Ⅰ The blockchain industry is ushering in a new trend in the market. What are the bottlenecks in the development of the blockchain industry?

Blockchain technology is a new distributed The infrastructure and computing paradigm that enables the sharing, replication and authorization of distributed ledgers. It has the characteristics of multi-point consensus and is difficult to tamper with. It solves the problem of how to enable cross-institutional trust transactions in business networks, connecting all parties involved in financial services, and brings challenges of breaking down data silos and improving data quality. It has the potential advantages of security and lower transaction costs. Enhance risk control capabilities and have broad application prospects in the financial field. The blockchain industry is ushering in a new market trend, and there are some bottlenecks in the development of the blockchain industry. Only by breaking through these bottlenecks can we usher in the spring of blockchain. bring better development.

Finally, the development of blockchain technology will bring certain network security issues. We must pay attention to and solve information security and network security issues. Blockchain technology is not inherently secure. Any software system inevitably has defects and vulnerabilities, and will face attacks from the Internet. Poorly designed and poorly managed blockchain systems can be vulnerable to attack. In applications in the financial industry, data is an asset, so we should have a comprehensive understanding of the security of the blockchain, and first put security design and self-control first to avoid the occurrence of Bitcoin theft.

II What are the advantages of blockchain technology

Recently, many friends have come to ask questions related to blockchain, such as the specific advantages of blockchain and why they should invest in blockchain. , what benefits can it bring? Is it not allowed to invest in real estate and wait for appreciation? Is it not allowed to invest in mature markets such as stocks and bonds? Why invest in the newly emerging blockchain? What is the investment value of blockchain? ? Waiting for a series of questions, I have made the following summary, which basically summarizes the answers to most related questions:

Blockchain Advantages

Blockchain is regarded as an important part of the fourth industrial revolution. We all know that every industrial revolution will bring about leaps and bounds in human productivity. The history of human development is actually the history of one step in productivity progress

< p>It can be summarized into the following four aspects:

1. Blockchain has good market prospects; as an emerging technology, blockchain is recognized by many professionals including investors. In 2020, The market value is expected to be approximately US$60 billion, and the value of blockchain in the global market is expected to reach US$20 million in 2024. The considerable market prospects of blockchain are obvious.

2. The cost of blockchain is low; compared with centralized models such as credit card payment and stock trading that rely on third-party intermediaries, the decentralized distributed structure of blockchain saves investors It eliminates high handling fees and transaction fees, saves investment costs, and improves transaction processing efficiency.

3. Blockchain is more secure and stable; traditional centralizationThe model often faces serious credit crises, but since every transaction in the blockchain is tracked and permanently recorded by the distributed public account book, the phenomenon of forgery is greatly reduced, and losses caused by third-party credit problems are avoided. Provides security to investor transactions.

4. The programming attributes of the blockchain are more standardized; traditional market investors often affect their returns due to confusion in the market level, while the programmability of the blockchain makes the market level clear and clear, which can Innovative technologies that change people's lives.

I hope it can help you solve related problems. For more details or if you have any questions, please feel free to ask or discuss!

III Advantages of Blockchain Technology

The main thing is to change the data without changing it. This is the biggest advantage.
The blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.
Among them, the data layer encapsulates the underlying data blocks and related data encryption and timestamp technologies; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of blockchain

IV Advantages of blockchain technology

Sharing source:

p>

“Blockchain is a shared distributed database technology. Its advantages are mainly reflected in the three aspects of distributed decentralization, trustless system and non-tampering and encryption security.”

1. The meaning of blockchain technology

Blockchain technology is a technology that uses a decentralized consensus mechanism to maintain a complete, distributed, and non-tamperable ledger database. Technology that enables participants in the blockchain to implement a unified ledger system without establishing a trust relationship. Blocks are public ledgers and are maintained at multiple points; chains are stamped with timestamps and cannot be forged. Blockchain is essentially a technology that values ​​security and credibility over efficiency.

There is a database behind all current systems, which is a big ledger. Then who will keep this ledger becomes very important. Now it’s whoever owns the system who keeps the accounts. Each bank’s account books are kept by each bank, and Alipay’s account books are kept by Alibaba. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are new transaction data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write the recorded content to the ledger, and Send the contents of the ledger during this period to all other people in the system for backup. In this way, everyone in the system has a complete ledger.

