The classification of Ethereum Wallet

1. Ethereum is an open source public blockchain platform with smart contract function. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin. There are many ways to quickly create Ethereum wallet in daily coin collection. According to the operation, it can be completed quickly. After the creation, you can get free virtual coin directly from the website.

2. Yes, China's bitcoin chbtc mobile app can trade Ethernet / Ethereum eth, which is very convenient and easy to use. It can be downloaded from the official website of China bitcoin chbtc.

3. At present, Ethereum wallet specific development enterprises, such as fiwork mutual metal workshop, are more than one of the software system development enterprises using blockchain technology, and their development schemes are also more reference.

4. No, it only needs the currency supported by the wallet. If the currency not supported by the wallet is transferred in, the coin will be lost. The charging address of each coin is different. Moreover, the wallet is a small platform. I feel that it is not as safe as ZB, but some personal wallets can be used with some amount

5.

in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety

take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:

1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.

firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required

then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers

Second, the bank system verifies the financial level motherboard and encryption chip

uses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area

Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fast

the reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency

Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank you

6. Blockchain wallet is a tool to save the private key of blockchain digital currency. Every digital currency has a wallet. The types of blockchain wallet are as follows:
1. General wallet
can support different blockchain tokens. For example, anmao wallet supports BTC, BCH, LTC, ETH, etc, dash and erc-20 series
2. Main Chain Wallet
in order to achieve their own goals, each coin must establish its own main chain, so that it can carry out business. After the main chain goes online, it needs to use the project's own wallet. Just like the green apple wallet of GAC coin, it is a wallet dedicated to GAC trading and transaction clearing
3. Exchange wallet
there are also wallets in the exchange. If the player's currency is recharged into the exchange, the corresponding currency will enter the exchange wallet. The exchange wallet is almost the same as the ordinary wallet. You can fill in the corresponding wallet address when transferring and withdrawing cash, and the corresponding wallet address will be generated for different currencies of each exchange
4. Hardware wallet
generally speaking, the wallet is software wallet, which is a PC program or app. As the name suggests, a hardware controlled wallet can be connected to the network when it is used, and can be stored off the network at other times, so as to avoid exposing the wallet to the network space.

7.

Generally speaking, blockchain wallet is used to store digital currency. In fact, blockchain wallet does not store digital currency, but a tool to store key (private key and public key). With the key, you can have the right to control the digital currency in the corresponding address, and use the digital currency collection address generated in blockchain wallet, You can accept the digital currency transferred to you by others, and you can also transfer the digital currency you own to others.

classification of digital currency wallets:

can be roughly divided into two categories, hot wallet (online wallet) and cold wallet (offline wallet)

first, hot wallet

Hot wallet is also called online wallet, It includes light wallets and heavy wallets (all node wallets). The wallets that need to be connected to the Internet can be directly traded

1. Light Wallet:

does not store the complete blockchain, only stores the data related to itself. It is small in size and can run on mobile phones, computers, web pages, etc

advantages and disadvantages: it does not occupy memory, supports a variety of digital assets, has a good user experience, is fast for novices, but transaction verification is a little slow

2. HEAVY WALLET (full node wallet)

maintains all blockchain data, completely decentralizes and synchronizes all data. It has better privacy and can verify the validity of transaction data locally

advantages and disadvantages: it has better privacy and faster verification of information, but it needs to synchronize data before each use, takes up a lot of hard disk space, and does not support multiple digital currency transactions

Second, cold wallet

cold wallet is not connected to the Internet, also known as offline wallet; For example, professional hardware devices, or private keys (mnemonics) written on paper

1. Hardware wallet

Hardware wallet is to store digital currency with professional hardware, store the private key of digital assets in a chip, isolate it from the Internet, and plug and play

2. Paper wallet

the advantages and disadvantages of writing the private key on paper and then deleting

cold Wallet:

is relatively safe, but it is very troublesome to create a wallet and trade. It is difficult for novices to operate, and the price of wallets is relatively expensive, generally ranging from thousands to tens of thousands of yuan. If you don't have a large amount of digital assets, you don't need to consider

generally, it's recommended for novices to use light wallet. Light wallet is easy to operate and easy to use. Personal used geekwallet

simple and convenient light wallet supports bitcoin (BTC), lightcoin (LTC), Ethereum (ETH), EOS Storage and management of mainstream digital currency assets such as usdt

using bip44 mnemonics, local private key, off-line signature and other security mechanisms, as well as mobile phone and computer al backup strategy, completely solve the loss of digital currency assets caused by hacker attack, virus infection, mobile phone loss, forgetting mnemonics and other ways, and provide users with online Multi Chain digital assets one-stop management service. The platform also has tiaoshao market, which can carry out token trading of physical assets on the chain

8. 1. Yangcheng Lake - Bacheng: eat the most authentic hairy crabs
ask 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

9. Blockchain wallet is a software to save all kinds of blockchain coins (bitcoin, Ethernet, etc.)
the key and address are the bank card number and password in the blockchain world
the essence of wallet is to save the key, that is, to save the bank card and password
Why do you need wallet to save the password? Unlike the bank card password, the password of blockchain currency is a string of 256 bits of binary numbers without any meaning
there are several terms of Ethereum wallet that must be deeply understood, otherwise it may cause the loss of blockchain assets. These terms are address, password, private key, mnemonic and keystore. Taking bank account as an analogy, the corresponding contents of these five words are as follows:
address = bank card number
password = bank card password
private key = bank card number + bank card password
mnemonics = bank card number + bank card password
keysore + password = bank card number + bank card password
keysore ≠ bank card number
if you forget your wallet information, What are the consequences? There are several situations:
(1) if you forget the address, you can use the private key, mnemonic words and keystore + password to import the wallet to retrieve it
(2) if you forget the password, you can use the private key and mnemonic words to import the wallet to reset the password
(3) if the password is forgotten and the private key and mnemonic words are not backed up, the password cannot be reset and the token cannot be transferred, which is tantamount to losing control of the wallet
(4) if you forget the password, the keystore will lose its function
(5) if you forget the private key, you can export the private key as long as your wallet is not deleted and your password is not forgotten
you can use mnemonic words,
(7) if you forget mnemonic words, you can import wallet to backup mnemonic words through private key and keystore + password
(8) if you forget the keystore, as long as your wallet is not deleted and your password is not forgotten, you can back up the keystore again
mnemonics,
it can be seen from the above that as long as there is a message in "private key, mnemonics, keysore + password", the wallet is there. Therefore, a good backup of "private key, mnemonics, keysore + password" is the most critical
