Ethereum EOS Technology

1.

There are four different definitions of EOS, specifically as follows:

1, EOS: electronic and electrical

electrical over stress (EOS) is a common cause of damage to components, which is manifested by overpressure or over-current to proce a lot of heat, so that the internal temperature of components is too high to damage components (commonly known as burn out), It is a common way to damage electronic devices caused by pulse in electrical system

Embedded operating system (EOS) refers to the operating system used for embedded system. Embedded operating system is a kind of widely used system software, which usually includes hardware related underlying driver software, system kernel, device driver interface, communication protocol, graphical interface, standardized browser and so on

embedded operating system is responsible for the allocation of all software and hardware resources, task scheling, control and coordination of concurrent activities. It must reflect the characteristics of the system in which it is located and be able to achieve the functions required by the system by loading and unloading some moles

(3) EOS: Ethernet based on SDH

POS (packet over SDH) and EOS are two different ways to implement IP services in SDH network. POS technology appeared earlier, EOS appeared later, and some technical evolution has been made

The main difference between

and POS is that the Ethernet frame is encapsulated first, then mapped to the VC (virtual container) of SDH / SONET, and then the information is processed according to the cross mapping system of SDH

4, EOS: blockchain

EOS can be understood as enterprise operation system, which is a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture, which aims to extend the performance of distributed applications. Note that it is not a currency like bitcoin and Ethereum, but a token based on the EOS software project, known as blockchain 3.0

extended materials:

the characteristics of block chain (EOS)

1. EOS is a bit similar to Microsoft's windows platform. By creating a developer friendly underlying platform of block chain, it supports multiple applications to run 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

To put it simply, if you have an EOS, it 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. digital currency exchange "currency exchange"

development prospects

through a more in-depth understanding of EOS, EOS is quite valuable for investment. First of all, as the first to launch smart contracts, ETH runs smart contracts on eth, which is not free and depends on your gas. If gas runs out, the contract will stop. According to people who have used eth trading platform, it runs slowly and is very expensive, However, there is no such problem in EOS. The operation contract on EOS depends on the number of EOS you have. The more EOS you have, the more you can rent. With the continuous development, the more expensive the price will be; Secondly, it's very simple to develop DAPP on EOS, and you don't need to write many moles, because EOS itself builds the bottom mole for developers, which provides a platform and greatly reces the threshold of development; Thirdly, as an ordinary investor, owning EOS is equivalent to owning real estate, which can be used to rent and earn money. With the development of DAPP, the number of users increases, and the price increases irresistibly

EOS is a public chain system at the bottom of blockchain developed by block. One, which is specially designed to support decentralized application of Commerce, and its code is open source

bitcoin is called blockchain 1.0 because it opens up the world of digital cryptocurrency and takes a decisive step from 0 to 1

Ethereum is known as blockchain 2.0, because it provides Turing complete virtual machine that can run smart contracts, bringing unlimited possibilities

and EOS is called blockchain 3.0, why? Two words: performance

The positioning of EOS is the slogan of its home page:

English: the most powerful infrastructure for decentralized applications

Chinese: the most powerful decentralized application infrastructure

EOS expects to be an enhanced version of Ethereum, a high-throughput intelligent contract platform

although Ethereum has complete functions, it is limited by its design choice. Due to the block output speed of 15 seconds, the transaction throughput is far from large-scale practical level, which is only about 30 ~ 40tps (transaction / s). EOS, on the other hand, has chosen a different technology route, with the goal of achieving a considerable million TPS, which is quite attractive considering visa's actual processing speed of 1700tps

consensus mechanism of EOS

the reason why the throughput of bitcoin and Ethereum is so low is that they are constrained by the application scenario they envision and the consensus mechanism they choose for the scenario - both of them assume that the environment in which the system runs is totally untrustworthy, so they both adopt the consensus mechanism of proof of work

consensus, as the name suggests, is to reach a unified understanding of something - for blockchain, something refers to the confirmation of the transaction - any node to submit a transaction needs everyone's approval

