0xbow has launched Privacy Pools on Ethereum, a cutting-edge privacy tool that has already processed over 21 ETH through 69 deposits, including an inaugural deposit from Ethereum co-founder Vitalik Buterin. This innovative mixnet system leverages zero-knowledge proofs and Association Set Providers to ensure that only “clean” funds are transacted, setting a new standard for regulatory-compliant on-chain privacy.

Privacy Pools on Ethereum: A New Chapter for Blockchain Privacy
0xbow, an emerging leader in privacy-focused blockchain infrastructure, unveiled its Privacy Pools on the Ethereum mainnet on March 31, 2025. Drawing inspiration from a research paper co-authored by Vitalik Buterin and other notable security experts in 2023, the protocol is designed to balance robust privacy features with the strict regulatory compliance demanded by today's financial environment.

How Privacy Pools Work: The Technology Behind the Tool
Zero-Knowledge Proofs & Association Set Providers
Privacy Pools utilize zero-knowledge proofs to enable private ERC-20 token transfers, ensuring that users can deposit and withdraw funds without revealing transaction details. The process is bolstered by Association Set Providers (ASPs)—gatekeeper mechanisms that batch transactions while screening out illicit funds. If a deposit is later flagged, a “ragequit” function allows users to reclaim their funds without impacting the rest of the pool.

Privacy Pools vs. Tornado Cash
Unlike previous mixers like Tornado Cash, which faced sanctions for facilitating unlawful transactions, Privacy Pools are designed with regulatory compliance in mind. By maintaining dynamic association sets that can be updated if any transaction is deemed linked to nefarious activities, the protocol enables users to preserve their privacy while keeping a clear separation from funds associated with criminal behavior.
Key Figures & Early Adoption, Including Vitalik Buterin
Notable Metrics
-
Deposits: Over 69 deposits have been processed.
-
Volume: More than 21 ETH has already flowed into the Privacy Pools.
-
Initial Deposit Cap: Currently set at 1 ETH per transaction, with plans to increase this limit as the system matures.
Endorsements and Early Support

Ethereum co-founder Vitalik Buterin was one of the first to deposit on the platform, lending his support to the initiative. Alongside Buterin, the project has attracted investments from high-profile backers such as BanklessVC, Number Group, Public Works, and various angel investors. This backing underscores the industry’s confidence in a privacy solution that does not compromise on regulatory oversight.
How Can Privacy Pools Balance Privacy and Compliance on Ethereum?
Privacy Pools builds upon earlier developments by projects like Tornado Cash—improving upon its compliance features and learning from past regulatory challenges. The research paper co-authored by Buterin, Ameen Soleimani, Chainalysis researcher Jacob Illum, and academic experts outlines how these privacy protocols can operate within a legal framework, ensuring that the innovation does not open doors for illicit activities.
0xbow envisions a future where privacy is a standard feature on public blockchains. The team emphasizes that while this launch marks an important milestone, it is only the beginning of a broader initiative to “Make Privacy Normal Again.” As the protocol is further battle-tested, both transaction limits and feature sets are expected to evolve in response to user feedback and regulatory developments.
0xbow’s launch of Privacy Pools marks a significant milestone in the evolution of blockchain privacy tools, providing users with a secure way to maintain confidentiality while meeting the necessary legal standards. As the digital asset ecosystem continues to mature, innovations like these are set to play a critical role in shaping a balanced future for decentralized finance (DeFi).
