In recent news, Ethereum co-founder Vitalik Buterin transferred 50.25 ETH, about $113,000 at current prices. Private poolsthe privacy policy they co-authored in a 2023 research paper, publicly verifying the tool is real money rather than announcing white papers.
The move comes weeks after 0xbow.io launched the protocol on the Ethereum mainnet on March 31, 2025, positioning it as a bridge between user privacy and AML obligations. Buterin putting skin on the game is a brand, not a sale.
A bullish sign for the cryptographic approval architecture on Ethereum.
This amount is deliberately limited to Buterin’s products; This is a performance demonstration and a public statement, not a financial transaction.
The central question that the project raises is that Private Pools can thread the needle that Tornado Cash could not: keep Ethereum’s meaningful secrets and achieve on-chain security and regulations that led to the punishment of its predecessors.

How Private Pools Work Mechanically, and Why Zero-Knowledge Architectures Are Changing the Next Generation
The process here is important to understand. Secret Pools use zero-information for the user to show that their withdrawal is a legitimate “contract”, a small part of the deposits filtered by the analysis of the external chain and stored on the chain, without revealing which part was theirs. The user guarantees the cleanliness of the bag without commitment.
This is not the same as full disclosure, and the distinction is particularly important in regulatory disputes.
Tornado Cash, approved by OFAC in August 2022, did not offer such an option. Each booking was randomly mixed, which meant that users honestly shared anonymous sets with bags tied to North Korea’s Lazarus Group and other legitimate actors, and the moderators had no way to tell them apart. Secret Pools establish a chain gap from the start.
The implementation of 0xbow adds a permission feature: the initial deposits are kept at 1 ETH per address, and the group can suspend new sets of associations if clear sanctions or AML problems arise, while keeping unauthorized withdrawals.
By the opening week, the system recorded more than 21 ETH across 69 individual deposits, including Buterin’s. The popularity is small but growing. The white paper suggests that regulators could require users to release credentials that come from “good” groups instead of just the entire transaction history, making tracking more straightforward and less complicated than Ethereum’s privacy-watching methods.
Ethereum News: Why Buterin’s Secret Pool Moves More Than $113K Transaction
The post-Tornado Cash environment left Ethereum’s cryptographic infrastructure in a difficult position: the most widely used cryptographic tool was allowed, and no reliable permit existed.
Privacy Pools is the most serious attempt to fill this gap, and Buterin’s public use transfers it from a research concept to a living protocol, approved in a single instance.
The larger environmental issue is important here. The The CLARITY Act faces more than 100 amendments as MPs continue to debate the governance of digital assets, including private devices. How Congress and OFAC ultimately deal with the disclosure process will determine whether the Secret Pools become a cornerstone or a footnote.
0xbow is back from Number Group, BanklessVC, and Public Works, Coinbase Venture show the VC’s conviction that legal privacy is a special category that needs to be established.
The roadmap also includes expanding support for ERC-20 products and integrating wallet tools and tracking, which could greatly expand the reach of the protocol beyond traditional ETH users.
Meanwhile, The work of the Ethereum ecosystem continues to generate profitable investments for organizations that monitor the chain.
If regulators see the Proof of Privacy model as the right path to follow, the process becomes a template for the next generation of DeFi-based privacy tools.
If OFAC uses the same blankets it used against Tornado Cash, it predicts the next secret attack and pushes the secret tools underground. The cryptography is fixed. A regulatory decision is not.
Buterin’s 50.25 ETH change is the most reliable confirmation that Private Groups has received. The question of jurisdiction established by association is a variable that determines whether it is subject to administrative review. This question goes directly through OFAC, and through any process that comes out of the current hearings.
