Abstract: The interest in blockchain technology has grown over the years and its potential was soon perceived for other applications beyond the Bitcoin due to its decentralisation and immutability characteristics. The technology also has some limitations and technical challenges compared to centralised systems, especially in terms of performance and scalability. The current limitations prevent to use blockchain on a large scale for other types of applications, making studies necessary to address these gaps and evolve the technology. Considering this scenario, this paper proposes the L7SP model to work on private blockchain, giving contributions for performance gains, and system management improvement. L7SP provides an intermediate layer of services that allow faster transaction processing and online monitoring. The solution preserves the decentralisation nature of blockchain, so maintaining compatibility with legacy systems. A prototype was implemented to evaluate the model and the results showed performance gains with the L7SP introduction.

Keywords: blockchain; management; performance; scalability.
