⑴ What does eos mean?

EOS means commercial distributed design blockchain operating system.

EOS is a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture introduced to achieve performance expansion of distributed applications. It is not a currency like Bitcoin and Ethereum, but a token released based on the EOS software project, called Blockchain 3.0.

EOS uses the DPoS consensus algorithm and other technical means to achieve millions of transaction requests per second and will be able to support thousands of commercial-grade DAPPs. EOS is just a blockchain infrastructure. Developers can freely create public chains on EOS. Chains will not affect each other's resource use, and there will be no large-scale network congestion caused by individual application resource consumption.

The main features of EOS:

1. EOS is somewhat similar to Microsoft’s windows platform, by creating a developer-friendly blockchain underlying platform , supports multiple applications running at the same time, and provides underlying templates for developing dAPPs.

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.

⑵ What is blockchain? In addition to food traceability, what other common applications does blockchain have?

Save production and distributor costs, use blockchain technology and material Networking can realize automated data collection and storage, reducing labor investment and other equipment investment; in addition, the application of blockchain technology and the Internet of Things can help manufacturers and distributors reduce various expenditures and reduce the price of agricultural products, thereby realizing customer satisfaction. profit.

The key to blockchain technology is a distributed digital ledger that can store all types of information, including cryptocurrency transactions, NFT usage rights, and DeFi blocks chain.

Although any traditional database system can store this information, digital currency is unique in its complete blockchain technology. In contrast to systems maintained in a core organization by central administrators (such as Excel spreadsheets or bank database systems), blockchain databases have many identical copies stored on multiple computers that exist on the network, but these independent electronic Computers are called connection points.

The name "blockchain technology" is not a whim. Data ledgers are generally described as "chains" composed of separate "data blocks". When new data is imported into the Internet, a new "block" will be created and added to the "chain", which involves all nodes updating their version of the blockchain ledger so that they are the same.

