Block-CITE: A Blockchain-Based Crowdsourcing Interactive Trust Evaluation
This paper proposes Block-CITE, a Blockchain-based Crowdsourcing Interactive Trust Evaluation method, to enhance the security, efficiency, and flexibility of industrial trademark management. It uses a dual-blockchain structure (TaskChain for tasks, RepuChain for reputations) and smart contracts to decentralize functions previously handled by a centralized Trademark Management Center (TMC). The system leverages crowdsourcing for trademark examination, where requesters deposit funds, TMC selects workers based on reputation, and both parties score results, with all hashes stored on the blockchain for immutability. Security analysis confirms resilience against common blockchain attacks (e.g., 51% attack), and experimental results demonstrate superior transaction throughput, lower network latency, and reduced storage overhead compared to single-blockchain or non-blockchain baselines.

Blockchain Architecture
Block-CITE utilizes a dual-blockchain structure: TaskChain for storing trademark examination tasks and RepuChain for worker reputations. This separation optimizes performance by isolating frequently accessed hot data (tasks) from less frequently accessed cold data (reputations) and enhances security through decentralized, immutable record-keeping. The hash values of sensitive trademark materials are stored on-chain, while the materials themselves are managed off-chain (e.g., IPFS) to maintain privacy and manage storage overhead.
Crowdsourcing Mechanism
The system implements a crowdsourcing model where requesters submit trademark applications, and the TMC (acting as an orchestrator, not a central authority) assigns tasks to qualified workers based on their on-chain reputation. Workers perform examinations, and both requesters and the TMC score their performance, updating the worker's reputation on RepuChain. This decentralized approach ensures transparency, accountability, and incentivizes good behavior, mitigating issues like false-reporting and free-riding.
Security & Trust Evaluation
Block-CITE enhances security through several mechanisms: deposits deter malicious behavior (sybil, DDoS, false-reporting), hash values of all critical data (tasks, results, reputations) are immutably stored on the blockchain to prevent denial, and a dynamically adjusted reputation threshold ensures only qualified workers are selected. Formal security analysis, including simulations of a 51% attack under a Proof-of-Work (PoW) consensus, demonstrates that the probability of an attacker forging the longest chain is exponentially small, confirming the robustness of the scheme.
Performance Optimizations
The dual-blockchain architecture significantly improves performance by separating 'hot' (TaskChain) and 'cold' (RepuChain) data, reducing network traffic and query latency. Experimental results show Block-CITE achieves higher transaction throughput (up to 64.7% increase) and lower network latency compared to single-blockchain systems. Storage overhead is also reduced by 42.66% compared to centralized systems, as only hash values are stored on-chain, while large materials are managed off-chain, ensuring scalability for industrial applications.

Dual-Chain for Scalability
Our experimental results confirm that the dual-blockchain structure in Block-CITE is not merely a theoretical advantage but translates into tangible performance gains. By diverting network traffic related to task information and reputation across two distinct chains, we drastically reduce congestion. This leads to a 64.7% increase in transaction throughput and significantly lower transaction latency, demonstrating how architectural decisions directly impact operational efficiency in decentralized systems.

Your Enterprise AI Implementation Roadmap
A phased approach to integrate Block-CITE principles into your operations, ensuring a smooth transition and maximum impact.
Phase 1: Proof-of-Concept Development
Build a minimum viable product (MVP) incorporating TaskChain and RepuChain, core smart contracts, and basic requester/worker interaction. Focus on key cryptographic components and initial blockchain setup (e.g., Hyperledger Fabric).
Phase 2: Pilot Program & Scalability Testing
Deploy the MVP in a controlled pilot environment with a select group of industrial partners. Conduct rigorous testing for transaction throughput, latency, and storage overhead under varying load conditions. Integrate off-chain storage solutions (e.g., IPFS).
Phase 3: Security Audits & Regulatory Compliance
Engage third-party security experts to perform comprehensive audits of the blockchain protocols and smart contract code. Ensure full compliance with relevant industrial and commercial regulations for trademark management.
Phase 4: Full-Scale Deployment & Ecosystem Expansion
Gradually roll out Block-CITE to a broader user base. Develop advanced features such as sophisticated reputation models, AI-powered examination assistance, and cross-chain interoperability for future enhancements.
