Ethereum bitcoin side chain

3. Bitcoin and Ethereum are both digital currencies. Bitcoin ranks first in market value, followed by Ethereum. After registering with the bitnet exchange, you can invest in them.

4. Ethereum has established a programmable and Turing complete blockchain. On this blockchain, you can realize the proction of all kinds of digital assets through a simple program, and you can also accurately control the status of the blockchain assets circulating on Ethereum by writing a program, such as whether the asset is to be paid or locked or has a quota, whether the account is a treasure list or a white list Ethereum and other digital assets, etc. At the same time, Ethereum is a programmable, flexible and complete blockchain network foundation. On this basis, we can realize more functional procts of non regional fast chain assets. For example, I use Ethereum to set up smart contracts, which can be applied in personal daily economic life and enterprise economic activities. Ethereum is a new and open blockchain platform based on the concept of blockchain and blockchain assets. It allows anyone to build and run decentralized applications on the platform by using blockchain technology. In short, Ethereum technology is blockchain technology plus smart contract.

5. If you want to invest, it is recommended to consider whether you are optimistic about this instry first, because bitcoin, a kind of digital currency, has no real value, only collection value, and all the speculation prices are relatively high. If you want to invest, you should first choose a reliable old platform with good reputation, so that at least the money will not disappear out of thin air. You can take a look at AEX and fire coin, It has been more than 6 years and has a good reputation. For long-term investment, you can go to AEX for money management

6. Generally, blockchain, especially public chain, has main network and test network. The main network is a trusted blockchain network recognized by the blockchain community, and its transaction information is recognized by all members. Effective blocks will be added to the block ledger of the main network after the consensus of the blockchain network
many people don't understand what side chain is. This concept comes from bitcoin community and was put forward in December 2013. There are some problems with the birth of bitcoin itself or the mechanism of a blockchain itself. But if you modify bitcoin protocol or chain directly, it is easy to make mistakes. Moreover, because the bitcoin block has been operating continuously, if it is wrong, the amount of funds involved will be very large, which is not allowed
in fact, sidechains do not refer to a particular blockchain, but to all blockchains that comply with the side chain protocol. This term is relative to the main chain of bitcoin
for more information, what is a side chain

7. Hanging order is the number of orders waiting to be bought and sold behind the five trading prices transmitted from the exchange ring the market trading period. Together with five trading prices, these ten data constitute the most original public data in the whole trading system

8. Ethereum (ETH) is a "chain without separation", each application uses the main chain, and the structure of eth is similar to series connection. And aelf is to distinguish and reshape the structure between chains on the basis of eth. The solution of aelf is to change "series" to "parallel". The so-called "parallel" is a main chain, and then connect each branch chain on the N side. This is what the aelf team calls "mother union + n side chain Multi Chain" structure. Blockchain 3.0 project,? LF can realize the horizontal expansion of nodes through cluster or cloud + blockchain operation mode, continuously improve the overall performance of the network through benign competition, and become an important resource and infrastructure in the Internet era.
