What is a Mode?
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...

This study introduces a blockchain system for secure, massive data sharing using off-chain storage and identity controls. Analysis shows agricultural cold chain logistics efficiency requires infrastructure and management improvements for optimal resource allocation.
Area of Science:
- Computer Science
- Data Science
- Supply Chain Management
Background:
- Blockchain systems face challenges with massive data storage and transaction authority in data sharing scenarios.
- Existing solutions often incur high costs due to large data volumes within blocks.
- Ensuring confidentiality and controlled access to transaction data is crucial for diverse participants.
Purpose of the Study:
- To propose a novel blockchain system for controllable sharing of massive data.
- To address the limitations of on-chain storage for large datasets.
- To enhance data security and confidentiality through identity authentication and channel mechanisms.
Main Methods:
- Designed a blockchain system model integrating consortium and private chain concepts.
- Reconstructed block data structures to optimize storage.
- Implemented off-chain storage using InterPlanetary File System (IPFS) technology.
- Introduced identity authentication and channel mechanisms for access control.
Main Results:
- The proposed system effectively manages massive data storage and transaction authority.
- Off-chain storage significantly reduces the cost associated with large data blocks.
- Identity authentication and channel mechanisms ensure data confidentiality and isolation.
- Analysis of agricultural cold chain logistics (2017-2021) indicates efficiency above 0.9, suggesting effective resource allocation.
- Periods with efficiency below 1 highlight the need for strengthened infrastructure, technical support, and management in cold chain logistics.
- Total factor productivity in agricultural cold chain logistics (2018-2021) remained high, driven primarily by technical efficiency improvements.
Conclusions:
- The developed blockchain system offers a scalable and cost-effective solution for massive data sharing.
- The integration of IPFS and access control mechanisms enhances data security and usability.
- Agricultural cold chain logistics require strategic investments and improved management to overcome inefficiencies and optimize resource utilization.
- Technical advancements play a pivotal role in boosting overall productivity within cold chain logistics.
