Ⅰ What are the advantages of blockchain traceability compared with other traditional traceability models?

Traditional traceability systems generally use a centralized ledger model, controlled by various market participants. Recording and saving in a scattered and isolated manner is an information island model. In the centralized ledger model, who maintains the ledger as the center becomes the key to the problem. Whether it is the source company or the channel provider, since they themselves are all stakeholders in the circulation chain, when the ledger information is not beneficial to themselves, At any time, you may choose to tamper with the ledger or falsely claim that the ledger information is lost due to technical reasons.
Under the information island model, each market participant maintains a ledger on his own. This ledger is commonly known as a ledger, and after being digitized, it was named the purchase, sale and inventory system. Whether it is a physical ledger or an electronic purchase, sale and inventory system, the owner can tamper with it or make it up at will. Blockchain's real-time reconciliation capabilities in registration and settlement scenarios, and its immutability and timestamp capabilities in data storage scenarios provide powerful tools for traceability, anti-counterfeiting, supply chain finance, and supply chain management scenarios.
Hongqiao Hi-Tech’s blockchain industry-specific application design uses the integrity and correlation of trusted transaction data to form a closed-loop self-certification capability for data on the chain. Used to verify the authenticity of digital documents and transaction records, and to track the origin of products and merchandise throughout the supply chain. This data proving product authenticity and origin is generally used by businesses and financial institutions in the assessment and processing of credit and loans.

II How does blockchain technology ensure the authenticity of electronic evidence

We mainly apply blockchain technology to the field of distributed electronic data storage, including contract storage, Email storage, file storage, structured data storage, etc.

The specific manifestations of electronic evidence in judicial practice are becoming increasingly diverse, and the frequency of use and data volume of electronic data storage have increased significantly. Different types of electronic evidence are formed in different ways, but they generally have the characteristics of being easy to perish, easily tampered with, and highly dependent on technology. Compared with traditional physical evidence, it is more difficult to determine the authenticity, legality, and relevance of electronic evidence in judicial review. .

Blockchain technology can be used to securely protect electronic data, prevent tampering, and leave traces of data operations throughout the entire life cycle of electronic data generation, collection, transmission, and storage, thereby providing Provide effective means for review by relevant agencies. Blockchain technology is used to preserve electronic evidence, and the electronic data that needs to be deposited are recorded in the form of transactions, stamped with timestamps, and recorded in blocks, thereby completing the process of data preservation and evidence depositing. During the data storage process, multiple participating nodes jointly witness and jointly maintain a distributed ledger, thus greatly reducing the possibility of data loss, tampering, and attack. The combination of blockchain and electronic data storage can reduce the cost of electronic data storage, facilitate electronic data collection and evidence identification, and improve litigation efficiency in the field of judicial storage.

Ⅲ ElectricityWhat is the blockchain certification technology of sub-contracts

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is based on cryptography. A distributed ledger that is tamper-proof and unforgeable.

Its non-tamperability and non-forgery are important features of the electronic contract system, which effectively improves the security of electronic contracts.

In 2016, we jointly launched the "Legal Chain" with Microsoft (China) and Onchain, which deeply integrated electronic contracts with blockchain technology. The signing time, signing subject, and file hash of electronic contracts were The digital fingerprint information of the value will be broadcast to the respective nodes of all members of the "Legal Chain". Once all information is stored, no party can tamper with it, making electronic evidence tamper-proof and ensuring its objective authenticity.

IV How should intellectual property rights be stored on the blockchain?

Blockchain certification, simply put, is to store electronic data on the blockchain for preservation. .

Microcopyright is a brand of Yibaoquan. Through microcopyright, the data for work rights verification, network evidence collection, and certificate preservation will be stored on the blockchain in the form of Hash, relying on the blockchain to decentralize With the characteristics of digitalization and distributed storage, it can store evidence on the blockchain and effectively ensure the originality and non-tamperability of electronic evidence.

Currently, it has been awarded the 2018 Industrial Internet Pilot Demonstration Project of the Ministry of Industry and Information Technology (the only blockchain selected project), and the first batch of domestic blockchain information service registration enterprises by the Cyberspace Administration of China in 2019 .

