Discover zk-Bridge
BitNet zk-Bridge is an advanced privacy-preserving cross-chain bridge that enables secure and unlinkable asset transfers between blockchains using advanced zero-knowledge proofs (zk-SNARKs).
Unlike traditional blockchain bridges that reveal wallet addresses, token amounts, and transaction paths, BitNet zk-Bridge ensures complete confidentiality by hiding the sender, recipient, origin chain, and transfer amount.
It integrates seamlessly with existing EVM-compatible infrastructure, requiring no overhaul of current bridge systems. As the signature technology of the BitNet ecosystem, zk-Bridge powers a trustless, decentralized, and private solution for cross-chain interoperability in Web3.
