Ethereum's classic wallet features
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
-
about the variability of blockchain
-
eth, if most people agree to modify the chain, that is, variability, then they can modify the blockchain records and contracts
-
etc, blockchain records and contracts can't be modified, that is, they can't be tampered with
-
here are the advantages and disadvantages of the two methods
The advantage of -
variability is that people can make timely changes to make the right decisions. Therefore, modifying the specification is more practical than finding loopholes
-
non modifiability means that no matter how smart people are at that time, it is impossible not to make mistakes. Therefore, when problems arise in this scheme, it is best to find and solve the loopholes through the existing legal framework
-
differences in development
-
eth, whether it is intentionally arranged or since its birth, the core decisions of blockchain are made by Ethereum foundation with the participation of the community and most of them are developed by it
-
etc, the decision-making of blockchain is mainly decided by the feedback of three loose, collaborative teams with community participation
-
in any case, anyone can put forward improvement suggestions for the two kinds of blockchains. This is the benefit of open source, and it is also very common. You will find that developers of the two chains communicate with each other through GitHub and reddit. I hope to improve the frequency of communication in order to achieve the common goal
-
about compatibility
-
at present, the two kinds of blockchains are compatible with each other. Contracts or applications written by eth can be applied on etc, and vice versa
-
eth, focusing on ewasm, is committed to providing a platform for more and more developers, while the issue of contract security is secondary, such as viper
-
etc focuses on making developers create more secure contracts, such as viper, iohk research, at the cost of consuming the number of potential developers
-
it's obvious that both chains can accept each other, regardless of whether their wishes are the same or not. My view is that the number of developers is not necessarily related to the quality of the proct
-
about the transaction speed
-
eth, the average is 25 seconds, which will be shortened after upgrading
-
etc, with an average time of 14 seconds, maintained at 10-14 seconds after upgrade, according to ecip-1010 and ecip-1036 protocols
-
about the block capacity
-
eth, with the daily trading volume of eth graally reaching 5 million, the block capacity is graally saturated. This situation is similar to the recent transaction cost of bitcoin. This problem can be solved by expanding the block capacity by increasing the default fuel limit
ETC， At present, there is still a lot of room for block capacity. As more and more people accept etc, the block capacity will also increase, just like eth
-
about community
-
eth, mainly discuss on reddit
-
etc, mainly discuss on slack
-
about monetary policy
-
eth, the planned supply is growing steadily, resulting in an average inflation of 3% in eth blockchain in its life cycle
-
etc, before 2025, inflation will reach 3%, and then the total supply will reach 200 million etc, and then there will be deflation
As for the regional distribution of trading volume, China accounts for 20%, South Korea 25% and the United States 25% In etc, China accounts for 50%, South Korea 25% and the United States 10% About securities, at present, investors do not have the option to trade securities. Recently, one of eth's ETFs, trading open-end index funds, was denied by the regulators -
etc owns etc trading trust, which allows investors to own etc instead of the asset itself
etc (Ethereum Classic) is a bifurcated currency that Ethereum hard bifurcates after 1920000 blocks, and its function is very similar to Ethereum. Etc adheres to the concept of decentralization and supports the consensus mechanism of blockchain guarantee. Etc firmly believes that once the blockchain starts to run, its development direction will not be controlled by any central team, but will be determined by the consensus of the people participating in the whole network and the consensus of the computing power of the whole network
the Ethereum blockchain hard branching in July 2016 aims to transfer the Dao funds stolen by hackers to an account controlled by investors, and let the old transaction records be forgotten by history. Most Ethereum developers are involved in the reversal, as are exchanges, startups and other members of the ecosystem. A few days later, the project returned to normal. But not everyone wants to forget the old record. As a result, a small number of miners continued to use the original blockchain as a protest. They described the hard fork as a capital withdrawal for the abandoned project of the Dao. So Ethereum classic (etc) was born
2. Detailed parameters
Chinese Name: Ethereum classic English Name: Ethereum classic English abbreviation: etc
developer: Ethereum Classic team core algorithm: ethash consensus proof: POW
