① Is blockchain safe?

Hi, everyone, I am your Q&A assistant - Zi Xiaochen. Recently, blockchain resistance has been widely concerned and discussed. But there are many people who don’t know much about its safety. So today we will talk about the security issues of blockchain.
First of all, would you like to hear an easy-to-understand metaphor? A friend of mine joked: "Blockchain is like a password lock. Without a password, no one can open it." Although this is simple and interesting, it makes a lot of sense. Since the blockchain uses distributed ledger technology, data is stored in a huge network, and the transmission between each node uses asymmetric encryption, the blockchain has extremely high security, and third-party attacks are very vulnerable. difficult.
Secondly, of course there are some security issues that need attention. For example, hacker attack methods such as "51% attack" can pose a threat to the blockchain. In addition, there are also security risks in virtual currency trading venues, such as Bitcoin exchanges, and you need to pay attention to precautions. Therefore, when choosing a blockchain platform or participating in virtual currency transactions, you need to know more and consider carefully to avoid losses.
In short, blockchain is an open technology, which has huge advantages in ensuring data security and preventing tampering. But we also need to be alert to potential security risks and choose reliable platforms and exchanges to participate in cryptocurrency investments.
I hope my answer can help you better understand the blockchain and its security issues. If you have any questions or want to share your experience, please feel free to message me privately! Finally, don’t forget to like, comment and forward, follow my articles, more content is waiting for you!

② Does blockchain have compliance risks?

Yes, the application of blockchain technology may involve compliance risks.
First of all, in some countries and regions, governments or regulatory authorities may take different stances on digital currencies and other assets based on blockchain technology, and there will be a certain degree of legal, compliance and policy risks. . For example, some countries restrict or prohibit the use of digital currencies and other Bitcoin or blockchain derivatives. Therefore, when choosing the scope of application of blockchain technology, the local legal and regulatory environment needs to be considered.
Secondly, there are trust issues between participants in private chains or alliance chains, and there are also compliance risks in the construction of trust mechanisms. For example, in the financial field, banks or other financial institutions need to consider which trust model to use when using blockchain technology to comply with social ethics and potential legal requirements. For money-related transactions, legal requirements such as anti-money laundering and counter-terrorism must also be met.
In addition, due to the immutable and public nature of blockchain technology, it may inadvertently leak personal privacy, business secrets and other confidential information, causing privacy data leaks and security risks.
Therefore, enterprises and technology companies should carefully assess potential compliance risks and develop appropriate compliance security measures, such as complying with legal and regulatory requirements and establishing robust privacy protection measures.Protection mechanism, multi-dimensional strengthening of privacy data protection, etc., to ensure the compliance and data security of blockchain technology applications.

③ How is the security of blockchain? What are the risks of blockchain?

The hottest topic at the beginning of the new year is blockchain, but there are many more. People are skeptical about its security and risks, so how about the security of blockchain? What are the risks of blockchain? Below we will give you the answers one by one. I hope it will be helpful to you after reading them.
How is the security of blockchain Anyuan?
First of all, blockchain is a distributed database technology. Distributed technology mainly refers to storage architecture. The distributed architecture adopted by the blockchain not only stores the ledger data on each node, but also each node must contain the data of the entire ledger. This completely distributed architecture brings extremely high security, and no one can destroy all nodes at the same time.
Secondly, blockchain technology can achieve tamper resistance through "blocks" and "chains". The unit of data storage in the blockchain is the block. When each block is generated, it must contain the unique "characteristic value" of the previous block (which can be regarded as the ID card of the block). Each block is generated strictly according to the The order of time is lined up to form a "chain".
Security is a major feature of blockchain technology. However, from the perspective of privacy protection, the block chain emphasizes openness and transparency, and any node has the right to operate according to the consensus algorithm, so it is not suitable for scenarios where data privacy needs to be protected.
What are the risks of blockchain?
1. Technical risk: For example, the launch of Ethereum was once popular, but because it is a digital currency with smart contracts, it brings the risk of hacker attacks due to possible loopholes in smart contracts. THEDAO, the largest crowdfunding project in Ethereum, was hacked and lost more than $60 million.
2. Legal risks: The legality issues of digital currency issuance, notarization and confirmation of rights, and legality issues of evidence, including legality issues of smart contracts, digital bills, accounting and liquidation, and equity crowdfunding, are currently in my country and The rest of the world is still legally blank.
3. Crime risks: Using digital currencies to abscond with the money, using digital currencies to launder money and illegal gambling, using smart contracts and digital bills designed to defraud profits, using blockchain technology to commit anonymous crimes, etc. Due to the current regulatory gap, there may be huge criminal risks.
The above is what the editor brings to you. How about the security of blockchain? What are the risks of blockchain? of the entire content.

