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)