release date: 2016 / 7 / 20 block time: About 15-17 seconds / block
total currency: fixed at 210 million, up to 230 million, Every 5 million blocks decelerate by 20%, and the first proction rection is expected to be in December 2017
main features: independent cryptocurrency
The idea of Ethereum was born in 2013. Vitalik buterin ˙ When he was a programmer in the bitcoin community, he suggested to the core developers of bitcoin to develop a language for application developers to facilitate the development of various applications. Bitcoin core developers disagree. So God V decided to develop a new platform for this purpose
V God wrote the white paper of etheric currency in 2013, in which he explained the goal of building a decentralized program. In 2014, we got development funds through crowdfunding, so we developed the Ethernet system< (better digital currency trading platform "currency exchange")
since its birth, it has carried out four hard bifurcations so far
for the first time, in order to adjust the difficulty
released a stable version of "homeland" for the second time
for the fourth time, in order to prevent DDoS and rece weight
there is only the third hard fork, because of the hacker attack, and forced to fork. This is the Dao event
On July 30, 2015, v-god and Ethereum Foundation created the first smart contract platform and designed the Dao Ethereum contracton April 30, 2016, the Dao smart contract was officially deployed, and the world's largest crowdfunding was completed, reaching an amazing $150 million As an aside, the biggest crowdfunding event in time is EOS crowdfunding, which has reached an even more amazing $5 billion!)
on June 17, 2016, the Dao was attacked by hackers, who stole about 50 million US dollars of Ethernet currency, and the price also plummeted from US $20 to US $15, causing great harm to Ethereum. In order to recover the loss of investors, the community finally decided to hard fork
therefore, on July 20, 2016, at the block height of 1920000, the hard branching was successful, and the new chain is called Ethereum eth, while the original chain is now Ethereum classic etc
Yes, this method is commonly known as "moving bricks"
as long as you put the money in your wallet, you can trade on any trading platform. The BTC price on the coin easy platform is about 10% higher than that on other platforms, and it is suitable for "moving bricks"
at present, digital currency is more like an investment proct, because of the lack of a strong guarantee agency to maintain its price stability, its role as a value measure has not yet appeared, and it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investors
extended data
the characteristics of digital currency
1, low transaction cost
compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment of high handling charges to payment service providers
2, fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization, and it does not need any centralized organization similar to the clearing center to process data, so the transaction processing speed is faster
3, high anonymity
in addition to the physical form of currency can realize the point-to-point transaction without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote point-to-point payment, it does not need any trusted third party as intermediary, and the two sides of the transaction can complete the transaction in a completely strange situation without mutual trust, Therefore, it has higher anonymity and can protect the privacy of traders
But at the same time, it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activitiesask where to eat crabs in Bacheng, any citizen can point out a way. We learned that there are four crab markets and one food street in Bacheng, which is a relatively concentrated place to eat crabs
the crab boat garden in Bacheng is located on Hubin Road by Yangcheng Lake. From Kunshan to Bacheng, just go west along Ma'anshan road and turn right to Hubin Road. Take the highway diners from the exit of the highway Bacheng, along the North West Road has been West to the end, turn right about 1 km road can reach crab Fang Yuan
Xiefang garden is located in the northeast of Yangcheng Lake, beside Xiangshi road. Diners can get off from the exit of Yangcheng Hubei (Bacheng North) of the ring expressway and turn left about 800 meters out of the toll station. The spring and autumn water city crab boat garden has invested about 16 million yuan to build water city catering center, aquatic wholesale market, fishing center and other facilities<
yujiadenghuo catering base is located in Yangcheng Hunan Province, which can be reached from the west to the end along Ma'anshan road. The diners at the exit of Baicheng expressway can walk westward along Chengbei West Road, turn left into Gucheng Road, and then turn into Ma'anshan road to see the lights of fishermen. Fishermen's Lantern investment is 38 million yuan (including 4.2 million yuan for environmental protection), with 46000 square meters of parking space, 2300 meters of catering ship wharf, nearly 100 catering ships, and more than 50% of green coverage
