A. What is Ethereum in platform projects in the blockchain?

Ethereum, Ethereum, referred to as ETH. At the end of 2013, Vitalik released the Ethereum white paper, and in July 2014, the pre-sale of Ethereum began. At that time, people in the circle called this kind of token issuance "coin crowdfunding." Through the 42-day pre-sale, the Ethereum team raised more than 30,000 Bitcoins through the pre-sale of 60,102,216 Ethereum coins; in addition, early contributors who participated in the development before the pre-sale and developers who have been engaged in project research for a long time were respectively At that time, 9.9% of the total amount of Ethereum issued was allocated. Therefore, there were more than 72 million Ethereum coins when Ethereum was officially released. After the Ethereum pre-sale ends, the proof-of-work mechanism PoW will be used for mining, and miners will be rewarded every year based on 26% of the total issuance at that time. In October 2014, Ethereum reduced the block generation time from 60 seconds to 12 seconds. It is now basically stable at 15 seconds, and each block rewards 5 Ethereum coins. Although both use the PoW mining mechanism, the block generation mechanism of Ethereum is still different from that of Bitcoin. Due to the short block generation time of Ethereum, it is easy for Ethereum to form orphan blocks. Orphan blocks refer to blocks that are not on the longest chain. Bitcoin's orphan blocks do not have any block rewards, but in Ethereum, orphan blocks can be referenced. The referenced orphan blocks are called "uncle blocks", and their packaged data will also be recorded in the block. in the chain. Unlike Bitcoin, Ethereum's uncle blocks have rewards, and each uncle block can receive up to 4.375 ether coins. Ethereum is a programmable, Turing-complete blockchain development platform equivalent to a decentralized global computer. On top of a programming system, there are usually some compilation and execution virtual machines for support. JAVA has JVM, and 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 the applications they want on Ethereum. Through the Ethereum virtual machine, you can easily issue digital assets, write smart contracts, build and run decentralized applications, establish decentralized autonomous organizations, etc. Ethereum (ETH) is also known as the fuel within Ethereum. Unlike currency digital assets, Ethereum is not only used for transfers, but also for payment of smart contract fees. In order to avoid the Ethereum blockchain being flooded with junk contracts and junk applications, to build and run smart contracts on Ethereum, you must pay smart contract fees in ETH. For example, to transfer your newly created digital assets on the Ethereum blockchain, you need to pay the handling fee in ETH, not your newly created digital assets.

B. The relationship between Bitcoin, Ethereum and Yuzu

[One keyword to explain the story behind]

If you love me, hug me Me, if you love me, you must kiss me, if you love me, you must care for me. All right. Then I will breastfeed EO todayS.

Speaking of blockchain, most people will think of Bitcoin, Ethereum, and EOS... In fact, these three currencies are also slightly related. With Bitcoin, there is Ethereum. With Ethereum, there is EOS (Youzi), and with Youzi, there are opportunities for various DAPPs and even commercial-level DAPPs to emerge from it.

As more people have a consensus on Bitcoin, the number of transfers is increasing, and the blockchain confirms a transfer every 10 minutes. The size of this block can only accommodate There are more than 4,000 transactions, and they are confirmed one after another according to the amount of the transfer. The transfer amount is relatively small. When Bitcoin transactions are congested, it may even take several days for the transfer to be successful!

Buterin discovered some shortcomings of Bitcoin and created Ethereum for crowdfunding. Anyone who wants to establish a project currency or DAPP on the blockchain can develop it on Ethereum. Now Ethereum The transaction speed of Ethereum is dozens of transactions per second, plus some applications are developed on Ethereum. It is difficult to create a popular DAPP.

Then there is the current EOS. The vision of EOS is to become the underlying architecture of the blockchain, support million-level transfer speeds, and greatly reduce the difficulty of anyone who wants to develop applications on the blockchain. …………

In fact, the current transfer speed of EOS is thousands of transactions per second. If the computer of each node is a supercomputer, a million-level transfer speed per second is still entirely possible. When a large number of projects develop applications on EOS, it is very likely that popular DAPPs will emerge from them. It is likely that in the future, you will learn about blockchain through EOS, not Bitcoin or Ethereum.

Therefore, if you want to develop applications on Yuezi, you must invest a certain amount of EOS and redeem it for RAM. RAM is the token in the EOS world and the memory in the network in EOS. In fact, when a large number of users develop applications, EOS will also grow, and the price of RAM may also increase in the future.

But if the initial price is too high, there will be no users to develop applications on it. Only if more people develop a consensus on Yuezi, Yuezi will have greater value.

