1.
In Ethereum, all kinds of transfer and other transaction operations need to be completed by accounts. In the transaction platform, such as currency exchange transaction platform, each transaction needs to have a transaction initiation account and a transaction receiving account. Each account corresponds to an address, and the account name is the label of the address. Use a wallet to manage accounts. A wallet can contain multiple accounts. Of course, you can also create multiple wallets
2. Based on the core idea of bitcoin network, Ethereum project puts forward many innovative technical concepts, including smart contract, account based transaction, Ethereum and fuel.
3. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)
4. How many account addresses can an Ethereum node have at most
A: generally, there is only one account address, otherwise there will be an error! Blockchain itself is unique. If there are multiple account addresses on one node, it violates the fundamental principle of blockchain!

6. The Internet has just begun, intelligent life coming
7. When the mobile phone is lost, it can prevent others from using or swiping the lock screen password. The system allows users to remotely lock on the website. After locking, the security of the mobile phone is greatly improved, and it enters the lost mode to automatically take photos! Remote location and so on!
