# Proof of Zero (PoZ) PoZ is an evolution of actual PoS, with the main difference that is capable of Zero-Knowledge transactions. PoZ gives every users the chance of earning interest over their owned coins, just as standard Proof of Stake. Last but not least PoZ is far away more cheap than PoW, in term of power & processor consumption. Zcrypt is an anoymouc cryptocurrency that uses zero knowledge proofs. It uses a Proof of Work/Proof of Stake protocol with a new algorithm, LyraZ. ## Used in * ZCrypt --- # 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/chain-based-proof-of-capacity-space/proof-of-zero-poz.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.
