1. Ethereum is an implementation of blockchain. In Ethereum network, many nodes are connected with each other to form Ethereum network:
Ethereum node software provides two core functions: data storage and contract code execution
in each Ethereum node, complete blockchain data is stored. Ethereum not only saves the transaction data on the chain, but also saves the compiled contract code on the chain
At the same time, a virtual machine is provided to execute the contract code
Ethereum virtual machine
Ethereum blockchain not only stores data and code, but also contains a virtual machine (EVM) in each node to execute contract code - it sounds like a computer operating system
in fact, this is the core difference between Ethereum and bitcoin: the existence of virtual machine has brought blockchain into the era of 2.0 and made blockchain a friendly platform for application developers for the first time
the above content comes from the introction course of Ethereum DAPP development
2. Many institutional investors have begun to pay attention to Ethereum. Ethereum also rose and institutional investors have a lot to do with admission. I think Ethereum will go up. The stock exchange proposed to go to Zhongyuan, which is a seven-year-old stock exchange and has never had any security incidents. Trustworthy.
3. Note that Ethereum is 2.0 now. As of 13:57 on the 4th, the current deposit contract address of Ethereum 2.0 has received 1000098eth, and 31252 addresses have completed the mortgage of 32eth. With the increasing number of mortgage, the annual yield of mortgage will graally decrease. After the mortgage amount reaches 1 million eth, the current annualized yield is about 15.7%. Zhongyuan, a well-known exchange, has taken the lead in opening the
mining channel of eth2.0 verification node, and then launched qeth. Users can invest their own eth in verification node mining and exchange qeth to obtain liquidity, and then participate in mining. Compared with the disadvantages of eth2.0, qeth has too many things: the liquidity is guaranteed, the user does not have to bear the technical cost, the threshold of participation does not need 32 eth as low as 0.1eth, the nodes are maintained by the platform, and the income is distributed according to eth2.0.
4. Yes, but it is better to use overseas servers. In addition, the server configuration should be medium or above.
5. Ethereum is not a scam, but there are countless scams designed by criminals around Ethereum. The best way to avoid Ethereum scams is not to trust the guaranteed return on investment and manage your own money bag. Choose a formal
digital currency exchange to invest. At present, the mainstream digital currency transactions in the market are all coin security, fire coin network, bitnet, etc.
6. Generally speaking, undefined index is the exact writing problem in the process of writing. Notice generally prompts for errors that are not directly related to the execution of code, but don't forget that notice sometimes returns some rendant error information
7. There is no problem at all, but relatively speaking, we must buy some reliable ones, because we must pay attention to them.