⑶ How to remove the fake and preserve the true in the blockchain

The era of barbaric growth is coming, which is both an opportunity and a challenge for the blockchain.
In recent years, blockchain has gradually developed into a hot topic. Especially in 2018, which has just entered, the concept of "blockchain" has appeared frequently in the business world. So what exactly is blockchain? Why is Liang Shiqiao, an entrepreneur and capitalist, so concerned?
Previously, many people thought that there was an equal relationship between blockchain and Bitcoin, but after in-depth understanding, they discovered , this is a wrong idea. To put it bluntly, blockchain is a distributed ledger, and Bitcoin uses blockchain technology to improve itself.
Blockchain is a decentralized technology, just like a country. In this country, the distribution of data information and rights between people is the same, and there is no falsification of data. It is possible and impossible to lose. The two major advantages of sharing mechanism and value exchange are the power of blockchain.
Is blockchain becoming a new trend after Bitcoin?
As early as 2008, Satoshi Nakamoto published an article titled "Bitcoin: A Peer-to-Peer Electronic Cash System" on the forum. The concept of blockchain was first proposed in the article.
However, there have been constant controversies since the emergence of Bitcoin. The loudest opponents are Warren Buffett and Robert Shiller. Buffett, known as the "Stock God", made it clear that Bitcoin "will definitely not have a good outcome in the end." Of course, there are also voices of support. Wall Street tycoon Jamie Dimon believed that Bitcoin was a scam a year ago, but now he has overturned his previous view and believes that blockchain is real. Regardless of the final outcome, the development of Bitcoin has attracted more and more attention in recent years.
In 2013, Bitcoin skyrocketed 100 times from being worthless at the beginning. However, in the next two years, Bitcoin showed a sharp decline again. In 2014, it fell by no less than 70%. In 2015, it fell by more than 20% again. By 2016, Bitcoin entered an upward stage, and by 2017, it was resurrected. This roller coaster development not only brought losses to people, but also attracted more attention to the blockchain.
People love and hate Bitcoin. When Bitcoin becomes popular, as the core foundation and underlying architecture of Bitcoin, blockchain is gradually attracting people's attention. Blockchain is the key to supporting the formation of Bitcoin. The reason why Bitcoin can achieve such results is inseparable from the blockchain. Since every transaction in Bitcoin is recorded in a block-by-block ledger, this ledger is decentralized, and the blockchain serves as the "role" of the Bitcoin ledger. Bitcoin can be said to be the best application of blockchain, bar none.
Some time ago, Xue Manzi acquired this domain name, and in this transaction, Xue Manzi used Bitcoin to complete the transaction.The incident caused quite a stir in the circle. Recently, the frequency of use of Bitcoin in domain name transactions has been increasing, and what caused this phenomenon is the importance that capitalists attach to blockchain.
Previously, blockchain was only used by Bitcoin, but in recent years, as Bitcoin gradually spreads around the world, blockchain has begun to be applied in various projects, such as Ant Financial, JD.com, Internet and Tencent have gradually begun to apply blockchain technology. The authenticity and non-tampering nature of blockchain makes its application in other projects such as public welfare even more convenient. For example, Ant Financial has applied blockchain technology in "Hearing-impaired Children Regain a New Life", Tencent has launched the "Public Welfare Tracing Chain" and so on. By 2017, blockchain has begun to be widely used and has gradually formed a new trend.
The era of barbaric growth is coming, which is both an opportunity and a challenge for the blockchain
There is this sentence in Dickens's "A Tale of Two Cities": "It was the best of times, it was the worst of times, it was wisdom. This is an era of stupidity. People have all kinds of things in front of them, and people have nothing in front of them; people are going straight to heaven, and people are going straight to hell." Just like the blockchain, if you do it well, you will be the pioneer who participates in the changes of the times. Do it poorly and you will perish.
Today, the blockchain is facing such a situation: the rapidly developing society and the emerging enterprises have brought many possibilities to the blockchain, which has attracted more attention and accelerated the development of the blockchain industry. The enterprise application of blockchain may usher in a new era.
Blockchain can be roughly divided into three types: private chain, alliance chain and public chain. Each blockchain corresponds to different scenario applications. The most critical difference between these blockchains is the degree of decentralization. Limit scope. Blockchain is also widely used due to its distributed recording of data, data cannot be tampered with, and is open and transparent. Different from the transmission of information on the Internet, the blockchain is the transmission of value, which can be said to be an upgrade of the Internet. Based on this, blockchain is considered to be another central technology that is very likely to cause a disruptive revolution after steam engines, electricity, and the Internet.
But the blockchain is not omnipotent:
Firstly, there is delay in the blockchain. Take transactions in Bitcoin as an example. Its effectiveness is affected by network propagation and takes ten minutes to complete. Be informed and recognized;
Secondly, the blockchain itself does not have the two functions of "modify" and "delete", which makes post-processing very troublesome if errors occur when recording data.
In addition to its own limitations, in the face of the complex enterprise market, blockchain, which has gradually become the new darling of the market, has also led to a series of "accidents" such as "coin speculation" and "pseudo-blockchain". .
