bitcoin, lightcoin, Ethereum, a smart contract platform, and decent, a distributed content publishing platform, all use blockchain technology.
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"
BTC, usdt, ETH, BCH, LTC mean respectively:
1, BTC
bitcoin. The concept was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software is designed and released, and the P2P network is built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
2, usdt
TEDA currency is a virtual currency that links cryptocurrency with legal currency US dollar, and is a virtual currency kept in foreign exchange reserve account and supported by legal currency
EthEthereum is an open source public blockchain platform with intelligent contract function, which provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether
4. BCH
bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers
at 20:20 on August 1, 2017, bitcoin cash starts mining, and each bitcoin investor's account will have the same amount of bitcoin cash (BCH)
5, LTC
litecoin, abbreviated as LTC, currency symbol: & # 321;; It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum")
The token on theblockchain is called ether, and the code is eth. It can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum
the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, with the general meaning of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin
extended data:
Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks
for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound
in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale
Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum. The concept of Ethereum was first inspired by bitcoin by vitalik buterin, a programmer, between 2013 and 2014, and now it's 2.0. Ethereum 2.0 is also something that the whole coin circle is waiting for. In order to celebrate the birth of the genesis block of eth2.0 on December 1, chinacoin officially supports the exchange of eth2.0 verification nodes at 17:00 Hong Kong time on November 20, 2020. It will invest its own eth in the verification node mining and exchange qeth to obtain liquidity. It will participate in the mining as soon as the exchange is received. Now it will give back to the user's welfare. The top 1000 eth enjoy the over exchange of qeth according to the ratio of 1:1.02. Compared with eth2.0, qeth has too many advantages: liquidity is guaranteed, users do not need to bear the technical cost, the threshold of participation does not need 32 eth, as low as 0.1eth, nodes are maintained by the platform, and the revenue is distributed according to eth2.0< br /> < br /> < br />
etc (Ethereum Classic) is a bifurcated currency that Ethereum hard bifurcates after 1920000 blocks, and its function is very similar to Ethereum. Etc adheres to the concept of decentralization and supports the consensus mechanism of blockchain guarantee. Etc firmly believes that once the blockchain starts to run, its development direction will not be controlled by any central team, but will be determined by the consensus of the people participating in the whole network and the consensus of the computing power of the whole network
the Ethereum blockchain hard branching in July 2016 aims to transfer the Dao funds stolen by hackers to an account controlled by investors, and let the old transaction records be forgotten by history. Most Ethereum developers are involved in the reversal, as are exchanges, startups and other members of the ecosystem. A few days later, the project returned to normal. But not everyone wants to forget the old record. As a result, a small number of miners continued to use the original blockchain as a protest. They described the hard fork as a capital withdrawal for the abandoned project of the Dao. So Ethereum classic (etc) was born

First of all, we need to understand what is MLM:
MLM refers to the illegal behavior of organizers and development personnel to obtain wealth by calculating and paying remuneration to the developed personnel based on the number or performance of the personnel directly or indirectly developed, or requiring the developed personnel to pay certain fees to obtain the qualification to join. The essence of MLM is "Ponzi scheme", that is to say, the money of later comers is distributed to the income of former comers
However, the new type of MLM does not restrict personal freedom, does not accept ID cards and mobile phones, and does not take classes collectively. Instead, it uses capital operation as a banner to pull people to cheat money, drives luxury cars, wears gold and silver, and uses money to attract your relatives and friends to join in, and finally makes you lose all your moneythen judge whether the ether coin is a kind of MLM, whether you need membership fee, whether you need to ask your relatives and friends to join
extended materials:
Ethereum is an underlying technology platform on which developers can create distributed applications. With the application, there will be transactions. With a transaction, you need money to complete the transaction. In this way, money has value, and investors' investment has a return. If the transaction volume on the platform is larger and larger, the demand for money will be higher and higher, and the money will be more and more valuable
from the perspective of image, bitcoin creates a kind of digital gold, while Ethereum creates a country, and Ethereum is the credit currency of the country
after bitcoin, there are thousands of digital virtual currencies in the world, many of which are completely deceptive in the guise of "digital currency". Previously, Haikou Municipal Public Security cracked down on a pyramid selling organization called "Eurasian currency", which operated on the internet pyramid selling platform, making more than 40000 investors cheated, involving 4.06 billion yuan. The field of virtual currency has just started, so we need to be cautious

Ethereum uses fog computing. The data processing and applications of fog computing are concentrated in the devices at the edge of the network, rather than almost all stored in the cloud, which is an extension concept of cloud computing, which is more in line with the spirit of decentralization of blockchain. If all the storage and operations still stay on the centralized server, then it will not be a real blockchain
recently, the hot "ethereal cat" on Ethereum network has led to the congestion of Ethereum network. The problem is that the TPS concurrency per second of Ethereum is too low. The emergence of ethereumfog with fog computing will break the embarrassing situation of Ethereum network congestion, and add powerful decentralized storage and additional computing power to the chain.
