Plain English
Privacy Pools is a privacy protocol designed to provide on-chain financial privacy while letting users prove they’re not associated with sanctioned addresses. Co-authored by Vitalik Buterin in a 2023 paper, the design uses association sets — users prove their deposits are part of a “clean” set of addresses.
How it actually works
Users deposit ETH (or other supported assets); the system records the deposit. When withdrawing to a new address, users prove their deposit is in a curated “association set” excluding known illicit funds. The proof doesn’t reveal which specific deposit is theirs — preserving privacy from the public — but excludes affiliation with sanctioned actors.
What it means for you
Privacy Pools represents the compliant evolution of mixer technology. For HNW users who want transactional privacy without legal exposure, this design — and similar implementations across other protocols — is the appropriate path forward. Consult counsel before adoption; the regulatory landscape continues to evolve.