In September last year, the country had banned the trading of virtual currencies such as Bitcoin and ICO, but the strong money-making effect has brought the currency speculation boom back to people's attention. First, Xunlei launched Wankecoin (now called LinkToken) in October, and then Renren released the blockchain project "Renrenfang" and tokens RRcoin and KeDa launched Kodak Coin and many companies entered the blockchain to issue tokens, which made the phenomenon of "coin speculation" once again sweep across.
Currently, there is no shortage of money-making projects on the market. Companies are mixed in the blockchain application market. It is difficult for investors to distinguish the pros and cons of projects, and there are even situations where bad coins drive out good coins. In the market, "processing" of public data has become a social norm. For example, in order to attract more consumers and capitalists, companies will modify the data they publish accordingly to attract users to choose and Corporate investment.
In addition, some companies are trying to make money in the name of blockchain. After seeing the benefits brought by blockchain, some companies rushed into the game without understanding the operation of blockchain in order to be the first to enter this trend and obtain high profits; some even used blockchain gimmicks to do so. Make money wantonly and retreat quickly after obtaining high profits. This blind application of blockchain has caused some companies that really want to apply and develop blockchain to gradually withdraw from the market, while some companies that mainly focus on making money are still active in the market, which has greatly affected the development of blockchain. normal development trajectory.
Although the blockchain has the core technology to create new trends, because it is still in its infancy and is not mature enough in all aspects, it will still bring about various problems such as "coin speculation", which have become obstacles to the blockchain stumbling blocks to chain development.
Will the increase in entrants accelerate the bursting of the blockchain bubble?
Relevant data shows that from November 2015 to December 2017, the growth rate of blockchain-related occupations reached 631%. However, in this huge data, there are some companies that join the blockchain ranks with the mentality of "getting a quick buck and leaving", which disrupts the normal development of blockchain in the market and further promotes the bursting of the blockchain bubble. 's appearance.
Different from previous years, blockchain has developed very well in recent years, and its application scope has expanded to various fields such as finance, education, government, cloud computing, medical care, and insurance. As the number of entrants gradually increased, many irrationalities appeared in blockchain applications, causing batches of contestants to withdraw.
Recently, a WeChat group called "Blockchain without Sleep at Three O'Clock" has aroused heated discussion. In this group, some well-known people from the industry gathered to talk about blockchain and Bitcoin day and night. Have an in-depth discussion. Among this group of people, blockchain has basically become their “belief”. It seems that if you don’t understand blockchain, you will be eliminated by the times. This kind of blindly following the trend reflects not only people's anxiety about the development of the times, but also the market's strong demand for blockchain. Furthermore, the recent popularity of blockchain concept stocks has triggered more and more investors to enter the blockchain market, causing the blockchain market to expand rapidly and create bubbles.
Furthermore, since the blockchain is still in its infancy, there are still many aspects that need to be improved. At this time, it is tentative for companies and investors to enter the blockchain. Blockchain, a technology with revolutionary significance for the times, still needs to be gradually developed. Moving forward rashly will only put the original track on the right track.The blockchain goes further.
Regarding the understanding of the development of blockchain, Gartner consulting firm has previously analyzed relevant aspects: a new technology basically goes through five stages, namely the embryonic stage, the popular expansion stage, the bubble bursting stage, and the upward recovery. period, maturity stage. According to Gartner's analysis in 2016, blockchain is already in a period of inflated expectations. At this time, it is in a period when the bubble is about to burst, and it will take 5 to 10 years before blockchain reaches maturity. .
Will blockchain become the key to the era of change?
2017 can be said to be the year of the explosion of blockchain, with various capitals getting involved in blockchain. Although it has brought many problems to the market, the role of blockchain in market development cannot be ignored. Recently, "Three Questions about Blockchain (Economic Hotspots)", "Seizing the Opportunity of Blockchain", and "Being a Leader in the Digital Economy" published in the "People's Daily" clearly stated the impact of blockchain on various fields of the market. important role.
Issues such as delay, "pseudo-blockchain", and "coin speculation" will further attract people's attention after the blockchain bubble bursts, and more standardized market development will occur. Today, blockchain is still in its infancy. As more and more entrants enter the industry, a blockchain bubble is inevitable in the future. But after the bubble, blockchain will bring a disruptive experience to the market and usher in a new era.
Blockchain itself emphasizes "decentralization". In order to meet the ever-changing real needs, blockchain is upgrading to "multi-centering", which will completely break the data "island" and achieve comprehensive interconnection of information. situation. It can strengthen the trust security system, improve transaction efficiency, and meet the application needs of the increasingly developing era.
In short, the explosion of blockchain is inevitable. Its decentralized nature avoids the monopoly of Internet giants and brings development opportunities to many entrepreneurs and investors. But at the same time, based on blockchain, it can reduce transportation costs, is open and transparent, cannot be tampered with, has strong permeability and other properties, and is more convenient for market management. In the future business world, there will be a blockchain era that "removes fakes and preserves authenticity" .