the second market for hairy crabs is also called Bacheng Lake market. You can go north along Weicheng Road, turn to Linhu Road, and go west to Bacheng primary school. The diners who take the expressway take the North West Road to the west, find the Weicheng road and drive north. The second hairy crab trading market has invested 8.5 million yuan in building 139 trading boat docks and 34 catering boats
the food street in Bacheng is mainly operated by the storefronts on both sides of Bajie road and Dayu road. Kunshan diners drive north along Hubin Road and you can see a street full of crab boats. After getting off the expressway, go west to the north of the city and find Hubin Road to find the market. Gourmet street has attracted 89 million yuan of private capital to build 167 business houses, covering a total area of 45500 square meters
of course, if you don't eat crabs in these crab boat intensive crab markets, the old streets in Bacheng town are also a good choice. After eating crab, take a walk in the old street, you can not only eat, but also experience the unique customs of Jiangnan Water Town
some farmhouses and ecological farms scattered in every corner of Baicheng also have authentic hairy crabs. Choose a restaurant you like and try the local farmhouse food. It has a different flavor
recommendation of crab eating restaurant:
a'si crab village in Bacheng, the first sign of crab eating in Yangcheng Lake. The crab village is actually a three story pavilion built by two large barges fixed on the lake. Although it is built on the ship, it is like walking on the ground. The front three floors are all private rooms for eating and seeing the scenery. Behind the crab village are open-air dining places and whole rows of net cages for keeping hairy crabs and fresh Yangcheng Lake aquatic procts. Guests can fish and burn whatever they want< Yangcheng Lake Yangcheng Lake Town: eating crabs on the island, the scenery here is unique
Yangcheng Lake town has two peninsulas, the main island and the lotus island. The annual output of hairy crabs is half of the total output of Yangcheng Lake District. The biggest feature of eating crabs in Yangchenghu town may be that the scenery is better. It's a bit of a paradise to take a motorboat tour of the lake
self driving route: Shanghai Nanjing Expressway Zhengyi hub (the intersection of Shanghai Nanjing Expressway and Suzhou Ring Expressway, turn right) - Suzhou Shanghai Expressway around the city (all the way north) - Shipai hub Yangcheng Hubei exit
3. Yangcheng Lake Weiting Town: eating crabs in food street
Weiting, located in the East Lake of Yangcheng Lake, accounts for one third of the lake area. Walking in the streets of Weiting Town, you can see the "symbol" of hairy crabs everywhere. With a construction area of 56000 square meters, the first phase of the international crab city is the largest specialized market for hairy crabs trading in East China, integrating on-site trading of hairy crabs and domestic and overseas procts, wholesale storage, tourism and catering, and local specialty shopping malls. It is only 20 meters away from the lake, and there is a Weiting hairy crab market with dozens of local crab boats
self driving route: Shanghai - Huning Expressway - entrance and exit of Yangcheng Lake Service Area - Weiting town
Located in the core block of Qianjiang Century City, Xiaoshan District, Hangzhou City, the Expo Center is across the river from Qianjiang New City, adjacent to the Olympic Sports Expo Center (under construction), and seamlessly connected with Yingfeng station of Metro Line 2, sharing the international high-end facilities of shopping, leisure, business, culture, etc. on both sides of the river. The center covers an area of 22745 square meters, with a total construction area of about 300000 square meters. It is composed of three super high-rise tower buildings (building a is the office building, building B is the office building + five-star hotel, and building C is the super high-rise grade A office building). Driven by the al core of Hotel + office, it creates an urban complex integrating five-star hotel, Grade A office building, and boutique business, And make it form microcirculation system among various business forms. Extracted from the essence of Jeffery Holmes, the architectural design master of New York World Trade Freedom Tower, the unique clover architectural shape, combined with the streamlined noble facade, 400-2000 square meters of pure office space, 20 brand high-speed elevator clusters... The top office elements of the city are all gathered here to mark the asset value and corporate image of the synchronous world, making Hangzhou a new generation of world landmark. The project has invited many international architecture and interior design institutions, such as woods Bagot of Australia, BRC and HbAS of the United States, B + H of Canada, etc., and invited Jones Lang LaSalle, one of the world's top five banks, to act as the property consultant, gathering the wisdom and strength of top masters to present the highest level of urban business
