System modeling demonstrates improved throughput and reduced ledger growth in academic credential systems, highlighting a scalable approach for high-volume digital issuance.
Key Points
Design and evaluate a performance-optimized blockchain architecture capable of handling high-volume academic credential issuance without incurring ledger bloat or transaction delays.
Engineered a modular architecture separating certificate preprocessing from blockchain anchoring via a microservice-based parallel processing pipeline and distributed off-chain storage.
Implemented Merkle-tree-based batch anchoring to aggregate multiple certificates into a single on-chain transaction.
Formulated an analytical evaluation model combining queueing theory and blockchain performance parameters to evaluate system behavior across varying workloads.
Batch anchoring significantly increased transaction throughput by consolidating multiple digital certificate records into single blockchain transactions.
The architecture maintained low confirmation latency under elevated issuance workloads compared to conventional individual-transaction approaches.
Distributed off-chain storage coupled with Merkle root anchoring minimized on-chain ledger growth while preserving full credential auditability and verifiability.
