① How to play Eos? Is it suitable to enter now?

Of course it is Canon's EOS300. The reason is to maximize the use of resources. It and the lens are completely compatible with current Canon digital cameras. For SLRs, its autofocus can also be changed to Ricoh's full manual focus, while Ricoh 3000D can only focus manually and is not suitable for Pentax machines

② What is EOS and what are the characteristics of EOS

EOS

Concept:

It can be understood as Enterprise Operation System, a blockchain operating system designed for commercial distributed applications.

EOS is somewhat similar to Microsoft's Windows platform. By creating a developer-friendly blockchain underlying platform, it supports multiple applications running at the same time and provides an underlying template for developing decentralized applications.

Main features:

When we use blockchain, we need to consume various resources, including node computing power, bandwidth, etc. These resources all have costs. In ETH, the cost of using these resources is the consumption of ETH, so a handling fee is charged for transferring tokens. But in the design of EOS, using EOS is free.

A vivid metaphor: ETH is "oil", a consumable product, and a little bit is consumed every time you transfer. EOS is a "real estate". You can use the schools, hospitals and other infrastructure around the real estate to live, seek medical treatment, and go to school without consuming the value of the house itself. Once you own the real estate, you can also rent it out to others for rent.

③ Deeply understand the token in your hand - EOS

What is EOS? Some people say it is "$5 billion in the air", some say it is the Microsoft of the blockchain world, and some say it is blockchain 3.0. For me, it was my first ICO. Because I can only get in but not get out, I still have a lot of money in my hands. I need to know more about its future.

The purpose of the EOS (Enterprise Operation System) project is to create a commercial operating system at the bottom of the blockchain, such as WIN, Android, etc. in computers. The company behind EOS is Block One, registered in Hong Kong. The white paper was released on June 5, 2017, and the ICO started at 21:00 on June 26. The first phase of the sale ended on July 1, with a total of 200 million tokens and US$180 million raised, including my small contribution. . Then came the year-long (as of June 1, 2018) second phase of the ICO, which released a total of 700 million tokens in 350 consecutive 23-hour windows of 2 million tokens each. The main developer of EOS is the founder of BTS and BM (Byte Master), the founder of STEEM.), whose real name is Daniel Larimer, is a serial entrepreneur.

EOS was born to address the bottlenecks of existing blockchain applications. These flaws are as follows:

1. The transaction frequency supported by existing blockchain applications is too low, such as BTC is 3 per second, ETH is 30, and credit card is 20,000 per second, the gap is huge.

2. Transaction fees are too high. I feel this deeply. It costs several yuan to withdraw 2 coins at a time, and the absenteeism fee is too high. If transaction fees are too high, it will definitely hinder the popularity of blockchain applications.

3. There is currently no easy-to-use operating system for blockchain. Although ETH appears in smart contracts, it still has no features or built-in functions. In the long run, it cannot assume the important role of an operating system.

In response to the above defects, EOS has proposed corresponding solutions. EOS uses DPOS (delegated proof mechanism), which can increase the transaction frequency to hundreds of thousands; it uses parallel processing to make the transaction scale reach millions. In this way, it can support thousands of applications (DAPPs) based on it to run simultaneously. EOS waives transaction fees and instead uses a mechanism of token ownership to determine resource utilization. EOS has many built-in basic functions and provides common modules to facilitate rapid development.

It is worth noting that EOS’s DPOS technology is completely different from BTC’s POW (Proof of Work) method. Although POW is fair, it consumes a lot of time and computing resources. DPOS was proposed by BM and was first used in BTS. This mechanism is similar to the shareholders' meeting system of a joint-stock company. EOS token holders vote to elect authorized representatives as board members (appointed witnesses). The work of EOS miners is completed by these board members, but it is held 24 hours a day. A block is generated every three seconds, and one election takes 63 seconds. Because there is an incentive to produce blocks (generated by inflation, no more than 5%), miners have enough motivation to complete the task. This mechanism can also avoid the occurrence of forks because the relationship between miners is cooperation rather than competition.

Use teacher Li Xiaolai’s blockchain investment MBA principles to analyze EOS?

1. Does the world really need this application? Blockchain requires an operating system.

2. What problems have been solved that were not solved before? Solve the problems of low transaction frequency, high fees, and lack of easy-to-use operating systems.

3. Is decentralization really necessary? Yes, only decentralization can establish a trust mechanism for smart contracts.

4. Can accounting disclosure really improve efficiency? Same as 4, ensuring the safe transfer of assets and contract execution.

5. How likely is itBecome a DAC? The rules are clear and it is an autonomous organization at the center of the district.

EOS has only been around for three months, but it is favored by many people in the industry. There are already many ICO projects that clearly support EOS, such as PRESS ONE, European Chain, etc. If you want to crowdfund now, it is more troublesome; if you want to buy in the secondary market, you can do it at www.bitfinex.com.

Although EOS is now at the forefront, it doesn’t matter. Without some irrational and exaggerated pursuit, it may be more conducive to the development of technology. I am still optimistic about the blockchain and EOS, which solves the bottleneck of the blockchain. Whether you believe it or not, I believe it and continue to hold on and never let go.

