Address and use of Ethereum block browser

1. Just focus:
you can't retrieve your assets through Ethereum block query
think too much
if you want to check the real estate,

you can go to the real estate transaction registration center.

2. Ethereum browser's website is etherscan.io, you can query Ethereum related details. At present, the exchanges that can trade Ethereum mainly include: coin an, fire coin, bitnet, etc.

3. What does it mean that there is no verification of the display in the browser and the release contract code? He certainly didn't have time to do it.

4. This has nothing to do with the browser, this need to go to a professional website to query, you can query. Because bitcoin transactions are recorded on the blockchain, there is no way to modify and delete them. However, Google browser is generally used
bitcoin, Ruitai coin, Laite coin, dogcoin and other digital currencies all use blockchain technology.

5. 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. You can view the webpage of blockchain transaction records

7. In a centralized exchange, currency is controlled by them. As long as they want to run, they can run
coins should be transferred to their cold wallets for safety
it is suggested to choose a big exchange with good reputation, so as to rece the risk of running away.

8. 1. Wallets have to be open source. The download page can be provided through the network cloud disk, or the source code can be published on GitHub
2. There must be a block browser to facilitate all users to query relevant data information
in theory, these two methods can avoid the situation that people tamper with data without bottom line.
