The Robustness of the Tangle 2.0 Consensus Protocol in a Byzantine Environment

Robustness of the Tangle 2.0 Consensus

In this paper, we investigate the performance of the tangle 2.0 consensus protocol in a byzantine environment.

We use an agent-based simulation model that incorporates the main features of the tangle 2.0 consensus protocol.

Our experimental results demonstrate that the protocol is robust to the bait-and-switch attack up to the theoretical upper bound of the adversary s 33% voting weight.

We further show that the common coin mechanism in the protocol is necessary for robustness against powerful adversaries.
