1. bitcoin is an electronic currency proced by open source P2P software. digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin.". Short for: BTC
bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
bitcoin is very similar to cash
the advantages of bitcoin are: no freezing, no tracking, no taxes, and extremely low transaction costs. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
bitcoin, Ethereum, bitcash, EOS, REBO, etc. are the mainstream digital currencies, which can be properly invested. All transactions have risks. You can invest cautiously. You can search online for fire coin, coin security, OK, dobby trading platforms, etc. all of which can trade bitcoin. These are relatively large trading platforms, investing in mainstream digital currencies, and Don't invest in counterfeit money or air money.

2. In a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a way of sequential connection, and it is a distributed account book that can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
nowadays, the mainstream digital currencies are basically developed based on blockchain technology. Blockchain is the underlying technology of digital currency. The domestic tea based digital currency Puyin is developed based on blockchain technology.

3. Blockchain is characterized by decentralization, trust, collective maintenance and reliable database
for example, Sunzi asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would default, so he asked the village head to do notarization and add the account. This is called centralization. But if you don't ask the head of the village, you can shout "I'll lend my grandson 100 yuan! Please put it in the account book. "This is called decentralization. In the past, the village head was highly respected and had a good command of the accounts of the whole village. Everyone kept their money with him. This was the past trust in centralization. Now, everyone is worried that the village head will secretly misappropriate everyone's money. What should we do? So everyone sent an account book to everyone. Anyone who transfers money between them releases information through the loudspeaker. After receiving the information, everyone records the transaction in their own account book. This is called decentralization. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma and other families have ledgers
digital currency is abbreviation of digital currency. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Blockchain technology service upgrade technology

4. 1. Blockchain is an account book for recording digital currency transactions
taking bitcoin as an example, it does not have an entity form, but exists in a special account book. All bitcoin transactions are recorded in the ledger. Through the transaction records, we can calculate the number of bitcoins owned by each user. If a person owns bitcoin, it means that he can find the relevant transaction records in the ledger
the ledger mentioned here is a software that we can download from bitcoin's official website, and the underlying technology used in this software is blockchain. In order to facilitate understanding, we usually say that blockchain is the ledger
the reason why blockchain is used as the underlying technology of ledger is to realize the feature of digital currency decentralization. It can be said that the starting point of a series of problems and solutions of digital currency comes from decentralization
2. Blockchain is a technology to ensure the safe use of digital currency. As we all know, blockchain technology has the characteristics of encryption and non tampering, which can rece the probability of errors in the use of digital currency to 0. Because digital currency requires higher encryption, it must be supported by blockchain technology. At present, not only many instries in China are using blockchain technology, but also many foreign countries are actively using blockchain technology.

5. Blockchain digital currency refers to cryptocurrency. The underlying technology is blockchain. There are many cryptocurrencies. Bitcoin is more famous. Detailed digital currency can be found in cryptofinance mimacaijing.
6. The above formula is not perfect, because the direction of wind speed is not necessarily perpendicular to the action surface θ
F= ρ S(v*sin θ)^ 2
the formula is deced as follows:
consider the case that the wind speed is perpendicular to the action surface first
take the cross section of the wind as s and the length as S Δ x( Δ x-> 0), and the velocity before the wind contacts the action surface is v Δ x=v Δ T
the mass of the air column is Δ m= ρ S Δ x= ρ Sv Δ T
because the mass of the air column is very small, when it collides with the action surface, it will move along the action surface, that is, its velocity perpendicular to the action surface is 0 Δ t=0-(- Δ MV)
i.e. F Δ t= ρ Sv Δ t*v
F= ρ When the wind speed is not perpendicular to the action surface, the velocity is divided into the direction of the vertical action surface and the direction parallel to the action surface. Since the component parallel to the action surface will not generate force with the action surface, the final wind force is only the component perpendicular to the action surface, which is v * sin θ, Substituting this formula into (*) to get
F= ρ S(v*sin θ)^ two
F= ρ S(v*sin θ)^ 2
