How to apply for mobile phone Ethereum Wallet

1.

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 bitcoin

coy 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

< UL >

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

< / UL > < H2 > 2. C2C trading on trading platform

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 QC

QC 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

< / UL > < H2 > official statement:

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

2. This is completely OK. The new account needs real name authentication. If you forget your password, you can get it back again.

3. World of Warcraft mining skills level 1-375 alliance tribe complete upgrade route strategy

1-75: copper ore (smelting experience, can dig 1-4 times) is associated with poor quality stone and malachite
it's easy to dig in the birthplace, plus smelting experience, 50 + mining experience can be easily achieved

75-125: tin ore (smelting experience, can dig 1-4 times) 50 skill requirements, associated with tiger eye stone, shadow stone, rough stone
tin mine is also a very popular mineral. It is recommended by tribes to go to barren land / coniferous forest; The League recommends Chiji mountain

silver ore (smelting experience, can dig 1-4 times) 75 skill requirements, associated with tiger eye stone, rough stone
silver mine is the first rare mine we can encounter. Copper mine generates silver. That is to say, after a certain copper mine is collected, there is a certain chance to refresh silver mine next time. Of course, silver mine is also used as an independent refresh in advanced map. The tribe here recommends barren land / thousand needle stone forest; The League recommends Chiji mountain

125-175: iron ore (can be excavated 1-4 times) 125 skill requirements, accompanied by heavy stones and topaz
there are many places, but none of them is relatively distributed. However, I still suggest to go to the shining plain at the edge of the thousand needle Stone Forest - & gt; Tanalis, there's a lot of data going back and forth on this line

gold mine (smelting experience, 1-4 times of excavation) 155 skill requirements, accompanied by heavy stones and topaz
this is the second kind of rare ore that we can meet, and the last kind of ore with experience in smelting. Iron generates gold. Similarly, after the iron ore is collected, the next refresh will have a certain chance to refresh gold. Of course, the advanced map will refresh, but it is rare

175-245 mitag mine (can be excavated 1-4 times) 175 skill requirements, accompanied by solid stone, turquoise and ruby
two places are recommended for large-scale collection:
1. Barren land, as shown in Figure 1, will brush three secret silver in area a and two secret silver in area B. the refresh of these two places is very fast, and a circle of maps outside can't be finished, so areas a and B will refresh
2. If you think that there are too many people in the barren land, I recommend a small place, the altrank mountains, as shown in Figure 2. In the cave of area a, 2-3 secret silver will be refreshed each time, and in the refresh point outside, 3 mines will be brushed each time. This place has few people, and the map is small, and the refresh is relatively fast, which is suitable for a large number of collection
300-330, mainly to dig the magic iron ore

first of all, dig many magic iron ores distributed on Hellfire Peninsula clockwise

If Hellfire Peninsula is full of miners, go to ZANZA swamp

330-355, mainly for Moxian iron mine and Jiangang iron mine<

going to nagland grassland and digging hard steel ore can not only improve skills, but also sell ore at a good price

at the same time of digging hard steel ore, magic iron ore can also be collected together, even in the later stage, the consumption of magic iron ingot is still considerable

355-375, mainly for Moxian iron mine and Jiangang iron mine

yingyue gorge is the best choice for mining Jiangang mine

if the level is not enough, you can also choose to practice mining skills in the tiroka forest

don't forget to continue to search for magic iron ore while digging hard steel ore in yingyue canyon<

4. The difference of hairy crabs between Yangcheng Lake and Suzhou

5. No, the entry card is still R7 240, and the entry card will not be used for mining, so there is still a lot of inventory, and there will be no new one for the time being

6. Relax and think about the last time you used your wallet, and then where you put it after using it to see if you have any impression. If you are sure that it has been put, will it be stolen or omitted...

7. A virtual currency with a wallet doesn't mean it's more professional and advanced. The existence of digital currency wallet is the premise of currency existence. Currency without wallet can be identified as fraud. Bitcoin, Puyin, Laite, Ethereum, dogcoin and other mainstream digital currencies all exist in wallets, which existed before the release of this kind of currency.

Transaction

the behavior of blockchain transaction follows different rule sets

< UL >

e to the distributed and unlicensed nature of public blockchain, anyone can sign the transaction and broadcast it to the network

according to different blockchains, traders will be charged a certain transaction fee, which depends on the needs of users rather than the value of assets in the transaction

blockchain transactions do not require any central authority verification. It only needs to use the digital signature algorithm (DSA) corresponding to its blockchain to sign it with the private key

once a transaction is signed, broadcast to the network and mined into a successful block in the network, the transaction cannot be recovered

Ethereum transaction structure

Ethereum transaction data structure: transaction 0.1 eth

{
& 39; nonce':&# 39; 0x00', // Decimal: 0
& 39; gasLimit': &# 39; 0x5208', // Decimal system: 21000
& 39; gasPrice': &# 39; 0x3b9aca00', // Decimal system: 10000000000
& 39; to': &# 39;&# 39; ，// Sending address
& 39; value': &# 39; 0x16345785d8a0000',// 100000000000000000 ，10^17
' data': &# 39; 0x', // Decimal representation of null data; chainId': 1 / / blockchain network ID
}

these data have nothing to do with the transaction content, but have something to do with the execution mode of the transaction. This is because when you send a transaction in Ethereum, you must define some other parameters to tell miners how to handle your transaction. Transaction data structure has two attribute designs & quot; gas": & quot; gasPrice",& quot; gasLimit"

" gasPrice": The unit is Gwei, which is 1 / 1000 eth, indicating the transaction cost

& quot; gasLimit": The maximum gas charge allowed for the transaction

these two values are usually filled in automatically by the wallet provider

in addition, you need to specify which Ethereum network to execute the transaction (chainid): 1 represents the Ethereum main network

ring development, tests are usually carried out locally and on the test network, and transactions are carried out through the test eth issued by the test network to avoid economic losses. After the test, enter the main network transaction

in addition, if you need to submit some other data, you can use & quot; data" And & quot; nonce" Attach as part of a transaction

a nonce (number used only once) is the value used by Ethereum to track transactions, which helps to avoid double spending and replay attacks in the network

Ethereum transaction signature

Ethereum transaction involves ECDSA algorithm. Taking JavaScript code as an example, the popular ethers.js is used to call ECDSA algorithm for transaction signature

const ethers = require(' ethers')

const signer = new ethers.Wallet(' Wallet address

signer.signTransaction({

' nonce':&# 39; 0x00', // Decimal: 0

& 39; gasLimit': &# 39; 0x5208', // Decimal: 21000

& 39; gasPrice': &# 39; 0x3b9aca00', // Decimal 10000000000

& 39; to': &# 39;&# 39; ，// Sending address

& 39; value': &# 39; 0x16345785d8a0000',// 100000000000000000 ，10^17

' data': &# 39; 0x', // Decimal representation of null data

& 39; chainId': 1 / / blockchain network ID

})

. Then (console. Log)

you can use the online application composer to deliver signed transactions to Ethereum. This is known as "offline signature.". Offline signatures are particularly useful for applications such as status channels, which are smart contracts that track the balance between two accounts and transfer funds after a signed transaction is submitted. Offline signature is also a common practice in dexes

you can also use online wallet to create signature verification and broadcast through Ethereum account

with Portis, you can sign a transaction to interact with the gas station network (GSN)
