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 blockchain has exposed three major problems, and its founder vitalik buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied 20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of Ethereum.

3. Ethereum, ETH for short. At the end of 2013, vitalik released the white paper of Ethereum, and in July 2014, the pre-sale of Ethereum began. At that time, insiders called this kind of token issue "crowdfunding". Through the 42 day pre-sale, the Ethereum team raised more than 30000 bitcoins through the pre-sale of 60102216 Ethernet coins; In addition, the early contributors who participated in the development before the pre-sale and the developers who have been engaged in project research for a long time are allocated according to 9.9% of the total amount of Ethernet coins sold at that time. So when Ethereum was officially released, there were more than 72 million Ethereum coins. After the end of Ethereum's pre-sale, it uses the proof of work mechanism POW for mining, and rewards the miners according to 26% of the total amount issued at that time every year. In October 2014, Ethereum reced the block output time from 60 seconds to 12 seconds, and now it is basically stable at 15 seconds, with 5 etheric coins awarded for each block
although the pow mining mechanism is adopted, the block out mechanism of Ethereum is different from that of bitcoin. Due to the short block time of Ethereum, Ethereum is easy to form isolated blocks. Isolated blocks refer to the blocks that are not on the longest chain. Bitcoin's isolated blocks have no block rewards, but in Ethereum, isolated blocks can be referenced. The referenced isolated blocks are called "Uncle blocks", and their packaged data will also be recorded in the blockchain. Unlike bitcoin, Ethereum's TERT block has a reward, and each TERT block can get a reward of 4.375 Ethernet coins at most
Ethereum is a programmable and Turing complete blockchain development platform, which is equivalent to a decentralized global computer. In a programming system, there are usually some virtual machines to compile and execute. Java has JVM. In Ethereum, there is also Ethereum's virtual machine EVM, which can execute any complex algorithm code. Developers can use existing programming languages such as JavaScript or Python to create their own applications on Ethereum. Through Ethereum's virtual machine, you can easily issue digital assets, write smart contracts, set up and run decentralized applications, and set up decentralized autonomous organizations
eth is also known as the internal fuel of Ethereum. Unlike currency digital assets, Ethereum is not only used for transfer, but also for payment of smart contracts
in order to prevent the Ethereum blockchain from being full of junk contracts and junk applications, and to establish and run smart contracts on Ethereum, you must use eth to pay for smart contracts. For example, when you transfer your newly created digital assets on the Ethereum blockchain, you need to use eth to pay the handling fee instead of your newly created digital assets.

The price of eth is probably going up today

Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)

the Ethernet system is the most widely used public blockchain system supporting complete application development. Compared with bitcoin, Ethereum belongs to the category of blockchain 2.0, which is a new blockchain system designed to solve some problems of bitcoin network. The design of bitcoin is only suitable for the scenario of encrypted digital currency, it does not have Turing completeness, and it lacks the concept of saving the real-time status of the account. Moreover, it has the problems of efficiency and resource waste caused by POW mechanism. Bitcoin's blockchain network has the defect of insufficient scalability

Blockchain platforms include Ethereum, Asch and other underlying application development platforms

Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)

arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises

extended data

in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: public account book for all transactions

by using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently. The blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design is a source of inspiration for other applications

bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications

Take a blockchain API tool that I am currently using as an example

previously, I occasionally found bctools , which can quickly and conveniently test and verify BTC and EOS blockchain API. At the same time, these API interface test network and main network can be verified on bctools ; If you are interested, you can go http://bctools.io Use it

at present, Apis on bctools seem to have the following types:

eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0", and uses the blockchain technology "Ethereum" different from bitcoin

The system of

Ethernet coin is the most widely used public blockchain system supporting complete application development. Compared with bitcoin, Ethereum belongs to the category of blockchain 2.0, which is a new blockchain system designed to solve some problems of bitcoin network

extended data

related background:

the emergence of Ethereum is to help users more easily use blockchain technology for application design. According to BARTLIN, the purpose of Ethereum is to create a more general blockchain platform, which can allow users to easily create blockchain based applications and avoid users having to build a blockchain in order to create a new application

generally speaking, the previous blockchain was only a single tool or at most a combination of multi-functional tools, while Ethereum is the smartphone of blockchain, and users can use the smartphone to build any "application" they need. Therefore, BARTLIN said that the application of blockchain is not limited to cryptocurrency. It has great potential and can be applied to all walks of life. It can bring significant benefits to enterprises and organizations of all sizes

9. 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.