the pow mechanism currently adopted by bitcoin and Ethereum is the design of the legendary Nakamoto Tsung. Under this mechanism, in order to obtain the bookkeeping right and digital currency reward, miners need to constantly dig for the compliant hash value, and confirm and package the transaction data through the consensus of hash value. POW has no access threshold, and any node has equal rights to participate in bookkeeping. Of course, the probability of winning is related to computing power:

the price of ram is based on Bancor algorithm, that is, it is regulated by market supply and demand: if the supply of ram exceeds the demand, more EOS certificates are needed to buy ram, At this time, more EOS certificates can be obtained by selling ram

memory is a consuming resource, which cannot be redeemed and can only be bought and sold. Take the issue of currency on EOS as an example. At present, the issue of currency requires 20m of memory. An EOS can buy 20KB. According to the current storage price, issuing a currency will consume 1000 EOS. This is the source of EOS memory consumption

4. BHT is now a kind of currency. It seems that there is a chemical name for the token name of a good exchange. What's the name? Forget it. It's too complicated!

5. EOS's vision is to become a public chain that can run a large number of commercial applications, and its core feature is "commercial"
in order to ensure decentralization and security, current public chain projects such as bitcoin and Ethereum have certain limitations in block scalability. Although the introction of Ethereum's smart contract has greatly enriched the application of blockchain, it also reces the threshold of issuing coins, making Ethereum's network very congested. Many existing public chains have the problems of slow network transfer speed, high cost, low concurrency or poor stability, which can not support the operation of real large-scale commercial applications
according to the white paper of EOS, EOS adopts the graphene block chain architecture, and the bft-dpos consensus mechanism reces the number of verification nodes, but makes the scalability of EOS significantly enhanced, and can support fast transaction processing speed. At present, bitcoin system can transfer about 7 times per second, while Ethereum can transfer 15 times per second; In contrast, EOS's white paper says it is expected to reach a million level TPS in the future
in addition, EOS provides a good development environment for users and developers. The transaction on EOS network does not need to charge service charge, which improves the user experience and makes it easier to attract users; EOS provides developers with a friendly underlying mole, which can support a variety of programming languages and rece the difficulty of DAPP development. Developers can focus more on the function implementation of the developed application.

6. Ethereum focuses on smart contract and Turing. EOS is based on blockchain operating system. Ethereum and EOS are two top blockchains. At present, there are bottlenecks in blockchain technology and narrow application fields.? LF cluster + cloud server is the most advanced blockchain 3.0 at present. Focusing on different blockchain projects such as public chain, storage chain, Im chain, asset chain and application chain, the advantage lies in resource isolation: each smart contract has its own blockchain, and the governance and development of proxy voting system of token holders has the most development prospect.

7. Eth is still the strongest public chain with the best comprehensive strength, and its popularity and investment risk are second only to bitcoin. EOS is better in performance, but there are many technical security defects, which do not prevent it from being one of the best public chains. I personally think that God V may be the first to realize the talent of technical prodigy. After all, ETH team has been developing, researching and making breakthroughs; BM has never been disappointing in terms of disappointment.

8. BTC, Eth and EOS are all digital currencies, and they are relatively stable and popular mainstream digital currencies at present. EOS is developed based on Ethereum algorithm, and the currency circle now generally believes that the price of EOS in the future will exceed eth. EOS has been running super node election for a while ago until now, so it has an independent market, and the rise and fall do not follow the trend of bitcoin. However, the market has weakened recently, so it is suggested to wait and see

The issue of EOS and Ethereum is a hot topic in the whole instry. Some support EOS and some support Ethereum

at present, although the main network of EOS has been online, it still needs to be improved in many places. At present, Ethereum is still in a dominant position

The Ethereum community of God V is not willing to be outdone to develop new technologies to change the shortcomings of Ethereum

therefore, whether Ethereum or EOS will win in the future, or whether a chain will surpass both, there is no definite number

for the questions about EOS and eth, you can see some opinions of the instry leaders (hundreds of celebrities talk about the "EOS" website link), and maybe you can find the answer

10. Coin an mining pool not only provides mining services, but also provides position rebate services. It allows miners to automatically switch the hash rate to mine the three most profitable supporting coins based on SHA-256 algorithm - bitcoin (BTC), bitcoin cash (BCH) or bitcoin Sv (BSV). This new function can increase the average income of users using this function by 1%. Help miners make more money.
