The company participates in the construction of digital currency
If you want to participate in the transaction of digital currency, you must understand the digital currency ecosystem
It can be said that digital currency exchange is the most important part of the whole instry. Digital currency exchange provides investors and traders with the capital channel to buy and sell digital currency. At the same time, the trading activities of the exchange determine the price of many digital assetsaccording to coinmarketcap, the capital flow of digital currency exchanges is huge, with the average daily trading volume of the top five exchanges exceeding US $3 billion
there are hundreds of digital currency exchanges around the world, some of which operate globally in mainstream markets, while some focus on niche markets
for example, AAX is committed to providing services for digital currency traders and institutional investors, integrating the digital currency world with the global economy, and providing unparalleled first-class technical capabilities using the matchmaking engine supported by lseg technology
many substitutes have successfully occupied a certain market share shortly after their launch. What digital currency exchanges have in common is that they together provide the development soil for these alternative currencies
digital currency is no longer limited to bitcoin. Other digital currency assets, such as eth, XRP, BCH, usdt, LTC, EOS, xtz, etc., have a place in the portfolio and diversification strategies of many digital currency dealers
At present, there are many similarities between digital currency trading and foreign exchange trading, because the basic principles, tools, indicators and strategies used in foreign exchange are also applicable to digital currency trading. AAX College's digital currency trading section discusses these topics in depth and extensivelyblockchain protocol
blockchain is the underlying technology that makes digital currency possible. There are many kinds of blockchain protocols, and the technical characteristics, advantages and disadvantages of each protocol are slightly different
for example, bitcoin blockchain relies on mining and pow (proof of work) mechanism to process transactions, while another blockchain may use dpos (proof of entrustment) mechanism instead of mining. In addition to bitcoin blockchain, other noteworthy protocols include eth, hyperledger, EOS, XLM, Iost, kin, TRX and stem. Among these blockchain agreements, ETH (Ethereum) is commendable in promoting the rapid innovation of the entire digital currency ecosystem
Ethereum platform was created by vitalik buterin, which indicates that developers can make better use of the resources of the platform by using their own programming language solidity. Ethereum has made blockchain technology all the rage, creating a new world of innovative decentralized applications on the basis of smart contracts and custom tokens. At present, most of the substitutes are based on Ethereum's erc20 standard
the district centered financial movement, or defi for short, is also basically based on the Ethereum blockchain agreement
financial services
for every service in traditional finance, Ethereum based defi applications have corresponding alternative versions for everyone to access. The defi app allows users to create stable currencies, lend money and earn interest, send and receive payments, get loans, trade, take positions in the forecast market, enter the real estate sector, and so on. Smart contracts are the key to making decentralized services possible. Once certain conditions are met, the smart contract will automatically perform the pre agreed activities
at the same time, traditional finance also began to provide new customized services for the field of digital currency. At present, some fund managers provide investors with the option of adding digital currency into their portfolios, the trustee provides security services for investors who invest a lot of money in digital currency, and many analysts in mainstream media (such as Bloomberg) also have a strong interest in digital currency
digital currency hardware
for those who like to build their own security measures, the huge digital currency hardware market can provide professional traders and long-term holders with the tools they need. Trezor and ledger are the most famous hardware wallets. They essentially provide the same value for digital currency traders, that is, a more secure way to store digital currency
of course, digital currencies stored in hardware wallets cannot be traded in the market. Therefore, digital currency traders usually allocate funds between the hardware wallet and the exchange according to a certain ratio according to their own trading style preference
There are so many activities ofdata aggregators and blockchain analysis
cross blockchain, which proces a large amount of data, and also spawns the emergence of sub instries, namely data aggregators and blockchain analysis instries. Companies such as coinmarketcap are the preferred source for quick inspection of digital currency and exchange data. They collect statistics on trading volume, liquidity, market value, price trend, circulation and the whole instry, such as the total amount of money, the number of markets, the market value of the instry and the proportion of BTC market value
people who are more interested in blockchain analysis can find the required data in websites like blocktivity. Here, you can view the relevant data of each indivial blockchain agreement, including the number of operations in the last 24 hours, the average number of operations in the last 7 days, the market value and Cui index, that is, the remaining available capacity after the actual usage of the current blockchain agreement. All in all, these websites can provide valuable insights for the blockchain instry
for example, the average number of operations of Ethereum in the past seven days was 667000, with Cui slightly higher than 50%, while the average number of operations of EOS in the same time range was 63 million, with Cui slightly lower than 50%. Technically, the performance of EOS protocol is more powerful than that of Ethereum. However, this can not prevent Ethereum from occupying 70% of the total market value of the most mainstream currencies
digital currency media and conferences
in today's world, almost everyone is the publisher of content. Without we media instry, such a large-scale instry will no longer exist. Digital currency has given birth to a wide range of media patterns, covering news media, KOL and related conferences for currency, public chain and code
