Networking method and device for blockchain-based smart contract resources

Abstract

The embodiment of the present application relates to a method and device for networking smart contract resources based on blockchain, and relates to the field of Internet technology, including: calculating the attribute groups of all resources and the spatial attribute LocationID of all nodes, and entrusting the new node to guide the node to initiate a pair The search for the LocationID of the new node guides the node to continuously learn and query the best node by using the topology structure associated between nodes, and finally converges to get the nearest adjacent node. The new node and the nearest node store the LocationID each other. After all nodes are added, the new The resource utilization start node converges to the target node through the topology structure associated between the nodes, and stores resources on the target node. In this application, resources and nodes are networked based on spatial locations, and attributes such as resource categories and available states are defined during the networking process. Using this networking method, smart contract resources stored in the blockchain can be realized Realize fuzzy search while searching based on time and location attributes.

Description

technical field [0001] The embodiment of the present application relates to the technical field of the Internet, in particular, to a method and device for networking smart contract resources based on blockchain. Background technique [0002] A smart contract is a computer protocol designed to disseminate, verify or enforce contracts in an informational manner. Smart contracts allow for trusted transactions without third parties, which are traceable and irreversible. In the blockchain, users can realize decentralized use of service resources through smart contracts, such as the "Resource Reflection Mechanism and Efficient Interoperability of Cloud-Terminal Fusion System" of the Key Laboratory of High Credibility Software Technology of the Ministry of Education of Peking University Technology" project includes the verification of the feasibility of controlling smart home devices through smart contracts. The smart home devices here include smart air purifiers, smart electric ...

AI Technical Summary

Problems solved by technology

Using the traditional blockchain networking method, due to the lack of a central index mechanism, it is difficult to search and access smart contracts, which brings great difficulties to resource search

On the other hand, due to the decentralized nature of smart contracts, the spatiotemporal attributes of resources cannot be directly obtained from the overall global query

Moreover, traditional networking methods often focus on the search for specified resources, but for smart contract resources, users only know the type of resources they need, and do not know all the companies (individuals) and geographical locations of the resources they need. , the ID of a specific resource, and the fuzzy search for resources cannot be realized

Smart contract resource search requirements that focus on spatiotemporal attributes cannot be directly applied to existing blockchain networking methods
