1. blockchain is a disruptive technology. In the case of Internet supporting the release and digital transmission of information, blockchain can identify property ownership, making it unique and traceable
at the same time, it can provide mutual trust for transactions by using trusted self-executive code, so as to rece uncertainty and promote digital transfer and asset transactions
bitcoin is the most well-known blockchain as an encryption currency that uses blockchain technology to realize alternative payment. Bitcoin is a kind of unlicensed blockchain, also known as public blockchain, which does not restrict the identity of users who consume bitcoin or participate in verifying the authenticity of transfer blocks in the blockchain (an energy intensive process, also known as "mining"). These miners get token, or bitcoin, in return, and given that everyone can view the block (though anonymously), the blockchain itself is somewhat transparent
bitcoin is controversial and banned by many countries e to user anonymity to a large extent. However, it is worth noting that the anonymity and energy use of bitcoin are its own characteristics, not the characteristics of the whole blockchain technology.

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.

blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btc4. 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!

5. 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.
