Principle of Ethereum block browser

1.

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"

2. Ethereum browser's website is etherscan.io, you can query Ethereum related details. At present, the exchanges that can trade Ethereum mainly include: coin an, fire coin, bitnet, etc.

3. What does it mean that there is no verification of the display in the browser and the release contract code? He certainly didn't have time to do it.

What kind of blockchain technology is popular recently? Blockchain technology is considered to be the brightest star in financial technology, and it may continue to develop in the future. It has many characteristics, including data distribution, data trust and collective consensus mechanism, and most importantly, openness, transparency, anonymity and privacy, According to the data in the blockchain, we can get some basic information of contemporary society

blockchain technology is such a safe and scientific database. It can be simply understood as an authoritative database, in which the basic content is true, verified and audited by others. In terms of financial technology, it is very easy to find some desired data, which is very good for business people

5. You can view the webpage of blockchain transaction records

6. The blockchain browser is the main window to browse the blockchain information, and the content recorded in each block can be viewed from the blockchain browser. Generally, digital asset users will use blockchain browser to query the transaction information recorded in the block. For example, the blockchain browser scheme developed by Yingtang Zhongchuang is mainly used to record in detail the confirmation process of each block, the generation and distribution process of digital currency, and the circulation of digital currency between each block, so as to more completely and publicly disclose the stock, increment, turnover rate and other information of digital currency, The only thing hidden is the owner behind each block.

7. In a centralized exchange, currency is controlled by them. As long as they want to run, they can run
coins should be transferred to their cold wallets for safety
it is suggested to choose a big exchange with good reputation, so as to rece the risk of running away.

8. 1. Wallets have to be open source. The download page can be provided through the network cloud disk, or the source code can be published on GitHub
2. There must be a block browser to facilitate all users to query relevant data information
in theory, these two methods can avoid the situation that people tamper with data without bottom line.
