Buddha's sermon in Ethereum

1. Ethereum, ETH for short. At the end of 2013, vitalik released the white paper of Ethereum, and in July 2014, the pre-sale of Ethereum began. At that time, insiders called this kind of token issue "crowdfunding". Through the 42 day pre-sale, the Ethereum team raised more than 30000 bitcoins through the pre-sale of 60102216 Ethernet coins; In addition, the early contributors who participated in the development before the pre-sale and the developers who have been engaged in project research for a long time are allocated according to 9.9% of the total amount of Ethernet coins sold at that time. So when Ethereum was officially released, there were more than 72 million Ethereum coins. After the end of Ethereum's pre-sale, it uses the proof of work mechanism POW for mining, and rewards the miners according to 26% of the total amount issued at that time every year. In October 2014, Ethereum reced the block output time from 60 seconds to 12 seconds, and now it is basically stable at 15 seconds, with 5 etheric coins awarded for each block
although the pow mining mechanism is adopted, the block out mechanism of Ethereum is different from that of bitcoin. Due to the short block time of Ethereum, Ethereum is easy to form isolated blocks. Isolated blocks refer to the blocks that are not on the longest chain. Bitcoin's isolated blocks have no block rewards, but in Ethereum, isolated blocks can be referenced. The referenced isolated blocks are called "Uncle blocks", and their packaged data will also be recorded in the blockchain. Unlike bitcoin, Ethereum's TERT block has a reward, and each TERT block can get a reward of 4.375 Ethernet coins at most
Ethereum is a programmable and Turing complete blockchain development platform, which is equivalent to a decentralized global computer. In a programming system, there are usually some virtual machines to compile and execute. Java has JVM. In Ethereum, there is also Ethereum's virtual machine EVM, which can execute any complex algorithm code. Developers can use existing programming languages such as JavaScript or Python to create their own applications on Ethereum. Through Ethereum's virtual machine, you can easily issue digital assets, write smart contracts, set up and run decentralized applications, and set up decentralized autonomous organizations
eth is also known as the internal fuel of Ethereum. Unlike currency digital assets, Ethereum is not only used for transfer, but also for payment of smart contracts
in order to prevent the Ethereum blockchain from being full of junk contracts and junk applications, and to establish and run smart contracts on Ethereum, you must use eth to pay for smart contracts. For example, when you transfer your newly created digital assets on the Ethereum blockchain, you need to use eth to pay the handling fee instead of your newly created digital assets.

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)

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 money

then 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

4. It depends on the difficulty of the algorithm and the current currency price. The income is not fixed!

5. First of all, understand what is an option

the so-called option is that investors trade a certain commodity, but they do not need to actually hold the commodity. They only need to pay a small transaction fee to the exchange to obtain the trading authority of the subject matter within a certain period of time, and they can trade in both directions
in terms of operation, if you are expected to be bullish, you will buy up and if you are expected to be bearish, you will buy down. The calculation of profit is the same as that of spot

to take a simple example, Xiaoming predicted that eth would rise sharply in the short term, so he spent 50usdt to buy 100 1-hour eth call options in the exchange, and one hour later eth rose 10usdt, then Xiaoming's profit was 100x10-50 = 950usdt
If Xiaoming bought the call options, and eth fell 10usdt in the reverse one hour later, Xiaoming's loss was only 50usdt of the call options, In addition, there is no need to bear the loss risk caused by the substantial fluctuation of spot and futures contracts

in short, the option is a kind of small and broad investment proct, only need to pay a little transaction fee, can obtain the right of proct return in a certain period, and the risk loss is only the transaction fee

at present, bitoffer adopts the American option trading method, which can grasp the market at any time without waiting for the closing time. It is easier to control the risk. If you have certain trading experience and market sensitivity, trading eth options is relatively simple.

6. I plan to start a series to talk about architecture. My previous experience is mainly in the area of Internet architecture. Recently, I am sorting out and analyzing the architecture of bitcoin, Ethereum and EOS, so I am going to write a series of articles to talk about the understanding of Internet architecture and blockchain architecture. It will be divided into four articles: 1. Internet proct architecture, 2. Bitcoin architecture analysis, 3. Ethereum architecture analysis, 4. EOS architecture analysis
there is no central server in Ethereum. Instead, there are many equal nodes connected by P2P protocol, which store all the data in many nodes. When a user initiates a transaction, the transaction will be broadcast out through P2P protocol. The miner node verifies, packages and further broadcasts the transaction to the whole network. After confirmation in the blockchain, the operation is considered to be unchangeable
in the articles on blockchain on the Internet, the two words distributed and decentralized are mentioned, sometimes slightly different, sometimes mixed. The author thinks that if we want to distinguish accurately, the distributed system emphasizes that multiple components work together by sending messages, and the decentralized system emphasizes that there is no central node to control the operation of the whole system. Therefore, we think that Ethereum is both decentralized and distributed, or running a decentralized program on a distributed platform.

7. A lot, but it will take a long time.

8. The essence of money is the general equivalent. It has the functions of value scale, circulation means, payment means, storage means and world currency. It is a certificate issued by the state or an organization authorized by the state for the distribution of goods in the whole society
it is different from the general equivalent: first, it is proced at different times; The general equivalent comes first and the currency comes second; Second, the general equivalent is not fixed in time, region and material quality, while the currency is fixed by gold and silver
money is a special commodity that acts as a general equivalent, a tool used as a medium of transaction, a storage value and a unit of account, and a material and symbolic appendage of people's commodity values. It includes not only currency in circulation, especially legal currency, but also all kinds of savings deposits. In the field of modern economy, only a small part of the field of currency is shown in the form of real currency, that is, the paper money or coins used in practice, and most transactions use cheques or electronic money. Currency area refers to the circulation and use of a single currency countries or regions
the essence of money at least includes the following aspects: first, money is issued by the state or institutions authorized by the state, which is the proct of the emergence of the state. Before the birth of the state, money can not be proced. Second, the scope of currency issuance is nationwide. Third, the object of money distribution is commodity (I use the concept of commodity here, and I emphasize here that only procts that realize exchange are commodities, and they are not commodities before they are exchanged with currency or other rights and interests.)
different currency areas need to introce the concept of exchange rate when they exchange currencies with each other. In modern economy, money plays a fundamental role. In macroeconomics, money is not only cash, but also cash plus a part of assets.

9. AEM is a counterfeit coin, far away from it
