7. Interpretation of the "Blockchain Information Service Management Regulations" | "Tourism" laws can be followed

On January 10, 2019, the State Internet Information Office issued the "Blockchain Information Service Management Regulations" Regulations" (hereinafter referred to as the "Regulations"), and will come into effect on February 15, 2019. In order to help readers understand the content of the "Regulations" more clearly and straightforwardly, we have conducted a professional interpretation of this new regulation and compiled several highlights of the "Regulations": 1. It is clarified that the competent department of blockchain information services shall be responsible for Article 3: The supervision, management and law enforcement departments of blockchain information services are Internet Information Offices at all levels. 2. Clarify the definition of blockchain information service providers. According to Article 2 of the "Regulations", the so-called blockchain information services refer to the services provided to the public through Internet websites, applications, etc. based on blockchain technology or systems. Provide information services. Blockchain information service providers refer to entities or nodes that provide blockchain information services to the public, as well as institutions or organizations that provide technical support to entities that provide blockchain information services. According to the above definition, it can be seen that only information services such as news reports about blockchain and Bitcoin are provided to the public, such as mobile APPs such as Mars Finance and Bikuaibao, as long as the underlying technology for providing services is not based on blockchain technology or systems. It does not belong to the blockchain information services mentioned in the "Regulations" and is not subject to the "Regulations". And mobile apps or games such as "NetEase Planet", "Ni Shui Han", "A Chinese Ghost Story" and other mobile apps or games, in view of the fact that some of them make use of regionalBlockchain technology or systems are used to provide services to users, so their operators should be blockchain information service providers. In addition, in view of the above definition, even if an organization or institution itself does not provide blockchain information services to the public, as long as it provides technical support to blockchain information service subjects, it still belongs to blockchain information services. Providers are bound by the Regulations. This means that the more popular model of "overseas establishment of entities to issue coins on the chain + domestic companies to provide technical services" may come to an end. 3. Clarify the security management responsibilities of blockchain information service providers. The "Regulations" clearly stipulate the responsibilities of blockchain information service providers. Mainly include: 4. Clarify the filing responsibilities and related procedures of blockchain information service providers. In addition to the above responsibilities, blockchain information service providers should also perform filing responsibilities: 1. Within ten working days from the date of provision of services. Fill in the name, service category, service form, application field, server address and other information of the service provider through the Blockchain Information Service Registration Management System of the Cyberspace Administration of China and perform the registration procedures. 2. If the service items, platform address and other matters are changed, the change procedures shall be completed within five working days from the date of change. 3. If the service is terminated, the cancellation procedures should be completed thirty working days before the service is terminated, and proper arrangements should be made. 4. Those who engage in blockchain information services before the "Regulations" are promulgated (i.e. before January 10, 2019) shall comply with the regulations within twenty working days from the date when the "Regulations" come into effect (i.e. February 15, 2019). Complete relevant procedures. 5. Blockchain information service providers should log in to the blockchain information service filing management system within the specified time and provide relevant information to cooperate with the Internet Information Office in conducting regular inspections of filing information. Registration agencies: Internet information offices at all levels. Filing procedures: After the blockchain information service provider submits materials, the Internet Information Source Information Office shall file the materials within twenty working days, issue a filing number, and report to the State Internet Information Office through the Blockchain Information Service Filing Management System. The public publishes the filing information; if the materials are incomplete, the filing will not be granted, but the filing person shall be notified within twenty working days and the reasons shall be explained. The promulgation of the "Regulations" clarified the subject boundaries of blockchain information service providers, stipulated in detail the subject responsibilities of blockchain information service providers, and filled the current domestic regulatory gap in the field of blockchain information services. , marking the arrival of the "regulatory era" in the field of blockchain information services. For the blockchain information service industry, it means more orderly and healthy development; for practitioners who are currently engaged in or are interested in providing blockchain information services in the future, it means higher compliance requirements. .

