What kind of system is etc mining machine
a brief history of etheric Classics (etc)
etheric classics began with an unfortunate event
in May 2016, the decentralized autonomous organization (DAO) held a token sale with the goal of establishing a blockchain based venture capital to fund future decentralized applications (dapps) in the Ethereum ecosystem
basically, Dao is a complex smart contract that operates in a decentralized way - computer code that automatically performs tasks between multiple parties when conditions are met
despite its ambitious goals and successful token sales, Dao's code has a major vulnerability that allows attackers to steal eth from decentralized organizations
the attacker took advantage of this vulnerability in June 2016, triggering the infamous Dao hacking event, and maliciously stole eth worth about US $50 million
there is no doubt that Dao hacking has shocked Ethereum community and made eth price drop from $20 to $13
after the Dao hacking, the Ethereum community has to choose from three options
< UL >do nothing and try to bear the consequences of the attack; Or
start soft bifurcation to recover funds; Or
deploy a hard fork to recover the lost eth
both soft and hard bifurcations are significant network upgrades. However, soft fork allows users who are not upgraded to communicate with upgraded users, while hard fork is not backward compatible with previous versions
as developers realize that deploying soft forks will expose the network to distributed denial of service (DDoS) attacks, Ethereum community decides to initiate hard forks to recover the funds lost in Dao hacking attacks
although this scheme is supported by most people, a small number of people in Ethereum community oppose it. They think that "code is the law" and blockchain network should be unchangeable
the failure of both sides to reach an agreement on the solution eventually led to the fragmentation of Ethereum blockchain
those who tried to recover the lost eth chose the hard fork and opened the Ethereum (ETH) blockchain as we know it today, while another group stayed on the original Ethereum classic (etc) chain
what problems does ethereal classic solve Ethernet classic (etc) is a blockchain platform that allows developers to deploy smart contracts and dapps although this function is the same as Ethereum (ETH), etc blockchain has two main differences first of all, Ethereum classic community opposes tampering with distributed ledger and supports the view that "blockchain network cannot and should not be modified" secondly, although there is no rigid upper limit on the total supply of eth, it is allowed to create 230 million etc at most by adopting the monetary policy of constant supply as a bonus item, ethereal classic launched Atlantis hard bifurcation last year to increase the interaction with Ethereum and improve the privacy protection of transactions through ZK snarks the trading platforms recommended by etc hot money, okex, AAX, etc
the non-stop toll collection technology is especially suitable for expressway or bridge tunnel environment with heavy traffic. The traditional non-stop toll system with Lane separation measures is usually called single lane non-stop toll system, and the non-stop toll system with free traffic flow without Lane separation is usually called free flow non-stop toll system. The implementation of non-stop toll collection can allow vehicles to pass at high speed (tens of kilometers or even more than 100 kilometers), so it can greatly improve the traffic capacity of the highway; Electronic toll collection can rece the cost of toll management and improve the operation efficiency of vehicles; At the same time, it can also greatly rece the noise level and exhaust emission of toll gate. As the traffic capacity has been greatly improved, the scale of toll stations can be reced, and the infrastructure and management costs can be saved. In addition, the non-stop toll system for the city is not only an advanced toll technology, but also a practical and effective means of traffic management through the economic lever to adjust the traffic flow. For bridges and tunnels with heavy traffic, the non-stop toll system can avoid many weaknesses of the monthly ticket system and manual toll, and effectively improve the fund recovery capacity of these municipal facilities.
Expressway etc refers to electronic toll collection system, which is an automatic toll collection system for expressway or bridge. Through the special short-range communication between the vehicle electronic tag installed on the vehicle windshield and the microwave antenna on the etc lane of the toll station, the computer networking technology is used to carry out the background settlement processing with the bank, so as to achieve the purpose that the vehicle can pay the highway or bridge fees without parking at the toll station of expressway or bridge

detailed rules for handling annual fee of etc credit card
credit card is the biggest one occupying etc market now, because credit card has various kinds of preferential activities. Users should know that there is no charge for etc, but the annual fee of credit card is inevitable. The specific annual fee of etc credit card of each bank is arranged as follows:
1. Instrial and Commercial Bank of China
annual fee rules: ICBC's etc credit card is free of annual fee within the validity period of the card
2. Annual fee rules of China Construction Bank: the annual fee of gold card is 160 yuan, and that of ordinary card is 80 yuan. The annual fee is free for three times of consumption. The other is the etc credit card with auto energy. Although there are car washing and other preferential activities, the annual fee of 200 yuan can not be reced
3. Postal savings bank's annual fee rules: the annual fee of gold card is 125 yuan / year, and that of general card is 50 yuan / year. When a user swipes his or her credit card six times a year, he or she will be exempted from the annual fee for that year's credit card
4. Agricultural Bank of China
annual fee rules: the annual fee of personal platinum card is 580 yuan / year, the subsidiary card is free of annual fee, the first year is free of annual fee, and the next year is free of annual fee after 12 consumption; The annual fee of personal gold card is 160 yuan / year for main card and 80 yuan / year for subsidiary card. There is no annual fee for the first year, and no annual fee for the next year after five times of consumption
Expressway etc refers to electronic toll collection system, which is an automatic toll collection system for expressway or bridge. Through the special short-range communication between the vehicle electronic tag installed on the windshield of the vehicle and the microwave antenna on the etc lane of the toll station, the computer networking technology is used to carry out the background settlement with the bank, so as to achieve the purpose that the vehicle can pay the highway or bridge fees without parking at the toll station of expressway or bridge
it takes less than two seconds for each vehicle to charge, and the capacity of the toll channel is 5 to 10 times that of the manual toll channel. The use of fully automatic electronic toll collection system can make the road toll to paperless and cashless management, fundamentally eliminate the loss of toll tickets, and solve the problem of financial management confusion in road toll collection. In addition, the implementation of automatic electronic toll collection system can also save capital construction costs and management costs

etc system uses vehicle automatic identification technology to complete the wireless data communication between vehicles and toll stations, and to exchange vehicle automatic inction identification and related toll data. Using the computer network to process the charging data, the automatic electronic charging system can be realized without stopping or setting the charging window
etc system carries out wireless communication and information exchange between on-board devices installed on vehicles and antennas installed on toll station lanes. It is mainly composed of vehicle automatic identification system, central management system and other auxiliary facilities
among them, the automatic vehicle identification system consists of on-board unit, also known as transponder or electronic tag, roadside unit, loop sensor, etc. The OBU contains the vehicle identification information, which is generally installed on the windshield in front of the vehicle, the RSU is installed next to the toll station, and the loop sensor is installed under the ground of the lane. The central management system has a large database, which stores a large number of registered vehicles and user information
when the vehicle passes through the toll gate, the loop sensor senses the vehicle, the RSU sends out an inquiry signal, the OBU responds, and carries out two-way communication and data exchange; The central management system obtains the vehicle identification information, such as vehicle ID number, vehicle type and other information, compares and judges the corresponding information in the database, and controls the management system to proce different actions according to different situations, such as the computer toll management system dects the toll from the prepayment account of the vehicle, or sends instructions to other auxiliary facilities
1. It takes less than two seconds for each vehicle to charge, and the traffic capacity of the toll channel is 5 to 10 times that of the manual toll channel
2. It uses computer networking technology to settle accounts with the bank in the background, So as to achieve the purpose of vehicles passing through the road and Bridge toll station to pay the road and bridge fee without parking
3.
for the city, the non-stop toll system is not only an advanced toll technology, but also a practical and effective means of traffic management through the economic lever to adjust the traffic flow.
