Virtual currency Ethernet
Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum")
The token on theblockchain is called ether, and the code is eth. It can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum
the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, with the general meaning of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin
extended data:
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
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 onembedded 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 SDHPOS (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 betweenand 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
extended materials:
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 valuea single new server has the advantage of collecting herbs, which consumes a lot of water for reclaiming wasteland, and the inscriptions also use herbs
shares are in legal currency
in principle, the coin circle can buy and sell other currencies in any currency
this will lead to various currency pairs
usdt, USD, usdc, tusd and Pax can be understood as US dollar. The basic exchange rate and US dollar are 1:1, with little fluctuation
BTC / usdt. This is a bitcoin usdt pair, the bitcoin price in usdt
EOS / BTC, which is the price of EOS in BTC.
Mining requires powerful computing power and a large number of repeated operations. Although the performance of CPU is powerful, because the logic is too complex, it is more suitable for complex logic operation, and it is not suitable for mining, which is simple and brainless but has a huge amount of calculation. And the graphics card, especially amd graphics card, because of its own design of multiprocessor characteristics and naturally suitable for a large number of violent computing and other characteristics, is very suitable for mining this "heavy physical work"
that's why the price of graphics card is soaring e to mining.
the Central Bank of Nigeria banned cryptocurrency transactions, reflecting Nigeria's distrust of this currency theoretically, digital cryptocurrency is a kind of digital asset that can be exchanged with fiat money. People trade through encrypted wallet addresses and invest in digital cryptocurrency. But at present, in China, the status of digital cryptocurrency is less than legal tender
smart contract is the most important and significant feature of Ethereum, which refers to the computer program that can be automatically executed on Ethereum blockchain . In short, a smart contract is a program that is automatically executed according to the program set by the creator. One of the drawbacks of bitcoin is the waste of computing power. In a fixed ten minute block time, some temporary branches of the blockchain are discarded by the main chain because they are not connected to the main chain. However, this part is also obtained by miners using a lot of computing power, which leads to a waste of computing power and damages the enthusiasm of miners. On the basis of bitcoin, although Ethernet coin will increase the blocking efficiency to 15 seconds, it will also bring more temporary branches of the blockchain, which will lead to more waste of computing power
Ethereum, the world's second largest cryptocurrency, broke through $3000 for the first time on Monday, and rose further on Tuesday, once breaking through $3400, reaching a new high. Its market value once reached US $395.2 billion, ranking 18th in the global asset market value, surpassing MasterCard and NVIDIA and approaching Wal Mart. Traders attribute the rise of bitcoin to the rise of bitcoin at the end of 2020, and the upgrade of blockchain Ethernet makes bitcoin more useful. So far this year, Ethereum has grown by about 365%
bitcoin network is actually a distributed database, and Ethernet goes a step further. It can be seen as a distributed computer: the blockchain is the ROM of the computer, the contract is the program, and the miner of Ethernet is responsible for the calculation and plays the role of CPU. Of course, this computer is not and can not be used for free, otherwise anyone can store all kinds of junk information and carry out all kinds of trivial calculations
OK, that's what we're going to share in this issue
the climate is hot and humid in summer. When people sweat in hot weather, the watch may leave green or black marks on the wrist when it encounters sweat. Due to the different pH value in sweat, the degree of clock erosion is also different. Therefore, it is an important issue for watch lovers to take the initiative to maintain their watches
watch maintenance in summer
the reason why the watch turns green with sweat is that the watch factory adopts gold-plated copper-clad plating which is easy and beautiful in color, but if the gold-plated technology is not handled properly, it will cause the watch oxidation. Nowadays, PVD stainless steel plating technique is widely used in gold plating of watches and clocks, so it is rarely found. Therefore, it is recommended to buy stainless steel or K-gold materials. As for the problem of wrist blackening when wearing a watch, it is directly related to poor air quality and st stuck in the watch strap for a long time. In this case, it's best to give it to a professional watch shop for cleaning. You should also pay attention to the cleaning of the watch when you wear it on weekdays.
