Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing land parcel surveying methods and land descriptions are not compatible with the restrictive syntax requirements of blockchain networks, making it difficult to execute smart contracts related to land parcels efficiently.
Innovation Solution
The implementation of S2 cells and non-fungible tokens (NFTs) allows for the mapping and representation of land parcels in a digital format compatible with blockchain networks, enabling the execution of smart contracts related to land parcels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional natural language land descriptions are used in land deeds, then reliable land boundary and area information can be generated, but the data cannot be efficiently processed by smart contracts due to syntax incompatibility
Solution Approach 1:
The patent transforms land description data from natural language format into structured coordinate data format that is compatible with blockchain smart contracts. This parameter change in data representation enables automated processing while maintaining the reliability of land boundary and area information.
Solution Approach 2:
The patent introduces an intermediary data transformation process that converts traditional land survey data into a format suitable for blockchain. This intermediary layer bridges the gap between reliable natural language descriptions and machine-executable smart contract syntax.
2Productivity
If structured coordinate data is used to represent land parcels, then smart contracts can be efficiently executed, but the complexity of data formatting and conversion increases
Solution Approach 1:
The patent segments the land parcel representation into discrete coordinate points that can be independently processed by smart contracts. This segmentation simplifies the data structure, making it easier to format and convert while maintaining execution efficiency.
3Reliability
If detailed land boundary information is stored on blockchain, then land ownership and service verification can be accurately tracked, but the storage requirements and network load increase
Solution Approach 1:
The patent extracts only the essential coordinate data needed for land boundary verification and stores it on the blockchain, while leaving detailed natural language descriptions off-chain. This extraction reduces the quantity of data stored on the blockchain while maintaining verification accuracy.
Data Source
AI summary
Implementations set forth herein relate to utilizing S2 cell values to characterize arbitrary portions of land parcels and storing the S2 cell values in association with a non-fungible token (NFT) that is stored on a blockchain network, or other peer-to-peer (P2P) network. The S2 cell values can be generated by iteratively using bounding shapes that are selected to extend over at least a portion of a respective parcel of land, and each bounding shape can be represented by one or more single dimensional values. When a generated bounding shape extends outside of a boundary of a parcel of land, subcells of the bounding shape can be generated to define further bounding shapes. A land NFT for the list of cell values for the bounding shapes can be stored at a blockchain address for an authenticated owner of the parcel of land.