digital currency head media include coindesk, cointegration, bitcoin magazine, decrypt, CCN, bitcoinist, newsbtc, etc. Some KOLs are also well-known, sometimes even more popular than the news media
YouTube celebrities, such as datadash, dollar villante, altcoin buzz, Ivan on tech and boxmining, have subscribers from 200K to 300K. In the field of digital currency trading, the top stars of cryptotwitter include venture coinist, cryptocred and cryptodon alt, with 211k, 140k and 120K fans respectively
if you want to have face-to-face communication with companies and people, digital currency and blockchain meetings should not be missed. Every year, there are many conferences around the world for investors, blockchain experts, start-ups, institutional financing, currency or agreement related communities. In 2019 alone, we sponsored and participated in blockchain live in London, the capital summit hosted by coinmarketcap in Singapore and the world mobile conference in Shanghai. We have had exciting meetings with other digital currency companies and major financial institutions, and established contacts with regulators from different jurisdictions
digital currency supervision
with the continuous growth of the market and audience of digital currency instry, in most cases, financial regulators are still developing relevant frameworks to protect investors and consumers. Regulators may take a very different approach, which is a challenge for companies operating across multiple jurisdictions
ring the ICO boom in 2017 and 2018, many projects were launched before the regulatory framework was established, while some projects did not meet the criteria of the jurisdiction and were suspended ring the fund-raising process. All this comes from how to classify digital assets, and the understanding of classification is constantly changing. At present, we divide digital assets into security token and practical token
in the past year, with the proposal of Libra, the promotion of supervision is also increasing. The central bank is also actively exploring the significance of blockchain technology to its policies and economic activities, and constantly publishing reports
the rapid development of digital money ecosystem
these components of digital money ecosystem are growing and developing in an orderly way, contributing to the increasingly sound instry. From the minority interest in 2009 to the active digital asset economy, digital currency has come a long way
However, in order to achieve the development and wide participation of the instry, a strong ecosystem is not enough. We need a better link between digital money and global finance. The better the combination of digital currency and traditional finance, the easier it will be for newcomers to understand the digital currency ecosystemfor every novice, as exchanges, financial services, media and regulators graally adapt to the expectations of mainstream consumers, the digital currency instry will further develop, which may improve investment outcomes
it will be more convenient to pay with digital currency, and it will be more secure for the central bank recently, the Shenzhen municipal government and the Central Bank jointly launched a pilot activity of digital currency. This activity is funded and sponsored by the Luohu District government. This activity will issue digital RMB with a face value of 200 yuan to 50000 Shenzhen citizens, with a total amount of 10 million yuan. These 50000 people will be drawn out in the form of lottery. After winning, they can download the digital currency app and bind it with their mobile phone numbers, It's ready to use. The use scenario is 3389 merchants in Luohu District. Just like mobile payment, you can scan the code directly. Moreover, the design of the digital currency is similar to that of the banknote, with the national emblem and the style of the people's Bank of China on the front
some economists also said that the advantage of digital currency is that its transactions and transfers all have zero cost. For example, some mobile payments, withdrawals and transfers may need some handling charges, but if it is a digital currency, there is no concept of handling charges. With the digitalization of currency, all transactions have zero cost, It is a good thing for enterprises and users
The spacing width of dowel bars is 10 mm
one end of the dowel bar is fixed in one side plate, and the other end can slide in the adjacent side plate. Its function is to transfer traffic load between two pavement slabs and prevent platform staggering, increase the stress transfer between adjacent concrete blocks, so as to prevent uneven settlement of concrete pavement caused by large local stress of concrete pavement, and transfer stress to make adjacent concrete blocks bear stress together
In the calculation, it is assumed that other parameters remain unchanged and the size of the foundation is graally enlarged, and the stress of the slab is graally stable with the increase of the size of the foundation until the stress convergesthrough a lot of trial calculation, the calculation size of the foundation is finally determined as 5.0 M × 7. 0 m × 7. 0 m 75 m in width; The length of slab is generally 4.0 m, 5.0 M and 6.0 M. The length of dowel bar is 450 mm, which is set along the joint center line of concrete slab, and the joint width is 10 mm
contact stress between dowel bar and concrete
the diameter of dowel bar is 32 mm and the length of embedded concrete is 22 cm. The distribution of various contact stresses at the interface between dowel bar and concrete along the length direction of dowel bar is shown in Figure 6. In Figure 6, the horizontal axis is the distance from the center of the seam gap (or the midpoint of the dowel bar). For example, "0" represents the position of the seam, "5" represents the position of the dowel bar 5 cm in the loaded plate, and "5" represents the position of the dowel bar 5 cm in the unloaded plate
the stress distribution along the length direction of the dowel bar is as follows: the maximum contact stress between the dowel bar and concrete is at the joint. With the increase of the distance from the concrete joint, the stress value decreases rapidly, and it is close to 0 at both ends of the dowel bar. In the range of about 8 cm from the joint, all kinds of contact stress values are relatively large. The warping or arching of concrete slab under the action of temperature gradient will lead to the bending of dowel bar
