What is the essence of traceability in blockchain technology?

Chongqing Jinwowo analysis: the essence of traceability is information transmission, and the blockchain itself is also information transmission, data is made into blocks, private keys are generated according to algorithms, tampering is prevented, and then timestamps and other ways are used to form chains, which is just in line with the process production model of the commodity market.

Blockchain traceability technology includes the following:

1. One is RFID wireless radio frequency technology, which adds a logo with a chip on the product packaging, and the relevant information can be automatically collected and read when the product enters and exits the warehouse and transportation, and the flow direction of the product can be recorded on the chip;

2. One is ***, consumers only need to shoot the two-dimensional bridge code through the mobile phone with a camera, and they can query the relevant information of the product, and the records of the query will be kept in the system, once the product needs to be recalled, it can be directly sent to the consumer to achieve accurate recall;

3. There is also a bar code plus product batch information (such as production date, production time, batch number, etc.), and the production of enterprises in this way does not increase production costs.

Hello, blockchain technology is characterized by decentralization, non-tampering, and traceability, which makes blockchain traceability an effective means of accountability. In blockchain traceability, accountability can be pursued through the following methods:

1.Through the immutability of the blockchain, transaction records and operation records can be traced, so as to determine the identity and behavior of the person responsible.

2.Building smart contracts on the blockchain can automate contract execution and supervision, thus avoiding human violations.

3.Establish a consortium chain to ensure the authenticity and legitimacy of data through multi-party joint supervision and review, so as to reduce the violations of those responsible.

4.Establish a blockchain traceability platform to integrate the data and information of each link to form a complete traceability chain, so as to trace the behavior of the responsible person.

In short, blockchain traceability is an effective and reliable means of accountability, which can reduce the violations of responsible persons and ensure social justice and fairness through the characteristics of decentralization, non-tampering, and traceability. Celery.

Hello, blockchain traceability is a method of tracing items or information through blockchain technology. When it comes to accountability, blockchain traceability can provide reliable data** and tamper-proof data records to more accurately determine liability.

First of all, blockchain traceability can record the ** and flow direction of items or information. Through the decentralized nature of the blockchain, each participant can record and verify the data, thus ensuring the authenticity and reliability of the data. In the event of a liability dispute, the responsible party can be determined by querying the blockchain records.

Secondly, blockchain traceability can record the processing process of items or information. For example, in the field of food safety, the production, processing, transportation and sales process of food can be recorded through the blockchain, so that the food can be traced back to the food and processing process, and the responsible party can be more accurately determined in the event of a food safety incident.

Finally, blockchain traceability can automate liability traceability. Through technologies such as smart contracts, liability rules and punishment mechanisms can be preset on the blockchain, and liability traceability and punishment can be automatically executed, thereby reducing the possibility of human intervention and misjudgment.

Blockchain traceability can provide reliable data** and tamper-proof data records, so that accountability can be held more accurately. With the continuous development and application of blockchain technology, blockchain traceability will play an increasingly important role in various fields.

1 Blockchain traceability can be held accountable.

2 Blockchain technology is a distributed database technology that can record, store, verify, and transmit data while ensuring that the data is immutable and decentralized.

For events that require traceability responsibility, it is only necessary to find the relevant blockchain records to determine the behavior and responsibility of the relevant personnel.

3 For the accountability of blockchain technology, it is also necessary to formulate corresponding legal regulations and policy measures.

In addition, it is also necessary to pay attention to data privacy and security issues to ensure the legal use of blockchain data and protect the rights and interests of users.

Blockchain traceability technology can achieve the effect of accountability by storing and recording the transaction data generated by the relevant participants, as well as through the smart contract confirmation function on the distributed ledger. Blockchain traceability technology can gain insight into the process of each loss in the chain, which helps participants to determine responsibilities more accurately, and ensure timely and effective fulfillment of responsibilities from the perspective of preparation.

With the continuous application of blockchain technology in the real field, more and more technology companies have proposed their own underlying technology frameworks, as well as industry solutions in vertical fields, the English name of the BaaS platform is BlockchainAsaService, which is directly translated as BlockchainAsaService, referred to as BaaS. In fact, BaaS is a new type of cloud service that combines blockchain technology, which refers to embedding the blockchain framework into the cloud computing platform.

Blockchain mainly uses () means to achieve the traceability of data with high discretion.

a.Time group Zheng stamp.

b.Consensus mechanism.

c.Smart contracts.

d.Digital signatures.

Correct answer: ab

Answer analysis: The blockchain uses timestamps, consensus mechanisms and other technologies to realize the functions of data non-tampering and traceability, which provides technical support for the establishment of a cross-institutional traceability system.

The traditional traceability system generally uses a centralized ledger model, which is recorded and stored in isolation by various market participants, which is an information island model. In the centralized ledger model, who as the center to maintain the ledger has become the key to the problem, whether it is the source of the enterprise, or the channel provider to keep, because they are themselves stakeholders in the circulation chain, when the ledger information is not conducive to itself, it is possible to choose to tamper with the ledger or falsely claim that the ledger information is lost due to technical reasons.

Under the silo model of letter rubber interest rate change, each participant in the market maintains a self-maintained ledger, which is commonly known as the ledger, and is named after being electronic. Whether it is a physical ledger or an electronic purchase, sale and inventory system, the owner can tamper with it at will or make it up centrally. The real-time reconciliation capability of blockchain in registration and settlement scenarios, and the ability of tamper-proof and time-stamping in data storage scenarios provide powerful tools for scenarios such as traceability, anti-counterfeiting, chain finance and chain management.

The industry-specific application design of Hongqiao Hi-Tech Blockchain forms a closed-loop self-verification capability of on-chain data through the integrity and relevance of trusted transaction data. It is used to verify the authenticity of digital documents and transaction records, as well as to track products and commodities throughout the chain. These certificates are generally used by enterprises and financial institutions in the evaluation and processing of credit and loans.

In the heat wave of "embracing blockchain" in 2018, who can take the lead in finding application scenarios and launching landing projects has become the most important part of the competition.

Among them, traceability and anti-counterfeiting are considered to be one of the most promising areas for blockchain landing, and it is also the first field for giants to compete for blockchain technology landing. In China, Chongqing, Hangzhou and other cities have taken the lead in "testing the waters" of the application of blockchain in food traceability; E-commerce giants such as Tmall and JD.com have also used blockchain technology in their respective systems to trace the source of goods and prevent counterfeiting.

Compared with traditional traceability and anti-counterfeiting, what are the advantages of blockchain traceability? What pain points can blockchain technology solve in the traceability and anti-counterfeiting business? Can blockchain technology open a new chapter in the traceability and anti-counterfeiting business?
