Which technology is higher, apple chain or Ethereum

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. Like bitcoin, Ethereum is neither controlled nor owned by anyone - it's an open source project created by many people around the world

Different from bitcoin protocol, Ethereum is very flexible and adaptable. It's very easy to create new applications on the Ethereum platform. Anyone can use the applications on the platform safely

Ethereum is a programmable blockchain. It does not give users a series of preset operations (such as bitcoin trading), 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, including but not limited to cryptocurrency

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

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"

this massive parallel operation throughout the Ethernet network is not to make the operation more efficient. In fact, this process makes computing on Ethereum slower and more expensive than on traditional computers. However, each Ethereum node runs Ethereum virtual machine in order to maintain the consistency of the whole blockchain. The consistency of decentralization makes Ethereum have high fault tolerance, zero downtime, and can keep the data stored on the blockchain unchanged and anti censorship

Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks

for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound

in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale

2. Many blockchain projects are developed on the basis of Ethereum's open source technology. Ethereum is a common public chain technology, and the deployment of applications on Ethereum has high requirements for developers. Developers need to consider many technical details and business processing logic, as well as security vulnerabilities such as smart contract overflow
the trust union credit alliance chain is located in the financial public chain, which is oriented to the high-frequency financial application scenarios in the field of credit and assets. It does not use eth, EOS, Neo and other general public chains, but uses the account structure of star network, adopts the lightweight intelligent contract layer, and the whole technical architecture is molarized according to "high aggregation and low coupling", This enables the trust union credit alliance chain to adapt to the requirements of rapid development, rapid implementation and timely response of Internet financial procts.

Blockchain 1.0 era usually refers to the development stage of blockchain application represented by bitcoin from 2009 to 2014. They are mainly committed to solving the problem of decentralization of currency and means of payment; After 2014, developers pay more and more attention to solve the technical and scalability problems of bitcoin. At the end of 2013, vitalik buterin released Ethereum white paper "Ethereum: next generation smart contract and decentralized application platform", which introced smart contract into blockchain and opened the application of blockchain outside the currency field, thus opening the era of blockchain 2.0< The so-called smart contract is actually a kind of computer contract that can be automatically executed based on prescribed trigger rules. It can also be regarded as a digital version of traditional contract. It was proposed by interdisciplinary legal scholar and cryptography researcher Nick Szabo more than 20 years ago. This technology was once not used in the actual instry because of the lack of programmable digital system and related technologies, until the emergence of blockchain technology and Ethereum provided a trusted execution environment for it

compared with bitcoin, Ethereum is a complete scripting language of Turing, which supports developers to create and publish arbitrary decentralized applications on the platform. Since its birth, there have been more than 200 decentralized applications based on Ethereum in the world

the chief researcher of bitwindow blockchain said: in the era of blockchain 2.0 represented by Ethereum, blockchain technology has graally expanded from the field of currency and payment to the field of finance. With the development of technology and the wider application of blockchain, the era of blockchain 3.0 beyond the monetary and financial fields will be around the corner. This article is excerpted from bitwindow. China's professional blockchain and digital currency instry analyzes the media, and adheres to a neutral, objective and dialectical attitude to understand and interpret the latest trends of blockchain and digital currency

4. LF CEO Ma Haobo said in the "cannon interview": the problems urgently solved by the underlying facilities of the next generation blockchain are very similar to those of Ethereum. It is an underlying decentralized computing platform. On the platform, users can easily deploy smart contracts and run them, but? LF thinks that Ethereum has three problems and hopes to solve them. The first is its overall low performance and TPS; Second, resources are not isolated. When crowdfunding for a certain contract is very popular, Ethereum network will block and other contracts cannot be executed; The third problem is reflected in the governance structure, who this blockchain belongs to, how it develops, and how to solve the problem of bifurcation.

This is two different concepts. According to different standards, blockchain can be classified into three categories:

& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain

 &# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain

 &# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain

the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process

At 1:00 a.m. Beijing time on September 11, 2019, Apple's new proct launch in the fall of 2019 was held in jobs hall, and the highly watched iPhone 2019 officially appeared. At the press conference, Apple released the iPhone 11 series, the new iPad and the apple watch

the iPhone 11 series has released three mobile phones, namely, iPhone 11, iPhone 11 pro and iPhone 11 Pro max. These three mobile phones mainly upgrade the chip and camera functions, and launch three cameras. The three cameras are arranged in a square, which is called "Yuba" design by the outside world. This design is also a big change in the appearance of Apple mobile phone this year

in March 2018, apple took off mining MAC app calendar 2 for excessive consumption of resources. Calendar 2 was previously exposed to have mining scripts that were used to extract monero without user permission

in April 2018, Apple introced the interleaver API protocol from ripple for its apple pay. Apple pay can integrate the protocol on its proprietary browser Safari OS 11.1 and IOS 11.3

in May 2018, Apple's own stock software has added BTC, ETH, BCH, XRP, EOS and other mainstream digital currency market and dynamic information, so that users can view real-time opening / closing price, market value and news information

in June 2018, apple updated its code of conct for developers, explicitly prohibiting the use of IOS devices to "mine" bitcoin and other digital currencies, in order to prevent CPU loss

7. Jinwowo will focus on blockchain technology to promote the legal circulation and commercial application of big data. The following is the development trend of blockchain in 2018 analyzed by jinwowo:
1. Asia and the Middle East will actively promote blockchain
2. Network security requirements will drive the popularization of blockchain
3 - all instries will fully invest in blockchain application technology
4 - automation and privatization are coming.

8. 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.

9. The difference between laikelib and Ethereum is that Ethereum is a blockchain technology framework, and laikelib is similar to Ethereum. The difference is that laikelib only needs to synchronize the data of the chain that is needed or the user is interested in, which is faster and smaller. Ethereum must synchronize all the chain contents to achieve the same effect.

10. The most fierce competition in the field of blockchain is actually the battle of "main chain"
whoever can become the main chain of the basic layer of the blockchain is likely to become the future giants such as apple and Microsoft
it's said that the main chain of Jinyou chain is half finished. At least the direction of blockchain technology is right. Next, we'll wait for them to use the main chain to see the effect on the game platform
I'm still optimistic
