1. 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.

2. First, open the Tencent Smart Security page
and then apply for Yudian terminal security system
and then use the Tencent Yudian to kill the virus

3. 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!

4. What is the relationship between blockchain and bitcoin
blockchain technology is the underlying technology of bitcoin, and bitcoin is the first application of blockchain. As mentioned earlier, the transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain
if we compare the blockchain to a physical account book, then each block is equivalent to a page in the account book. A new account book is generated every 10 minutes, and the transaction information of bitcoin network is recorded on each page. According to the principle of cryptography, each block is connected in chronological order to form a chain structure, so it is named blockchain
since the white paper "bitcoin: a peer-to-peer e-cash system" was born, major financial institutions at home and abroad have been competing to study the underlying technology of bitcoin blockchain and seek the practical application of blockchain technology.

5. Bitcoin market can now be seen on professional software, such as the coin card I use now. I think it's very good. Most of the data are available and updated in a timely manner. I recommend you to download and use it
6. Bitcoin is a kind of digital currency based on blockchain technology, and the simple understanding of blockchain technology is an electronic currency account system realized through point-to-point. It can record every transaction record of bitcoin through the network, and it is decentralized. No one can change it without authorization, so it has a very stable security guarantee for its holders. Blockchain is an incredible great technology in Internet finance. Its inventor "Nakamoto Tsung" has just been nominated as a Nobel Prize candidate by the economic and financial circles.
