The protocol core logic implementation is as simple as the one + specified in our paper. See ``consensus.h`` and ``consensus.cpp``. + +- Modular design. You can use abstraction from the lowest level (the core + protocol logic) to the highest level (the state machine replication service + with network implementation) in your application, or override/redefine the + detailed behavior to customize your own consensus. + +- Liveness decoupled from safety. The liveness logic is entirely decoupled from + safety. By defining your own liveness gadget ("PaceMaker"), you can implement + your own liveness heuristics/algorithm. The actual performance varies + depending on your liveness implementation, but the safety is always intact. + +- Friendly to blockchain systems. A PaceMaker could potentially be PoW-based and + it makes it easier to build a hybrid consensus system, or use it at the core of + some cryptocurrencies. + +- Minimal. The project strives to keep code base small and implement just the + basic functionality of state machine replication: to deliver a consistent + command sequence to the library user. Application-specific parts are not + included, but demonstrated in the demo program. + +Try the Current Version +======================= + +NOTICE: the project is still in-progress. Try at your own risk, and this +section may be incomplete and subject to changes. + +:: + + # ensure openssl and libevent are installed on your machine + cmake -DCMAKE_BUILD_TYPE=Release . -DCMAKE_CXX_FLAGS="-g -DHOTSTUFF_ENABLE_LOG_PROTO" -DBUILD_SHARED=ON + make + + # start 4 demo replicas with ./run_replicas.sh + # start the demo client with ./run_client.sh |
