- BNB Chain and Brevis are building a programmable privacy layer based on zero-knowledge proofs to configure privacy.
- Intelligent privacy pool enabled BNB Chain goals Q1 2026 launched with ZK certificates and Association sets for clean funds.
BNB Chain has expanded its partnership with Brevis to develop a programmable privacy layer based on zero-knowledge proofs. This is intended to facilitate the ability to set privacy for the benefit of different users and compliance requirements.
The initiative takes the network beyond conventional transaction privacy systems that focus primarily on obscuring senders, recipients and amounts. Instead, the framework is designed to let users verify credentials without exposing full wallet history or sensitive activity patterns.
We’re working with @brevis_zk to build the next level of privacy stack BNB Chain.
Our goal is to go beyond traditional privacy tools and create a smart and flexible system for everyone. This shift is significant because it introduces valuable use cases.
For users,…

According to the announcementthe privacy model is built around what information is protected, how protected data can be selectively revealed, and who has access to the privacy mechanism. BNB Chain said this design approach allows privacy to function as a programmable layer, where applications can choose which attributes remain private, while still proving specific conditions through cryptographic verification.
CNF reported this earlier BNB Chain activated the Fourier mainnet hard fork on opBNB, reducing the block time from 500 milliseconds to 250 milliseconds. Node operators were instructed to upgrade op-geth to version 0.5.9 to maintain client compatibility.
Intelligent privacy pool focuses on compliant private transfers BNB Chain
First implementation BNB Chain and Brevis are working with 0xbow to develop an Intelligent Privacy Pool that uses ‘Association Sets’ and ZK certificates. The pool will facilitate private transfers by limiting access to deposits that meet a number of predetermined compliance requirements.
BNB Chain stated that suitability for private withdrawals will be proven via two routes. The first use of provenance verification on the chain, using the Brevis ZK Data Coprocessor to prove that funds come from compliant sources. The second uses off-chain account verification via zkTLS, allowing users to prove control of a verified exchange account, such as Binance, without revealing their personal identity.
Both methods use zero-knowledge proofs to confirm eligibility while keeping user data private. The Association Set model also includes a removal mechanism. If a deposit is later associated with sanctions exposure or malicious activity, it can be excluded from the association set, preventing future private withdrawals.
In addition to private transfers, BNB Chain said the privacy layer could support fair prediction markets. It can also help SocialFi platforms verify real users while keeping holdings private. Furthermore, it can support verifiable AI by enabling training on private data with evidence-backed validation. The Intelligent Privacy Pool is expected to be launched BNB Chain in Q1 2026.
Like us before outlinedthe BNB token benefited from BNB Chain’s 2025 upgrades that reduced costs by approximately 98%. The Lorentz and Maxwell updates added parallel execution and expanded instruction sets to support higher throughput.
