On April 1, 2025, Ethereum took a major step toward privacy-focused transactions with the official launch of Privacy Pools. This new semi-permissionless tool allows users to conduct private transactions while proving their funds are not linked to illicit activities. Ethereum co-founder Vitalik Buterin strongly supported the initiative and was among the first to make a deposit.
What Are Privacy Pools?
Privacy Pools is an innovative smart contract-based protocol developed by Ethereum developers at 0xbow.io. The system enables users to transact privately while ensuring transparency and regulatory compliance. This is achieved through “Association Sets,” which bundle multiple transactions into an anonymous pool. To prevent misuse, Privacy Pools screens transactions and flags suspicious wallet addresses.
Vitalik Buterin’s Role and First Deposit
Vitalik Buterin has been a vocal advocate for Privacy Pools since its conceptualization. In September 2023, he co-authored its white paper alongside Chainalysis Chief Scientist Jacob Illum and 0xbow.io’s strategic advisor Ameen Soleimani. Buterin further demonstrated his support by making the first 69 deposits, transferring a total of 1 Ether (ETH). According to 0xbow.io, around 21 ETH had been deposited by early adopters before the official launch, reflecting strong initial interest.

Security and Compliance Measures
To ensure the protocol’s safety and reliability, its code underwent rigorous auditing by Audit Wizard, a leading smart contract security firm co-founded by ex-Apple engineer Joe van Loon. The audit confirmed the system’s robustness and compliance with security standards.
Privacy Pools has also garnered backing from prominent investors, including Number Group, BanklessVC, and Public Works, further solidifying its credibility and market relevance.
A More Compliant Alternative to Tornado Cash
Privacy Pools draws inspiration from Tornado Cash, a once-popular privacy tool banned by the U.S. Treasury in 2022 due to its alleged involvement in laundering over $7 billion linked to North Korea. However, in January 2025, a U.S. court ruled the ban unlawful, leading to its removal from the blacklist.
Unlike Tornado Cash, Privacy Pools is designed to offer financial privacy while ensuring regulatory compliance. Users can verify that their funds are not associated with illegal transactions, creating a balanced approach between privacy and security.
Why Privacy Pools Matter
The launch of Privacy Pools comes at a time when crypto-related crimes are a growing concern. According to the 2025 Crypto Crime Report by Chainalysis, illicit transactions in 2024 totaled $41 billion, with estimates suggesting this figure could rise to $51 billion as more suspicious addresses are identified.
The Future of Privacy in Crypto
Privacy Pools represents a significant advancement in secure and compliant blockchain transactions. With the backing of Vitalik Buterin, rigorous security audits, and increasing adoption, this protocol has the potential to redefine privacy in the crypto space. By enabling confidential yet verifiable transactions, Privacy Pools could pave the way for a more secure and regulatory-friendly blockchain ecosystem.
As the crypto industry evolves, tools like Privacy Pools will play a crucial role in balancing financial privacy with transparency, setting new standards for the future of digital finance.
