Besu-EduNet: A Longitudinal Operational Dataset of a Hyperledger Besu QBFT Consortium Blockchain

This dataset supports the longitudinal operational measurement study of Besu-EduNet, a permissioned Hyperledger Besu QBFT consortium blockchain operated by the University of West Attica for educational and applied-research purposes. It contains the complete block-level record for blocks 0–6,147,305 (6,147,306 blocks) collected over approximately 382 days, together with derived operational summaries, detected inter-block gaps, classified service interruptions, proposer-fairness measurements, validation output, and reproducibility scripts. The dataset contains on-chain block metadata only: block number, timestamp, proposer address, gas used, and transaction count. It contains no transaction payloads, contract state, personal data, or user-identifying information. The accompanying scripts document the JSON-RPC extraction procedure and reproduce the principal validation and derived measurements used in the associated manuscript. Version 1.1.0 adds reproducibility artifacts for temporal proposer-participation analysis, including hourly proposer-participation windows, deficient-window episode detection, validator-set transition analysis, and the corresponding visualization. The underlying block-level dataset is unchanged from Version 1.0.0.
