Advantages and disadvantages of block chain EOS Technology

1.

There are four different definitions of EOS, specifically as follows:

1, EOS: electronic and electrical

electrical over stress (EOS) is a common cause of damage to components, which is manifested by overpressure or over-current to proce a lot of heat, so that the internal temperature of components is too high to damage components (commonly known as burn out), It is a common way to damage electronic devices caused by pulse in electrical system

Embedded operating system (EOS) refers to the operating system used for embedded system. Embedded operating system is a kind of widely used system software, which usually includes hardware related underlying driver software, system kernel, device driver interface, communication protocol, graphical interface, standardized browser and so on

embedded operating system is responsible for the allocation of all software and hardware resources, task scheling, control and coordination of concurrent activities. It must reflect the characteristics of the system in which it is located and be able to achieve the functions required by the system by loading and unloading some moles

(3) EOS: Ethernet based on SDH

POS (packet over SDH) and EOS are two different ways to implement IP services in SDH network. POS technology appeared earlier, EOS appeared later, and some technical evolution has been made

The main difference between

and POS is that the Ethernet frame is encapsulated first, then mapped to the VC (virtual container) of SDH / SONET, and then the information is processed according to the cross mapping system of SDH

4, EOS: blockchain

EOS can be understood as enterprise operation system, which is a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture, which aims to extend the performance of distributed applications. Note that it is not a currency like bitcoin and Ethereum, but a token based on the EOS software project, known as blockchain 3.0

the characteristics of block chain (EOS)

1. EOS is a bit similar to Microsoft's windows platform. By creating a developer friendly underlying platform of block chain, it supports multiple applications to run at the same time and provides the underlying template for the development of DAPP

EOS solves the problems of delay and data throughput by means of parallel chain and dpos. EOS can process thousands of data per second, while bitcoin has about 7 transactions per second, and Ethereum has 30-40 transactions per second

There is no service charge for EOS, and the general audience is more extensive. The network and computing resources needed to develop DAPP on EOS are allocated according to the proportion of EOS owned by developers. When you have EOS, it is equivalent to having computer resources. With the development of DAPP, you can lease your EOS to others. From this point alone, EOS has a wide range of value

2. EOS's vision is to become a public chain that can run a large number of commercial applications, and its core feature is "commercial"
in order to ensure decentralization and security, current public chain projects such as bitcoin and Ethereum have certain limitations in block scalability. Although the introction of Ethereum's smart contract has greatly enriched the application of blockchain, it also reces the threshold of issuing coins, making Ethereum's network very congested. Many existing public chains have the problems of slow network transfer speed, high cost, low concurrency or poor stability, which can not support the operation of real large-scale commercial applications
according to the white paper of EOS, EOS adopts the graphene block chain architecture, and the bft-dpos consensus mechanism reces the number of verification nodes, but makes the scalability of EOS significantly enhanced, and can support fast transaction processing speed. At present, bitcoin system can transfer about 7 times per second, while Ethereum can transfer 15 times per second; In contrast, EOS's white paper says it is expected to reach a million level TPS in the future
in addition, EOS provides a good development environment for users and developers. The transaction on EOS network does not need to charge service charge, which improves the user experience and makes it easier to attract users; EOS provides developers with a friendly underlying mole, which can support a variety of programming languages and rece the difficulty of DAPP development. Developers can focus more on the function implementation of the developed application.

3. Ethereum focuses on smart contract and Turing. EOS is based on blockchain operating system. Ethereum and EOS are two top blockchains. At present, there are bottlenecks in blockchain technology and narrow application fields.? LF cluster + cloud server is the most advanced blockchain 3.0 at present. Focusing on different blockchain projects such as public chain, storage chain, Im chain, asset chain and application chain, the advantage lies in resource isolation: each smart contract has its own blockchain, and the governance and development of proxy voting system of token holders has the most development prospect.

