Consensus package includes the Harmony BFT consensus protocol code, which uses BLS-based
multi-signature to cosign the new block. The details are
in Harmony's new [consensus protocol design](https://talk.harmony.one/t/bls-based-practical-bft-consensus/131).
## Introduction to Harmony BFT with BLS signatures
Harmony BFT consensus protocol consist of normal mode and view changing mode which is same as the PBFT(practical byzantine fault tolerance) protocol. The difference is we use the BLS aggregated signature to reduce O(N^2) communications to O(N), which is more efficient and scalable to traditional PBFT. For brevity, we will still call the whole process as PBFT.
