Digital currency growth chain

1. 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.

2. If you look closely at these two fields, you will find that they have begun to develop away from each other. Although digital currency is technically inseparable from blockchain, blockchain technology is not limited to digital currency. It is favored by various technical companies in terms of proct traceability, data transparency and distributed consensus. So what impact does the central bank's entry into digital currency have on the blockchain instry, It's not going to change much. At present, the ant gold clothing behind Alipay is the largest patent application company in the global block chain.
what benefits most from this is the domestic currency circle. In 2017, digital currency and related fund-raising activities were banned in China, which is quite negative in the eyes of ordinary people. In fact, the central bank's initiative to explore into cryptocurrency is the recognition of the core concept of digital currency. With this incentive, domestic enterprises will actively enter the instry and inject fresh blood into the instry, which is the most important
about this, you can see the reports of blockchain media, such as golden finance, coin easy to know column, chain news and so on.

3. 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.

4. Blockchain technology is considered as the "golden key" to solve the social credit problem by technical means
I may have heard the saying "artificial intelligence is proctivity and blockchain is proction relationship", which also shows the development potential of regional chain
on the public blockchain, there can be no digital currency. So regional chain fire, digital currency is the same, and the Internet fire is a reason.

5. 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

6. Go to the internet post bar virus bar, there are tutorials. You can also install a Kaspersky (there is a special killing tool). If you can't, go to the computer virus for help. The talents there are more professional

7. Blockchain ≠ digital currency
cryptocurrency (digital currency) is just a proct of blockchain technology. Blockchain is a distributed ledger technology, and cryptocurrency is just a token of a blockchain project