So, we need to wait. We are waiting for a large number of applications to come to fruition and for hot-selling DAPPs to emerge from them. It seems that only EOS can support hot-selling DAPPs.

C. What is Ethereum and what is the relationship between Ethereum and blockchain

Ethereum is a new and open blockchain platform that allows anyone to build and Use decentralized applications running through blockchain technology. Just like Bitcoin, Ethereum is not controlled or owned by anyone – it is an open source project co-created by many people around the world.

HebiWhat is different about the Bitcoin protocol is that the design of Ethereum is very flexible and adaptable. It is very easy to create new applications on the Ethereum platform, and anyone can safely use applications on the platform.

Ethereum is a programmable blockchain. Rather than giving users a series of preset operations (such as Bitcoin transactions), it allows users to create complex operations as they wish. In this way, it can serve as a platform for many types of decentralized blockchain applications, including but not limited to cryptocurrencies.

Ethereum in a narrow sense refers to a series of protocols that define a decentralized application platform. Its core is the Ethereum Virtual Machine ("EVM"), which can execute the coding of any complex algorithm. In computer science terms, Ethereum is “Turing complete.” Developers can use other friendly programming languages ​​​​modeled on existing languages ​​​​such as JavaScript and Python to create applications that run on the Ethereum simulator.

Like other blockchains, Ethereum also has a peer-to-peer network protocol. The Ethereum blockchain database is maintained and updated by numerous nodes connected to the network. Each network node runs an Ethereum emulator and executes the same instructions. Therefore, people sometimes refer to Ethereum as the "world computer".

This massive parallel operation throughout the entire Ethereum network is not intended to make the operation more efficient. In effect, this process makes computing on Ethereum slower and more expensive than on a traditional “computer.” However, each Ethereum node runs the Ethereum Virtual Machine in order to maintain the consistency of the entire blockchain. Decentralized consensus makes Ethereum extremely fault-tolerant, guaranteeing zero downtime, and allowing data stored on the blockchain to remain immutable and censorship-resistant.

The Ethereum platform itself has no characteristics and no value. Similar to a programming language, it is up to entrepreneurs and developers to determine its use. But it’s clear that certain application types benefit from Ethereum’s capabilities more than others. Ethereum is particularly well-suited for applications that automate direct interactions between peers or facilitate group coordinated activities across the network.

For example, applications that coordinate peer-to-peer marketplaces or automate complex financial contracts. Bitcoin enables individuals to exchange money without resorting to other intermediaries such as financial institutions, banks or governments. Ethereum’s impact may be even more profound.

Theoretically, any complex financial activity or transaction can be coded on Ethereum automatically and reliably. In addition to financial applications, any application scenarios with high requirements on trust, security and durability - such as asset registration, voting, management and the Internet of Things - will be affected by the Ethereum platform on a large scale.

D. What is Ethereum? What is the relationship between Ethereum and the blockchain?

What is Ethereum:

Ethereum is a project based on Bitcoin. Technology and concepts are applied to computer innovations. Ethereum itself imitates many Bitcoin technologies to maintain the plan.computer platform. Blockchain technology is one of them.
The Ethereum platform can safely run any program that users want.

The advantages of Ethereum over other competing currencies

Before the emergence of Ethereum, there were already some digital currencies that imitated Bitcoin. However, these projects themselves have certain shortcomings and can only support one or several specific applications at the same time. (A better digital currency trading platform is in "Bihui")

However, the reason why Ethereum can surpass the limitations of these previous projects is because of the core idea of ​​Ethereum.

What Ethereum wants to implement is a blockchain protocol with a built-in programming language. Since it supports programming languages, theoretically any blockchain application can be defined in this language and then serve as a An application that runs on the Ethereum blockchain protocol.

Ethereum is designed to be very flexible and adaptable.

Ethereum aims to combine the strengths of blockchain technology in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields. .

Ethereum’s blockchain applications

Ethereum has many blockchain applications, such as gold and stock digital applications, financial derivatives applications, DNS and digital Certification and more.

Ethereum has been implemented by many startup companies in more than 100 blockchain applications.

Ethereum has also been closely followed by some financial institutions, banking consortiums (such as R3), and large companies like Samsung, Deloitte, RWE and IBM, which has also spawned a number of projects such as Simplification and automated financial transactions, merchant loyalty index tracking, gift cards designed to decentralize electronic transactions, and other blockchain applications.

The relationship between Ethereum and blockchain:

Ethereum is a programmable blockchain.