⑷ The currency transferred to Binance Exchange does not arrive in the account

The reason why the currency transferred to Binance Exchange does not arrive is due to blockchain congestion, delay and other reasons. Blockchain assets are divided into three steps: proposal, block confirmation, and accounting.
1. A successful transfer means that the platform or wallet that withdraws the currency has performed a transfer operation.
2. Complete the corresponding block confirmation. Blockchain congestion, delays and other situations will cause the user's digital currency to be delayed in completing all confirmations.
3. After confirmation to the platform, the account will be completed as soon as possible.

⑸ Times have changed, what is the core of the blockchain economy?

Since the birth of Bitcoin, more than 1,600 virtual currencies have appeared around the world. Currency has formed a huge industrial chain ecosystem around the generation, storage, and transactions of virtual currency. But overall, the industry is still in its infancy and is still far away from the real value application area.

The core of the blockchain economy lies in the reconstruction of business logic and organizational form, so it is necessary to obtain application examples in multiple industries to demonstrate its value. This article will explore the business models of blockchain applications in various industries from the perspective of combining blockchain with industry needs.

First of all, the core of blockchain is to solve the problem of credit:

Credit is the foundation of all commercial activities and finance. The United States has implemented trusted identification since 2011, while China has implemented a real-name system to achieve supervised information dissemination. The significance of blockchain is that it has established decentralized trust from a technical level for the first time and realized a completely distributed credit system.

Secondly, blockchain solves the problem of value exchange:

Traditional networks can realize point-to-point transmission of information, but cannot realize point-to-point transmission of value. Because information is allowed to be copied, and value must be authentic and unique, it is necessary to rely on a centralized organization to achieve value transfer. Blockchain perfectly solves this problem and provides a method to realize point-to-point transfer of value. During the value transfer process, accounting is realized by the network without relying on a centralized institution. Therefore, blockchain is expected to become the infrastructure for building new finance and the cornerstone of the future value Internet.

Application of blockchain

Currently, there are two main modes of blockchain application:

1) Native type Blockchain applications: directly based on decentralized blockchain technology, realizing applications such as value transfer and transactions, such as digital currency;

2) "Blockchain+" model: combining traditional scenarios with Combined with the underlying protocol of the blockchain to improve efficiency and reduce costs. It is expected that the application of blockchain in various industries will be dominated by the second model.

Blockchain has five core attributes, namely: transaction attributes (value attributes), certificate attributes, trust attributes, intelligence attributes, and traceability attributes. The above core attributes are combined with the needs of the industry to solve the industry's pain points and become a business model for blockchain applications in various industries.

Blockchain + Bank

1. Cross-border payment

Cross-border payment is a pain point that has long plagued the banking industry. Traditional cross-border payment methods include two major categories: one is online payment, including electronic account payment and international credit card payment, which is suitable for retail small amounts; the other is the bank remittance model, which is suitable for large-amount transactions; both have payment cycles Long, high fees, low transaction transparency and other issues. Especially in recent years, with the rise of cross-border e-commerce, convenient, fast, safe and low-cost cross-border payment has become an urgent need for the industry.

The role of blockchain:

Blockchain goesThe characteristics of intermediation and open and transparent transactions, without the participation of third-party payment institutions, shorten the payment cycle, reduce fees, and increase transaction transparency. For example, in December 2017, China Merchants Bank teamed up with Wing Lung Bank and Wing Lung Shenzhen Branch to successfully implement cross-border RMB remittances between the three parties using blockchain technology. Its clearing process is safe, efficient and fast, greatly improving customer experience.

2. Supply chain finance

The pain points in this field are the long financing cycle and high costs. Centered on the core enterprise system of the supply chain, it is difficult for third-party credit enhancement institutions to authenticate the authenticity of various relevant vouchers in the supply chain, resulting in long manual review times and high financing costs.

The role of blockchain:

Blockchain introduces consensus mechanism, existence proof, non-tampering, traceability and other features into supply chain finance, without the need for a third-party credit enhancement agency Identify the authenticity of various relevant vouchers in the supply chain, thereby reducing financing costs and shortening the financing cycle. For example, in April 2017, the listed company Yijian and IBM China Research jointly launched the blockchain supply chain financial service system "Yijian Block". The system focuses on pharmaceutical scenarios and currently has more than 30 pharmaceutical distribution companies. Successfully registered in the "Yijian Block", as of the end of July, the number of transactions had been close to 8,000, and the total investment amount exceeded 100 million yuan.

3. Digital Bills

The pain point of the digital bill industry lies in the long-standing problems of "false bills" and "one vote selling more than one", which have brought challenges to the bill financing business of the banking industry. risk.

