According to the blockchain trilemma, the degree of decentralization (DoD), scalability, and security of a blockchain system cannot be maximized simultaneously. Software architects must identify Pareto-optimal configurations of blockchain systems to balance the trade-offs between DoD, scalability, and security, in order to meet the non-functional requirements imposed by their use case. I developed 3SIM, a Palladio-based discrete-event simulator for simulating blockchain systems. 3SIM provides a metamodel that enables software-architecture-focused modeling of blockchain systems, and a simulation model, that gathers the data necessary to compute several output metrics, which are suitable to investigate the blockchain trilemma. 3SIM extends SM-SIM, a blockchain simulator for simulating selfish-mining attacks. Experiments were conducted to demonstrate the plausibility and utility of results produced by 3SIM. The experiments help to gain a better understanding of how different blockchain system configurations influence the manifestation of the blockchain trilemma. | |
