Technical problems of digital currency exchange
Publish: 2021-04-30 22:32:04
1. After a "thousand exchanges" war in the currency circle, the exchange is now in an unsaturated competition stage, because the moat at the head is not wide enough, the competition barrier is not hard enough, and the competition that everyone wants to win is very big. Globally, the total amount of digital asset trading is a growing market. As the top of the whole instry's food chain, the exchange is marching into a "new continent of the digital world", The market is big enough; With the continuous iteration of technology and the increasing of application scenarios, the needs of users are also constantly diversified, with a hundred flowers blooming and a hundred schools of thought contending, each with its own characteristics. But after all, "safety first"
the security of exchanges is an eternal topic
as the gathering place of interests, the game of interests behind may create evil links. Looking back on the development history of digital currency exchange, we can see a history full of glory and darkness. Glory is that it continues to provide users with more and more trading services and categories. Unfortunately, in the early stage of the instry, there was a lack of system. Most of the traditional exchanges were highly centralized. As the vested interests, they were opaque in assets, unfair in the distribution of interests, weak in the underlying structure, backward in security technology, chaotic in currency rules, and even dark box operation. In order to promote the global blockchain instry into a healthy development state, the market urgently needs an innovative, democratic, transparent, equal, free and safe trading environment to cope with the upgrading and iteration of the blockchain instry and promote the formation of a benign competition pattern in the global exchanges
the endless events tell us that history will not forget the instrial revolution and innovation mission of the blockchain instry, but also the hope brought by the blockchain to the global trust mechanism and the beautiful vision of redefining the world. Because of this, based on our deep understanding of the blockchain revolution and our goal of making a key contribution to the global blockchain business, we are striving to "pick one from a thousand miles" the most reliable blockchain asset trading platform
as an investor in the currency circle, the big knife of asset security is always hanging on his head. We all realize that the currency circle is a place where risks gather, so we don't even have the courage to recommend investment opportunities to our relatives and friends. Not to mention the drastic fluctuations in token trading, even buying and hoarding coins in the exchange are not bold to recommend. Because in the current stage of weak supervision, many exchange accidents and security news emerge in an endless stream, which means that a careless friend's assets will be swept away. When this wave of bear market came, we saw too many exchanges go bankrupt because of poor profits. At this time, conscientious exchanges will return the token to users, but most of them will roll up the token after they declare bankruptcy. There is "Mentougou" before and "fcoin" after. At this time, users react: you want to earn the profits of the transaction, people are interested in your principal. After seeing too much news like this, I seldom recommend buying coins to friends who are interested in investing in the currency circle
until I also experienced the "312" currency disaster in 2020, fortunately, my exchange adopted the circuit breaker mechanism in time to deal with it, so that I reced the panic and cut the flesh. Until now, the market has come back, experienced the return of capital and made profits, I carefully considered recommending this exchange; In this currency disaster, LOEX Lein of this exchange took correct and timely measures to protect the interests of users, won good reputation of users, and stood the test before I really took action and recommended it to my friends
the exchange, which has been operating for two years and has kept a record of zero security failures, has captured the rigid demand of many investors: asset security since its emergence. LOEX always adheres to the principle of user first and safety first, provides users with a safe, stable and convenient digital asset trading platform, and is committed to becoming a leader in the era of digital economy
first of all, LOEX ren operates openly through smart contracts
every user's transaction can be clearly observed through the EOS browser to ensure that your transaction is real. At the same time, because your assets are no longer handed over to the official team of LOEX ren, they are put in a place called "smart contract". Public rules ensure that your assets are smart and your EOS account is free to enter and leave, which ensures the safety of your assets. This is a safe transition to decentralization
next, LOEX also has AI program automatic detection
fault handling: support cluster expansion and active / standby operation
monitoring and early warning: real time monitoring of functional moles and timely early warning of abnormal moles
operation and maintenance center: it has a complete server cluster and database maintenance platform
protection measures: DDoS protection, intelligent ban, remote disaster recovery,
risk control management
we have a cross chain hosting cooperation system
the security system cooperates with Manwu District, know Chuangyu and other well-known enterprises
we have reached in-depth cooperation with the above-mentioned well-known institutions in terms of security. The security institutions provide a series of code audit services for smart contract projects, and continue to provide security audit services after the code upgrade of the project party. At the same time, the organization team will also provide long-term safety testing services to LOEX
therefore, what LOEX can do is secure asset protection, risk screening of currency projects, and security behavior inspection of exchange users
financial management cooperates with famous Wall Street AA level quantitative team
in the future, it can make LOEX exchange more secure and reliable. LOEX cross chain hosting can bring a large number of application scenarios to customers. LOEX exchange can provide sharing depth for all partners of loex.io, so that customers can have better circulation and trading depth in the exchange, and complete safe startup.

