Research Guide for Blockchain Asset Verification System

Glossary

Term Definition Blockchain A distributed database that stores data in blocks, each block contains the hash value of the previous block, forming an immutable chain structure. Distributed Ledger Technology (DLT) A consensus mechanism for replicating, sharing and synchronizing digital data between multiple nodes, without a central administrator or centralized data storage. Merkle Tree A tree-like data structure in which each non-leaf node is the hash value of its child node, often used to verify the integrity of data. Hash An algorithm that converts data of any length into a fixed-length string, often used for data encryption and integrity verification. Asset Attestation The process of proving the authenticity and ownership of an asset by collecting and verifying asset information. SKU Stock Keeping Unit A unique code used to identify and track products. Trusted Device In an asset proof system, an authorized and authenticated device used to collect and verify asset information. Originator Identification Information Information used to identify the owner of an asset. Distributed Storage: A storage method that stores data in multiple physical locations to improve data reliability and availability. Verifier: In an asset proof system, a person or organization responsible for verifying asset information and ownership. Short answer question

What technology does the system use to ensure the security of asset information?

The system uses blockchain and Merkle tree technology to ensure the security of asset information. The decentralized and tamper-proof characteristics of blockchain ensure the transparency and traceability of information, while Merkle tree is used to verify the integrity of data.

What role do trusted devices play in the asset verification process?

Trusted devices are responsible for collecting and verifying asset information during the asset verification process. They can be devices such as smartphones and tablets, through which users can collect pictures, locations, times, and other information of assets and upload them to the blockchain.

How does the system verify the authenticity of assets?

The system verifies the authenticity of assets by comparing the asset information submitted by users with the information stored on the blockchain. When an asset is registered, the system generates a unique identifier and stores it on the blockchain along with the asset information. When the authenticity of an asset needs to be verified, the system will compare the information submitted by the user with the information stored on the blockchain. If they match, the asset is considered to be authentic.

How does the system handle asset information that cannot be stored on the blockchain?

For large asset information that cannot be stored on the blockchain, such as pictures or videos, the system will store it in a distributed storage system and record a link to the storage location on the blockchain.

When an asset is transferred, how does the system update the ownership information of the asset?

When an asset is transferred, the verifier collects the information of the transferor and the transferee and uploads it to the blockchain together with the asset information. The system verifies whether the transferor has ownership of the asset and updates the ownership information of the asset after confirmation.

How does the system ensure the accuracy of the verified information?

The system relies on the reliability of trusted devices and verifiers to ensure the accuracy of the information. Trusted devices need to be authorized and authenticated, and verifiers also need to be authenticated.

How do users use the system to query asset information?

Users can use the query interface provided by the system to enter relevant information, such as asset identifiers or owner information, to query asset information.

What are the potential application scenarios of this system?

The system is suitable for various scenarios where asset tracking and management are required, such as supply chain management, art traceability, real estate transactions, etc.

What are the advantages of this system compared with traditional asset verification methods?

Compared with traditional asset verification methods, this system has higher security, transparency and efficiency. The use of blockchain technology can prevent information from being tampered with, while improving the traceability of information.

What is the future development direction of the system?

In the future, the system can be combined with technologies such as the Internet of Things and artificial intelligence to achieve more intelligent asset management and verification. For example, asset information can be automatically collected using IoT devices, and asset data can be analyzed using artificial intelligence technology to provide more accurate asset evaluation and prediction.
