This project is used to implement asynchronous BFT.
There are three DAG BFT, names "gradedDag", "Tusk" and "Remora".
"Remora" is our DAG protocol --Remora: "Remora: A Low-latency DAG-based BFT through Optimistic Paths," in IEEE Transactions on Computers, doi: 10.1109/TC.2024.3461309
"qcdag" is the DAG protocol in the paper: [SRDS,23]GradedDAG: An Asynchronous DAG-based BFT Consensus with Lower Latency
"tusk" is the DAG protocol in the paper: [Eurosys'22]Narwhal and Tusk: a DAG-based mempool and efficient BFT consensus

Download our code in your WorkComputer and build it.
You need to change the config_gen/config_template.yaml first, and next you can generate configurations for all Servers.
cd config_gen
go run main.go
Now you should enter the ansible directory to take the next operations.You need to change the ansible/hosts first.
The following code needs to be adjusted according to your actual situation.
ansible -i ./hosts BFT -m authorized_key -a "user=root key='{{lookup('file', '/home/root/.ssh/id_rsa.pub')}}' path='/home/root/.ssh/authorized_keys' manage_dir=no" --ask-pass -c paramiko
ansible-playbook copycode.yaml -i hosts
ansible-playbook copyconfig.yaml -i hosts
ansible-playbook run-server.yaml -i hosts
ansible-playbook clean-server.yaml -i hosts
