Blockchain technology is a new A distributed 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.

『二』What are the current problems and challenges faced by smart contracts based on blockchain?

Jinwowo Group analyzes the following problems faced by smart contracts based on blockchain: Points:
1-Security issues: One of the key issues is security and trust. Smart contract systems are designed to be a trustless environment, which means that errors that occur cannot be corrected;
2-Privacy issue: A major challenge in effectively using the blockchain is that the blockchain provides complete transparency;
3-Unexpected scenario problem: Smart contracts sound very good, but how to correctly and appropriately handle contract execution in unexpected scenarios is a problem.

2. Solution: data model architecture design; business smart contract design; permission management and identity authentication design; access control mechanism design.

『四』How is the security of blockchain and what are the risks of blockchain

The hottest topic at the beginning of the new year is blockchain, but there are also Many people are skeptical about its security and risks. So what is the security of blockchain? What are the risks of blockchain? Below we will give you the answers one by one. I hope you will be able toHelps.
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.

『五』What are the challenges currently faced by the blockchain?

What challenges are currently faced by the blockchain
At this stage, the main application projects in the blockchain field are Divided into two aspects: one is new business models that are more compatible with blockchain technology, such as cross-border payments, supply chain finance, product traceability and other scenarios; the other is applications based on reform of existing centralized businesses, that is, using Token’s economic incentive mechanism.
With the development of technology, the number of application projects in this field is expanding rapidly. Many people believe that 2018 will be the year when blockchain will truly integrate with the real economy and explode. However, blockchain technology is still in its early development stage and faces challenges including the regulatory environment, lack of talent, and technical awareness.

From a technical perspective, applying blockchain technology to actual industry scenarios requires solving issues such as transaction speed, data consensus, and node maintenance. The current Bitcoin network onlyIt can handle seven transactions, while the more advanced Hyperledger technology can only reach the level of 200 to 300 transactions; this is still a long way from the centralized system that can process tens of thousands of transactions per second. In addition, the current lack of relevant incentive mechanisms in the field makes it difficult for participating nodes to operate in an orderly manner. From a regulatory perspective, although most countries are actively embracing blockchain technology, there are currently no relatively complete regulatory regulations and industry standards. Inappropriate regulatory measures may hinder the innovative development of such emerging technologies.
Affected by various factors such as the underlying technology that needs to be further matured, the lack of smart contract public chain platforms, the lack of ecological compatibility of various Tokens, and unclear government supervision; at this stage, the implementation of blockchain application projects is relatively slow. It shows that the quality of projects varies greatly. For this reason, analysts said that compared with general-purpose blockchains, what will achieve breakthroughs in the short term may be focused blockchains for specific scenarios and applications.

『Lu』 What are the current obvious shortcomings of smart contracts in blockchain technology?

“The working theory of smart contracts has not been realized for a long time. An important reason is because of the lack of ability to Digital systems and technologies that support programmable contracts. The emergence of blockchain technology solves this problem. It not only supports programmable contracts, but also has the advantages of decentralization, non-tampering, transparent and traceable processes, etc., making it naturally suitable for smart contracts. Therefore, it can also be said that smart contracts are one of the characteristics of blockchain technology."
Smart contracts based on blockchain technology can not only take advantage of smart contracts in terms of cost efficiency, but also avoid malicious behaviors that may harm the contract. Interference with execution. Smart contracts are written into the blockchain in digital form, and the characteristics of the blockchain technology ensure that the entire process of storage, reading, and execution is transparent, traceable, and cannot be tampered with. At the same time, a state machine system is built using the blockchain’s own consensus algorithm to enable smart contracts to run efficiently.
