\section{Conclusion} \label{sec:conclusion}
|
|
|
|
We have proposed a new Byzantine-fault tolerant consensus algorithm that is the
|
|
core of the Tendermint BFT SMR platform. The algorithm is designed for the wide
|
|
area network with high number of mutually distrusted nodes that communicate
|
|
over gossip based peer-to-peer network. It has only a single mode of execution
|
|
and the communication pattern is very similar to the "normal" case of the
|
|
state-of-the art PBFT algorithm. The algorithm ensures termination with a novel
|
|
mechanism that takes advantage of the gossip based communication between nodes.
|
|
The proposed algorithm and the proofs are simple and elegant, and we believe
|
|
that this makes it easier to understand and implement correctly.
