Blockchain labeling
{rrrrrrr}
bitcoin (BTC) is a digital currency with a total amount of 21 million. It has the characteristics of decentralization, globalization and anonymity, just like the Internet. It means that transferring bitcoin to the other end of the earth is as simple as sending e-mail, low-cost and unlimited. Bitcoin is also used in cross-border trade, payment, remittance and other fields
the liquidity and limitation of bitcoin determine that bitcoin can act as a monetary function equivalent to general equivalent, or as a measure of money, but this measure is not a physical measure like gold, but a digital proct
related concepts:
1. Address
the address of bitcoin world looks like this. The address itself is just a string of codes, just like your bank account number 321 million 3288372, which is used to mark an account. Everyone can have countless addresses. The address is public
2. The bank records how much money there is in the bank account
the amount of money in the bitcoin address is recorded by the whole bitcoin network. Each complete bitcoin data will record how many bitcoins are stored in this address
each node participating in the bitcoin network can save a complete of bitcoin data, and everyone has a backup on hand to prevent counterfeiting
3. The key (private key)
the key is another string of characters you only know. The key is used to operate the money in the bitcoin address. Key and address are the relationship between a key and a lock. Each address has only one password, and each password also operates a bitcoin address
with the key, you can control the money in the bitcoin address and pay to anyone. The key should be absolutely safe. The lost or deleted key can never be found, and the money in the corresponding bitcoin address can never be used
the key needs to be kept absolutely secret. Anyone who knows the key can steal all your bitcoin
4. Wallet
the transaction process of bitcoin will involve a lot of complex calculations. In order to simplify the operation, we have made wallets. The wallet has client software on the computer, and also has an online web version. The function of the wallet is to pay with a little touch, and the complicated calculation behind it is left to the wallet to complete
5. Security
if you use the computer client software, you can recommend multibit or bitcoin QT. Both are official software recommendations for the bitcoin community. The installation of these two softwares must be downloaded directly from the official website, and the check code must be checked before and after downloading. This is to prevent someone from tampering with wallet software and stealing keys
6. Mining
about every 10 minutes, some new bitcoin will appear in the bitcoin network, which can be imagined as throwing money in the sky. Whose pocket these scattered money fall into mainly depends on whose computer calculates fast. The faster you calculate, the more likely you are to find the money. Mining is to use the computer to calculate, to pick up the money< br />
as people's misunderstanding of blockchain technology graally dissipates, we will see that next year, the financial services, insurance and medical instries will carry out comprehensive deployment of blockchain technology
blockchain technology will subvert our payment system internationally - the old profit model and other processes will become obstacles, and payment will become faster, cheaper and safer
however, as blockchain becomes more and more mainstream, we can no longer ignore the main obstacles on its development path. For example, the banking instry must develop a clear roadmap for blockchain adoption and cooperate on the basis of global standardization
2, the standardization process is about to start
with the more and more extensive application of blockchain, it will become extremely important to establish standardization methods between each other. But there are complex and political processes that can get in the way - there are conflicts of interest between instry organizations, and companies are trying to gain a clear advantage
with the implementation of various blockchain schemes, we will see that the situation will change to the process of standardization and integration. Once competing organizations graally realize the benefits of alliance and start to accelerate the trade process, strengthen detection and optimize data management
in 2017, there may be only a few dynamic blockchain alliances left, but instry players will have to cooperate and reach an agreement on a flexible and universal open logo. Governments and regulators will also play an important role in protecting consumers and encouraging innovation
stakeholders driving the development of blockchain standards will need to be creative and can envision a future in which these standards can be used to create new and powerful tools
3, fintech is accelerating development
fintech is bringing great changes, from simple payment to complex global financial operations are being subverted by it
the in-depth changes that are expected to happen next year are as follows:
blockchain combined with machine learning can jointly accelerate the existing process and optimize efficiency
emojis, payment, will be more widely used, and mobile devices will become more and more secure
lending network will become one of the hottest areas of blockchain
all countries in the world will be more interested in the development of digital currency
4, it's time to subvert the field of payment
in the field of payment transaction, blockchain technology is used to overcome the problems existing in the agent banking system and international remittance
there are many proceres and incoherent processes in cross-border non cash transactions, which can be eliminated by eliminating the third-party institutions, direct currency transfer and efficient inter-bank settlement. This possibility of creating a competitive market for liquidity providers may ensure the optimal exchange rate for international exchange and payment transactions
payment systems are based on local banking regulations and practices, but lack of common standards, which reces the ability of seamless transmission of data and background information, and brings settlement and non settlement risks
the extensive implementation and use of blockchain will change and subvert the existing financial services instry and payment system on a global scale
in addition, although the blockchain was very popular in 2016, there was very little substantive progress. Only coin Ying China and China Post really put it into practice, and other projects just stayed in the theoretical stage.
Deflection refers to the linear displacement of the axis of the member perpendicular to the axis or the central plane of the shell perpendicular to the central plane when the force or non-uniform temperature changes
the deflection of slender body (such as beam or column) refers to the displacement of each point on its axis in the normal plane of the axis at that point. The deflection of thin plate or shell refers to the displacement of each point on the middle plane normal at this point. The rule that the deflection of each point on the object changes with position and time is called deflection function or displacement function
the deflection observation of building includes the deflection observation of building foundation, building main body and independent structure (such as independent wall and column). For high-rise buildings, when there is a large concentrated load on a small area, it may lead to the settlement of the foundation and buildings. The uneven settlement will lead to the inclination of the building, the bending of local components and the generation of cracks
extended data
1. Deflection calculation formula: ymax = 5ql ^ 4 / (384ei) (EI is the bending stiffness of beam under uniform load q)
deflection is related to load size, member section size and material physical properties of member
Deflection the linear displacement of the centroid of the cross section along the direction perpendicular to the axis ring bending deformation is called deflection γ Expressionrotation angle the angle at which the cross section turns relative to its original position ring bending deformation is called rotation angle θ Expression
The traditional bridge deflection measurement mostly uses dial indicator or displacement meter to measure directly, which is still widely used in bridge maintenance, old bridge safety assessment or new bridge acceptanceDongguan acme logo Technology Co., Ltd. is a limited liability company (solely owned by natural person) registered in Dongguan City, Guangdong Province on January 6, 2015, with its registered address at Room 201, No. 16, Gaopu Garden Road, Gaopu Town, Dongguan City, Guangdong Province
