Privacy Layer with zk-SNARKs & zk-STARKs

BitNetChain’s Privacy Layer uses zk-SNARKs and zk-STARKs to secure transactions, identities, and contracts with high-speed, low-fee, cross-chain privacy.

Layer 1 native privacy
zk-SNARKs and zk-STARKs are built directly into BitNetChain, not added as a sidechain or extension.
Dual zk proof engine
Combine succinct zk-SNARKs with scalable zk-STARKs for different workloads.
Compliance-ready confidentiality
Keep data private while enabling selective disclosure for audits and regulators.
Identity-aware by design
Integrates with BitNetChain DID and Account Abstraction for user-controlled privacy.

BitNetChain ensures users and assets stay private and secure as they move across multiple blockchains

How is BitNetChain's Privacy Layer different from "privacy coins"?

BitNetChain integrates zk-SNARKs and zk-STARKs into a high-performance Layer 1 with EVM, CosmWasm, and IBC support—letting you combine privacy with DeFi, cross-chain, and enterprise apps.

Can regulators or auditors still verify what they need?

Yes. Selective disclosure lets you reveal only specific fields (such as totals, flags, or aggregated metrics) to authorized parties, backed by zero-knowledge proofs that guarantee correctness without exposing full transaction or user history.

How does the Privacy Layer work with BitNetChain's cross-chain interoperability?

Privacy-preserving state and proofs are generated on BitNetChain, and assets or messages can move through IBC and the Universal Bridge while preserving confidentiality and verifiable correctness across connected networks.

Is the Privacy Layer compatible with both EVM and CosmWasm smart contracts?

The zero-knowledge infrastructure is integrated at the platform level, so both EVM-equivalent contracts and CosmWasm contracts can use the same privacy primitives and verification logic within BitNetChain's multi-VM execution environment.

Do I need to be a cryptography expert to use zk-based privacy?

No. Developers interact with simple SDKs and contract patterns; the zk-SNARK/zk-STARK logic and verification are handled by the protocol and infrastructure, not by your application logic.

Does privacy reduce performance or increase fees?

The design focuses on succinct proofs and batch verification: zk-SNARK proofs are small and fast to verify, while zk-STARKs scale logarithmically with computation, enabling high-volume DeFi and cross-shard operations without degrading TPS or pushing fees above BitNetChain's ultra-low cost model.

Can users choose when to be private vs. transparent?

Yes. Applications can offer opt-in private transfers, private pools, or private identities, while still supporting transparent flows where full on-chain visibility is desired. Selective disclosure gives users and protocols control over what is shared and with whom.
