❶ Hot! Create and play with your own blockchain in 5 minutes

Blockchain is developing so fast this year! From an unfamiliar concept at the beginning, it has now taken off in various industries. A single spark has the potential to start a prairie fire. I really hope I can have my own blockchain to practice with! But how can one person and one computer set up a blockchain environment? The blockchain is so popular that it is not easy to say that I love you!


Don’t Worry! The editor has been addicted to blockchain and smart contracts and can’t extricate himself! Now I will take you step by step to start from scratch and create your own blockchain in 5 minutes! ~
The SuperVessel platform developed by IBM China Research Institute provides a blockchain development and testing environment for blockchain enthusiasts and developers. Through this platform, users can create multi-node blockchains based on Hyperledger Fabric for free and super quickly, and play with smart contracts on their own chains.

0.
Preparation
All you need is your local browser!
1. Register an account
Access the public beta address of SuperVessel blockchain service: 8800/bc.
Click the Log in button in the upper right corner, click Register in the pop-up window, fill in your email and password and submit. At this time, it is recommended to check the activation email in your mailbox and activate your account (Editor's tip: It doesn't matter if you activate lazily, but some advanced services must be activated before they can be used).
2.
Quickly create your own blockchain
After registration is completed, return to the homepage and click on the huge GIVE ME A BLOCKCHAIN ​​(Give me a blockchain!) button. Select the Consensus Plugin (consensus plug-in) and Size (number of blockchain network nodes) you want in the pop-up box.
Editor's note: Currently there are two consensus plug-ins officially provided by Hyperledger Fabric: noops and pbft.
After clicking Submit, you will get your own blockchain in a few seconds and automatically enter the monitoring panel. That’s right, getting your own blockchain is that simple!
After entering the monitoring panel, you can see that the left side is the smart contract management panel, including the management and deployment of smart contracts; the right side is the network panel, which displays the applied blockchain network status, topology, and connections between nodes. Latency information, etc. are clear at a glance; click the telescope icon in the upper right corner to monitor the log information of each node in real time. The bottom is the blockchain panel, which shows the overall situation of the current blockchain. In the initial state, there is only one block.
3. Deploy and use smart contracts
Next, the editor will teach you how to deploy smart contracts in your ownDeploy and use smart contracts on the blockchain.
Under the Smart Contracts tab of the smart contract management panel, 2 smart contracts are listed as examples, namely map and chaincode_example02. The map contract can store key-value pairs, and the chaincode_example02 contract can simulate transfers and queries between two people.
Editor's note: The codes for these two sample contracts can be found in the Hyperledger Fabric source code.
Take the deployment and use of the chaincode_example02 contract as an example:
Deploy the contract
Click the Deploy button corresponding to the chaincode_example02 contract, and fill in the initialization value of the contract, including the contract name, initial function, and initial parameters. The initial function of the contract is init, and the initial parameters need to be filled in according to the format, such as ["a", "100", "b", "200"], which means registering two people a and b, giving them 100 units and 200 units respectively.
Click the Deploy button and the contract will be deployed in your blockchain. The process will take about 20 to 40 seconds. When a new block appears on the blockchain panel, it usually means that the contract has been deployed.
Call the contract
After the deployment is completed, view the deployed contract instance under the My Deployment tab of the smart contract management panel.
Click the Invoke button below the Action to call the smart contract, and fill in the called method name and corresponding parameters (the method names and parameters of different contracts have different meanings, which are related to the content of the contract). For this contract, call the invoke method name and fill in the parameters ["a", "b", "50"], which means a transfers 50 units to b.
After clicking Submit to complete the call, you can view the blockchain situation and a new block will be generated.


Query Contract
After the call is completed, you can query the contract execution results. Still under the My Deployment tab, click the Query button under Action to query the smart contract, and fill in the query method name and corresponding parameters. If you select the query method name and fill in the parameter ["a"], it means querying the current unit of a.
After clicking Submit, you can see that the current unit of a is 50. You can try query b again!
OK, then you can continue to operate the contract, observe the blockchain situation, or deploy a new smart contract, such as map, on the blockchain. For ease of use, the method names and parameter formats for deploying, calling, and querying contracts are all filled in by default. You only need to select a method name and change the parameters as you like! See if you can play with the chainHow long~
4. Upload and test your own private smart contract
In addition to the two public smart contracts currently provided, you can also upload and test your own private contract! Private contracts can only be seen by you.
Click Import private smart contract under the Smart Contracts tab.
After filling in the contract name and description, and uploading the contract code file, click Import to complete the upload.
Then the contract I uploaded will appear in the Smart Contracts list and can be deployed, called and queried as before.

❷ How to detect the risk level of blockchain smart contracts

With the acceleration of digital transformation in Shanghai, blockchain technology has been widely used in government affairs, finance, logistics, It has been widely used in many fields such as justice. During the application process, not only new business forms and business models have been born, but also many security issues have arisen, so security 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 Management Regulations" issued by the Cyberspace Administration of China on January 10, 2019 (hereinafter referred to as "Regulations") and refer to the national blockchain standard "Blockchain Information Service Security Specification (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 infrastructure part of the blockchain, but currently no specific blockchain requirements are proposed.Some 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 and will be officially implemented on March 1 this year. 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 the smart contract cannot be discovered and dealt with in a timely manner.About problems that arise during operation.
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" "Security" more reflects the unique security protection requirements of the 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