④ Risk control under the blockchain paradigm: reducing strategic risks and foreseeable risks

Marco Iansiti Karim Lakhani, "Harvard Business Review" Chinese version, January 2017, article "The Truth about Blockchain"

Research experience in the field of technological innovation tells us that only by eliminating obstacles in technology, government control, organization and society, can the blockchain revolution truly occur. If you don’t know how blockchain will occupy the high ground, it would be a mistake to rush into blockchain innovation.

Systemic risk. Speaking of systemic risks, we have to mention dramatic global economic downturns such as the credit crunch that followed the financial crisis of 2008-2009. For most companies, that is an external event that cannot be predicted or controlled. Global regulators are reshaping the financial world to avoid similar crises, and an important step in their strategy is to enhance the role of central counterparties (CCPs). A CCP is an entity that is inserted between the two parties in a financial transaction. After both parties agree to a transaction, CCP becomes a seller to any buyer and a buyer to any seller. In this process, CCP reduces counterparty credit and liquidity risk exposure through networking, reducing the risk of direct contact between the two parties when one party defaults, but the risk of doing so is still concentrated. The main roles of CCP are: 1. Manage settlement operation tasks and reduce settlement risks; 2. Monitor individual credit risks through membership approval and implementation of margins (initial and changed) to provide transparent risk management; 3. Deal with defaulting parties ;4. Supervise systemic risks in the market.

In financial markets managed based on blockchain, many CCP principles may be eliminated. It is conceivable that functions 1 and 2 of CCP will be replaced by smart contracts. DAOs are designed to create a relationship between two parties. Once certain terms embedded in the smart contract are touched, the receivables can be automatically transferred from one party to the other. Functions 3 and 4 of CCP can also be improved by blockchain technology, but it is unlikely to be fully automated because it requires a high degree of directionality and large-scale scene analysis capabilities. Relevant blockchain startups such as Digital Asset Holding and D-Pactum are working with CCP to redesign their technology in the direction of distributed ledgers and smart contracts without changing the role given to CCP by recent laws and regulations. This could develop into fundamental measures to increase the resilience of the financial system. On the distributed ledger, transparent and standardized transaction processes can be designed, and the relationship between capital and margin can occur automatically, thus reducing the risk burden of intermediary managers. By encoding smart contracts signed by each participant, the rules for managing crisis events can be as certain as possible.

Cyber ​​risks. This is the last external risk we will analyze, but not the least. Indeed, a lack of understanding or attention to the risks associated with cyber risks or critical infrastructure failures such as control systems, energy, transportation, telecommunications and financial infrastructure has the potential to have far-reaching consequences for national economies, multiple economic sectors and global businesses . conductThe responsibility for risk assessment and setting up risk management systems now falls on each business, but their internal practices and processes vary widely, and small businesses with immature risk management systems are more vulnerable to cyberattacks in this context.

Is blockchain a viable solution? no doubt. The development of digital currencies extends the secure use of cryptography and creates a business model with new types of resilience against cyberattacks. A complete system on a distributed ledger could provide a higher level of cybersecurity than a company's standard firewall technology. Because the distributed ledger is automated, and because of the principles of information sharing and the robustness of the consensus protocol, the ledger history is omnipresent and unchangeable. Therefore, in this system, high-tech cyber attacks can be prevented before they occur.

However, at the end of the analysis of external risks, it is worth noting that the emergence of digital currency has created for the first time a circulating currency that is not related to national, multinational government decisions or any real economy. In reality, the value of digital currency fluctuates greatly, but its direction and time are different from the market, thus maintaining non-correlation with a certain country's currency or stock market. As a result, Bitcoin has been called “digital gold,” and like gold, digital currencies have been used as safe-haven assets to limit the impact of macroeconomic risks.

In conclusion, before we delve into the amazing utility of blockchain in risk management, it is important to understand that blockchain is not a panacea. It should be viewed as one of many technologies building the next generation of risk management infrastructure.

⑤ What are the risks of blockchain transactions?

When conducting blockchain transactions, the three most catastrophic risks that need attention are (in order of severity from high to low): The biggest risks of personal risk, platform risk and policy risk: Personal risk If personal risks are not well controlled, you may encounter: 1. Passwords and private keys are stolen, and all digital assets in wallets and trading platforms are lost (unable to be retrieved) 2. Your information will be sold back and forth by the underground black industry, with almost no privacy. 3. If you use the same or similar password in other places (banks, securities trading platforms), assets in other places will also be stolen. How to avoid personal Risks: Increase password strength, do not reuse passwords, do not send passwords online... do not run naked on your computer (do not install security and anti-virus software), do not go to messy websites ("pornography, gambling and drug" websites are the hardest hit areas for Trojan viruses). All needed

⑥ What does blockchain risk control mean?