The role of blockchain:

The existence proof and non-tampering characteristics of blockchain effectively solve the problem of false digital bills; at the same time, blockchain solves the problem of double Spending money can avoid "one ticket selling too many". For example, Shenzhen Blockchain Financial Services Co., Ltd. issues bill chain products to provide bill financing services based on blockchain to solve the bill financing needs of small, medium and micro enterprises. Cooperative banks include Ganzhou Bank, Guiyang Bank, Suzhou Bank, Shizuishan Bank, Langfang Bank, Wuhai Bank, Jilin Jiutai Rural Commercial Bank, Yaodu Rural Commercial Bank, Shenzhen Rural Industry Bank, Weifang Bank, Zhongyuan Bank, etc. In addition, Zheshang Bank, JD Finance, Hang Seng Electronics, HNA, etc. are also verifying blockchain digital bill services.

Blockchain + Securities

1. Asset Securitization

Asset securitization uses future income as a guarantee to obtain current financing. The pain points in this field are: there are many participating entities, many operating links, low transaction transparency, information asymmetry, and the authenticity of the underlying assets cannot be guaranteed.

The role of blockchain:

Blockchain introduces attributes such as existence proof, non-tamperability, and consensus mechanism for asset securitization, which can monitor the true situation of assets in real time and solve the problem of It solves the problem of trust of all parties in the transaction chain in the underlying assets. Various assets such as equity, bonds, notes, income certificates, warehouse receipts, etc. can be integrated into the blockchain and become digital assets on the chain, improving asset circulation efficiency and reducing costs. For example, in May 2017, Internet Finance and partners including Baiqian Leasing and Huaneng Trust jointly issued an asset securitization ABS project supported by blockchain technology, with an issuance scale of 424 million yuan.

Blockchain + Insurance

1. Insurance business

The insurance industry has problems such as information asymmetry and lack of trust between customers and insurance institutions: Users It is difficult to choose an insurance product that suits you, and insurance institutions face the risk of insurance fraud.

The role of blockchain:

The decentralized, open, transparent, and traceable characteristics of blockchain establish a good communication channel between insurance institutions and users; insurance targets Information is managed uniformly on the blockchain and cannot be tampered with, helping insurance institutions avoid the risk of insurance fraud; at the same time, smart contracts can improve work efficiency and reduce costs. For example, French insurance giant AXA is using the Ethereum public blockchain to provide automated flight delay compensation for air travelers. If the flight is delayed for more than 2 hours, the "smart contract" insurance product will automatically pay claims to passengers.

2. Credit information management

The pain point in this field is that credit information agencies have limited data collection channels and lack of data sharing, making it difficult to accurately characterize the credit status of individuals or institutions; in addition, There is also the issue of how to protect user privacy during the data collection process.

The role of blockchain:

The blockchain has the characteristics of trustlessness, consensus, and non-tampering. At the technical level, it ensures that effective protection of user privacy can be achieved. Limited, controllable credit data sharing and verification. For example, Ping An's blockchain credit reporting business is now online. In addition, domestic startups such as Shanghai Juzhen, LinkEye, Bubi Blockchain, etc. are also exploring joint credit reporting and safe certificate deposits.

As a basic technology, blockchain has great application value in many industries with distributed processing, peer-to-peer transactions, and rapid establishment of trust relationships. Its core is to solve the credit problem and realize the point-to-point transmission of value. Therefore, it is considered to be the cornerstone of the future value Internet.

The core of the blockchain business model is to use the innovative attributes introduced by the blockchain and combine it with traditional industry applications to realize the reconstruction of business logic in order to create new application scenarios or improve efficiency. cut costs.

Blockchain will also extend to all areas of social life: Blockchain solves problems such as the management, transaction, and transfer of digital assets, and therefore will play an important role in the wave of asset digitization, such as supply Applications such as chain management, data services, asset management, public services, and the Internet of Things are gradually being implemented in various fields. "Blockchain+"is becoming a reality.

⑹ New trends in the future of global supply chains 1, board the express train of "blockchain" technology

The outbreak of the pandemic has reduced the global Movement of goods. Cargo sluggishness at ports is a particular side effect of the COVID-19 pandemic, a supply-demand mismatch that has left manufacturers in various countries waiting months to produce or assemble raw materials and components.

Consumer demand is revitalized as COVID-19 lockdowns are lifted and government relief spending begins. However, supply chains cannot be synchronized, and production lines will slowly return to full operating capacity after being closed or curtailed.

