npm i
node main.js

• Async BA
• PBFT
• VMware BA
• Algorand
• HotStuff BFT (with a naive view synchronizer)
• Libra BFT

• Partitioner: partition network
• VMware Static Attacker: static attacker for postponing VMware basic BA
• VMware Adaptive Attacker: adaptive attacker for postponing VMware VRF BA

Modify config.js to adjust the network environment, BFT protocol, number of nodes, attackers, etc.

The examples directory contains several scripts to run our experiments.

We provide a python tool to visualize the execution of a BFT protocol. Please refer to the README.md file inside the visualization directory for more information.