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

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

Like other blockchains, Ethereum also has a peer-to-peer network protocol. The Ethereum blockchain database is maintained and updated by numerous nodes connected to the network. Each network node runs an Ethereum emulator and executes the same instructions. Therefore, people sometimes refer to Ethereum as the "world computer".

E. Why is Ethereum the representative of Blockchain 2.0?

The Blockchain 1.0 era usually refers to the period between 2009 and 2014, represented by Bitcoin. In the development stage of blockchain applications, they are mainly committed to solving the decentralization problem of currency and payment methods; after 2014, developers are increasingly focusing on solving the technical and scalability problems of Bitcoin.deficiencies. At the end of 2013, Vitalik Buterin released the Ethereum white paper "Ethereum: The Next Generation of Smart Contracts and Decentralized Application Platform", introducing smart contracts to the blockchain, opening up the application of blockchain beyond the currency field, thus opening up the area. Blockchain 2.0 era. (A better digital currency trading platform is in "Bihui")

The so-called smart contract is actually a computer contract that can be automatically executed based on prescribed trigger rules, and can also be regarded as a traditional contract. The digital version was proposed more than 20 years ago by Nick Szabo, an interdisciplinary legal scholar and cryptography researcher. This technology was once not used in actual industries due to the lack of programmable digital systems and related technologies, until the emergence of blockchain technology and Ethereum provided a trusted execution environment.

Compared with Bitcoin, Ethereum is a Turing-complete scripting language that supports developers to create and publish any decentralized applications on the platform. From its birth to the present, the world’s Ethereum-based There are more than 200 decentralized applications.

The chief researcher of BitWindow Blockchain said: The blockchain 2.0 era represented by Ethereum has gradually expanded blockchain technology from the currency and payment fields to the financial field. With the development of technology and the wider application of blockchain, the blockchain 3.0 era that transcends the currency and financial fields will be just around the corner. The article is excerpted from BitWindow, China’s professional blockchain and digital currency industry analysis media, adhering to a neutral, objective and dialectical attitude to gain insight into and interpret the latest trends in blockchain and digital currency.

F. What is the relationship between Bitcoin and Ethereum

Bitcoin and Ethereum are different versions of blockchain technology, and they are driven by different goals. .
Ethereum is a major advancement based on blockchain principles. Although Bitcoin is also supported by blockchain technology, the purpose of Ethereum is not to compete with Bitcoin. Both Bitcoin and Ethereum operate on the principles of distributed ledgers and cryptography, but they still differ in many technical areas.
Bitcoin is the earliest virtual token in blockchain technology. It is the medium for transactions and the means of value storage in point-to-point transmission payment systems. Ethereum is an open source public blockchain platform with smart contract functions. It can be said to be a more evolved blockchain technology. Ethereum provides a decentralized virtual machine to process peer-to-peer contracts through the supporting dedicated cryptocurrency Ethereum. The New York Times believes: The Ethereum platform is a public computer run by a network of many users, and Ether is used to allocate and pay for the right to use this computer.
Although Bitcoin and Ethereum are both digital currencies, unlike Bitcoin, the main purpose of Ethereum is not to build itself as a payment substitute, but to facilitate and monetize the operation of Ethereum. This allows developers to build and run distributed applications.

G. What is Ethereum?

With the innovation of blockchain technology, a new platform was born, which is Ethereum. Ethereum is not just a cryptocurrency like Bitcoin, it has other characteristics that make it a giant distributed computer.

So, what exactly is Ethereum?

Specifically, Ethereum (Ethereum) is a programmable, visual, and easier-to-use blockchain that allows anyone to write smart contracts and issue tokens. Just like Bitcoin, Ethereum is decentralized and is jointly recorded by the entire network. The ledger is open, transparent and cannot be tampered with.

Unlike Bitcoin, Ethereum is a programmable blockchain that provides a Turing-complete scripting language, so developers It can be programmed directly in high-level languages ​​such as C language and converted into assembly language, which greatly reduces the difficulty of developing blockchain applications.

To make it easier to understand, for example, Ethereum is like Android in the blockchain. It is a development platform that allows us to develop applications based on Android Framework also writes applications based on blockchain technology. It provides various modules for users to build applications. If building an application is like building a house, then Ethereum provides modules such as walls, roofs, and floors. Users only need to build the house like building blocks. Therefore, in Ethereum The cost and speed of building applications have been greatly improved.

In fact, before there was Ethereum, writing blockchain applications was like this: copy a copy of the Bitcoin code, and then change the underlying code such as encryption Algorithms, consensus mechanisms, network protocols, etc. (Many altcoins are like this, and if they are changed, a new coin will come out).

