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. 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
3. There are many kinds of wallets in the market, which can be divided into desktop wallets, mobile wallets, online wallets, hardware wallets and paper wallets according to the platform; According to whether it is connected to the network, it can be divided into cold wallet and hot wallet; According to the degree of autonomy and the way of interaction with the network, it can be divided into full node wallet, SPV light wallet and third-party wallet
for blockchain wallets, you can see the evaluation of wallets in password finance if you go to the tutorial.

4. The essence of a blockchain wallet is a private key, which is a random hash string. If you have the private key, you have the right to use the wallet. According to the storage method of the private key, it can be divided into cold wallet and hot wallet
cold wallet refers to the wallet where the network can't access your private key. Generally, it will take a notebook to record it. Although it avoids the risk of being stolen by hackers, it may also be lost
a hot wallet is a wallet that can access your private key on the Internet. Hot wallets are often in the form of online wallets, which are not easy to lose, but also have risks.

5. Login in different places will display different login IP, but login is still the same wallet, access is the same wallet address
bitcoin wallet is roughly the equivalent of physical wallet in bitcoin network. The wallet actually contains your private key, which allows you to consume the bitcoin allocated to the wallet in the block chain. Like a real wallet, each bitcoin wallet displays the total balance of all bitcoins it controls and allows you to pay someone a certain amount of bitcoin. This is different from the credit card used by merchants to dect money
the mainstream digital cryptocurrencies such as lightcoin, dogcoin, Ruitai coin and Ethereum all have their own wallets.

6. There are many kinds of digital asset wallets. I'll try to make it as simple as possible
according to whether to run the whole node, it can be divided into full node wallet and light wallet. The full node wallet refers to the wallet that synchronizes all the blockchain data, while the light wallet only retains part of the data related to itself. We usually use the light wallet
according to whether the wallet is connected to the Internet, it can be divided into hot wallet and cold wallet. Hot wallets are wallets that stay online, also known as online wallets. A cold wallet is a wallet that is not connected to the Internet, also known as an offline wallet. It is usually a computer, hard disk or paper with a private key written on it that is not connected to the Internet. Generally speaking, a cold wallet is more secure than a hot one because it is not connected to the Internet and the private key can hardly be stolen
according to the different ways of private key storage, wallet can be divided into decentralized wallet and centralized wallet. Decentralized wallet means that the private key is not stored and managed by a third party, but generated and managed by users themselves. If the private key is lost, it will not be retrieved. The storage of the private key of the centralized wallet is managed by the platform. Users log in with their accounts, and the exchange wallet belongs to this category
at present, the well-known wallets on the market include Bitian, imtoken, Galaxy wallet, Cobo wallet, etc.

7. There are many forms of bitcoin wallets, such as PC or mobile wallet clients, online web wallets, and even small notebooks (paper wallets) or brains (brain wallets) that record the private key of bitcoin. You can choose the right wallet according to your needs
bitcoin wallet can be divided into cold wallet and hot wallet according to the storage method of private key
01. A cold wallet is a wallet that can't access your private key on the Internet
cold wallets often rely on "cold" devices to ensure the security of bitcoin's private key, such as computers that are not connected to the Internet, mobile phones, small notebooks with private key addresses, etc. Cold wallet avoids the risk of hackers stealing the private key, but may face physical security risks, such as computer loss and damage
02. Hot wallet refers to the wallet that can access your private key on the Internet
Hot wallets are often in the form of online wallets. When using hot money package, it is better to set different passwords on different platforms and open secondary authentication to ensure the security of your assets
wallet is actually "a management tool for private key, address and blockchain data".

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

9. Verify that the receiving address is correct and resend the transaction.
10. Xiaobian introces a usdt wallet with high security factor. The reason why the security factor is very high is that in the decentralized mode, the file or private key of usdt wallet can be stored off the network, for example, it can be backed up in the mobile phone, hard disk, U disk, network disk, or even written on paper with a pen
we often hear that users usually store most of their digital assets in cold wallets, mainly for the sake of security, while a small amount of digital assets are stored in hot wallets of exchanges to facilitate trading. Now most usdt wallets are centralized wallets, and users' digital currencies are stored in exchanges. In other words, they are very insecure, Because you don't know your usdt wallet file and private key, the exchange is attacked by hackers or closed by yourself, you can't do anything but watch your money at his disposal
you can master your usdt wallet file and private key, and your currency will never be lost. When you need to trade, you can import it into the decentralized wallet website or the official PC wallet, and then transfer it to the exchange for trading. This is the safest way to ensure that your currency will not be lost
Xiaobian recommends that you use the ethmm wallet, which is a decentralized wallet. Only when you master the usdt wallet file or private key can you enter the wallet for receiving and sending
ethmm wallet can log in from a variety of platforms, such as Android, iPhone and windows
official website of ethmm Wallet: https://www.ethmm.com/
any of the three unlocking modes of cold wallet is the safest and most reliable
[keystore file]: wallet file + password, which can be received or sent by importing the website supporting decentralized wallet or official PC wallet
[mnemonics]: mnemonics are random words that can be used to unlock your wallet directly. It is suggested to make more copies on paper
[private key]: a private key is a random unique string that can be directly unlocked for receiving or sending. You can write it on paper with a pen<
say important things three times:
remember to save more copies of your usdt wallet file and private key, such as the backup USB flash disk, mobile phone, computer, and the private key written on paper with a pen
remember to save more copies of your usdt wallet file and private key, for example, in the backup USB flash drive, mobile phone and computer, and write the private key on paper with a pen

Xiaobian sincerely pushes you to use the cold wallet, so that your coin will always be your own. I repeat, as long as your wallet file and private key are not lost, your coin will never be lost

eth1 fragmentation design assumes communication with data fragmentation through beacon chain. If the second phase (phase 2) with multiple execution slices is introced later, then this method will be meaningful. Since the current focus is mainly on the rollup centric roadmap, putting Ethereum 1.0 on a dedicated slice (that is, independent of beacon chain) brings unnecessary complexity to the consensus layer, and increases the delay between publishing data on the slice and accessing them in eth1
we propose to eliminate this complexity by embedding eth1 data (transaction, status root, etc.) into beacon blocks and forcing beacon chain proposer to generate executable eth1 data. This would make eth1 implementation and effectiveness a first-class citizen of consensus.
