Educational cooperation in higher education offers valuable opportunities for students and institutions alike. However, it also introduces significant challenges, particularly regarding student enrollment processes. Traditional centralized systems managing this task can pose issues around authority, transparency, accountability, security, cost, often hindering scalability sustainable growth. This paper the Cross-Institutional Blockchain Enrollment System (BCHEEN), a novel decentralized platform designed to streamline enhance cross-institutional Un-like existing solutions, BCHEEN employs unique hybrid architecture that leverages blockchain technology ensure transparency security while maintaining through innovative off-chain data management using “replicate when used” approach. The was prototyped as permissioned Hyperledger Composer framework evaluated functional, performance, analyses tools such Cucumber Caliper. Evaluation results show achieved peak throughput of 18 tps at send rate 47 tps, with an average latency 4.32 s under same conditions, demonstrating its reliability. Furthermore, computational cost analysis highlights efficiency approach reducing storage overhead preserving integrity. BCHEEN’s practical impact includes streamlining processes, administrative costs, fostering secure, scalable, transparent inter-institutional collaboration. These contributions position transformative tool education, supporting policy advancements promoting resilience sustainability educational practices.

In the dynamic landscape of tech industry, escalating requirement for swift and secure data transmission has catalyzed innovation in integrated communication systems. Free-Space Optics (FSOs) emerged as a promising contender optical communications. While conventional fiber systems can achieve bit rates up to 40 Gbps with proper design, they are limited primarily by electronics rather than semiconductor laser capabilities. This study presents an framework that combines FSOs, blockchain technology, sensor networks address challenges transmission, security, environmental adaptation. analyzes FSOs system performance through Quality (Q) Factor Bit Error Rate (BER), comparing without Erbium-Doped Fiber Amplifiers (EDFAs) across various (8, 12, 16, 20 Gbps) distances (5-25 km). To enhance security reliability, architecture is incorporated smart contracts InterPlanetary File System (IPFS) storing validating results generated from simulation. Additionally, this explores design network models technology investigating how distributed arrays be theoretically systems, testing focused on implementation.
