How large system capacity can Ethereum carry

1. Ethereum is a new and open blockchain platform, which allows anyone to build and use decentralized applications running through blockchain technology in the platform
just like bitcoin, Ethereum is neither controlled nor owned by anyone - it is an open source project created by many people around the world. Different from bitcoin protocol, Ethereum's design is very flexible and adaptable. It is very easy to create new applications on the Ethereum platform. With the release of homestead, anyone can use the applications on this platform safely
Ethereum is a programmable blockchain. It does not give users a series of preset operations, but allows users to create complex operations according to their own wishes. In this way, it can be used as a platform for many types of decentralized blockchain applications
in a narrow sense, Ethereum refers to a series of protocols that define a decentralized application platform. The core of Ethereum is Ethereum virtual machine (EVM), which can encode any complex algorithm. In computer science terminology, Ethereum is "Turing complete.". Developers can use the existing JavaScript and python as the model of other friendly programming languages to create applications running on the Ethereum simulator.

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)

3. Ethereum project draws lessons from the technology of bitcoin blockchain and expands its application scope. If bitcoin is a special calculator using blockchain technology, Ethereum is a general-purpose computer using blockchain technology. In short, Ethereum = blockchain + smart contract
compared with bitcoin, the biggest difference of Ethereum is that it can support a more powerful scripting language (technically speaking, Turing's complete scripting language), allowing developers to develop any application and implement any smart contract on it, which is also the most powerful point of Ethereum. As a platform, Ethereum can be compared with Apple's app store, on which any developer can develop applications and sell them to users. Each type of financial contract can be written as a smart contract in the form of program code<

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

4. The network will be upgraded to Constantinople & Petersburg at block height of 7280000. L, Z, b show that it will be upgraded on March 1, 2019 Beijing time. I don't know if the upgrade is successful

5. Xu Mingxing, He Yi and Zhao CHANGPENG<

Xu Mingxing: founder of okcoin, technical otaku, and now CEO of the company

He Yi: former host of a tourism channel, later joined okcoin, mainly responsible for participating in some instry activities and promotion activities, and now is the vice CEO of the company<

Zhao CHANGPENG: he used to be the head of blockchain China, a world-famous online wallet. Later, he moved to okcoin, mainly responsible for the development of platform technology and projects

this is the legendary bitcoin tiantuan of okcoin

in the bitcoin mining instry, Zhang Nangeng is the founder of Avalon. It is his mining machine that has completely subverted the bitcoin mining instry and is currently deploying large-scale mines.

6. Generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
IBM loves it because it sees the potential of blockchain. Blockchain is popular all over the world. Bitcoin, Ethereum and decent are all connected with bitcoin.

7. There are two ways. One is the overall command of the whole legion, click execute. The computer will direct your Legion to attack automatically and advance to your designated line
overall command defense, one is specific to the specific command of each division. The first is convenient, but sometimes the computer will be stupid. The defense is simpler. The attack in iron and steel ambition 4 is to let the troops go to the enemy's identity, and the attack will take place in the enemy's territory. Stay in your own identity, and the other party's troops will come to your province, then draw a line with the Legion's command (it must be the front line with the enemy), and then advance on the point line, and draw a line where you want to advance after the attack, You choose the Legion. Each has its own advantages and disadvantages. The means of commanding attack and defense are different because of these two ways; The second kind of command is more desirable, but it has a large amount of operation. Attacking an opponent from multiple directions has a combat efficiency bonus, and the probability of winning will be increased. Right click the province you want to attack, and just don't move. The existing troops in the attacked province will defend automatically

generally speaking, it will take place in your province

to command the attack as a whole, you need to select the Legion first, and use the Legion's command to select the defensive line of retreat. After delimitation, the Legion will automatically perform the task of defending this line

for manual attack, you need to select one or more troops

8. Hard attack is "damage to armor". It can't damage personnel. Similarly, soft attack can't damage armor
