Research on the service implementation method of blockchain

Key terms

Term definitionBlockchain is a distributed database used to record transaction data and ensure data security and immutability through cryptography. Smart contract is a piece of code stored on the blockchain, which is automatically executed when predefined conditions are met. Appearance data Appearance characteristics of physical entities, such as the shape and color of vehicles. Transaction refers to any operation or data exchange performed on the blockchain. Service trigger refers to predefined conditions, which, when met, will trigger the execution of the corresponding service. Consensus mechanism The mechanism for nodes in the blockchain network to reach consensus, used to verify and add new blocks. Distributed ledger A database shared and synchronized on multiple nodes, blockchain is an example. Short answer question

In the blockchain service implementation method described in the present invention, how is the appearance data collected?

In the present invention, the appearance data can be realized by attaching a medium to the surface of the entity and solidifying it, and then collecting the entity appearance data on the medium. For example, nanomaterials can be attached to the surface of a vehicle, and the vehicle appearance information can be obtained by collecting the vehicle appearance data on the nanomaterial.

What role does the smart contract play in this service implementation method?

Smart contracts are stored on the blockchain. When the preset trigger conditions are met, the smart contract will be called and automatically execute the corresponding service operations. For example, when a vehicle accident is detected, the smart contract will be triggered to execute services such as accident liability determination and insurance claims.

What is the service trigger mentioned in the invention? Please give an example.

A service trigger refers to a predefined condition that, when met, triggers the execution of the corresponding service. For example, a vehicle collision can be used as a service trigger to trigger a vehicle accident handling service; a vehicle entering a specific area can be used as a service trigger to trigger a traffic guidance service.

How does the invention solve the problem of difficulty in confirming entity identity in traditional service models?

In traditional service models, entity identity confirmation usually relies on centralized institutions or databases, which are prone to the risk of information leakage or tampering. The present invention, by storing entity appearance data on the blockchain, ensures the authenticity and traceability of entity identity information, thereby solving the problem of difficulty in confirming entity identity in traditional service models.

What does the "multi-party participation" mentioned in the invention mean?

"Multi-party participation" refers to the joint participation of multiple nodes in the maintenance and data processing of the blockchain network. For example, in the vehicle accident liability determination service, multiple nodes can jointly analyze and determine the accident scene data to ensure the fairness and credibility of the results.

What is the "collaborative blockchain" mentioned in the invention?

"Collaborative blockchain" refers to a blockchain network maintained by multiple institutions or organizations. For example, a collaborative blockchain can be jointly built by automobile manufacturers, insurance companies, traffic management departments and other institutions for vehicle data sharing and service provision.

What does the "traffic congestion contract being triggered" mentioned in the invention mean?

"Traffic congestion contract being triggered" means that when the blockchain network detects traffic congestion, it will automatically trigger a pre-set smart contract to execute the corresponding traffic diversion service. For example, the optimal route can be planned for the vehicle based on real-time road conditions to alleviate traffic congestion.

What are the advantages of the "nanomaterials" mentioned in the invention in data collection?

Nanomaterials have the characteristics of small size and high sensitivity, and can collect physical appearance data more accurately. For example, attaching nanomaterials to the surface of a vehicle can more comprehensively collect information such as the three-dimensional shape and color of the vehicle.

What does the "reward" mentioned in the invention mean?

"Reward" refers to the incentives users receive when using blockchain services. For example, users can be rewarded for providing high-quality data or participating in service evaluation, thereby encouraging users to actively participate in the blockchain service ecosystem.

What does the "broadcast" mentioned in the invention mean?

"Broadcast" means sending information to all nodes in the blockchain network. For example, when a vehicle has an accident, the accident information can be broadcast to all nodes in the network so that other nodes can take corresponding measures in time.