8. How to detect the risk level of blockchain smart contracts

With the acceleration of digital transformation in Shanghai, blockchain technology has been deeply used in many fields such as government affairs, finance, logistics, and justice. application. In the process of application, not only new business forms and business models have been born, but also many security issues have arisen.Safety supervision is particularly important. As one of the important means of supervision, security evaluation has become a focus of many blockchain R&D manufacturers and application companies. This article talks about some of our exploration and practice on the blockchain compliance security assessment that everyone is concerned about.
1. Blockchain technology evaluation
Blockchain technology evaluation is generally divided into functional testing, performance testing and security evaluation.
1. Functional testing
Functional testing is a test of the basic functions supported by the underlying blockchain system, with the purpose of measuring the capabilities of the underlying blockchain system.
Blockchain functional testing is mainly based on GB/T 25000.10-2016 "System and Software Quality Requirements and Evaluation (SQuaRE) Part 10: System and Software Quality Model", GB/T 25000.51-2016 "System and Software Quality" Requirements and Evaluation (SQuaRE) Part 51: Quality Requirements and Testing Details for Ready to Use Software Products (RUSP)" and other standards to verify whether the software under test meets the requirements of relevant test standards.
Blockchain function testing specifically includes networking methods and communication, data storage and transmission, encryption module availability, consensus function and fault tolerance, smart contract function, system management stability, chain stability, privacy protection, and interoperability , account and transaction types, private key management solutions, audit management and other modules.
2. Performance testing
Performance testing is a type of test implemented and executed to describe the performance-related characteristics of the test object and evaluate it. Most of them are used in project acceptance evaluation to verify the established Whether the technical indicators are completed.
Blockchain performance testing specifically includes high-concurrency stress test scenarios, peak impact test scenarios, long-term stable operation test scenarios, query test scenarios and other modules.
3. Security Assessment
Blockchain security assessment mainly conducts security testing and evaluation of account data, cryptography mechanisms, consensus mechanisms, smart contracts, etc.
The main basis for blockchain security evaluation is "DB31/T 1331-2021 General Requirements for Blockchain Technology Security". You can also refer to standards such as "JR/T 0193-2020 Blockchain Technology Financial Application Assessment Rules" and "JR/T 0184-2020 Financial Distributed Ledger Technology Security Specifications" based on actual testing needs.
Blockchain security assessment specifically includes storage, network, computing, consensus mechanism, cryptography mechanism, timing mechanism, personal information protection, networking mechanism, smart contracts, services and access, etc.
2. Blockchain Compliance Security Assessment
Blockchain compliance security assessment generally includes “Blockchain Information Service Security Assessment”, “Network Security Level Protection Assessment” and “Special Funding Projects” "Acceptance Evaluation" three categories.
1. Blockchain Information Service Security Assessment
Blockchain Information Service Security Assessment is mainly based on the "Blockchain Information Service" issued by the State Internet Information Office on January 10, 2019.Information Service Management Regulations (hereinafter referred to as the "Regulations") and the national blockchain standard "Blockchain Information Service Security Specifications (Draft for Comments)".
The "Regulations" aim to clarify the information security management responsibilities of blockchain information service providers, standardize and promote the healthy development of blockchain technology and related services, avoid blockchain information service security risks, and provide blockchain Provide effective legal basis for the provision, use and management of information services. Article 9 of the "Regulations" states: Blockchain information service providers that develop and launch new products, new applications, and new functions must report to the national and provincial, autonomous region, and municipality Internet Information Offices for security assessment in accordance with relevant regulations.
The "Blockchain Information Service Security Specification" is a construction and preparation project led by the Institute of Information Engineering of the Chinese Academy of Sciences and jointly participated by Zhejiang University, China Electronics Technology Standardization Institute, Shanghai Information Security Evaluation and Certification Center and other units. National standards for evaluating the security capabilities of blockchain information services. The "Blockchain Information Service Security Specification" stipulates the security requirements that blockchain information service providers of alliance chains and private chains should meet, including security technical requirements and security assurance requirements as well as corresponding test and evaluation methods, and is suitable for guiding blockchain Chain information service security assessment and blockchain information service security construction. The security technical requirements and guarantee requirements framework proposed by the standard are as follows:
Figure 1 Blockchain information service security requirements model
2. Network security level protection evaluation
The main basis for network security level protection evaluation includes "GB/T 22239-2019 Basic Requirements for Network Security Level Protection" and "GB/T 28448-2019 Network Security Level Protection Evaluation Requirements".
As an emerging information technology, the application system built by blockchain is also an object of level protection and needs to be evaluated for level protection in accordance with regulations. The general requirements for level protection security evaluation are applicable to the evaluation of the infrastructure part of the blockchain, but currently there are no blockchain-specific security requirements. Therefore, the expansion requirements for blockchain security evaluation still need to be further explored and studied.
3. Special fund project acceptance evaluation
According to the relevant regulations of the Municipal Economic and Information Technology Commission, information technology special fund projects are required to issue a safety evaluation report during project acceptance. The acceptance evaluation of blockchain application projects will be carried out in accordance with Shanghai’s latest blockchain local standard "DB31/T 1331-2021 General Requirements for Blockchain Technology Security".
3. Exploration and practice of blockchain security assessment
1. Standard preparation
Shanghai Assessment Center actively participates in the preparation of blockchain standards. Led by the Shanghai Evaluation Center, Suzhou Tongji Blockchain Research Institute Co., Ltd., Shanghai Qiyin Information Technology Co., Ltd., Shanghai Moheng Network Technology Co., Ltd., the First Research Institute of Telecommunications Science and Technology and other units participated in the preparation of the blockchain local standard " DB31/T 1331-2021 General Requirements for Blockchain Technology Security" was officially released in December 2021. In March this yearIt will be officially implemented on the 1st. The blockchain national standard "Blockchain Information Service Security Specification", which the Shanghai Assessment Center participated in the preparation of, is in the stage of soliciting opinions.
At the same time, the assessment center also participated in the compilation of primary and intermediate textbooks for blockchain engineering technicians organized by the Ministry of Human Resources and Social Security and led by Tongji University, and was responsible for compiling the chapter "Testing the Blockchain System".
2. Project Practice
In recent years, the Shanghai Assessment Center has conducted a large number of blockchain security assessment practices based on relevant technical standards, including grade protection assessment, information service security assessment, project security assessment, etc. In the evaluation practice, the main security issues discovered are as follows:
Table 1 Blockchain is mainly a security issue
Serial number
Evaluation items
Problem description
1
Consensus Algorithm
The consensus algorithm uses Kafka or Raft consensus and does not support Byzantine fault tolerance or tolerate malicious node behavior.
2
On-chain data
On-chain sensitive information is not encrypted, and all data on the chain can be accessed through the query interface or blockchain browser.
3
Cryptographic Algorithm
The random numbers used in the cryptographic algorithm do not meet the randomness requirements of GB/T 32915-2016.
4
Node Protection
For the alliance chain, security protection measures failed to be configured for the area where the node server is located.
5
Communication transmission
When communicating between nodes, the blockchain and upper-layer applications, no secure information transmission channel has been established.
6
Consensus Algorithm
The number of nodes deployed in the system is small, and sometimes the number of fault-tolerant nodes required by the consensus algorithm is not even reached.
7
Smart Contract
The operation of the smart contract is not monitored, and problems that arise during the operation of the smart contract cannot be discovered and dealt with in a timely manner.
8
Services and Access
Upper-layer applications have access control flaws such as unauthorized and unauthorized access, leading to business confusion and data leakage.
9
Smart Contract
Smart contract coding is not standardized. When an error occurs in the smart contract, the smart contract freezing function is not provided.
10
Smart Contract
The running environment of smart contracts is not isolated from the outside, and there is a risk of external attacks.
3. Tool Application
When the evaluation center organized and compiled the "DB31/T 1331-2021 General Requirements for Blockchain Technology Security", it has considered the connection needs with the graded protection evaluation. The "infrastructure layer" security in DB31/T 1331 is consistent with the relevant requirements of the secure physical environment, secure communication network, security area boundary, secure computing environment, security management center, etc. of level protection, "protocol layer security", "extension layer" "Safety" is moreReflect the unique security protection requirements of blockchain.
Based on the relevant security requirements of DB31/T 1331, the assessment center is organizing and compiling extended blockchain assessment requirements. The relevant results will be applied to the network security level protection assessment tool - Assessment Expert. By then, evaluation institutions using the "Evaluation Expert" software will be able to carry out blockchain security evaluations accurately, standardly and efficiently, discover blockchain security risks, and put forward corresponding rectification suggestions

