Ethereum shares

1. Hello, it's called EOS token. It's based on Ethereum token
EOS 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.

2. Since its establishment, Beijing Digital Capital Technology Co., Ltd. has been committed to studying how to effectively solve the instry pain point of "traditional instry + blockchain". Various projects emerge in endlessly in the blockchain instry, and the technology has been innovated repeatedly. At present, the hottest topic is "stable currency". Beijing digital technology has also been supporting the stable currency system, bringing new development opportunities for the blockchain instry
what is stable currency
stable currency, as its name suggests, is a cryptocurrency with stable value, and its exchange ratio with legal currency remains relatively stable. Because the exchange ratio between legal currency and goods and services is relatively stable, the ultimate anchor of stable currency is goods and services, that is, the actual purchasing power
stable currency originated from usdt (benchmarked US dollar) issued by 2014 bitfinex established tether limited. The opportunity for the birth of cryptocurrency is that the mainstream currency accounts for the vast majority of the market value, but the price fluctuates violently, which makes the liquidity of cryptocurrency market decline. In this case, in order to protect their assets, investors need to find a better way to store value, so the stable currency market arises at the historic moment
the essence of stable currency is a kind of accounting voucher
modern banking system is based on the central bank at the bottom, commercial banks at the top and financial technology companies at the top. Their basic prototype mainly comes from the double entry bookkeeping which was born 500 years ago. Even after so many years, the banking system is constantly developing and changing, but its core is the centralized account system, which depends on the central bank. When we transfer money from one account to another, we are actually making account changes through the bank. When using stable currency for transfer and remittance, it completely transfers from its own account book to another account book. The essence of stable currency is a kind of bookkeeping voucher
some people would say, isn't Alipay also using block chaining technology? On this basis, Alipay upgraded and upgraded the account book, which is two different schemes based on the stable currency issued by block chain technology. You see that money is transferred from a Alipay account to another Alipay account, but it is still operated in the central bank's account system.
why is stable currency the future of blockchain
at present, stable currency is mainly used to provide channels for legal currency to enter the cryptocurrency world, help currency people avoid risks in transactions, and provide payment services for blockchain application projects. Although the current digital currency market is not too optimistic, but the cryptocurrency project is in constant development. The number of stable currencies on the market has already exceeded 50, and is still on the rise. 2019 is bound to be the year of stable currency outbreak. How did stable currency break through in the wave of digital currency? Why is stable currency the future of blockchain? This involves how stable currency affects the blockchain instry
tickets for users to enter the market
after "94" in 2017, China banned the market circulation of cryptocurrency, restricted banks and other financial institutions as payment platforms or channels, and many countries also restricted the circulation of cryptocurrency. But there are still a lot of users who want to enter the market, they will choose over-the-counter trading and trade through the community. But because of the uncertainty, opacity, small scale and other problems, OTC has some trading risks. Usdt, a stable currency anchored to the US dollar at a ratio of 1:1, has become a supplementary scheme for some new funds
the insurance medium of user assets
in the weak market, the price of token fluctuates greatly, and traders do not want to take risks or leave the market. In the case that the trading platform does not support legal currency trading pairs, it is almost the only choice to use "stable currency trading pairs" to exchange for stable currency
the emergence of stable currency is the proct of a special historical stage e to the contradiction between the rapidly developing demand for token investment and the restriction of legal currency admission by regulation. The more serious the price fluctuation of mainstream currency is, the more valuable the existence of stable currency is
"trade as settlement" is an efficient payment and settlement tool
blockchain technology has great value in the field of payment and settlement. With the emergence of JPMorgan JMP, many banks around the world have begun to explore how to use blockchain technology to issue stable currency. The "stable currency" issued by these banking giants is essentially using a convenient and efficient settlement network based on blockchain technology. The more financial institutions and customer groups join the network, the greater the value of the settlement network
as JPMorgan Chase, IBM and Facebook have revealed that they want to issue currency, stable currency has once again set off an upsurge. After the strong fluctuation of usdt in the second half of 2018, it was derided as "unstable stable currency" by many people, so Pax, tusd, GUSD, etc. followed closely. Seizing the market quota of stable currency is very fierce for a time, but the fierce market competition means that there is not much space left in the market, and no matter how much stable currency there is, it seems meaningless. Then the major exchanges began to launch their own platform currency. JPMorgan Chase, IBM and Facebook also entered the market. The situation of stable currency also changed greatly. Facebook and JPMorgan have both broad user base and far-reaching economic impact, and issuing currency will certainly have inherent advantages. Beijing Digital capital technology, which is deeply engaged in the study of the significance of stable currency, has made practical application of stable currency in postal, supply chain finance, lottery and other fields. It is understood that the world's first African blockchain lottery will also be released in the near future. In this way, we can certainly expect to stabilize the currency market.