Therefore, these data will become very safe. A tamperer needs to modify more than half of the system node data at the same time to truly tamper with the data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system. Therefore, it can be considered that blockchain technology is a way for all people to participate in accounting, and it will bring about innovation in accounting methods.

2. Technical advantages of blockchain

1. Distributed decentralization

Since every node and miner in the blockchain must follow the same Accounting transaction rules, and this rule is based on cryptographic algorithms rather than credit, and each transaction requires the approval of other users within the network, so the decentralized trading system does not require the endorsement of a third-party intermediary structure or trust organization.

At present, both traditional trading systems and third-party trading systems are based on central account books. The central account books play the role of information custodian, and each transaction requires a third party. Endorsed by intermediaries or trust institutions, this is a centralized trading network.

2. No need to trust the system

In the blockchain network, through the self-restraint of the algorithm, any malicious behavior that deceives the system will be rejected and suppressed by other nodes. Therefore, the area The blockchain system does not rely on the support and credit endorsement of a central authority.

In traditional credit endorsement network systems, participants need to have enough trust in the central organization. As the number of people participating in the network increases, the security of the system decreases. Contrary to the traditional situation, in the blockchain network, participants do not need to trust anyone, but as the number of participating nodes increases, the security of the system increases, and the data content can be fully disclosed.

3. Non-tampering and encryption security

The blockchain adopts a one-way hash algorithm, and each newly generated block is strictly advanced in linear order according to time, and time is irreversible. Due to its nature, any attempt to intrude and tamper with data information in the blockchain can be easily traced, leading to rejection by other nodes, thus limiting related illegal activities.

IV What are the advantages of blockchain

Decentralized, non-tamperable, convenient and efficient.
Blockchain is a distributed ledger technology that has the following advantages:
1. Decentralization: Blockchain is a distributed system that does not rely on any central organization or individual. This makes the blockchain more secure and stable, making it less likely to be destroyed or attacked.
2. Untamperable: Blockchain uses cryptography technology to ensure the security and reliability of data. Once the data is written to the blockchain, it cannot be tampered with. This makes blockchain very suitable for recording important transaction records or other data.
3. High efficiency: The distributed architecture of the blockchain enables it to process a large number of transactions quickly and does not requireRely on any centralized institutional coordination. This makes blockchain very suitable for large-scale financial transactions or other data processing tasks.
4. Privacy protection: Blockchain can use anonymous accounts or other technologies to protect users' privacy, so that users do not need to worry about the leakage of their personal information when using the blockchain.
In general, blockchain has the advantages of decentralization, non-tampering, high efficiency, and privacy protection, so it has been widely used in finance, logistics, medical and other fields.

VI Advantages of Blockchain Technology

1. Decentralization

Due to the use of distributed computing and storage, there is no centralized hardware or management organization , the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.

2. Openness

The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone and anyone can The interface queries blockchain data and develops related applications, so the entire system information is highly transparent.

3. Autonomy

The blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to trustlessly The free and safe exchange of data in the environment changes trust in "people" to trust in machines, and any human intervention has no effect.

4. Anonymity

Since the exchange between nodes follows a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself) ), so the counterparty does not need to disclose its identity to make the other party trust itself, which is very helpful for the accumulation of credit.

Outstanding advantages:

Information cannot be tampered

Once the information is verified and added to the blockchain, it will be stored permanently unless it can be controlled at the same time More than 51% of the nodes in the system, otherwise modifications to the database on a single node will be invalid, so the data stability and reliability of the blockchain are extremely high.

(6) Blockchain technology has no advantages. Further reading:

Blockchain originated from Bitcoin, which marked the starting point of the last financial crisis. Two weeks after the collapse of Mann Brothers, on November 1, 2008, a person claiming to be Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", explaining the encryption technology based on P2P network technology. Technology, timestamp technology, blockchain technology, etc. are the architectural concepts of electronic cash systems, which marks the birth of Bitcoin.

Two months later, the theory came into practice. On January 3, 2009, the first Bitcoin genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

In recent years, the worldThe world's attitude towards Bitcoin has been ups and downs, but blockchain technology, one of the underlying technologies of Bitcoin, has received increasing attention. In the formation process of Bitcoin, blocks are storage units one by one, recording all communication information of each block node within a certain period of time.

The links between each block are realized through random hashing (also called hash algorithm). The latter block contains the hash value of the previous block. With the expansion of information exchange, a Blocks are continued one after another, and the result is called a blockchain [3].