Blockchain risk control means

my country’s supply chain finance has been practiced for more than 10 years time. As banks are the main players on the funding side, their risk control logic mainly relies on the credit endorsement of core enterprises. Under the risk aversion strategy, pledge guarantee is the main credit strategy, such as inventory pledge, accounts receivable financing, advance payment financing, etc. However, the proportion of factoring business that purchases creditor's rights is low, and the self-repaying feature of trade financing has not been fully utilized. This is closely related to the bank’s credit innovation technology and risk control methods.Banks still have many technical difficulties in judging the authenticity of transactions and reviewing bills.
The blockchain architecture provides credit technology that "penetrates" multi-layer transaction structures, allowing banks to grant credit to nodes far away from the core enterprise. In existing supply chain finance, the credit leverage of core enterprises can generally only be transferred to first-tier suppliers or first-tier distributors. However, for suppliers and dealers above second-tier, banks lack direct transaction relationships with core enterprises. Because the core enterprise cannot provide credit endorsement, it cannot provide financing services. Under the blockchain architecture, transaction relationships with multi-node participation can be built, continuous contractual relationships can be built based on ERP, and combined with inventory management models such as cloud warehouses and VMI, the entire chain can obtain credit support from core enterprises.
Blockchain architecture can break through the credit bottleneck that banks urgently need to solve. The best support of the virtual system for supply chain finance is the visualization of transactions at all nodes in the entire chain, including not only the online transaction chain (business flow), but also various supporting processes of the transaction, such as offline logistics and documents. Flow, real evidence of value exchange, etc. Only when the bank believes that it has obtained sufficient and adequate information can the collateral risk be eliminated and sufficient credit services can be achieved.
1. From virtual to parallel and interactive
The rapid development of e-commerce, technology finance, virtual reality and many other intelligent technologies have fundamentally changed the procurement, production, marketing and consumption of modern business. and other models, forming a parallel world in which the real physical world and virtual cyberspace are closely coupled, virtual and real interact, and co-evolve.
Reliable data is the basis for the existence of the virtual world. The virtual system built based on the blockchain architecture, in the "duplex interaction" mode, can reflect the transaction history in a way that is isomorphic with the real system. In fact, the virtual system already has objective reality, because the virtual system is no longer what it used to be. An information system that is arbitrarily deleted is a parallel system corresponding to the real system. The real system and the virtual system have the same authenticity, so the credit of the virtual system is also true and credible. This is very important for the financial system based on "authenticity". The development of business has a great supporting role.
The virtual system under the blockchain architecture is parallel to the real system. In other words, under the blockchain architecture, the system that humans can understand is divided into two worlds (composed of two worlds). Both worlds are real, complement each other, and execute interactively.
2 The importance of government nodes
Relevant government departments have rich and high-quality credit information resources, such as industry and commerce, taxation, public security, customs, inspection and quarantine and other departments. The information acquisition by these departments has strict requirements and is protected by national regulations. It is based on their own business scope, but there is a lack of unified standards.
Information from government departments is generally communicated internally and does not interact with, exchange, or share resources with social business systems. In the existing supply chain finance platform, credit information resources are scattered, transparency is low, information is difficult to obtain, and costs are high, which greatly restricts credit information.Use innovation and the credit rating business itself. A large number of valuable information resources in government departments are idle and wasted, which is even a "bottleneck" problem in commercial credit innovation.
Foreign trade, for example, includes transportation services, port and airport logistics parks (bonded), customs and electronic platforms, inspection and quarantine, comprehensive service platforms (such as One Access) and a large number of functional service agencies. Driven by management and efficiency, various institutions and platforms have continued to innovate service models in recent years and have made great progress in efficiency. However, in practice, the issue of trade facilitation has not been well resolved. At present, the main problem is that the service functions of customs, ports, and logistics parks are not built around "trade" itself, which creates great difficulties for the platform's financial service innovation.
Referring to advanced foreign models, the construction of the business platform is centered on "trade" and is a large service platform that integrates various government service departments, functional departments, and operating entities. Taking trade as the center means taking the trading network centered on "business flow" as the highest-level platform, and other platforms, entities, and functional agencies will develop and connect services and processes around the trading platform. The ultimate goal is to achieve "trade facilitation" change". This model will provide huge space for the introduction and innovation of supply chain financial services, and the result of facilitation will be a rapid decline in transaction costs. This is also one of the important strategies for developing the real economy in our country.
In the future, supply chain finance in large-scale platforms will inevitably introduce government nodes as one of the keys to the blockchain architecture. After the government node joins, high-quality credit information can enhance the overall credit of the system. It will also promote the trustworthiness of all parties involved in the transaction and increase motivation, providing favorable conditions for the innovation of financial services and the expansion of financing scope.
The blockchain architecture is not decentralized, but reduces the cost of traditional credit intermediaries. The addition of government nodes will not lead to the emergence of a centralized model. Government nodes are on an equal footing with other nodes. Government nodes are not Does not exercise control but performs administrative functions in an open environment. The information is compiled from the Internet. For more information, please pay attention to e-ticket!