④ If you buy eos coins on Huobi, do you need to map it yourself and mention your wallet?

No, generally major exchanges will do the mapping for you. EOS can be understood as Enterprise Operation System, a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture introduced to achieve performance expansion of distributed applications. Note that it is not a currency like Bitcoin and Ethereum, but a token released based on the EOS software project, called Blockchain 3.0.

Previously, EOS had almost the entire currency circle involved due to the super node election campaign. : Exchanges, mining pools, and big Vs are coming one after another, and even the famous overseas "Wenzhou Gang" has rushed to enter the market with billions of assets. This situation once drove the price of EOS to rise steadily and call for sales. Non-small data show that in mid-to-late March, EOS was in a low-level hovering period. On March 19, the price was only US$4.02, and the total market value of EOS was US$3 billion.

As we enter April, more teams and individuals continue to pour into this annual drama in the currency circle. On April 11, AntPool announced its participation. On the 20th, Erye Bao arrived. On the 24th, the cryptocurrency exchange Bitfinex and Huobi Mining Pool also announced their participation in the super node election. Suddenly, EOS formed a wave of strong momentum, boosting the price to rise. By April 30, the price of EOS surged to US$20.05, and its market value reached US$16.5 billion.

In May, the situation began to change. In line with the downturn of the digital currency market, EOS also started a downward trend. By May 31, the EOS price had fallen to a small bottom, only $11.94. The following week, as the original mainnet launch date of June 8 approached, the price of EOS bucked the trend and rose, with the price rising to $14.29 that day.

Unexpectedly, on June 8, because 1/3 of the participating nodes voted against it, the mainnet launch failed and had to be postponed. On June 10, the launch was launched again, but the online voting rate was only 1.77%, failing to reach the 15% voting rate required for the mainnet to go online and failing to go online again.

This situation was quickly transmitted to the market price. Within just a few days, the price of EOS went downhill again, falling from US$14 to US$13 to US$11. On June 14, it even broke through Ten”, sliding to $9.68. As of June 28, the price of EOS has fallen by nearly 60%.

⑤ What is EOS

EOS has four different meanings, as follows:

1. EOS: electronic and electrical

Electrical Electrical Over Stress (EOS) is a common cause of damage to components. Its manifestation is that overvoltage or overcurrent generates a large amount of heat energy, which causes the internal temperature of the component to be too high and damages the component (often called burnout). A common way to damage electronic devices is caused by pulses in electrical systems.

2. EOS: Embedded Operating System

Embedded Operating System (Embedded Operating System, referred to as: EOS) refers to the operating system used for embedded systems. The embedded operating system is a widely used system software, which usually includes hardware-related underlying driver software, system kernel, device driver interface, communication protocol, graphical interface, standardized browser, etc.

The embedded operating system is responsible for the allocation of all software and hardware resources, task scheduling, control and coordination of concurrent activities of the embedded system. It must embody 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 certain modules.

3. EOS: SDH-based Ethernet

POS (Packet Over SDH, SDH-based packet switching) and EOS are two different implementation methods for SDH networks to carry IP services. . POS technology appeared earlier, and EoS appeared later, with some technological evolutions.

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

4. EOS: Blockchain

EOS can be understood as Enterprise Operation System, a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture introduced to achieve performance expansion of distributed applications. Note that it is not a currency like Bitcoin and Ethereum, but a token released based on the EOS software project, called Blockchain 3.0.

Characteristics of blockchain (EOS)

1. EOS is somewhat similar to Microsoft's Windows platform. It supports multiple applications by creating a developer-friendly blockchain underlying platform.Run simultaneously to provide the underlying template for developing dAPP.

2. EOS solves the problems of delay and data throughput through parallel chains and DPOS. EOS can handle thousands of transactions per second, while Bitcoin has about 7 transactions per second, and Ethereum It is 30-40 transactions per second;

3. EOS has no handling fees and has a wider general audience. To develop dApps on EOS, the network and computing resources required are allocated according to the proportion of EOS owned by the developer. When you own EOS, it is equivalent to owning computer resources. With the development of DAPP, you can lease the EOS in your hand to others. From this point alone, EOS also has extensive value.

⑥ What can Mobile Cloud Object Storage EOS do?

