Implementation of EOS Ethereum Technology

1. EOS is a blockchain development platform with strong scalability and support for large-scale commercial applications. First of all, EOS adopts dpos consensus algorithm and other technical means, and is expected to realize millions of transaction requests per second, which will be able to support thousands of commercial dapps. Ethereum is a public chain. Every application running on the Ethereum chain will consume the resources of the whole chain. However, EOS is just a blockchain infrastructure. Developers can freely create a public chain on EOS. The use of resources between chains will not be affected, and there will be no network congestion caused by the huge consumption of indivial application resources. Secondly, there is no need to consume EOS token to transfer and run smart contracts on EOS, which will attract more users

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

Course Overview

this course is for friends who are interested in the development of EOS decentralized application. The course covers the core concepts of EOS DAPP development, the development and deployment of smart contracts, and how the front page interacts with EOS blockchain. Finally, a complete DAPP development based on react and EOS is completed

Chapter 1: enter the world of EOS

Chapter 7: DAPP development of practical notes

comprehensively use EOS knowledge, use react to complete a decentralized application of EOS notes, and learn the complete process from requirement analysis to code implementation

The above course address is as follows: EOS tutorial

3. 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!

4. After the hard bifurcation of etc, ETH came into being. The relationship between the three currencies is just like that between yen, won and US dollar

5. 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.

6. 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

7. EOS is a typical representative of platform blockchain projects. What are its characteristics compared with Ethereum
EOS is a blockchain development platform with strong scalability and support for large-scale commercial applications
first of all, EOS adopts dpos consensus algorithm and other technical means, and is expected to realize millions of transaction requests per second, which will be able to support thousands of commercial dapps
Ethereum is a public chain. Every application running on the Ethereum chain will consume the resources of the whole chain, but EOS is just a blockchain infrastructure. Developers can freely create a public chain on EOS. The use of resources between chains will not affect each other, and there will be no network congestion caused by the huge consumption of indivial application resources
secondly, there is no need to consume EOS token to transfer and run smart contracts on EOS, which will attract more users
finally, when a system error occurs on the EOS, its "constitution" can be used to distinguish whether the error is indeed a bug and judge whether the community's repair measures are appropriate.

8. No, these three are not compatible with each other and each has its own purpose
choose your own direction
the cost of developing an interface is not so high. Except for EOS, there is not much data to be chained, which is basically completed locally. As a top blockchain technology developer in China, weisanyun is still a good technology developer.

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.