Generally speaking, there are not many technologies available for blockchain development. The mainstream development languages are generally divided into the following four types. Different development languages require different timely configuration. You can also visit the blockchain development language selection.

Legal risks faced by digital currency: (1) at the macro level, there are legal risks, systematic risks and consumer protection. At present, the legislative problems of e-commerce and e-payment have not been solved, the concept of e-currency and related provisions need to be clarified, and many laws and regulations have not been followed up. Secondly, there is a systemic risk caused by the collapse of a single issuing institution. If a certain issuing institution loses confidence in e-money e to its poor management, other e-money issuing institutions will also face run risk. Moreover, in the absence of standardized supervision, it is difficult for the public to effectively identify the qualification and credit level of issuers. How to effectively prompt risks and protect the rights and interests of the public has become a difficult problem. In addition, the concealment, rapidity and cross-border nature of Internet payment make e-money an inevitable money laundering tool for criminals 2 At the micro level, there are technical risks and credit risks in the main body of e-money issuance. The issuers of e-money in China include banks, non bank financial institutions, Internet enterprises and other enterprises. Due to the weak financial professional foundation of some issuers, especially the lack of mandatory technical security standards in China, there are serious management loopholes and security risks in e-money issuers. System software or hardware failures will affect the availability of e-money. Secondly, the unreasonable structure of assets and liabilities and high concentration of investment will lead to the lack of liquidity and the risk of default. In addition, the payment and circulation of e-money rely heavily on all kinds of networks, and there are all kinds of operational risks, such as deliberate embezzlement of other people's accounts, internal crimes of issuing institutions and malicious intrusion of hackers, which will damage the interests of e-money holders. Bitcoin, Ruitai and other digital currencies are suitable.

6. Good evening. Nothing special. Graphene is similar to graphite powder, which is one of the isomers of carbon. They all have excellent conctivity. Conctors with good conctivity generally have very good thermal conctivity. Increasing the current through them will proce a lot of heat. Why do you plug a desk lamp into the socket and feel that the wire is not hot? If you plug in a fast heating or inction cooker, you feel that the wire is hot. It's one thing. Graphene comes from carbon, but on the contrary, carbon black is insulating, graphene is conctive, don't confuse it (this is also the reason why graphene far-infrared heater has low power and high heat, which has been called carbon crystal fiber in China). Low resistance, low current, low heat (most common household appliances); Low resistance, high current, high heat (AMD or I society's multi-core CPU, fx-8350, commonly known as inction cooker, do not you want a roast egg?); High resistance, low current, no heating (blocking effect); High resistance, high current, general heat (rice cooker, rice cooker); High resistance, high current, high heat (dormitory enemy "fast heat", hot melting tool for welding PP pipe ends in plumbing pipe fittings).
7. China global currency is an imitation of GEC with the same interface and mode as GEC; It is a new currency trading financial investment platform. China global currency is a kind of virtual currency, which is not protected by law
global currency came out in 2012, it is a kind of cryptocurrency. Universal currency is the first cryptocurrency of certificate of equity type. Cryptocurrency is a kind of digital currency based on blockchain technology. By taking blockchain as the core, building big data and artificial intelligence, global currency makes the cross-border payment scene more perfect, makes the transaction mode have better trust mechanism, and makes the transaction cost and resistance smaller
five ministries and commissions, including the China Banking and Insurance Regulatory Commission, jointly issued the "tips on preventing the risk of illegal fund-raising in the name of" virtual currency "and" blockchain ", pointing out that many criminals, under the banner of financial innovation, use" virtual currency "," blockchain "and" digital currency "to speculate and raise funds, or even engage in illegal activities such as fraud and pyramid schemes
