Ethereum February 25
At present, there are many channels for domestic users to buy Ethereum. Here are some common channels:
< H2 > 1. Coincola is an over-the-counter trading platform for indivials to trade bitcoincoy Cola is affiliated to Hong Kong coincola limited, which is developed and operated by a professional international team, focusing on providing convenient and reliable blockchain services for global users. Coincola gathers global users and is committed to building a world-class blockchain asset platform
in coy cola, people from different countries can buy bitcoin with their own currency. The seller of the website publishes the advertisement of selling bitcoin, and explains the payment method and exchange rate. You can choose to trade directly online according to the content of the advertisement. Bitcoin is stored in Ke Ying Cola's Internet wallet. You can transfer bitcoin directly
2. How to buy eth
register the coincola account, and then click "buy" in the top menu of the home page to enter the advertisement list page
select the appropriate advertisement from the advertisement list and click "buy eth" to enter the transaction page
enter the amount of money to be purchased or the number of digital currency (please understand the message information of the other party, payment method, and transaction instructions of the platform before entering), click buy now, and the order confirmation pop up. After checking and confirming the information, click confirm purchase to enter the order page
in the chat box of the platform, you can inquire whether the other party is online according to the template statement, and make offline payment according to the collection information and collection method provided by the other party
after the completion of offline payment, click the mark that the payment has been completed at the first time (please complete this operation within 15 minutes at the beginning of placing an order, so as to avoid the payment cannot be recovered e to the cancellation of the order e to overtime), and then customize the input information in the chat box to confirm the payment and ask the seller to confirm the collection and release the digital currency
the progress bar in the top column shows that the goods have been received, indicating that the digital currency has arrived in the wallet. Make comments according to the seller's behavior, and click submit to complete the transaction
with the rapid increase in the number of trading platforms and competitive pressure, many trading platforms will have their own C2C trading. Here we take the relatively large ZB trading platform as an example to illustrate
What is C2C
C2C transaction is a customer to customer transaction, which is guaranteed by the transaction platform. There are many such platforms, such as: Fire coin, otcbtc, bitpai OTC, etc., which are guaranteed by the platform and traded between users. We can simply understand it as: our shopping situation on Taobao is the same as that. In case of dispute, the platform will arbitrate. As long as the transaction is carried out according to the normal process, the security of the transaction is guaranteed
2. ZB's C2C business
ZB platform has two choices: QC and usdt. The basic logic is the same. There are many usdt platforms. QC is the feature of ZB, EXX and other platforms. Here we focus on QC
< H2 > about QCQC is a token. At present, you may know more about usdt and bitcny. At present, there is a special area for QC transaction on ZB. Simply put, QC can buy all other digital currencies (BTC, ETH, EOS, etc.) on ZB. Therefore, after purchasing QC with RMB recharge, you can conct currency transaction on ZB station
The advantage of the < H2 > QC token is that the exchange ratio between the < H2 > < UL >and RMB is 1:1, which is easier to convert
purchasing other tokens with QC can be directly understood as purchasing RMB, and has an intuitive understanding of the currency price
it takes about half an hour to get to the account. It will take about two hours to get to the account in congestion
ZB platform is relatively reliable, and the reputation of ZB is still very good in the past
How to operate C2C of ZB < UL >log in to ZB trading platform and click "C2C trading" on the page
to get to the QC transaction page, you need to first bind your bank card. Then, in the buy QC interface, enter the quantity of QC you want to buy. At present, the ratio of QC to RMB is 1:1. Enter the purchase quantity and click "buy now"
after clicking "buy now", you will be prompted to complete the payment within 30 minutes. At the same time, payment information is generated. Please note that the payment must be made according to the prompt
business processing time 9:00-21:00. Non processing time orders will be processed at 9:00 the next day, and the payment will be completed within 24 hours after receiving the order
this means that the merchant you paid will transfer QC coin to your account within 24 hours. According to my experience, you can get to the account in 2 hours ring the day
< H2 > the following points should be paid attention to:1) make sure to use the newly bound bank card for transfer and payment
2) note information (that 6 digit) must fill in
3) do not use Alipay, WeChat and other transfers. p>
4) do not fill in the opposite account incorrectly
< UL >about 1-2 hours, you can check whether your QC has arrived in the financial center
after the account is received, you can trade in the "QC" zone of the "spot trading". You can choose the transaction you want to buy and buy the order
as of August 23, 2019, Ethereum price: the highest price in 24 hours is ￥ 1922.07 ≈ 0.0365btc, the lowest price in 24 hours is ￥ 1876.36 ≈ 0.0356btc, the highest price in history is ￥ 10047.07 ≈ 0.1906btc, and the lowest price in history is ￥ 2.95 ≈ 0.0001btc 2. Turnover of the exchange: 5.944 billion, 0.62%, 24 hours up and down precautions: 1. The co founders of Ethereum believe that competition will be positive, and the world absolutely needs to see that indivial freedom is respected, and that they can freely access global IT tools. The data of these tools are not controlled by companies or companies that can use digital transformation to increase data
Ethereum is the next generation of cryptography ledger. It intends to support many advanced functions, including user issuing currency, intelligent protocol, decentralized transaction and what we think is the first fully decentralized autonomous organization (Daos) or decentralized autonomous company (DACS) application
Ethereum does not specifically support every single type of function as a feature. On the contrary, Ethereum includes a built-in Turing complete scripting language, which allows you to write code for the feature you want to implement through a mechanism called "contract". A contract is like an automatic agent. Every time a transaction is received, the contract will run a specific code, which can modify the data storage inside the contract or send the transaction. Advanced contracts can even modify their own code
Ethereum was launched on November 1, 2015, and launched on August 22, 2016 on bitcoin trading platform, a well-known domestic trading platform; 30-¥ About 60, current: ￥ 1259.97, the rise is amazing
-
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

expansion:
1. Ethereum is not an organization, but an underlying system that can realize intelligent contract and open source on the blockchain. From its birth to may 2017, Ethereum has more than 200 Ethereum applications around the world in just three and a half years. Ethereum is a platform and a programming language, which enables developers to build and release the next generation of distributed applications
Ethereum can be used to program, distribute, guarantee and trade anything: voting, domain names, financial exchanges, crowdfunding, corporate management, contracts and most of the agreements, intellectual property, and smart assets that benefit from hardware integration. On June 12, 2017, the price of Ethernet currency broke through $400, a record high. From $8 in February 2017 to $400 on June 15, 2017, the price of Ethernet currency has increased 50 times. At the same time, the price of bitcoin has eased, 10% lower than the previous peak, and the price of ether coin is much better; Take over & quot; Bitcoin continues to soar
