- BNB Chain and Brevis are building a programmable privacy layer based on zero-knowledge proofs to configure privacy.
- Intelligent Privacy Pool on BNB Chain targets Q1 2026 launch with ZK attestations and Association Sets for clean funds.
BNB Chain has extended collaboration with Brevis to develop a programmable privacy layer based on zero-knowledge proofs. This is to facilitate privacy setup capability in favor of various users and compliance requirements.
The initiative moves the network beyond conventional transaction privacy systems that focus mainly on obscuring senders, receivers, and amounts. Instead, the framework is designed to let users verify credentials without exposing full wallet histories or sensitive activity patterns.
We are collaborating with @brevis_zk to build the next level of privacy stack on BNB Chain.
Our aim is to move beyond traditional privacy tools and create a smart and flexible system for everyone. This shift is significant as it introduces valuable use cases.
For users,…

According to the announcement, the privacy model is structured around what information is protected, how protected data may be selectively revealed, and who can access 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 earlier reported that BNB Chain activated the Fourier mainnet hardfork on opBNB, cutting 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 Targets Compliant Private Transfers on BNB Chain
As the first implementation, BNB Chain and Brevis are working with 0xbow to develop an Intelligent Privacy Pool that uses “Association Sets” and ZK attestations. The pool will facilitate private transfers by limiting access to deposits that satisfy some predetermined compliance requirements.
BNB Chain stated that eligibility for private withdrawals will be proven through two pathways. The first use of on-chain provenance verification, where the Brevis ZK Data Coprocessor is used to demonstrate that the funds are from compliant sources. The second uses off-chain account verification through zkTLS, allowing users to prove control of a verified exchange account, such as Binance, without disclosing 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 connected to sanctions exposure or malicious activity, it can be excluded from the Association Set, preventing future private withdrawals.
Beyond private transfers, BNB Chain said the privacy layer could support fair prediction markets. Also, it could help SocialFi platforms verify real users while keeping holdings private. In addition, it may support verifiable AI by enabling training on private data with proof-backed validation. The Intelligent Privacy Pool is expected to launch on BNB Chain in Q1 2026.
As we previously outlined, the BNB token benefited from BNB Chain’s 2025 upgrades that lowered fees by about 98%. The Lorentz and Maxwell updates added parallel execution and extended instruction sets to support higher throughput. At press time, BNB crypto traded at $943.71, up 1% over the past 24 hours.
