## 4 Results
Among the key military aspects of long-term viability, there is a need to migrate to quantum-resistant cryptographic algorithms [72], which has been stressed by several studies regarding futureproofing against emerging quantum computing threats [51; 62]. The evolution of blockchain implementation in military supply chain management is promising for its potential to revolutionize operational efficiency, security, and transparency. While challenges remain regarding scalability, energy efficiency, and interoperability, innovative solutions such as sharding, smart contracts, and energy-efficient consensus mechanisms provide promising ways forward. Further development of these solutions, together with emerging research into quantum resistance and optimization techniques, places blockchain technology at the core of developing resilient, secure, and efficient military logistics systems. **[RQ3]. **_What role can smart contracts play in improving maintenance management frameworks within military operations?_  
The technical functionalities of smart contracts in managing military maintenance reveal sophisticated implementations that fundamentally enhance operational effectiveness and system reliability beyond basic automation. Smart contracts also demonstrate advanced capability in integrating with predictive analytics systems through sophisticated sensor networks, thus enabling the real-time monitoring of equipment performance parameters while automatically triggering maintenance protocols from predictive algorithms [78]. This integration has been shown, through research, to enable dynamic scheduling of maintenance based on actual equipment conditions rather than at fixed intervals, with an effective method of preventing equipment failures while optimizing maintenance resources [93]. It enables advanced sensor data processing through machine learning algorithms and automatically updates maintenance parameters using smart contracts based on performance trends. This technical methodology realizes real-time performance monitoring and dynamic adjustment of maintenance triggers and multiple sensor input correlation, enabling predictive failure analysis and prevention. The sophistication of these functionalities ensures proactive maintenance intervention well before critical failures occur and enhances military readiness significantly. Advanced smart contract implementations have many capabilities in autonomous decision support for maintenance operations, with research showing their implementation of complex decision trees that automatically evaluate equipment criticality levels, operational status, mission requirements, resource availability, and environmental constraints. This technical implementation has proven effective in automatically prioritizing maintenance activities according to their operational importance and resource constraints [61]. It carries out complex decisions on time maintenance and resource allocation without interference from human beings while complying with military maintenance standards [80]. Integration capabilities of smart contracts can reach several military systems at the same time. Research has shown that implementation is successful when connecting maintenance management systems with supply chain management [67], resource allocation [69], personnel management, and mission planning systems. Such broad integration allows the automation of maintenance-related processes across various operational domains. The technical implementation has effectively maintained data consistency and operational coordination across diverse military systems [82]. The security of smart contracts has evolved to include multi-signature requirements for key decisions regarding maintenance, permissions, role-based access control, encrypted data storage and transmission protocols, and automated security policy enforcement. Research proves that these security implementations effectively protect sensitive maintenance data while preserving the potential for authorized access and operational flexibility [91].
