Replication Data for: Scalable On-Chain Storage Mechanism for DApps with a Throughput Trade-Off on a Permissionless Blockchain

This repository contains 64 MiB binary files representing partitions of Bitcoin’s unspent transaction outputs (UTXOs). The data is classified into three logical categories — IM, ML, and MH — based on criteria defined in a simulation model. Each file (*.bin) contains records serialized in CSV format and padded with zeros (0x00) to reach exactly 64 MiB. The structure of each record follows the schema below: tx_id,output_index,amount,scriptPubKey,block_height,tx_size,classification tx_id: transaction identifier output_index: index of the output within the transaction amount: value of the UTXO scriptPubKey: locking script in hexadecimal format block_height: block number where the UTXO was confirmed tx_size: size of the transaction in bytes classification: assigned label (IM, ML, MH) These chunks were generated using a Python script that processes the original SQLite database (utxo_classification.db) in blocks of 50,000 rows per iteration. Each classification is processed independently and streamed to disk in binary chunks to support low-memory operation. This dataset is intended to support reproducible research on data availability, UTXO distribution, and scalable simulations of decentralized networks.
