1. bitcoin is the practical application of blockchain
when the financial crisis broke out in 2008, a pseudonym named "Zhongben cong" published a paper to improve the story of Lao Wangcun based on blockchain Technology:
1) because bitcoin is global circulation, the "Yuan" in the story was changed into BTC, 100 yuan = 100btc
2) anonymity of bitcoin, Everyone in the story will announce how much money you have in your pocket to the world in the way of accounting. Presumably, everyone is not willing to put it into the account. Everyone in the bitcoin network has a wallet address, which is a code composed of several binary numbers
3) improvement of transaction mechanism and bookkeeping optimization
What are the current application scenarios of bitcoin< At present, the total market value of bitcoin is 967.236 billion, accounting for 50% of the total market value of cryptocurrency. If you are a 20-50-year-old Chinese and have a stable job, you know the news of bitcoin rising from 3000 to 8000 in half a month on the Internet hot search. At this time, you happen to see my article. Then you must think of one thing: should this thing be invested? And the risk
in my opinion, bitcoin is more suitable for fixed investment (if you invest a part of your salary in bitcoin every month, if you get 4000 salary, you can invest 300 at a fixed time point every month). In the cryptocurrency trading market, some people sell their houses because of bitcoin's sudden wealth, while others sell their houses because of speculation in bitcoin, The total market value of the cryptocurrency trading market is not large. There are indeed some experts, big and small, pulling the market, and the change is unpredictable. However, throughout the development of the past 10 years, cryptocurrency still presents a state of benign development, and more and more countries recognize it.

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)
