Verification platform Brevis and BNB Chain have announced a partnership with privacy protocol developer 0xbow to launch an "Intelligent Privacy Pool" on the BNB Chain in the first quarter of 2026. This new infrastructure aims to provide crypto users with privacy-preserving transactions while incorporating compliance features to prove funds originate from legitimate sources.
The system, based on 0xbow's existing Privacy Pools framework, offers two primary methods for users to verify eligibility for private withdrawals. The first uses Brevis's ZK Data Coprocessor to cryptographically verify a user's on-chain transaction history, confirming funds are from compliant sources without exposing the full history. The second method, utilizing zkTLS technology, allows users to prove they control a verified exchange account without revealing their identity. Only deposits that pass these checks enter an approved pool from which private withdrawals can be made. The system is also designed to remove deposits linked to sanctions or criminal activity.
The protocol builds on technology initially proposed in a September 2023 research paper co-authored by Ethereum co-founder Vitalik Buterin, who also invested in 0xbow's March 2024 funding round. Buterin has recently argued that privacy technology has matured sufficiently to build applications without centralized intermediaries.
This development comes amid increasing regulatory scrutiny of privacy tools in the crypto sector, highlighted by the recent prison sentences for Samourai Wallet founders and the ongoing case against Tornado Cash developer Roman Storm. The new pool represents a shift from first-generation tools that merely hid transactions to a configurable model that balances confidentiality with verification and accountability.
BNB Chain confirmed the partnership via social media, stating the tool will "unlock privacy-preserving & compliant use cases" such as proving credentials without exposing wallet ownership. 0xbow, which raised $3.5 million in November 2025 from investors including Coinbase Ventures, will provide the underlying technology for the integration on BNB Chain, which currently holds $7.4 billion in total value locked (TVL).