In the automotive industry, reduced supplies of plastic components, petrochemicals and semiconductor chips used to control power windows, airbags and dashboards have led most manufacturers to production capacity decreased. The chip shortage has also halted production of computers, smartphones, medical equipment, vacuum cleaners, refrigerators and smart devices.

Like a flurry of activity, consumer demand suddenly stopped as the pandemic hit, and then when the economy came back to life, government largesse added additional As cash was put into people's pockets, consumer demand suddenly returned.

But when demand plummeted early in the pandemic, supply chains slowed to a trickle. When demand picks up, it takes suppliers longer to catch up, leading to months and months of delays. Now, supplies are being shipped, but there are only so many containers available.

Shipments at the port are also delayed due to a shortage of longshoremen and truck drivers. Once container ships are unloaded at congested ports, the goods are transported by rail and heavy semi-finished goods to factory loading docks, distribution centers and retail stores. But like other businesses, trucking companies are finding it difficult to predict demand and have significantly scaled back hiring. Demand for truck drivers is soaring now, but many found alternative employment in the first months of the pandemic.

Vertical vertical integration: A solution to supply chain problems?

Acquiring a small supplier whose production capabilities can be fully absorbed by an acquiring company is a move that many companies are currently considering. Such purchases seem most likely to become common transactions, based largely on stock and employment contracts and cash incentives, each tying the entity's management to ongoing operations and changing ownership.

After World War II and the Great Depression, well-educated workersPower and advanced infrastructure catapulted the U.S. economy to a leadership position unsurpassed in 80 years.

The pandemic has prompted some company executives to readjust the supply chain management playbook. The biggest lesson companies have learned from the supply chain crisis is the need to improve sales forecasting.

When a black swan event occurs, your idea of ​​making predictions based on historical trajectories has little value. The CFO must evaluate real-time demand data and work closely with procurement and sales. Daily sales data need to be compared with purchasing data. Finance can then decide where capital must be allocated to maintain supply chain resiliency.

In the future, CFOs may be able to use blockchain technology to assess in real time whether suppliers and shippers can keep up with demand. Within the blockchain, participants will record transactions, pricing, dates, locations, quality, certifications and other data needed to manage the supply chain. Blockchain platforms will provide this visibility.

Blockchain can also be used to create "zero-latency" supply chains. Instead of large numbers of suppliers that are not tightly connected or loosely coordinated, they can now be digitally interconnected in centralized supply networks. Companies may be reluctant to join such a network due to concerns about data control, security and privacy, but users can manage access to information through data encryption.

A few years ago, there was a lot of interest in blockchain solutions, but then it fell off the radar. Due to the current market chaos, Americans have begun to study it again.

Due to rapidly rising demand and concerns about the impact of delayed deliveries on competition. In the United States, some large companies are now interested in using blockchain solutions again, showing great interest in supplier tracking and traceability, especially for logistics elements.

The global supply chain is disrupted and logistics costs continue to soar. How should the manufacturing industry break through?

Tianmu Academy, tomorrow will be better!

⑺ What currency is EOS

What currency is EOS? Virtual currencies have become very popular recently. Many friends have begun to pay attention to virtual currencies. Recently, EOS, a virtual currency, has become increasingly popular. Many friends still don’t know what kind of currency it is, so let’s follow Let’s take a look together.
What currency is EOS?
EOS Introduction
EOS is called Blockchain 3.0, which is different from Bitcoin.
Bitcoin does not rely on the issuance of a specific currency institution. It is generated through a large amount of calculations based on a specific algorithm. The Bitcoin economy uses the public in the entire P2P network.The distributed database composed of Biduo nodes confirms and records all transaction behaviors, and uses cryptographic design to ensure the security of all aspects of currency circulation.
P2P’s decentralized features and algorithm itself ensure that currency value cannot be artificially manipulated through mass production of Bitcoins. Design based on cryptography allows Bitcoin to be transferred or paid only by real owners. This also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between Bitcoin and other virtual currencies is that its total quantity is very limited and it is extremely scarce.
eos is a token on eth. It is an operating system-like blockchain architecture platform developed under the leadership of blockchain wizard BM (Daniel Larimer), aiming to achieve performance expansion of distributed applications.
EOS provides accounts, authentication, databases, asynchronous communication, and program scheduling on hundreds of CPUs or clusters. The final form of this technology is a blockchain architecture that can support millions of transactions per second, while ordinary users do not need to pay usage fees.
Main features of EOS
1. EOS is somewhat similar Based on Microsoft's Windows platform, by creating a developer-friendly blockchain underlying platform, it supports multiple applications running at the same time and provides underlying templates for developing dAPPs.
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 has 30 transactions per second. -40 pens.

