We introduce a three-tiered approach to validate blockchain consensus mechanisms, exemplified through the IOTA 2.0 protocol. Traditional methods often struggle to link theoretical constructs with real-world performance, a gap our methodology aims to bridge. We offer a comprehensive framework that transitions from abstract concepts to empirical insights by integrating theoretical models, simulation environments, and real-node testing. Applying this to IOTA 2.0, we validate its consensus mechanism across theoretical, simulated, and practical scenarios, demonstrating our method’s ability to enhance the understanding and optimization of distributed ledger technologies (DLTs).
