About the POSDAO and HBBFT consensus category

POSDAO, a Proof-of-Stake (POS) algorithm implemented as a decentralized autonomous organization (DAO). xDai DPOS is a reference implementation with bridged Dai as a native and DPOS as a staking token.

The reference runtime is implemented in Solidity with AuRa + RanDAO on the protocol level. The POSDAO implementation will be upgraded to HoneybadgerBFT consensus later on.
