Multi-layer Blockchain Ledger for Logarithmic Verification

The patent divides the blockchain verification process into multiple hierarchical layers. The first layer performs SPV verification on individual data records, while the second layer performs integrity verification on aggregated data blocks. This segmentation allows different verification types to operate at appropriate granularities, improving overall verification efficiency while reducing time complexity from linear to logarithmic for large-scale integrity verification.

The patent introduces a vertical hierarchical dimension to the traditional single-layer blockchain structure by creating a multi-layer verification system. The first layer handles record-level verification and the second layer handles block-level integrity verification, adding a dimensional aspect to verification operations that enables parallel processing and reduces the time complexity of large-scale verification tasks.

The patent merges multiple functions into the data block structure by incorporating both original transaction data and verification-related data (such as Merkle roots, block hashes, and verification parameters) within the same block. This combining increases the information capacity of each block, allowing it to serve both storage and verification purposes simultaneously, thereby improving efficiency without proportionally increasing complexity.

The patent designs data blocks to serve multiple functions: storing transaction data, containing verification parameters, and enabling both SPV and integrity verification operations. This multi-functionality increases the utility and information capacity of each block, allowing the system to perform diverse operations without requiring separate specialized structures for each function.
