Blockchain: Research and Applications

AI Summary

To address the challenges of trustworthy data sharing and governance in multi-stakeholder collaboration, this paper proposes a blockchain-empowered hierarchical information system architecture, introducing the novel “consensus-contract-provenance” tripartite coordination mechanism and supporting lightweight, dynamically scalable consortium blockchains. Methodologically, it integrates smart contracts, zero-knowledge proofs, decentralized identifiers (DIDs), and microservice-based information middleware to decouple business logic from data storage, enabling verifiable, auditable, and tamper-proof cross-domain interactions. In governmental and healthcare pilot deployments, data reconciliation time decreased by 76%, and cross-institutional audit efficiency improved by 3.2×; the system supports elastic scaling to tens of thousands of nodes. This work overcomes the trust bottleneck inherent in centralized governance models and establishes a reusable technical paradigm for information ecosystem governance in multi-organizational collaboration scenarios.
