This invention belongs to the field of blockchain technology, specifically relating to a semantic identifier blockchain retrieval method and system for large-scale distributed data. This invention designs a unified semantic identifier model, mapping data records from different sources and in different formats to multi-level scalable semantic paths. It constructs a MIR tree forest, integrating the organization of Trie and the verifiability of Merkle, with each scenario as the root. Only the root hash of each scenario or its aggregate root is maintained in the block header, thereby achieving overall constraint on the state of large-scale off-chain semantic indexes while maintaining lightweight on-chain storage overhead. Simultaneously, this invention designs corresponding index traversal and verification object construction mechanisms around various semantic retrieval modes, enabling clients to verify the correctness of target records with only limited path and node hash information. This provides a new technical path for unified semantic management and efficient verifiable retrieval of multi-source heterogeneous data in the HSB environment.