4. Hello, we are Shanghai wanglian Information Technology Co., Ltd. compared with traditional technology, blockchain has the property that cannot be tampered with. Vonetracer, the blockchain traceability system launched by our company, adopts a variety of data acquisition methods, one thing and one code, which is true and reliable. It applies instry-leading technology, and the bottom layer adopts the baas platform of blockchain service developed by wangchain. This kind of technical characteristics can ensure that the data is different from the traditional traceability, and the data reliability will be greatly improved.

5. 1、 Decentralization:
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain< Second, openness:
the foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to all. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent< Third, independence:
based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention< Fourth, security:
as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity:
unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transmission can be carried out anonymously
Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy

6. The biggest feature of jinwowo network technology analysis blockchain is decentralization
at present, the traditional database is centralized recording and storage. Even for remote disaster recovery and cloud storage, it only changes the storage location from one place to multiple places, from local to cloud. If there is a problem with the central server, the disaster recovery database will stop updating data; The blockchain database is distributed record, distributed storage and distributed propagation. Each information is transmitted by a single node to all other nodes in the whole network. Each node is responsible for data recording and storage. No centralized or third-party organization is responsible for management. If one node has problems, other nodes will continue to update and store data, Through the way of decentralization, the stable operation of the system is maintained, and the information is complete and reliable.

According to reports, blockchain has the advantages of decentralization, distrust and tamper proof

compared with the Internet, the blockchain network conceived by Cosmos not only realizes information interaction, but also realizes the transmission of asset value. Through the IBC cross chain protocol, the token can be transferred across the chain between the blockchains based on Cosmos' tendermint core. For the public chains based on POW consensus mechanism like Ethereum, pegged zone can be used to bridge

Advantages and disadvantages of the use of Puyuan EOS:

1, advantages:

EOS has its own theoretical basis: component oriented, the so-called component oriented is to define a structure (can be considered as a function of the same thing). In the structure, define input and output to form a component

for each HTTP access, a ThreadLocal variable will be created to store an XML tree. In the running process of this thread, it will keep adding, modifying, and querying nodes in the location tree. This process is implemented using XPath. It is said that the part of XPath is rewritten by themselves to improve efficiency

The development of EOS is very convenient. It has already defined many components, such as database storage components (actually a group of static SQL methods), which can complete a function by drawing a diagram. So its development speed is very fast

EOS has a complete set of debugging, publishing and management mechanism. It even has its own server, so the management is more convenient

EOS has an embedded workflow system, which can complete the design of workflow only by drawing

The

component can be easily published as web service, and can be used to develop simple web application based on database

The components provided by

have been strictly tested by manufacturers, so it is easy to apply. Graphical tools rece the possibility of errors

2. Disadvantages:

from the perspective of technology and employee development, people who use it feel that their competitiveness in choosing jobs is disappearing

from the perspective of tools, EOS is at best a development platform, not its boasted SOA business platform, all business development can not provide any available business framework. We need EOS developers to summarize blood and tears before developing

from the system point of view, there is no possibility to shift the value of things developed on EOS. It is totally impossible for you to develop a satisfactory mole on EOS and use it in other non EOS projects. This is a disaster for a company or indivial who wants to accumulate

Compared with the traditional development of OO and J2EE, EOS is easy to use and has a short learning curve. However, this is controversial. The knowledge of EOS is not universal

the development of EOS page is very inconvenient. Although the support of RIA is not as good as it boasts, eos5 is still the most used version in the market. This version came out in 2005. At that time, it was very good that the web development platform was so strong. At present, eos6 released this year is not international, At least no one in China can get better than it

On the surface, there is little difference between eos5 and eos6, which are component assembly. In fact, there is a big difference: in eos5, XML is used for data transmission, but Java objects are used in 6. This change will make a qualitative leap in performance

in addition, he is in line with SCA and SDO standards, which can at least show that he is an open thing, not a car made behind closed doors. If the software is to regulate the business, EOS is still good; If the software is designed to be abused by users or decision makers, EOS has no value