Ⅶ Do you want to know what the specific advantages of blockchain technology are?

Mainly Decentralization, this is the biggest advantage. I have seen this on the official website of Hashidon Blockchain Business School, which is transparent and traceable, open, consensus and anonymity.

Ⅷ After more than ten years, the blockchain is still tepid. Has it failed?

Almost everyone, even those who are skeptical about tokens, have concerns about blockchain technology. A positive view, because it has the potential to change the world. However, it has been 10 years since the advent of blockchain technology, and we still have not really used blockchain technology. Some people say that Bitcoin is based on blockchain technology , so the main use of blockchain is as a payment system, or as it develops, as a store of value.

Other uses of blockchain, for example, as a distributed The trading platform serves as a new currency, smart contract, distributed storage, authenticity verification and immutable distributed ledger. However, although these have been tried, there is no real application.

< /p>

Smart contracts are an interesting phenomenon. Founder Vitalik Buterin aims to create a global computing network that can completely eliminate the need for a centralized third party. This is undoubtedly great in the modern world. However, smart contracts still have a long way to go. The DAO fiasco proved that smart contracts can still be fooled, or should we say, smart contracts are sometimes too smart for them.

However, as As IC0s continues to use smart contracts as the basis of its business, it proves that blockchain still has hope in this aspect. Whether it can play a major role in these fields remains to be seen.

There are many such examples. For example. There is no doubt that it can be deduced that blockchain technology can be integrated into almost all sectors of modern life (including those mentioned above). However, it has been almost 10 years since the actual birth of blockchain technology, and no field has yet taken advantage of it. Blockchain technology has replaced the original technology. These ideas are good, but the implementation of this technology is too slow.

Ⅸ How is the blockchain industry? Is there any development advantage?

< p>What is the development trend of blockchain technology?
Trend 1: Blockchain technology is constantly iteratively updated and is developing in the direction of great integration
Trend 2: Blockchain structure is diversified and connected with real-world values bargeWith the development of blockchain to the present, the data structure and system architecture have evolved.
Trend 3: The development process of the blockchain industry is accelerating, and it has entered the main theme of moving from virtuality to reality
Blockchain 1.0 is digital currency, 2.0 is smart contract, and 3.0 is large-scale commercial application. The fog chain is one of the development trends in the blockchain 3.0 era.
The blockchain 1.0 era is an A to B transfer system represented by Bitcoin;
The blockchain 2.0 era is a simple smart contract system represented by Ethereum&rd;
The blockchain 3.0 era is an era of real application scenarios with high circulation and strong application represented by the fog chain! The innovative mechanism of Wulian Chain will lead the blockchain 3.0 era!
Trend 4: Blockchain application scenarios are becoming increasingly complex, and cross-chain interconnection is becoming more important
Trend 5: Blockchain standardization is accelerating, and countries are vying for the right to formulate standards
Now all countries are working hard to formulate Blockchain-related standards include Japan, the United States, the European Union and various well-known blockchain standards organizations.
Trend 6: Blockchain privacy protection mechanisms are diverse, becoming a key lubricant for activating commercial applications
Today’s privacy protection includes many types, such as ring signatures, multi-signatures, mixers, zero-knowledge proofs, simultaneous Stateful encryption and so on. The problem that many blockchain companies encounter now when they are launched is that banks and other institutions will say not to use new algorithms for me. If you want to implement it, it depends more on whether you can find a privacy protection algorithm suitable for business scenarios and integrate it with the real economy.
Trend 7: Blockchain security issues attract attention and require urgent attention and solutions. In October 2016, The DAO, a venture capital organization based on the Ethereum public blockchain platform, lost more than $50 million due to system vulnerabilities. Ethereum was stolen, and later there were Parity wallet freezing attacks, solar eclipse attacks on nodes, and even a line of code that ruined your life. Various security incidents involving wallets, exchanges, chains, smart contracts, etc. Various attacks.
Trend 8: Blockchain intellectual property competition is becoming increasingly fierce, and the Internet of Everything will expand the patent layout. At present, blockchain patent applications are mainly enterprises, and there is no market leader. China and the United States have an absolute advantage.
Trend 9: Blockchain helps regulatory technology, focusing on the new direction of chain governance
Regulatory technology mainly applies technologies such as big data, artificial intelligence, and blockchain, and regulatory authorities have applied these technologies to risk management control, anti-fraud, anti-money laundering and combating insider trading.
Trend 10: Blockchain talents have become a key link, and all parties have stepped up efforts to cultivate themStrength We all know that blockchain talent is becoming more and more expensive.