⑻ What are the relevant terms about the blockchain industry

1. Utility token

A utility token is a utility token that can serve as a token for using a specific service. right.

Examples of term usage

Utility tokens are predicated on using a service.

Details

You can settle the price of goods and meals instead of cash, or you can access it by having cloud storage. For utility tokens, classification of audit reports is not required.

6. Public chain

A public chain is a highly "public" blockchain where anyone can freely participate in the network.

Examples of term usage

As an infrastructure project that mediates the exchange of data between blockchains, a mechanism for exchanging data on a public blockchain will be established.

Details

In a blockchain used to record transaction information for crypto assets (virtual currencies), this is a mechanism used by an unspecified number of participants to Consensus builds transaction information without a specific governing entity. It is very safe to prevent forgery of transaction information, but it requires a lot of calculations, so its disadvantage is that it takes a long time to complete the transaction when there are many participants.

7. Scalability problem

Scalability problem refers to the "scalability" problem that delays transaction processing.

Term usage indicationExample

Spiking gas prices have highlighted Ethereum’s scalability issues.

Details

Due to the nature of blockchain, there are processing delays due to the limited amount of transaction data that can be written in a block. Sending money can take a long time, which results in higher transaction fees. Bitcoin, the first cryptocurrency to be created, has been recognized as a special problem, but efforts to solve it have been implemented, such as leveraging other technologies such as the Lightning Network and developing new blockchains.

8. GAS fee

GAS fee is the (network) transaction fee on the Ethereum blockchain.

Examples of term usage

This week, there were multiple cases of high gas bills being paid on the Ethereum blockchain despite small remittances.

Detailed description

The user-specified amount of GAS fee is a secondary reward. The virtual currency Ethereum (ETH) is used for payments. Because transactions with higher fees are processed first, GAS fees may increase as the number of transactions increases.

9. Liquidity Mining (Liquidity Mining)

Considering the provision of liquidity (currency pairs), liquidity mining refers to the granting of governance tokens in addition to interest to attract those who implement yield checks and balances .

Examples of term usage

Liquidity mining is accelerating and profitable.

Details

In liquidity mining, by storing a specific asset in a liquidity pool and providing liquidity that traders can buy and sell, the swap fee at the time can be used as Income earned. These liquidity mining originated from the largest decentralized exchange "Uniswap", and many liquidity mining contracts were born, such as Curve Finance and Balancer.

10. DeFi (Distributed Finance)

DeFi (Decentralized Finance) refers to financial services or systems that utilize blockchain and are provided without a central administrator.

Examples of term usage

Since June 2020, the DeFi market has developed rapidly.

Details

Abbreviation for "decentralized finance". Financial services provided by DeFi include issuing stable coins, lending currencies, and cryptocurrency exchanges. Many platforms use the Ethereum blockchain.

11. PoS (Proof of Stake)

PoS is a consensus algorithm that gives you the right to approve and generate new blocks based on the percentage (stake) of the virtual currency you own.

Examples of term usage

Ethereum co-founder Vitalik Buterin said that moving ETH’s consensus algorithm from PoW to PoS will improve security and scalability.

Details

Abbreviation for Proof of Stake. You can also consider the holding period of the virtual currency. It was born as an alternative to the “Proof of Work (PoW)” consensus algorithm, which requires high performancepowerful computers to approve transactions and consume large amounts of energy. If approved, you can receive newly issued virtual currency as a reward.

12. dApps

dApp is an application developed using open source blockchain.

Examples of term usage

South Korea’s largest Samsung Electronics app store “Galaxy Store” has started using Tron’s blockchain to process dApps.

Details

Abbreviation for "decentralized application", also known as "decentralized application" in Japanese. A major feature is that there is no centralized administrator. The most popular is the Ethereum blockchain, which is developing applications such as gaming and decentralized exchanges (DEX).

⑼ What are the disadvantages of blockchain

Blockchain has many advantages and obvious disadvantages.