Object storage EOS (Elastic Object Storage) is a massive space storage product provided by Mobile Cloud to customers. It has high performance, It features high reliability, security, and low cost. It provides storage services for unstructured data (pictures, audio and video, text and other format files) through the standard S3/Swift interface, allowing users to manage and access data anywhere through the Internet. needs.
Simply put, it is a storage tool. However, compared with common storage tools, Mobile Cloud's object storage EOS has the following features:
1. Bucket management
Supports the creation and deletion of buckets (containers for storing objects), and sets bucket access permissions , access rules, and bucket-related functional configurations.
2. Lifecycle management
Bucket-level lifecycle policies can be set to implement regular storage type conversion of files and deletion of historical fragmented files.
3. File management
It can upload and download files, set file access permissions, generate shared access links, supports multi-version control functions, and allows multiple versions of files to be saved.
4. Static website hosting
Users can upload static web pages to the bucket and implement website publishing after configuration. Simplify website building operations and reduce website operation and maintenance costs.
5. Anti-hotlinking
You can limit data access rights to certain IP segments to prevent excessive downloading of data and protect data security.
6. Monitoring
It can display usage information in two dimensions: object storage account level and bucket level, making it easier for users to understand resource usage.
7. Sub-account
Supports the creation of multiple sub-accounts to achieve data access isolation and meet guest user temporary access to object storage scenarios.
8. Image processing
Through the image processing service, users can create a variety of image styles on demand and diversify the images uploaded to the mobile cloud object storage.
9. Cross-domain access
Supports creation, modification and deletion of cross-domain access rules, allowing access and movement from different source domain namesCloud object storage resources solve the problem of browser same-origin policy restrictions.
It can be applied to multiple scenarios such as website hosting, multimedia data storage and playback, and data backup.
At the same time, the mobile cloud official website provides three product types to choose from, namely standard storage (suitable for storing frequently accessed hot data), low-frequency storage (suitable for storing data that is not frequently accessed but can be accessed quickly when needed) ) and archive storage (suitable for archived data that needs to be preserved for a long time).
I happened to see that the official website of Mobile Cloud has a one-month free trial of object storage. If you want to try it out, you can give it a try. The activity seems to be valid for a long time, but it is only for new users of the platform.

⑦ EOS development process

EOS is a blockchain underlying public chain system developed by Block.One. It is specially designed to support commercial decentralized applications (Decentralized Application). As for the design, its code is open source.

Bitcoin is called blockchain 1.0 because it opened up the world of digital cryptocurrency and took a decisive step from 0 to 1.

Ethereum is called Blockchain 2.0 because it provides a Turing-complete virtual machine that can run smart contracts, bringing unlimited possibilities.

EOS is called blockchain 3.0. Why? Two words: performance.

The positioning of EOS is exactly the slogan on its homepage:

English: The most powerful infrastructure for decentralized applications.

Chinese: The most powerful decentralized application infrastructure.

EOS hopes to be an enhanced version of Ethereum, a high-throughput smart contract platform.

Although Ethereum is fully functional, due to its design choices, the block generation speed of 15 seconds means that the transaction throughput is far from reaching the level of large-scale practicality, only about 30~40TPS (transactions/second) . EOS has chosen a different technical route, aiming to achieve a considerable million TPS - considering that Visa's actual processing speed is only 1700TPS, this goal is indeed quite attractive.

The consensus mechanism of EOS

The reason why the throughput of Bitcoin and Ethereum is so low is that it is subject to the application scenarios envisaged and the consensus mechanism chosen for that scenario - this Both assume that the environment in which the system runs is completely untrustworthy, so they both adopt the consensus mechanism of Proof of Work.

Consensus, as the name suggests, is when everyone reaches a unified understanding of something - for blockchain, something refers to the confirmation of a transaction - any node that wants to submit a transaction must Everyone needs to agree.

The PoW mechanism currently used by Bitcoin and Ethereum was designed by the legendary Satoshi Nakamoto. In this mechanismIn order to obtain accounting rights and digital currency rewards, miners need to keep mining to find compliant hash values, and confirm and package transaction data through consensus on hash values. PoW has no entry threshold, and any node has equal rights to participate in accounting - of course, the probability of winning is related to computing power:

The price of RAM is based on Banco ( Bancor) algorithm, that is to say, it is regulated by market supply and demand: if the supply of RAM exceeds demand, more EOS tokens are needed when buying RAM, and more EOS tokens can be obtained by selling RAM at this time.

Memory consumes resources and cannot be redeemed, but can only be bought and sold. Take the issuance of coins on EOS as an example. Currently, issuing coins requires 20M of memory, and one EOS can buy 20KB. According to the current storage price, it takes 1,000 EOS to send one coin. This is a necessary source of EOS memory consumption.

⑧ What is EOS

The full name of EOS "Enterprise Operation System" is a high-availability public chain, and transactions can be confirmed in almost one second.
Bitcoin was originally born to implement a peer-to-peer cryptocurrency system. On this basis, Ethereum implemented a Turing-complete virtual machine to make the blockchain a computing platform, and EOS was born to be a computing platform. system. Smart contracts on EOS are similar to various programs on our computers, and even the EOS token itself is a contract.
Generally, when we use a certain cryptocurrency, we need to have an address. When collecting money, others only need to transfer money to this address. However, there is no concept of address in EOS. Users who want to use the EOS blockchain must create an account on the EOS chain before they can use it.

Creating this account is actually a contract transaction, which requires a usable account to create. This is also a factor that makes the threshold for using the EOS blockchain relatively high, because at the beginning of EOS’s launch, There are few accounts available, and there is a lack of tools (such as wallets) for users to create accounts.

Moreover, creating an EOS account requires consuming RAM. According to the current soaring price of RAM, creating an EOS account requires several EOS, which is considered very expensive.