EOS is owned by an organization called block.one, but most people contact EOS by Daniel Larimer (BM), a software developer who has been involved in other blockchain projects, including bitshares and steemit, a distributed social network. The CEO is Brendan Blumer, a serial entrepreneur

EOS is considered as Ethereum for large enterprises

EOS public chain allows people to build decentralized applications (dapps) on it and run these applications

according to the developers, the difference between EOS and Ethereum is that EOS solves the performance shortage and availability problems encountered by developers when using Ethereum. There are other small differences that we will discuss below

{rrrrrrr}

extended data:

generation of EOS:

unlike bitcoin, EOS is not obtained by mining. Bitcoin's consensus protocol, known as workload proof, uses a lot of power and can only handle limited transactions

On the contrary, EOS allocated 1 billion EOS tokens in one year's ICO. After that, EOS uses a consensus protocol called certificate of entitlement (dpos) to create the blocks that make up the blockchain

in this system, the community votes for the witness who is responsible for verifying the transaction. If the witness misbehaves, the community members can also vote, and others will take their place

The main features of EOS are as follows:

1. EOS is a bit similar to Microsoft's windows platform. By creating a developer friendly underlying platform of blockchain, it supports multiple applications running at the same time and provides the underlying template for the development of DAPP

EOS solves the problems of delay and data throughput by means of parallel chain and dpos. EOS can process thousands of data per second, while bitcoin has about 7 transactions per second, and Ethereum has 30-40 transactions per second

There is no service charge for EOS, and the general audience is more extensive. The network and computing resources needed to develop DAPP on EOS are allocated according to the proportion of EOS owned by developers

when you have EOS, it is equivalent to having computer resources. With the development of DAPP, you can lease your EOS to others. From this point alone, EOS has a wide range of value. In short, having EOS is equivalent to having a set of rent to collect rent for others, or having a piece of land to rent for others to build a house

at present, the vast majority of digital currency transactions are concted in exchanges. Among the numerous exchanges, bitfinex, binance, okex and so on are well-known

However, bitcoin and other digital currencies, as decentralized assets, have to be traded in a centralized exchange, which seems to have hidden contradictions and dangers

1. Problems and challenges of stock exchanges=“ //www.yuanxue365.com/en/img_fd039245d688d43fdf16c83b761ed21b0ff43bbf ">

in February 2014, Mt. GOx, the world's largest bitcoin exchange at that time, was stolen 850000 bitcoins, and the price of bitcoin suffered a" cliff "crash on that day. Later, it was revealed that Mt. GOx was in fact a thief, and only 7000 bitcoins were actually stolen

in August 2016, bitfinex, the largest U.S. dollar bitcoin trading platform, suffered a security vulnerability, resulting in the theft of 120000 bitcoins, which was worth $65 million at that time. If converted into the price in December 2017, it would be worth nearly $2 billion

on December 19, 2017, South Korea's youbit exchange was attacked by hackers and lost 4000 bitcoins, and the exchange declared bankruptcy

on December 21, 2017, the Ukrainian liqui exchange was stolen 60000 bitcoins, and the unit price of bitcoin plummeted by US $2000

in 2018, such a drama will only continue

in addition to the threat of hackers, traditional exchanges also have some inherent shortcomings, such as lack of supervision and inefficiency. The security of the exchange for investors can only rely on its own credit, and the cost of running is very low. The stock exchange is regulated at the national level, but there is no such sword of Damocles on the top of the digital currency exchange. Moreover, in an exchange, the same order can only be submitted to one exchange. After the user places an order, the funds used for the transaction will be frozen and can only wait for the completion or cancellation of the transaction. These are undoubtedly inefficient

All in all, the problems of exchanges are the problems of centralization

2. Decentralization of exchanges=“ //www.yuanxue365.com/en/img_86d6277f9e2f070889a173c9e224b899a801f257 ">

(1) the progress of the exchange itself

the upgrade of security means is various. At present, the best use is cold wallet, that is, to keep the digital currency in the offline U disk. At the end of 2017, when the YouTube exchange was attacked, 75% of its assets were withdrawn into the cold purse in time to avoid greater losses. However, it seems to be a helpless way to protect the online assets by offline means. Of course, there should be many other methods, which will not be repeated here

