Serialization of Ethereum

1. 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

2. 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)

3. In fact, the rise and fall of digital currency is a normal situation. The key is to see whether you are optimistic about its long-term value. Relatively speaking, if the long-term value is worth investing in, then the short-term decline can be ignored. At the same time, if you don't know much about digital currency users, it is recommended to choose a reliable and good platform for investment. The investment period needs more than six years, Word of mouth should always be good, you can take a look at AEX, fire coin these two, but also more reliable, you can also understand their own network first

4. You can check the market of Ethereum on non trumpet, but you can't trade it. The trend of Ethereum in the past two years can be described as from heaven to hell, with a very large decline. If you want to invest, you can go to the digital currency exchange. At present, the mainstream digital currency trading in the market includes coin security, fire coin network, bitnet, etc.

5. Ethereum architecture consciousness is the 6-tier architecture of regional block chain. They are: data layer, network layer, consensus layer, incentive layer, contract layer and application layer. I personally feel that the best thing to do in Ethereum development is Shengshi Huacai, which is very professional

6. Where are you going? Wallet or exchange
transfer eth, as long as there is an address, you can transfer it out
mnemonic words are things that you can help to find when you forget your key, not related to money collection.

7. The mps() function performs the same serialization as the mp() function. Instead of accepting stream objects and saving serialized data to disk files, this function simply returns serialized data
the loads() function performs the same deserialization as the load() function. Instead of accepting a stream object and reading the serialized data from a file, it accepts the str object containing the serialized data and returns the object directly.

China's postal code adopts a four level six digit structure. The first two digits indicate the province (municipality directly under the central government or autonomous region); The first three digits indicate the postal area; The first four digits represent counties (cities); The last two digits indicate the delivery office. Postcode is to realize the implementation of automatic mail sorting scheme, because the computer can not recognize Chinese, but can recognize numbers. Code each area, can quickly use the computer sorting, to write the more detailed the better
