at present, the vast majority of digital currency transactions are concted in exchanges. Among the numerous exchanges, bitfinex, binance, okex and so on are well-known
However, bitcoin and other digital currencies, as decentralized assets, have to be traded in a centralized exchange, which seems to have hidden contradictions and dangers1. Problems and challenges of stock exchanges=“ //www.yuanxue365.com/en/img_fd039245d688d43fdf16c83b761ed21b0ff43bbf ">
in February 2014, Mt. GOx, the world's largest bitcoin exchange at that time, was stolen 850000 bitcoins, and the price of bitcoin suffered a" cliff "crash on that day. Later, it was revealed that Mt. GOx was in fact a thief, and only 7000 bitcoins were actually stolen
in August 2016, bitfinex, the largest U.S. dollar bitcoin trading platform, suffered a security vulnerability, resulting in the theft of 120000 bitcoins, which was worth $65 million at that time. If converted into the price in December 2017, it would be worth nearly $2 billion
on December 19, 2017, South Korea's youbit exchange was attacked by hackers and lost 4000 bitcoins, and the exchange declared bankruptcy
on December 21, 2017, the Ukrainian liqui exchange was stolen 60000 bitcoins, and the unit price of bitcoin plummeted by US $2000
in 2018, such a drama will only continue
in addition to the threat of hackers, traditional exchanges also have some inherent shortcomings, such as lack of supervision and inefficiency. The security of the exchange for investors can only rely on its own credit, and the cost of running is very low. The stock exchange is regulated at the national level, but there is no such sword of Damocles on the top of the digital currency exchange. Moreover, in an exchange, the same order can only be submitted to one exchange. After the user places an order, the funds used for the transaction will be frozen and can only wait for the completion or cancellation of the transaction. These are undoubtedly inefficient
All in all, the problems of exchanges are the problems of centralization2. Decentralization of exchanges=“ //www.yuanxue365.com/en/img_86d6277f9e2f070889a173c9e224b899a801f257 ">
(1) the progress of the exchange itself
the upgrade of security means is various. At present, the best use is cold wallet, that is, to keep the digital currency in the offline U disk. At the end of 2017, when the YouTube exchange was attacked, 75% of its assets were withdrawn into the cold purse in time to avoid greater losses. However, it seems to be a helpless way to protect the online assets by offline means. Of course, there should be many other methods, which will not be repeated here
(2) the representative of cross ledger transaction is ripple network, and the operating company is ripple labs, which is a semi centralized system. Ripple is a decentralized clearing agreement. In order to solve the high cost and delay of inter-bank clearing, its base currency is XRP. Ripple network can connect all kinds of assets, such as US dollar, RMB, Japanese yen, bitcoin, etc. to its own network. In this system, U.S. dollars or bitcoin can be converted into reborn currency, and then reborn currency can circulate freely in the network, just as a highway is built between various assets. Due to the support of major banking institutions, the reborn currency achieved nearly 300 times growth in 2017
(3) decentralized exchange
some teams try to use blockchain technology to build a decentralized exchange. This kind of decentralized exchange, to some extent, is an extension of cross ledger trading
bitshares is the most representative of early rising projects. It builds a blockchain development platform with servers scattered all over the world. Even if some of them are attacked, the system will not collapse. Anyone can transfer money and borrow money freely on this platform, and can also quickly build a centralized exchange based on this platform. In order to ensure stable value, bitstocks also require three times of digital assets as collateral. At present, bitstocks are running fairly well
later, with the development of Ethereum and smart contract, the x x protocol came into being. This is an open protocol running in the Ethereum blockchain and a decentralized exchange in the Ethereum ecosystem. The agreement has attracted many investors. At present, it has completed financing and started to build open source software tools and infrastructure. Of course, there are many competitors. Ether Delta, IDEX and oasis DEX are trying to provide similar functions. Moreover, it is a smart contract system based on Ethereum, which only supports erc20 token. If other smart contract public chains start to rise, the demand will be reced
in addition, there are some teams that are entering, such as the domestic road seal agreement, looping (LRC) in English. They adopted a design similar to the X protocol, and also introced a fast payment function similar to the lightning network. It is characterized by trying to match multiple exchanges, the user's order can be broadcast to multiple exchanges, and completed by different exchanges. Moreover, the user can still use the account funds after placing an order, and the user's behavior of transferring part or all of the funds is equivalent to partial or total cancellation. To some extent, it improves the breadth and timeliness of the transaction. However, this system seems to have damaged the "power" of the existing exchanges. Whether we can persuade everyone to play together will be a difficult problem
At present, there is still a long way to go for the construction of decentralized exchange. In 3-5 years, traditional exchange will still be the main battlefield of digital currency However, in the future, it is worth looking forward to let the decentralized digital currency get rid of the shackles of centralizationetc is short for electronic toll collection. Etc lane, which is called etc toll platform, is an all electronic toll collection system that uses automatic vehicle identification technology to complete wireless data communication between vehicles and toll stations, to exchange automatic vehicle identification and related toll data, and to process toll data through computer network to realize automatic toll collection without stopping
automatic vehicle identification (AVI) is also called electronic toll collection system (etc). There is no manual charging platform, which is specially supplied to etc vehicles equipped with OBU.
