2. With the advent of bitcoin, a new technology, blockchain, has come into the public view. What is the relationship between bitcoin and blockchain? The simplest understanding is: blockchain is the underlying technology of bitcoin, and bitcoin is the first generation application of blockchain. Therefore, we often see such a saying that "bitcoin represents the era of blockchain 1.0"
bitcoin is regarded as the first generation application of blockchain technology and the most thorough application of its code testing. However, without bitcoin, there might not be so many people who knew about blockchain now. It can be said that bitcoin has greatly improved the "exposure" of blockchain technology
later, people graally found that the application value of blockchain is far more than bitcoin, but can be applied to many instries to solve the pain points of many instries; The idea of blockchain can also provide a lot of reference for the financial field, which is the real reason for the outbreak of blockchain.

3. Is 5g Huawei digital currency true? 5g Huawei's currency setting is true. At present, Huawei is preparing to blossom and set currency B to face the market
4. Huawei 5g data currency must be a gimmick to cheat some people on the network. Don't believe it
5. In the absence of a clear ban on mining, the fish pond will always serve the majority of miners.
6. Building owners, different procts apply for different projects to provide different information
the information needed for RF is:
2 Sample (s) PCs 3-4 sets (complete set with accessories, frequency interval greater than 1m, need three prototypes of high, medium and low frequency launch and one common launch sample or fixed frequency software)
3 The technical specification includes the following contents:
a Frequency: indicate the frequency range or detailed frequency points
B Movement: working mode, such as FM, HFSS, DSSS, unps, GSM, CDMA, etc.
C Output power
4 User manual
5. BOM list of key components (PCB, wire, etc., UL file No.)
6 Block diagram (antenna should be provided, and the transmitting frequency should be marked at the antenna end)
8 Part layout
9 Circuit description is also called operational description
9. PCB silk screen diagram PCB laout diagram (printed wiring diagram)
10. Charger en60950 test report. En60950 report for adapter
11. Final hardware version, final software version
12. Engineering instruction BT of Bluetooth, WiFi molation for testing
13. Antenna specification (including gain, GSM, WiFi, BT, WCDMA antenna gain)
14, Need to provide cell specification)
15. UL cert for PCB board (flame retardant grade greater than or equal to V-1)
16. Doc countersigned / POA countersigned (when the report is completed)
if it is high-voltage procts, you need more information about key components of safety regulation!

7. Blockchain technology is the underlying technology of bitcoin. Bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted out, which is called blockchain technology or distributed ledger technology. It can be said that bitcoin is the first application of blockchain and will be extended to more and more instries in the future
bitcoin is a virtual digital currency. You can register an account on a professional trading platform and sell or buy bitcoin through advertising. Uto market as a professional bitcoin trading platform, its security, convenience is generally recognized by everyone, the important thing is that the transaction will not charge fees

8. Method 1: enter DFU mode when power on
connect the device to the computer with USB cable, and then you will hear the prompt sound that the computer has been connected successfully
please turn off the device first, and then you will hear the prompt that the computer is not connected successfully
first press and hold the power key to display the apple logo, and then press and hold the on / off key and the home key until the logo disappears. Continue to press and hold the power key for about 4-5 seconds, and continue to press and hold the home key until an iPhone in recovery mode is detected by iTunes (if successful, the iPhone should be in black screen). If redsn0w is used to detect, the device model in DFU will be displayed at the bottom of the interface< Method 2: enter DFU in any state (white apple or unlimited restart)
connect the device to the computer
Press and hold the on / off key and home key directly until the logo disappears. Just follow the above steps
method 3: do not press the key to enter the DFU (it is recommended to use the device with damaged key)
download the firmware of the device corresponding to the latest system version (do not use the firmware that Apple has closed for verification)
Download redsn0w and enter extra even more DFU IPSW in turn
at this time, redsn0w will prompt you that this is the operation of making DFU firmware, not the normal operation of restoring the system. The choice is
after selecting the latest official firmware, redsn0w will start making DFU firmware and wait for completion
Open iTunes, close redsn0w, shift + restore (for Mac, please use option + restore) and select the DFU firmware (prefixed with enter)_ DFU), wait for error 37 in the recovery process. At this time, the device is already in DFU mode.