9. Various places have successively After banning Bitcoin and Ethereum "mining", NFT blockchain will be the next step

Although China bans cryptocurrency transactions and "mining", the exploration of blockchain technology continues . At the just-concluded World Artificial Intelligence Conference, Da Hongfei, founder and CEO of Distribution Technology, said in an interview with China Business News that “the manageability of blockchain” is a recent focus. The current scale and growth rate of the global public chain market is much higher than that of the alliance chain business. However, public chains have many limitations, such as illegal crimes, hacker theft, network risks, regulatory obstruction, etc., and cause huge irreparable losses. Therefore, how to increase the manageability of blockchain will be an important issue for blockchain to become mainstream.

The currency circle has been very unstable in the past two months. On May 21, the Financial Stability and Development Committee of the State Council issued a document stating "Crack down on Bitcoin mining and trading activities." On May 25, the Inner Mongolia Development and Reform Commission issued eight measures (draft for comments) to combat and punish virtual currency “mining”. On June 9, the Qinghai Provincial Department of Industry and Information Technology issued the “About Mining of Virtual Currencies” "Notice on Cleaning Up and Rectifying the Project", and cleaning up and rectifying the relevant virtual currency mining/mining activities.

On June 18, the Sichuan Provincial Development and Reform Commission issued the "Notice of the Energy Bureau on Cleaning up and Shutting Down Virtual Currency "Mining" Projects. For virtual currency mining/mining, the relevant power in Sichuan Enterprises need to complete the screening, cleaning and shutdown work before June 20.
