EOS force second processing

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 is a blockchain development platform with strong scalability and support for large-scale commercial applications. First of all, EOS adopts dpos consensus algorithm and other technical means, and is expected to realize millions of transaction requests per second, which will be able to support thousands of commercial dapps. Ethereum is a public chain. Every application running on the Ethereum chain will consume the resources of the whole chain. However, EOS is just a blockchain infrastructure. Developers can freely create a public chain on EOS. The use of resources between chains will not be affected, and there will be no network congestion caused by the huge consumption of indivial application resources. Secondly, there is no need to consume EOS token to transfer and run smart contracts on EOS, which will attract more users

EOS is a public chain system at the bottom of blockchain developed by block. One, which is specially designed to support decentralized application of Commerce, and its code is open source

bitcoin is called blockchain 1.0 because it opens up the world of digital cryptocurrency and takes a decisive step from 0 to 1

Ethereum is known as blockchain 2.0, because it provides Turing complete virtual machine that can run smart contracts, bringing unlimited possibilities

and EOS is called blockchain 3.0, why? Two words: performance

The positioning of EOS is the slogan of its home page:

English: the most powerful infrastructure for decentralized applications

Chinese: the most powerful decentralized application infrastructure

EOS expects to be an enhanced version of Ethereum, a high-throughput intelligent contract platform

although Ethereum has complete functions, it is limited by its design choice. Due to the block output speed of 15 seconds, the transaction throughput is far from large-scale practical level, which is only about 30 ~ 40tps (transaction / s). EOS, on the other hand, has chosen a different technology route, with the goal of achieving a considerable million TPS, which is quite attractive considering visa's actual processing speed of 1700tps

consensus mechanism of EOS

the reason why the throughput of bitcoin and Ethereum is so low is that they are constrained by the application scenario they envision and the consensus mechanism they choose for the scenario - both of them assume that the environment in which the system runs is totally untrustworthy, so they both adopt the consensus mechanism of proof of work

consensus, as the name suggests, is to reach a unified understanding of something - for blockchain, something refers to the confirmation of the transaction - any node to submit a transaction needs everyone's approval

the pow mechanism currently adopted by bitcoin and Ethereum is the design of the legendary Nakamoto Tsung. Under this mechanism, in order to obtain the bookkeeping right and digital currency reward, miners need to constantly dig for the compliant hash value, and confirm and package the transaction data through the consensus of hash value. POW has no access threshold, and any node has equal rights to participate in bookkeeping. Of course, the probability of winning is related to computing power:

the price of ram is based on Bancor algorithm, that is, it is regulated by market supply and demand: if the supply of ram exceeds the demand, more EOS certificates are needed to buy ram, At this time, more EOS certificates can be obtained by selling ram

memory is a consuming resource, which cannot be redeemed and can only be bought and sold. Take the issue of currency on EOS as an example. At present, the issue of currency requires 20m of memory. An EOS can buy 20KB. According to the current storage price, issuing a currency will consume 1000 EOS. This is the source of EOS memory consumption

Course Overview

this course is for friends who are interested in the development of EOS decentralized application.

EOS means 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. It is not a currency like bitcoin and Ethereum, but a token based on the EOS software project, known as blockchain 3.0

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. In short, having EOS is equivalent to having a set of rent to collect rent for others, or having a piece of land to rent for others to build a house