As for how Ethereum works?

Like other blockchains, Ethereum requires thousands of people running a software on their computers to power the network. Each node (computer) in the network runs a piece of software called the Ethereum Virtual Machine (EVM). If you think of the Ethereum Virtual Machine as an operating system that understands and executes software written in an Ethereum-specific programming language, the software/applications executed by the Ethereum Virtual Machine are called "smart contracts."

However, operating on this computer is not free. You need to pay for the network’s own cryptocurrency, called Ether. Ethereum is largely the same as Bitcoin, except that Ethereum allows you to pay for executing smart contracts on Ethereum.

Going back to the development history of Ethereum, the concept of Ethereum was first proposed by programmer Vitalik Buterin between 2013 and 2014 after being inspired by Bitcoin, which means "next generation encryption". Currency and Decentralized Application Platform" began to develop through ICO crowdfunding in 2014.

As of February 2018, Ethereum is the second-largest cryptocurrency by market capitalization, behind Bitcoin currency.

For many programmers and investors, July 30, 2015 is a big day. After 18 months of gestation, the Ethereum blockchain platform was finally officially born. At about 11:45 a.m. that day in the office in Brooklyn, when the Ethereum blockchain generated its first genesis block, there were many enthusiastic miners behind it who wanted to win the first block, which was exclusive to Ethereum. Electronic currency, ownership of Ethereum. There was thunderous applause throughout the office. It was a terrible day, with a thunderstorm in New York City and noisy flood warnings blasting from everyone's smartphones.

According to the company’s website information, Ethereum is a decentralized application platform. Taking smart contracts as an example, designers can completely eliminate the possibility of crashes, being monitored, being defrauded, or being interfered by third parties. Like Bitcoin, Ethereum uses Ethereum to attract participants, establish a network architecture to verify the trading platform, maintain the operation of the network architecture, and determine by consensus which events have actually occurred, but Ethereum and Bitcoin It is also different. Ethereum provides some powerful tools for those who invest in development to create, and has decentralized software services that can be used from online games to stock trading.

The idea of ​​Ethereum originated in 2013, when the 19-year-old Russian-Canadian Vitalik Buterin, for example, argued with the core developer of Bitcoin that the blockchain network The architecture needs a more stable manuscript language to develop other application software. However, his idea was not adopted, which prompted him to make up his mind to develop a blockchain network architecture consensus that conforms to his own ideas. This company can be said to be His first step was to launch application software on the Ethereum blockchain. If we go back a few years, we will find an interesting comparison.

Torvalds, a master, launched the Linux operating system in the same way as Buterin launched Ethereum. Joseph Rubin, co-founder of Consensus Systems, said when talking about the rise of the blockchain Ethereum, I increasingly feel that it is a waste of time to go to the streets and put up posters to appeal. It is better to cooperate together. In this imbalance The economic system of the society needs to bring about more practical changes.

Like many entrepreneurs, Rubin’s desireHe is also very ambitious. He not only wants to build a great company, but also wants to take the opportunity to solve the world's difficult problems. The company's applications will have dramatic effects on more than a dozen other industries. Their plans include a distributed triple-entry accounting system, which was originally well-received but later suffered from centralized control. The controversial reddit forum has launched a new distributed version, managed by an automatically executed file format. The system is now called smart contracts, covering prediction markets in the fields of business, sports and entertainment, public bidding energy markets, and a complete set of tools that can compete with Apple computers. A business tool for large-scale collaborative collective creation to realize a common management mechanism for companies without management layers.

Ethereum was founded by Vitalik Buterin in 2014. It is a blockchain underlying system, similar to the operating system of the Internet, and the DAPP (decentralized application) developed based on it is similar to It is a software APP developed based on the Internet operating system.

Its emergence is mainly to make up for the shortcomings of Bitcoin. Bitcoin can only implement a point-to-point electronic cash transaction system, but the application of blockchain technology in other scenarios cannot be realized. If you build an underlying basic system for each scenario and then develop it, it will take too much time and energy, and the cost will be very high. For this reason, Ethereum has built an underlying system for developers to use, and developers only need to develop their own DAPP applications based on it. Data from May last year showed that there were more than 200 Ethereum applications around the world.

In addition, Ethereum is also one of the better public chains in the blockchain. However, its transaction speed is too slow and has been criticized by many developers. Ethereum developers are constantly trying to develop sharding technology to change this phenomenon.

