The meaning of each domain in Ethereum block

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. Based on the core idea of bitcoin network, Ethereum project puts forward many innovative technical concepts, including smart contract, account based transaction, Ethereum and fuel.

what is Ethereum:

Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. Blockchain technology is one of them
Ethereum platform can safely run any program users want

advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum

what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application

The design of Ethereum is very flexible and adaptable

Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields

blockchain applications of Ethereum

Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc

Ethereum has achieved more than 100 blockchain applications by many start-ups

Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged

the relationship between Ethereum and blockchain:

Ethereum is a programmable blockchain

Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes

in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency

like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"

BTC bitcoin

bitcoin is the first distributed digital asset platform created. Since its launch in 2009, it has proven to be not only the most popular, but also the largest market capital value. In addition, it is also the most expensive, with a value of $10710 per coin on February 17, 2018. Bitcoin introces the first blockchain distributed ledger dedicated to recording all transactions, and gets rid of the function that users need a central authority to process or verify transactions

its goal is to provide a platform for users to conct cross-border transactions without any intermediary, which is what we call decentralization. The platform's largest money (BTC) supply is about 21 million. Of this figure, about 16.5 million have been mined and are now in circulation. It is mined all the time around the world to ensure the circulation of coins

Advantages:

1. Its distributed system provides users with great freedom

2. High portability

This is a secure network

disadvantages:

1

2. The user may lose the key

eth Ethereum

Ethereum is also a distributed platform, which was created by Network Programmer vitalik buterin in July 2015. Ethereum aims to enable users to create and deploy smart contracts. One of the main functions of smart contracts is to allow the creation of encrypted assets or tokens running on Ethereum networks. Ethereum token is used to purchase various functions such as cloud storage space. These tokens are stored in a digital wallet compatible with Ethereum blockchain

Ethereum's digital currency ether serves as the medium for executing smart contracts. At present, about 98 million ether coins have been mined and circulated, and the circulation supply increases by about 18 million every year. Ethernet coin is created to run on the Ethereum network. It can be used to compensate the participant nodes or transfer from one user to another

advantages:

1

2

The safety was very high

disadvantages: large circulation

< H2 > extended data:

generation principle:

starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique

in the metaphor of banknotes, bitcoin is the number of the top word of a banknote. The number of the top word on a banknote owns the banknote. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start

after completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to post the address to others, and you can pay through the same client

after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

6. Ethereum is not a kind of currency, but a decentralized intelligent protocol. It can be understood as a huge global account book. The logic of this intelligent protocol does not need a specific server to support its daily operation. Instead, it is the protocol terms given by the executors before entering among the scattered users. This is an application evolved from decentralization
compared with bitcoin, we can find that Ethereum is more difficult to develop a new encryption technology than bitcoin. This breakthrough has greatly reced the development cost and time for developers who apply blockchain technology. The emergence of Ethereum once again reiterated the need to split the center, as well as the feasibility and advantages of decentralized distributed applications, to the existing economic market, the financial sector a new direction of development and throw to the society a new entrepreneurial ideas and opportunities.

7. At 5 o'clock this morning, when we were still sleeping, bitcoin rose sharply to US $5300, accompanied by the rapid rise of the leading currencies. After the rapid rise, bitcoin fell sharply. When it fell to US $4700, it quickly returned to US $4900-5000 and stabilized, then the leading currencies also followed bitcoin.

8. < blockquote >

in today's mobile payment era, few people will use coins for payment . A lot of people, they think that mobile payment is more convenient, if you carry RMB, it will be very troublesome, so now less and less people use paper money to pay. In fact, the process of making paper money is also very complicated. The materials used to make coins are different metals. Compared with those rare metals, low-cost metals are more suitable for making coins

< / blockquote >

and those rare metals, such as gold or silver, are suitable for making commemorative coins with collection value . In many countries, some of their currencies are made of alloy, because it is a very ideal material for coinage, and the hardness is improved by mixing with other metals. At the beginning of making coins, we should choose the materials and put the selected metals in the furnace for casting and melting. After many times of rolling in the rolling workshop, the thickness of the coin can meet the requirements of coins, and it can be made into semi-finished procts for further processing{ RRRRR}

with the progress of science and technology, now many mold making machines have become engraving machines for casting to replace the previous manual process . It can improve the accuracy to a certain extent. It used to take a whole day to manufacture, but now it can complete the remanufacturing of the mold within a few hours. After that, it can be pressed on the coin, and the coin will become the currency in circulation

