Blockchain knowledge EOS
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 valuethe content of this article comes from: financial code of the people's Republic of China: application edition, China Law Press

blockchain originated from bitcoin. On November 1, 2008, a person who called himself Satoshi Nakamoto published the article "bitcoin: a peer-to-peer e-cash system", which elaborated the architecture concept of e-cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., marking the birth of bitcoin
extended data
the main features of EOS are as follows:
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
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. 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

EOS% refers to the percentage of eosinophils in the total number of white blood cells, the normal value is 0.5% - 3%< 1. Eosinophilia:
(1). Allergic diseases: bronchial asthma, drug allergy, urticaria, food allergy, angioneurotic edema, serum diseases and other peripheral blood eosinophilia can reach more than 10%
(2). Parasitic diseases: schistosomiasis, Ascaris lumbricoides The number of eosinophils in blood, such as hookworm disease, is usually 10% or more. The number of eosinophils increased significantly in some patients with parasitic infection, resulting in the total number of white blood cells reaching tens of thousands, more than 90% of which were eosinophilic leukemoid reaction
(3) skin diseases such as eczema, exfoliative dermatitis, pemphigus, etc The eosinophils in peripheral blood of patients with psoriasis were slightly or moderately increased
(4). Hematological diseases such as chronic myeloid leukemia, eosinophilic leukemia, lymphoma, multiple myeloma, eosinophilic granuloma, etc. the eosinophils in peripheral blood were increased in different degrees, Some malignant tumors: some epithelial tumors such as lung cancer can cause eosinophilia
(6). Some infectious diseases: most eosinophils decrease in acute infectious diseases, but increase in eosinophils in scarlet fever
(7) Hypopituitarism, allergic interstitial nephritis and so on are often accompanied by eosinophilia
2. EOSINOPENIA:
it is common in the early stage of typhoid fever, paratyphoid fever, major surgery, burn and other stress states, or after long-term application of adrenocortical hormone, and its clinical significance is very small

wish you good health
bitcoin was born to realize a point-to-point cryptocurrency system, while Ethereum realized Turing's complete virtual machine on this basis, making the blockchain a computing platform, and EOS is a computing system by nature. The smart contract on EOS is similar to various programs on our computers. Even the EOS token itself is a contract
generally, we use some kind of cryptocurrency and need an address. When collecting money, others just need to transfer money to this address. However, there is no concept of address in EOS. If users want to use the EOS blockchain, they must create an account on the EOS chain to use it
the creation of this account is actually a contract transaction, which requires an account that can be used to create. This is also a factor that has a high threshold for the use of EOS blockchain, because at the beginning of the launch of EOS, there were few accounts available, and there were no tools (such as wallet) for users to create accounts
moreover, creating an EOS account consumes ram. According to the soaring price of ram, it takes several EOS to create an EOS account, which is also very expensive.
3 am. College
in a village, a spent 3000 yuan to buy a cow of B, how to record this account
so a and B found a mutual trusted C to record the account, but later a and C colluded and did not admit that a had bought B's cattle, so the deal became rough and disputes continued
later, B had another cow. Of course, B didn't sell it to a this time, because a had no credit, so he gave it to d. This time, instead of looking for witnesses, they went to the whole village to roar after the transaction. B said Wang Erhua paid 3000 yuan to buy a cow from me, d also went to the whole village to shout that I paid 3000 yuan to buy a cow from B, so there were many people in the village to record the transaction. In this way, there will be no bad debts, which is called decentralized and distributed accounting
here comes the problem
when you yell, are the villagers willing to charge for you, just because you have a big face
therefore, the first person to record accurately will get some bitcoin rewards
someone asked, what if two people finish the first record at the same time
in order to avoid this problem, it is necessary to set rules, for example, to answer a question first, or to record with feet, and it must be written in block letters. If you set a series of rules, there will not be many firsts
in the network, there are a lot of transactions going on every day, and there are also many people recording, and finally they get the reward of bitcoin. This process is the legendary mining
Mining requires a lot of equipment. We call these computer equipment mining machines
in this way, all the processes are in one system. The system will encapsulate the data every 10 minutes to form a box full of data, which we call blocks
with the continuous generation of blocks, they are linked together to form a blockchain.