⑦ What applications can blockchain technology have in the insurance industry?

Blockchain technology also has incomparable advantages in the insurance industry. From the perspective of data management, the application of blockchain technology by insurance companies can effectively improve risk management and control capabilities, including the risk supervision of insurance companies and the risk management of policyholders.

The application of blockchain technology in the insurance industry can strengthen the internal risk supervision of insurance companies. Blockchain technology can record the daily operating processes of insurance companies on nodes, and can achieve in-process control over the company's capital flow, investment status, compensation amounts and other businesses, and improve the company's risk management and control capabilities.

In addition, blockchain technology is safe, reliable, and cannot be tampered with at will, ensuring that the information obtained by the policy holder is true and effective, thereby enhancing the policy holder's risk management capabilities.

⑧ Can you make money by investing in blockchain now? Is it risky? How big is the risk

First, there is the risk of absconding with money, and the assets raised lack auditing and custody. Now a standard ICO is like this. A white paper is issued for everyone to read, and then it is over as soon as it is launched. There are still many potential rules. For example, in the past few years, there were many situations where an ICO project came out, everyone invested a lot, and then disappeared after it was completed. So far, this is still the case. Therefore, there is still the risk of the project proponent absconding with the money.
Second, the risk of over-commitment. The traditional IPO is that the company has to do well, and everyone can see it clearly when I go to sell it. With ICO, I write a few pages of paper to talk about what I plan to do and what functions I want to achieve, and then everyone gives me the money. Whether it can be implemented well is actually a question mark.
Third, there is the risk of overvaluation. At present, a very detailed or convincing pricing mechanism has not yet been formed. It is more up to the project initiator to generate a pricing based on the needs of the project development or their own understanding. There may be the so-called periodic inflated investment problem.
Fourth, investors are too optimistic. Investors may see more space for future ICO projects, but in fact, in the long run, there is no sustained huge profit.
Fifth, project management and stock risk make it difficult for investors to control the project. After the project is completed, there is often a certain development cycle to follow. How will the project be developed and how will it be promoted? Very few ICO projects can lay out very clear future development plans. This means that what investors can do after investing their money is actually beyond their control.

⑨ Please tell me, do many blockchains now have risks?

Yes, blockchains are now high-risk projects.

⑩ The statement that blockchain can enhance financial risk control is incorrect

The statement that blockchain can enhance financial risk control is correct.
Risk control is an essential part of the financial field. In recent years, in order to achieve more accurate and efficient risk control, financial institutions have introduced big data technology. The real demand and flow of funds lack an effective regulatory mechanism, which to a certain extent contributes to the irrational rise in the real estate market. Blockchain technology can effectively avoid and prevent risks under the development goal of mutual benefit and win-win on the Internet. Achieve sustainable and balanced development of Internet finance.
Extended information: 1. What are the main application fields of blockchain 1 technology
Blockchain is the core supporting technology of the digital cryptocurrency system represented by Bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transactions based on decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Coordination and collaboration thus provide solutions to the common problems of high cost, low efficiency and insecure data storage in centralized institutions.
The application fields of blockchain include digital currency, certificates,Finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered, which has had a relatively large impact on the domain name industry.
2. What are the three core technologies of blockchain
1. Blockchain links
As the name suggests, blockchain is a chain composed of blocks. Each block is divided into two parts: block header and block body (including transaction data). The block header includes the hash (PrevHash) value (also called hash value) of the previous block used to implement block linking and the random number (nonce) used to calculate the mining difficulty. The hash value of the previous block is actually the hash value of the header of the previous block, and the rules for calculating random numbers determine which miner can obtain the power to record the block.
2. Consensus Mechanism
Blockchain was born with Bitcoin and is the basic technical architecture of Bitcoin. Blockchain can be understood as a decentralized accounting system based on the Internet. A decentralized digital currency system like Bitcoin requires blockchain to ensure the consistency of accounting by each honest node without a central node. Therefore, the core of blockchain technology is a consensus mechanism that reaches a consensus on the legality of transactions among individuals who have no basis for trust in each other without central control.
There are currently four main categories of blockchain consensus mechanisms: PoW, PoS, DPoS, and distributed consensus algorithms.
