Code and Experimental Data for “A Time-Quality Coordinated Matching Method for Decentralized Trading of Multi-source Homogeneous Data Assets”

This dataset contains the source code and experimental materials supporting the manuscript “A Time-Quality Coordinated Matching Method for Decentralized Circulation and Trading of Multi-source Homogeneous Data Assets.” The archive includes the Solidity implementation of Time-Quality Coordinated Matching (TQCM), internal control mechanisms, external batch baselines, Hardhat tests, replay-generation scripts, processed calibration summaries, experimental outputs, statistical results, and figure-generation code. Version 2 adds scalability replays at 80, 200, 400, and 800 events across five scenarios, ten seeds, and four mechanisms, together with completion-rate and out-of-gas boundary reporting. It also adds deterministic tests of candidate-access and consecutive-fill limits, including residual cancellation, order-state transition, and locked-asset release verification. The evaluation further covers effective-price formation, waiting compensation, seller-quality regulation, price protection, partial-fill updates, quality-input robustness, multi-seed mechanism comparison, on-chain execution cost, and parameter sensitivity. Third-party raw Binance BTCUSDT and FI-2010 data are not redistributed. Processed calibration summaries, replay inputs, results, and plotting inputs are included for direct reproduction.
