logistics, and sales, creating challenges for trusted data sharing, privacy protection, and real-time traceability across distributed supply-chain information systems. Conventional single-chain blockchains suffer from limited scalability, data redundancy, and low retrieval efficiency, making them inadequate for high-frequency full-process information management. This study proposes a multi-chain blockchain framework for trusted full-process information management of fruit and vegetable supply chains. The framework integrates traceability, enterprise, notary, and regulatory chains to support hierarchical data management and privacy isolation. A reputation-based notary node election mechanism and a threshold-signature scheme based on Shamir secret sharing are designed to enhance cross-chain security and distributed regulatory consensus. To improve retrieval efficiency, a Cuckoo-Augmented Merkle Tree (CMerkle) and a skip-list-based block index are developed. Simulation results show that all malicious nodes were restricted by the 19th round, signature aggregation required 70.16 ms in a 500-node setting, and CMerkle achieved retrieval speedups of 14.7 and 153 times at data scales of 500 and 10,000 records, respectively. The framework supports trusted data governance, real-time traceability, privacy-preserving sharing, and regulatory decision supp","MDPI Computers 15(8):549 2026年8月21日","2026-08-21T00:00:00Z","论文",10,false,74,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},18,20,16,12,8,1,"论文提出多链区块链框架提升果蔬供应链效率，性能数据亮眼，但应用场景具体，影响范围有限。",[25],{"name":10,"url":6},[27,28,29,30,31,32,33],"果蔬供应链","多链区块链","CMerkle","阈值签名","Shamir秘密共享","MDPI Computers","北京工商大学",[],{"status":36,"locked":14,"version":37,"method":38,"evidence":39},"needs_review","2026-10-22.2","rules",{"candidates":40,"agricultural_evidence":14,"reason":41},[],"农业相关性需要复核",[43,44],"北京工商大学 多链区块链 果蔬供应链 Shamir秘密共享","北京工商大学 多链区块链","北京工商大学多链区块链果蔬供应链Shamir秘密共享-876",0,"2026-08-23T00:08:13.547080Z",{"total":46,"page":22,"page_size":22,"items":49},[]]