The essence of Ethereum is a programmable, visual and simple-to-operate blockchain that allows anyone to write smart contracts and issue tokens (this is why there are so many air coins and MLM coins on the market one of the reasons). Like Bitcoin, Ethereum is also decentralized. The entire network records all situations of Ethereum, and it is open, transparent and cannot be tampered with.

So you want to ask, what is the difference between Ethereum and Bitcoin? In layman's terms, you can think of Ethereum as a programmable blockchain. It provides a set of Turing-complete scripting languages. Subsequent developers can directly program in C language and other languages ​​on this basis, and then convert it into assembly. language, thereby reducing the difficulty of developing blockchain applications. Just like on the Android system, APIs and interfaces are prepared, and users can directly develop apps with this logic. From the beginning of Ethereum to the present, hundreds of applications have been born on Ethereum, and the Russian government has even cooperated with the Ethereum Foundation.

I hope my answer can help you!

At a basic level, Ethereum is a software platform based on blockchain technology. The platform allows building and deploying decentralized applications. What is “ether” in Ethereum? People interested in Ethereum often ask "What is Ether?"

Understanding Ether is very important because it is the basis of Ethereum's functionality. Just like all machines use some kind of fuel, so does the blockchain. Ethereum uses ether, a unique code that can be used as a way to pay for running an application or program. Just like slot machines require coins (or now prepaid cards) to run coins, customers must use ether as payment to run their requested operations on Ethereum.

Everyone else’s answers are really too troublesome

It’s too complicated

Ethereum

In simple terms, this is the conclusion:

Ethereum is equal to BTC+smart contracts+freedom of contracts+deflationary assets+use value< /p>

This conclusion is actually not difficult to understand

The official definition is even more deceitful:

Open source with smart contract function Public blockchain platform. Provides a decentralized virtual machine through its dedicated cryptocurrency Ether (also known as "Ether")

Ethereum simply has this conclusion:

Ethereum is equal to BTC + smart contract + freedom of contract + deflationary assets + use value

Let me tell you briefly

First of all, let’s take a look at the following video: That is, the video of Ethereum founder V God is particularly good. Explanation

Ethereum simply has this conclusion:

Ethereum is equal to BTC+smart contract +Freedom of contracts+deflationary assets+use value

The official definition is even trickier:

Ethereum is a programmable, visual blockchain platform. It has many operating functions, including calculating and summarizing various types of data, etc.

Ethereum is a qualitative leap in blockchain technology! Just like http is the underlying supporting technology of the Internet, and Ethereum can build various ecological dapps based on Ethereum smart contracts

What is Ethereum?

Ethereum is the foundation of the new era of the Internet:

Built-in currency and payments.

Users have personal data sovereignty and will not be monitored or stolen by various applications.

Everyone has the right to use the open financial system.

Based on a neutral and open source infrastructure that is not controlled by any organization or individual.

Creation of Ethereum

Launched in 2015, the Ethereum mainnet is the world's leading programmable blockchain.

Like other blockchains, Ethereum also has a native cryptocurrency called Ether (ETH). ETH is a digital currency that has many of the same functions as Bitcoin. It is a purely digital currency that can be sent instantly to anyone, anywhere in the world. The supply of ETH is not controlled by any government or organization. It is decentralized and scarce. People all over the world are using ETH to make payments or as a store of value and collateral.

But unlike other blockchains, Ethereum can do more. Ethereum is programmable, and developers can use it to build applications unlike before.

The role of Ethereum

These decentralized applications (or "dapps") are based on cryptocurrency and blockchain technology and are therefore trustworthy. That is to say, once the dapps are "uploaded" to Ethereum , they will always run as programmed. These applications can control digital assets in order to create new financial applications; they are also decentralized, meaning no single entity or individual can control them.

Currently, thousands of developers around the world are building applications and inventing new applications on Ethereum, many of which are now available:

1. Cryptocurrency wallet: allows you to make low-cost, instant payments using ETH or other digital assets

2. Financial applications: allows you to borrow, borrow, and invest in digital assets

3. Go Centralized Market: Allows you to trade digital assets, and even trade on "predictions" of real-world events

4. Games: You can own in-game assets and even obtain real-world benefits and more. many.

Ethereum Community

The Ethereum community is the largest and most active blockchain community in the world. It includes core protocol developers, cryptoeconomic researchers, cypherpunks, mining organizations, ETH holders, application developers, ordinary users, anarchists, Fortune 500 companies.

No company or centralized organization controls Ethereum. Ethereum has always been maintained and improved by a diverse global community of contributors, who work on all aspects of Ethereum, from core protocols to applications.

The culprit of Ethereum’s congestion was found, and it turned out to be it!
