Key Takeaways:
- Ethereum launches Privacy Pools via 0xbow.io, enabling private transactions while filtering out illicit ties through dynamic “Association Sets.”
- Vitalik Buterin publicly backed the project and made the first deposit; the tool includes a “ragequit” function for fund retrieval if flagged.
- The launch follows regulatory scrutiny of privacy tools like Tornado Cash, with Privacy Pools aiming to balance privacy and compliance.
Ethereum has launched a new privacy-focused tool called Privacy Pools, enabling users to make anonymous transactions while proving they’re not tied to illicit activity.
Developed by 0xbow.io, the protocol debuted on March 31 with support from Ethereum co-founder Vitalik Buterin, who also made the first deposit.

The system uses “Association Sets” to group legitimate transactions, ensuring no ties to bad actors like hackers or scammers.
If a deposit is later linked to crime, it can be excluded without affecting others, and users can trigger a “ragequit” to reclaim their funds.
Privacy Pools aims to strike a balance between financial privacy and regulatory compliance, offering a contrast to tools like Tornado Cash, which was sanctioned for its role in money laundering.
The protocol currently caps initial deposits at 1 ETH to allow for careful testing, and its code has been audited by Audit Wizard, a smart contract security firm.
The concept stems from a September 2023 white paper co-authored by Buterin and others, which has been downloaded over 12,000 times and cited in multiple academic works.
Backed by firms like BanklessVC and Number Group, Privacy Pools enters a market where over $41 billion in illicit crypto transfers were recorded in 2024.
The initiative hopes to “Make Privacy Normal Again” while addressing past concerns around crypto privacy tools.
