# Decentralized and Secure Blockchain Solution for Tamper-Proof Logging Events
## 6 Conclusions  
The secure storage of log events is a complex task, becoming increasingly important due to the complete digitalization of production processes. This is related to different factors, such as the growing complexity of IT systems, society digitization, or the use of technology in signature processes. Traditionally, these events produced by computer systems have been used internally as a reference for detecting erroneous behavior or tracing operations. Therefore, it could be challenging to use in a judicial process due to the doubts raised by these data that do not comply with the principles of integrity, immutability, or non-repudiation. The DRACSC system introduced a new blockchain-based approach to overcome the limitations of traditional log methods used for communication networks. This solution is designed to address common problems in managing communication equipment, such as error recovery, device configuration, and certification of critical log events generated by company network components. The research produced mixed outcomes during the experimentation phase. On the one hand, the methodology followed fulfilled its intended function of preserving coherence, persistence and non-repudiation of the data. However, considering the inherent characteristics of blockchains, the choice of implementation becomes a crucial factor in achieving satisfactory performance. Solana demonstrated exceptional performance, establishing itself as a viable choice for implementing this solution with favorable times for a moderate number of events and lower transaction costs. Conversely, Cardano's feasibility is somewhat limited, as it exhibits higher response times for this specific use case. This limitation significantly reduces the number of events, resulting in higher transaction costs. However, it is worth noting that Cardano's capability to include metadata in transactions adds substantial value for certifying log events. Therefore, each option caters to opposing scenarios, and this duality should be regarded as an advantageous aspect

Despite this, the selection of a new network with optimal performance could be compromised in the medium term due to the widespread adoption of blockchain technology. This work also contributes by making the research code accessible as open source, promoting transparency and collaboration within the scientific community. The code will be publicly accessible through the specified repository at [[https://github.com/jdmorei/seclogs](https://github.com/jdmorei/seclogs)]([https://github.com/jdmorei/seclogs](https://github.com/jdmorei/seclogs)) (accessed on 26 February 2025), encouraging collaboration and advancements in the field. Future work will focus on enhancing security, cost efficiency, and scalability. Regarding security, one of the next developments will be creating a blockchain migration tool due to advancements in classical and quantum computing, which poses risks to existing blockchain protocols. This tool will facilitate secure data and state transfers between blockchains and act as a contingency plan for transitioning to more secure platforms if vulnerabilities arise or if quantum computing threatens current cryptographic methods, thereby ensuring continuity and data integrity. In parallel with these security enhancements, another goal is to increase the number of messages per second and reduce costs. One potential option would be the use of a layer-2 blockchain such as Cardano Hydra. This network improves Cardano's scalability and performance, reaching \(10^{6}\) TPS and introducing the concept of microtransactions at a low cost, making it well-suited for high-frequency payment systems. Hydra achieves this efficiency through State Channels, a technique used in blockchain networks to reduce the number of transactions required for each interaction on the main chain.
