zkBridge

zkBridge is a trustless, efficient, secure, and universal cross-chain bridge with advanced zero-knowledge proof technology. zkBridge uses zkSNARKs to enable a prover to efficiently convince the receiver chain that a certain state transition happened on the sender chain.

What is zkBridge?

zkBridge is a zero-knowledge-powered cross-chain protocol developed by Polyhedra Network. It enables secure, trustless data and asset transfers across different blockchains without compromising user privacy. The protocol utilizes zkSNARKs to verify transactions between blockchains without revealing sensitive details, allowing users to move assets, messages, and credentials across chains like Ethereum, BNB Chain, and more in a secure and scalable way.

How Does zkBridge Work?

zkBridge leverages zkSNARKs (zero-knowledge succinct non-interactive arguments of knowledge) to enable fast, private, and verifiable transactions across multiple blockchains. These cryptographic proofs allow users to confirm that a transaction is valid without revealing the underlying data. The protocol generates cryptographic proofs on the source chain and verifies them on the destination chain, avoiding the need for centralized relayers or trust assumptions.

What Makes zkBridge Unique?

zkBridge stands out due to its use of zero-knowledge proofs, ensuring secure and private cross-chain transactions. Key features include: 1. Trustless Interoperability: Enables secure asset transfers without relying on centralized intermediaries. 2. Scalability: Efficient proof generation and verification allow for high transaction throughput. 3. Privacy Preservation: Transactions are verified without exposing sensitive information. 4. Versatility: Supports various use cases, including token transfers, message passing, and NFT transfers across multiple blockchains.

Who Are the Founders of zkBridge?

Polyhedra Network, the developer of zkBridge, was co-founded by Tiancheng Xie and James Zhang. Tiancheng Xie serves as the Chief Technology Officer (CTO), bringing expertise in zero-knowledge proofs and blockchain interoperability. James Zhang is a co-founder, contributing to the strategic direction and growth of the company.
