This research presents a blockchain-based log management system that integrates an LLM-assisted query mechanism to enhance security and provide contextual insights into storage event logs. The modules for decentralized storage event logs, including registered users, log retrieval and storage, and log auditing, are built on a blockchain deployed via an Ethereum smart contract, which enhances the following. EdDSA-based digital signatures (Ed25519) are applied to audit log events to ensure integrity. Additionally, log files are encrypted using asymmetric encryption (Curve25519) to protect confidentiality, while the decentralized IPFS (InterPlanetary File System) stores log file metadata on the blockchain, reducing storage size. In the querying module, an LLM-based natural-language model is integrated. Moreover, we organize the logs into semantic groups and hourly summary tables for LLM-assisted analysis. Users can analyze log data without complex query rules. The experiment covers four evaluations: First, functional correctness. The storage event log modules correctly support secure log management and verify log audit. Second, IPFS delivers practical performance with average upload times (0.41 s) and download times (0.19 s). Third, blockchain operations require reasonable gas usage. Fourth, the Llama 3.1 (8B) achieves the best querying performance, with Correctness (0.80), Faithfulness (0.53), and Helpfulness (0.62) supporting practical log analysis.