1 Sketch & lt; Talking & gt; The plot is simple. After six years, an old couple, whose son was famous on CCTV, returned to CCTV, but their "thoughts" and "behaviors" changed and remained unchanged. The old lady has become "fashionable", "vain" and "domineering", while the old man is still "not turning over"
2 although the plot is simple, it has profound implications; In my opinion, the old lady is the "elite" and "public opinion", the old man is the "people" and "public opinion", and the host is the "government"
3 two people's "first" appearance is the "fashionable" old lady leading the "clothes", "dirt dregs", the old man who is eating on the stage, which is about the "national conditions"“ The elite and public opinion are well dressed, but they are divorced from the public and public opinion. Food is the priority of the people<
4 the following old ladies "play tricks", "vanity", "false, big and empty" are about the performance of "elite". The clothes rented for 40 yuan a day are said to be bought for 40000 yuan; The "brick pulling tractor" is called "special machine", the "cake baking" is called "large and medium-sized enterprise", and the "no one to buy" is regarded as the "work" of "toilet paper" & lt; Confinement & gt; The signing and selling scenes (in fact, the "elite" themselves squatting in the toilet also know that it is the goods that no one wants) and so on, all of them satirize that the "fake" of "elite" and "public opinion" is not suitable for the national conditions, and the whole child is "cheated"
5 the old lady suppresses the old man and does not let the old man "speak" or "tell the truth". What she says is that "elite" and "public opinion" rape "the people" and "public opinion". What is ironic is the phenomenon that has happened in China: first, the old lady does not like to hear what the old man says (of course, the people do not like to hear what the elite says); Second, we should "suffocate" (if we do not let the common people speak, the common people must "suffocate"); Third, the old man had no place to reason, so he had to scold the host secretly (the government became the scapegoat); Fourth, the host didn't listen and thought that the old man praised him (the government didn't understand public opinion, of course "silly" like "puppet")<
6 the results of the old lady (Elite) who "put on a show", "vanity", "false, big and empty" are: the ribbon is cut and cut into "a cut" (the state-owned assets and resources are wasted by the "elite"); Singing makes the president of the hospital "Crazy" (the instrialization of ecation and medical treatment makes the president not know what to do); But the old lady (Elite) gets 80, and the old man (public) gets 40, Obviously, the distribution is unfair
7 the old man's "telling the truth" is in sharp contrast to the old lady's "scheming", "vanity", "false, big and empty". The old man (the public) said: your aunt is not your aunt six years ago, and your uncle will always be your uncle! This is to say that the "real" people "and" public opinion "are the reference for the host (government) to make decisions< The host (government) is clear headed. It turns out that "everyone" still has one last sentence. Don't say it. Let uncle play the leading role (let the old man "turn over", respect "the people" and "public opinion")“ When the "elite" is floating, it is at most a "cloud", while the public is not satisfied with the "floating", that is "sandstorm"), sing "Errenzhuan". But the host (government) did not abandon the old lady ("elite" and "public opinion") and asked the old man ("public" and "public opinion") to give the old lady (elite or public opinion) a fan. If the old lady wants to sing ("elite" wants to continue to play a role), she has to "take the initiative" to change her clothes (first peel off the skin and integrate into the "people" or mainstream "public opinion"), so that she can "enjoy with the people" ("harmony" between "elite", "public opinion" and "people" and "public opinion")< To sum up, sketch & lt; Talking & gt;, It is about how to make "elite", "public opinion", "people" and "public opinion" work together to "build a harmonious society" under the guidance of the government. The criticism and rescue of "elite" and "public opinion" also shows that the government will further promote and implement the concept of "scientific outlook on development"
10 therefore, skits & lt; Talking & gt; It is a successful and memorable program in the Spring Festival Gala. If the above interpretation is the original intention of the original writer of the sketch or the government's message of governance, then & lt; Talking & gt; It made me see the future and hope of our country.
2. Some drivers ask whether the etc device needs to be charged. In fact, there is no charging cable for the etc electronic tag. The etc device has a battery inside and uses solar energy outside to charge. Bluetooth is used when charging. It can automatically sense at high speed and does not need to turn on the blue tooth all the time. For solar etc equipment that is not used frequently, it is also recommended to charge once every three months to avoid natural discharge of internal battery of etc equipment
3. For the failure of etc tag caused by battery power loss, you can use crowbar or small slotted screwdriver to pry open the shell of the electronic tag, remove the battery and replace it with a new 18650 battery. When the etc device is out of power, it will not identify whether it has been removed or cause failure.
