## 4 Experiments and Results Discussion
### Results and Discussion  
Through a series of experiments on the system prototype, parameters that can be used for reference in future project deployment were obtained, including the time window size, the block size and the number of block production nodes (delegates). Under reasonable parameter settings, the system has a feasible submission response time, query delay and throughput. Under different numbers of nodes and delegate offline rates within the Byzantine fault tolerance range, the system still shows good performance, scalability and reliability. By comparison with different architecture schemes, the proposed scheme in this paper, including the triple-blockchain architecture and improved DPoS consensus, is superior. Furthermore, through performance and reliability analyses as well as testing of CPU utilization and P2P network traffic, it shows that DPoS is more suitable for the proposed system than any other mainstream blockchain consensus. Finally, some analysis is conducted on the possible negative behaviors that may occur in the system, indicating that the system has a certain level of security.  
Based on blockchain-related technologies, the OSCMS not only explores a comprehensive range of solutions for the decentralized transformation of an OS ecosystem but also focuses on code control, incentive, interaction and cooperation, automation, transparency and fairness of rights and responsibilities. Compared to traditional OS governance methods mentioned in Section 2.2.1, the OSCMS has the following advantages:  
* The OSCMS supports the rapid collection of global information, which is immutable and traceable. OSCMS can record the relationship between projects through smart contracts, and it can also provide easily accessible datasets for technologies such as machine learning.
* The token and decentralized reputation supported by blockchain are more conducive to incentives.
* The OSCMS has reshaped the trust model in the organization, trustlessness, enabling interaction and collaboration anywhere, anytime. A new identity management mechanism compatible with multiple communities has also been implemented in the OSCMS.
* Automation relies on smart contracts, which have higher transparency and credibility.
* The inherent decentralization of blockchain drives transparency and fairness in the governance process. Even delegates elected through the decentralized method are subject to comprehensive supervision. OS users can fully participate in every aspect.  
Section 2.2.2 analyzes the application of blockchain in some related scenarios, which did not comprehensively discuss OS governance. However, in one or several aspects, they provide a reference for the study of an OSCMS. The OSCMS also improves their shortcomings:  
* The requirements for the skills and costs of the participants have been reduced. Automation has been fully utilized, and some theft issues have been resolved through process coordination.
* The evaluation process has been redesigned to avoid losing credibility of the token or reputation.
* The identity authentication and permission management of the blockchain system have been studied, and solutions that are compatible with major communities have been proposed.
* These studies did not discuss the fairness and trustworthiness of consensus, and there was no in-depth discussion on the selected miners or supervision board. In the OSCMS, smart contracts cannot be freely published by someone or an organization. Delegates are transparently elected with limited power and subject to supervision by everyone.
* A novel triple-blockchain architecture is proposed, with higher efficiency and more coordinated relationships.