9. Ethereum is also a proct of blockchain 2.0, which is an open intelligent contract complete solution. Bitcoin is the most important application of blockchain 1.0, which completes currency and payment transactions well. But when we need to record and transfer more complex asset types, we need the third step - a more powerful scripting system - to finally achieve Turing completeness (the ability to run any currency, protocol or blockchain). Ethereum is a blockchain based project, which aims to provide a Turing complete scripting language and Turing complete platform

blockchain 1.0 mainly refers to bitcoin. Blockchain 2.0 extends to all assets, while blockchain 3.0 goes beyond currency, finance, even commerce, and all areas of our lives, including politics, social relations, ecation, medical care, etc. According to the prediction and conception of people in the instry, the era of blockchain 3.0 will be realized in the next five years. At that time, blockchain will be recognized and accepted by all the public like the Internet, thus completely subverting our lives

McKinsey has submitted a technical report on blockchain to the Federal Insurance Advisory Committee of the United States. The report calls 2009-2016 the "Dark Age" and believes that all blockchain solutions ring this period are based on bitcoin, and the new era of blockchain will begin in 2016. At that time, the application of blockchain will become unprecedented. Applying an original sentence in McKinsey report: Based on the current development speed of blockchain, we believe that blockchain solutions may realize their full potential in the next five years.

10. Ethernet information blockchain, English Name: Ethernet moeher information, referred to as "eth. M", is committed to the development and construction of big data intelligent blockchain ecology based on the mature blockchain technology of smart contract Ethereum. Every business data will be realized as an intelligent contract, which can realize the existence and ownership of data, And it can trade independently of any specific content platform. This will help rece the dependence of business data providers on their platforms to ensure revenue from their markets and, in turn, on advertisers. Eth. M will be deployed as ERC 20 standard token on eth blockchain. Eth. M will also be used to create and motivate an intelligent business ecosystem to help create, manage data providers and redeem eth. M participants, as well as for digital asset allocation, certificate of ownership and asset transfer
eth. M is characterized by providing a complete intelligent business blockchain architecture for enterprise users and government partners on the Bi platform, providing users with a perfect data import scheme and a variety of classic distributed computing models, which can more quickly solve users' massive data computing problems and effectively rece enterprise costs, And create a new business model on the basis of data security. Blockchain is a new field that needs to be combined with market demand. We can solve some pain points in the instry in data storage security, data retrieval and data filtering. For blockchain framework, business model and technology, we focus on building mature blockchain procts with the most appropriate and proven technology
blockchain, originally just a settlement system of bitcoin, is essentially a decentralized accounting scheme based on cryptography. The technology used by blockchain itself is not a new concept, but a collection of cryptography technologies. Through ingenious design, it realizes the demand of decentralized settlement. However, it is accompanied by some derivative problems. Users are used to transferring and sharing information in the distributed storage space, namely Internet. However, if we want to complete the transfer of money value, we are used to using centralized and trusted third-party transaction intermediaries, such as banks. Although online payment is becoming more and more popular, bank card and password are still needed to register online payment account. The use of blockchain transactions is decentralized and does not require a third-party intermediary. Blockchain realizes the following three important functions: recording transaction information, verifying identity and establishing contract. It's going to be a big change. Because around the world, financial services are the largest sector in terms of market value. Even if it replaces a small part of business, blockchain can have a huge impact on the traditional financial field. At the same time, eth. M blockchain will also improve the efficiency of data management in the whole field. The function of establishing contracts will make the value of blockchain not limited to the financial field. This is the core of eth. M. blockchain can be used to store any information, even software code. That is to say, it can be realized by programming. When the relevant parties provide the relevant key, the transaction can be executed. The same program can also be used to obtain external data: stock index data, weather, news headlines or other data that can be analyzed by computer. In this way, the pre verified contract can be executed automatically when the specified conditions are met. Contracts executed on the blockchain are called "smart contracts"
in the future, eth. M's smart contract application scenarios are very wide, for example:
1. In the field of electric power, if the smart temperature regulator is used to collect the power utilization status of the smart grid in real time, when the wattage consumed by a certain company is monitored to reach a certain amount, the company account and the electric power company's transfer will be completed, and the automatic payment will be realized
2. In the medical field, if a doctor / patient stores the data of blood glucose meter in the form of blockchain, then the patient's physical sign data can be completely and accurately recorded. Blood glucose data can trigger insulin controller to help patients control blood glucose in a safe range
3. In the field of intellectual property supervision, blockchain can be used to monitor the number of times users use, share and a protected proct.
