Blockchain-Based Engineering Bidding Method Patent Granted: Enhancing Transparency and Security in Engineering Bidding

On February 13, 2025, the State Intellectual Property Office of China announced that Anhui Anzao Engineering Technology Consulting Service Co., Ltd. successfully obtained a patent for a "Blockchain-Based Engineering Bidding Method," with publication number CN119398888A and an application date of November 2024. This patented technology is expected to significantly improve transparency and security in engineering bidding, addressing long-standing industry challenges.

This patented technology aims to revolutionize the traditional engineering bidding process using blockchain technology, creating a fairer, more just, and efficient bidding environment. The patent abstract details the steps of this blockchain-based method, emphasizing innovations in enhancing random number security.

Specifically, the method first obtains a random number intended to be sent with the bid, calculating its bit length and entropy to assess its complexity. The bit length and complexity are then input into a collision assessment model to calculate the probability of collision. For further optimization, the method adjusts the collision probability based on network throughput.

Next, the system presets a standard collision probability threshold and calculates the distribution difference between the optimized collision probability and this threshold. Only when the distribution difference falls within the allowable range of standard error is the corresponding random number sent to the bidding node. Through these rigorous steps, the patent effectively enhances the security of the system's random numbers, resolving the imbalance between random number security and computational performance common in existing engineering bidding systems.

Traditional engineering bidding systems often face numerous challenges. For example, the security of random number generation is difficult to guarantee, making them susceptible to manipulation or technical attacks, leading to unfair bidding results. Furthermore, computational performance limitations can affect system efficiency and stability. This blockchain-based bidding method offers a solution to these problems.

Blockchain's decentralized, transparent, and immutable nature makes it an ideal tool for addressing security and efficiency issues in engineering bidding systems. By recording the bidding process on the blockchain, all participants can view bidding information in real-time, ensuring transparency and preventing manipulation and fraud. The distributed ledger technology of blockchain also improves system fault tolerance and stability, avoiding risks from single points of failure.

Anhui Anzao Engineering Technology Consulting Service Co., Ltd., the applicant, was established in 2004 and is headquartered in Hefei, Anhui Province. It's a company primarily engaged in business services, with registered and paid-in capital of 10 million RMB. According to Tianyancha data, the company has invested in two other companies, participated in over 5,000 bidding projects, holds three patents, and has six administrative licenses. This demonstrates the company's extensive experience and expertise in engineering consulting, providing a solid foundation for its successful patent application.

The successful application of this blockchain-based engineering bidding method marks a significant milestone in technological innovation within the engineering bidding field. It provides new technical means for building a fairer, more just, transparent, and efficient engineering bidding system and is expected to be widely applied to various engineering projects in the future. The positive impact will extend beyond improved bidding efficiency and security to promoting the healthy development of the entire engineering industry and optimizing the allocation of social resources.

The application of this technology will effectively reduce corruption risks in the bidding process, improve resource allocation efficiency, and enhance the fairness and transparency of the bidding process. For bidding companies, this technology can reduce bidding costs and improve the success rate. For government and regulatory agencies, it can strengthen supervision of the bidding process and ensure the fair allocation of public resources.

The technology also provides a new direction for the future development of the engineering industry. With the continuous development and improvement of blockchain technology, blockchain-based engineering bidding methods will be more widely applied and improved. In the future, this technology is expected to integrate with other advanced technologies such as artificial intelligence and big data to form a more intelligent and efficient engineering bidding system, further optimizing the management and implementation of engineering projects.

This patented technology is not only an innovation in existing engineering bidding methods but also a powerful driver of the development of the entire engineering industry. It provides a solid technological foundation for building a fairer, more just, transparent, and efficient engineering bidding system and is expected to be widely applied to various types of engineering projects in the future, thereby promoting the healthy development of the engineering industry and the optimal allocation of social resources. The innovative achievements of Anhui Anzao Engineering Technology Consulting Service Co., Ltd. deserve industry attention and emulation, setting an example for future technological development in the engineering bidding field. This technology is also of significant importance for improving the efficiency and transparency of national infrastructure construction.

The innovation lies in the ingenious combination of blockchain technology's advantages and the practical needs of engineering bidding, effectively solving the security and efficiency problems of traditional methods. Its application prospects are broad, and it is expected to play an important role in promoting the digital transformation and high-quality development of the engineering construction field. Future research directions could focus on further improving the algorithm, enhancing its security, efficiency, and applicability to better adapt to the needs of different types of engineering projects. This will contribute to the sustainable development of China's engineering technology field.
