1. what is Ethereum:
Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. blockchain technology is one of them
Ethereum platform can safely run any program users want
advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum
what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application
The design of Ethereum is very flexible and adaptable
Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields
blockchain applications of Ethereum
Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc
Ethereum has achieved more than 100 blockchain applications by many start-ups
Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged
the relationship between Ethereum and blockchain:
Ethereum is a programmable blockchain
Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes
in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency
like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"
2. Ethereum blockchain has exposed three major problems, and its founder vitalik buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied 20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of 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. 99% of them are deceiving. It's deceiving to say how much it will appreciate. It's just a technology, its application is valuable.
5. This is two different concepts. According to different standards, blockchain can be classified into three categories:
& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain
&# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain
&# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain
the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process
6. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"
that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved
most of the existing public chain projects in the market are difficult to put into use on a large scale
7. I'm very responsible to tell you that blockchain is definitely not a scam. First of all, the most talked about blockchain is digital currency. Here I want to state that there is no digital currency out at present. As you know, bitcoin, Ethereum, reborn, etc. are all digital encryption codes, and they don't have full purchasing power. At present, they are only in the stage of speculation. Blockchain is widely used in the future It will certainly overturn the existing economic model and affect the way of human life. Compared with the Internet, it will have a qualitative leap. Loser poor want to become a billionaire. This is the best shortcut. If you want to know more, you can continue to ask questions
8. Ethereum is a low-level system that can realize intelligent contract and open source on the blockchain. At present, the biggest development problem of Ethereum is that all applications use the main chain, which leads to the main chain not being separated and blocking seriously. The mission of aelf (ELF) is to solve it,? LF emphasizes the pure decentralized network, the side chain and the main chain can flow, and the asset side chain is connected to the main chain. It focuses on the "n-side", because it turns the planar blockchain structure into a three-dimensional multi-dimensional structure. It can divert the block trading volume to the greatest extent. Therefore, problems like "blocking" or even "paralyzing" existing in Ethereum will not appear on aelf. This is also the reason why elf token will double in two weeks, indicating the development direction of the next regional chain technology.
9. Don't say ether, even when big pie trading, there are risks. If you want to rece the risk, you need to find a reliable platform and a reliable team, so as to minimize the risk.
10. Undoubtedly, usdt was born with a halo. The second half of 2017 was a disaster for the coin circle, but it was an opportunity for usdt. With its unique stability advantage, it quickly took on the link between the legal coin and the token, and was recognized by the major exchanges and the majority of leeks, becoming the stable coin recognized by the coin circle. However, with the continuous issuance of usdt, there are more and more doubts about usdt. "Stable currency is not stable" and "coin circle printing machine" have become the new labels of usdt. Coupled with the investigation and supervision of the US government on tether, the trust crisis of usdt is becoming more and more serious. This time, it is reported that CNH has been resisted by many bigwigs in the coin circle, and there are few voices of support. Although usdt faces many doubts, I don't think the current position of usdt in the currency circle will have a great impact in a short period of time, let alone a crash. Unless the U.S. government makes a drastic cut, this is unlikely.
