Polyhedra Network has integrated its cross-chain interoperability protocol, zkBridge, with Flare. This integration aims to enhance cross-chain security for developers on Flare by utilizing zero-knowledge proofs.

According to an announcement on August 27, the integration follows the Polyhedra Network community’s approval of a proposal to bring zkBridge, a decentralized verifier network, to Flare. With zkBridge now available, developers can leverage ZK proofs technology to build and deploy efficient cross-chain applications.

Integration to Boost Flare DeFi Ecosystem

Key to this interoperability is zkBridge’s use of zero-knowledge technology, zkSNARKs, for multi-chain relay and verification of block headers and consensus. The system offers a 2-layer recursive proof environment, allowing for fast and low-cost proof generation and verification. Batching enables on-chain verification of transactions from various blockchains into a single proof.

Decentralized applications deployed on Flare can now access data from other chains or networks via zkBridge. This capability allows developers to create cross-chain dApps for DeFi, including prediction markets, trading, and perpetual contracts.

“Polyhedra’s zkBridge adds an additional security layer to LayerZero’s interoperability protocol and will be welcomed by Flare developers and users alike. Its integration is a sign of the growing support for Flare from cross-chain protocols and demonstrates the value of ZK technology in making it easier for value to flow freely between networks.”

Besides Real-World Assets (RWAs) and tokenization, Flare’s smart contracts platform supports various use cases such as machine learning, artificial intelligence, gaming, and social finance. Flare’s FAssets allows Bitcoin to connect with other blockchains, unlocking the benefits of DeFi.
