Privacy Pools were proposed by Buterin et al.\ \cite{buterin2023privacy} as a complement to zero-knowledge privacy protocols. The framework builds on Tornado Cash \cite{pertsev2019tornado}, which demonstrated practical on-chain privacy via Groth16 proofs. Zcash \cite{hopwood2016zcash} pioneered zero-knowledge transaction privacy using zk-SNARKs.
Association sets relate to the concept of ``exclusion proofs'' studied in the context of Certificate Transparency \cite{laurie2013revocation}. The ASP model extends the compliance oracle concept from DeFi \cite{chainanalysis2023}.
Poseidon hash \cite{grassi2021poseidon} is optimized for ZK circuits and used in multiple privacy protocols including Semaphore \cite{semaphore2020} and Mina Protocol \cite{mina2020}.
