Answers to short answer questions

The alliance blockchain business network is composed of multiple alliance nodes, each of which corresponds to a circulation link in the product supply chain, and jointly maintains a decentralized distributed ledger. Unlike traditional centralized systems, it does not rely on a single trusted organization, and data storage is more secure and reliable.

Alliance nodes are divided into master alliance nodes and slave alliance nodes. The master alliance node is responsible for initiating consensus, generating new blocks and writing data into the blockchain; the slave alliance node is responsible for verifying the data blocks generated by the master alliance node, and writing the data into its own blockchain after verification.

After the alliance node collects product data, the master alliance node uses the consensus mechanism to generate a new block, and fills the product data into the block after processing it with the signature and hash algorithm, and then synchronizes the block to other slave alliance nodes for verification and writing.

Metadata is an index of block data, which contains information such as block identifiers and product identifiers, and is used to quickly locate and query product data on the blockchain.

The consensus mechanism ensures that all alliance nodes reach consensus on the data, ensures the accuracy and reliability of the data, and prevents data from being tampered with.

Point-to-point transmission technology is used for data synchronization between alliance nodes, without the need for centralized servers, which improves data transmission efficiency and security.

Verifying alliance nodes is to ensure the authenticity and security of data. By comparing the consensus results, malicious alliance nodes can be identified and eliminated to prevent malicious behavior from destroying data integrity.

Consumers can use mobile terminal APP to scan the unique identifier on the product and connect to the alliance blockchain system to query the detailed information of the product in each circulation link.

In the drug traceability system, the alliance node in each circulation link records the relevant information of the drug, and uses blockchain technology to ensure that the data cannot be tampered with, thereby ensuring the authenticity and reliability of the drug information.

Compared with the traditional system, the alliance blockchain product traceability system has the advantages of decentralization, data security and reliability, transparent and traceable information, and high credibility.

Key Glossary

Definition of terms Alliance blockchain A blockchain network that requires authorization to participate, suitable for data sharing and collaboration between institutions. Alliance node Participants in the alliance blockchain network have independent data storage and processing capabilities. Master Alliance Nodes are nodes elected by the consensus mechanism to generate new blocks. Slave Alliance Nodes are nodes responsible for verifying and storing data blocks generated by the Master Alliance Node. Product Data Data describing the circulation of products in various links of the supply chain. Metadata Index of block data, including information such as block identifiers and product identifiers. Consensus Mechanism Algorithms that ensure that all alliance nodes reach a consensus on data. Peer-to-peer transmission is a technology that does not rely on centralized servers and directly transmits data between nodes. Signature Algorithms Encryption technology used to verify the source and integrity of data. Hash Algorithms Algorithms that convert data of any length into a fixed-length hash value to ensure that the data has not been tampered with.
