Popularization of blockchain traceability system: Yangcheng Lake hairy crabs realize "one crab, one code" traceable
As consumers' demand for food safety and transparency grows, the application of blockchain technology in the field of commodity traceability has gradually become a hot topic. Recently, the Yangcheng Lake Hairy Crab Association announced the official launch of the blockchain traceability system, realizing the full traceability of "one crab, one code", becoming a benchmark case for digital upgrades of agricultural products. This move not only enhances consumer trust, but also provides a reference for traceability of other agricultural products.
1. The core advantages of blockchain traceability system
The immutability and transparency of blockchain technology make it an ideal tool for product traceability. The Yangcheng Lake hairy crab "one crab, one code" system ensures the data is authentic and reliable through the following methods:
| Section | Record content | Technical Assurance |
|---|---|---|
| Breeding | Crab seedlings source, breeding waters, feeding records | Automatically upload data by IoT devices |
| Processing | Sorting time, weight specifications, quality inspection results | Blockchain timestamp evidence storage |
| logistics | Transportation temperature, transit location, delivery time | GPS+temperature and humidity sensor linkage |
| Sale | Dealer information, terminal retail price | Automatic verification of smart contracts |
2. Examples of consumer query data
The following is a randomly selected sample of Yangcheng Lake hairy crab traceability data:
| Traceability code | YCH20231015A58 |
|---|---|
| Breeding base | Yangcheng Lake East District Ecological Breeding Farm |
| Release date | March 20, 2023 |
| Fishing time | September 28, 2023 05:30 |
| Quality Inspection Report | Heavy metal content <0.01mg/kg |
| Logistics timeliness | Refrigerated transportation is below 8℃ |
3. Market response and industry impact
According to statistics from the Suzhou Municipal Market Supervision Bureau, the system has produced significant results within one week of its launch:
| index | Amplitude of change |
|---|---|
| Consumers scan code to query | Average daily 126,000 times |
| Number of complaints about counterfeit products | 67% year-on-year |
| High-end gift box sales | 42% month-on-month increase |
| Export order quantity | 23 new Southeast Asian orders |
This innovative model is triggering a chain reaction. Currently, six agricultural product production areas such as Dongting Lake hairy crabs and Liao ginseng have begun to test similar systems. The head of the Cold Chain Committee of the China Federation of Logistics and Procurement said that blockchain traceability technology will reshape the fresh food supply chain system, and the market size is expected to reach 8 billion yuan in 2024.
4. Future development trends
According to industry analysis, blockchain traceability will present three development directions:
1.Technology integration: Combined with 5G and AI quality inspection to realize real-time video traceability;
2.Unified standards: The Ministry of Agriculture and Rural Affairs is formulating national standards for traceability of agricultural products blockchain;
3.Ecological expansion: In the future, carbon footprint tracking function may be connected to meet ESG needs.
The president of Yangcheng Lake Hairy Crab Association said that in the next step, some blockchain nodes will be opened to third-party testing institutions to further enhance credibility. This innovation not only protects "safety on the tip of the tongue", but also provides a replicable model for the digital transformation of traditional agriculture.
