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)