X Advantages of Blockchain Technology Classification of Blockchain Technology

The development of Blockchain technology is becoming more and more prosperous with the continuous expansion of applications. This kind of technology comes from various The strong development momentum of industry demand has brought about rapid changes in blockchain technology, which has attracted more and more attention to the achievements of various industries. From professional technology to resources, they are constantly concentrated in this industry, thus making blockchain technology more and more popular. The development of blockchain technology has entered a new stage, and the impact brought by the development of this blockchain technology has also attracted much attention.

When talking about blockchain technology, Bitcoin has to be mentioned. Many people know that the electronic currency Bitcoin does not rely on the issuance of a specific monetary institution, but is generated through a large number of calculations by a specific algorithm. In fact, the core that truly supports Bitcoin is blockchain technology.

How does the invisible and intangible Bitcoin operate through blockchain technology? The interpretation circulated in the industry is that blockchain can be regarded as a technical solution for collectively maintaining reliable databases through "decentralization" and "trustlessness". In layman’s terms, this technology can be understood as a technology in which everyone participates in accounting. In the past, people used centralized servers to keep accounts, but in the blockchain technology system, everyone can participate in accounting and jointly identify Authenticity of records.

“Through this technology, even if there is no neutral third-party organization, two parties that do not trust each other can achieve cooperation. In short, the blockchain is like a ‘machine that creates trust’. "Bubi Company is a leading blockchain service provider in China. It has made many breakthroughs in the blockchain technology platform, can meet scenarios with tens of millions of users, and has the ability to quickly build upper-layer application businesses.

The blockchain technology used by all parties involved in recording and storing information adopts a decentralized distributed structure, which saves a lot of intermediary costs and can better ensure data security; at the same time, it cannot be tampered with Timestamps can effectively solve problems such as data tracking and information anti-counterfeiting.

Will it become the next trend of Internet finance?

Although blockchain emerged with Bitcoin, the derived value of this technology has transcended digital currency. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to allow digital assets to flow freely. What Bubi wants to do is to create a new technology and product - to realize real value circulation and bring the Internet to a new level. With the application of this technology, there will be no central organization when transferring assets, and direct transfer of assets between us can be achieved.

In the current international financial market, the U.S. Central Bank, Swiss Bank, and some insurance and futures companies are all competing to develop blockchain technology. Fang Liang introduced that in the Internet financial industry, blockchain technology will first affect financial infrastructure such as payment systems, securities settlement systems, and transaction databases; later, the technology will also expand to general financial services, such as credit systems, "anti-money laundering", etc.

“The payment and clearing system in the financial field will evolve towards decentralization. The electronic ledger supported by blockchain technology is a reliable system that is error-free and cannot be tampered with. Quan and others have a profound impact." Li Yan said.

Therefore, industry insiders believe that blockchain technology may be the next trend in the Internet financial industry. As the interconnection of all things deepens, Yang Tao, assistant director of the Institute of Finance, Chinese Academy of Social Sciences, also said that blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources, and will also promote the improvement of existing financial system rules. Build a shared and win-win financial development ecosystem.

Blockchain technology will affect many industries

“Blockchain technology has been widely used in the era of big data.” Li Yan said frankly that in addition to the Internet financial field, Blockchain technology has been applied in many fields and has shown great prospects.

For example, the healthcare industry has benefited greatly from blockchain technology. In reality, patient private information leaks often occur, and centralized database or file cabinet management in medical departments is no longer the optimal choice. Medical institutions are using blockchain technology to keep patients' private information confidential.

In addition, blockchain technology also has important legal implications. In some civil fields, it is often necessary to provide evidence to determine blame, and blockchain technology can record every step and help judicial authorities identify the specific responsible person.

“Especially in the field of assets, whether it is physical assets such as real estate and cars, or intangible assets such as health and reputation, this technology can be used to complete registration, transactions, and tracking. It can be said that any lack of Blockchain technology will be useful in all areas of trustful production and life."

The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted The new development of various industries, the impact of this driving force on society, and the promotion of economic activities are also huge. Many new industry phenomena will occur one after another, and the public is also waiting to see, expecting this brand-new technology to be used by various industries. Better benefit all industries.
