# Categorizing consensus

We propose the following consensus categories

* Proof of Work
* Chain-based Proof of Stake (includes LPoS, Proof of Importance)
* PBFT and BFT-based Proof of Stake (includes DPoS, Ouroboros, Byteball, and PBFT)
* Hybrid models: Proof of Activity and hybrid PoW/PoS
* Proof of Burn (shares some characteristics with chain-based Proof of Stake)
* Proof of Capacity/Space (shares some characteristics with PoW but also suffers from a \[lighter] Nothing-at-stake problem)
* Trusted computing algorithms (e.g. PoET)
* DAGs are mostly using a DPoS-like algorithm, (except IOTA, which uses PoW)