(2) the representative of cross ledger transaction is ripple network, and the operating company is ripple labs, which is a semi centralized system. Ripple is a decentralized clearing agreement. In order to solve the high cost and delay of inter-bank clearing, its base currency is XRP. Ripple network can connect all kinds of assets, such as US dollar, RMB, Japanese yen, bitcoin, etc. to its own network. In this system, U.S. dollars or bitcoin can be converted into reborn currency, and then reborn currency can circulate freely in the network, just as a highway is built between various assets. Due to the support of major banking institutions, the reborn currency achieved nearly 300 times growth in 2017

(3) decentralized exchange

some teams try to use blockchain technology to build a decentralized exchange. This kind of decentralized exchange, to some extent, is an extension of cross ledger trading

bitshares is the most representative of early rising projects. It builds a blockchain development platform with servers scattered all over the world. Even if some of them are attacked, the system will not collapse. Anyone can transfer money and borrow money freely on this platform, and can also quickly build a centralized exchange based on this platform. In order to ensure stable value, bitstocks also require three times of digital assets as collateral. At present, bitstocks are running fairly well

later, with the development of Ethereum and smart contract, the x x protocol came into being. This is an open protocol running in the Ethereum blockchain and a decentralized exchange in the Ethereum ecosystem. The agreement has attracted many investors. At present, it has completed financing and started to build open source software tools and infrastructure. Of course, there are many competitors. Ether Delta, IDEX and oasis DEX are trying to provide similar functions. Moreover, it is a smart contract system based on Ethereum, which only supports erc20 token. If other smart contract public chains start to rise, the demand will be reced

in addition, there are some teams that are entering, such as the domestic road seal agreement, looping (LRC) in English. They adopted a design similar to the X protocol, and also introced a fast payment function similar to the lightning network. It is characterized by trying to match multiple exchanges, the user's order can be broadcast to multiple exchanges, and completed by different exchanges. Moreover, the user can still use the account funds after placing an order, and the user's behavior of transferring part or all of the funds is equivalent to partial or total cancellation. To some extent, it improves the breadth and timeliness of the transaction. However, this system seems to have damaged the "power" of the existing exchanges. Whether we can persuade everyone to play together will be a difficult problem

At present, there is still a long way to go for the construction of decentralized exchange. In 3-5 years, traditional exchange will still be the main battlefield of digital currency

However, in the future, it is worth looking forward to let the decentralized digital currency get rid of the shackles of centralization

Bitcoin's business model is skyrocketing, and now there are many procts of this economic system

statement: we don't recommend any currency here. We only briefly introce some mainstream blockchain projects with innovative value, and share simple comments

bitshares / BTS: after bitcoin, it is the first batch of decentralized autonomous systems based on dpos, new code and oriented to real subdivision. It has surpassed bitcoin and Ethereum to become the most active decentralized system. The daily transaction volume exceeds 85W, with an average of 9.83 transactions per second. As a result, it has been discovered by the market and increased by 50 times

Ethereum / eth: its market value is second only to bitcoin, about 60% of bitcoin's market value. Ethereum's business logic itself has no problem. At the beginning, the valuation of ICO was close to 500 million RMB, and now it has increased nearly 1000 times (the cost of the first batch of people is about 2-5 yuan)

Zec: compared with bitcoin and Ethereum, the risk of z-coin will be greater, and its value will take a longer time to reflect. But in the long run, the value of anonymity will be one of the values that human beings generally pursue

6.

The CentOS network card cannot be connected to the Internet. The ethtool displays link detected: no speed: unknown! Duplex: Unknown! ( The solution is:

1. Edit the virtual machine

7. Will not rece, your combat acquisition proficiency and so on, no matter how you will not rece, I do not like this game, from the beginning of the internal test, I began to play, no money to die

8. First of all, it adopts the technical architecture of parent chain child chain, which puts the transaction in the child chain processing, and supports the cross chain between the child chains, so as to provide a good underlying architecture for the high concurrent transaction of subsequent assets, without congestion like bitcoin and Ethereum. Secondly, the token on the chain has its own protocol. According to the requirements of different countries and regions, the corresponding intelligent protocol stack is opened to realize the legal compliance of the token in the transaction.

9. Kucoinshares, or "KCs" for short, is the exchange token promoted by the kucoinblockchain asset trading platform. KCs coin is a decentralized blockchain asset issued by Ethereum. It is the erc20 standard token based on Ethereum blockchain.
