本論文旨在探討並優化基於區塊鏈智能合約的再生能源憑證管理系統，以減少其Gas消耗。再生能源憑證管理系統是實現可持續能源交易和監管的重要工具，而區塊鏈技術為該系統提供了透明性、安全性和不可篡改性。然而，由於智能合約在區塊鏈上的運行需要消耗Gas，因此如何降低Gas消耗成為了本研究的重點。

本研究在深入分析現有再生能源憑證管理系統的基礎上，提出了批量驗證功能的優化設計。通過將原有的單次驗證模式改為批量驗證，本研究旨在減少每次驗證過程中的Gas消耗。論文採用模擬測試方法，通過不同驗證邏輯複雜度、數據長度和驗證數量的組合，對優化後的系統進行了全面評估。實驗結果表明，批量驗證在大多數情況下顯示出顯著的Gas消耗減少效果，特別是在驗證數量較大和數據長度適中的情況下，其Gas消耗顯著低於原有模式。

本研究的結果為區塊鏈技術在再生能源憑證管理中的應用提供了新的思路和方法，並證明了通過合約優化設計可以有效減少Gas消耗，提升系統的經濟性。這為未來的再生能源市場提供了更具競爭力的技術支持。

This paper aims to explore and optimize a blockchain-based renewable energy certificate (REC) management system, with a focus on reducing its Gas consumption. A REC management system is a critical tool for enabling sustainable energy trading and regulation, and blockchain technology provides the system with transparency, security, and immutability. However, since executing smart contracts on the blockchain incurs Gas costs, reducing Gas consumption has become the focal point of this research.

Based on an in-depth analysis of existing REC management systems, this study proposes an optimized design featuring batch verification functionality. By replacing the original single verification process with batch verification, this research seeks to reduce Gas consumption during each verification procedure. The paper employs simulation testing methods, evaluating the optimized system through various combinations of verification logic complexity, data length, and verification quantity. Experimental results demonstrate that batch verification significantly reduces Gas consumption in most cases, particularly when the number of verifications is large and data length is moderate, with Gas consumption considerably lower than the original model.

The findings of this study provide new insights and methods for applying blockchain technology in REC management and demonstrate that smart contract optimization can effectively reduce Gas consumption, thereby enhancing the system's economic efficiency. This offers more competitive technological support for the future renewable energy market.
