Polyhedra Network has integrated its cross-chain interoperability protocol zkBridge with Flare.

According to an announcement on Aug. 27, the integration of Polyhedra will help developers on Flare (FLR), the blockchain for data platform, tap into cross-chain security with zero-knowledge proofs.

The integration follows the Polyhedra Network community’s approval of a proposal that sought to bring zkBridge, one of LayerZero (ZRO)’s decentralized verifier networks, to Flare. With the arrival of zkBridge DVN on Flare, developers can now leverage ZK proofs technology to build and deploy efficient cross-chain applications.

Integration to boost Flare DeFi ecosystem

Key to the interoperability is zkBridge’s use of zero-knowledge technology zkSNARKs for multi-chain relay and verification of block headers and for consensus.

A system that offers a 2-layer recursive proof environment allows for fast and low-cost proof generation and verification. Batching makes it possible for on-chain verification of transactions from different blockchains into a single proof.

Decentralized applications deployed on Flare can now get data from other chains or networks via zkBridge. The scenario allows developers to build cross-chain dApps for DeFi, including prediction markets, trading and perps.

“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.”

Apart from RWAs and tokenization, Flare’s smart contracts platform supports use cases such as machine learning, artificial intelligence, gaming and social finance. Flare’s FAssets allows for Bitcoin to connect with other blockchains to unlock the benefits of DeFi.
