# 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) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://tokens-economy.gitbook.io/consensus/categorizing-consensus.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
