Ethereum ID
bitcoin is a digital currency designed by Nakamoto in 2009. The identity of its founder "Nakamoto" has always been a mystery. Rumors about "father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura. Matcha exchange can find out more about Ethereum bitcoin
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

It does not belong to MLM
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 proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform", and began to develop through crowdfunding in 2014. The market value of Ethernet currency is second only to bitcoin, and it is the second largest encrypted digital currency in the world
extended data
bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years. In fact, bitcoin's blockchain is a set of distributed database. If a symbol bitcoin is added into it and a set of protocol is specified, the symbol can be transferred safely on the database without trusting a third party. The combination of these features perfectly constructs a currency transmission system bitcoin network
however, bitcoin is not perfect, and the scalability of the protocol is a deficiency. For example, there is only one symbol in the bitcoin Network - bitcoin, and users can't customize other symbols. These symbols can represent the company's stocks or debt certificates, which will lose some functions
In addition, a stack based scripting language is used in bitcoin protocol. Although this language has some flexibility to realize functions such as multi signature, it is not enough to build more advanced applications, such as decentralized exchanges. Ethereum is designed to solve the problem of insufficient scalability of bitcoinEOS coin
EOS (Chinese Name: EOS, English Name: EOS, abbreviation: EOS) is a token based on Ethereum released for eos.io blockchain system. Blockone is a new blockchain architecture developed by blockone company, which aims to expand the performance of distributed applications. The goal of EOS project is to achieve a blockchain architecture similar to the operating system supporting applications. The architecture can provide account, identity authentication, database, asynchronous communication and program scheling on hundreds of CPUs or clusters. The ultimate form of this technology is a blockchain architecture, which can support millions of transactions per second, and ordinary users do not need to pay for the use of the blockchain
function of EOS token
the current form of EOS cryptocurrency belongs to ERC 20 smart contract token on Ethereum blockchain. EOS ERC 20 token will be converted into the cryptocurrency available in EOS system 1:1 after the formal launch of EOS blockchain. The EOS system is expected to release the test network in August 2017, and it is expected to take one year for the main network of EOS blockchain to go online. The following application scenarios are introced after the EOS blockchain is officially launched
EOS cryptography currency has three main application scenarios: bandwidth and log storage (hard disk); Calculation and calculation reserve (CPU); State memory (RAM)
both instantaneous and long-term components consume bandwidth and computation. The blockchain system will maintain logs of all messages, which will be downloaded and stored by all complete nodes. With log information, the state of all applications can be reconstructed
the specific application scenario of EOS cryptography currency can be explained as:
receiver payment: customers purchase specific procts from the business, and the sales revenue of these procts will be used to pay the business cost, so as to avoid customers paying for the use of blockchain directly, and will not restrict or prevent enterprises from determining the monetization strategy of their procts
authorization capability: if a blockchain is developed by using EOS software system and its token is held by a ticket holder, it may not need to consume all or part of the available bandwidth immediately. Such a holder can choose to give or rent the unused bandwidth to others
separate transaction costs from token value: if the application owner holds a corresponding amount of tokens, the application can continue to run in a fixed state and bandwidth usage. Developers and users are not affected by price fluctuations in the token market, so they are not price dependent
block reward: each time a block is generated, the eos.io system will reward the block generator with a new token. The system may be configured to limit the reward cap for block procers, so that the total annual increase in token supply does not exceed 5%
community welfare applications: users can choose three community welfare applications, also known as smart contracts. These smart contracts will collect tokens based on the proportion of votes each application receives from the token holder. The elected application or smart contract can be replaced by the smart contract of the newly elected application or token holder
What are the technical advantages of EOS
1. EOS creates a developer friendly underlying platform of blockchain, which is similar to the operating system of blockchain. It has powerful performance, can support multiple applications running at the same time, and can support multiple programming languages at the same time. It provides developers with underlying moles to lower the development threshold, just like Microsoft's windows. Do you think Microsoft is worth money
2. EOS solves the problems of delay and data throughput through parallel chain and dpos. EOS can achieve a processing capacity of one million per second. At present, bitcoin has 7 transactions per second, while Ethereum has 30-40 transactions. This super power of EOS can hang bitcoin and Ethereum. For example, the recent cryptokitties | collect and breed digital cats! This is a very popular eth game. Only one game accounts for about 15% of eth's throughput. If there are seven or eight similar games at the same time, ETH will die. It's scary to think about it. Eth, which can't expand bandwidth, will have great challenges in throughput, and EOS can solve the above problems.
new type of MLM: no restrictions on personal freedom, no ID cards and mobile phones, no collective classes, but to use capital operation as a banner to pull people to cheat money, drive luxury cars, wear gold and silver, etc., attract your relatives and friends with money, and finally make you lose your money
you should be careful when paying dividends at all levels, 100% of them are
Q, someone has analyzed you.
in front of the article: the video version is slightly different from the text version. If you want to see my affectionate interpretation, please see the video version (meow understands blockchain phase 22 | sharding: Ethereum is too slow, "disk" him!), The logic of thinking is strange. Please see the extended version
recently, Ethereum has shown an overwhelming positive trend e to the Constantinople upgrade, while Ethereum's upgrade road is like upgrading and fighting monsters, falling into rabbithole. No one knows how deep the hole is. Since it is a long way to go, it is of vital importance to make every step well and accurately. After overcoming this difficulty, Ethereum's next technical difficulty, sharding fragmentation, has been put on the table again. This issue of "meow understands blockchain" will take you into sharding, the magic weapon that makes Ethereum fast
what is sharding
slicing technology is not a new concept. At first, it is an optimization scheme for large central database. Specifically, it divides the data in large database into many shards according to certain rules, and then stores these data in different servers to rece the data access pressure of each server, So as to improve the performance of the whole database system
let's take a small popular example:
for example, meituan, Didi taxi and other software that we often use can be divided according to the "city". Because the data of different cities do not need to communicate, the data of different cities can be stored in different databases, so that the database server can be deployed to the nearest node from the corresponding city, Can also improve the speed of access, why not do it
from the above examples, we should have a preliminary understanding of the concept of fragmentation. What about fragmentation in blockchain scenarios
taking Ethereum fragmentation as an example, in the original single chain system, the overall performance of the public chain depends on the performance of a single node. After fragmentation, each node only needs to undertake the work of the whole network, and each fragmentation works in parallel. According to vitalik, each shard is like a separate galaxy, and each fragmentation is like an independent universe, In this way, the efficiency will be improved naturally! Originally, the total network TPS of Ethereum chain was about 20. Now, if it is increased to 100 pieces, the total network TPS can be increased to 2000. Similarly, the total network capacity will be increased to 100 times of the original
"each node only needs to undertake part of the work of the whole network", which will lead to several major problems. 1. How to determine which piece of work this node is responsible for? 2. Which transactions should be classified into which segments? 3. Does each node only need to store its own transaction information (ledger)
according to the implementation of the above problems, we can divide the fragmentation into three types: network fragmentation, transaction fragmentation and state fragmentation
Network fragmentation: how to divide the nodes of the whole network into different partitions
transaction segmentation: how to divide the whole network transactions into different segments
State fragmentation: how to make each node only maintain the account book in its own fragmentation without affecting the security of the whole system
the difference and connection between main chain and fragmentation chain
we have understood the types of fragmentation, so what's the difference between main chain and shard chain
turn left | turn right
the realization of Ethereum fragmentation is a long process. Even vitalik himself said that it will be graally realized by stages. We'd better look forward to whether fragmentation can move from theory to practice

I hope I can help you, isn't it hard to find a way to adopt it?
