Financial Management and Data Sharing of Enterprise Engineering Projects Based on Blockchain Technology

ABSTRACT The objective of this paper is to investigate how blockchain technology can be utilized in the financial oversight and data distribution for corporate construction projects, with the goal of enhancing the openness, productivity, and safety of financial processes. The paper involves creating a blockchain‐based financial management and data sharing framework that incorporates smart contracts to enable automated financial transactions and to establish a collaborative data sharing system among multiple parties. The experimental results show that compared with algorithms like Delegated Byzantine Fault Tolerance (DBFT) and Byzantine Fault Tolerance (BFT), the model algorithm proposed in this paper has lower communication costs. Specifically, in an environment with 200 users, the communication cost is 113.21 bytes. This is lower than the 147.05 bytes required by DBFT and much lower than the 214.44 bytes needed by the BFT algorithm. In terms of throughput, this algorithm is close to 1, and the throughput is 1 when there are 200 users, which is better than BFT's 0.892. In terms of delay, the average delay is 5.83 s, which is significantly lower than BFT's 15.22 s. In terms of packet loss rate, it is 0.053 for 10 nodes, which is significantly lower than 0.280 for BFT. To sum up, the model in this paper shows significant advantages in all performance indicators. The paper confirms the practicality of integrating blockchain technology into corporate financial management, demonstrating its ability to significantly boost the efficiency of financial operations and enhance the security of financial data. This method is of great value for practical implementation in the industry.