IV What are the advantages of blockchain compared to traditional technology

Hello, we are Shanghai Wanglian Information Technology Company. Compared with traditional technology, blockchain , with properties that cannot be tampered with. The blockchain traceability system VoneTracer launched by our company adopts a variety of data collection methods, one item per code, the traceability is true and reliable, and applies industry-leading technology. The bottom layer adopts the blockchain service BAAS platform independently developed by Wanglian. Such technical features can technically ensure that data is different from traditional traceability, and the credibility of the data will be greatly improved.

VI 2. What is the difference between blockchain trust and traditional model trust?

The difference between blockchain trust and traditional model trust is as follows.
1. The most different thing about trust in the blockchain is that it uses mathematics, computer technology and encryption to make the record of information unchangeable, and writes the cooperation agreement on the blockchain through smart contracts, and finally in the conditions The contract is automatically executed after satisfaction. Blockchain eliminates trusted third parties. Through blockchain, people do not need to 100% trust each other or trust third-party institutions. It does not eliminate trust issues, nor does it completely eliminate the need to consider trust issues during the cooperation process. , people still need to trust, but changes the object of trust from people and organizations to a blockchain network composed of consensus mechanisms.
2. The traditional trust system mainly comes from two aspects: country and culture. The state uses its own credibility and public power to endorse the trust of both parties; culture refers to some implicit rules, such as the trust system of various regional customs and the possible emergence of private third-party institutions. The cost of state execution is too high, and it is impossible to rely on the state for everything. The cultivation of cultural trust takes too long and cannot meet everyone's needs. Society is very complex. It is impossible to sign a contract for everything, and it is impossible for the state to intervene in everything.

Ⅶ What is the blockchain certificate of electronic contract?

Simply speaking, the blockchain is a distributed bank accounting system, a trust network without a central organization , is a distributed database. Due to its distributed storage, decentralization and other characteristics, it can effectively prevent tampering and denial, and has system stability that is unmatched by traditional models.

Based on the above characteristics, blockchain technology has been integrated with the financial industry and has been applied on a large scale, achieving remarkable results. In August 2016, we joined forces with Onchain to jointly launch the multi-party open blockchain alliance "Fa Chain" based on Microsoft's trusted cloud technology and open platform, based on Microsoft's comprehensive technology and open platform.

Based on the technical support of "FaChain", we have reached cooperation with Alibaba Mailbox and launched the world's first mailbox certificate storage product based on blockchain technology. As the Internet environment grows, the demand for electronic certificates will also grow, and our "legal chain" will also play a greater role.

ⅧWhat are the applications of blockchain electronic evidence in the evidence storage process?

Blockchain has the characteristics of decentralization, distributed storage, encryption algorithm, non-tampering, and traceability. It has natural technical advantages in electronic data storage, and can well solve the problems of easy loss and tampering of stored data in traditional storage methods.

Take Yibaoquan’s blockchain intellectual property protection platform micro-copyright as an example. Micro-copyright uses the SHA-512 hash algorithm, timestamp service, and PBFT consensus algorithm to The data is encrypted, and the electronic data is stored in the form of Hash on the blockchain, and then the electronic data is synchronously stored in the notary office, judicial appraisal center, Internet court, arbitration committee, copyright protection center, and CA through the preservation chain open platform. On nodes such as institutions, the originality and non-tamperability of electronic evidence can be effectively guaranteed through blockchain decentralization and distributed storage.

Ⅸ What is the prospect of blockchain certification

Since blockchain was included in the new infrastructure, the development of blockchain has been very hot. Looking at the current application of blockchain Look, certificate deposit is its main application scenario, which can well solve problems encountered in industries such as electronic contracts, intellectual property, finance, and logistics traceability.
The widespread application of blockchain certificates has made traditionalThe data storage and evidence collection methods have been impacted and challenged. As an emerging and cost-effective method of evidence storage, blockchain evidence storage has been increasingly adopted by governments and enterprises, and has been recognized by the highest judge as having legal validity.
Blockchain evidence actually covers the entire life cycle of electronic data, that is, the complete chain of data from generation, storage, verification to final use. In other words, blockchain certificates must not only be "stored" but also "certified". Only in this way can the reliability of the on-chain data be effectively guaranteed.