1. Cannot be tampered with or revoked
This is both an advantage and a disadvantage. There is no regret medicine in the blockchain. There is almost nothing you can do about the data changes in the blockchain. This is mainly reflected in: If the transfer address If you fill it in incorrectly, it will directly cause permanent losses that cannot be reversed; if you lose the key, it will also cause permanent losses that are irreversible. In reality, if you lose your bank card or forget your password, you can still go to a bank branch and your money will still be there.

2. The transaction ledger must be made public
The blockchain is distributed. On the public chain, making a document means that everyone has a complete ledger, and due to the block Calculating balances on the chain, verifying transaction validity, etc. need to trace every account, so the transaction data is open and transparent. If I know someone's account, I can know all his wealth and every transaction. , there is no privacy at all.

3. Performance issues associated with larger data
As mentioned earlier, everyone has a complete ledger, and sometimes it is necessary to trace every record, so as time goes by , when the transaction data is very large, there will be performance problems. For example, when using it for the first time, you need to download all the transaction records in history to work properly. In order to verify that you actually have enough money for each transaction, you need to trace back the history of each transaction to calculate it. balance. Although performance problems can be alleviated through some technical means (such as indexing), the problem still clearly exists.

4. Delay of blockchain
There is delay in blockchain transactions. Taking Bitcoin as an example, the validity of the currently generated transactions is affected by network transmission, because it requires Before most nodes on the network learn about this transaction, it will have to wait until the next accounting cycle (Bitcoin controls this to about 10 minutes), that is, the transaction must be recognized by most nodes. It is also affected by a small probability event, that is, when two or more nodes compete for accounting rights on the network at the same time, then two or more blockchain branches will be generated in the network. At this time, which branch records the data? is valid, you have to wait for the next accounting cycle, and finally the finalDetermined by long blockchain branches. Therefore, the transaction data of the blockchain is delayed.

Blockchain, as a conceptual innovation, can have a disruptive impact in specific fields. Faced with the advantages and disadvantages of blockchain, what needs to be done is to maximize its strengths and avoid weaknesses, and make the best use of it. Therefore, whether blockchain can become the underlying technology of a new generation of financial infrastructure is still a question.

⑽ What to do if the blockchain network is congested

1

What is network congestion

Usually refers to a type of network Fault phenomenon: An office LAN computer uses an ADSL Modem+HUB with routing function to share the Internet. When there are fewer people online at the same time, the network is relatively smooth. When more people are online, the network will be intermittently connected, and the HUB's Collision indicator will flash continuously.

In blockchain applications, whether it is digital currency, smart contracts, decentralized trading systems, etc., their networks are composed of independent nodes. Various operations in the network, such as transfer transactions, changes in contract status, etc., will be broadcast to the network in the form of transaction data, and will be packaged into new blocks by miners as part of the main chain to ultimately confirm all these operations.

When there are many nodes and a lot of usage, a large number of transactions will not be packaged within the normal expected time, because they are all congested in the network, waiting for confirmed transaction data Usually maintained in the node's memory pool. This is the congestion of the blockchain.

How network congestion occurs

The current Bitcoin block size is 1M, and it can only process approximately 7 transactions per second. As the transaction volume continues to grow, the Bitcoin network has become difficult to confirm transfer transactions quickly, and the blockchain network often experiences congestion.

At the peak, there was a backlog of tens of thousands of transactions on the blockchain network. Some transfer transaction fees were as high as dozens of dollars. When the network was congested, transactions even took several days to be packaged.

In fact, this problem exists for every type of blockchain application, causing users to constantly complain about transaction delays, but it also proves the widespread application and user experience. increase in quantity.

So what should we do when these problems occur?

How to solve network congestion

There are only the following solutions.

The first type is expansion to improve processing capabilities.

The second type is to intercept traffic and limit the number of blockchain packages.

By combining the above two methods.

Researchers at the University of Sydney have developed aA new blockchain system can achieve a throughput of 440,000 transactions per second in 100 machines, while Visa's transaction processor per second is 56,000. By comparison, Bitcoin is limited to 7 transactions per second and the Ethereum blockchain is limited to 20 transactions.

After the JadeChain public chain system is launched, it will completely solve the network congestion problem in JADE ecological applications.
